Hello all,

I'm looking for assistance with a problem after a power outage: the 
pumps on our Delta Plus XL will not turn back on.

When I toggle the source pump button, nothing happens (LED light does 
not come on, no pump activity). The instrument does indeed have power 
(various fans and electronics are humming), and I have reset the 
breakers on the back.

The roughing pump itself is fine - it works fine when plugged into a 
hot socket. I've also gone through the system looking for blown fuses 
and loose cables. I've also left it unplugged for a few hours hoping 
for a miraculous reset of some sort. No luck.

Any ideas?
