Test input
Test input: The WLA16 sensors feature a test input ("TI" or "Test" on the connection
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.
It is important that there is no object between the sensor and reflector; activate the
test input (see the connection diagram). The send LED is shut down or the detection
of an object is simulated. Refer to
fails to behave in accordance with the graphic, check the application conditions.

Table 6: Test
Align the sensor with a suitable reflector. Select the position so that the red emitted
light beam hits the center of the reflector. The sensor must have a clear view of the
reflector, with no object in the path of the beam
optical openings of the sensor and reflector are completely clear.
