Reporting and Alarms
The DGC-2020ES monitors ECU data, generator protection functions, and engine senders. An alarm or
pre-alarm is annunciated when the monitored parameter exceeds its threshold settings.
When an alarm condition exists, the engine is stopped by opening the Fuel output contact. An existing
pre-alarm condition is annunciated only.
When alarms are active, the front panel Overview screen is replaced by the Active Alarms screen. When
only pre-alarms are active, the front panel Overview screen is alternated with the Active Pre-Alarms
screen in one-second intervals. Active alarms and pre-alarms can be viewed through BESTCOMSPlus
® .
The front panel Alarm LED is illuminated when alarms are active. When pre-alarms are active, the Alarm
LED flashes in one-second intervals.
If programmed and enabled, the horn output is closed when alarms are active. When pre-alarms are
active, the horn output toggles in one-second intervals.
Active alarms are also indicated on the optional remote display panel in the form of LEDs and an audible
horn. Red alarm LEDs light and the horn sounds when the corresponding alarm setting is exceeded. If an
active alarm condition is not annunciated by the remote display panel, the Switch Not In Auto LED lights
and the horn sounds.
Each alarm provides a logic output that can be connected to a physical output or other logic input using
BESTlogic
™Plus Programmable Logic.
A detailed list of alarms is provided in Table 6.
