Closing sequence control
Electrical closing sequence control
In normal operation of double leaf drive units, the closing sequence of the door leaves
is controlled by the control units of the drive units, 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)
In the event of a power failure, the closing sequence is controlled mechanically on double
leaf door systems with Slimdrive EMD-F-IS. The door leaves are closed by means of the
power storage device of the drives, with the active leaf being kept open by the integrat-
ed mechanical closing sequence control. When the passive leaf has reached the closing
position, it releases the active leaf by means of the mechanical elements of the integrated
closing sequence control so that it can also close completely.
Electric strike
Fail-secure electric strike
Available as AC or DC electric strike version. When the drive unit is activated, the elec-
tric strike is switched on by the control unit of the drive unit provided the door
is in the closing position. The electric strike remains activated until the door has left
the closing position.
Fail-safe electric strike
DC electric strike version. The electric strike is switched off when the drive unit is acti-
vated provided the door is in the closing position. The electric strike remains switched
off until the door has left the closing position.
Bolt feedback
The bolt feedback function is a contact integrated in the lock latch that is activated
when the door is locked mechanically by the tie bolt of the door lock. It signals to the
control unit that the door is locked mechanically and can therefore not be opened
by the drive unit. In this case the control unit ignores the control commands of all the
activation devices.
Reset
Push button for restarting the drive after the operating voltage has been switched
on or after a fire alarm has been terminated. When the push button is pressed, the
latching integrated in the drive is activated, causing the drive to be switched on.
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 activated 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 operation) the automatic swing door 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 opening through
moment of force. The support torque and the support period can be set for this support.
