9400200990 Rev B DGC-2020 BESTCOMSPlus Software 4-15
Horn
An output contact configured (through programmable logic) to energize a horn
M
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
N
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
O
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.
BESTCOMSPlus system settings (DGC-2020, System Parameters, System Settings) are illustrated in
Figure 4-15.
Figure 4-15. BESTCOMSPlus System Settings

Crank Settings
The DGC-2020 can be programmed for either cycle or continuous engine cranking A . Cycle cranking
provides multiple engine starting attempts
B
. Each starting attempt consists of a fixed interval of engine
cranking
C
followed by a rest interval of the same duration. Continuous cranking
D
provides a single,
extended engine-starting attempt.
The DGC-2020 uses the engine speed signal (supplied by a magnetic pickup (MPU) or the generator
frequency) and the Crank Disconnect Limit setting
E
to detect engine startup (and determine when engine
cranking can be stopped). The Crank Disconnect Limit setting is expressed as a percentage of the
nominal engine speed.
