NoticeAs the case is made of resin, do not use excessive force while screwing in the mounting bracket.
The torque is approximately 0.12N•m.
When the one-touch type mounting brackets
are used:
Mountable panel thickness is 1 to 3mm.
Set the mounting bracket 1 to the top
and bottom of the instrument first.
Then, insert the GCS-300 2 from thefront of the mounting panel.
When the Soft-type Front-cover is used,mountable panel thickness is 1 to 2.5mm.

When the screw type mounting brackets(BL option) are used:
Mountable panel thickness is 1 to 15mm.
Insert the GCS-300 from the front of the panel.
Attach the mounting bracket by the holes at the
top and bottom of the case, and secure the unit
in place with the screws.
When the Soft-type Front-cover (FS-48-S) isused, mountable panel thickness is 1 to 14.5mm.

Notice• The terminal block of the GCS-300 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.
• Use a thermocouple and compensating lead wire in accordance with the input specifications of this controller.
• Use a 3-wire RTD according to the input specifications of this controller.
• This controller does not have a built-in power switch or fuse. Therefore, it is necessary to install themin the circuit near the external controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V, rated current 2A)• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).
• With the relay contact output type, externally use an auxiliary electromagnetic switch in accordancewith the capacity of the load to protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources and load wires to avoid
external interference.

5. Operations

HeaterAfter the power is turned on, the PV display indicates the sensor characters and temperature unit, andthe SV display indicates the input range high limit value for approx. 2 seconds. See (Table 5-1).
(When any other value has been set during the SV high limit setting, the SV display indicates the value.)
During this time, all outputs and LED 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.
(When the control output OFF function is working,is indicated on the PV display.
To release the control output OFF function, press the
key for approx. 1 second.)(Table 5-1)

After the unit is mounted to the control panel and wiring is completed, operate the unit following theprocedures below.
(1) Turn the power supply to the GCS-300 ON.
For approx. 2 seconds after the power on, the sensor type characters and temperature unit are
indicated on the PV display, and the input range high limit value is indicated on the SV display.
See (Table 3.1-1). (If any other value is set during the SV high limit setting, SV display indicatesthe value.)
During this time, all outputs and LED indicators are in OFF status.
After that, the PV display indicates the current temperature, and the SV display indicates the
SV (desired value).
While the Control output OFF function is working, [] is indicated on the PV display.
(2) Input each set value.
Input each set value referring to Chapter “5 Operations”.
(3) Turn the load circuit power ON.
Control action starts so as to maintain the control target at the SV.

].

When the thermocouple input value falls below -50 (-100 ), the control output is turned
OFF (for DC current output type, OUT low limit value), and the PV display flashes [].
For the RTD input, when Input range low limit value is -19.9, if the input value falls below-50 (-100 ), the control output is turned OFF (for the current output type, OUT low limit value),and the PV display flashes [].
For the RTD input, when Input range low limit value is -199, if the input value falls below[-199 – 1% of the input span], the control output is turned OFF (for DC current output type,
OUT low limit value), and the PV display flashes [].
(2) Sensor burnout (Burnout)
When the thermocouple or RTD is burnt out, the control output is turned OFF (for DC current
output type, OUT low limit value), and the PV display flashes [].
(3) Self-diagnosis
The CPU is monitored by a watchdog timer, and when an abnormal status is found on the CPU,the controller is switched to warm-up status.
(4) Automatic cold junction temperature compensation (thermocouple input type)This detects the temperature at the connection terminal between thermocouple and the instrument,
and always keeps it at the same status as when the reference junction is located at 0 (32 ).

9. PID 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.
Note: Sometimes the auto-tuning process will not fluctuate if auto-tuning is performed at or nearroom temperature. Therefore auto-tuning might not finish normally.
• In the case of a large difference between the SV and processing temperature as thetemperature is rising
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20 lower than the SV.
