Table 1. Control and Indicator Descriptions
Green Display Panel On LED lights when control power is applied to the RDP-110C.
Green EPS Supplying Load LED lights when the genset is supplying more than 2% of rated
load.
The horn sounds when an alarm or pre-alarm exists or the connected DGC is not operating in
Auto mode. The horn is silenced by pressing the Alarm Silence pushbutton (locator E).
The amber Pre-Alarm LEDs light when the corresponding pre-alarm setting is exceeded.
Conditions annunciated by the pre-alarm LEDs include:
• High coolant temperature,
• Low coolant temperature,
• Low oil pressure,
• Low fuel level,
• Weak battery,
• Battery overvoltage, and
• Battery charger failure.
When the RDP-110C is used with a DGC-2020, the bottom two LEDs (Battery Overvoltage and
Battery Charger Failure) can be reprogrammed to indicate other pre-alarm conditions. See
Programmable Alarm and Pre-Alarm Configuration for information about configuring the two
programmable pre-alarm indicators.
RDP-110C controls consist of two pushbuttons.
• The Alarm Silence pushbutton silences the horn (locator C).
• The Lamp Test pushbutton can be used to verify operation of all RDP-110C LEDs and
The red Alarm LEDs light when the corresponding alarm settings are exceeded. Conditions
annunciated by the alarm LEDs include:
• Low coolant level,
• High coolant temperature,
• Low oil pressure,
• Overcrank,
• Overspeed,
• Emergency stop activated,
• Fuel leak/sender failure, and
• Sender failure.
When the RDP-110C is used with a DGC-2020, DGC-2020ES, or DGC-2020HD, the bottom
two LEDs (Fuel Leak/Sender Failure and Sender Failure) can be reprogrammed to indicate
other alarm conditions. See Programmable Alarm and Pre-Alarm Configuration for information
about configuring the two programmable alarm indicators.
Red Switch Not in Auto LED lights when the DGC is not operating in Auto mode.
PROGRAMMABLE ALARM AND PRE-ALARM INDICATOR CONFIGURATION
When used with a DGC-2020, DGC-2020ES, or DGC-2020HD, the RDP-110C has the added capability of
programmable alarm and pre-alarm indicators. This ability applies only to the DGC-2020, DGC-2020ES, or DGC-
2020HD and is not available when the RDP-110C is paired with the DGC-500 or DGC-1000.
Up to two alarm LEDs and two pre-alarm LEDs may be reprogrammed to suit the needs of a particular
application. The two bottommost alarm LEDs are preconfigured in DGC logic to annunciate a fuel leak/sender
failure and sender failure. The two bottommost pre-alarm LEDs are preconfigured in DGC logic to annunciate
battery overvoltage and a battery charger failure. These LEDs are labeled as such with replaceable cards (Figure
4) that can be relabeled to match the function of each programmable indicator.
