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
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.
The Troubleshooting table indicates measures to be taken if the sensor stops working.

TROUBLESHOOTING
Measures
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Ensure there is a stable power
supply without interruptions
If the power supply is OK,
replace the sensor
