5 Electrical installation
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Plug connection: note pin assignment: when the lid is open, the male connector
can be swiveled horizontally and vertically.
– Terminal connection: Note the permissible cable diameter of 5 to 10mm. When
the lid is open, the M16 connector can be swiveled horizontally and vertically.
Unscrew the M16 connector and remove sealing plug. Lead voltage-free supply
cable through and connect sensor in accordance with table 2 and table 5.
Retighten M16 connector with seal so that the IP enclosure rating of the device is
ensured.
Figure 2: Opening the sensor Figure 3: Electrical connection
Only apply voltage/switch on the power supply once all electrical connections have
been established.

AC/DC devices:

6 Additional functions
Alarm
Alarm output: the sensor (WE24-2Vxxx) features a pre-failure notification output
(“Alarm” in connection diagram [see „WS/WE24-2Bxxx, WS/WE24-2Vxxx“, page 9]),
which issues a notification if the sensor is only ready for operation to a limited extent.
Possible causes: sensor is contaminated, sensor is out of alignment. PNP: alarm →
M signal reserve >50% LOW, NPN: alarm → L+ signal reserve >50% HIGH. The LED
indicator flashes in this case.

Test input
Test input: the WS24-2B/-V sensors feature a test input (“TI” or “Test” on the con‐
nection diagram [see „WS/WE24-2Bxxx, WS/WE24-2Vxxx“, page 9 and see table 8]),
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 [see „WS/WE24-2Bxxx, WS/WE24-2Vxxx“, page 9 and
see 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.

7 Commissioning
1Alignment
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 figure 4]. You
must ensure that the optical openings (front screen) of the sensors are completely clear.
Figure 4: Alignment

2Sensing range
Observe application conditions: adjust the distance between the sensor and the reflector
according to the corresponding diagram [see figure 5] (x = sensing range, y = operating
reserve).
If several through-beam photoelectric sensors which are installed next to one another are
to be used, we recommend swapping the sender/receiver arrangement at every second
through-beam photoelectric sensor and ensuring that there is sufficient distance between
the through-beam photoelectric sensors. By doing this, mutual interference can be pre‐
vented [see figure 1].

3Sensitivity setting
Sensor with potentiometer: open the sensor cover and protective hood, make sure that no
dirt has gotten into the sensor.
The sensitivity is adjusted with the potentiometer (type: without stop). Clockwise rotation:
operating reserve increased; counterclockwise rotation: operating reserve reduced. We
recommend setting the potentiometer to “Maximum”.
The sensor is adjusted and ready for operation.
4Time function setting
WSE24-2xx4x: t0= no time delay, t1 = time delay, t2 = time delay; for -2R: 0 = relay
deactivated, 1 = relay active. Time delay selector switch can be set on the device according

8 Devices with special features
WSE24-2xx4x: with static front-screen heating for use in environments with gradual
temperature changes within the +5°C ... +15°C range.
WS/WE24-2V530S01: M12 male connector, 5-pin, glass front screen, dynamic power
heating on the rear side of the glass, current consumption: sender 150mA, receiver
140mA. The dynamic power heating is automatically switched on and off depending on
the ambient temperature (23-26°C). For the use of quick temperature changes in the
range of <0°C…+10°C
9 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
10 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.
11 Maintenance
This SICK sensor is maintenance-free.
We do, however, recommend that the following activities are undertaken regularly:
•Clean the optical interfaces using a plastic cleaner, do not use acetone or methy‐
lated spirits.
•Check the fittings and plug connectors
No modifications may be made to devices.
