Alarm output: the sensor (WE24-2Vxxx) features a pre-failure notification output

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
