Weak Battery Voltage
Weak battery voltage pre-alarm settings consist of an enable/disable setting, a threshold setting, and an
activation time delay. If enabled, a weak battery voltage pre-alarm latches during engine cranking when
the battery voltage decreases below the threshold setting for the duration of the activation delay. The
threshold can be entered in actual volts or a per-unit value. The per-unit threshold value is based on the
nominal battery voltage setting found on the System Parameters, Rated Data screen.
Low Coolant Temp
Low coolant temperature pre-alarm settings consist of an enable/disable setting and a threshold setting. If
enabled, a low coolant temperature pre-alarm occurs when the engine coolant temperature decreases
below the threshold setting. System units are configured on the System Settings screen.
Battery Overvoltage
Battery overvoltage pre-alarm settings consist of an enable/disable setting and a threshold setting. If
enabled, a battery overvoltage pre-alarm occurs when the battery voltage increases above the threshold
setting. The threshold can be entered in actual volts or a per-unit value. The per-unit threshold value is
based on the nominal battery voltage setting found on the System Parameters, Rated Data screen.
ECU Coms Fail
ECU communication failure pre-alarm settings consist of a single enable/disable setting. If enabled, this
pre-alarm is triggered when the DGC-2020ES detects a problem in its J1939 CAN connection to the ECU.
Coolant Level
Low coolant level pre-alarm settings consist of an enable/disable setting and a threshold setting. If
enabled, a low coolant level pre-alarm is triggered when the metered coolant level decreases below the
threshold setting.
Maintenance Interval
Maintenance interval pre-alarm settings consist of an enable/disable setting and a threshold setting. If
enabled, a maintenance interval pre-alarm is annunciated when the DGC-2020ES maintenance timer
counts down to zero from the threshold time setting.
Active DTC
Active DTC (diagnostic trouble code) pre-alarm settings consist of a single enable/disable setting. If
J1939 CAN and DTC support are both enabled, an “active DTC” pre-alarm can be enabled. This pre-
alarm is triggered when a DTC is sent from the ECU to the DGC-2020ES.
Low Oil Pressure
Low oil pressure pre-alarm settings consist of an enable/disable setting and a threshold setting. If
enabled, a low oil pressure pre-alarm is triggered after a two second delay when the engine oil pressure
decreases below the threshold setting. The arming delay disables the low oil pressure pre-alarm function
for a user-adjustable time during engine startup. Delay duration is determined by the Low Oil Pressure
Alarm Arming Delay setting. System units and metric pressure units are configured on the System
Settings screen.
CEM Comm Failure
CEM-2020 communication failure pre-alarm settings consist of a single enable/disable setting. If enabled,
this pre-alarm is triggered when communication between the optional CEM-2020 and DGC-2020ES is
lost.
Checksum Failure
When one of the internal checksum calculations, used for data integrity purposes, has failed, the
checksum failure pre-alarm is triggered. This indicates that some of the user settings or firmware code
has been corrupted.
