Figure 4-14. System Settings Screen
Rated Engine RPM. This setting selects the rated rotating speed of the engine. A value of 750 to 3,600 rpm
may be entered.
Maintenance Interval Timer Reset. Selecting this checkbox terminates the maintenance interval pre-alarm
and resets the maintenance interval timer back to the programmed value. The Send Settings button must be
clicked for the reset to take effect.
Battery Volts. This setting selects either 12 Vdc or 24 Vdc as the starting battery nominal voltage.
NFPA Level. This setting selects whether or not NFPA requirements are in effect. If NFPA (National Fire
Prevention Association) compliance is not required, a setting of zero (0) can be selected to disable the feature.
Selecting NFPA level one (1) or two (2) affects DGC-500 operation in the following ways.
C
The number of crank cycles is fixed at 3.
C Crank cycle time is fixed at 15 seconds.
C
Continuous crank time is fixed at 45 seconds.
C
The low coolant temperature pre-alarm setting is fixed at 70°F.
# Flywheel Teeth. This setting selects the number of teeth on the engine flywheel. A value of 50 to 500 may
be entered.
Speed Signal Source. This setting selects from three sources for obtaining the engine speed. The speed
signal source can be obtained from the magnetic pickup (MPU), generator frequency, or derived from both
the MPU and generator frequency. When both the MPU and generator frequency are selected as the speed
signal source, the MPU has priority. If both MPU and generator frequency are selected and the MPU fails,
generator frequency is used and a non-programmable MPU sender failure pre-alarm is annunciated.
Embedded Firmware Version. This read-only field displays the firmware version of the DGC-500.
Generator Connection. This setting selects the configuration of the generator voltage sensing circuitry. Either
three-phase line-to-line, three-phase line-to-neutral, or single-phase A-phase to B-phase sensing may be
selected.
Generator Frequency. This setting selects either 50 hertz or 60 hertz as the nominal generator frequency.
Unit System. This setting selects either the English or Metric unit system for displaying the oil pressure and
coolant temperature parameters in BESTCOMS, the DGC-500 HMI, and the optional Remote Annunciation
Display Panel (RDP-110).
