Our freight elevator uses microcomputers to regulate the variable voltage variable frequency control technology and has advanced international technology.
1elevator variable frequency control
By adjusting the voltage and frequency of the motor by the frequency converter, the speed of the motor can be controlled freely and the comfort of the elevator can be improved. At the same time, it can save the power of the motor.
2 vector control
Used for servo tracking motor instantaneous speed, so that motor operation is more stable.
3full collective and selective control
In the automatic state or the driver's state, the elevator calls the button signal at the same time in response to the instruction signal in the sedan chair. All passengers in the floor can call up the elevator by calling up and down summon signals.
4 maintenance and operation
This is the operation function used in the maintenance or commissioning of the elevator. When it is in line with the operating conditions, the up / down button can make the elevator run on / down at the speed point of maintenance.Press the button continuously to keep the elevator running and release the button.
5 slow self rescue operation
When the elevator is in a non overhaul condition, it is not stopped in the flat area.At this point, as long as it meets the safety requirements of starting, the elevator will automatically run slowly to the level area and open the door.
6 clock control
There is a real time clock in the system, so the exact time of each failure can be recorded when fault records are taken.In addition, you can also determine exactly when to open what functions.
7 keep automatic control of door opening time
Without the driver running, the elevator will automatically shut down after several hours of automatic delay.If there is no call signal, the delay time is 2.5 seconds. If there is a call signal, the delay time is 4 seconds.This delay can be set in the parameters.
8 door opening from outside hall of this floor
If the call button is pressed, the door opens automatically.If the button is pressed and hold, the door is open.
9 advanced door closing for closing door button
In automatic condition, the door can be closed immediately after closing the door, closing the door ahead of time.
10 door opening for door opening button
When the elevator stops in the gate area, it can press the door button in the car to reopen the door which has been closed or not closed.
11 repeated door opening
If the elevator keeps closing for 8 seconds, the door lock will not be closed until the elevator is turned into the open door.
12 docking at exchange stop
If the elevator continues to open for 8 seconds, the door opening limit has not yet been moved.The elevator will turn off the door.And after the door is closed, respond to the next call and instruction.
13 error instruction cancellation
When the passenger presses the command button, it is found to be incompatible with the actual requirement, and the signal of the registration is cancelled after the instructions are registered with the button of 2 error instructions.
14 automactic cancellation instruction when reverse direction happened
When the elevator reaches the farthest station, it will reverse all original registration instructions.
15 direct docking
When the system adopts analog control, the elevator decelerate completely according to the principle of distance, and there is no crawling when leveling.
16 full load bypass
In the case of automatic no driver running, when the car is full loaded (usually 80% of the rated load), the elevator does not respond to the summoning signal and only responds to the instruction signal.
17 automatic power off for lighting,fan in the car when the elevator is waiting
If the elevator has no instruction and call registration for more than 3 minutes, the cabin lights and fans will be automatically cut off.But after receiving the instruction or calling the signal, it will automatically reactivate the power and put it into operation.
18 automatic return to base station
When there is no driver operation, if the automatic base station function is set, the elevator is automatically returned to the base station after a certain time (time can be set by parameter setting) when there is no instruction and call.
19 liquid crystal display interface operation
The main board is equipped with liquid crystal display and operation panel, which can show the speed, direction, state of elevator and the speed of elevator operation. It can also inquire the fault record of elevator and so on.
20 simulated velocity given
By selecting the analog speed curve, the speed curve can be generated by itself, and the distance principle is used to decelerate, so as to realize direct stopping and improve the efficiency of the elevator operation.
21 fault history record
20 recent faults can be recorded, including time, floor and code.
22Data self learning of shaft and floor
Before the official operation of the elevator, the well track learning function of the starting system is used to learn the various data in the well path (layer height, protection switch position, deceleration switch position, etc.), and keep these running data permanently.
23 arbitrary setting of the service floor
Through hand-held operators, we can set up any elevators to which stations and which stations do not stop.
24Arbitrary setting of display characters in many floors
The characters displayed on each floor can be set arbitrarily by hand-held manipulator, such as setting up the first floor display, etc.
The driver's operation can be selected through the toggle switch of the control box.When the driver operates, the elevator does not have the function of automatic closing, and the door of the elevator is carried out under the condition that the driver keeps pressing the shutter button.At the same time, it also has the driver to select directional and push buttons.There is no difference between other functions and no driver operation.
26scrolling display of running direction
The floor monitors in the hall and the sedan show the direction of operation when the elevator is running.
27Automatic correction of position signal of floor
When the system runs, the position signal of the elevator's position is corrected at each terminal switch action point and the flat layer switch action point of each floor.
28 lock elevator service
After automatic operation, the lock ladder switch is positioned, eliminating all call registration, the elevator is still operating normally, only responds to the car instruction until no instruction is registered.Then return to the base station, automatically open the door, close the car's interior lighting and fans, light the door opening button, and automatically close the door after 10 seconds of delay, then stop the elevator running.When the lock ladder switch is reset, the elevator starts working again.
29 infrared curtain protection
Each elevator is equipped with a door light screen protection device.When there is something blocking in the middle of the two car door, the door curtain will protect the elevator and the elevator will open.But the door curtain protection does not work in the fire control operation.
30 overload protection measures
When the overload switch moves, the elevator does not close and the buzzer rings.
31 reverse operation protection
When the system detected the direction of the elevator running continuously for 3 seconds is inconsistent with the direction of the instruction, it will immediately stop the emergency and alarm.
32 anti-skidding protection
In the non maintenance state, during the operation of the elevator, if the time limit of the limiter is running continuously (maximum 45 seconds), there is no horizontal switch action, and the system considers that the wire rope skidding fault is detected.Therefore, we will stop the operation of the car until the power is reset or turn to the maintenance state before it can resume normal operation.
33 car slipping prevention
The system detects that when the elevator stops the ladder, the feedback pulse is generated for 3 seconds in a row, and the elevator is judged to be slipped, so the alarm is broken and the elevator is prevented from running when there is a failure.
34 anti terminal overtravel protection
The upper and lower terminals of the elevator are equipped with terminal deceleration switches, terminal limit switches and terminal limit switches to ensure that the elevator will not travel further.
35 fire emergency return operation
When a fire is encountered, when the fire is returned to the switch position, the elevator immediately eliminates all instructions and calls, runs to the fire station in the fastest way, and opens the door to stop the ladder.
When a fire is encountered, when the fireman's operation switch is placed, the elevator immediately eliminates all instructions and calls to return to the fire station, and then goes into the firefighter operation mode.In the firefighters' operation mode, there is no automatic door closing action. Only by opening and closing the door button, point operation can cause the door to close.The elevator only responds to the instructions inside the car and eliminates all registered instructions after arrival.Only when the elevator opens and stops at the base station, will the two switches be reset before the elevator can return to normal operation.
37 arrival gong
When the elevator decelerates the flat layer, the ringing will be mounted on the top or bottom of the sedan chair and down to the station clock to remind the passengers and the waiting ladder passengers in the sedan floor to be in the flat and immediately to the station.
When the lift is cut off, the emergency lights in the car will automatically light up.In order to prevent fear of rescue trapped personnel in the elevator.
In the car, computer room, car top, bottom pit and duty room, there is a private telephone.When the elevator is overhauled or fails, it can be checked or rescued by telephone.This device can be used even in the state of power outage.
40 bells alarm
When the elevator fails and the duty room is unmanned, the trapped personnel can press the alarm button, and the alarm bell in the well will send out a high decibels of sound to notify the external rescue.
