Example:
Leaf weight: 90 kg, leaf width 1000 mm
The opening and closing time must be set to 5 s.
If the drive does not fulfil these requirements, it is in low-energy mode. The leaf movement must then be safe-
guarded using protective devices.
26 Servo mode
The GEZE Powerturn drive can be operated as a servo drive. It provides torque-controlled support to users dur-
ing manual passing.
The servo drive is operated and set within the automatic operating mode.
The power support is divided into 2 functional areas:
à
Servo support without fire alarm with additional torque
à
Servo support with fire alarm with additional torque
26.1 Servo support without fire alarm with additional torque
The drive is power-supported during manual door opening so that the door can easily be used manually even
under difficult environmental conditions, such as wind or against pressure in a stairwell. The power-assisted func-
tion is adjustable.
The door can be manually accelerated to the maximum speed of the low-energy function. Once this speed is
reached, the drive brakes the door movement.
The following parameters must be set:
à
Servo duration (
aD
): Duration of the servo support from activation
à
Additional servo torque (
a O
): power-supported torque for easy manual opening
When activated via KI, KA, PE-KI, PE-KA, PE switch function, FK1, FK2, or KI+SIS, KA+SIS or with a Push & Go angle
set, the drive opens the door with the set additional servo torque. The drive closes the door once again upon
expiration of the set servo duration (
aD
).
When activated via KB, the drive opens under speed regulation with the set values “Opening force”, “Closing
force”, “Opening time” and “Closing time”.
à
The additional servo torque (
a O
) must be set for the low energy mode.
à
The SIO and SIS sensor strips are evaluated and react as set. During the night, the drive does not reverse if
there is a blockade, but rather presses against the obstacle with the set force or torque.
