Cause of failure of Mitsubishi Lingyun No.2 elevator 53A537

Cause of 53A537 failure of Mitsubishi Lingyun 2 elevator: the plug at the end of the encoder is not welded well and the contact is not good; General performance: occasionally hitting the plane or stopping to return to the flat floor, sometimes not returning to the flat floor;

Causes of common faults of Mitsubishi elevator:

1, limit, clearance, improper distance of variable speed switch or bad switch itself (note: sometimes the local train is easy to drive and sometimes it is not easy to drive);

2. Poor contact between the upper and lower limit switches leads to one-way collision or occasional emergency stop;

3, light load, overload data is not good (crash after leveling or crash after the destination layer stops);

4. The overload plate has poor performance (crash after leveling);

5. The leveling sensor is not working well again (the express train crashes after leveling) (self-study for half a year);

6, the encoder performance is not good;

7. The plug at the end of the encoder is not welded well and the contact is not good (occasionally it crashes or stops and goes back to the flat layer, sometimes it doesn't);

8. The interface between P1board and W 1 board is in poor contact and crashes (power off and power on for a while and then crashes);

9. There is too much dust in the printing plate, and the sensor crashes when the weather is wet (alcohol is washed to dry);

10, the performance of the program block itself is not good;

Extended data:

At present, there are not many manufacturers who can do Mitsubishi elevator intelligent control in the domestic market, because most domestic manufacturers of elevator intelligent ic control use relay principle to control elevators through on-off technology. This technology is universal and can control more than 90% of elevators in the domestic market, but it cannot control all models of Mitsubishi elevators.

In China, the key control of Mitsubishi elevators adopts row-column matrix scanning technology, and more than 50% of Mitsubishi elevators adopt bus control, so it is impossible to distinguish the key lines. Therefore, the relay can only realize a few Mitsubishi elevators, and the installation is quite troublesome, so the development engineer must go to the scene to guide.

At present, only a few manufacturers in China, such as Yiheng Elevator Intelligent, adopt bus protocol elevator intelligent IC controller to communicate with Mitsubishi elevator through CPU scheduling, so as to perfectly control all types of Mitsubishi elevators, and develop all intelligent applications on this basis, with zero damage to elevators.
