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 ex-
ample, 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 prob-
lems.
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.
