Eventually we were forced to upgrade to the new model. At the time QD offered us a discount and we were able to do it for ~$6500. When the problem was intermittent, on the advice of QD we increased the heating time of the switch from 20-30 seconds (can do in the Model 6000 panel).

I'm not familiar with this particular equipment, but I've experienced a similar problem due to a bad hall sensor on a large magnetic dipole. In my setup the ps adjusts itself according to the feedback it gets from a hall sensor, and if it is not well-positioned I cannot control the ps. Anyway, the problem is likely a sensor, relay or control cable which should all be easy to test. I've also had problems with Kepco ps shorting at high power.jimnoreply@blogger.comtag:blogger.com,1999:blog-13869903.post-46526958927476083732016-04-29T23:04:15.935-05:002016-04-29T23:04:15.935-05:00I Dont have any answerI Dont have any answerHura Hoashttp://carapemanasanglobal.blogspot.com/noreply@blogger.com
