14.1 Releaseoftrappedpersons
Described here is how persons can be freed if trapped in the car.
ATTENTION:
Upon actuation of the override, a safety system of the lift system is disabled. From this time on, the safety of the
enclosed persons is the responsibility of the installation operator.

3
Move the car to the next floor by either releasing the brake or by using auxiliary mode control.
4
Allow the passengers to exit.
5
Switch the main switch back on again.
For other escape facilities, see the respective lift system.
14.2 Calculatingthestoppingdistance
During commissioning, it is to be verified by means of a calculation that the maximum stopping distance corres-
ponds to the values required by the standard. This verification is to be performed separately for both directions.
The calculation is performed with the aid of the formulas given below. The values in the fields with a thick border
must be determined before starting the calculation. Please note that it may be necessary to convert the values
to the correct units.
14.2.1Downwardstoppingdistance
A: Initial situation (end of the door zone):
For a lift without door zones, initial position x
A
=200mm is to be used.

The "downward acceleration" a
A
= g specified here is the worst case. For individual cases, a lower value,
which shortens the stopping distance accordingly, can be used following consultation with the tester on site.
B: Reaction time of the safety device and of the solenoid:
The safety device and the solenoid require a certain amount of time before they detect the error state and can
react to it.
