Emergency manual operation (emergency hand crank)
The emergency manual operation is designed for opening or closing the door without power
supply. Its activation interrupts the control voltage. Electrical operation is no longer possible.
Warning – Injuries due to incorrect operation or falling objects!
Switch off voltage.
Adopt a secure position.
For drive units with brake, the emergency manual operation must be carried out
against the closed brake.
Warning - Danger of the door dropping!
If you need to apply more than the permissible force of 390N (according to DIN EN
12604/DIN EN 12453) to move the door by emergency manual operation, this
indicates a stalling on the drive unit or door. Releasing the stalling may cause the
door to drop.
Adopt a secure position
For drive units with brake, the emergency manual operation must be carried out
against the closed brake.
Caution – Damage to components!
Do not move the door beyond the final limit positions.
