Functional description

The C 127 X SU is designed so that it functions like a normal door closer when currentless. 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:
Obstacle 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.

Low energy drive

In the parameterisation of the Low Energy door type „Low Energy" the C 127 acts as an automatic
low energy operator. The opening and closing speeds are limited and the operator is more sensitive
in case of a collision. The closing action takes place using spring force and reduced kinetic energy.
In the currentless state, the door can be opened manually and closes automatically with the energy
stored in the spring.
CAUTION
Verletzungsgefahr durch Anstoßen am Türflügel
The low-energy drive is classified as non-hazardous. Nevertheless, collisions with certain groups of
people can cause risk of injury.
a) Clarify whether the residual risk for elderly and frail persons or persons with physical limitations
is low.
b) Observe the opening or closing speed of the door.
c) Do not rush between a closing door leaves.
