I have a Varion 979 now Agilent.  I have the pumps DS 302 and SD-451 attached.


When I turn on the unit the roughing pump usually starts as the unit warms up.  Today the roughing pump did not start screen just says "Roughing System Pressure Wait".  Tried to engage the system to measure a leak rate to engage the Turbo Pump; still nothing.  All seems dead down below.


Shut down the unit and turned back on, still nothing.  Pushed the fuse resets, redid the power cords, check switches on pumps and still dead pumps.  What gives?
