Main power is connected to terminals L1, L2, and L3 on the Delta drive. If the washer is connected to a Pressure Switch Caution (Not recommended by Factory!) three phase source, there should be voltage present on all three terminals.
Electrical Path Circuit Schematics Start Circuit Power travels into the machine on L1 & L2 & (L3, if 3 phase used). L1 and L2 provide 208- 240VAC to the controls transformer which steps the voltage down to 120VAC for the controls. (The L1 connec- tion at the controls transformer must be checked at start-up to coincide with machine operating voltage) The 120VAC travels out from the transformer on either [X-1 red wire directly to the 1.5 amp fuse] or [X-1...
