Function during a power failure
CAUTION
Danger of people being trapped inside the turnstile.
a) Bruises and contusions through from the turnstile wing.
ð
Visual inspection, check whether people are trapped inside.
In the event of a power failure, the rotation is stopped immediately and the turnstile is then freely ro-
tatable.
The key emergency operation button or start button are without function.
NOTICE
An emergency operation is only possible for a certain bridge period with an external (on-site)
or integrated UPS (Uninterruptible Power Supply).
If the system is equipped with a bistable electric turnstile lock, the turnstile remains locked in the basic
position in the operating mode LOCKED.
If a monostable closed lock is installed, the system is locked from any operating mode.

Conduct during power failure
7.4.1
Revolving door conduct during power failure
In the operating modes "Automatic", "Continuous" and "One Way" the rotation unit rotates to the cross
position with help from the integrated emergency power supply and then shut down.
The message "Power failure" is displayed on the BDE-D control unit.
Depending on the configuration, the sliding doors will remain operational during power failure or they
will open and stay open.
In the revolving door operating modes "Locked", "Manual" or "Cross position" the rotation unit remains
in its current position.
7.4.2
Revolving door conduct when power is restored
NOTICE
After power is restored, the message "Power failure" will disappear off the control unit. De-
pending on the duration of the power failure, either the previous operating mode will resume
or for safety reasons, the restart lock will be activated and the revolving door will remain at a
standstill. This will be displayed on the BDE-D control unit.
The restart lock must be cancelled manually on the BDE-D first before the revolving
door can operate again.
