The Pump Station had only just recovered from shutdown Sunday July 13 and again shutdown on 17 July where it has remained.  The attached 20 day plot of Cartesian basis position Dofs shows the shutdown clearly after a few days of flat position loop control, the step to Pump off position for a couple days, a step to Pump on but HEPI not Isolated for a couple days and then another step back to Pump off period for the remainder.  The amount of shifting from Pump off to on is in the 10s of micro range.

The shutdown was due to the familiar OV3, overvoltage at constant speed.  EE tells me we could possibly put some inductor on the line to reduce this.

Anyway, no problem getting this back on, usual process.
