3 Sensitivity setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
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.
4 Test input
Test input: The GRSE18(S)V sensors feature a test input (“TI” or “Test” on the connection
diagram [
table 2 ]), 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 must 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 [
table 2 ], TI 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 Troubleshooting
The Troubleshooting table indicates which measures are to be taken if the sensor stops
working.

Table 7: 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
Green LED lights up, no output
signal when object is detected Test input (Test) is not con‐
nected properly See the note on connecting
the TI
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
