7.7 Brake Micro switch Test
Check the brake micro switches. The Normally Open and Normally Closed contacts of
the micro switches must be tested according to the safety system to be used and they
must be set to deactivate the lift in case of any failure.
7.8 Half Load Test
Ascend and descend the cabin with half load; the measured currents at ascent and descent
at the middle of the lift shaft shall not exceed 10 %.
7.9 Emergency Rescue
CAUTION!
The emergency rescue operation must be performed only by authorized
and qualified personnel.
INFORMATION
In case of motors without reducers, the manual rescue action requires a
very high force, since the force drop provided by the reducer is not
available.
For rescue operations in case of power failure, the automatic rescue control located on
the lift panel and carried out via the driver must be used. In this control system the driver
is supplied from a UPS or a battery to bring the cabin to the nearest floor at low speed
and to evacuate the passengers safely.
However, emergency rescue procedure must be performed if the above-mentioned
system fails or is out of operation. This procedure is carried out with a portable power
supply. The braking circuit connected to the motor phases must be activated and the
mechanical brake must be withdrawn by means of the power supply and the cabin is
moved toward the heavier direction in a controlled manner. During this procedure, the
cabin must move at low speed. If an uncontrolled acceleration is observed, the
mechanical brake must be activated immediately. During rescue procedure, the cabin
speed must not exceed be under 0,63 m/s. See Chapter 7.10.
Mechanical rescue procedure can only be carried out when automatic rescue and portable
power supply methods cannot be used and there is no other alternative for emergency
rescue.
