System error 3 (braking circuit)
The braking circuit is a safety element in the closer
mode and will be tested every 24 hours. During
the test, the motor is shut down during the closing
movement and the door closes a set angle in the
emergency mode. The test can be noticed as a
short jerk on the door panel and is no reason for a
complaint.
The door closes in the deenergized state too fast
(in under 3 seconds).
Check and reduce, if necessary, the closing speed (see
page 24, point 5.13).
If the test is always negative despite the correctly set
closing speed, the control unit must be replaced.

Energy management
The motor is too hot (e.g. due to an excessive
ambient temperature).
The system responds automatically.
The movement dynamics in the CLOSED direction will
be reduced.
- 2 The movement dynamics in the OPEN and CLOSED
direction will be reduced.
- 3 The system shuts down for 3 minutes
(door closer mode).
- 4 The hold-open time will be extended.
