Generator Voltage Sensing
The DGC-2020 accepts either line-to-line or line-to-neutral generator sensing voltage over the range of 12
to 576 volts, rms line-to-line. Depending on the style number, a DGC-2020 will have a nominal generator
frequency rating of 50/60 hertz or 400 hertz. A style number of x1xxxxxxxx indicates 50/60 hertz
generator voltage and a style number of x2xxxxxxxx indicates 400-hertz generator voltage. Generator
voltage sensing terminals are listed in Table 6-3.

Terminal Description
35 (GEN VN) Neutral generator voltage sensing input
37 (GEN VC) C-phase generator voltage sensing input
39 (GEN VB) B-phase generator voltage sensing input
41 (GEN VA) A-phase generator voltage sensing input
Bus Voltage Sensing
Sensing of bus voltage enables the DGC-2020 to detect failures of the mains (utility). Controllers with
style number xxxxxxxAx use bus voltage sensing to perform automatic synchronization of the generator
with the bus (style number xxxxxxxAx only). The DGC-2020 senses A-phase and B-phase bus voltage.
Bus voltage sensing terminals are listed in Table 6-4.
