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.
Fireghter operation
After the elevator enters the reghter operation 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.
Security oor
After the security oor function is enabled, the security oor is used at
10:00 p.m. to 6:00 a.m, and the elevator runs to the security oor rst
every time, stops and opens the door, and then runs to the destination
oor.
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.
Forced stop at oor When a oor is specied as the forced stop oor, the elevator stops at
this oor at each time running.
Operation rights
restricted based on
levels
The system provides multiple levels of security passwords, each
corresponding to different operation rights, improving elevator operation
security.
Troubleshooting
based on fault level
Faults are classied into different levels based on the severity. Different
levels of faults are rectied using different methods.
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.
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, EPS 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.
Running direction
self-identication at
power failure
When the power supply is interrupted, the system can automatically
identify the current car load and determine the running direction.
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.
