SICK G6 Inox, Operating Instructions Manual

Page: 10 / 99

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”.
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 5: 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
receiver / Clean the optical
surfaces / Readjust the sensi‐
tivity (potentiometer) / If the
potentiometer is set to the
max. sensitivity: Reduce the
distance between the sender
and the receiver/ Check sens‐
ing range and adjust if neces‐
sary,
see table 4 .
Yellow LED lights up, no object
in the path of the beam The beam of light of a photo‐
electric through-beam sensor
hits the receiver of another
(neighboring) photoelectric
through-beam sensor Swap the sender and receiver
arrangement at every sec‐
ond through-beam photoelec‐
tric sensor and ensure that
there is sufficient distance
between the through-beam
photoelectric sensors,
see
figure 3 .
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:
