Hi managers,
I hope, someone is still watching the list. This is more a hardware question.
I have a GS140 (converted from a 8400). The fan caused a machine stop. Since the
fan wasn't working anymore. I checked the power supply to the fan. Everything
was normal, no power supply was broken. Therefore I pulled the fan housing. In
the housing is a controlling unit installed. The controlling unit has a 6.3 A
fuse that protects the input. The fuse was broken. After replacing the fuse, the
fan started working again (I provided 48V by a external power supply).
Since everything seems to be in workng condition again, I'm curious, why the
fuse broke. Is anybody out there who has gotten across the same problem? May be
the fuse is a bit to close to the maximum current that is needed by the fan.
I've seen a peak of 7 A during start of the fan. Would it help to replace the
fuse by a 8A type?
Thank you very much.
