So finished off the last few items on my list over the last few weeks and got all the final wiring done yesterday. I turned it on yesterday and everything seemed ok, so since everything seemed to be in working order i thought it would be a good idea to do a water trial today. Before doing the trial i had to update the web interface on the panel PC (it has an old version of IE on it). While in the process of doing this, i heard a pop in the panel and everything except the blue main power light died. first reaction, OH SH!T !!!!! after disconnecting the power i opened it up and started looking around, i was hoping it was one of the quick blow fuses for either the BCS or the panel. So i changed the fuse, connected the power and tried to turn it on again. The blue Main power light turned on but nothing else happened. So now I'm thinking to myself, ok time to see where there is and isnt power flowing. So with a pen style voltmeter i quickly started testing wires and low and behold it looks like i somehow blew the coil on the first contactor (the one which lets power into the enclosure and goes to everything else). So that was a HUGE relief. Now the question remains how did i blow the contactor coil???? Thoughts? I had a similar setup on my old system and never blew the coil, maybe it was just a faulty contactor, cuz if i'm not mistaken the coil should last for something like a million throws. If anyone has any other ideas please advise.
