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 sensors WTL16, WTS16 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.
If an object is detected, activate the test input (see the connection diagram
The send LED is shut down or no object being detected is simulated. Refer to
to check the function. If the switching output fails to behave in accordance with the
graphic, check the application conditions.
