7 Additional functions
Alarm
Alarm output: the sensor (WE34-Vxxx) features a pre-failure notification output (“Alarm”
in connection diagram [
see "WS/WE34-Bxxx, WS/WE34-Vxxx", page 7 ]), which issues a
notification if the sensor is only ready for operation to a limited extent. Possible causes:
sensor is contaminated, sensor is out of alignment. PNP: Alarm
→ M signal reserve
> 50% LOW, NPN: Alarm → L+ signal reserve > 50% HIGH. The LED indicator flashes in
this case.
