The following illustration shows the circuit diagram for a wiring check input.
1
Guaranteed threshold for monitored voltage OK: > 18 V, guaranteed threshold for monitored voltage faulty: < 14 V.
2
Resistance R for a dry contact or a 3-wire proximity sensor enables the input wiring check to be used.
The following illustration shows the circuit diagram for a 24 V -2 A transistor output.
1
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: you must wire an external 1 A quick blow fuse on the sensor power supply and 20 A on the preactuator power supply.
The
four terminals +OS
x,y must be wired together via an external shunt, reference
TBX RV 015. The -SV, -IS and -OS terminals must also be wired together.
