Hi,

I'm working on a Varian 921-0062 ion pump controller for the pumps used
in a Maser.

I just got it in and it is wired for 240 VAC and I want 120VAC.
 
My manual and the ones I can find on line show a power TX with 4 input
terminals which they show how to strap for 240 or 120 VAC.
 
My unit has TX has 6 terminals 1/2/3/4/8/9.
 
Does anyone know how to wire this TX for 120 VAC?
 
Thanks,
 
Corby Dawson
