5 Electrical installation
The sensors must be connected in a voltage-free state (UV = 0V). The following informa‐
tion must be observed depending on the connection type:
– Plug connection: pin assignment
– Cable: wire color
Only apply voltage/switch on the voltage supply (UV >0V) once all electrical connec‐
tions have been established.

5.1 Notes on UL approval
The device shall be supplied from an isolating transformer having a secondary overcur‐
rent protective device that complies with UL 248 to be installed in the field rated either:
a) max 5 amps for voltages 0 ~ 20 V (0 ~ 28.3 V peak), or
b) 100 / Vp for voltages of 20 ~ 30 V (28.3 ~ 42.4 V peak).
Alternatively, they can be supplied from a Class 2 power supply.
UL Environmental Rating: Enclosure type 1
6 Commissioning
6.1 Alignment
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 figure 4].
Figure 4: Alignment
6.2 Sensing range
Adjust the mounting position to ensure the sensing range and the background are
within the specifications. See see figure 5, page 11.
NOTE
Observe the minimum distance of 5mm.

Check the function as described in see table 2, page 9. If the switching output fails to
behave as described in see table 2, page 9, check the application conditions.

6.3 Settings
Sensing range setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
The sensing range is adjusted with the potentiometer (type: 5-turn). Clockwise rotation:
sensing range increased; counterclockwise rotation: sensing range reduced. We recom‐
mend placing the object within the sensing range, e.g. see figure 5. Once the sensing
range has been adjusted, the object is removed from the path of the beam, which
causes the background to be suppressed and the switching output to change [see
table 2].
Table 3: Adjustment sensing range
The sensor is adjusted and ready for operation.
7 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 4: Troubleshooting
LED/fault pattern Cause Measures
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
No voltage or voltage below
the limit values
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Voltage interruptions Ensure there is a stable power
supply without interruptions
Sensor is faulty If the power supply is OK,
replace the sensor
Yellow LED flashes Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
object / Clean the optical sur‐
faces / Check sensing range
and adjust if necessary

8 Disassembly and disposal
The sensor must be disposed of in line with applicable country-specific regulations.
When disposing of them, you should try to recycle them (especially the precious met‐
als).
NOTE
Disposal of batteries, electric and electronic devices
•According to international directives, batteries, accumulators and electrical or
electronic devices must not be disposed of in general waste.
•The owner is obliged by law to return this devices at the end of their life to the
respective public collection points.
•
WEEE: This symbol on the product, its package or in this document,
indicates that a product is subject to these regulations.
9 Maintenance
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.
bClean the optical surfaces at regular intervals and, in the event of contamina‐
tion, with a lint-free lens cloth (part number 4003353) and plastic cleaner (part
number 5600006). The cleaning interval essentially depends on the ambient
conditions.
No modifications may be made to devices.
