■ Input signal and measuring range
※ CAUTION
-
Measuring input wiring
- When wiring the measuring input line, disconnect the controller body and external power
supply to avoid a danger of electric shock.
- Pay attention to the polarity of the input before connecting. Wrong connection
may result in malfunction.
- Use shielded wires for input wiring. The shield must be grounded at
single-point.
- For measuring input signal, wire after leaving room between the power supply circuit
and the ground circuit, if possible.
