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.

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.

Inputs are provided for oil pressure, fuel level, and coolant temperature senders.
Oil pressure senders that are compatible with the DGC-2020 include Datacon 02505-00, Isspro model
R8919, and Stewart-Warner models 279BF, 279C, 411K, and 411M. Other senders may be used.
Compatible fuel level senders include Isspro model R8925. Other senders may be used.
Coolant temperature senders that are compatible with the DGC-2020 include Datacon 02019-00, Faria
TS4042, Isspro model R8959 and Stewart-Warner model 334-P. Other senders may be used.
Sender input terminals are listed in Table 6-5.
NOTE
Unused current sensing inputs should be shorted to minimize noise pickup.
