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 directcontact with the unit
• If the WCL-13A is installed within a control panel, the ambient temperature of the unit – not theambient temperature of the control panel – must be kept to under 50 . Otherwise the life ofelectronic parts (especially electrolytic capacitors) of the unit will be shortened.
Note: Do not install this instrument directly on or near flammable material even though thecase of this instrument is made of flame-resistant resin.

2. Wiring Precautions
Caution• Do not leave wire remnants in the instrument, because they could cause a fire or a malfunction.
• Use a solderless terminal with an insulation sleeve in which the M3 screw fits when wiring theWCL-13A.
• Tighten the terminal screw using the specified torque. If excessive force is applied to the screw
when tightening, the terminal screw may be damaged.
• 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 specificationsof this controller.
• Use the 3-wire RTD according to the sensor input specifications of this controller.
• When using a relay contact output type, externally use a relay according to the load capacity
to protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC power sources or load
wires.

3. Operation and Maintenance Precautions
Caution• It is recommended that auto-tuning be performed during the trial run.
• Do not touch live terminals. This may cause an 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 witha hard object.

Shield Wire
Connect only one end of the shield wire so that current cannot flow to the shield wire. If both ends of theshield wire are connected, the circuit will be closed, resulting in a ground loop. This may cause noise.
Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use a twisted
pair cable.)
Terminator (Terminal Resistor)
The terminator is mounted at the end of the wire when connecting multiple peripheral devices to apersonal computer. The terminator prevents signal reflection and disturbance.
Do not connect a terminator to the communication line because the WCL-13A has built-in pull-up andpull-down resistors.

• Setting range: -100.0 to 100.0 ( ) DC voltage, current inputs: -1000 to 1000 (Theplacement of the decimal point follows the selection.)[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, the sensor-measured temperature may deviate from thetemperature in the controlled location. When using multiple controllers, sometimes themeasured temperatures do not concur due to differences in sensor accuracy or dispersion ofload 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 rating range regardlessof the sensor correction value.
PV after sensor correction= Current PV+ (Sensor correction value)(e.g.) When PV is 198 :If sensor correction value is set to 2.0 , PV will be 198 + (2.0) = 200.0 .
If sensor correction value is set to -2.0 , PV will be 198 + (-2.0) = 196.0 .

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 multiple controllers, sometimes themeasured temperatures do not concur due to differences in sensor accuracy or dispersionof load capacities. In such a case, the control can be set at the desired temperature byadjusting the input value of sensors. However, it is effective within the input rating range
regardless of the sensor correction value.
PV after sensor correction= Current PV+ (Sensor correction value)(e.g.) When PV is 198 :If sensor correction value is set to 2.0 , the PV will be 198 + (2.0) = 200.0 .
If sensor correction value is set to -2.0 , the PV will be 198 + (-2.0) = 196.0 .

10.5 Performing Cascade Control
Cascade control of the WCL-13A
To control one process, 2 inputs [CH2 as a master (1st-order controller), and CH1 as a slave (2ndorder controller)] are used for more advanced control.
MV is calculated from PV and SV of the master (CH2), and is used as SV of the slave (CH1), withwhich CH1 control calculation is carried out, then outputs from CH1 control output.
[CH2 control output will be turned OFF (0 mA for direct current output) or will become OUT2 for
Heating/Cooling control. See the “CH2 output” in (Fig. 10.5-1).]
MV (0 to 100%) of the master (CH2) corresponds to the SV (External setting scaling low limit toExternal setting scaling high limit) of the slave (CH1).

12. AT/Auto-Reset of This Controller

12.1 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 DC voltage, current input, the AT process will fluctuate around the SV for conditions of (A), (B), (C) below.
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 as the temperature is rising
When AT bias is set to 20 , the AT process will fluctuate at the temperatures 20 lower than the SV.

12.2 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.
Since the corrected value is internally memorized, it is not necessary to perform auto-reset again aslong as the process is the same.
However, when the proportional band (P) is set to 0 or 0.0, the corrected value is cleared.

When the power is turned on, the control starts from the PV, andapproaches the SV by the rate-of-change.
Automatic or Manual control can be switched by keypad operation.
If control action is switched from automatic to manual and vice versa, thebalanceless-bumpless function works to prevent a sudden change inmanipulated variable.
When automatic control is switched to manual control, manual MV is
indicated on the display. (The switched CH1 or CH2 display flashes.)
When power is turned on, control action starts from its previous controller
status (last shutdown).
Control timer or Delay timer is selectable via keypad.
• Control timer
Control timer starts if CH1 input exceeds Control timer start temperature,
and after Control timer time has elapsed, control (Output low limit value
for direct current output) and Alarm action will stop.
• Delay timer
Delay timer starts when DI input is ON (Closed). Timer output turns on
after ON delay timer time has passed.
Timer output turns off after OFF delay timer time has passed.
To control one process, 2 inputs [CH2 as a master(1st-order controller), andCH1 as a slave (2nd-order controller)] are used for more advanced control.
MV is calculated from PV and SV of the master (CH2), and is used as SVof the slave (CH1), with which CH1 control calculation is carried out, thenoutputs from CH1 control output.
[CH2 control output will be turned OFF (0 mA for direct current output) or
will become OUT2 for Heating/Cooling control.]CH2 will be a master (1st-order controller), CH1 will be a slave (2nd-ordercontroller).

[] is indicated on
the PV/SV Display.
14.2 Key Operation
Problem• Settings (SV, P, I, D,
proportional cycle,
alarm value, etc.) are
impossible.
• The values do notchange by theorkey.
The setting indication
does not change within
the rated input range
even if theor
key is pressed, and newvalues are unable to be
set.

Possible Cause
Check whether the input signal wire
for DC voltage (0 to 5 V DC, 0 to 10
V DC) or direct current (0 to 20 mADC) is disconnected.

Check whether the input signal wire
for DC voltage (0 to 5 V DC, 0 to10 VDC) or direct current (0 to 20 mA DC)
is securely connected to thecontroller input terminals.
Check whether the sensor input or
temperature unit ( , ) is correct.
Sensor correction value is notsuitable.
Check whether the sensor
specification is correct.
AC leaks into the sensor circuit.
There may be equipment thatinterferes with or makes noise near
the instrument.
SV may be selected in [Display
selection] in the Basic function group.
The internal memory is defective.

Solution
How to check whether the input
signal wire is disconnected[DC voltage(0 to 5 V DC, 0 to 10 V DC)]If the input to the input terminal ofthis controller is 1 V DC, and if avalue (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 bedisconnected.
[Direct current (0 to 20 mA DC)]If the input to the input terminal ofthis controller is 4 mA DC, and if avalue (converted value from Scaling
high, low limit setting) corresponding
to 4 mA DC is indicated, thecontroller is likely to be operating
normally, however, the signal wire
may be disconnected.
Connect the signal wire to thecontroller input terminals securely.

Set the sensor input and thetemperature unit ( , ) correctly.
Set it to a suitable value.
Set the sensor specification properly.
Use an ungrounded type sensor.
Keep the instrument clear of any
potentially disruptive equipment.
Select any indications other than SV.
Please contact our main office ordealers.

Possible Cause“Lock” is selected in [Set value lock]in the Basic function group.
During AT or auto-reset.

Solution
Release the “Lock” selection.

Scaling high or low limit value in theCH1, CH2 function group may be set
at the point where the value does notchange.

Set it to a suitable value.

65

In the case of AT, cancel AT.
It takes approximately 4 minutes until
auto-reset is finished.

Problem
CH2 SV cannot be set.

Possible Cause
Timer spec is selected, or Heating/Cooling control output or Externalsetting input is selected from theBlock function (Console software).

CH2 parameter groupis not indicated.

Timer spec or Potentiometer input
spec is selected, or Heating/Cooling control output or Externalsetting input is selected from theBlock function (Console software).

CH2 function group is
not indicated.

Timer spec or Potentiometer input
spec is selected, or Heating/Cooling
control output is selected from theBlock function (Console software).

14.3 Control
Problem
The PV (temperature)
does not rise.

The control output
remains in an ON
status.
The control output
remains in an OFF
status.

Control timer does not
work.

Delay timer does notwork.

Solution
If Timer spec is selected, or if Heating/Cooling control output or Externalsetting input is selected from theBlock function (Console software),[CH2 SV] setting item will not be
indicated.
If Timer spec or Potentiometer input
spec is selected, or if Heating/Cooling
control output or External setting input
is selected from the Block function(Console software), CH2 parametergroup will not be indicated.
If Timer spec or Potentiometer input
spec is selected, or if Heating/Cooling
control output is selected from theBlock function (Console software),
CH2 function group will not be
indicated.

Possible Cause
The sensor is out of order.
Check whether the sensor is securely
mounted to the instrument input
terminals, or control output terminals
are securely mounted to the actuator
input terminals.
Ensure that wiring of sensor
terminals or control output terminals
is correct.
OUT low limit value is set to 100%or higher in CH1, CH2 function group.

Solution
Replace the sensor.
Mount the sensor or control output
terminals securely.

“Control Prohibited” has been
selected in [Control Allowed/
Prohibited] in CH1, CH2 parametergroup.
OUT high limit value is set to 0% orless in the CH1, CH2 function group.
Control timer time is set to 0 (zero)seconds in the Basic function group.
Control timer start temperature in the
Basic function group is not set to asuitable value.

Select “Control Allowed”.

Timer action time unit, ON delay
timer or OFF delay timer in the Basic
function group is not set to a suitablevalue.

66

Wire them correctly.
Set it to a suitable value.

Set it to a suitable value.
Set it to a suitable value.
Timer starts when CH1 input exceeds
Control timer start temperature.
(In the case of Direct control action,
timer starts when CH1 input drops
below Control timer start temperature.)
Set it to a suitable value.
Set it to a suitable value.
