Alarm output: The sensor (WLG4S-3) features a pre-failure notification output ("Alarm"
in connection diagram [B]), which issues a notification if the sensor is only ready for
operation to a limited extent. Possible causes: Sensor or reflector is contaminated, sen‐
sor is out of alignment. In the good state: LOW (U
HIGH (>+U - V). The LED indicator flashes in this case.
