2. Place an object in the detection fi eld of sensor 1. Make sure that the detection
fi eld of sensor 2 remains clear.
- Green LED “Power” is lit
- Yellow LEDs “OUT 1” and “OUT 1.2” are lit
- USi-PP: Outputs 1.1 and 1.2 are closed
USi-IP/UP: analog Signal at output 1.1, output 1.2 is closed
- Yellow LEDs “OUT 2” and “OUT 2.2” are off
- Outputs 2.1 and 2.2 are open
1. Make sure that the detection fi elds from sensor 1 and sensor 2 are clear.
- Green LED “Power” is lit
- All yellow LEDs are off
- All outputs are open
Testing the Function
4. Place an object in the detection fi eld of Sensor 2. Make sure that the detection
fi eld of Sensor 1 remains clear.
- Green LED “Power” is lit
- Yellow LEDs “OSSD 1.1” and “OSSD 1.2” are off
- Outputs 1.1 and 1.2 are open
- Yellow LEDs “OSSD 2.1” and “OSSD 2.2” are lit
- Outputs 2.1 and 2.2 are closed
3. Repeat Step 1.
All tests passed? – If so, your USi is now ready for operation.
The following description applies for USi with two sensors.
For USi with only one sensor, the functional test is completed after Step 2.
TIP: Diagnosis . Lack of earthing may cause malfunctions. With the Continuous
echo diagnostics
in the parameter assignment software (optional), you can
quickly detect a lack of earthing.
