Test input
Test input: the WT24-2B / -V sensors feature a test input ("TI" or "Test" on the connec‐
tion diagram [see "WT24-2Bxxx, WT24-2Vxxx", page 7
used to switch the sender off and, therefore, check that the sensor is functioning cor‐
rectly: 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
"WT24-2Bxxx, WT24-2Vxxx", page 7
shut down or no object being detected is simulated. Use the following table to check the
function. If the switching output fails to behave in accordance with the following table,
check the application conditions. See section Fault diagnosis.

WT24-2Xx4x, -2Xx5x: align sensor on object. Select the position so that the red emitted
light beam hits the center of the object. You must ensure that the optical opening (front
screen) of the sensor is completely clear [see
WT24-2Xx1x, -2Xx2x: align sensor on object. Select the position so that the infrared light
(not visible) hits the center of the object. The correct alignment can only be detected via
the LED indicators. See
(front screen) of the sensor is completely clear.
