inputs 1 and 2 can always be selected. Analog inputs 3 and 4 are available to DGC-2020HD units with the
analog sender inputs option (style number xxxxxxxxA).
Coolant Temperature Source
If using a resistive coolant temperature sender, select the Resistive Sender option. This option is only
available to DGC-2020HD units with resistive sender inputs (style number xxxxxxxxR). If using a coolant
temperature transducer with a 4 to 20 mA or -10 to 10 Vdc signal, select the appropriate analog input.
Analog inputs 1 and 2 can always be selected. Analog inputs 3 and 4 are available to DGC-2020HD units
with the analog sender inputs option (style number xxxxxxxxA).
Oil Pressure Source
If using a resistive oil pressure sender, select the Resistive Sender option. This option is only available to
DGC-2020HD units with resistive sender inputs (style number xxxxxxxxR). If using an oil pressure
transducer with a 4 to 20 mA or -10 to 10 Vdc signal, select the appropriate analog input. Analog inputs 1
and 2 can always be selected. Analog inputs 3 and 4 are available to DGC-2020HD units with the analog
sender inputs option (style number xxxxxxxxA).
NFPA Compliance Level
The DGC-2020HD can be used in an application requiring compliance with NFPA Standard 110. Levels 1
and 2 of Standard 110 are supported. Selecting level 1 or 2 affects DGC-2020HD operation in the
following ways:
•
Number of crank cycles is fixed at 3
•
Crank cycle time is fixed at 15 seconds
•
Continuous crank time is fixed at 45 seconds
•
Low coolant temperature pre-alarm setting is fixed at 70°F
•
Off Mode Cool Down is disabled
•
Not In Auto Horn Enable setting is Enabled
•
Horn setting is Enabled
EPS Supplying Load
EPS Supplying Load options are Low-line Scale Factor and EPS Threshold. These settings are described
in the following paragraphs.
Low-line Scale Factor
Low-line Scale Factor automatically adjusts the EPS threshold setting in applications utilizing more than
one type of genset connection. The scale factor setting is implemented when the DGC-2020HD is
determined to be in a low-line configuration. If the Low-Line Override function is assigned to a contact
input via the Programmable Functions screen, the state of the contact input and the detected
configuration are ORed. This means, if one or both are true, then the system is determined to be
configured for low-line. The value of the scale factor setting serves as a multiplier for the threshold setting.
For example, if a scale factor contact input is received by the DGC-2020HD and the scale factor setting is
2.000, the threshold setting is doubled (2.000 x Threshold setting).
EPS Threshold
Indication that the emergency power system is supplying load is determined by a user-adjustable
threshold setting. This setting is expressed as a percentage of the genset CT (nominal) primary rating.
This setting accepts values from 3 to 10, in increments of 1%.
System Units
Engine oil pressure and coolant temperature can be displayed in English or Metric units of measure.
