3.4 Mounting and Removal

CautionAs the case is made of resin, do not use excessive force while screwing in the mounting bracket,
or the case could be damaged. The torque should be 0.12 N•m.
How to mount the unit
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 8 mm(1) Insert the controller from the front side of the control panel.
(2) Attach the mounting brackets by the holes at the top and bottom of the case, and secure thecontroller in place with the screws.

(Fig.3.4-1)
How to remove the unit
(1) Turn the power to the unit OFF, and disconnect all wires before removing the mounting brackets.
(2) Remove the mounting brackets by loosening the screws.
(3) Remove the unit from the front side of the control panel.
54. Wiring
Warning
Turn the power supply to the instrument OFF before wiring or checking.
Working on or touching the terminal with the power switched ON may result in severe
injury or death due to electric shock.

Caution• The terminal block of the WCS-13A is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened by the terminal
screw.
• Use a thermocouple and compensating lead wire that correspond to the sensor input specification of this controller.
• Use the 3-wire RTD which corresponds to the input specification of this controller.
• This controller does not have a built-in power switch, circuit breaker or fuse. Therefore, it isnecessary to install them externally, 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).
• When using a relay contact output type, externally use a relay according to the capacity of theload to protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires.
• Do not apply a commercial power source to the sensor connected to the input terminal nor allow
the power source to come into contact with the sensor.

CH1 timer starts if CH1 input exceeds CH1 timer start temperature. After CH1 timer set time has
passed, the control (CH1 output low limit value for the current output) and alarm action will stop.
However, for the Direct control action, CH1 timer starts if CH1 input drops below the CH1 timer starttemperature.
CH1 PV/SV display indicates CH1 PV. CH2 PV/SV display flashes CH1 timer remaining time.
To start control again after CH1 timer time is up, turn the power ON, or press the Reset Key.
If CH1 timer time is set to 0 (zero), the timer does not work.
If CH1 timer set value is changed while CH1 timer is working, the setting will be effective for the next use.
If CH1 timer time has passed during AT, the AT will be forcibly stopped, and each parameter returns to
the value before AT operation.
CH2 control output will be turned OFF (0 mA DC or CH2 output low limit value for the current output).
Delay Timer Function
When Delay timer function 1 is selected:
ON delay timer starts when DI input is ON (Closed), and timer remaining time will be indicated on
the CH2 PV/SV display.
Timer output turns ON after the time set in [ON Delay Timer] elapses.
After that, if DI input is turned OFF (Open), OFF delay timer starts, and timer remaining time will be
indicated on the CH2 PV/SV display.
Timer output turns OFF after the time set in [OFF Delay Timer] elapses.
When Delay timer function 2 is selected:
Control and alarm action start/stop are interlocked with the timer output.
If Delay timer is restarted, alarm action returns to its initial status (for the alarm with standby, it
returns to standby status).

Sensor Correction Function
This corrects the input value from the sensor. When a sensor cannot be set at the exact location
where control is desired, temperatures measured by the sensor may deviate from the temperature in
the controlled location.
When controlling with plural controllers, sometimes the measured temperatures do not concur due todifferences in sensor accuracy or dispersion of load capacities. In this case, the control can be set atthe desired temperature by adjusting the input value of the sensors.
However, it is effective within the input rated range regardless of the sensor correction value.

11. AT/Auto-Reset of This Controller
11.1 AT (Auto-tuning)
In order to set each value of P, I, D and ARW automatically, the auto-tuning process should be madeto fluctuate to obtain an optimal value. One of 3 types of fluctuation below is automatically selected.
For voltage and current inputs, the AT process will fluctuate around the SV for conditions of (A), (B) and (C).
Sometimes the auto-tuning process will not fluctuate if auto-tuning is performed at or near room
temperature. Therefore auto-tuning might not finish normally.
(A) If there is a large difference between the SV and PV (process variable) as the temperatureis rising
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20
lower than the SV.

11.2 Auto-Reset (Offset Correction)
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 action.
Since the corrected value is internally memorized, it is not necessary to perform the auto-reset again
as long as the process is the same.
However, when the proportional band (P) is set to 0 or 0.0, the corrected value is cleared.

To start control again after CH1 timer time is up, turn the power ON, or press the Reset Key.
If CH1 timer time is set to 0 (zero), the timer does not work.
If CH1 timer set value is changed while CH1 timer is working, the setting will become valid for the next
operation.
If CH1 timer set time has passed during AT, the AT will be forcibly stopped, and each parameter returns
to the value before AT operation.

The indication of PV/SV display
is abnormal or unstable.

The PV does not change.
The PV/SV display is indicating[].

• Check whether the input signal source for voltage (0 to 5 V DC,
0 to 10 V DC) and current (0 to 20 mA DC) is disconnected.
How to check whether the input signal wire is disconnected[Voltage (0 to 5 V DC, 0 to 10 V DC)]If the input to the input terminal of this controller is 1 V DC, and if
a value (converted value from Scaling high, low limit setting)corresponding to 1 V DC is indicated, the controller is likely to be
operating normally, however, the signal wire may be disconnected.
[Current (0 to 20 mA DC)]If the input to the input terminal of this controller is 4 mA DC, and if
a value (converted value from Scaling high, low limit setting)corresponding to 4 mA DC is indicated, the controller is likely to be
operating normally, however, the signal wire may be disconnected.
• Check whether the input lead wire terminals for voltage (0 to 5 V DC,
0 to 10 V DC) or current (0 to 20 mA DC) are securely mounted tothe instrument input terminals.
• Check whether sensor input or temperature unit ( or ) is correct.
Select the sensor input and temperature unit ( or ) properly.
• 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 equipment that interferes with or makes noise away from thecontroller.
• SV may be selected in [CH indication].
Select PV other than the SV.
• Internal memory is defective.

13.3 Control
ProblemTemperature does not rise.

The control output remains in an
ON status.
The control output remains in an
OFF status.
CH1 timer does not work.

Delay timer does not work.

Possible Cause and Solution• Sensor is out of order.
Replace the sensor.
• Check whether the Sensor or control output terminals are securely
mounted to the instrument input terminals.
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 iscorrect.
• Output low limit value is set to 100 % or higher in the CH1, CH2function groups.
Set it to a suitable value.
• Output high limit value is set to 0 % or less in the CH1, CH2function groups.
Set it to a suitable value.
• CH1 timer time may be set to 0 (zero) seconds.
Set it to a suitable value.
• CH1 timer start temperature should be set suitably.
Timer starts when CH1 input exceeds CH1 timer start temperature.
For the Direct control action, timer starts when CH1 input drops
below CH1 timer start temperature.
Set it to a suitable value.
• Delay action time unit, ON delay timer or OFF delay timer
should be set suitably.
Set them to suitable values.
