Explanation
Hinge side
The side of the door where the hinges from which the door leaf is suspended are locat-
ed. Usually that side of the door located in the opening direction.
Opposite hinge side
The side of the door facing the hinge side. Usually that side of the door located in the
direction of closing movement.
Active leaf
The active leaf of a double-leaf door. When someone passes through the door, the
active leaf must open as the first door leaf and close as the last door leaf.
Passive leaf
The secondary leaf of a double-leaf door. When the door is used, the passive leaf may
not open until the active leaf has left the closing position and must close again as the
first door leaf.
Activation device inside (KI)
Push button, switch or movement detector for activating the door drive.
The activation device is located within the room enclosed by the door.
Activation function in the AUTOMATIC and EXIT ONLY modes of operation.
The activation device does not have any function in the NIGHT/OFF mode of operation.
Activation device outside (KA) Push button, switch or movement detector for activating the door drive.
The activation device is located outside the room enclosed by the door.
Activation function in the AUTOMATIC mode of operation. The activation device does
not have any function in the EXIT ONLY and NIGHT/OFF modes of operation.
Activation device
authorised (KB)
Access control function (for example key switch or card reader) used by authorised
persons to activate the door drive.
The activation function is active in the AUTOMATIC, EXIT ONLY and NIGHT/OFF modes
of operation.
Activation device with current
impulse function
Push button for opening and closing the door. Activation function only in the AUTO-
MATIC and EXIT ONLY modes of operation. The door is opened automatically when the
button is first pressed and closed again automatically when the button is pressed the
second time. The function can be activated during commissioning by setting parame-
ters using the display programme switch, ST 220 or GEZEconnects. If the activation de-
vice is connected to the passive leaf control system by means of the “current impulse”
function, both door leaves open when activated, even when the passive leaf control
system is deactivated.
Push&Go
When the door is pressed manually out of the closing position with an activated
Push & Go function in the AUTOMATIC operating mode, the door opens automatically
as soon as a specific adjustable opening angle is exceeded.
Opening safety sensor (SIO)
Presence detector (e.g. active infrared light switch) for protecting the swinging range
of the door in the opening direction. As a rule the sensor is located on the hinge side of
the door on the door leaf.
Closing safety sensor (SIS)
Presence detector (for example active infrared light switch) for protecting the swinging
range of the door in the closing direction. As a rule the sensor is located on the oppo-
site hinge side of the door leaf.
Emergency stop
Self-locking switch with which immediate stopping of the door drive can be triggered
in case of danger. The door drive remains in its current position until the user releases
the emergency stop switch again, thus terminating the emergency stop situation.
Low-energy function
The GEZE Powerturn can be used as a low-energy drive.
In low-energy function the force needed for opening and closing the door is reduced
to 67 N and the opening and closing time is reduced. This lowers the danger of a per-
son bumping into the moving leaf.
If people who are particularly vulnerable pass through the door, special measures must
be taken to eliminate the contact hazard (e.g. use of open/ closing safety sensor).
