    keyword=tech/Quench reset

    Called in for fault on right dipole and Q3 after quench. Q3 cleared after diddling with the lever. It seems to be out of adjustment and would not latch. Dipole would fault on the GUI but no fault indicated on the power supply or interlock rack. I cycled power on the Allen Bradley and waited….. and reset the interlock rack. The controls became operational but the ramp was slower than normal. I stopped the ramp and de-powered everything and waited….. On start up the controls responded as they did on the original fault. De powered the power supply with the switch on the power supply and waited……. Re powered and reset the interlock rack. This time I got a clunk in the power supply and the controls responded correctly
