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.
