1. Installation Precautions
Caution
This 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 not
change 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 with the unit
• If the WCL-13A is installed within a control panel, the ambient temperature of the unit - not the
ambient temperature of the control panel - must be kept to under 50 . Otherwise the life of
electronic parts (especially electrolytic capacitors) of the unit will be shortened.
Note • Do not install this instrument on or near flammable material even though the case 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 the
WCL-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 or fuse.
It is necessary to install them 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 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 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 electric 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 electric 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, do not strike or scratch it with a hard object or put
pressure on it.

(1)Pass the heater wire into the hole of CT, and solder the wires of the wire harness provided.
There is no polarity.
(2) CH1: Insert the wire harness into the CH1 CT input connector.
CH2: Insert the wire harness into the CH2 CT input connector.

5.9 Wiring Example of Serial Communication (C5 option)
When the Serial Communication (C5 option) is added, a modular jack is equipped at the bottom of the
controller.
Wiring example using the IF-400 communication converter
•D-sub 9-pin Connector
(Fig. 5.9-1)
•D-sub 25-pin Connector
(Fig. 5.9-2)
Shielded Wire
Connect only one end of the shielded wire so that current cannot flow to the shielded wire. If both ends
of the shielded wire are connected, the circuit will be closed between the shielded wire and the ground.
As a result, current will run through the shielded wire and 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 a personal computer with multiple
peripheral devices. The terminator prevents signal reflection and disturbance.
Do not connect the terminator with the communication line because the WCL-13A has built-in pull-up
and pull-down resistors instead of a terminator.

6. Outline of Key Operation and Setting Groups
6.1 Outline of Key Operation
Setting items are divided into groups, and group selection has to be made with keypads.
Press the key in the PV/SV display mode. The unit enters the Group selection mode.
Select a group with the , and press the . The unit enters each setting item.
To set each setting item, use the or key, and register the value with the key.
6.2 Setting Groups
The following shows the setting group configuration.

• , : This means that if the or key is pressed, the unit proceeds to the next setting item.
• : This means “Press the key until the desired setting mode appears”.
(*1) In the PV/SV display mode, indicates a setting item selected in the Display selection.
(*2) Indications differ depending on the selection in the CH1, CH2 parameter group.
(*3) In the PV/SV display mode, the PV/SV indications will switch.
PV(SV) does not switch if a CH1, CH2 difference or addition inclusive item is selected during
Display selection in the Special function group.
(*4) Not available for Potentiometer input spec.
(*5) Not available for Timer spec, Potentiometer input spec or if Heating/Cooling control or External
setting input is selected from the Block function (Console software).
(*6) Not available for Timer spec, Potentiometer input spec or if Heating/Cooling control is selected from
the Block function (Console software).
(*7) If Cascade control spec is selected from the Block function (Console software), CH1 SV will
become theAT point of the slave side.
(*8) Not available for Timer spec or if Heating/Cooling control or External setting input is selected from
the Block function (Console software).
