How to release your shutter in the event of a power failure

LIRITIS electric operated rolling shutters that are equipped with a main motor can be also manually operated through the motors’ metal lanyard, if need arises. The metal lanyard is fitted either to the inner side of the opening within a plastic cone or to the exterior of the opening in a metal box with a key (blidoor). Manual operation through the plastic cone can be achieved after we undo the cone, so that the lanyard starts being pulled, the motor brake releases, and the shutter starts operating manually. Manual operation through blidoor can be achieved after we place the key in the blidoor. We open blidoors’ door and we immobilise it by pulling the clutch on the top of the door. We operate the shutter manually. After use, it is recommended that we checked the proper operation of the motors’ release lock. Special attention should be paid during the lock release, since the shutter can move abruptly upwards or downwards depending on the state of the springs.

 

In the event of a power failure or an implication with the motor

  • We undo (in the case of an internal lock release) or pull (in the case of an external lock release) slowly and attentively the manual operation.
  • Attention!! It is possible that the shutter might roll abruptly either upwards or downwards depending on the state of the springs.
  • Will lift or pull down the shutter slowly and cautiously by setting our hands on the desirable point.
  • Attention!! The shutter needs to be lifted up to the point that it can be easily reached.
  • We fix (in the case of an internal lock release) or push (in the case of an external lock release) the manual operation so as to activate the motor.
  • We check if the motor activation is successful. We need to make sure that the shutter is secured in our attempts to shake or mobilise it.

 

When the power returns or the motor implication resolves

  • We check if the lock release is in the motor activation position. If it isn’t, we fix (in the case of an internal lock release) or push (in the case of an external lock release) the manual operation so as to activate the motor.
    • Note: The shutter does not necessarily need to be in the same position, as when we released it.
  • We check if the motor activation is successful. We need to make sure that the shutter is secured in our attempts to shake or mobilise it.
  • We operate the shutter by pressing the button or using the remote control.
