1 Safety notes
■Read the operating instructions before commissioning.
■
Connection, mounting, and setting may only be performed by skilled per‐
son.
■Not a safety component in accordance with the EU Machinery Directive.
■Power supply: Class 2
Enclosure type 1
■When commissioning, protect the device from moisture and contamination.
■These operating instructions contain information required during the life cycle of
the sensor.
2 Intended use
The GL6V is an opto-electronic photoelectric retro-reflective sensor (referred to as “sen‐
sor” in the following) for the optical, non-contact detection of objects, animals, and per‐
sons. A reflector is required for this product to function. If the product is used for any
other purpose or modified in any way, any warranty claim against SICK AG shall become
void.

4 Mounting
Mount the sensor and the reflector using suitable mounting brackets (see the SICK
range of accessories). Align the sensor and reflector with each other.
< 0.4 Nm
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:
– Male connector 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. The green LED indicator lights up on the sensor.

6 Commissioning
1Alignment
Align the sensor with a suitable reflector. Select the position so that the red emitted light
beam hits the center of the reflector. The sensor must have a clear view of the reflector,
with no object in the path of the beam [see figure]. You must ensure that the optical open‐
ings of the sensor and reflector are completely clear.

2Sensing range
Adjust the distance between the sensor and the reflector according to the corresponding
diagram [ see figure 3] (x = sensing range, y = operating reserve).

3Sensitivity setting
The sensitivity is adjusted with the potentiometer (type: 270°). Clockwise rotation: operat‐
ing reserve increased; counterclockwise rotation: operating reserve reduced. We recom‐
mend setting the potentiometer to “Maximum”. A lower operating reserve may be neces‐
sary for depolarizing surfaces.
The sensor is adjusted and ready for operation.
7 Troubleshooting
The Troubleshooting table indicates which measures are to be taken if the sensor stops
working.

7.1 Troubleshooting table
Table 4: Troubleshooting
LED indicator/fault pattern Cause Measures
Green LED does not light up No voltage or voltage below
the limit values
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Green LED does not light up Voltage interruptions Ensure there is a stable power
supply without interruptions
Green LED does not light up Sensor is faulty If the power supply is OK,
replace the sensor
Yellow LED flashes Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Check the operating condi‐
tions: Fully align the beam of
light (light spot) with the
reflector / Clean the optical
surfaces (sensor and reflec‐
tor) / Readjust the sensitivity
(potentiometer) / If the poten‐
tiometer is set to the max.
sensitivity: Reduce the dis‐
tance between the sensor and
the reflector, and check the
reflector type / Reflector is not
suitable for the application in
question (we recommend only
using SICK reflectors)/ Check
sensing range and adjust if
necessary, see table 3. / Dis‐
tance between the sensor and
the reflector is too long
Signal interruptions when
object is detected
Depolarizing property of the
object surface (e.g., tape),
reflection
Reduce sensitivity or change
the position of the sensor
8 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).
9 Maintenance
SICK sensors are maintenance-free.
We recommend doing the following regularly:
•Clean the external lens surfaces
•Check the screw connections and plug-in connections
No modifications may be made to devices.
