3. Advice on safe operation of the swing door
3.1 Behaviour of the control unit
When brought back into operation after a power failure, the control unit
carries out a test run.
X
The door opens at slow speed.
The control unit performs a system test at regular intervals:
X
This test causes an audible clicking sound.
X
When closed, the swing door presses closed several times and conducts
various tests.
X
Opening requests are not evaluated during this time.
X
During the test, if a fault occurs, e.g. someone passing through the
swing door, the swing-door drive switches into the appropriate fault
response mode. Usually, depending on its setting, it behaves like an
overhead door closer, or with spring force compensation.
The system test is repeated up the three times whenever a fault is
detected. Then an acknowledgement is required („Troubleshooting –
Acknowledgement“ on page 22).
This Inspection Book belongs to the corresponding door system and must
be available at the time of each inspection.
