Test input
Test input: The sensors WLA26 feature a test input ("TI" or "Test" on the connection
diagram [see 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
to check the function. If the switching output 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 [see
optical openings of the sensor and reflector are completely clear.
