Well, I was going to ask about strange behavior in one of my ArIons, but looks like this overtook it.
Posting here, to see if LSRFAQ or anyone else may have any ideas what I may be able to do to troubleshoot this.
About an hour ago, my JDSU 2110U-SLCPEB power supply was chugging along fine, running my lasers on their monthly run-in. Brought some of them up to 10A (this supply was the only one of my many that would do over 8a out), no problems.
Was doing the run on one of my multilines, got called in for dinner. Set the power to idle for a few minutes, then turned the tube current off, turned the interlock off, and unplugged the power supply.
Came back an hour later, and now, while the red interlock light is bright red , the green interlock LED is dim; the fan turns slowly, the JDSU interface is lit up dimly and the numeric display on the interface reads "7.89" even if tube current is set to off.
Needless to say it won't start any lasers anymore.
The interface is fine, as it works with all of my other JDSU 2110 supplies (the 'gold box' ones); lights up brighter and no problems at all.
There's no 220/110 switch on this; it uses the 20a cord style, [-_-] and for my ham radio stuff out here, I *do* have 20a service and 20a outlets. So current draw shouldn't be the problem.
Just not sure why it was running happily an hour ago, and sometime between unplug and plug-back-in, now its all dim/slow fan/no start. Since nobody on earth seems to have another one of these (except on ebay, from sellers that are charging $1500 for EOL tubes as well) - I was wondering if anyone had any idea where to even start to troubleshoot this and hopefully repair it. I spoke to Dave, who I got it from originally, and he says it's beyond his expertise. (and, he doesn't have any more...)
Any info at all would be greatly appreciated...
