Alarm
Alarm output: The sensor (WTS26) features a pre-failure notification output (“Alarm”
in the connection diagram [see table 3]), 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).
