Programmable Functions
Any of the seven contact inputs can be programmed to recognize any one of 10 function types:
• Automatic Transfer Switch (ATS) - Start and run the generator while the ATS input is true and the
DGC-2020ES is in Auto mode.
• Grounded Delta Override - Uses Grounded Delta sensing if the generator connection is set for
Delta.
• Battle Override - The alarms programmed to shut down the unit will be overridden and ignored.
When a Battle Override condition is true the DGC annunciates a Battle Override Pre-alarm that is
recorded in the event log. If an alarm occurs while a Battle Override condition is true, the alarm
annunciates on the DGC front panel and is recorded in the event log, but the engine will not stop.
• The DGC monitors engine RPM during battle override. If the engine RPM drops to zero while an
alarm is active during a Battle Override condition, the DGC will proceed to issue a normal
shutdown to prevent fuel flow while the engine is not running.
• Low-Line Override - The 51, 27, and 59 settings are scaled by the low-line scale factor setting.
• Single-Phase Override - The unit switches to single-phase sensing configuration and uses the 1
Phase Override Sensing setting (A-B or A-C).
• Emergency Stop – When an input is assigned to the Emergency Stop Programmable Function,
the input functions in a normally-closed manner. When the input is closed, no alarm is
annunciated. When the input is open, the DGC-2020ES will open the Start, Run, and Prestart
relays and annunciate an Emergency Stop Alarm.
Once an input is assigned to this programmable input, navigate to Settings Explorer >
Programmable Inputs > Contact Inputs and configure the following settings:
° Alarm Configuration: Status Only
° Activation Delay: 0
° Label Text: Any text is acceptable.
° Contact Recognition: Always
