Test input
Test input: The sensors WTF26 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 background; 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 11: Test
WTF26P: Align sensor on background. Select the position so that the red emitted light
beam hits the objects. You must ensure that the optical opening (front screen) of the
sensor is completely clear [see
WTF26I: Align the sensor with the background. Select the position so that the infrared
light (not visible) hits the objects. The correct alignment can only be detected via the
LEDs, see figure 5 and table
of the sensor is completely clear.
