Fault description and troubleshooting
!"# $%
Error in the internal SPI data transmission or error in the internal motor control sequence.
Solution:
Disconnect the power supply to the control unit for approximately 10 seconds. If the problem persists replace the con-
trol unit.
& '
Fault has occurred in the sensor test sequence.
Solution:
Disconnect the power supply to the control unit for approximately 10 seconds. If the problem persists replace the con-
trol unit.

Solution:
Check the data that you have entered using the Service Port software, e.g. a passive IR sensor cannot be combined
with a radar sensor.
* + 9%
The WPS2 detected a fault while checking the actual output voltage against the desired output voltage. If this is the
case, the motor output will be switched off.
Solution:
Before commissioning can be carried out again, the WPS2 system must be disconnected from the power supply for 10
seconds. This fault will also arise if the WPS2 system is operated with external line monitoring with diodes connected
and without a load via a drive.

control unit.
