What is the fault of the Xizi Otis elevator upward reset

How to check for common hardware failures.

For the soft fault of the computer, it can be solved by analyzing the fault phenomenon, reinstalling the system, replacing the software, modifying the software program, or removing the computer virus. For hard faults, it is necessary to check and eliminate them step by step according to the inspection principle, and the following ten inspection and judgment methods for hard faults are introduced

1.Plugging and unplugging method.

The "plug-in method" is a method of "unplugging" or "plugging" a plug-in to look for faults. For example, if the machine has a "deadlock" phenomenon, this method is used to pull out the plug-in board piece by piece, and if the machine returns to normal, it means that the fault is on the board.

2.Substitution method.

The "replacement method" is to replace the suspected problematic device with the one that has been determined to be the best, and gradually narrow down the search.

3.Comparative Law.

The "comparison method" is to compare the correct characteristics (waveform or voltage) with the characteristics (waveform or voltage) of the faulty machine to see which component's waveform or voltage does not match, and measure it pole-by-pole according to the logic circuit diagram, so that the signal is detected point by point in the direction of the source pursued, and the fault location is determined after analysis.

4.Measurement method.

The "measurement method", also known as the "static measurement method", is an effective method to try to suspend the computer in a specific state, measure the level of each point required with a multimeter according to the logic diagram, and analyze and judge the fault.

5.Heating method.

The "heating method" is a method to artificially raise the ambient temperature and accelerate the "death" of some components with poor high temperature parameters to find faults.

6.Percussion.

The operation of the machine is good or bad, which may be caused by the false soldering or poor contact of the pins of the components and components, or the increase of the resistance of the metal through hole. In this case, it is much easier to use the percussion method to check the circuit board by gently tapping the board with a rubber hammer and then checking it again.

7.Partition method.

The segmentation method is a method of "splitting" the fault, gradually shrinking the board, narrowing it to a certain line, and then to a certain point.

8.Direct observation.

The true observation method is to use human senses to directly observe sparks, abnormal sounds, overheating, scorching and other phenomena to determine the power supply short circuit, overcurrent, overvoltage, loose plug-ins, corrosion damage and other obvious faults.

9.Isolated compression method.

That is, according to the phenomenon of the fault and the hardware parts, some information about the relevant parts is temporarily disconnected or the original data is simplified to reduce the search range.

10.Procedural testing method.

That is, the use of boot self-test program, advanced special diagnostic program to help find the cause of the fault, the diagnostic program in the form of a menu to provide a number of hard drive, floppy drive, CD-ROM, printer and other detection, if the hardware failure, the display of error, sound to obtain the fault point and its cause.

When the hoistway data is abnormal, go to the top floor to correct the floor data.

That's when the next strong reduction action is reset.

Summary. Hello, this is the fault of the brake switch, just adjust the switch, it may be caused by the compression stroke is not enough and the switch can not operate normally.

Hello, this is the fault of the brake switch, just adjust the switch, it may be caused by the compression stroke is not enough and the switch can not operate normally.

Summary. As the name suggests, emergency electric is used in an emergency, and the emergency electric in the elevator is a kind of maintenance operation, but when entering the maintenance mode, a part of the safety loop will be shorted at the same time, of course, it is only a specific part of the safety circuit, and it will generally be shorted up and down the limit switch, buffer switch, safety gear switch, and speed limiter switch, which is generally installed in the control cabinet of the machine room for easy maintenance. When the maintenance switch in other positions is in the maintenance state, it will automatically exit the emergency electric mode.

Xizi Otis elevator can go to the slow train for maintenance, and the normal elevator will also level the floor, that is, the normal elevator does not take the elevator, and the internal call is displayed.

Hello. The reason why the elevator can be overhauled is that the maintenance box line is loose. Find the two male and female plugs of the normal line according to the normal and maintenance switch wires on the maintenance box, and unplug the normal two wires. Maintenance and normal can be switched, with indicator light display.

Xizi Otis elevator can go to the slow car for maintenance, and the normal elevator will also level the floor, that is, the normal elevator does not take the elevator, and the internal call shows emergency electric. Fire protection and weighing switches.

Seen. The elevator display is normal.

Two bars. The elevator has two horizontal bars, which means that the elevator is in a state of non-normal operation or cut off service, such as the elevator has started the protection function (crash or failure), the elevator has been overhauled, etc., and the display will have two horizontal bars.

Fault protection, you can power off first and then send power to reset.

The internal call shows the emergency electric.

As the name suggests, emergency electric is used in an emergency, and the emergency electric in the elevator is a kind of maintenance operation, but when entering the maintenance mode, a part of the safety loop will be shorted at the same time, of course, it is only a specific part of the safety circuit, and it will generally be shorted up and down the limit switch, buffer switch, safety gear switch, and speed limiter switch, which is generally installed in the control cabinet of the machine room for easy maintenance. When the maintenance switch in other positions is in the maintenance state, it will automatically exit the emergency electric mode.

Otis 300vf elevator maintenance internal call will not appear emergency electric.

Hit the emergency electric elevator will not run.

This elevator does not have emergency electric and is a vertical elevator not.

Summary. Hello, 1. Please check whether there is a reset button on the panel of the elevator, if there is, please press the reset button, the elevator will automatically reset; 2. If there is no reset button, you can disconnect the power supply from the control panel of the elevator, then wait for 2-3 minutes, and then power on again to reset; 3. If the above methods cannot be reset, you can contact the official customer service of Xizixiao Elevator and be operated by professional and technical personnel.

The elevator cannot be reset, and the button cannot be found.

1. Please check whether there is a button on the panel of the elevator to re-raise the state position, if there is, please press the reset button, and the elevator will automatically reset; 2. If there is no reset button, you can disconnect the power supply from the control panel of the elevator, then wait for 2-3 minutes, and then power on again to reset; 3. If the above methods cannot be reset, you can contact the official customer service of Xizixiao Elevator and be operated by professional and technical personnel.

You try the above methods dear.

The elevator can go up but not down.

According to the fault phenomenon, this problem is that the inverter fault leads to sleepy excavation, the elevator gives the slow train signal after the brake opens, but the inverter does not output, just like the direct macro core is connected to the manual release of the brake, giving people the illusion that the maintenance is slow up and down are on the up, in fact, careful observation can find the problem, the speed of the slow car ruler is relatively slow, and there is a unique electromagnetic sound when the inverter is working, if it is a slippery car, the speed is very fast, and it is also dangerous, so it is necessary to pay attention.

Okay, I'll try. Hmmm.

There may be a variety of reasons for the failure of the OPB instruction of Xizi Otis elevator, and some possible fault reasons are listed below for reference:

1.Power issues: OPB instructions are provided by the control system, and if the power supply is unstable or interrupted, it can cause OPB command failure.

2.Communication line problem: OPB command needs to be transmitted to the elevator control system through the communication line, please check whether the communication line is connected normally, whether it is damaged by the construction personnel, etc.

3.Control system configuration problems: OPB instructions are related to the parameter settings and configuration of the elevator control system, if the system parameters are misconfigured or mismatched, it may lead to the failure of OPB instructions.

4.Contact problem: Please first check whether the connectors, terminals, relays, control boards and other components related to the OPB command in the elevator control system are in poor contact, and whether there are loose and other faults.

5.OPB button failure: OPB command needs to be provided to the elevator control system through the OPB button, if the OPB button fails, such as key failure, connection line disconnection, etc., it may lead to OPB command failure.

If you are unable to solve the OPB command failure by yourself, it is recommended to consult the elevator manufacturer or the technician of the maintenance company for assistance. During the troubleshooting, in order to ensure the safety of passengers and staff, it is recommended to remind the elevator to stop using the noise through signs and physical barriers to prevent accidents.
