Test input
Test input: The WTF16 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.
If an object is detected, activate the test input (see the connection diagram). The send
LED is shut down or no object being detected is simulated. Refer to
function. If the switching output fails to behave in accordance with the graphic, check
the application conditions.
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

WTF16P: Align the sensor with the object. Select the position so that the red emitted
light beam hits the center of the object. It is important to ensure that the optical
opening (front screen) of the sensor is completely clear
WTF16I: 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 1 and table
of the sensor is completely clear.
