NOTE
When mounting through beam photoelectric sensors adjacent to each other, alternate
the sender (ZSO18) and receiver (ZEO18) arrangement every other pair. Also ensure
that there is sufficient distance between pairs based on the sender (ZSO18) light spot
diameter. Refer to figure 2 and table 1.

6 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.
Explanation of connection terminology used in Tables 2-5:
BN = Brown
WH = White
BU = Blue

7 Commissioning
1Alignment
ZSE18-xxxxx2, -xxxxx8: align the sender (ZSO18) with the receiver (ZEO18). Select the posi‐
tion so that the red emitted light beam hits the receiver. Tip: Use white paper as a reflector
for the sender 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 5]. Ensure that the optical openings (front
screen) of the sensors are completely clear.
ZSE18-xxxxx1, -xxxxx3: align the sender (ZSO18) with the receiver (ZEO18). Select the posi‐
tion so that the infrared light (not visible) hits the receiver. The correct alignment can only
be detected via the LED indicators on the receiver. See figure 5 and table 2. The sender
must have a clear view of the receiver, with no object in the path of the beam. Ensure that
the optical openings (front screen) of the sensors are completely clear.

Figure 5: Alignment
2Sensing range
Observe the application conditions: Adjust the distance between the sender and the
receiver according to the corresponding diagram [see figure 6 and see figure 7, page 13]
(x = sensing range, y = operating reserve).
When mounting through beam photoelectric sensors adjacent to each other, alternate the
sender (ZSO18) and receiver (ZEO18) arrangement every other pair. Also ensure that there
is sufficient distance between pairs based on the sender (ZSO18) light spot diameter. By
doing this, mutual interference can be prevented [see figure 2].
Use table 2 to check the function. If the switching output fails to behave in accordance with
table 2, check the application conditions.

3Sensitivity setting
Sensor not possible to be set: The sensor has been adjusted by the factory to provide maxi‐
mum sensitivity and is ready for operation.
4Operation with marginal light reception
The sensor will provide a pre-failure notification by flashing the orange LED indicator when
operating with marginal light reception. This may be the result of incorrect alignment or
contaminated optical surface(s). The sensor may be equipped with a Health or Alarm out‐
put, which provide a discrete signal when the sensor is operating in the marginal condition.
Refer to table 3 for additional detail on Health/Alarm output operation.
8 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 6: Troubleshooting
LED indicator/fault pattern Cause Measures
Yellow LED does not light up
even though the sender is
aligned to the receiver and
there is no object in the path of
the beam
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
No object in beam path, no out‐
put signal
Test input (Test) is not con‐
nected properly
Check connection of the test
input. When using female
cable connectors with LED
indicators, make sure the test
input is assigned correspond‐
ingly.
Yellow LED flashes; if Alarm /
Health is present then take
note of the corresponding out‐
put signal
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Check the operating condi‐
tions: Fully align the sender
and receiver / Clean the opti‐
cal surfaces

9 Disassembly and disposal
The sensor must be disposed of according to the applicable country-specific regula‐
tions. Efforts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).
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.
•
This symbol on the product, its package or in this document, indicates
that a product is subject to these regulations.
10 Maintenance
SICK recommends the following regular maintenance:
•Clean the external optical surfaces
•Check the screw connections and plug-in connections
No modifications may be made to devices.
