Preface
Thank you for the purchase of our Microcomputer based Temperature Indicating Controllers
GCD-200 or GCR-200.
This manual contains instructions for the mounting, functions, operations and notes when
operating the GCD-200 or GCR-200.
For model confirmation and unit specifications, please read this manual carefully before
starting operation.

To prevent accidents arising from the use of this controller, please ensure
the operator using it receives this manual.

Notes• This instrument should be used according to the specifications described in the manual.
If it is used outside the specifications, it may malfunction or cause fire.
• Be sure to follow the warnings, cautions and notices. If not, it could cause serious injury
or malfunction.
• Specifications of the GCD-200 and GCR-200 and the contents of this instruction manualare subject to change without notice.
• Care has been taken to assure that the contents of this instruction manual are correct, but if
there are any doubts, mistakes or questions, please inform our sales department.
• Any unauthorized transfer or copying of this document, in part or in whole, is prohibited.

Depending on circumstances, procedures indicated by
Caution may be linked to serious
results, so be sure to follow the directions for usage.

Warning
Procedures which may lead to dangerous conditions and cause death or serious
injury, if not carried out properly.

CautionProcedures which may lead to dangerous conditions and cause superficial to medium

SAFETY PRECAUTIONS(Be sure to read these precautions before using our products.)

1. Installation precautions
CautionThis instrument is intended to be used under the following environmental
conditions (IEC61010-1):
Overvoltage category , Pollution degree 2
Mount the controller in a place with:• A minimum of dust, and an absense of corrosive gasses• No flammable, expolsive gasses• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 )that does not change suddenly• An ambient non-condensing humidity of 35 to 85%RH• The units away from large capacity electromagnetic switches or cables• No water, oil or chemicals or where the vapors of these substances can comeinto direct contact with the unit
Note: Do not install this instrument near flammable material though the case of this
instrument is made of flame resisting resin.
Avoid setting this instrument directly on flammable material.
SAFETY PRECAUTIONS(Be sure to read these precautions before using our products.)

2. Wiring precautions
Caution• Use the solderless terminal with an insulation sleeve that fits an M3 screw
when wiring the GCD-200 or GCR-200,.
• 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 fastenedwith the terminal screw.
• Tighten the terminal screw within the specified torque.
If excessive force is applied to the screw when tightening, the screw or casemay be damaged.
3

Caution• Do not apply a commercial power source to the sensor which is connected tothe input terminal nor allow the power source to come into contact with thesensor, as the input circuit may be burnt out.
• This controller has neither a built-in power switch nor a fuse. It is necessary
to install them near the controller.
(Recommended fuse: Time-lag fuse, Rated voltage 250V, Rated current 2A)• It is recommended that the PID auto-tuning be performed on the trial run.

3. Running and maintenance precautions
Warning• Do not touch live terminals. This may cause electric shock or problems inoperation.
• Turn the power supplied to the instrunment OFF when retightening the terminaland cleaning
Working or touching the terminal with the power switched ON may result inan Electric Shock which could cause severe injury or death.
• Wipe the instrument using a soft dry cloth.
(If the paint thinner is used for wiping, the instrument may be deformed or
discolored.)• The display parts are more easily damaged. Do not strike them with hard objects
or press hard on them.

Corrects the input value from the sensor. When a sensor cannot
be set at a location where control is desired, the sensor measuring
temperature may deviate from the temperature in the controlled
location. When controlling with multiple controllers, the accuracyof sensors has influence on the control. Therefore, sometimes themeasuring temperature (input value) does not concur with thesame setting value. In such a case, the control can be set withdesired temperature by shifting the input value of sensors.

CONTROL ACTIONSGCD, GCR

6. Control actions
6.1 Explanations of PID(1) Proportional band (P)Proportional action is the action which the control output varies in proportion
to the deviation between the setting value and the processing temperature.
If the proportional band is narrowed, even if the output changes by a slightvariation of the processing temperature, better control results can be obtained
as the offset decreases.
However, if when the proportional band is narrowed too much, even slight
disturbances may cause variation in the processing temperature, and control
action changes to ON/OFF action and the so called hunting phenomenon occurs.
Therefore, when the processing temperature comes to the balanced position
near the setting value and a constant temperature is maintained, the mostsuitable value is selected by gradually narrowing the proportional band
while observing the control results.
(2) Integral time (I)Integral action is used to eliminate offset. When the integral time is shortened,
the returning speed to the setting point is accelerated. However, the cycleof oscillation is also accelerated and the control becomes unstable.
(3) Derivative time (D)Derivative action is used to restore the change in the processing temperatureaccording to the rate of change. It reduces the amplitude of overshoot andundershoot width.
If the derivative time is shortened, restoring value becomes small, and if thederivative time is adjusted to be longer, a phenomenon of excessive returning
may occur and the control system may be oscillated.

forcibly makes the controlled object’s temperature fluctuate.

OTHER FUNCTIONSGCD, GCR

6.3 Auto-reset (offset correction)
Auto-reset is performed to correct the offset at the point at which PV indicationis stabilized within the proportional band during the PD action.
Since the corrected value is internally memorized, it is not necessary to performthe auto-reset again as long as the process is the same. However,when the proportional band is set to 0, the corrected value is cleared.

When the thermocouple or RTD is burnt out or when the input value rises tothe [Rated scale maximum value +1 ( ) (or 99.9+0.1 )] or greater, the control
output is turned OFF (main output low limit value for DC current output type)].

The CPU is monitored by a watchdog timer, and when any abnormal status isfound on the CPU, the controller is switched to warm-up status.
(3) Automatic cold junction temperature compensation (Thermocouple input type)This detects the temperature at the connecting terminal between thethermocouple and the instrument, and always maintains it at the same status
at which the reference junction is located at 0 [32 ].

Notices• Use a thermocouple and compensating lead wire according to the sensor input
specifications of this controller.
• Use a 3-wire RTD according to the sensor input specifications of thiscontroller.
• This controller has neither built-in power switch nor fuse. Therefore it isnecessary to install them in the circuit near the external controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V, rated current 2A)• For the power source, 24V of AC or DC is available.
However, when using 24V DC of power source, do not confuse the polarity.
• For the relay contact output type, externally use an auxiliary electromagnetic
switch according to the capacity of the load to protect the built-in relay contact.
• When wiring, keep the input wire (Thermocouple, RTD, etc.) away from ACsource and the load wire to avoid external interference.
• Use a thick wire (1.25 to 2.0mm ) for the earth ground.

11. Troubleshooting
If any malfunctions occur, refer to the following items after checking thepower and the wiring.

Warning
Turn the power supply to the instrument off before wiring or checking.
Working or touching the terminal with the power switched on may
result in an Electric Shock which could cause severe injury or death.
