7.2. Emergency evacuation
DANGER
f
All actions for evacuation in case of emergency have to be done by qualified service personnel.
f
When attempting an evacuation, the car may not move even when the brakes are released, as a result of load
compensation between the car and the counterweight. In this case, add weight to the car by suitable means, e.g.
sand bags, or use the mechanical return motion device.
Manually operated evacuation in case of emergency
•
The brakes (3) can be released remotely by hand
using a lever block (1) and Bowden cables (2).
•
The installation and operation of this device is
described in section 12.4. “Remote brake control
by Bowden cable”. The lever block and the Bowden
cables are available separately.
•
If the brakes are released manually, the lift car
moves in the direction of the higher weight.
•
The motor winding should be short-circuited using
the motor contactors. This prevents the lift from
accelerating in an uncontrolled manner, since
the short-circuiting produces a speed-dependent
braking torque.
•
It may transpire that the braking torque provided by
short-circuiting the motor is insufficient to restrict
the speed of the lift. You should therefore keep a
close eye on the car speed during evacuation and
halt the evacuation if necessary.

Remote brake control
by Bowden cable
•
Stop the manual release of the brake when the car has reached the next floor. The trapped passengers can now be
evacuated.
WARNING
f
After releasing the brakes manually, check that
the manual release levers (4) return to their initial
position.

Emergency evacuation by electrical means
•
Alternatively, the brakes can be released electrically in an emergency, using the mains or a UPS.
•
When resorting to this method of emergency evacuation, refer to the relevant instructions in the operating manual
regarding the control system, the inverter and the evacuation unit (with UPS).
