Interference degree
judgment
The system judges the degree of communication interference.
Earthquake
protection
When the earthquake detection device acts and inputs a signal to the
system, the elevator lands at the nearest oor and stops running. After
the earthquake signal becomes inactive and the fault is reset manually,
the elevator restores to normal running.
Current cancellation
in ramp mode
For the PMSM, after the elevator decelerates to stop, the holding current
of the motor is cancelled in ramp mode, preventing abnormal noise during
current cancellation.
Independent working
power supply
The NICE7000 system supports not only three-phase 380 VAC but also
single-phase 220 VAC to meet different applications of the power supply
system (such as 220 V UPS)
Automatic voltage
identication
The system detects the bus voltage and automatically adjusts the running
speed of the elevator to adapt to the situation of insufcient power from
power supply (such as EPS).
Intelligent distribution
of emergency power
supply (EPS)
This function is optional for the group control elevator system congured
with the EPS device. When the EPS is used, the system automatically
selects the elevator that is proper to run based on the preset parameters.
After the normal power supply restores, the system restores normal
running.
This function prevents power overload due to simultaneous running of
multiple elevators when the EPS is insufcient.
Note: This function is not the standard function. If it is used, software
modication and peripheral parts are required.
Parallel/Group Control and Other Functions
Parallel/Group
control
The system supports parallel/group control of two to eight elevators and
provides multiple scheduling algorithms to meet requirements of different
customers.
Dispersed waiting In parallel/group control, the elevators can wait at different oors.
Parallel/Group
control exit
If the parallel/group control exit switch of a certain elevator in a parallel/
group control system is valid or the time for exiting the parallel/group
control is reached, the elevator exits parallel/group control and runs
independently. This does not affect normal running of the parallel/group
control system.
Parallel/Group
control automatic
exit
If an elevator in the parallel/group control system cannot respond to
calls in time due to faults, the elevator automatically exits the parallel/
group control system and runs independently. This does not affect normal
running of the parallel/group control system.
Anti-nuisance
function
The system automatically judges the number of passengers in the car
and compares it with the number of registered car calls. If there are
excessive car calls, the system determines that it is nuisance and cancels
all car calls. In this case, passengers need to register correct car calls
again.
Prompt of non-door
zone stop
The system gives a prompt when the elevator stops at a non-door zone
area due to faults.
