Figure 8: Time functions
WT34-V210S01, WT34-R210S02: preset to dark switching
WT34-B400S04: preset to light switching, light spot size approx. Ø 15 mm (1 m)
WT34-R210S06: close range blanking (no detection between 0 and 80 mm)
WT34-R220S07: black cover between sender and receiver
The Troubleshooting table indicates measures to be taken if the sensor stops working.

LED/fault pattern
Yellow LED does not light up
even though the light beam is
aligned to the object and the
object is within the set sensing
range
Object in beam path, no output
signal
Yellow LED flashes; if Alarm is
present then take note of the
corresponding output signal
0.5 ... 10 sec.
0.5 ... 10 sec.
0.5 ... 10 sec.
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Test input (Test) is not con‐
nected properly
Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
Measures
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Ensure there is a stable power
supply without interruptions
If the power supply is OK,
replace the sensor
Check connection of the test
input. When using female
cable connectors with LED
indicators, make sure the test
input is assigned correspond‐
ingly.
Check operating conditions:
align light beam (light stop)
completely on the object /
cleaning of optical surfaces /
check sensing range and
adjust if necessary.
