Fire Emergency and Security Functions
Returning to
base oor at re
emergency
After receiving a re emergency signal, the elevator
does not respond to any call but directly runs to the re
emergency oor and waits.
F6-03 (Fire
emergency oor)
Fireghter running
After the elevator enters the reghter running mode,
door open/close is implemented by the jog operation
(optional) by using the door open and close buttons
rather than automatically. In addition, the elevator
responds to only car calls and only one call can be
registered once.
F6-68 (Fire
emergency
function selection)
Elevator lock
In automatic running state, when the elevator lock
switch acts or the set elevator time is reached, the
elevator cancels all registered calls, returns to the
elevator lock oor, stops running, and turns off the
lamp and fan in the car.
F6-04 (Elevator
lock oor)
Troubleshooting
based on fault level
Faults are classied into different levels based on the
severity. Different levels of faults are rectied using
different methods.
Refer to Chapter
8
Runaway
prevention
The system detects the running state of the elevator in
real time. If the elevator speed exceeds the limit, the
system immediately stops running of the elevator.

Automatic
identication of
power failure
The system automatically identies power failure and
outputs the relay signal for emergency evacuation
automatic switchover to implement emergency
evacuation at power failure.
Y0 especially
used for
emergency
evacuation
switchover
Automatic running
mode switchover at
power failure
For the synchronous motor, when the power supply
is interrupted, the system can perform automatic
switchover between shorting stator braking mode and
controller drive mode, implementing quick and stable
self-rescue.
Shorting stator braking mode: Upon power failure,
UPS is used, the motor stator is shorted, and the brake
is automatically released, making the car move slowly
under the effect of the weighing difference between the
car and the counterweight.
F6-69
(Emergency
evacuation
function selection)
Running direction
identication at
power failure
When the power supply is interrupted, the system
can automatically identify the current car load and
determine the running direction.
F6-69
(Emergency
evacuation
function selection)
Base oor
verication
After detecting a position abnormality, the system runs
the elevator to each oor until reaching the terminal
oor for verication, guaranteeing system security.
-
Passenger
unloading rst upon
fault
The system automatically determines the fault level. If
the safety running conditions are met, the elevator rst
runs to the leveling position to unload passengers.
-
Interference degree
judgment
The system judges the degree of communication
interference.
