Test input
Test input: the WS34-B / -V sensors feature a test input ("TI" or "Test" on the con‐
nection diagram [see "WS/WE34-Bxxx, WS/WE34-Vxxx", page 25
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.
There must be no object between the sender and receiver; activate the test input
(see the connection diagram
table 8], TE at 0 V). The send LED is shut down or the detection of an object 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.
Table 8: Test
1 Alignment
Align the sender with the receiver. Select the position so that the red emitted light beam
hits the receiver. Tip: Use white paper or a reflector as an alignment aid. The sender must
have a clear view of the receiver, with no object in the path of the beam [see
must ensure that the optical openings (front screen) of the sensors are completely clear.
