Configure the following parameters:
1. Auto Transfer Switch
a. Input - This function is used to start the generator from a contact input when the DGC-2020 is
in AUTO mode. Select the desired input or select None to disable the programmable function.
b. Contact Recognition - Select Always.
2. Grounded Delta Override
a. Input - If a reconfigurable machine will operate sometimes in a grounded delta configuration
and sometimes in other configurations, select an input for this function to indicate to the
DGC-2020 when the machine is in the grounded delta configuration. When the machine is
grounded delta, the DGC-2020 will display line-to-neutral as well as line-to-line voltages. In
normal delta, the line-to-neutral voltages are not displayed. Select None to disable the
programmable function.
b. Contact Recognition - Select Always.
3. Battle Override
a. Input - Select an input for this function if a battle override initiated from a contact input is
required. For some very critical applications, the ability to remove all system shutdowns may
be a requirement. Selecting battle override will prevent all alarms from stopping the engine.
Extreme caution should be taken before selecting this option as machine warranties can be
voided if enabled. Select None to disable the programmable function.
b. Contact Recognition - Select Always.
4. Low Line Override
a. Input - If a reconfigurable machine will operate sometimes in a low line configuration machine
and sometimes as high line, select an input for this function to indicate to the DGC-2020 that
the machine is in low line operation. When this is in effect, the Low Line Scale Factor settings
(found in various protection elements and bus stable/failed detection elements) will be
applied to the metered parameter used for the protection. Select None to disable the
programmable function.
b. Contact Recognition - Select Always.
5. Single-Phase Override
a. Input - If a reconfigurable machine operates sometimes in a single-phase configuration and
sometimes as three-phase, select an input for this function to indicate to the DGC-2020 that
the machine is in single-phase operation. When this is in effect, single-phase settings apply in
the generator protection elements and only single-phase voltages and currents are displayed
on the front panel. Select None to disable the programmable function.
b. Contact Recognition - Select Always.
c. Single-Phase Override Sensing - If the machine connection type is not reconfigurable,
disregard this setting. However, if a machine is a reconfigurable machine, this setting defines
how to interpret a single-phase override contact input. Refer to the appropriate paragraphs in
Section 4, BESTCOMSPlus
® Software, for additional information.
6. Single-Phase AC Override
a. Input - If a reconfigurable machine operates sometimes in a single-phase AC (as opposed to
single-phase AB) configuration and sometimes as a three-phase or single-phase AB
configuration, select an input for this function to indicate to the DGC-2020 that the machine is
in single-phase AC operation. When this is in effect and the single-phase override is in effect,
single-phase settings apply in the generator protection elements and the metering uses
phase C current and phase AC voltage for power factor calculations. Otherwise, phase A
current and phase AB voltage are used for power factor calculations. Select None to disable
the programmable function.
b. Contact Recognition - Select Always.
7. Battery Charger Fail
a. Input - Select an input for this function to indicate a battery charger failure. When this input is
true, an alarm or pre-alarm will be annunciated based on alarm configuration, and the Battery
Charger Fail indicator on the RDP-110 (Remote Display Panel) will illuminate. Select None to
disable the programmable function.
