Switch example
It can be operated with the key reversing switch.
Opening process:
the night shield is opened by turning the key reversing switch to the right
(see arrow direction) and holding the position. If the night shield is locked electrically, then it
will simultaneously unlock. The opening process will stop when the key reversing switch is
no longer being turned or held. The opening process will resume by turning the key to the
right again and holding the position.
Closing process:
the night shield is closed by turning the key reversing switch to the left
and holding the position. The closing process will stop when the key reversing switch is no
longer being turned or held. If the night shield is locked electrically, then it will lock automat-
ically in the locked position.
Collision detection:
if a night shield wing hits an obstacle during the opening or closing pro-
cess, the night shield will stop and remain stopped. The next opening or closing process will
start when the key reversing switch is turned and held in position again.

Night shield
NOTICE
The door is equipped with a night shield located on the exterior entrance.
If it is manually pushed out of the open position while rotating, the turnstile will immediately
stop for safety reasons.
For safety reasons, the automatic mode only functions if the night shield is completely open.
During a power failure, the status of the night shield remains LOCKED or UNLOCKED.
3.5.7
Fully automatic night shield
It is operated with a door open button, or a turn key switch, or an on-site code card reader.
CAUTION
Night shield crushing danger
a) Fingers or hands getting crushed, sheared or pulled in
ð
To avoid crushing, the operator must have a clear view of the night shield during the OPENING
and CLOSING process.
Fully automatic night shield drive with electric lock:
Place the door in the LOCKED operating mode.
The night shield is closed and electrically locked.
By pressing the door open button, or using the turn key switch or on-site code card reader, the night
shield will unlock and open up completely.
Once the night shield is completely opened, the turnstile will start, turn one complete rotation at slow
speed and come to a standstill in the home position.
Then the night shield closes again automatically and locks.
In the operating modes AUTOMATIC, CONTINUOUS and MANUAL, the night shield unlocks itself,
opens automatically and remains open. If switched to the LOCKED operating mode, the night shield
closes again automatically.
Security sensors:
if the detection area of the security sensors is entered during the closing process,
the night shield will open (reverse) immediately. If no security sensors are activated the night shield
will close and lock automatically.
Collision detection:
if the night shield wing strikes an obstacle during the closing process, the night
shield will stop and open again. The next attempt to close will start from the obstruction area at slow
speed.
The night shield will also stop, if its wing strikes and obstacle during the opening process. The next at-
tempt to open will start at slow speed.

The revolving door is off and is locked through an integrated turnstile lock and motor brake. When the
