4.C. Use of the emergency manual operator
Depending on the characteristics of the door, there are two possibilities for manual operation if necessary:

4.C.1. Crank drive

EN
Once it has been checked that the door cannot be operated, the following steps must be taken:
• Remove the crank from its holder and insert it into the designated housing, turning it as far as it will go (1).
When performing this operation, the control phase is interrupted and the electric drive of the door is also
non-operational.
• Apply the shaft brake lever to release the shaft and make the door easier to open
• Open the door manually by turning the handle (2). The shaft brake must be kept free during this manoeuvre.
ATTENTION: Reconnect the shaft brake before releasing the crank. If this is not done, the door will close abruptly.
• After finishing the manual operation, the crank is removed and returned to its original position. This also puts
the electrical system of the motor back into operation.

4.C.2. Chain drive

Once it has been checked that the door cannot be operated, the following steps must be taken:
• Pull the red handle to activate the release system.
When performing this operation the electric door drive is switched off.
• Pull the chain to open or close the door manually.
• Pull the green handle to deactivate the release system.
This causes the electrical system of the motor to start up again.
ATTENTION: Under no circumstances should the door be unlocked without
first disconnecting the power supply.
