Introduction & approvals

2 Introduction & approvals
Vibration Module is part of the Elmodis system for monitoring machines driven by induction
electric motors. The Vibration Module is an extension to the system, in which the Electro Moduleis the basic module. The purpose of the Vibration Module is to read and preprocess the data
coming from the vibration sensors. The signals from the vibration sensors are sampled at afrequency of 32 kHz. In order to synchronize the electrical measurements with the vibration
measurements, the module is equipped with an additional phase marker input installed on themachine shaft. This allows a spectral analysis of the signal over a wide frequency range and thedetection of anomalies in the vibration waveform related to a specific angular position of the
shaft. Communication between the Electro and Vibration modules is via Ethernet.

2.1 Basic features• Supports up to four vibration sensors• Support for IEPE (Integrated Electronic Piezoelectric) sensors• Temperature measurement from vibration sensors with integrated temperature sensor• Sensor signal sampling with frequency of 32kHz• Ethernet interface for communication with the Internet and other SDMS modules• 24 VDC power supply• Mounting on DIN TS35 rail

4.2 External wiring• Material of power and measuring cables: copper.
• Minimum working temperature of external wires: 75°C.
• Minimum working voltage of wires: 300 V.
• Before connecting the wires to the plugs, they should be properly prepared by crimping thesleeve endings on them.
• During installation, follow the instructions regarding cable cross sections and types.

4.3 Installation requirements• Accident prevention regulations must be observed during installation, startup,
maintenance and repair work.
• Emergency stop devices and functions must be effective - see the relevant standards (e.g.
DIN EN 418).
• To eliminate potential sources of interference, the installation must be carried out
according to EMC guidelines.
• The norms, standards, guidelines and local regulations in force at the time of installationmust be observed.
• The inputs are not insulated, so all sensors must be installed in such a way as to ensure
adequate isolation from components / circuits at hazardous potentials.
• At least simple drawing, showing connections on the terminal in the cabinet where thedevices are connected, should be prepared.

7.1.2 Installation of the electrical part
• The vibration sensor can be connected directly to the SDMS-VMS-E module using theoriginal prefabricated cable, which is terminated on one side with a plug matching thesensor (on the vibration sensor side).
• Depending on the vibration sensor, this may be a cable with an M12 plug (plug connectedto the vibration sensor). There are also vibration sensors with other connector designs,
such as MIL, in which case you must use a prefabricated cable with the appropriate
connector.
• The vibration sensor can also be connected by means of a shielded cable laid in the placeof installation, after fitting a suitable plug on it, e.g. M12 (or other suitable for the sensor),which will be connected to the vibration sensor (use a 2x2x0.5mm² cable - twisted pairs inthe shield).
• If the distance between the SDMS-VMS-E module and the sensor is longer than the lengthof the prefabricated sensor cable (standard length is 5m, but other designs are available), it
is necessary to make the cable yourself - use a plug suitable for the sensor and connect it
to a properly made cable (see the description of cable preparation later in this manual).
• If the distance between the vibration sensor and the SDMS-VMS-E module is longer thanthe length of the prefabricated cable or the cable connected to the sensor, you can also
use a patch box equipped with a suitable terminal to connect the prefabricated sensor
cable on one side and the cable to the SDMS-VMS-E module on the other side. The samecan be done if you want to group cables from up to 4 sensors in one place to run thesignals through a single patch cable to the SDMS-VMS-E module.
• The maximum recommended distance for connecting the sensor is 200 meters. If you
wish to mount the sensor over a longer distance, please contact Elmodis.

Connection preparation on the M12 connector side
The vibration sensor is connected using an M12 IEC60947-5-2 type plug (or other - depending on
the sensor version).

Fig 15. Pin layout on M12 IEC60947-5-2 type connector in the sensor

Preparing the cable for the plug:• Place the cable gland, nut, and plug housing on the cable.
• Remove the outer insulation of the cable over a distance of 30 mm.
• Cut the shield.
• If you are using a 4-wire cable, cut the yellow wire.
• Place the shrinking sleeve over the 30 mm length of the cable and shrink it so that the cut
shield does not come into contact with the connector.
• Put the crimp end sleeves (suitable for the wire diameter and terminals in the plug) on thewires of the cable, and crimp them.
• Screw the wires to the corresponding pins according to the table at the beginning of thechapter (according to the sensor/connector type).

Verification
Verification of site and installation environment
Before installing the sensor, visually verify that the installation site is not located near equipmentthat may generate electrical and magnetic interference. Check that the machine on which thesensor is mounted is properly grounded.
Verification of cable and connections
Before laying the cable on the object with the plugs installed:• Check for short circuits (between conductors and to shield - all combinations).
• Check continuity of conductors and shield.
• If necessary, use an insulation resistance tester.
After the cable has been laid, repeat the above steps to check if the cable has not been damaged
during installation.
Verification of the correct state of the inputs based on the module's LEDs indication
If the cable to the sensor is correct, the sensor is operational and the input of the SDMS-VMS-E
measuring module is configured, the green LED on the module's front panel (at markings [1] - [4])will light up (it may possibly blink if measurements are currently being performed on the channel).

If this happens:• Check the wiring of the 4-pin module plug.
• Check the connection of the plug to the vibration sensor.
• Measure voltage on terminals (1-2) of the 4-pin connector of the respective channel on the
SDMS-VMS-E module (as shown in the diagram below).

ResultMeasured voltage
20-22VDC

If the measured voltage on terminals (1-2) of the module 4-pin connector is in the range of
20-22VDC, it means that the sensor is disconnected or there is a break in the measuring circuit
caused by the fact that:• The measurement cable is faulty.
• Wrong connection of the leads in the plug for the vibration sensor.
• The connector to the vibration sensor is not screwed on firmly.
• The vibration sensor is defective.
Accordingly, you should:
1. Check the continuity of the measuring circuit by disconnecting the 4-pin plug from thegiven channel on the SDMS-VMS-E module and disconnecting the connector from thesensor - check the continuity of individual wires between the module's 4-pin plug and thesensor connector with a meter.
2. If the continuity of the wires is correct, connect the 4-pin connector to the SDMS-VMS-E
module and take the measurements according to the table below.

If, after measuring voltages and currents (according to what is shown in the table above) andafter tightening the cable plug to the vibration sensor, there are no green diodes on the module fora given channel but the red one is on - this may suggest that the vibration sensor is damaged.

 Problem: Shorted vibration sensor
If the vibration sensor connected to the module is short-circuited, the module signals the input
short-circuit status by blinking the red LED at the corresponding input of the SDMS-VMS-E
module.

Therefore, you should:
Check the measuring circuit by unplugging the 4-pin plug from the respective channel on the
SDMS-VMS-E module and disconnecting the plug on the sensor - check the individual wires
between each other with a meter. If after checking it turns out that the measuring cable is good(there are no short circuits between the wires) connect the 4-pin plug to the SDMS-VMS-E moduleand the connector to the vibration sensor - if a short circuit is still indicated on the module, thevibration sensor is probably defective and should be replaced.

correctly, in standby modeand still there are no temperature measurements then you should measure the voltage between
terminals 2-3 of the plug on the SDMS-VMS-E module of the given channel. The voltage value
between terminals 2-3 is directly proportional to the temperature that the vibration sensor
measures - the factor 10 mV/°C gives us, for example, 200mV on the terminals at 20°C and
300mV at 30°C.

Electrical installation of sensors
Inductive sensor (E2B-M18KN16-WP-C2-2M)• The cable shield, if any, should be connected to GND.
• The cable connecting the sensor with the device should be as short as possible.
• The cable connecting the sensor with the device must be led away from electromagnetic
interference and power supply cables (especially if an inverter is used).

Fig 18. Mating the plug for the inductive sensor

1. Twist the shield tightly and crimp it into the sleeve along with the GND wire.
2. Put heat shrink tubing over the wire.
3. Hide the fourth wire of the inductive sensor (if any) under the heat-shrinkable tube.
4. We recommend the following cable for shrinking: LAPP CABEL: Li2YCY-TP; 2x2x0.34mm2.

Mechanical installation of sensors
Installation example for inductive sensor

Fig 20. Mounting the inductive sensor

1. Use the recommended sensor or a sensor that meets the given parameters.
2. The sensor is to be mounted on a structure, on a firmly fixed element. Mounting must be
resistant to vibrations and nuts must be secured against spontaneous unscrewing (e.g. byusing serrated washers or anaerobic glue).
3. If the sensor does not have a potentiometer for sensitivity adjustment, adjust its range of
operation by setting the distance X, i.e. the tripping distance of the sensor.
4. The sensor activator must be a metal element. Its width should be from 5 to 20% of thecircumference of the element on which the speed is measured. It is recommended to fix
the activator mechanically, however, due to the difficulty of making it, it is permissible to fix
it chemically. For small drives where the mass of the actuator is significant and may cause
unbalance it is recommended to use an optical sensor.

Example of optical sensor mounting

Fig 21. Mounting the optical sensor

1. Use the recommended sensor or a sensor that meets the specified parameters.
2. Adjustment knob for sensor sensitivity. Adjust the sensor according to the sensitivity
adjustment procedure described below.
3. Mount the sensor to a structure, firmly attached. The mounting must be resistant tovibrations and the nuts must be secured against spontaneous unscrewing (e.g. by using
serrated washers or anaerobic glue). It is recommended that the cover should also act asa barrier to light, particularly from discharge lamps, to avoid interference.
4. The reflector should be glued to a clean surface and its width should be from 5 to 20% of
the circumference of the element on which the speed is measured. It is recommended touse a special self-adhesive reflective tape for optical sensors.
Procedure for adjusting sensor sensitivity• Mount the sensor in the target position.
• Set the sensitivity to the lowest.
• In the case of the E3FB-DN22 sensor, this is the extreme left position of thepotentiometer. Both LEDs (orange and green) should be lit.
• Position the shaft (or other rotating element on which a marker is placed) so that themarker is within the range of the sensor.

Input signals• Gradually increase the sensitivity until the sensor output changes.
• For the E3FB-DN22 this is indicated by the green LED only.
• Experimentally verify the change of state with simultaneous rotation of the shaft (or otherelement on which the marker is placed). The state should be:• high, when the marker is within the range of the sensor• low, when the marker is outside the range of the sensor
Changes in the sensor's output signal should be visible only when the shaft rotates and when amarker "appears" in the sensor's range or "disappears" from it. So there should be exactly twochanges per revolution.
For the E3FB-DN22, watch the LEDs while turning the shaft very slowly. When the marker is inrange only the green LED should be lit. On the contrary, both should be lit. In the transient state,
the diodes may go out for a while.
