The switch is factory-set to 0.
Note If the Unit number is set to an existing Unit number, an alarm occurs and the
C200H does not operate.
Turn the C200H power off before setting the Unit number. If the setting is
changed with the power on, the new setting is not valid until the power is turned
off and back on again.

The switch is factory-set to OFF.
Input Approximation Set each loop to either straight line (no approximation) or square root approxi-
mation.
Loop 2 Set to “enabled” to use input loop 2, or to “disabled” to use only input loop 1. It is
not possible to use only input loop 2.
Note Always set this switch to the ON (disabled) position when input loop 2 is not
used. A sensor error occurs if this switch is set to the OFF (enabled) position
when no temperature sensor is connected to loop 2.
SP Write Mode This setting selects the SP storage memory. Set it to ON or use RAM Write com-
mands if the writing is to be frequently changed.
Display Units Selects whether setting and SVs displayed on the Data Setting Console are in
Celsius or Fahrenheit.
Control Action Reverse:
The output is increased when the measured temperature is below the SP (i.e., a
negative temperature difference).
Normal:
The output is increased when the measured temperature is above the SP (i.e., a
positive temperature difference).
Control Method Selects the method of control.

Input Wiring Precautions
1, 2, 3...

1. The PID Control Unit will not operate correctly if the SW202 setting does not
match the type of inputs that are connected. In addition, each loop can be
connected to either voltage inputs or current inputs, but not to both. For example, if Loop 1 is set for voltage input, then current input will not work.
2. If no input lead is connected to Loop 2, turn SW203-4 on the rear of the Unit
ON to disable Loop 2. A sensor error occurs if this switch is set to the OFF
(enabled) position when no sensor is connected to Loop 2.
3. Be sure to wire the polarity correctly for each input.
4. Wire I/O leads in separate ducts from power leads to prevent noise problems.
5. A voltage of 24 VDC is used for the voltage output, current output and Data
Setting Console power supply.
6. The terminal block is removable. Make sure that it is attached correctly after
the input wiring connections are completed.
