System description

The revolving door has a full automatic, microprocessor controlled drive system, which can be used in
several operating modes.
The revolving door has a counter clockwise rotation unit, with fixed side glass panels on each outer
side and radial protective sliding wing extensions. These serve as pinch protectors and absorb the ro-
tating mass by sliding back and simultaneously stopping the rotational movement when touched.
The rotary unit is in the middle and is equipped with an integrated double wing automatic sliding door,
two pivot wings, which can be opened manually (optional) or with fixed glazing.
The rotary unit is powered by two synchronized DC motors. The drive is activated by radar motion de-
tectors. If the motion detectors are no longer activated, the rotation unit will slow down then stop in
the start position.
Safety sensors prevent hazardous movement and slow down and/or stop the rotation unit in time.
An integrated error-analyzer detects malfunctions. The error code will appear on the control unit
(BDE-D) display, a separate one for revolving doors (BDE-D-KTA) and sliding doors (BDE-D-STA).
This control unit can be used to select the various operating modes and also to program the basic
door parameters.
