Emergency manual operation
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!
Switch off voltage.
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.
Take a safe stand.
For drive units with brake, the emergency manual operation must be carried out
against the closed brake.
Caution - Risk of injury due to unexpected movement!
The emergency manual operation has an integrated overload protection. The
overload protection causes a disconnection of the force transmission in the case of
unbalanced doors. In this case, the chain slips.
Take a safe stand.
Check the counter-balancing of the door in case of a triggering overload
protection.
Caution – Damage to components!
Do not move the door beyond the final limit positions.
