6 Additional functions
Alarm
Alarm output: the sensor (WT24-2Vxxx) features a pre-failure notification output
(“Alarm” in connection diagram [see „WT24-2Bxxx, WT24-2Vxxx“, page 8]), which
issues a notification if the sensor is only ready for operation to a limited extent. The LED
indicator 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).
