Input Wiring Precautions
1, 2, 3...
1. Set the type of temperature sensor to thermocouple or platinum resistance
thermometer with SW202 on the rear of the Unit.
The Unit will not operate correctly if the switch setting does not match the
type of temperature sensor connected.
Do not connect different types of temperature sensors to Loop 1 and Loop 2.
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 temperature sensor is connected to Loop 2.
3. Be sure to connect (+) and (–), and (A) and (B) correctly.
4. Wire I/O leads in separate ducts from power leads to prevent noise prob-
lems.
5. A voltage of 24 VDC is used for the voltage output, current output and Data
Setting Console power supply. (The power for the transistor output is sup-
plied from the output connector.)
6. The terminal block is removable. Make sure that it is attached correctly after
the input wiring connections are completed.
Tighten the terminal block screws to a torque of 0.8 N
