Technical Information: Photoelectric sensors, SICK Smart Sensors /
This SICK sensor is maintenance-free.
We do, however, recommend that the following activities are undertaken regularly:
Clean the optical interfaces and housing
Check the fittings and plug connectors
Cleaning
NOTICE
Equipment damage due to improper cleaning.
Improper cleaning may result in equipment damage.
Only use recommended cleaning agents and tools.
Never use sharp objects for cleaning.
Clean the optical surfaces at regular intervals and, in the event of contamination,
with a lint-free lens cloth (part number 4003353). The cleaning interval essentially
depends on the ambient conditions.
Cause
Voltage interruptions
Sensor is faulty
Test input (Test) is not con‐
nected properly
IO-Link communication
IO-Link communication
Parameter settings made
manually, which deviate from
the standard
The sensor is not ready for
operation. The sensor will be
in the warming-up phase at
low ambient temperatures.
The sensor will have shut
down at excessively high
ambient temperatures.
Distance between the sensor
and the background is too
short
Distance between the sensor
and the object is too long or
sensing range is set too short
Measures
Ensure there is a stable power
supply without interruptions
If the power supply is OK,
replace the sensor
See the note on connecting
the TI
-
-
Initiate a factory reset. The
digital outputs are reset to
factory settings.
At low ambient temperatures,
wait until the sensor has
warmed up. Ensure the sensor
cools down at excessively high
ambient temperatures.
Check the teach-in mode
Reduce the sensing range,
