Closing sequence control
Electrical closing sequence control
In normal operation of double-leaf door drives, the closing sequence of the door leaves
is controlled by the control units of the door drives, with the passive leaf being closed
first. The active leaf remains in the open position until the passive leaf has reached the
closed position, then the active leaf begins to close.
Integrated closing sequence control (-IS)
The closing sequence is controlled mechanically in the case of a power failure at dou-
ble-leaf door systems with Powerturn F-IS and Powerturn F-IS/TS. The door leaves are
closed by means of the power storage device of the drives, with the active leaf being
kept open by the integrated mechanical closing sequence control. When the passive
leaf has reached the closed position, it releases the active leaf by means of the mechan-
ical elements of the closing sequence control so that it can also close completely.
Electric strike
Electric strike fail safe
Available as AC or DC electric strike version. When the door drive is activated, the
electric strike is switched on by the control unit of the door drive provided the door is
in the closed position. The electric strike remains activated until the door has left the
closed position.
Electric strike fail secure
DC electric strike version. The electric strike is switched off when the door drive is acti-
vated provided the door is in the closed position. The electric strike remains switched
off until the door has left the closed position.
Bar message feedback
The bar message feedback function is a contact integrated in the door catch that is
activated when the door is locked mechanically by the tie bolt of the door lock. It sig-
nals to the control unit that the door is locked mechanically and can therefore not be
opened by the door drive. In this case the control unit ignores the control commands
of all the activation devices.
Reset
Button for restarting the drive after the operating voltage has been switched on or
after a fire alarm has been terminated. When the button is pressed, the self-retention
integrated in the drive is activated, causing the drive to be activated.
Latching function
When the door is closed in a de-energised state, the door leaf is impeded by the lock
latch of the electric strike. To make sure the door can pass the lock latch safely during
closing, an integrated limit switch is actuated in the drive once a specific opening an-
gle has been reached, reducing the braking strength. The door accelerates and closes
into the lock at increased speed. In an energised state, this function is regulated by the
drive control unit.
Door closer mode
In automatic mode (normal mode) the automatic swing door automatic drive can
behave like a door closer. This means that closing is torque-controlled. This closing
torque can be adjusted and adapted to the respective passage situation.
Servo operation
If servo operation is used, the swing door drive supports manual passage through
moment of force (Siehe Review-Datei von November). The support moment of force
and the support period can be set for this support.
