Dual-speed for
inspection
Considering inaccurate running control at high inspection speed but
a long running time at low inspection speed, the system provides the
dual-speed curve for inspection, which greatly improves the efciency
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.
Fireghter running
After the elevator enters the reghter 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.
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.
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
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.
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
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 interference on the communication.
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 NICE3000new 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 emergency UPS).
Parallel/Group Control and Other Functions
Parallel control
The system supports parallel control of two elevators and provides
multiple scheduling algorithms to meet requirements of different
customers.
Dispersed waiting In parallel 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.
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.
Parameter copy You can conveniently upload and download parameters of the system
by using the LCD operator.

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 emergency power
supply 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

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 two 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.
WARNING
•Repair or maintenance of the controller may be performed
only by the center authorized by Monarch or qualied
personnel. Failure to comply will result in personal injury or
damage to the controller.
•Power supply must be cut off before repair or maintenance
of the controller.
CAUTION
•Set the parameters again after the controller is replaced. All
the pluggable components must be plugged or removed only
after power-off.
•Strictly obey the laws and regulations and repair and
maintain the elevator equipment periodically. Only timely
troubleshooting can ensure the safety of passengers.
Disposal
CAUTION
The packaging materials, screws and terminal blocks can be
re-used and it is suggested that you keep them well for future
use.
WARNING
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.
1.2 General Precautions
1. 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.
2. Thermal protection of the 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.

3. 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 power frequency (50 Hz).
4. 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.
5. Contactor on the input and output sides of the controller
When a contactor is installed between the input side of the controller and the power supply,
the controller must not be started or stopped by opening or closing the contactor. When a
contactor is installed between the output side of the controller and the motor, do not open or
close the contactor when the controller has output. Otherwise, modules inside the controller
may be damaged.
6. Use outside the rated voltage
The controller must not be used outside the allowable voltage range specified in this
manual. Otherwise, components inside the controller may be damaged. If required, use a
corresponding voltage step-up or step-down device.
7. 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 also use a diode.
Note
Do not connect the surge suppressor on the output side of the controller.
8. 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.
9. 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 configured 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.
10. 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 power frequency (50 Hz).
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 power
frequency (50 Hz).
1.3 Protective Functions
Adopting different protective functions for different levels of faults, the NICE3000new provides
the elevator running system with full abnormality protection. For detailed solutions to the
faults, see chapter 8.
Faults of the controller are classied as follows:
1. Speed abnormal
The controller monitors the encoder feedback speed and output torque. Once the
feedback speed exceeds the limit or the deviation between the torque limit and the
speed feedback is too large, the controller performs protection immediately, reports an
alarm and prohibits running.
2. Drive control abnormal
The related faults include drive overcurrent, overvoltage/undervoltage, power input/
output phase loss, overload, and storage abnormality. If such a fault occurs, the
controller performs protection immediately, stops output, applies the brake and prohibits
running.
3. Encoder abnormal
The related faults include encoder phase loss, direction reversing, wire-breaking, and
pulse interference. If such a fault occurs, the controller performs protection immediately
to avoid unexpected accidents. If pulse interference is large, the controller reports
an alarm immediately. If pulse interference is small, the controller performs position
correction every time it receives a leveling signal and clears the accumulative error.
4. Leveling sensor abnormal
The related faults include sensor failure or sensor stuck. The controller judges whether a
fault occurs based on the leveling signal change. If the leveling signal does not change
within the set time, the system reports an alarm.
5. Floor data abnormal
The system stores the oor information through the shaft auto-tuning. If the oor data
is abnormal, the system prompts the fault information at the rst-time running. During
actual running, the controller continuously compares position information input by DIs
with the stored oor data. If the deviation is large, the system reports an alarm.
