12 Emergency evacuation
12.1 General information
• In the event of a mains failure, there is the possibility to carry out an emergency evacuation.
• By carrying out the emergency evacuation, the elevator cabin is driven into a
fl
oor or the ground
fl
oor.
12.2 Evacuation with 3-phase mains supply 3~400 VAC
12.2.1 General information
Requirements:
• For the emergency evacuation with 3-phase mains supply, the mains supply must provide the
following voltage to the frequency inverter:
–
3~400 VAC to feed L1, L2 and L3.
Information
An emergency evacuation with single-phase mains supply (AC) or with power supply by batteries (DC)
is not possible.
Characteristics of evacuation with 3-phase mains supply:
•
Evacuation in motoric and generatoric direction
•
Load-independent starts
•
Load-independent stopping
•
Flush stopping
Process for emergency evacuation with 1-phase voltage supply:
• The ZAdyn4B analyses the load ratio between the car and the counterweight for every journey
start.
• According to the load ratio, the ZAdyn4B transmits to the control, in which direction the evacuation
trip could be carried out more energy-ef
fi
ciently.
• The control system starts the evacuation trip by activating:
–
Controller enable
–
Direction default
–
Speed default
Size of the voltage supply
The required performance consists of the following:
Power consumption for ZAdyn4B electronics
+ Control systempower consumption
+ Electromechanical brakes power consumption
+ Other consumers (car light,
…
) power consumption
+ Motor power consumption during motoric operation with suf
fi
cient power
(ask motor manufacturer)
=
Real power [W]
Information
The shaft ef
fi
ciency has a decisive in
fl
uence on the required power of the three-phase mains supply.
