LIBERATION OF A PASSENGER
If the platform remains in an occupied state somewhere between the stops and all the above points
have been checked, the passenger can be released.
Passenger rescue may only be carried out by instructed persons. Two persons are
absolutely required!
8.1
Emergency driving mode
The emergency lowering mode can be used to move the platform up and down in the event of a
malfunction. Use the emergency lowering only if the control on the platform or the landing calls do
not work properly.
There is an increased risk of crushing. All safety devices are deactivated. This means that
no safety elements such as the safety bottom or the contact bar are functioning. Before
operating the emergency lowering, make sure that no persons are endangered and no
objects can be trapped under the platform.
The platform does
NOT
stop by itself in the stop area. One must bring the platform into
the stop with utmost care and stop the movement by releasing the drive button. At the
lower stop, avoid the platform touching down on the ground; the platform must stop
beforehand! At the upper stop, the platform must not be moved above the level of the
upper stop!
The emergency drive works electrically via the batteries and is located on the frame of the upper
swing door. A small metal cover must be unscrewed to operate the emergency drive buttons.
First move the platform up a few centimetres and then to the nearest stop, i.e. either down
or up. This can deactivate an accidentally triggered safety gear and is necessary in this case
to avoid damaging the chain.
The emergency drive mode brings the platform to the desired stop, but cannot unlock the manual or
automatic swing doors. The swing doors must therefore be unlocked manually (see the following
chapter).
