Photocoupler

1. The limit, limit, speed change switch is not the right distance or the switch itself is not good (Note: the slow car is sometimes easy to open and sometimes not easy to open);
2. The upper and lower limit switches are not in contact with one-way crash or occasionally emergency stop;
3. The light load and super full load data are not good (after the flat layer crashes or does not reach the target layer, it will stop after the emergency stop).
4. The performance of the super-full load board is not good (the flat layer is dead after the flat layer);
5. The leveling sensor is not good for the leveling sensor (the car is flat after the crash) (six times self-learning);
6. The encoder performance is not good;
7. The encoder's tail plug is not well soldered, and the contact is not good (occasionally crashes or slams back to leveling the crash, sometimes does not return to the level);
8. The interface between the P1 board and the W1 board is not good enough to crash (turn off the power and turn it on for a while and then crash);
9. There is too much dust on the printing plate, and the weather is wet and the electric crashes (washed with alcohol and dried);
10. The performance of the block itself is not good;
11. The grounding system is not good;
12. The communication part is caused (check whether there is interference, check the communication line, communication board);
13. Flat cable interference (crash after leveling);
14. Power section (check the power supply waveform);
15. The main line is not well contacted (including the lower part of the user);
16. The emergency power supply identification contact is not good (NORR contactor is not connected);
17. The main fuse does not have good contact and there is an emergency stop;
18. The base transformer is not good (after the emergency stop in operation, it will automatically recover or freeze after leveling);
19. There is a slight short circuit inside the base transformer, and the uplink crashes and overvoltage;
20. The performance of the drive module is poor (slowly leveling and then crashing);
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 (stopping after running or leveling after running);
23. The temperature of the inverter is too high (there will be a momentary leveling and then crash, and the blink will recover);
24. The capacity of the main charging capacitor is not enough to crash (sometimes not open);
25. The contact of the grading resistor for the protection of the main charging capacitor is not good (the flat layer is dead or burned).
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 enough to crash;
28. Regeneration resistance is not good (contact is not good or broken);
29. The regenerative resistor is misconfigured and runs in one direction to the upper or lower full load deadlock;
30. The large line of the control panel output to the host is misplaced in the eyes of the transformer (the fast and slow cars are all dead);
31. 5# contactor, LB contactor feedback signal is not good;
32. The wire contact of the brake spark eliminator to the contactor is not good (crash after leveling);
33. The brake contact is not good;
34. The setting of the reporting force is too large or too small to crash;
35. The door part is not good (check the door limit, door encoder);
36. The safety contact plate is not in good contact (gps-3) (cannot start after leveling, but the brake is open and does not return to the level in the middle layer);
37. The control box substrate is not good or the display panel in the car is not good;
38. The safety circuit has resistance (but the light is on, no moving or emergency stop);
39. The door lock circuit has resistance (but the light is on, no moving or emergency stop);
40. The wire rope has slipped more than 16 times (crash after an emergency stop or leveling).
