Alarm
Alarm output: The sensor (WTL16, WTS16) features a pre-failure notification output
("Alarm" in connection diagram
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 output: The sensor (WTL16, WTS16) features a pre-failure notification output
("Health" in connection diagram
is only ready for operation to a limited extent or the cable has been interrupted.
Possible causes: Sensors are contaminated, sensors are 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 LED flashes in this case.
Test input
Test input: The WTL16, WTS16 sensors feature a test input ("TI" or "Test" on the con‐
nection diagram [table 2], which can be used to switch the sender off and, therefore,
check that the sensor is functioning correctly: If female cable connectors with LED
indicators are used, you have to ensure that the TI is assigned accordingly.
