Alarm: Operation with borderline light reception
Alarm output: The sensor (WSE4F) features a pre-failure notification output ("Alarm"
in the connection diagram), which issues a notification if the sensor is only ready for
operation to a limited extent. The LED flashes in this case. Possible causes: Sensor
is contaminated, sensor is out of alignment. In the good state: LOW (0), if excessively
contaminated HIGH (1).
Health
Health output: The sensor (WSE4F) features a pre-failure notification output ("Health"
in the connection diagram), which issues a notification if the sensor is only ready for
operation to a limited extent or the cable has been interrupted. Possible causes: Sensor
