When enabled, this feature allows the DGC-2020HD to automatically detect its sensing configuration in
relation to the generator. Upon starting the genset, the configuration of the generator is automatically
detected. Single-Phase Override and Low-Line Override statuses are set accordingly.

There is a one-second delay in the detection to prevent the DGC-2020HD from alternating between
detected configurations. When the DGC-2020HD is in the Off mode or the engine is not running, the
Automatic Configuration Detection function is disabled. The DGC-2020HD is assumed to be in the last
valid automatically detected configuration.

It is recommended that the Single-phase Override and Low-line Override programmable functions are not
assigned to contact inputs when Automatic Configuration Detection is enabled.

The BESTCOMSPlus Auto Config Detection screen is illustrated in Figure 176. Settings are listed in
Table 79.

Single-phase Detect Threshold

If the difference between the maximum and minimum line-to-line voltage exceeds this threshold, the unit
is determined to be in single-phase configuration. If determined to be in single-phase configuration, the
Single-phase Override programmable function forces the DGC-2020HD into single-phase mode. The
single-phase mode connection is determined by the Single-phase Detect Generator Connection, below.

If the Single-phase Override function is assigned to a contact input via the Programmable Functions
screen, the state of the contact input and the detected configuration are ORed. This means, if one or both
are true, then the system is determined to be configured as single-phase.

Low-line Detect Threshold

If the average of the valid line-to-line voltages for the detected configuration meets or exceeds this
threshold, the unit is determined to be in a high-line configuration. If the average is below this threshold, it
