Ventilation/alarm/relief/reversing stroke

Ventilation stroke
The value range for ventilation stroke and alarm stroke parameters can be set using the service terminal ST220.
The alarm stroke cannot be smaller than the ventilation stroke. The software restricts the max. ventilation stroke
to the alarm stroke set.
Relief stroke
The relief stroke defines the extent to which the load on the drive is relieved after the closing position has been
reached.
Reversing stroke
The reversing stroke defines the extent to which the drive is reversed if the window is obstructed before the
open or closing position is reached.

Ventilation braking/ventilation acceleration

Ventilation braking
à The "ventilation braking", "open brakes" parameters describes the brake ramp during opening and reversing.
à The "ventilation braking", "close brakes" parameters describes the brake ramp during closing and reversing.
Ventilation acceleration
à The "ventilation expedite", "open exp" parameters describes the expediting ramp during opening and rever-
sing.
à The "ventilation expedite", "close exp" parameters describes the expediting ramp during closing and rever-
sing.
Possible damage to the window!
High expediting values lead to high start-up current.
Only change the settings following consultation with GEZE.

Alarm acceleration/alarm braking

These parameters cannot be set and are only displayed.

Closing position force

This parameter describes the closing force during finding of the closing position.
The teaching run always occurs at max. force. The force to reach the overload cut-off remains unaffected by this.
The closing force influences the airtightness and life span of the windows and fitting parts.
The setting may only be made by specialist authorised personnel.
