I am working on a Daewoo Puma 12L-B with a Fanuc Series O-T control.
I was called in because they couldn't get it to power up. Everything kept pointing to the Power Supply Module (A06B-6087-H130). I opened it up and found that the internal fuse, F1, was blown. The book I have lists it as a 7.5 amp fuse. I pulled out a 5 amp fuse. I believe the type of fuse is a Daito HM series. Not positive.
My questions are:
What caused this fuse to blow?
What is the correct amperage for this fuse?
Thanks,
Heath.
