DGC-2020ES Engine Sender Inputs
In a Grounded Delta configuration where one phase (A, B, or C) of the delta connection is grounded, it is
likely a Voltage Sensing Fail condition will occur.
In Delta connected systems where the DGC-2020ES neutral input is not connected, it is uncertain which
line-to-neutral voltages will be monitored by the DGC-2020ES. Spurious Voltage Sensing Fail
annunciations could occur.
It is recommended that Phase Imbalance detection be used to detect sensing issues in Delta and
Grounded Delta configurations.
