Elevator Control System Functional Description

Standard Functions

1.

Full collective control

When in automatic or attendant mode, the lift runs in respond to the car call and at the same time, automatically responds to the up/down hall call signal, i.e., a passenger can call the car by registering up/down call signal at any landing.

2.

Inspection mode

This function is for inspection or commissioning of elevator. While in permitted running conditions, pressing the up/down button can run the elevator in up/down direction point by point in inspection speed. Pressing the button continuously can keep the elevator running and releasing the button will stop running the elevator.

3.

Slow speed rescue operation

Whilst the elevator is not in inspection mode and not in the landing zone. Provided that it meets the safety requirements of starting, the elevator will run to the landing zone in slow speed, open the door and release the passengers.

4.

Testing mode

This is a function designed for testing or measuring the performance of a new lift. By setting a given parameter on the main board to testing mode, the elevator will run automatically. Both the total number of trips and the interval between the trips can be determined by parameter setting.

5.

Clock control

With the built-in real time clock in the system, the actual time of a breakdown can be recorded in the fault record. In addition, it can also be used to initiate the required functions precisely at a specified time

6.

Automatic control for door open holding time

Whilst not in attendant mode, the elevator lands and the door opens, after that, the door will keep opening for a certain time and then closes automatically. The door open holding time can be set in the parameters for both cases when there is no call at this floor or when there is a call at this floor.

7.

Door open at local landing

When the call button at this landing is pressed down, the car door opens automatically. If keeps pressing on the button, the door remains open.

8.

Advanced door closing by door close button

When in automatic mode and the door is open, the door can be closed immediately by pressing the door close button, and door is closed in advance.

9.

Door opening by door open button

When the car stops within the door zone, a passenger in the car can open a closed door or make a closing door re-opens by pressing on the door open button.

10.

Door re-open

If the door has been closed for 15 seconds but the door lock is not yet closed, the lift will return to door –opening status.

11.

Landing at changed destination

If the door has been open for 15 seconds but the door open limit switch is still not yet activated, the door will close and the lift will travel to the next destination after the door is closed.

12.

False car call cancelling

If the passenger finds that he has registered a wrong car call, by double clicking the same car call button, the call will be cancelled.

13.

Automatic car call cancelling in reverse direction

If the car reaches the terminal floors and is going to reverse its direction, all the car calls registered afterwards will be cancelled.

14.

Direct landing

With analogue speed given the elevator decelerates according to the principle of “Distance”, no creeping when landing.

15.

Full load by pass

In automatic and without attendant control mode, when the elevator is fully loaded (80% of rating load in general), the elevator will not respond to the hall calls passed and only respond to the dictated command signal.

16.

Automatic car fan and lighting timer

If a lift stands without any hall call and command signal for more than 5 minutes (default value, adjustable parameter), the car lighting and fan will automatically cutoff, and will resume once receiving a hall call or command signal.

17.

Automatic homing to main floor

In without attendant control mode, if there is no hall call and command signal and the automatic homing function is valid, the elevator will return to the main floor automatically after a specified period of time( such time can be set in the parameters)

18.

LCD interface operator

The LCD display and operating panel is mounted on the main board, it can display lift rated speed, direction, status and lift running speed, and can also display elevator fault records.

19.

Analogue speed given

The speed curve is be self-generated by analogue speed curve given, using the principle of “Distance” for deceleration, direct landing is made possible, elevator running efficiency is enhanced.

20.

Digital speed given

In case the inverter has no analogue-control port, digital muti-section speed control can be chosen, strong anti-interference ability.

21.

Fault history record

Up to 20 latest fault records can be stored, which includes time, floor number and fault code.

22.

Self-learning of shaft data

This is a self learning process before the formal running of the elevator, during this simple process the shaft data (floor position, deceleration switch position, protection switch position etc.) will be learnt and saved.

23.

Arbitrary setting of service floors

Using the hand held operator, the service floors of an elevator can be set arbitrarily.

24.

Setting of floor display characters

Using the hand held operator, the character used to indicate every floor can be set arbitrarily, e.g., indicating “B’ for basement floor.

25.

Attendant control

Attendant control can be activated through the toggle switch in the COP. In this mode, the elevator does not have automatic door closing function, door closing is made by continuously pressing the door close button by the attendant. Also, the attendant can choose the direction of traveling and by-passing.

26.

Independent drive

In this mode, the elevator will not respond to any hall calls, and will not close the door automatically. Others are similar to attendant control.

27.

Dot matrix floor indicator

Dot matrix floor indicator is used for both lift car and hall indicators. Withthe characteristic ofrichness character, dynamic display, beautiful font style, etc.

28.

Scrolling display for running direction

The direction of travel is displayed with scrolling dot matrix both for lift car and hall indicators.

29

Automatic correction for landing position signals

During the operation of elevator, the system will correct the landing position data of the elevator at every terminal switch and leveling switch obtained from self-learning.

30.

Car locking

In automatic mode and when car locking switch is activated, all registered hall calls will be cancelled. The elevator still runs normally but it only responds to car commands until no further command is registered. The elevator will return to the main floor, car fan and lighting will be switched off after the door is opened automatically, and the door will be automatically closed after 10 seconds, and the elevator will stop running. The elevator will start running normally when the car door locking switch is being reset.

31.

Protection from door opening beyond the door zone

For the sake of safety, the doors cannot be opened outside the door zone.

32.

Protection by door light curtain

Whenever any object appears or stays between the closing door panels, the protection device will be activated and the elevator will reopen the door. However, such protection device will not be activated during the fireman operation.

33.

Protection from overload

When the overload switch is activated, the door will not close and the buzzer sounds.

34.

Anti-nuisance

If the system is equipped with a light-load switch, when it activates, and the number of car calls exceed the preset value (adjusting parameter), all car calls will be cancelled by the system.

35.

Protection from running in reverse direction

If the system detects that the car running direction is not coincident with the commanded direction in 3 consecutive seconds, the elevator will stop immediately and fault will be alarmed.

36.

Protection from rope slipping (Running time limit device)

During the normal running of the elevator (except for in inspection mode), if it has run consecutively for an interval that exceeds the restricted interval preset (maximum 45 seconds), and no leveling switch has been activated during this interval, the system will consider this is a fault due to rope slipping and as a result, it will stop the lift car from running. It will resume into normal running until resetting after power cut-off or changing into inspection mode.

37.

Protection from car sliding

If the system detects a feedback pulse for consecutively 3 seconds after the car lands, it will consider this is a fault due to car sliding and the fault will be alarmed, and will prevent the lift from running when a fault occurs.

38.

Protection from car overrun

Upper/Lower terminal decelerating switches, terminal limit switches and terminal final limit switches are installed to prevent the lift from overrunning.

39.

Safety contactors and relays monitoring

The system detects the status of all relays and contactors to ensure that they function reliably; otherwise, the system will stop the lift from running until resetting after power cut-off.

40.

Speed regulator fault protection

Once the system detects a fault signal from the speed regulator, it will emergent stop the lift, and will prevent the lift from running when a fault occurs.

41.

Main control WDT protection

The main board is equipped a WDT protection, if a CPU fault or a program fault is detected, the WDT circuit will force all output ports of the main control to OFF, and resets the CPU.
