CHAPTER 5:TROUBLESHOOTING
5.3 Fail to start - Continue
Check points:
1) EMC board issue.
2) Transformer issue.
3) Software issue.
4) Controller issue.
Solution:
1) Confirm if the power supply and EMC filter board are normal. Measure if AC110V
(AC220V in mainland China) power supply of output end of EMC board is normal.
Possible cause: EMC board fuse damage, EMC board damage or poor contact of connecting
line.
The main purpose is to measure if the input end voltage has output voltage (AC110V or
AC220V) after passing through the filter; if there is no voltage, check if the fuse is burned (The
power must be off when measuring the fuse).
When the fuse is not burned, and there is still no output voltage, replace the filter.
1.Turn on the power supply.
2.Remove screws and cover.
Put the probe on
the power supply
input end.
Switch to AC on
the power on the
power supply to
conform voltage.
Test if the output
end voltage
conforms to the
input end.
Turn off the
power,measure
if the fuse is
damaged.
