I hope mine is helpful to you, and if you have any questions, please keep asking.

It's not easy to answer the question, if it helps you, thank you.

The specific operation of Hitachi elevator overhaul is as follows: 1When many people cooperate with the maintenance of the elevator, they should concentrate their thoughts, respond to each other, and do a good job of cooperation.

2.If you want to use the triangular key to open the hall door, be sure to see the position of the car clearly, and don't assume that the elevator must be in a certain position. 3.

When opening the hall door and entering the car roof, the door can not be closed immediately, first of all, the maintenance switch is placed in the maintenance gear, press the emergency stop switch, turn on the car top light, and the hall door can be closed only after standing firmly on the car roof. 4.When going out of the car roof, first open the hall door, and then reset the car top maintenance switch, emergency stop switch, lighting switch, etc., and then close the hall door after arriving outside the hall.

If a person can operate the above switch while standing outside the hall, he should reset the above switch after standing outside the hall) 5.When the car is running, do not lean out of the bar. Do not work in the riding straddle.

7.When working in the pit, the safety switch of the pit maintenance box should be cut off. When climbing out of the pit, be sure to ensure that the hall door is open before the safety circuit of the pit can be connected, and then quickly climb out of the pit.

1. Fault **10 (50b 0n).

If these two ** are displayed on the elevator controller, first of all, we must carefully test the insulation of the elevator to ensure that the relay of 50b has been released normally when forced to pick-up. Secondly, we need to check whether the plugs of the MPU board and the FIO board are loose, and if they are loose, plug them back in.

Secondly, check whether the FI plug of the FIO board is plugged in tightly. If none of the above causes are the cause of the 0 failure, then we need to focus on the 50b and make sure that the contacts of the 50b relay are good and correct.

2. Fault **14 (double reference voltage abnormality).

Check the MPU board first, make sure that the FF board has been plugged in, if there is no problem, we will pull out the FF plug of the MPU board, and measure the voltage of FF20 FF23 and FF20 FF25 after power-on, and confirm that it belongs to the normal operation of the elevator.

3. Fault **17 (abnormal SDA communication of the car).

First of all, we need to check whether the SOC and MPU board have been lit up, and if so, use a voltage tester.

Measure the power supply voltage of Control-1, and its value should be about 12V if the normal land leakage is normal.

Then we can also find problems from the plug, such as whether the Y2 plug in the electrical box on the roof of the main car and in the machine room is normal, and whether the contact surface between it and the socket is clean. Secondly, check whether Y2-1 Y2-5 is disconnected, if it has been disconnected, connect it directly.

4. Fault **27 fault (repeated failure).

The countermeasure to this failure is to first carefully check the switch of the safety circuit to see if the contacts of the door lock switch are not in good contact.

5. Fault **35 ( on).

Confirm that the electrical wiring of the car door lock is not shorted; The car door lock is not forced to suck in. Confirm that the electrical wiring of the hall door lock is not shorted. Confirm that the 40D relay contacts are normal. Replace the FIO board and check if it is damaged.

1. **e01: indicates that the drive motor circuit is faulty. Causes of failures and corrective measures:

The drive speed control device is affected, the power control or safety device is affected, the fault is reset, the safety device is reset, and the wiring is checked and corrected. 2. **e02: indicates that the motor is overheated and faulty.

Cause of failure and corrective measures: There is a fault in the motor circuit, check the circuit, check the motor radiator, and whether there is dust in the motor shell? 3、**e03：

Indicates that the variable diggings are faulty. Cause of fault and corrective measures: check whether there is a short circuit or open circuit, check whether the current proportional coefficient and bus voltage in the drive speed control device are correct, and then replace the inverter parts or completely replace the inverter.

4. **e04: indicates that the laser is faulty. The cause of the failure and corrective measures are Zheng:

Check whether the power supply and the laser cable are connected normally, see if the power supply is disturbed, replace the laser cable, reset the mechanical equipment, reconnect the power supply and perform the detection procedure.

Summary. If Hitachi Elevator has a 093 fault, the elevator needs to be inspected and troubleshooting. Here are the possible workarounds:

If Hitachi Elevator has a 093 fault, the elevator needs to be inspected and troubleshooting. Here are the possible workarounds:

1.Check the control system of the elevator: 093 faults are usually related to the control system of the elevator. Check the elevator's control system, make sure that the elevator's controller and cables are well connected, and check that all electronic components of the controller and the elevator are working properly.

2.Check the telecommunication source of the elevator: the power supply of the elevator may lead to 093 failure. Check the power supply of the elevator to make sure all the power supplies are working properly, and check whether there is any damage to the power source line.

3.Check the lead machine room and car of the elevator: 093 faults may occur in the machine room and car of the elevator. Check the machine room and car of the elevator to ensure that all the equipment of the punching chain is working properly, and check whether the cables, electric gears and sensors of the elevator are faulty.

4.Check the door system of the elevator: The door system of the elevator may also cause the 093 Finger Barrier. Check the door system of the elevator to make sure all the doors are closed properly, and check that the access control spine and cables are working properly.

If none of the above methods can solve the problem, it is recommended to contact a professional elevator maintenance technician for further diagnosis and <>repair

After the elevator is closed and started, 093 fault is reported.

Hitachi Elevator 093 is usually related to the control system of the elevator. In the case of 093 failure after closing the door and destroying the first start, you can try the following steps:
