6 Additional functions
Alarm
Alarm output: The sensor (WEO26 P, WEO26 I) features a pre-failure notification output
(“Alarm” in connection diagram [
see table 6 ]), 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 or reflector is contaminated, sensor is out of alignment. In the
good state: LOW (0), if excessively contaminated HIGH (1).
Health
Health output: The sensor (WEO26 P, WEO26 I) features a pre-failure notification output
(“Health” in connection diagram [
see table 6 ]), which issues a notification if the sensor
is only ready for operation to a limited extent or the cable has been interrupted. Possi‐
ble causes: Sensor or reflector is contaminated, sensor is out of alignment, cable is
damaged. In the good state: HIGH (1), if excessively contaminated or in the event of
cable interruption LOW (0). The yellow LED indicator flashes in this case.
