Alarm
Alarm output: The sensor (WTS26) features a pre-failure notification output ("Alarm" in
connection diagram [see table
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).
Health output: The sensor (WTS26) features a pre-failure notification output ("Health"
in connection diagram [see table
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 interrup‐
tion LOW (0). The LED indicator flashes in this case.
Test input
Test input: The WTS26 sensors feature a test input ("TI" or "Test" on the connection
diagram [see table 2, table 3
and, therefore, check that the sensor is functioning correctly: If female cable connec‐
tors with LED indicators are used, you have to ensure that the TI is assigned accord‐
ingly.
If an object is detected, activate the test input (see the connection
table 3 and table 5]). The send LED is shut down or no object being detected is simu‐
lated. Refer to table 5 to check the function. If the switching output fails to behave in
accordance with table 5, check the application conditions. See section Fault diagnosis.
