Have three chauvet legend 5000 lighting fixtures that keeps blowing fuses and giving error dmx adresses on display.... can some one help?

Are you sure you are using the correct type of fuses ?
I E - using fast blow instead of slow blow ?
Faulty lamps, igniters and capacitors is next in line !
Faulty ballast is next to check !

First of all, welcome to CMN.

Since you have three units that do the same thing - did you buy them this way or have you owned them for a while and this has started to happen?

If you have owned them for a while - and then the units have started blowing fuses - is there something that you (or someone else) has done that could have possibly caused this?

As these are moving head fixtures with HMI575 lamps there are a whole raft of things that can cause the fuses to blow (some of which have been dealt with in the previous post).

Which fuse is blowing? According to the manual I downloaded there are two fuses. The external fuse is the mains fuse (20mm 15A fast blow 250V - but then I am in the UK so this may differ if you are in a 110V region). The internal fuse is a 20mm 5A fast blow 250V.

As both fuses appear to be fast blow - the issue regarding fast blow / slow blow should not be causing a problem - although don't swap a fast blow fuse with a slow blow fuse to see if that cures the problem! It may do - but this is not as designed and could cause more damage (or a serious fire) down the line!!!
