Description of the roller door safety devices
To monitor the position of the door blade, the door is equipped with two PL e/Category 4 Eden sensors (contact
free) in both sides of its frame. When the door is closed the Eden sensors are actuated and the machine is ready to
be restarted. When the door starts to open, a stop signal is sent to the machine.
As the door has Eden sensors on both sides, this prevents the door being lifted or pushed to one side without a
stop signal being given to the machine.
To protect personnel from being injured by the door it is equipped with a contact strip on the bottom beam profile. If
the door hits a person the contact strip will be actuated, and the control system will reverse the door to its fully open
position.
