1. Installation Precautions
CautionThis instrument is intended to be used under the following environmental conditions(IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 ) that does notchange rapidly, and no icing• An ambient non-condensing humidity of 35 to 85 %RH• No large capacity electromagnetic switches or cables through which large current is flowing• No water, oil or chemicals or where the vapors of these substances can come into direct contact withthe unit• Please note that the ambient temperature of this unit – not the ambient temperature of the control panel– must not exceed 50 (122 ) if mounted through the face of a control panel. Otherwise the life ofelectronic components (especially electrolytic capacitors) may be shortened.
Note: Avoid setting this instrument directly on or near flammable material even though the case ofthis instrument is made of flame-resistant resin.

2. Wiring Precautions
Caution• Do not leave wire remnants in the instrument, as they could cause a fire or malfunction.
• Use the solderless terminal with an insulation sleeve in which the M3 screw fits when wiring the
ACS-13A.
• The terminal block of this instrument is designed to be wired from the left side. The lead wire must be
inserted from the left side of the terminal, and fastened with the terminal screw.
• Tighten the terminal screw using the specified torque. If excessive force is applied to the screw whentightening, the terminal screw or case may be damaged.
• When using a terminal cover, pass terminal wires numbered 7 to 12 into the holes of the terminal cover.
• This instrument does not have a built-in power switch, circuit breaker and fuse.
It is necessary to install a power switch, circuit breaker and fuse near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)
• For a 24 V AC/DC power source, do not confuse polarity when using direct current (DC).
• Do not apply a commercial power source to the sensor which is connected to the input terminal nor
allow the power source to come into contact with the sensor.
• Use a thermocouple and compensating lead wire according to the sensor input specifications of thiscontroller.
• Use the 3-wire RTD according to the sensor input specifications of this controller.
• (+) side input terminal number of 0 to 5 V DC, 1 to 5 V DC, 0 to 10 V DC differs from that of 0 to 1 V DC.
(+) side input terminal number of 0 to 5 V DC, 1 to 5 V DC, 0 to 10 V DC: 9(+) side input terminal number of 0 to 1 V DC: 10• When using a relay contact output type, externally use a relay according to the capacity of the load toprotect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires.

3. Operation and Maintenance Precautions
Caution• It is recommended that auto-tuning (AT) be performed on the trial run.
• Do not touch live terminals. This may cause electrical shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal or cleaning.
Working on or touching the terminal with the power switched ON may result in severe injury or death
due to electrical shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)• As the display section is vulnerable, be careful not to put pressure on, scratch or strike it with a hard
object.

3.4 Mounting to and Removal from the Control Panel

CautionAs the mounting frame is made of resin, do not use excessive force while tightening
screws, or the mounting frame could be damaged.
Tighten screws with one rotation upon the screw tips touching the panel.
The torque is 0.05 to 0.06 N•m.
How to mount the ACS-13A
Mount the controller vertically to the flat, rigid panel to ensure it adheres to the Drip-proof/Dust-proof
specification (IP66).
Mountable panel thickness: 1 to 5 mm(1) Insert the controller from the front side of the panel. (Fig.3.4-1)(2) Insert the mounting frame until it comes into contact with the panel, and fasten with the screw.
Tighten screws with one rotation upon the screw tips touching the panel. (Fig.3.4-2)
The torque is approximately 0.05 to 0.06 N•m.

Gasket A

Mounting frame(Fig.3.4-1)(Fig.3.4-2)

How to remove the mounting frame and unit (Fig. 3.4-3)(1) Turn the power to the unit OFF, and disconnect all wires before removing the mounting frame.
(2) Insert a flat blade screwdriver between the mounting frame and unit 1 .
(3) Slowly push the frame upward using the screwdriver 2 , while pushing the unit toward the panel(4) Repeat Step (2) and slowly push the frame downward using the screwdriver for the other side.
The frame can be removed little by little by repeating these steps.

6. Setup
Setup (setting the Input type, Alarm type, Control action, etc.) should be done before using this controller,
according to the user’s conditions.
Factory default:
Input: K, -200 to 1370 , Alarm 1: No alarm action, Reverse (Heating) action
If the user’s specification is the same as the factory default value of the instrument, or if user’s instrument
has already been installed in a system, it is not necessary to set up the controller. Proceed to Section“7. Settings”.
6.1 Turn the Power Supply to the ACS-13A ON.
After the power is turned on, the PV Display indicates the input type, and the SV Display indicates the
input range high limit value (thermocouple, RTD inputs) or scaling high limit value (DC voltage, current
inputs) for approximately 3 seconds. (Table 6.1-1)
During this time, all outputs and the indicators are in OFF status.
Control will then start, indicating the PV (process variable) on the PV Display and SV (desired value) on the
SV Display.
While the Control output OFF function is working, the PV Display indicates.
(Indication depends on the selection in [Output status when input errors occur]).

Sensor correction
0.0• Sets the correction value for the sensor.
This corrects the input value from the sensor. When a sensor cannot be set at the exact
location where control is desired, the sensor-measured temperature may deviate from thetemperature in the controlled location. When using plural controllers, sometimes themeasured temperatures (PV) do not concur due to differences in sensor accuracy ordispersion of load capacities. In such a case, the control can be set at the desired
temperature by adjusting the input value of sensors. However, it is effective within the input
rated range regardless of the sensor correction value.

9. Auto-reset
Auto-reset is performed to correct the offset at the point at which PV indication is stabilized within the
proportional band during the PD control. Since the corrected value is internally memorized, it is notnecessary to perform the auto-reset again as long as the process is the same. However, when OUT1
proportional band (P) is set to 0 or 0.0, the corrected value is cleared.
Auto-reset is performed.

10. AT (Auto-tuning)

In order to set each value of P, I, D and ARW automatically, the AT process should be made to fluctuate
to obtain an optimal value. One of 3 types of fluctuation below is automatically selected.
For DC voltage, current inputs, the AT process will fluctuate around the SV for conditions of [1], [2] and [3] below.

Notice• Perform the AT during the trial run.
• During the AT, none of the setting items can be set.
• If power failure occurs during the AT, the AT stops.
• Sometimes the AT process will not fluctuate if AT is performed at or near room temperature.
Therefore, AT might not finish normally.
[1] If there is a large difference between the SV and PV as the temperature is rising
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20 lower than the SV.

Problem
The indication of PV Display
is irregular or unstable.

[] is indicated on the
PV Display.

Possible Cause and Solution• Check whether sensor input or temperature unit ( or ) is correct.
Select the sensor input and temperature unit ( or ) correctly.
• Sensor correcting value is unsuitable. Set it to a suitable value.
• Check whether the specification of the sensor is correct.
• AC leaks into the sensor circuit. Use an ungrounded type sensor.
• There may be equipment that interferes with or makes noise near
the controller.
Keep the instrument clear of any potentially disruptive equipment.
• Internal memory is defective.
Contact our agency or us.

Ensure that the sensor or control output terminals are mounted tothe instrument input terminals securely.
• Check whether the wiring of sensor or control output terminals is correct.
• OUT1 or OUT2 low limit value is set to 100% or higher in Setup Mode.
Set it to a suitable value.
