The following illustration shows the circuit diagram for a resistive input.

Guaranteed threshold for monitored voltage OK: > 18 V, guaranteed threshold for monitored voltage faulty: < 14 V.
The following diagram illustrates the wiring of the terminal.
NOTE: the Cs terminals are not protected against short-circuits, so a 2 A quick blow fuse, must be wired to the sensor power supply IS.
It is not necessary to connect the two +IS terminals together, nor the two -IS terminals. The -SV terminal and a -IS (0 V) terminal must however be connected together.
