Mitsubishi elevator Erro code
From GPS, GPS2 to GPS3, the system mechanism of Mitsubishi Elevator has undergone great changes, and the operation method has been quite different. But its basic failure code is the same. In actual repairs, the fault code is just a reference for repairs:

Motherboard Fault Code:
E0 is fault-free
E1 underspeed fault
E2 overspeed fault
E3 reverses the failure
E4AST fault (stall)
E5 overcurrent
E6 overvoltage
E7 undervoltage
E8LB contactor failure
E9 contactor fault
EA BK gate fault
EB car serial transmission fault
EC hall layer serial transmission fault
ED System Error (Baseboard Jumper Setting Error)
The EEsddnrs driver computer can no longer boot
The EFswnrs2 control computer can no longer boot

Door panel fault code:
0 Serial transfer error
1 Inverter overcurrent
2 +12v undervoltage
3 Main loop undervoltage
4 CPU WDT error
4. GS (Door Lock) error
5. Position switch error
7 Wrong opening and closing door instructions
9 Closing operation error
A switch door overspeed
A. Error with the position counter
B. Error in position monitor
C. Encoder error
D Overload
E. Insufficient DLD margin
F Overspeed inspection
F. Indicated when GS is released

Mitsubishi elevator crash causes:
1. The distance of the limit switch, the speed shift switch is improper or the switch itself is not good;
2. The upper and lower limit switches are not in contact with one-way crashes or occasional emergency stops;
3. Light load, overload data is not good (crash after the flat layer or crash after emergency docking of the flat layer without reaching the destination layer);
4. Poor performance of the overloaded board (crash after flat layer);
5. The flat layer sensor is not good (crash after the express flat layer) (do self-study in half a year);
6. The encoder performance is not good;
7. The encoder tail plug is not welded well, the contact is not good (occasionally crash or emergency stop to return to the flat layer, sometimes not back to the flat layer);
8. The interface between the P1 board and the W1 board is not in good contact with the dead machine (then turn off the power transmission for a period of time and crash again);
9. There is too much dust on the printing board, and the weather is wet and the induction electrocution machine (wash it with alcohol and blow dry it);
10. The performance of the program block itself is not good;
11. The grounding system is not good;
12. Caused by the communication part (check whether there is interference, check the communication line, communication board);
13. Flat cable interference (crash after flat layer);
14. Power supply part (check the power supply waveform);
15. The contact of each main line is not good (including the lower part of the user);
16. The contact contact of emergency power identification is not good (the NORR contactor is not accretive);
17. The main fuse is not in contact with the emergency stop phenomenon;
18. The base transformer is not good (automatic recovery after an emergency stop during operation or crash after leveling);
19. There is a slight short circuit inside the base transformer, an upward crash, and an overvoltage;
20. Poor performance of the drive module (crash after slowly leveling the layer);
21. The drive board or its plug is not good;
22. The driver block on the driver board itself is not good or the program is not good (emergency stop during operation or crash after leveling);
23. The inverter temperature is too high (there will be a crash after the instantaneous flat layer, and it will recover in the blink of an eye);
24. The main charging capacitor capacity is not enough to crash (sometimes it cannot be turned on);
25. The contact with the voltage equalization resistance protected by the main charging capacitor in an instant is not good (crash or burn the charging capacitor after the flat layer);
26. The transformer plug or itself is not good (fast and slow cars are not easy to open);
27. The performance of the regeneration module is not good and the machine crashes;
28. The regenerative resistance is not good (poor contact or broken wire);
29. The regenerative resistor is misconfigured, running in a certain direction to the upper or lower part fully loaded panic;
30. The large line of the control screen output to the host is worn incorrectly in the eyes of the transformer (both fast and slow cars crash);
31. 5# contactor, LB contactor feedback signal is not good;
32. The line contact from the brake spark eliminator to the contactor is not good (crash after the flat layer);
33. The contact point of the gate is not good;
34. The setting of the gate reporting force is too large or too small to crash;
35. The door machine part is not good (check the switch threshold, door machine encoder);
36. The safety contact plate is not good (GPS-3) (it cannot be activated after the flat layer, but the holding gate is open, and the middle layer is not returned to the flat layer);
37. The control box substrate is not good or the display board in the car is not good;
38. The safety circuit has resistance (but the lights are on, the car is not moving or the emergency stops);
39. The door lock circuit has resistance (but the lights are on, the car is not moving or the emergency stops);
40. Wire rope slipped more than 16 times (crash after emergency stop or flattening).
