EMERGENCY MANUAL RELEASES
The manual emergency release is envisaged for opening and closing the door in case of power
failure, so it is to be used only in emergency situations.
- Avoid regular use!!
Warning! Danger of injury in the case of incorrect use!
- Deactivate the main switch before using the manual emergency release.
- The manual emergency release is to be executed only with the motor stopped.
- The manual emergency release maneuver is to be executed from a safe place.
- With a gearmotor equipped with brake (pressure), the main door must be opened and closed with
the brake open (released).
- On doors not balanced with weights, the brake is to be released only for checking purposes with the
door in the low position for safety reasons.
- An undesirable brake release must be prevented with an adequate check (measurement) on site.
The manual emergency release must not move the door beyond the final positions because in this
case the main switch would activate.
Therefore, operation of the door in electrical mode is no longer possible. Handle-operated manual
emergency release (fig. 3)
- Insert the handle exerting moderate pressure, then turn it up to when it clicks in position. In this
way the control voltage is interrupted and the door can no longer be activated electrically.
- Open and/or close the door turning the handle
- The control voltage is reset and the door can again be activated electrically by removing the handle.
Manual chain-operated emergency release (fig. 4 and 9)
- Movement to the right or left activates a microswitch that will cut out the voltage going to the
reduction unit, afterwards the main door can be opened or closed by pulling the chain.
- After releasing the chain, the voltage will be restored and the reduction unit will once again be
operational. Average duration: 200 cycles! Manual chain-operated emergency release 2 (fig. 5a-d)
- Grasp the red handle / manual control (1) and softly pull until stopping to interrupt the control
voltage, and therefore prevent activation of the door in electric mode.
- Open and/or close the door with the emergency release chain (2)
- Grasp the green handle /motor control (3) and softly pull until stopping to restore the control
voltage, and therefore once again consent operation of the door in electric mode.
Average duration: 350 cycles! Interlocking release (fig. 6)
- Pull the red cable to release the gearmotor.
- Manually move the door upwards or downwards.
- Pull the green cable to once again lock the gearmotor.
Modification of the length of the emergency release chain (fig. 7)
- The emergency release chain opens in the connection point and therefore can be extended or
shortened by adding or removing links.
- The links must be carefully bent.
- When the emergency release chain length is modified, it is necessary to pay attention
WARNING: Max. chain length: 14 meters - max. assembly height 8 m!!!
NOTE: with chains having lengths min. 15 meters it is
necessary to use the “2” chain release.
