The input disconnection detection function can be used when the input signal
range is set for 1 to 5 V (4 to 20 mA).
Allocation for Adjustment
Mode
For adjustment mode, set the operation mode switch on the rear panel of the
Unit as shown in the following diagram. When the Unit is set for adjustment
