A weak battery pre-alarm condition is reset through the front panel by navigating to the Alarms-Status,
Pre-Alarms screen, scrolling through the list of pre-alarms until “Weak Battery” is displayed, and pressing
the Reset key.
Battery Overvoltage
Battery overvoltage pre-alarm settings
consist of an enable/disable setting and a fixed threshold setting.
If enabled, a battery overvoltage pre-alarm occurs when the battery voltage increases above 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-2020 maintenance timer counts
down to zero from the threshold time setting.
Engine KW Overload
By comparing the genset power output with the rated genset output, the level of engine loading can be
determined. Engine overload pre-alarm settings
consist of an enable/disable setting and a threshold
setting. If enabled, an engine overload pre-alarm occurs when the metered power level exceeds the
threshold setting. The threshold setting is expressed as a percentage of the genset kW rating on the
BESTCOMSPlus System Settings tab (DGC-2020, System Parameters, System Settings).
Low Fuel Level
Low fuel level pre-alarm settings
consist of an enable/disable setting and a threshold setting. If enabled,
a low fuel level pre-alarm occurs when the metered fuel level decreases below the threshold setting.
High Coolant Temp
High coolant temperature pre-alarm settings
consist of an enable/disable setting and a threshold setting.
If enabled, a high coolant temperature pre-alarm is annunciated when the engine coolant temperature
exceeds the threshold setting for a fixed duration of 60 seconds.
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.
Low 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 occurs when the metered coolant level decreases below the
threshold setting.
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 annunciated when the engine oil pressure decreases below the
threshold setting for a fixed duration of 10 seconds.
ECU Com’s Fail
ECU communication failure pre-alarm settings
consist of a single enable/disable setting. If enabled, an
ECU communication failure pre-alarm is annunciated when the DGC-2020 detects a communication
problem in the J1939 interface linking the DGC-2020 with the ECU (engine control unit).
Active DTC
Active DTC (diagnostic trouble code) pre-alarm settings
consist of a single enable/disable setting. If
CAN and DTC support are both enabled, an “active DTC” pre-alarm may be enabled to announce the
presence of a condition that is causing a DTC to be sent from the ECU to the DGC-2020.
