How to deal with the failure of the Mnak E56

1. Check the output side of the inverter and run the contactor.

Whether it is normal or not. 2. Check whether the power line has surface damage, whether there is the possibility of short circuit to the ground, and whether the connection is reliable.

3. Check whether there is a copper wire at the terminal end of the motor side.

4. Check whether the inside of the motor is short-circuited or grounded.

5. Check whether the star sealing contactor causes a short circuit in the output of the inverter.

6. Check whether the motor parameters are with the nameplate.

Match. 7. Re-carry out the self-learning of motor parameters.

8. Check whether the brake continues to open before reporting the fault.

9. Check whether there is any mechanical stuck.

10. Check whether the balance coefficient is correct, etc.

1. The fault of E56 of Menak elevator refers to: abnormal double reference voltage.

2. Solution:

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

If none of the above behaviors can solve the problem of abnormal reference voltage, the only way to replace the ACR board or MPU board is to use a new electronic board.

4. Cause of failure:

An abnormality occurs in the mechanical parts of the elevator or the components in the electrical control system.

Detailed solution to the fault of Monak E58 Hello dear, the fault of the elevator E58 is the abnormal fault of the position protection switch. Cause of failure : 1

The upper and lower strong wave deceleration switches are effective at the same time; 2.The upper and lower limit switches are effective. The solution is as follows:

1.Check whether the parameters of the forced deceleration switch and limit switch (normally open, normally closed) are consistent with the parameters of the main control board of Zao Ranyou; 2.Check if the forced deceleration switch is faulty.

3.Please ask elevator maintenance professionals to come to the door for maintenance. I hope I can help you!

If my answer is helpful to you, please also give a thumbs up (in the lower left corner of the evaluation), look forward to your like, your efforts are very important to me, your support is also the motivation for me to improve the stool pin, and finally I wish you good health and a happy mood!

1.Check the output side of the inverter and see if the contactor is running normally. 2.

Check whether the power line is damaged on the surface, whether there is the possibility of short circuit to the ground, and whether the connection is reliable. 3.Check whether there is a copper wire on the ground at the terminal on the motor side.

4.Check whether the inside of the motor is short-circuited or grounded. 5.

Check whether the star sealing contactor causes a short circuit in the output of the inverter. 6.Check whether the motor parameters are consistent with the nameplate.

7.Re-take the motor parameters for self-learning. 8.

Check whether the brake is continuously open before the potato rots and loses. 9.Check for mechanical jamming.

1. Caused by short circuit of power plug, power lead wire and motor winding.

Solution: Repair the power plug and motor winding.

2. The starting capacitor or starting winding is damaged.

Solution: The capacitor of the same capacity should be replaced or the starting winding should be repaired; If the motor is stuck, 3. It is a mechanical fault of the motor and pump head, such as bearing damage, impeller jamming, etc.

Solution: Repair the motor and pump head.

Hello, E62 (repair fault) overhaul status; Check the gap between the brakes and confirm that the brakes are working properly; Re-do the braking force test to see if there is a change in the F4-03 pulse, if there is a change, it means that the braking force of the brake is not enough, and you need to contact the regret manufacturer. After passing the braking force test, it will automatically reset the E66 fault. Braking force detection steps:

1. The maintenance switch is effective, the elevator stops at the position of the door area, and the door is kept closed 2, the keypad is set to F-8 and 8, the braking force test function is turned on, the keypad shows the trembling regret E883, after the door lock is effective, the star is sealed, the contactor is output, and the brake contactor is not output 4, the system output torque is gradually increased to 110% of the rated torque, and the test results are continuously increased to 5S5, F7-09 shows the test results, 1: qualified, 2: unqualified immediately reported E66, and the fault cannot be reset; Fault Reset:

It is necessary to redo the brake force test, and the result is 1 before resetting.

Directly connect an outbound call board to the corresponding terminal on the inverter motherboard to see if it is a problem with the motherboard or a problem with the wiring. Look at what brand of inverter or motherboard model, find the corresponding fault**, if it is a Menak inverter system, E52 can refer to the following: E51 CAN communication failure:

Reasons: 1. There is no correct feedback data in CAN communication. 2. CAN communication reception continues to error.

Countermeasures: 1. Check the communication cable connection. 2. Check the power supply of the control panel on the roof of the car.

3. Check whether the 24V power supply of the elevator integrated controller is normal. E52 Outbound Communication Failure: Outbound Communication has no normal feedback data.

1. Check the communication cable connection. 2. Check whether the 24V power supply of the elevator integrated controller is normal. 3. Check whether the address setting of the external call control board is repeated.

E53 Door lock short-circuit fault: under the automatic operation of the elevator, there is no door lock disconnection process when parking 1. Check whether the door lock circuit action is normal. 2. Check whether the feedback electric shock action of the door lock contactor is normal.

3. Check that the system has received the signal of opening the door in place when the door lock signal is effective. Supplementary description of fault recording: 1. E41 does not record this fault in the elevator stop state.

2. E42 This fault is the automatic reset when the door lock is turned on and the automatic reset after the failure of the door area for 1s. 3. When there is an E51 or E52 fault, if the fault continues to be valid, it will only be recorded once every 1 hour.

The failure of the E50 system in the Murnac system is half due to hardware or software problems in the operating system. Possible causes include:1

Hardware failure: Due to the aging or damage of hardware equipment, it may cause system failure. 2.

Software failure: Due to a bug or software error in the system software, the system may malfunction. 3.

Network failure: Due to network reasons, the system may fail. 4.

System misconfiguration: Due to system misconfiguration, the system may fail. 5.

Power failure: Due to a power failure, the system may fail. In case of a Menak system E50 failure, it is recommended to check the above possible causes and try to reinstall the operating system in order to fix the problem.
