Parallel AC380 Volt Elevator Control System for Cargo / Observation Lifts ，NV3000 Series Elevator Integrated Controller

Features:

Floor Height Data Automatic Correction

Each time the elevator passes through the levelling position, system will auto correct the error position with respect to the shaft parameter self-learn position data base to maintain consistent ride comfort.

Elevator Position Auto Calibration

Each time the elevator enters the terminal floor zone, system will self-calibrate the position counter with respect to the 1 st slowdown limit switch so that elevator over travel operation will be eliminated.

Preset-able Hall Display

Allows user to preset every floor display with additional number (0-9) or character (A-Z) for non-standard display.

Cancellation Of Unintended Car Call

Passenger needs to press the unintended floor button twice to cancel the false call.

Reverse Command Cancellation

When elevator travel to the terminal top or bottom floor, system cancel all the car calls registered for the reverse direction operation.

Full Load By-Pass

When the elevator load exceeds the full-load set value, (generally > 80% load capacity) the elevator will not respond to hall calls when passing floors. However, during this event hall calls can still be registered; they will be serviced on the travel (simplex), or by other elevator service (duplex or group control)

Anti-Nuisance Function

System identifies the number of passengers in the car and automatically compares the number of passengers with the number of instructions registered in the car. If an excessive number of calls are registered, then the system considers it is nuisance status and cancels all the car calls. The passengers need to re-register the desired calls again.

Overload Protection

When the elevator is at stationary and the load capacity excesses the rate load capacity, buzzer will sound together with the overload light on. Elevator will halt until till overload alarm is trigger off.

Duplex Control

Its need only 3 wires to setup without the needs of group controller board.

Group Control

Group control with less than 8 elevators is based on fuzzy logic control theory

Independent Mode

Elevator does not respond to any hall calls and closes the door automatically.

Reversal Running Protection

Systems continuously monitor the encoder direction via ‘AB’ phase. System will stop immediately when wrong direction is detected, brake will be applied and system will trip on level 5 fault code.

Anti-Slip Protection

Systems continuously monitor the speed of the elevator via ‘AB’ phase. System will stop immediately when no speed feedback from the cage, brake will be applied and system will trip on level 5 fault code.

UP/DOWN Over-Speed Protection

The over-speed detector gives an assurance that the speed of car cannot exceed the range of secure speed, thereby guaranteeing the safety of both passengers and cargo.

Output Contactor Monitoring

By monitoring the drive output current state, system can determine whether the output contactor circuit is abnormal before release the motor’s brake.

Encoder Fault Protection

System uses a high-speed encoder for close-loop vector control. If the encoder fails, the system stops automatically to prevent a runaway failure.

Optimum Velocity Profile Generator

The lift controller will optimise the velocity profile based on the desired travel distance and auto- generate velocity profile to achieve direct-to-floor landing.

Time-Sharing & Peak Service

Flexible setting of the time-sharing service time period and the corresponding time-sharing service floors.
