tion diagram [see "WT34-Bxxx, WT34-Vxxx", page 27
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
"WT34-Bxxx, WT34-Vxxx", page 27
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.

WT34-Xx4x, -Xx5x: 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
WT34-Xx1x, -Xx2x: 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 figure 3
