Additional functions
Alarm
Alarm output: the sensor (WT34-Vxxx) features a pre-failure notification output (“Alarm”
in connection diagram [
see "WT34-Bxxx, WT34-Vxxx", page 7
]), which issues a notifica‐
tion 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 align‐
ment. In the good state: LOW (0), if excessively contaminated HIGH (1).
