7.5 Wiring for Digital Input Terminals:
Generally, shielded cable is recommended and wiring distance should be as short as possible.
When the analogue reference signal is used, it is necessary to take measures to prevent
power supply interference (noise).
Digital input terminals are only connected for NPN mode (source) or for PNP mode (sink).
Select NPN or PNP mode by sliding the switch J7 to “NPN” or “PNP”.
Wiring for control terminals as follows:
7.5.1 Wiring for positive source electrode (NPN mode).
7.5.2 Wiring for active source electrode
If digital input control terminals are connected by sink electrode, slide the toggle switch to the
end of “PNP”. Wiring for control terminals as follows:
