Introduction
Function Description Remarks
Floor position
intelligent correction
Every time the elevator runs to the terminal oor, the system
automatically checks and corrects the car position information
based on slow-down switch 1, and eliminates over travel
top terminal or bottom terminal with use of the slow-down
switches.
-
Dual-speed for
inspection
Considering inaccurate running control at high inspection
speed but long running time at low inspection speed, the
system provides the dual-speed curve for inspection, which
greatly improves the efciency at inspection.
-
Test running
The test running includes the fatigue test of a new elevator,
car call oor test, hall call test, and tests such as hall call
response forbidden, door open/close forbidden, terminal oor
limit switch shielded, and overload signal shielded.

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 and F8-12 (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.
F6-44
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.
F6-13
Elevator lock
In automatic running state, when the elevator lock switch acts
or the set elevator time is reached, the elevator returns to
the elevator lock oor after responding to all car calls, 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.
-
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.
Y6 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.

evacuation function

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.
