*Caution: Check position of the operating valve!
The control attempts to close the flap 3 x in the interval and perhaps eliminate the blocking object in the process.
If the object can be removed by the flap movement during these cycles, the system is ready to be used again.
If this does not work, the system switches to fault. Acknowledgement of the signal is possible.It is also possible
to remove the object by flushing the line. This can be checked by pressing the test key again. In the event of a
negative result, the fault message will appear again; the object must be eliminated as described under remedial
measure.
