Functional description
The C 127 SU is designed so that it functions like a normal door closer when de-energised. It can
therefore be easily opened by hand and is closed by the energy stored in the spring, damped by the
motor which acts as a generator.
If the drive is connected to the mains, the opening and closing movements are motor-supported.
The following functions are solely intended for the safety of the user:
Obstruction detection:
If the door hits an obstruction while opening, it stops immediately and records the position of the colli-
sion. The drive attempts to briefly reach the open position during the hold-open time. Once the hold-
open time elapses, the door closes and, during the next opening, the obstruction position is passed
over very carefully in slow mode. This prevents a second hard impact.
Reversing:
If the door hits an obstruction while closing, re-opening is immediately initiated.
