The Low Line Scale Factor setting
applications that may utilize more than one type of genset connections. The scale factor setting is
implemented when the DGC-2020 senses a contact closure at a contact input programmed to activate
scaling of the settings. The value of the scale factor setting serves as a multiplier for the threshold
settings. For example, if a scale factor contact input is received bye the DGC-2020 and the scale factor
setting is 2.000, the threshold setting will be doubled (2.000 x PU).
Measurement/Metering Units
The user can configure the DGC-2020 to display and report engine oil pressure and coolant temperature
in English or metric units of measure
Battery Voltage
M
The nominal voltage
of the starter battery is used by the DGC-2020 to detect and annunciate battery
overvoltage and low or weak battery voltage.
NFPA Compliance Level
The DGC-2020 can be used in an application requiring compliance with NFPA Standard 110. Levels 1
and 2 of Standard 110 are supported
ways:
•
The number of crank cycles is fixed at 3
•
Crank cycle time is fixed at 15 seconds
•
Continuous crank time is fixed at 45 seconds
•
The low coolant temperature pre-alarm setting is fixed at 70°F
Horn
An output contact configured (through programmable logic) to energize a horn
disabled through BESTCOMSPlus or at the DGC-2020 front panel.
Single-Phase Override
The DGC-2020 will switch to single-phase voltage sensing
single-phase override input) is received. Either A-to-B or A-to-C sensing can be selected.
Fuel Level Function
Q
This setting
allows the selection of four fuel types: Fuel Lvl, Natural Gas, Liquid Propane, or Disabled.
Selecting a fuel type other than Fuel Lvl will disable any fuel level indication, alarm, and pre-alarm and
disable the Fuel Level value on the Engine screen of the Metering Explorer in BESTCOMSPlus.

Power Up Delay
In some cases, the ECO takes longer than the DGC-2020 to power up. The power up delay setting
used to delay the initial pulsing of the ECU for data on DGC-2020 power up.
