Tianjin customer sent a
Rockwell soft start, start the alarm, want to repair
spare.
Check as follows
Brand: AB Rockwell
Model number: 150-F108NBD
Current: 108A
Power: 55KW
Fault: The power supply display is normal, and the alarm
is immediately triggered. The fault number is 7 pole open
R.
Maintenance idea: The thyristor gate opening is
one of the AB Rockwell soft start is not good to judge the fault,
before encountered the situation of sending repair, controller head
bad situation, occasionally host and controller are bad, almost all
are industrial control master admire dinner, after all, AB Rockwell
soft start our maintenance experience is the most rich.
This soft start, the initial judgment is the controller
fault, fortunately is started on the report, the fault point is
good to confirm some, before there should be a failure many times,
after each restart can run for a period of time, until completely
can not work. In the operation of the alarm open
circuit fault, especially the alarm is not timed, this is more
difficult, simulation is the key, then according to the schematic
diagram to repair the controller.
After the controller is repaired, the host test runs for
more than ten seconds and the alarm is not loaded, which still
takes most of the day until it starts normally. After the
reliability test, it has been sent to Tianjin. The
fault is rectified.
