Guaranteed threshold for monitored voltage OK: > 18 V, guaranteed threshold for monitored voltage faulty: < 14 V.
Terminal block wiring
The following diagram illustrates the wiring of the terminal.
NOTE: A 2 A quick blow fuse, wired to the sensor power supply IS is needed against short-circuits concerning the Cs.
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.
