FUNCTIONS
DGC-2020 Digital Genset Controllers perform the following
functions:
Generator Protection and Metering
Generator protection guards against over voltage, under voltage,
under frequency, and over frequency. Over current and phase
imbalance protection is available as an option at the time of
manufacture. Each generator protection function has an adjust-
able pickup and time delay setting. Metered generator param-
eters include voltage, current, real power (watts), apparent power
(VA), and power factor (PF).
Engine Protection and Metering
Engine protection features include oil pressure and coolant
temperature monitoring, over crank protection, ECU specific
protection elements, and diagnostic reporting.
Metered engine parameters include, oil pressure, coolant
A - Liquid Crystal Display. The backlit, 64 by 128 pixel LCD
serves as the local information source for metering, alarms, pre-
alarms, and protective functions. Display operation is maintained
at -20°C. An optional LCD heater maintains display operation at -

2020 is not operating in Auto mode.
C - Alarm Indicator. This red LED lights continuously during
alarm conditions and flashes during pre-alarm conditions.
D - Supplying Load Indicator. This green LED lights when the
generator current is greater than EPS threshold current.
E - Alarm Silence Push-button. Pressing this button opens the
relay output programmed as the horn output.
F - Lamp Test Push-button. Pressing this button tests the DGC-
2020 indicators by exercising all LCD pixels and lighting all LEDs.
