4-18 DGC-2020 BESTCOMSPlus Software 9400200990 Rev I
The Low Line Scale Factor setting
K
is used to automatically adjust the EPS threshold settings in
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
L
.
Battery Voltage
The nominal voltage
M
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
N
. Selecting level 1 or 2 affects DGC-2020 operation in the following
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
O
can be enabled and
disabled through BESTCOMSPlus or at the DGC-2020 front panel.
Single-Phase Override
The DGC-2020 will switch to single-phase voltage sensing
P
when a contact input (programmed as a
single-phase override input) is received. Either A-to-B or A-to-C sensing can be selected.
Fuel Level Function
This setting
Q
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.
Load Sharing Module
A J1939 Address
R
must be entered when an optional LSM-2020 is enabled
S
.
Power Up Delay
In some cases, the ECO takes longer than the DGC-2020 to power up. The power up delay setting
T
is
used to delay the initial pulsing of the ECU for data on DGC-2020 power up.
Contact Expansion Module
A J1939 Address
U
must be entered when the optional CEM-2020 is enabled
V
.
BESTCOMSPlus system settings (DGC-2020, System Parameters, System Settings) are illustrated in
Figure 4-16.
