Test input: The WSE9(M4)-3 sensor features a test input ("TI" or "Test" on the connecti‐
on diagram [B]), which can be used to 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.
WSE9M4-3P3410S02: High-power IR, increased operating reserve, sensing range max.
13 m, light spot size 140 mm (1 m distance), response time < 1 ms, switching frequen‐
cy 500 Hz
