Chapter 1Receiving and Installation Soft Start Application
The ALTISTART 46 (ATS46) Soft Start offers state-of-the-art acceleration and deceleration control of standard three-phase asynchronous induction (squirrel cage) motors. The ATS46 controller uses a new patented technology to control the motor performance based on the motor torque rather than simple voltage- or current-based control. Advanced control algorithms are incorporated to ensure smooth rotation throughout the starting ramp without mechanical instability at the end of starting. A microprocessor continuously monitors the motor and controller performance to provide maximum protection of the controller, motor, and driven machinery. A variety of starting and stopping modes are standard. A digital keypad provides accurate controller setup and continuous motor performance display. The ATS46 motor controller is available in 21 current ratings from 17 to 1200 amps. All models use a common control module for consistent and simple set up. ATS46 controllers are rated for use with 208/230, 380/400, or 460/500 V motors, and are selfadjusting for a 50 or 60 Hz supply frequency.
Some of the terms and acronyms used in this manual are dened in Table 1. Table 1: Denition of Terms

Chapter 1Receiving and Installation Handling the Controller
HANDLING THE CONTROLLER
Do not remove the ALTISTART 46 (ATS46) controller from the carton until it is at the nal installation site. The carton provides protection and prevents damage to the controllers exterior. Handle the controller carefully after removing it from the carton to avoid damage to the internal components, frame or exterior. Once removed from the carton, the controller can be handled: With a hoist. When hoisting the controller, attach a spreader bar to the two lifting rings on top of the controller as shown in Figure 6. In a horizontal position, with the back of the controller resting on a pallet.
NOTE: Do not rest unit directly on bus bar connectors.
HANDLING AND LIFTING HAZARD Keep area below any equipment being lifted clear of all personnel and property. Use lifting method shown in left-hand portion of Figure 6. Failure to follow this instruction can result in death or serious injury.
Hoisting the ATS46 Controller
The serial and model numbers of the ATS46 controller appear on the bar code sticker located on the front right side of the component.
Record the serial number below. This number will assist us in helping you in the future:
Serial Number: 6W
Chapter 1Receiving and Installation Installation Precautions
Follow these precautions when installing the ATS46 controller:
HAZARDOUS VOLTAGE Read and understand this manual in its entirety before installing or operating ATS46 controllers. Installation, adjustment, repair, and maintenance of these controllers must be performed by qualied personnel. Disconnect all power before servicing the controller. DO NOT touch unshielded components or terminal strip screw connections with voltage present. Install all covers before applying power or starting and stopping the controller. User is responsible for conforming to all applicable code requirements with respect to grounding all equipment. See Figures 1-5 on pages 5-7 for grounding points. Many parts in the controller, including printed wiring boards, operate at line voltage. DO NOT TOUCH. Use only electrically-insulated tools while making adjustments. Before installing the controller: Disconnect all power. Place a DO NOT TURN ON label on the controller disconnect. Lock disconnect in open position. Electrical shock will result in death or serious injury. Voltage and frequency specications for the input line must match the controller conguration. A disconnect switch must be installed between the input line and the controller.
HAZARDOUS VOLTAGE The solid-state switches of the ATS46 controller power circuit do not provide complete isolation from the line. Due to leakage currents through the solid-state switches, hazardous voltages can be present on the controller load-side power circuit whenever power is applied to the line side of the controller. Disconnect all power before servicing the controller or motor. Electrical shock will result in death or serious injury. When using an isolation contactor, certain sequencing must be observed with respect to the run signal supplied to the ATS46 controller. During starting of the controller, closure of the isolation contactor generally should precede or coincide with the application of the controller run command. If line power is not detected at the L1, L2, and L3 terminals of the controller within 500 ms of this run command, a Phase Failure fault will occur. The circuit diagrams use this feature of the controller, as displayed in Figures 21 and 22. External overcurrent protection devices (OCPD) in the form of fuses or a circuit breaker must be installed on the line-side connections of the ATS46 controller. The maximum recommended OCPD rating, along with the associated controller shortcircuit withstand rating, is listed in Appendix A.
OVERCURRENT DEVICES MUST BE PROPERLY COORDINATED OCPD must be installed on the line-side of the ATS46 controller to achieve published short-circuit withstand ratings. Do not exceed the maximum OCPD ratings shown in Appendix A. Do not connect the controller to a power feeder whose short circuit capacity exceeds the controller short circuit withstand rating shown in Appendix A. Failure to follow this instruction can result in death or serious injury. Power factor correction capacitors should not be connected to a motor controlled by an ATS46 controller. If power factor correction is required, the capacitors must be located on the line-side of the controller. A separate contactor should be used to switch the capacitors off when the motor is off, or during acceleration and deceleration.
EQUIPMENT DAMAGE HAZARD Do not connect power factor correction capacitors to the load-side power circuit of the ATS46 controller. Failure to follow this instruction can result in injury or equipment damage. The ATS46 controller uses solid-state power switches to control motor power. When checking the condition of conductor or motor insulation, do not connect the high potential dielectric test equipment or insulation resistance tester to the controller since the test voltages used may damage the controller. Always disconnect the controller from the conductors or motor before performing such tests.
EQUIPMENT DAMAGE HAZARD Do not perform high potential dielectric tests on circuits while the circuits are connected to the ATS46 controller. Any circuit requiring high potential dielectric tests must be disconnected from the controller prior to performing the test. Failure to follow this instruction can result in injury or equipment damage. The ATS46 controller contains electronic protection to detect and signal failure of the solid-state switches. Since the solid-state switches may be incapable of completely blocking motor power should a failure occur, auxiliary isolation on the line-side of the controller is required. The isolation device must be capable of operation via command from the Fault relay of the controller. An isolation device consisting of either a circuit breaker incorporating a shunt trip coil or an electromagnetic contactor can be used to open the controller power circuit in the event of a controller fault. Refer to Figures 20 through Figures 22 on pages 22 through 24 for typical circuit diagrams that display the logic controlling the isolation device via the fault relay.
MOTOR OVERHEATING Failure of the solid-state switches on the ATS46 controller can cause single-phase operation of the motor. Use an isolation device consisting of either a circuit breaker equipped with a shunt trip coil or an electromagnetic contactor to open the line-side of the controller. The isolation device must be capable of interrupting motor locked rotor current. Connect the fault relay of the controller to open the isolation device in the event of a controller fault. Failure to follow this instruction can result in injury or equipment damage.
BRANCH CIRCUIT CONDUCTOR HAZARD If System grounding is not adequate to ensure ground fault levels exceed 1300% of motor full load amps (FLA), then this device may not ensure protection of branch circuit conductors. In this case, external ground fault protection must be properly coordinated. Recommended solutions include: Time delay fuses coordinated to 125% of motor FLA. Fuses listed in Recommended Component List on page 26 are sized to ensure proper coordination and may be used for applications that do not require start times longer than 50 seconds at 300% current limit or 20 seconds at 500% current limit. Equipment ground fault protection. If using a circuit breaker or fuses sized larger than 125% of motor FLA as OCPD, an external ground fault relay or circuit breaker with ground fault detection should be coordinated with controller. An application diagram showing coordination of an equipment ground fault relay is shown in Figure 20 on page 22. External overload relay. For multi-motor applications, applications in which motor does not match the controller size, or applications that use a full voltage bypass scheme, an external overload relay can be coordinated to protect conductors from a high-impedance ground fault. Failure to follow this instruction can result in death or serious injury.
Chapter 1Receiving and Installation Mounting Precautions
Follow these precautions when mounting the ATS46 controller: Controllers are open devices and must be installed in suitable enclosures or controlled access areas. The environment around the controller must meet Pollution Degree 3 requirements as dened in NEMA ICS1-1 or IEC 664-1.
HAZARDOUS VOLTAGE ATS6 controllers are open devices and must be mounted in a suitable enclosure. Electrical shock will result in death or serious injury. When installation surface is not even, put a spacer behind the controller mounting pads to eliminate gaps. Fastening the controller exterior to an uneven surface may damage the controller. When installing in an enclosure, cover the device to prevent metallic debris from falling into the controller. The ATS46 controller generates heat and must be properly ventilated. Refer to Thermal Considerations for Sizing Enclosures on page 13 to determine power dissipated. When several controllers are installed in a control panel, arrange them in a row. Do not stack controllers. Heat generated from the bottom controller can adversely affect the ambient temperature around the top controller.
CONTROLLER OVERHEATING Mount the ATS46 controller within 15% of vertical. Do not locate the controller near heat radiating elements. Electrical current through the controller will result in heat losses that must be dissipated into the ambient air immediately surrounding the controller. To prevent thermal fault or equipment damage, provide sufcient enclosure cooling and/or ventilation to limit the ambient temperature around the controller. Failure to follow this instruction can result in injury or equipment damage. Mounting in General Purpose Metal Enclosure Degree of protection: NEMA Type 1 (IP23). To ensure adequate air ow inside the controller, follow these guidelines: Leave sufcient space around the controller (see Figure 7): A 2 in (50 mm), B 4 in (100 mm). Provide ventilation. Ensure sufcient ventilation. If necessary, install a cooling fan with lters.
Chapter 1Receiving and Installation Remote Mounting Keypad
Mounting in Dust and Damp-proof Metal Enclosure
Degree of protection: NEMA Type 12 (IP54). Provide a stirring fan to circulate air inside the enclosure and prevent hot spots in the controller. This allows operation of the controller in an enclosure with a maximum internal temperature of 140 F (60 C). Derate the controller current In by 1.2% per C for temperatures above 40 C or, where applicable, use a shorting contactor (duty cycle not to exceed 2 starts per hour). Do not use insulated or non-metallic enclosures as they have poor thermal conduction. Locate the fan and ensure that ambient temperature around the controller is within the specications. To reduce temperature rise within the enclosure, use a shorting contactor (47 A units and higher). Use a heat exchanger when necessary to keep internal temperatures within specication.
i 60 C
Figure 8: Thermal Considerations for Sizing Enclosures
Ventilation for Dust and Damp-proof Enclosure
When mounting the ATS46 controller in an enclosure, use the enclosure manufacturers recommendations for proper sizing based on thermal considerations. For this, it is necessary to sum the power dissipated by each device within the enclosure. Table 6 lists the steady state power dissipation for the ATS46 controller operating at rated current.

Chapter 2Wiring Wiring
Good wiring practice requires the separation of control circuit wiring from all power (line and load) wiring. Power wiring to the motor must have the maximum possible separation from all other power wiring. Do not run in the same conduit; this separation reduces the possibility of coupling electrical noise between circuits. When wiring ATS46 controllers, follow the wiring practices required by national and local electrical codes. In addition, follow these guidelines: Use metallic conduit for all controller wiring. Do not run control and power wiring in the same conduit. Separate metallic conduits carrying power wiring or low-level control wiring by at least 3 in (8 cm). Separate non-metallic conduits or cable trays used to carry power wiring from metallic conduit carrying low-level control wiring by at least 12 in (30.5 cm). Cross the metallic conduits and non-metallic conduits at right angles whenever power and control wiring cross.
The control circuit is completely independent of the power circuit. To select control voltage, follow the instructions on the label located on the top of the controller: 208-240 V: move terminal cover from position 230 to position 460/500 V and connect single phase voltage supply to terminals C and 230 V. 380-415 V: move terminal cover from position 400 to position 460/500 V and connect single phase voltage supply to terminals C and 400 V. 440-500 V: check that exposed control terminals are marked C and 460/500 V. If not, move blue terminal cover from 460/500 V terminal and connect single phase voltage supply to terminals C and 460/500 V. The power circuit adapts automatically to the input line voltage over a range of 208 to 500 V (10%) for standard controllers.

Chapter 2Wiring Control Connections
Although all control inputs and outputs of the controller are isolated from the input lines, follow these control wiring precautions: Keep control wiring conductor runs short and direct. Ensure that the control contacts used with the controller inputs are rated for operation at open circuit voltages of 24 VDC and closed circuit currents of 10 mADC. The analog output requires twisted cable with a pitch of 12 inches. Use a cable shield. The shield must be terminated to ground at one end only. Ensure that the coils of all relays and solenoids connected to the output contacts of the controller are equipped with appropriate transient suppressors. For proper control wiring, route conductors to avoid contact with other voltage potentials in the controller. Wire insulation must have the appropriate voltage rating for the voltage present.

May be congured for fault indication or for control of isolation contactor. Normal state of relay is the state with all power removed from the controller or if a fault is detected. When congured for fault indication, contacts will energize after successful completion of internal diagnostics and will de-energize if a fault is detected. If congured for control of an isolation contactor, relays will energize after a run command is issued and de-energize after deceleration is complete or if a fault is detected. If using automatic restart, the status of the fault relay is dependent on the type of fault and conguration of the R1 relay. Refer to Chapter 4 for Fault relay status, if using automatic restart. Relay contact will close when the controller has completed the acceleration ramp and the current draw of the motor is less than 130% of the motor FLA (or the setting of In) setting. Contact is coordinated with the thyristors on a stop command or fault condition. This relay is typically used to control a contactor that bypasses the controller after start-up to ease thermal management of the installation. If a shorting contactor is not used, the status of this relay may be indeterminate following a phase failure fault.

KM1 KM1A
The isolation contactor logic closes KM1 upon a start command and opens KM1 after the stop is complete. The RCR (or RFR and RRR for reversing) are timed contacts that must have a time delay greater than the deceleration ramp time or the dynamic braking time. When a coast stop is selected, the time delay must be set for a time that will allow a complete decay of the motor residual voltage. The isolation contactor will open immediately upon a fault. The pilot relay (KM1A) is required when the KM1 contactor coil exceeds the relay rating. Used for reversing applications only, the KM2 must be mechanically interlocked to KM1. A reversing contactor may be used for the combination of KM1 and KM2. In general, the operation of KM2 is identical to KM1. The pilot relay (KM1A) is required when the KM1 contactor coil exceeds the relay rating. The shorting contactor is used to reduce the heat dissipated by the controller when the motor is operating at full speed and voltage. The starter provides proper sequencing of this contactor by the end-start-up relay. When the start is completed, the shorting contactor will be commanded to close. The starter will continue to monitor the motor thermal state and provide motor overload protection. Upon a stop command, the KM3 contactor will open, transferring the motor current to the SCRs to allow for controlled deceleration if desired. The pilot relay (KM3A) is required when the KM3 contactor coil exceeds the relay rating. Refer to Figure 16 on page 20. Transient suppression of all relay and contactor coils (except ST) is recommended to minimize the possibility of electrical interference with the starter electronics and to increase relay contact life. Used in all non-reversing logic (optional in shunt trip) for proper sequencing of contactor logic. When energized, RCR initiates the start sequence. When de-energized, stopping is initiated. Operator controls can be either on/off selector switch, HOA selector switch or start/stop push buttons. RCR remains energized during a fault. Once the fault condition has been cleared, RCR must be de-energized by a stop command then re-energized to restart the controller. Used for reversing applications only, this coil duplicates the functionality of RCR for the forward direction and is interlocked with the RFR relay. Used for reversing applications only, this coil duplicates the functionality of RCR for the reverse direction and is interlocked with the RRR relay. This coil is attached to the shunt trip coil on the disconnect and will energize 2 seconds after a starter fault by the TR timer contact. The time delay is to prevent nuisance tripping of the circuit breaker during controller power-up or during line undervoltage conditions. Used in shunt trip circuit breaker logic only; coil energized upon a starter fault. Used with logic diagrams that use an isolation contactor. The fault relay is energized during normal operation and deenergizes if the starter fault contacts open or if the motor thermal switch (if supplied) opens. FR also provides additional contacts for the starter fault output. Current-sensitive relay for detection of ground current. If relay is energized, operation of the controller is interrupted by placing in series with the run control relay.

To select control operators (push buttons, pilot lamps, and selector switches), control power transformers, and wire management devices (control and power terminal strips, wire terminations) indicated on the referenced control circuit congurations, refer to the latest editions of the Square D product catalogs. Notes: 1. Motor full load currents through 500 hp @ 460 V and 250 hp @ 230 V are taken from UL508 Table 54.2 (NFPA 70, Table 430-150). Above 500 hp @ 460 V and 250 hp @ 230 V, motor full load currents are calculated based upon 1.2 A/hp for 460 V and 2.4 A/hp for 230 V. Motors listed are for standard duty applications. For heavy duty applications, select the next larger controller size. The ambient temperature indicated in the table represents the temperature of the air surrounding the ALTISTART controller. Any additional temperature factors associated with the enclosure system or actual installation ambient temperature must be considered when determining the actual rated current (ICL) of the starter. For operating ambients above 40 C but not exceeding 60 C, the rated current (ICL) of the starter must be de-rated by 1.2% per C. All coils are selected for 120 V, 60 Hz operation. Refer to the Digest for additional coil voltages or auxiliary contact congurations. One block may be added to each contactor. The fuses listed in the Table 11 provide Type 1 protection to the starter and auxiliary power equipment when the power source short circuit current capability is less than or equal to the values listed in Appendix A. Fuse holders listed are for Class R fuses only. Fuse blocks recommended for use with ATS46 models D88 through C48 are Bussmann part numbers. Class L fuses require bolt-on connections to user-supplied power bus work. The molded case switches selected require the addition of operator mechanisms to allow operation from the exterior of an enclosure. Refer to the latest editions of the Square D product catalogs for operator mechanism information. When using a shunt trip relay for SCR fault isolation, order a molded case switch with sufx -1021 for addition of shunt trip coil.

The key to applying a soft start successfully is matching the load to the motor capability while starting with reduced voltage applied. The ALTISTART 46 is factory preset to start the motor for which the controller is rated for standard duty applications. A switch is located behind the removable keypad that can be toggled from standard duty to heavy duty application presets. For standard duty applications, the ALTISTART controller is preset for Class 10 overload protection, a 300% current limit and 10 second acceleration ramp. Typical standard duty applications include most fans and centrifugal pumps. Other standard duty applications include machines such as screw type compressors or conveyors that are started with light or no load. At the standard duty default settings, 10 starts per hour may be achieved for a maximum of 23 seconds per start without tripping. The standard duty horsepower rating of the controller is listed on the device nameplate. Applications requiring long start times, high starting torque, or frequent starting and stopping may require de-rating of the controller or the use of a shorting contactor to bypass the controller once the motor is up to speed.
For heavy duty applications, the ALTISTART controller is preset for Class 20 overload protection, a 350% current limit and 15 second acceleration ramp. Heavy duty applications include high inertia loads or other loads requiring long acceleration times. Some examples of heavy duty applications include grinders, crushers, and presses as well as high inertia fans and saws. For heavy duty applications, the controller must be de-rated by one size. When the duty selector switch is toggled to heavy duty mode, the default motor current setting is adjusted to the rated current of the next lower common motor size. At the heavy duty default settings, 5 starts per hour may be achieved for a maximum of 46 seconds per start without tripping. If a shorting contactor is used to bypass the SCRs after starting, the controller may be used for heavy duty applications at its standard duty rating. Refer to chapter 3 for additional information regarding the factory presets.
The asynchronous motor associated with the ATS46 controller must be able to accelerate the driven load when supplied with reduced voltage and current. When reduced voltage is applied to a motor during acceleration, the current the motor will draw is reduced by the ratio of the voltage applied. The torque produced by a motor varies with the square of the voltage at a xed frequency. The resultant torque produced by a motor then varies with the square of the voltage at a xed frequency. Figure 23 shows the speed/torque characteristics as a function of the supply voltage.

Chapter 3Application and Protection Modes of Starting
A soft start progressively increases voltage to the motor. By ramping the voltage, the ATS46 controller limits the amount of current the motor can draw during starting to a user-dened setting. Figure 24 shows the speed/torque characteristics of a motor as a function of starting current. The ATS46 controller provides optimal acceleration by ramping the acceleration torque within the envelope of curve Td1.

MODES OF STARTING
The ATS46 controller is factory preset for simple, out-of-the-box operation in many applications. The factory preset provides a 10-second acceleration ramp with 300% of the factory preset nominal current. TCS (Torque Control System) ramp is the most widely used acceleration ramp. It is ideal for applications that require a smooth, stepless start. The ATS46 controller uses patented technology to calculate the motor torque continuously . Basing the TCS ramp on the motor torque provides constant acceleration torque ideally suited for most fans, centrifugal pumps, or other variable torque loads. A torque ramp provides a higher level of control than is available with typical voltage ramping or current limiting soft starters. As shown in the diagrams below, torque ramping compared to a current limited start can provide a more linear speed ramp, reduces the surge of acceleration typical for most soft starts and minimizes the motor temperature rise by reducing the amount of current drawn during acceleration .
Torque Ramp Current Limit
Current Limit Torque Ramp
Figure 25: Torque Ramp vs. Current Limit Starting The torque ramp time, or the time to increase from zero torque to the nominal torque of the motor, may be adjusted from 1 to 60 seconds. The initial torque applied is preset for 10% of the motor nominal torque, but may be adjusted from 0 to 100% for maximum exibility and adaptability for varying loads.
Chapter 3Application and Protection Modes of Stopping
As Figure 26 illustrates, the maximum motor torque may be limited to between 10 and 100% of the motor nominal torque. This feature is primarily used to limit acceleration of high inertia or constant torque applications. If used, the torque limit combines with the acceleration ramp and initial torque settings to provide a highly customized acceleration torque prole.
Initial torque 10%
Figure 26: Acceleration with Torque Limit Current Limit Current limit starting is used primarily in high-horsepower applications of limited system capacity. The current limit is adjustable from 150 to 500% of the controller current rating. The current limit setting is always active during start up and overrides all other settings. When the user-dened current limit setting is reached, the torque ramp adjusts to prevent excess current draw. When starting, if the torque is too low due to dry friction, stiff mechanism, or high inertia, the boost function allows the motor to develop increased torque to initiate motor shaft rotation. As Figure 27 shows, the voltage applied during the boost may be adjusted from 50 to 100% of the motor nominal voltage and is applied for 5 cycles of mains power.
Td Boost
Following acceleration ramp
Figure 27: Boost Function
MODES OF STOPPING
The ATS46 controller can be set for freewheel stop, deceleration ramp, or dynamic braking. The default setting is freewheel stop, which removes all voltage from the motor terminals after a stop command. The time the motor takes to coast to rest depends on inertia and resistive torque of the driven load. Deceleration ramping uses the same principles of the acceleration ramp, providing a gradual deceleration. This feature is typically used in pumping applications to prevent hydraulic shocks or water hammer, which may occur if the motor decelerates too quickly. As shown in Figure 28 on page 33, when deceleration ramping is selected, the ramp time may be adjusted from 1 to 60 seconds. The torque threshold at which the ramp ends may also be adjusted from 0 to 100% of nominal torque.
Chapter 3Application and Protection Motor Protection and Diagnostics
Once the torque reaches the threshold value, the controller changes to freewheel mode and the motor coasts to a stop. The threshold setting is useful in pumping applications, which do not require continued deceleration control once the check valve has closed. If the torque is below the threshold setting at a given stop command, controlled deceleration is not activated and the controller changes to freewheel stop.
Figure 28: Torque Ramp During Deceleration InTele Braking InTele Braking is available for applications that require faster than freewheel deceleration time. Impulse braking decelerates the motor to 20% of the rated speed; DC Injection completes the deceleration. The braking level may be adjusted from 0 to 100% to provide gradual ramp. To customize the deceleration ramp, adjust the duration of the DC injection from 20 to 100% of the impulse braking time. If InTele Braking is selected, the controller is preset for 50% braking torque level with a change to DC injection at 20% speed for 20% duration.

MOTOR PROTECTION AND DIAGNOSTICS
The ATS46 controller provides state-of-the-art motor protection. On controllers rated 47 A and higher, motor protective features are available even if a shorting contactor is used to bypass the SCRs after the motor is up to speed. To assist with troubleshooting, the 3-digit LCD displays fault status codes. The controller memory registers and maintains the previous 5 faults, even following power loss. The ATS46 controller is a UL Listed motor controller with integrated motor and controller thermal protection. The motor and controller temperature are continuously calculated based on the controller nominal current and the current that is actually drawn. An electronic circuit, which stores the thermal state of the motor even if the supply power is disconnected, simulates the cooling curve. Overload of any kind over any duration can cause the motor temperature to rise. As Figure 30 shows, the ATS46 controller creates a digital model of the motor temperature based on two thermal images. The rst (T1) represents the level of temperature rise corresponding to iron (motor frame). The second (T2) represents the temperature rise of copper (stator, windings). For each thermal image, two levels of alarm are detected.
An overload pre-alarm is signaled by logic output LO1 when the motor has exceeded its nominal temperature rise threshold. A pre-alarm is signaled when the thermal state exceeds 105% for T1 and/or 130% for T2. A thermal fault signal stops the motor when the temperature rise exceeds the critical threshold. A thermal fault is signaled by relay R1 when the motor thermal state exceeds 110% for T1 and 140% for T2.

Figure 30: Thermal Trip Curves The ATS46 controller is preset to provide Class 10 overload protection for standard duty applications. The ATS46 controller can be adjusted to provide Class 2, 10A, 10, 15, 20, 25, or 30 overload protection, as necessary. Class 2 protection is available for applications such as submersible pumps, where very tight control of motor temperature is required. Class 30 protection is available for applications such as high inertia loading, where a longer than normal starting time is required to accelerate the load to full speed. In addition, the internal overload protection may be disabled if motor protection is provided externally. The various thermal overload protection classes are dened to meet the standards of IEC 947-4-2 for starting from both cold and hot states. Starting from a cold state is dened as the stabilized motor thermal state when the motor is off. Figure 31 shows the approximate trip times for starting from a cold state.

Figure 31: Cold Start Curves Starting from a hot state is dened as the stabilized motor thermal state when the motor has been running at full load capacity. Figure 32 on page 36 shows the approximate trip times for starting from a hot state.
Figure 32: Hot Start Curves Excessive Cycling Prevention To avoid excessive starting and stopping, adjust the time before starting. The range of adjustment is between 0 and 999 seconds. When using a freewheel stop, the ATS46 controller will not accept a new start command during the time after a STOP command is issued and before the motor starts. When using controlled deceleration, a new START command will not be accepted until: the time elapses after the soft stop; or InTeleBraking is complete. The factory preset of two seconds ensures de-magnetization is complete before motor restart.

Stall and Steady State Protection
During steady state operation, the ATS46 controller provides protection from stalling during acceleration and jamming, overcurrent, or underload conditions. To prevent stalling, set the the maximum start time. It ranges from 10 to 999 seconds. If the time to reach full speed exceeds the stall time, a fault is detected and the start is aborted. To protect against jamming after the motor is up to speed, the ATS46 controller detects a fault and aborts motor operation when the current exceeds 5 times the motor rated current for more than 200 ms. This feature is only active when the shorting contactor is used to bypass the controller during steady state operation. The current trip threshold may be adjusted from 50 to 300% of the nominal motor current for additional protection during steady state operation. See Figure 34. If an overcurrent condition exists for more than 10 seconds, an alarm is signalled through logic output LO2. Brief overcurrent conditions are allowed without nuisance tripping if the current decreases to a level 10% or more below the overcurrent limit within 10 seconds.

Figure 34: Current Trip Threshold To protect against underload conditions during steady state operation, the underload limit may be adjusted from 20 to 100% of the motor load state. See Figure 35. An underload fault is detected after 4 seconds of operation below the user-dened level. Brief underload conditions are allowed without nuisance tripping if the loading returns to a level 10% or more above the underload limit within 4 seconds.

Chapter 3Application and Protection Controller I/O Configuration
Protection from Line Faults
The ATS46 controller provides protection from line faults while allowing for continued operation when supplied with typical industrial power that may contain minor disturbances. The ATS46 controller interrupts motor operation if the following fault conditions are detected: Mains supply failure greater than 500 ms. Loss of motor phase or shorting contactor connection. Supply frequency outside limits upon initialization. For 60 Hz operation, the supply frequency must be between 56.4 and 63.6 Hz. For 50 Hz operation, the supply frequency must be between 47 and 52.5 Hz. Phase reversal may be selected to prevent operation if the supply phase rotation does not correspond to the specied rotation direction. The ATS46 controller also trips on overcurrent due to a short circuit at the controller, a shorted SCR, or a shorting contactor malfunction. Although the controller may detect these faults, the user must install an external means of automatically disconnecting the motor from the line supply. This external disconnect provides protection for the motor, driven machinery, and operating personnel.
CONTROLLER I/O CONFIGURATION
The ATS46 controller provides several inputs and outputs that can be adapted to a variety of functions. The controller is preset at the factory to meet the requirements of most applications. The functions of the inputs, outputs, and optional congurations are described below. One normally opened and one normally closed contact is supplied for indication of fault or control of an isolation contactor. In the default mode, R1 contacts change state if a fault is detected. The contacts are in their normal state upon application of control power. Once the self diagnostic check is completed, if no fault is found, the fault relay energizes. The fault contacts will change to their de-energized state if a fault condition is detected, or if control power is lost. If congured for control of an isolation contactor, the R1 contacts stay in their normal state until a run command is initiated. The R1 contacts then stay energized until a fault condition is detected or until deceleration is complete. This allows the user to coordinate an isolation contactor to disconnect the motor from the line under a fault condition or when the motor is not in use.
Faults/Iso Contactor Control Relays
End of Start-up Relay
A normally open relay is provided to allow for easy integration of a shorting contactor. The end of start-up relay closes once the motor has reached full speed and opens following a fault condition or after a stop command is initiated. Following a stop command, the end of start-up contact is used to drop out the shorting contactor so that deceleration control may be used if selected. If a shorting contactor is going to be used to bypass the SCRs after starting is complete, the shorting contactor must close within 500 msec of detection of full speed operation. If a shorting contactor is used, the end of start-up relay must be used to coordinate operation of the shorting contactor.
Two logic outputs compatible with PLC inputs are provided on the ATS46 controller. The factory preset for LO1 indicates a thermal pre-alarm. In this conguration, the logic output changes to state 1 when a motor thermal overload pre-alarm has been reached, and stays high until the thermal fault has cleared. When a pre-alarm condition exists, corrections should be made to the process to prevent an actual overload fault condition, which requires down time for motor cooling. The LO1 output may also be congured for motor power indication. In this conguration, the output changes to state 1 whenever the motor current is present. A second logic output, LO2, is provided to signal an overcurrent alarm. If overcurrent detection is not selected, LO2 is inactive.
Chapter 3Application and Protection Display of Motor Values
An analog output is provided that indicates motor status. The A1 output can be congured for 0-20 mA or 4-20 mA output. The analog output is factory preset to indicate motor current, but may be congured to indicate motor torque, thermal state, or power factor. The logic input is factory pre-set to force the controller to a freewheel stop. Alternate congurations include external fault, force to local control, control of cascading motors, and thermal overload reset. Force to Freewheel: Overrides controlled deceleration if selected. External Fault: Interrupts controller operation following an input from an external fault detection device. Local Control: If using the communications option (VW3-G46301), the logic input must be congured for local control. When congured for local control, activating the logic input is required to switch from remote to local operation. Control of Cascading Motors: When initiated, allows for control of several motors. Thermal Overload Reset: The logic input may be congured to require operator acknowledgment of a thermal overload condition. In this conguration, the logic input must be changed to state 1 after the thermal fault has cleared before the motor may be re-started. Fault Reset: The logic input may also be congured to require operator acknowledgement of all faults. In this conguration, the logic input must be changed to state 1 after a fault has cleared before the motor may be restarted.
DISPLAY OF MOTOR VALUES
The ATS46 controller provides a three-digit LCD display that can be set up to display the controller and motor characteristics, as described in Table 12.

Chapter 4Controller Setup and Operation Factory Presets
The ALTISTART 46 (ATS46) controller is factory preset, which, for many applications, allows operation without requiring adjustment. As shown in Figure 36, a switch is located behind the removable display module that can be toggled from standard duty to heavy duty application presets.
1 = Standard Duty 2 = Heavy Duty
Figure 36: Factory Preset Selector Switch The ATS46 controller is factory preset to standard duty operation. To switch the factory presets to heavy duty applications, remove the control module and change the selector switch to position 2, as shown in Figure 36 (inset). For the change to take effect, control power must be cycled after adjusting the selector switch. The following factory presets change when adjusting the selector switch from position 1 to position 2:
Acceleration Ramp Current Limit Overload Protection Ac Ilt thp
Standard Duty Preset
10 seconds 300% Class 10
Heavy Duty Preset
15 seconds 350% Class 20
Table 20 on page 65 lists the factory preset for the motor nominal current, In, and corresponding motor combinations for standard duty and heavy duty presets. If the motor full load amp rating is not within 95 and 105% of the ATS46 controller factory preset value, or if motor has a 1.0 service factor, adjust the controller for optimal motor protection and performance. Tables 16 and 17 provide the Level 1, 2, and 3 factory presets for the other parameters available.
NOTE: If purchasing a Class 8636, 8638 or 8639 Enclosed ALTISTART, refer to the supplemental instruction bulletin provided. Modications have been made to the factory settings listed above for some enclosed products to more closely match the motor full load amp ratings at the specied motor voltage. In addition, if an input contactor is provided, the R1 relay has been re-set for isolation contactor control.
A keypad is provided to allow digital set up of the controller and real-time indication of motor performance. The keypad has three seven-segment display characters, one program LED, and four pushbuttons for programming the controller, as shown in Figure 37. The keypad may be removed after loosening the holding screw, and can be removed while the controller is switched on. The keypad does not have to be in place in order to operate the controller.

Figure 39: Displaying the Monitoring Parameters Control Parameters Control parameters consist of conguration and adjustment parameters. Conguration parameters indicate the type of control or on/off selections and can only be modied when the controller is in a ready status. Adjustment parameters are functions that have an adjustment range or level, and can be modied at any time in setup mode. For example, the type of deceleration control is a conguration parameter and cannot be changed once the motor is operating. However, the deceleration ramp time is an adjustment parameter and may be adjusted at any time in setup mode. If adjusted prior to a stop command, the deceleration time adjusts to the new setting at the next stop command.

The nominal motor current is factory set according to the controller rating and position of the switch beneath the keypad. If the factory setting is not between 95 and 105% of the motor FLA rating, adjust the In to obtain optimal performance and thermal protection. See Setting the Motor Current on page 52. Sets the maximum current drawn during acceleration. Setting the Current Limit on page 53. See

Adjusts the acceleration torque ramp. Adjusting the Acc setting changes the slope of the torque reference, providing a more or less gradual start. Selects the stopping control method. Selecting -F-, -d- or -b- indicates freewheel, deceleration ramp or braking. In freewheel mode (-F-), all voltage is removed from the motor following a STOP command. The motor coasts to a stop with the deceleration time dictated by the inertia and resistive torque of the driven load. If deceleration ramping (-d-) is selected, the user may adjust the ramp time and voltage at which the ramp ends. dEc is used to adjust the time to change from measured torque to zero torque. If deceleration ramping (-d-) is selected, the torque level at which the deceleration ramp ends may be adjusted. Once the torque reaches the threshold value, the controller changes to freewheel mode and the motor coasts to a stop. If the torque is below the threshold setting when a stop command is given, controlled deceleration is not activated and the controller changes to freewheel stop. If braking (-b-) is selected, adjusts the braking level used during InTele braking. Note that the duration of the braking application is dependent on the motor loading. If torque is too low on starting due to dry friction, stiff mechanism or high inertia, the boost function provides increased torque to initiate motor shaft rotation. Voltage is applied for 5 mains cycles during boost. Adjusts the initial torque upon energization. The initial torque setting and the slope indicated by the Acc dene the motor starting performance. The starting performance may be optimized by adjusting the initial torque setting without modifying the slope of the ramp. Limits the peak torque provided by the motor. Primarily used to limit acceleration of high inertia applications, the torque limit combines with the slope and initial torque settings to provide a customized torque prole. An underload threshold can be set to prevent damage to the driven machinery or process resulting from an underload condition (i.e., dry pump condition). The underload detection is only active during steady state operation. To prevent nuisance tripping, the underload condition must last for 4 seconds. If a short underload condition occurs and loading returns to a value 10% above the user-dened threshold, the underload detection is reset. Detection of continuous and brief underload conditions is shown in Figure 37 on page 43. Compares the motor acceleration time to the time set using tLS. If the time is exceeded, the controller changes to a fault state of stF. The thermal overload class can be adjusted to provide Class 2, 10, 10A, 15, 20, 25 or 30 overload protection as dened per IEC 947-4-2. The thermal overload protection may be turned off if external protection is provided. Refer to Figure 36 on page 42 and Figure 37 on page 43 for information about trip curves for motor starting.

If the supply does not correspond to the selection, the controller changes to fault state PIF. This function is only activated if a run request is issued. The following settings are available for assigning relay R1: rIF = fault relay rII = isolation relay (controls a line contactor) After a request to reset the motor thermal state, parameter rth returns to no.

Torque control (CLP) is automatically disabled when using SSt. Signals the operation of cascading motors. TCS ramp is inactive in this mode because the motor power does not match the controller rating. Indicates the operating time, in hours, since the last reset. Elapsed time includes starting, running and stopping time. May only be reset using one of the line communication options: VW3G46104 PC software or VW3G46301 PLC communication. The time after a STOP command in freewheel mode or after the end of ramp or braking before a new START command will be accepted.
Test on low power motor
Time before starting
The motor nominal current (In) is factory preset to the values listed in Table 16 on page 50. If the preset value is not within 95-105% of the motor nameplate current, or if using a 1.0 service factor motor, the In parameter should be adjusted as follows:
1.0 1.15 or 1.25
In = 0.96 x Nameplate Current In = 1.00 x Nameplate Current
For 1.15 or 1.25 service factor motors, the nominal current may be set as high as 104% of the nameplate current if required to prevent nuisance tripping.
MOTOR OVERHEATING Motor current draw above nameplate rating will result in motor temperature rise. Extended exposure to overcurrents will cause the motor to overheat resulting in thermal overload fault or equipment damage. The following conditions can cause excessive heating: Excessive duty cycle (more than 6 evenly spaced starts per hour) Excessive acceleration ramp due to high inertia loads High ambient temperature Check with the motor manufacturer for the motors suitability for operation on a solidstate reduced voltage controller congured for your application. Motor thermal sensors built into the motor windings and connected through the control logic may be required for motor protection. Specic application duty motors, such as explosion proof and submersible motors will require enhanced protection and special considerations in application. The motor manufacturer MUST be consulted when applying these motors. Failure to follow this instruction can result in injury or equipment damage.
The current limit is expressed as a percentage of the In setting and is adjustable from 150 to 700%. However, the maximum starting current is limited to 500% of the controller rated current. The peak amperage drawn using the current limit feature can be determined by the following formula: Ilt * (In / ICL) 500 For example, if the motor FLA equals the controller rated amps, the maximum current limit setting would be 500. If using a motor rated for 50% of the controller rating (the minimum setting), the current limit may be set as high as 700%.
Advanced Acceleration Ramp Adjustments
For constant torque or high performance applications, the performance of the ALTISTART 46 controller may be optimized by the following steps: 1. Measure load requirements: a. Set controller to monitor load torque (LTR). b. Start the motor with the factory default settings. c. Load the motor to the maximum continuous load torque for the application. d. Read the measured torque (LTR) for continuous duty (normal speed). e. Stop the motor. 2. Adjust the controller: a. Set the current limit (ILT) to the maximum setting to provide the maximum starting torque. b. Set the initial torque (tq0) and torque limit (tLI) to 120% of the measured load requirements. For example, if LTR = 50, set tq0 and tLI to 60. 3. Optimize the application: a. Issue a run command. If the motor starts, reduce the stator loss compensation (LSC) by 10. Repeat until the motor no longer starts then increase by 10. The application is then optimized to within 10%. b. If the motor does not start, increase the stator loss compensation (LSC) by 10. Repeat until the motor starts. The application is then optimized to within 10%.

Chapter 5Fault Management Introduction
The ALTISTART 46 (ATS46) controller provides state-of-the-art protection for the motor and controller and provides exibility and the ability to adapt to normal power disturbances. The following describes the diagnostics available on the ALTISTART 46 controller as well as how the controller will respond to the type of fault detected in manual and automatic restart modes. Finally, conditions which may have caused the fault condition and corrective actions for each fault code are given.
HAZARDOUS VOLTAGE Read and understand these procedures before servicing ATS46 controllers. Installation, adjustment, repair, and maintenance of these controllers must be performed by qualied personnel. Electrical shock will result in death or serious injury. Fault Relay Setup The ATS46 controller provides relay and logic output for fault indication. Both fault outputs can be congured to meet application requirements, which can then be set up to provide customized fault indication. The controller can also be set up for automatic restart. Refer to Chapter 3 for details on programming the controller. Logic output LO1 is factory preset to indicate a motor thermal pre-alarm, which may be congured to initiate a correction in the process prior to exceeding the thermal capacity of the motor. The LO1 logic output may also be congured to signal that the motor is running. Relay output R1 is congured by the user to provide detection of a fault only or control of an isolation contactor. A normally open and normally closed contact are provided to signal external devices. When in the factory default conguration, the R1 relay will energize following a successful self-diagnostic test and remain energized until a fault condition is detected. The R1 relay is in the de-energized state when control power is not applied and when a fault is detected. If congured for control of an isolation contactor, the R1 relays stay in the de-energized state until a start command is issued. Following a start command the R1 relays remain energized until deceleration is complete or until a fault is detected. If controlled deceleration is not selected, the R1 relays change state following a stop command. This provides automatic interruption of the line voltage following a fault and when the motor is not in use. Fault Display If a fault occurs during the operation of the ALTISTART controller, a fault code is displayed on the keypad indicating the starter status. The last ve faults that have occurred are stored in controller memory. To view the fault memory buffer, use the PC or PLC option. To view the controller settings while a fault code is displayed, press the DATA push-button until the programming menu is displayed. A red LED on the front of the controller also indicates a fault condition. Fault conditions are broken into three categories: internal, phase, and thermal. To restart the motor, the fault condition must be cleared and the controller must be reset. The method used to reset the controller depends on the type of fault detected and if automatic re-start is selected.
Chapter 5Fault Management Resetting the Controller
Fault Denitions
The ATS46 controller continuously monitors the motor and starter performance. If a fault is detected, the controller will interrupt motor operation and switch to a freewheel stop. After the fault has cleared, the steps required to restart the motor depend on the type of fault that was detected. The following is a guide for restarting following a fault condition: Cycle Control Power: Cycling control power resets the controller following any fault condition and is required for non-resettable faults. A new or maintained run command will restart the motor after control power is recycled if the fault has cleared. Manual Restart: The controller may be restarted by issuing a new run command after any resettable fault once the fault has cleared. Auto Restart: If selected, the controller will restart automatically only if a maintained run command is preset, when using two wire control. An automatic restart will only occur after specic faults have cleared. Following a Type 1 fault, the controller will restart once the fault has cleared. Following a Type 2 fault, the controller will attempt to restart the motor after 60 seconds. If the fault has not cleared after 6 successive attempts, the fault must then be reset by cycling control power. A manual restart is required following a Type 3 fault.
UNINTENDED EQUIPMENT ACTION Automatic restart can only be used for machines or installations that present no danger for personnel or equipment in the event of automatic restarting. Equipment operation must conform with national and local safety regulations. Failure to follow this instruction can result in death or serious injury. Table 18: Fault Denitions

If LI is congured for motor overload reset (Lit), operator acknowledgment of the overload condition is required. The overload must also be reset through the logic input after the fault has cleared before restarting the motor.
Chapter 5Fault Management Troubleshooting Faults
Resetting the controller once the fault has cleared may not correct the condition that caused the fault to occur. In addition, there are failure modes of this controller which may require an external device to ensure power is removed from the motor. Refer to Chapter 2 for proper installation guidelines.
MOTOR OVERHEATING Failure of the controller solid-state switches can cause single-phase operation of the motor. Use an isolation device consisting of either a circuit breaker equipped with a shunt trip coil or an electromagnetic contactor to open the line side of the controller. The isolation device must be capable of interrupting motor locked rotor current. Connect the Fault relay of the ALTISTART controller to open the isolation device in the event of a controller fault. Failure to follow this instruction can result in injury or equipment damage.
The following guidelines provide general troubleshooting assistance based on the fault code displayed on the keypad. If the controller is still inoperative after checking the motor and system status as recommended, consult your local Square D sales ofce. Phase Fault Fault Code: PhF Possible Cause: Mains supply failure greater than 500 ms when run command is present. Motor current draw less than 10% of the nominal starter rating. SCR failure Power factor greater than 95% lagging
Corrective Action: Verify that supply voltage is present on L1-L2-L3 terminals. If an isolation contactor is used, it must close within 200 ms of a run command. Check for open phases including: Blown fuses Open or loose power connections SCR failure - not resettable via control logic If the fault is detected after completion of the acceleration ramp, ensure that the proper connection of the shorting contactor if used. The output of the shorting contactor must be connected to terminals A2-B2-C2, and must close within 200 msec after the motor is up to speed. Motor current draw must be more than 10% of the controller rating while running without a shorting contactor. Frequency Fault Fault Code: FrF Possible Cause: Mains supply frequency outside acceptable limits. Corrective Action: Check that the frequency is between 60 Hz +/- 3.6 Hz (56.4 Hz to 63.6 Hz) 50 Hz +/- 2.5 Hz (47.5 Hz to 52.5 Hz)
Supply Fault with Run Command Present
Fault Code: USF Possible Cause: Voltage is not present at L1-L2-L3 terminals when a run command is present. Corrective Action: Verify that supply voltage is present on L1-L2-L3 terminals. If an isolation contactor is used, it must close within 200 ms of a run command. Check for open phases including: Blown fuses Open or loose power connections SCR failure - not resettable via control logic
Motor Thermal Fault
Fault Code: OLF Possible Cause: Motor overload Excessive starting or stopping time or frequency Motor operating current incorrectly set Corrective Action: Inspect motor and driven equipment for problems, including: locked shaft mechanical overload Check the dynamics of the load and driven machine for suitability with reduced voltage starting. Check the duty cycle for the selected thermal overload class. Check the In setting.
Starter Thermal Fault
Fault Code: OhF Possible Cause: Duty cycle above the thermal capabilities of the controller. Ambient temperature too high. Poor air circulation/lack of ventilation. Corrective Action: Reduce duty cycle demand on controller. Provide additional cooling around controller. Reduce ambient temperature requirements.
Fault Code: LrF Possible Cause: Current greater than 500% of the motor FLA setting is detected for more than 200 ms during steady state operation. Corrective Action: Check motor for locked shaft. Remove obstruction prior to restarting.
Motor Underload Fault
Fault Code: ULF Only applicable if ULL is programmed. ULL is factory pre-set to NO. Possible Cause: Load level below the set ULL level. Damage to drive train (broken belts, shafts, etc.). Pump running dry or with no ow. Corrective Action: Check the application for changes that may cause performance outside acceptable limits Change in process, loading, or operation Mechanical system inspection Incident in pump hydraulic circuit
Max Start Time Exceeded
Fault Code: StF Only applicable if tLS is programmed. tLS is factory pre-set to NO. Possible Cause: Start time exceeds tLS maximum start time setting. Change in process, loading or operation. Corrective Action: Check the application for changes that may cause performance outside acceptable limits Mechanism wear Mechanical incident
Fault Code: EtF Only applicable if LI is programmed to detect external fault LIE. LI is factory pre-set to NO. Possible Cause: External fault detected and signaled to the logic input. Corrective Action: Check external fault detection mechanism.
Internal Serial Link Fault
Fault Code: SLF Possible Cause: Bad connection of the keypad or serial link option module. Corrective Action: Check option module connection Replace option module
Fault Code: OcF Possible Cause: High impedance short circuit at the output of the controller Internal short circuit Improper sequence of shorting contactor Corrective Action: Remove power from controller and check for: Damage to power cables and/or motor insulation Damage to thyristors Damage to shorting contactor/contactor stuck in closed position

Chapter 6Servicing the Controller Introduction
For the protection of personnel and equipment, a qualied maintenance person must perform the procedures detailed in this manual. The maintenance person should: Read, interpret, and follow instructions and precautions in this manual and the other manuals referenced. Use the tools listed on page 65 of this manual in a safe and technically correct manner. Perform troubleshooting and parts replacement procedures while following the safety procedures recommended in ANSI/NFPA 70E. Be trained on the operation and fundamentals of AC controllers and systems and be familiar with the associated hazards. Review the sections below for personnel and equipment protection precautions before performing parts replacement procedures.
HAZARDOUS VOLTAGE Read and understand this section before maintaining or servicing the ALTISTART 46 controller. Only qualified personnel should install, adjust, service, and maintain these controllers. Conrm that controller has been correctly selected, installed, and applied before performing any service or maintenance. Verify that all controller overcurrent protective devices, conductors, enclosures, and other circuit elements have been correctly selected for application and that controller is properly grounded in accordance with equipment instruction bulletin recommendations and applicable code requirements. Many parts in this controller, including printed circuit boards, operate at line voltage. DO NOT TOUCH. Use personal protective equipment and follow precautions and measurement procedures referenced in this bulletin when making any measurements on energized equipment. Use instruments and insulated tools approved for job. Install all covers before applying power or starting and stopping controller. Observe and follow all applicable lock-out and tag-out procedures for specic installation. Electrical shock will result in death or serious injury.
PERSONNEL PROTECTION PRECAUTIONS
ATS46 controllers contain components that can be potentially hazardous to maintenance personnel. Semiconductor devices can exhibit hazardous leakage currents in the off state. Personnel performing parts replacement should be thoroughly familiar with ANSI/NFPA 70E. Follow these safety measures:
1. Verify that the equipment has been installed and applied in a manner that is consistent with the information in the equipment instruction manual, applicable code requirements, and regulations. 2. Coordinate all parts replacement procedures with the operations manager of the facility. 3. Ensure that the controlled equipment is disconnected from the controller or that access to it is prohibited. 4. Read all precautions in this manual that relate to the procedure being followed. 5. Make sure you are familiar with the tools and instruments required for the specic procedures described in this chapter. 6. Ensure that you have proper body protection: clothing, eye protection, helmet, and other safety gear. 7. Ensure that electrical equipment surrounding the controller is either de-energized or isolated in such a way that maintenance personnel are not subject to electrical shock.
Chapter 6Servicing the Controller Standards
8. Ensure that all power sources feeding the controller are de-energized and locked/ tagged out before opening the controller door or performing parts replacement procedures. Never assume the power is off. Always check for voltage with a properly rated voltage sensing device. 9. Inspect the controller bonding and ground system and ensure that the controller is properly grounded per the applicable codes and recommendations in this instruction bulletin. ATS46 controllers use some specialized components to achieve rated performance during operation. Some of the components in the controller require special attention. For example, the SCRs require specic torque settings for proper operation. When replacing parts, follow the guidelines on page 2 and those listed throughout the book. Be sure to install thermal grease when mounting components which use the heatsink for dissipating heat (i.e., power semiconductor devices). Always torque semiconductor components using the method described in the applicable parts replacement procedure. If the controller is removed from its permanent mounting location while replacing parts, ensure that it is properly secured in an upright position before re-energizing. During maintenance, do not block, impede, or otherwise diminish cooling air ow over or through the controller. When installing a new control module, the controller may require programming if the factory default settings are not suitable for the specic application. Avoid touching exposed conductors and component leads with skin or clothing.

Chapter 6Servicing the Controller Replacing the Control Module
EQUIPMENT DAMAGE ALTISTART 46 controllers use metric fasteners. Do not substitute SAE or alternate fasteners. Failure to follow this instruction can result in equipment damage.
ATS46 controllers use metric fasteners and require the use of metric driver tools. Do not substitute SAE or any alternate fastener. Substitution may result in damage to threaded inserts, breakage of components and subassemblies, overheated electrical connections due to improper torque levels, and general structural failure. All procedures in this section must be performed with power removed from the controller.
To gain access to the power section or for replacement on all ATS46 models, remove the control module.
To remove the control module, follow these steps:
1. Using a at blade or Torx screw driver, remove the four screws from the front of the control module. 2. Using a connector extractor, disconnect the nine electrical connectors from the back of the module. While the connectors and module are labeled, note the label and location of each connector. Figure 45 shows a diagram of the module and its connector labels.

Figure 45: Replacing the Control Module
To replace the control module, follow these steps:
1. Install the electrical connections. Push all connectors so that they are rmly in place. 2. Mount the control module to the power section. Carefully secure all wires in the controller to prevent damage to the wire or loosening of the connections. 3. Retighten the four holding screws.
NOTES: When the control module is damaged, the entire module must be replaced. Any attempt to access, repair, or inspect the control modules circuit boards voids the product warranty. When replacing the control module, note that the replacement control module does not include the operator interface (keypad or communications module). The user must purchase a replacement operator interface separately.
POWER SECTION REPAIR ATS46D17 TO C32 CONTROLLERS
The control module must be removed to repair the components in the power section. The ATS 46 product line consists of ve frame sizes which share common power section design. The replacement process for the power components is similar for units within a frame size. For units rated 17 through 320 amps, remove the control module and protective housing to access the power components directly. These items are replaceable in the power section of the 17 through 320 A models (D17 to C32): SCRs Current measurement board Filter card Control power transformer Fan and thermal switches (on models rated 72 A and above) Figures 46, 47, and 48 show available replacement parts.

When an SCR fails, the ATS46 controller will not attempt to start the motor. Upon a start command, a device with a failed SCR immediately shows a phase fault or internal fault code.
HAZARDOUS VOLTAGE Before checking thyristors: Disconnect all power. Place a DO NOT TURN ON label on the controller disconnect. Lock disconnect in open position. Electrical shock will result in death or serious injury.
To verify the damaged pole and determine how many poles should be replaced, perform the following tests. For D17 through C32 controllers, the SCR modules can be directly accessed.
NOTE: The ATS46C32N controllers use two SCRs per phase. All other models use a dual pack SCR that requires one module per phase.
1. With the equipment switched off, isolate the starter by disconnecting the power terminals. 2. Remove line power from controller. Using a continuity meter, check the thyristors in pairs. Figure 49 illustrates this process, phase by phase, between terminals 1L12T1, 3L2-4T2, 5L3-6T3. If continuity is indicated, at least one of the thyristors is short-circuited.
Open - SCR not failed Closed - SCR failed
Figure 49: Checking Thyristors
To remove the SCR module, follow these steps:
1. Disconnect all electrical connections to the SCR module. Note the color and connection of each lead. Remove only one SCR module at a time so that the other modules may be used as a reference when replacing the SCR module. 2. Remove the power connections: For D17 through C14 controllers: Use a hex key to remove the power straps which connect the SCRs to the line and load terminals. For C17 through C32 controllers, rst remove the lter card (see page 10). Then remove the bus bar connections using a 10 mm socket wrench (two bolts per phase). 3. Using an Allen wrench, remove the four screws at the base of the SCR module which hold the SCR to the heatsink.
To replace the SCR module, follow these steps:
1. Apply a thin coat of thermal grease (e.g., Alcoa #2EJC or equivalent) between the heatsink and SCR for better heat transfer.
NOTE: Do not allow grease to go into the threaded hole.
2. Install the new SCR module, applying the proper torque to the screws holding the SCR to the heatsink and to the bolts connecting the power straps or bus bar to the SCR. Table 20 lists the proper tightening torque for the SCR connections. 3. Reconnect electrical leads to the SCR module in their original positions. Table 20: Tightening Torques

When replacing SCRs damaged from exposure to excessive current or voltage (e.g., short circuit or lightning strike), it is good practice to replace the current measurement board and lter card for the replaced poles.
FIlter Card Replacement
For D17 through C14 controllers, there is one lter card per unit mounted below the L1/ L2/L3 connections. For C17 through C32 controllers, there are three lter cardsone mounted to the bus bar on each phase.
To replace the lter card on D47 through C14 controllers, follow these steps:
1. Disconnect electrical connections from the board. Note the position and color of each wire for reassembly. 2. Disconnect power straps to SCRs as needed to access lter card. 3. Using a at blade screwdriver, remove the lter card mounting screws. Removing the bus wiring may facilitate the removal of the lter card. To access the lter card (in D47 through C14 controllers only), follow these steps: 1. Take out the top two front cover screws. See Figure 47 on page 68. 2. Take out the four screws from the bottom cover of the controller. 3. Disconnect T1, T2, and T3 from SCR. 4. Pull the bottom plastic end cap out. 5. Slide side panels down. 6. Remove the lter card. 7. Use a magnetic screwdriver to reinsert screws. To reinstall the lter card, reverse steps 1 to 5. Retighten the housing screws and power connections.
To replace the lter card on C17 through C32 controllers, follow these steps:
1. 2. 3. 4. Remove electrical connections for the card to be replaced. Using a Torx screwdriver, remove the mounting screw. Remove the lter card. To reinstall a new lter card, reverse steps 1 through 3.
To remove the current measurement board:
1. For D47 through C32 controllers, disconnect jumpers J13,J14, and J15 from the current measurement board. See Figure 50 on page 70. 2. Using a Torx screwdriver, loosen and remove the holding screws on the current measurement board. 3. On D17 through D38 controllers, the current transformers are mounted directly on the current measurement board. To remove the board, the three bus wires from the SCRs have to be disconnected and pulled out from the current transformer.
NOTE: To remove the bus wire from the current transformer, it may be necessary to remove the heat shrink from the terminal of the bus wire. Replace heat shrink upon re-installation. 4. Remove measurement board from power section; note connections for reassembly.
Thermal Switch and Fan Replacement On ATS46D75 through C32N controllers, there are two thermal switches. One controls the operation of the cooling fan, and the other is an alarm for controller thermal protection. The output of the heatsink thermal switch is fed to the current measurement board. The output of the fan control is in series with the fan and control power transformer. The cooling fans cycle on when the temperature of the heatsink exceeds 50 C. If the cooling fan does not turn on and the temperature exceeds 50 C, the thermal switch, the fan, or both may need to be replaced. The fans operate on 230 VAC single phase power. Use an external power supply, if desired, to test fan operation.
To replace a thermal switch, follow these steps:
1. Disconnect the two electrical connections from the output of the switch. 2. Using a Torx or at blade screwdriver, remove the two holding screws. It may be necessary to remove some of the SCR power connections to access the thermal switch. 3. Replace the thermal switch with the appropriate rated switch. The fan thermal switch should be rated for 50 C, whereas the heatsink switch is rated for 95 C or 105 C, depending on the controller size.
To replace the fan on D75 through C14 controllers, follow these steps:
1. Turn the unit with the heatsink facing up (i.e., access the fan from the back of the unit). 2. Remove the two electrical connections. 3. Remove the two holding screws. 4. To install the replacement fan, reverse steps 1 through 3.
To replace the fan on C17 through C32 controllers, follow these steps:
1. Remove the fan cover by removing the two cover screws. 2. Remove the six screws from the fan mounting plate. 3. Disconnect the fan power supply wires from the control power transformer (White) and from the thermal switch (Red). See Figure 51. 4. Remove the fan assembly. 5. To reinstall the replacement fan, reverse steps 1 through 4. Use caution when installing the fan to prevent damage to the wires.

Figure 51: Fan Mounting Plate Control Power Transformer (CPT) Replacement The control power transformer (CPT) provides the power to the control module and fan (if supplied). To replace the CPT, the user must have access to the fan connections. Refer to Thermal Switch and Fan Replacement on page 71 to service the fan assembly.
To replace the CPT, follow these steps:
1. Disconnect the four colored transformer supply wires from the terminal block beneath the control power connections. See Figure 57 on page 76. 2. For D72 through C32 controllers, disconnect the two wires that supply the fan power. For C17 through C32 controllers, pull the fan power wires through the fan and controller housing one at a time. 3. Remove the four transformer mounting screws attaching the transformer to the power section base. 4. Remove the CPT. 5. To install a replacement CPT, reverse steps 1 through 4. See Figure 57: Note the proper connections.

POWER SECTION REPAIR ATS46C41N TO M12 CONTROLLERS
Some replacement parts on models ATS46C41 to M12N can only be accessed after removing other items in the power section. Make a record of the wire connections and the order and location of all components before removing them from the power section. The following list contains replaceable items in the power section of the 410 through 1200 A models: Control module / Keypad SCR power pole assemblies Firing interface board Current measurement board Filter card Control power transformer Fan and thermal switches
Refer to Figure 53 to identify the available replacement parts. Table 19 on page 66 lists catalog numbers for each item. The instructions for replacing the control module, control power transformer, thermal switches, and fan are the same as for the ATS46C17 through C32N controllers described on pages 66 through 70.
Power Poles Firing Board
Figure 53: ATS46C41, C48, C59, C66, C79, M10, M12 SCR Power Pole Assembly The SCR power pole assembly consists of the power pole, the ring interface board, and two thermal switches for ATS46C41 through M12N controllers. The power pole consists of two SCRs within a heatsink. The heatsink is tightened to provide balanced heat and current transfer within the assembly. The power pole, interface board, and thermal switches are available as individual parts. Pre-mounted thermal switches are provided with the replacement power pole.
NOTE: SCRs are not available for individual replacement. Replacement of a single SCR through disassembly of the power pole will void the product warranty.
The ATS46C41 through M12 controllers use a ring interface board. Each SCR pole requires one interface board. Replace the board if there is visible damage to any of the components following an SCR failure. The replacement power pole assembly does not include an interface board. Reuse the original interface board (unless it is damaged) or order a replacement interface board.
Refer to page 68 for SCR testing information. The ATS46C79 through M12 controllers use two SCR power poles connected in parallel. If an SCR in either pole is shorted, replace both poles in the SCR assembly. To replace the SCR package, interface board, or thermal switches, remove the entire power pole assembly. Removal allows easier access to the individual components. Note the location of each wire as you remove the assembly. The interconnections between the SCR pole and ring interface board are not labeled.
To remove the power pole assembly from the controller chassis, follow these steps:
1. Remove the control module as described on page 67. 2. Either rotate the control module mounting panel or remove it. Either action allows access to the SCR poles, current measurement board, and control power transformer. 3. Disconnect the jumper to the interface card from the current measurement board. The label designation, from J4 to J9, depends on which pole the jumper connects to. 4. To remove the SCR pole assembly, disconnect the wires and remove the bolts indicated in Figure 54. Use a 10 mm wrench to remove the bolts. 5. Cut wire ties from the power pole assembly to the insulating wall. 6. Pull the SCR pole assembly from the controller chassis using the handle on the mounting bracket (C in Figure 54) and the free end of the lower braided cable.

To replace the power pole assembly on the controller chassis, follow these steps:
1. If replacing only the thermal switch or interface board, re-assemble the components to complete the power pole assembly. Complete this step before mounting the pole back in the controller chassis. Skip to step 3. 2. If replacing the SCR pole, remove the braided cables and standoffs. Use these in the new pole assembly. When replacing the braided cables, make sure cables are ush with the top side of the channel. Otherwise, proper conduction may not occur. Refer to Figure 56 for assembly of the cable to the channel. 3. Replace the red wire that is attached to the mounting bracket of the replacement pole. Re-tighten screw to maintain proper alignment of bracket. 4. Using the free end of the lower braided cable and the mounting bracket handle, replace the pole in the controller chassis. 5. Replace the removed wire from the pole assembly. Tighten the following to 80 lb-in (9 Nm): all 10 mm bolts holding the power pole assembly to the chassis; all connections to the bus bar. 6. Replace the jumper from the current measure board (see Figure 57 on page 76). Connect the four wires to the terminal block (see Figure 54 on page 74). 7. For C79 through M12 controllers: tighten to 40 Nm all bolts that connect the poles in parallel.

Current Measurement Board Replacement
The current measurement board, located behind the control mounting bracket on the angled part of the controller body, takes input from the current transformers; scales it; and provides the control module with motor current information for the control algorithms. For controllers with ratings of 410 A or higher, the current measurement board includes the gate drivers that higher rated SCRs require. If the current measurement board is damaged, acceleration or deceleration will not occur properly. To verify whether the current measurement board is working properly, compare the current display on the keypad to actual measured current. Typical causes of measurement board damage include exposure to a short circuit, excessive current ow, or improper shorting contactor sequencing. Replace the measurement board when replacing SCRs that are damaged by short circuit or lightning strike.

To replace the current measurement board, follow these steps:
1. Mount the board to the controller. Tighten the holding screws. 2. Reconnect all jumpers to the measurement board. 3. If plugs were removed, reconnect plugs on the end of the wires opposite the control module and SCR poles.
NOTE: The power section of the ATS46C79 through M12 controllers uses two power sections connected in parallel. The replacement instructions are the same for the C79 to M12 controllers except for pole connections. Figure 53 on page 73 shows pole connections for the C41 through M12N.
Thermal Switch Replacement The thermal switches from each pole are connected in series for operation of the fan and indication of heatsink over temperature. When replacing the thermal switch, note the location of the existing switch connection to the terminal block. This connection, on the pole assembly, is critical to proper operation of the fan and thermal alarm. On the ATS46C41 through M12 controllers, there are thermal switches for fan control and detection of the heatsink temperature on each power pole assembly. The SCR power poles must be removed to gain access to the thermal switches. Fan Replacement Use the same fan replacement in the ATS46C41 through M12 controllers as for the ATS46C14 through C30 controllers. Refer to page 77 for fan replacement instructions. On C79 through M12 controllers, each fan operates independently, based on the left and right side temperature. Control power transformer replacement for ATS46C41 through M12 controllers is the same as for ATS46C17 through C32 controllers. Refer to page 72 for CPT replacement instructions.
