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.

Fireghter operation

After the elevator enters the reghter 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 specied 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 classied into different levels based on the severity. Different
levels of faults are rectied 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

identication of

power failure

The system automatically identies 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 self­rescue.

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-identication 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
verication

After detecting a position abnormality, the system runs the elevator to

each oor until reaching the terminal oor for verication, 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.

NICE7000 User Manual Introduction

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

identication

The system detects the bus voltage and automatically adjusts the running

speed of the elevator to adapt to the situation of insufcient power from

power supply (such as EPS).

Intelligent distribution
of emergency power
supply (EPS)

This function is optional for the group control elevator system congured

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 insufcient.

Note: This function is not the standard function. If it is used, software

modication 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.

Introduction NICE7000 User Manual

- 10 -

Full-load indication

When the elevator is full-loaded, a full-load indication is displayed on the

HCBs and the elevator directly runs to the desired oors.

Interface for
intelligent residential
management

The system provides an interface for intelligent residential management
to perform remote monitoring on the state of elevators in the residential
district.

Energy-saving Functions
Car energy-saving

If there is no running command within the set time, the system
automatically cuts off the power supply to the lamp and fan in the car.

Energy-saving
running with standby
power supply

When the normal power supply is interrupted and the EPS is used, the
system reduces the running speed of the elevator in the prerequisite of
guaranteeing the smooth running curve.

Arrival gong disabled
at night

Within the set time period, the arrival gong is disabled.

Energy-saving of idle
door machine

After the car lamp is turned off, the system does not output the door close
command, which reduces power consumption of the door machine.

4. Optional functions

Function Description Remark

Micro-leveling

After landing at a oor, the elevator may move upward or

downward due to the load change and the car door is not
aligned with the ground, which is inconvenient for in and out
of passengers and goods. In this case, the system allows the
elevator to run to the leveling position in the door open state
at the leveling speed.

MCTC-SCB
required

Power failure
emergency
evacuation

For the elevator congured with EPS, the system uses the

EPS to implement low-speed self-rescue in the case of
power failure.

EPS required

Onsite
commissioning

The system can control and monitor running of elevators by
using the NEMS software.

NEMS software
required

Residential
monitoring

The control system can be connected to the terminal in the
monitoring room. By using the NEMS software, you can view

the oor position, running direction, and fault state of the

elevator.

NEMS,
accessories,
and MCTC-MIB
required

Door pre-open

During normal stop, when the elevator speed is smaller than

0.2 m/s and the door zone signal is active, the system shorts
the door lock by means of the shorting door lock circuit
contactor and outputs the door open signal, implementing

door pre-open. This improves the elevator use efciency.

During
maintenance

DANGER

•

Do not repair or maintain the controller at power-on. Failure to
comply will result in electric shock.

•

Repair or maintain the controller when its voltage is lower than
36 VAC, about 10 minutes after the controller is powered off.
Otherwise, the residual voltage in the capacitor may result in
personal injury.

•

Do not allow unqualied personnel to repair or maintain the

controller. Failure to comply will result in personal injury or
damage to the controller.

•

Set the parameters again after the controller is replaced. All the
pluggable components must be plugged or removed only after
power-off.

1.2 General Precautions

1. Requirement on the residual current device (RCD)

The controller generates high leakage current during running, which ows through the

protective earthing conductor. Thus install a type- B RCD at primary side of the power
supply. When selecting the RCD, you should consider the transient and steady-state
leakage current to ground that may be generated at startup and during running of the

NICE7000 User Manual 1 Safety Information and Precautions

- 19 -

controller. You can select a specialized RCD with the function of suppressing high
harmonics or a general-purpose RCD with relatively large residual current.

2. Motor insulation test

Perform the insulation test when the motor is used for the rst time, or when it is reused

after being stored for a long time, or in a regular check-up, in order to prevent the
poor insulation of motor windings from damaging the controller. The motor must be
disconnected from the controller during the insulation test. A 500-V mega-Ohm meter is

recommended for the test. Ensure that the insulation resistance is not less than 5 MΩ.

3. Thermal protection of motor
If the rated capacity of the motor selected does not match that of the controller,

especially when the rated power of the controller is greater than that of the motor, adjust
the motor protection parameters on the operation panel of the controller or install a
thermal relay for the motor circuit for protection.

4. Motor heat and noise
The output of the controller is pulse width modulation (PWM) wave with certain harmonic

wave, and therefore, the motor temperature rise, noise, and vibration are slightly greater
than those at running with the mains frequency.

5. Voltage-sensitive device or capacitor on the output side of the controller
The controller outputs PWM waves, and therefore, do not install the capacitor for

improving power factor or lightning protection voltage-sensitive resistor on the output
side of the controller. Otherwise, the controller may suffer transient overcurrent or even
be damaged.

6. Switch (contactor) on the input and output sides of the controller
If a contactor is installed between the power supply and the input side of the controller,

DO NOT use it to start or stop the controller. However, if there is a need to use the
contactor to start or to stop the controller, make sure the time interval between switching
is at least one hour. If the interval between switching is shorter than one hour, this will
reduce the service life of the capacitor inside the controller.

If a switch such as contactor is installed between the output side of the controller
and the motor, operate the switch only when the controller has no output. Otherwise,
modules inside the controller may be damaged.

7. Use outside the rated voltage

The controller must not be used outside the allowable voltage range specied in this

manual. Otherwise, components inside the controller may be damaged. If required, use
a corresponding voltage step-up or step-down device.

8. Surge suppressor
The controller has a built-in voltage dependent resistor (VDR) for suppressing the surge

voltage generated when the inductive loads (electromagnetic contactor, electromagnetic
relay, solenoid valve, electromagnetic coil and electromagnetic brake) around the
controller are switched on or off. If the inductive loads generate very high surge voltage,
use a surge suppressor for the inductive load or use a surge suppressor together with a
diode..

Note

Do not connect the surge suppressor on the output side of the controller.

9. Altitude and de-rating
In places where the altitude is above 1000 m and the cooling effect reduces due to thin

air, it is necessary to de-rate the controller. Contact Monarch for technical support.

10. Special usage
If wiring that is not described in this manual, such as common DC bus is applied, contact

the agent or Monarch for technical support.

11. Disposal
The electrolytic capacitors on the main circuits and PCB may explode when they are

burnt. Poisonous gas is generated when the plastic parts are burnt. Treat them as
ordinary industrial waste.

NICE7000 User Manual 1 Safety Information and Precautions

- 21 -

12. Adaptable motor
The controller is adaptable to squirrel-cage asynchronous motor or AC PMSM. Select a

proper controller according to motor nameplate.

The default parameters congured inside the controller are squirrel-cage asynchronous

motor parameters. It is still necessary to perform motor auto-tuning or modify the
default values based on actual conditions. Otherwise, the running effect and protection
performance will be affected. For PMSM, motor auto-tuning must be performed.

13. Precautions on selecting residual-current circuit breaker (RCCB)
Tripping may be caused if an improper RCCB is selected when the controller drives

the motor. This is because the output wave of the controller has high harmonics and
the motor cable and the cable connecting the controller and the motor produce leakage
current, which is much larger than the current when the motor runs at the mains
frequency.

Thus, it is necessary to determine the proper RCCB sensitivity based on the general
leakage current of the cables and the motor. The leakage current is dependent on the
motor capacity, cable length, insulation class and wiring method. Generally, the leakage
current on the output side of the controller is three times of the current when the motor
runs at the mains frequency.
