Test input: The WS/WE14-2 sensor features a test input ("TI" or "Test" on the connec‐
tion diagram [B]), 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 the TI is assigned accordingly.
There must be no object between the sender and receiver; activate the test input (see
the connection diagram [B], TI at 0 V). The send LED is shut down or the detection of an
object is simulated. Refer to Graphics C and G to check the function. If the switching
output fails to behave in accordance with Graphic C, check application conditions. See
section Fault diagnosis.
