Configuration
System parameters configure the DGC-2020HD for operation with a specific application. This chapter lists
items to consider when configuring the DGC-2020HD. These items consist of system settings, rated data,
remote module setup, crank settings, automatic restart settings, exercise timer settings, sensing
transformer ratings, relay control settings, and system configuration detection settings.
System Settings
BESTCOMSPlus Navigation Path: Settings Explorer, System Parameters, System Settings
Front Panel Navigation Path: Settings > System Parameters > System Settings
The System Settings parameters consist of number of fly wheel teeth, speed signal source, power-up
delay, fuel level function, NFPA compliance level, EPS supplying load, system units, and metric pressure
units. Figure 166 illustrates the BESTCOMSPlus System Settings screen.
System Type
Select whether the system is a Single Generator or Multiple Generator system.
Number Flywheel Teeth
Number Fly Wheel Teeth is used when calculating engine rpm.
Speed Signal Source
The DGC-2020HD can be configured to detect engine speed from a magnetic pickup (MPU), the genset
frequency, or both MPU and genset frequency. On engines with CAN-compatible ECUs, if MPU or MPU
Freq is selected as the Speed Signal Source, the DGC-2020HD uses the CAN interface as the speed
source when CAN is enabled. If Gen Freq is set as the Speed Signal Source, the DGC-2020HD uses the
generator frequency.
When engine speed is obtained from the genset frequency, the DGC-2020HD uses the rated (nominal)
genset frequency and nominal rpm rating when calculating engine rpm.
When engine speed is obtained from an MPU, the DGC-2020HD uses the number of flywheel teeth when
calculating engine rpm.
The speed signal from the MPU takes priority when both the genset frequency and MPU are selected as
the engine speed source. If both MPU and genset frequency are selected and the MPU fails, the DGC-
2020HD automatically switches to the genset frequency as the engine speed source. Also, a pre-alarm is
issued to indicate the failure of the MPU.
Power-Up Delay
In some cases, the ECU may take longer than the DGC-2020HD to power up. To counteract this, the
power up delay setting can be used to delay the initial pulsing of the ECU for data on DGC-2020HD
power up.
Fuel Level Function
This setting determines whether the fuel level indications and the related alarm and pre-alarm are
enabled or disabled. Setting selections include, Fuel Level, Natural Gas, Liquid Propane, or Disabled.
Selecting a fuel type other than Fuel Level disables any fuel level indication, alarm, or pre-alarm. This
includes the Fuel Level value on the Metering Explorer, Engine screen in BESTCOMSPlus.
Fuel Level Source
If using a resistive fuel level sender, select the Resistive Sender option. In cases where a fuel level
transducer with a 4 to 20 mA or -10 to 10 Vdc signal is used, select the appropriate analog input. Analog
