4 System Functions
It is the responsibility of the system operator to ensure that
the automatic sliding door can be freely used at all times and
particularly that access to the sliding door is not blocked.
4.1 Automatic Door Operation with Sensors
When operating automatically (AUTOMATIC operating mode) the door is automatically opened from
both sides by sensors when a person approaches.
A key switch
u
or card reader
u
normally allows access from outside when the door is in operating
mode EXIT or OFF. The door unlocks, opens and closes again as soon as no further sensors are ac-
tivated after a hold-open time which is set separately. The sensors for the door opening and the main-
tained opening of the door are arranged and adjusted in such a way that the door opens promptly and
remains open as long as a person is within the operating range of the door leaves. The door can close
nevertheless but only after an attendance time of approx. > 1 minute.
The reduced closing speed which is set by the installer and is adjusted in line with the door weight,
combined with a force of < 150 N prevents the impact of the moving leaves on a person from being too
severe. The obstruction is also detected by the control system and the door automatically reverses.
4.2 Traffic Control
Movement through the door can be allowed in only one direction if desired (operating mode EXIT) or
completely blocked (operating mode OFF). In order to protect against environmental influences (wind/
cold/heat) the door can be operated in operating mode AUTOMATIC 2 with a restricted opening width
which is not less than the required escape route width.
4.3 Automatic System Monitoring
The control system monitors the safety sensors by a cycle of active tests. The control system also
conducts continuous internal system tests. If a safety-related component should fail, the system auto-
matically switches into a safe condition. At the same time the fault number is displayed on the user
interface. You can find further information on this subject in chapter 5 “Procedure in the Event of Faults”.
4.4 Electro-mechanical Lock
u
The system can be locked in the closed position by means of an electro-mechanical lock
u
or held in
the closed position by a holding magnet
u
when in operating mode OFF and, if required, in other op-
erating modes (e.g. EXIT). The locking process is monitored. Thus any fault of the locking operation
can be immediately displayed on the user interface. See chapter 5 “Procedure in the Event of Faults”
for details. In the event of a power failure the locks can also be directly activated by the optional
manual facility.
4.5 Operation in the Event of a Power Failure
Depending on the equipment installed, the following functions are possible:
– Immediate emergency opening or closing by a mechanical energy store
u
or emergency closing.
– Immediate unlocking (only if programmed by the installer).
– Continued operation of the system by means of a battery unit
u
for a specific time with the doors
opening before the battery switches off. The door remains locked in operating mode OFF.
– Unlocking and opening of the door from outside by means of a key switch and the battery unit
