Functional description
The drive is designed to work without power like a normal door closer. It can therefore be opened
easily by hand and closes with the energy stored in the spring, damped by the motor acting as a gen-
erator.
If the drive is connected to the mains, the opening and closing movements are supported by a motor.
The following functions serve exclusively for the security of the user:
Obstacle detection:
If the door hits an obstacle when opening, it stops immediately and saves the
position of the collision. During the hold-open time, the drive briefly attempts to reach the open posi-
tion. Once the hold-open time has expired, the door closes and the next time it opens, the obstacle
position is passed over in slow mode in a very restrained manner. This prevents a second hard im-
pact.
Reversing:
If the door hits an obstacle when closing, a reopening is initiated immediately.
