1. Installation precautions
Warning
Turn the power supplied 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.

Caution
Mount the console unit 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 )• An ambient non-condensing humidity of 85%RH or less
• 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.
Tighten the terminal screw with the specified torque.
If excessive force is applied to the screw when tightening, the screw or case may be damaged.
Note
Do not install this instrument near the flammable material though the case of this instrument
is made of flame resisting resin.
Avoid setting this instrument directly on the flammable material.

2. Wiring precautions
Warning
Turn the power supplied to the instrunment 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.
The instrument must be grounded before the power supply to the instrument is turned on.

Caution• Do not put wire chips into the instrument, because they could cause fire, malfunction
or trouble.
• For the COT-200 ground terminal, use a wire whose thickness is 2mm2 or greater
However, avoid grounding in conjunction with the power line.
• Use the solderless terminal with an insulation sleeve that fits M3 screw when wiring COT-200.
• Tighten the terminal screw with the specified torque.
If excessive force is applied to the screw when tightening, the screw or case may bedamaged.
• It is advised to provide the protective device against such environmental conditions as may
cause damage to the device or contribute to the deterioration of its parts.

3. Running and maintenance precautions
Warning• Do not touch live terminals. This may cause electric shock or problems in operation.
• Turn the power supplied to the instrunment OFF when retightening the terminal and cleaning• Working or touching the terminal with the power switched ON may result in an Electric
Shock which could cause severe injury or death.

COT-200

6. Setup
After the power is supplied to this instrument, set it up as follows.
* The data transfer rate of this instrument is fixed to 19,200bps.
Set the data transfer rate of CPT-20A to 19,200bps.
6.1 Number of connected units setting
Set the number of connected CCT-235 units.
Unless the number of connected units is set, only 1 unit is monitored even if the plural units of theCCT-235 are connected.
• How to set the number of units:
In the PV/SV display mode, press the,,
key for 3 seconds or greater.
“” is indicated on the PV display and “current setting value” is indicated on the SV/MV diplay
and switches to the number of units setting mode.
At this time set the number of the CCT-235s by pressing theorkey.
The number indicated on the SV/MV display shows the number of CCT-235s connected.
Press thekey after the setting is complete.
The display returns to the PV/SV display mode.
6.2 Reading all setting values:
When the power is supplied to the COT-200 and the C series at the same time, the COT-200
automatically reads the setting data of the C series and it makes the setting data as the same
one of the C series.

CautionIf the power supply to the COT-200 is turned off and on again while the power supply to the
C series is turned on, the COT-200 cannot read the setting data of the C series automatically.
In this case, read all the setting data of the C series from the COT-200 manually.

• How to read all the setting values:
Keep pressing the,,,andkeys for 3 seconds or greater in PV/SV display mode.
” and then reverts to the PV/SV display mode again.

COT-200

7.2 Operation• After the power supply, the model name“(COT)”is indicated on the PV display for
approximately 4 seconds.
During this time, all LED indicators, as well as SV /MV and CH display are in their OFF status.
After that, the PV on the PV display, the main setting value on the SV /MV display and the channel
number being monitored on the CH display are indicated respectively, and the monitoring starts.

CautionIn the case of DC voltage and DC current input, scale change must be carried out.
When transmitting the value which is set at the COT-200 to the CCT-235, the COT-200 transmits thevalue converting it into the rated value of the CCT-235. The COT-200 converts the read value from theCCT-235 into the scaling setting range of the COT-200 and indicates it.
When setting the undividable value in connection with the scaling span of the COT-200 and the rated
value of the CCT-235, it is probable that the read value from the CCT-235 will not correspond to theset value during the process above.
(The read value will be rounded down to the nearest whole number.)
The formula for scale change when tranmitting from the COT-200 to the CCT-235 is as follows:(SV-STLL)x(CS-CZ)
Xs=(STLH-STLL)
The formula for showing the read value from the CCT-235 is as follows.

In the case of DC voltage and DC current scaling range is –1999 to 9999.
Setting range = (1999+9999) x 0.1
Therefore the setting range will be 1199.
• Sensor correction function
When a sensor cannot be set at a location where control is desired, the sensor
measuring temperature may deviate from the temperature in the controller location.
When controlling with plural controllers, the accuracy of sensors or different load
capacities affects the control.
Therefore the measuring temperature (input value) sometimes does not accord withthe same setting value.
In such a case, the control can be set with the desired value by shifting the input valueof the sensors.
