SICK WSE16 Series, Operating Instructions Manual

Health
Health output: The sensor (WEO16P, WEO16I) features a pre-failure notification output
(“Health” in connection diagram
table 5 , which issues a notification if the sensor is only
ready for operation to a limited extent or the cable has been interrupted. Possible
causes: Sensor or reflector is contaminated, sensor is out of alignment, cable is dam‐
aged. 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.

Test input
Test input: The sensors (WSO16P, WSO16I) feature a test input (“Test” in table 6 ),
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 must
ensure that Test is assigned accordingly.
There must be no object between the sender and receiver; activate the test input (see
the connection diagram
table 6 , Test at 0 V). The send LED is shut down or the detec‐
tion of an object is simulated. Refer to table 4 , table 6 to check the function. If the
switching output fails to behave in accordance with table 4 , check the application con‐
ditions. See section Troubleshooting.
