Normal operation

7.1.1 Lock
The following describes operation on the device. The same behaviour applies for opera-
tion with a remote control and with the central control unit. but a different letter/number
is shown on the display (see previous section).
• Press the button "Lock" (F) on the door lock drive. "M" is shown on the display.
The lock bolt moves to the previously defined locking position and the symbol
"Locked" ( ) appears. Upon completion of the procedure, a long signal tone is
emitted on the door lock drive.
If the lock has been turned on the inside with the handwheel or with a key from
outside in the meantime, for safety reasons it does not move to the "Locked"
position but turns to the stop in the direction "Locked" instead.

A jammed lock (after previous manual actuation with the handwheel or with the key) is
recognized as stop "Locked" if necessary. In this case, the symbol "Locked" ( ) may be
shown and the acoustic acknowledgement signal may be emitted, although the lock is
not fully locked. If the error is only a fault that occurs during normal operation (because
of temperature influence for example), the jam can be eliminated by attempting the lock-
ing procedure again.
7.1.2 Unlock
The following describes operation on the device. The same behaviour applies for
operation with a remote control and with the central control unit but a different letter/
number is shown on the display.
• Press the button "Unlock" (D) on the door lock drive (top button). "M" is shown
on the display.
After the procedure is completed, two short signal tones are emitted on the door
lock drive.
7.1.3

Opening the door

This function is only possible if the pressure of the door seals is sufficient to
press the door open slightly, after the door lock drive has retracted the opening
latch. This function can only be used with a remote control or the central control
unit. The door behaves as if the latch was pressed.
• Press the "Open door" button on the remote control.
The LC display shows the flashing symbol "Unlock", the door lock drive retracts
the opener latch. The normal pressure of the door seal against the door opens
the door slightly.
The drive is then moved back to the neutral position and the symbol "Unlock" stops
flashing.
7.2

Emergency operation

We recommend that you use a lock cylinder with emergency and hazard
functionality (double cylinder). These locks allow locking and unlocking from the
outside or inside independent of the other.
With a standard lock cylinder, the door can no longer be unlocked from the
outside if a key is inserted inside. If a defect occurs or the batteries are too low,
the door can no longer be opened without damaging it!
Locking/unlocking the lock manually can be done in the following two ways:
