will be driven to the maximum value of the voltage regulator analog bias output range. If the value
is 0.000, the output will be driven to the midpoint value (i.e. half way between maximum and
minimum values) of the voltage regulator analog bias output range. If the generator breaker is
open, or if the generator breaker is closed and kvar control is disabled, the Volt Bias value will be
0.00, driving the bias output to the midpoint of the voltage regulator analog bias output range
indicating the voltage regulator should operate the generator at rated voltage.
AEM-2020
This screen shows the binary data that is being sent between the AEM-2020 (Analog Expansion Module)
and the DGC-2020HD.
The AEM diagnostics screen is located on the front panel at Metering > Diagnostics > AEM.
The following parameters are visible on the AEM diagnostics screen:

DGC To AEM BP: DGC-2020HD to AEM-2020 Binary Points. This is a 32-bit, bit packed number
representing the binary points transmitted from the DGC-2020HD to the AEM-2020. Debug at this
level is not necessary.

AEM To DGC BP: AEM-2020 to DGC-2020HD Binary Points. This is a 32-bit, bit packed number
representing the binary points transmitted from the AEM-2020 to the DGC-2020HD. Debug at this
level is not necessary.
CEM-2020
This screen shows the binary data that is being sent between the CEM-2020 (Contact Expansion Module)
and the DGC-2020HD.
The CEM diagnostics screen is located on the front panel at Metering > Diagnostics > CEM.
The following parameters are visible on the CEM diagnostics screen:

DGC To CEM BP: DGC-2020HD to CEM-2020 Binary Points. This is the status of the CEM-2020
output relays being transmitted from the DGC-2020HD to the CEM-2020. This is a 32-bit, bit packed
number representing the desired states of the CEM-2020 outputs. The left-most bit is the first output,
etc.

CEM To DGC BP: CEM-2020 to DGC-2020HD Binary Points. This is the status of the CEM-2020
inputs being transmitted from the CEM-2020 to the DGC-2020HD. This is a 32-bit, bit packed number
representing the metered states of the CEM-2020 inputs. The left most bit is the first input, etc.
