This winter vacation is longer, the children stay in the side of the time is very much, every day is mother today at noon what to eat? What does Mom eat at night? I had to work much less. I had an ABB soft-start board repaired a few years ago. I rarely encountered communication problems several times a year. A chemical plant in Deyang, Chengdu.

 

The tests are as follows:

Brand: ABB

Model: ABB PSTX570-600-70

Power: 320KW

Voltage: 380-660V

Current: 570A

Fault: The alarm will be triggered upon power-on, and the fault will display Check Connection. What do you mean? The main control board is not communicating with the operation panel. After replacing the mainboard onsite, the power-on display is normal and the startup is normal. ABB soft start, no limitation of model, no limitation of fault, no replacement of plate maintenance, can be contacted.

Maintenance idea: The soft-start communication faults mainly occur in Eaton S81+, S801 and ABB PSTX series motherboards. They are all very classic faults, and it is really not easy to fix them. All rely on the more than ten years of theoretical knowledge and maintenance experience, engage in circuit board maintenance too much, want to rise a stage, theory is the biggest cornerstone, coupled with a wealth of fault maintenance cases, want to grow is difficult. Backwards schematics from failures, nothing bad. It's all about time.

After repeated testing and comparison, this set of control board almost 2 days to confirm the cause of the failure, after lifting the power normal, normal startup. The factory started normally, no trip or alarm has been seen so far, and the fault has been repaired.
