Frequency
The frequency settings allow selection of the rated frequency of the generator and an alternate frequency.
Rated Frequency of the Unit
Rated frequency settings consist of 50 and 60 Hz.
Alternate Frequency
This setting accepts values from 10 to 450, in increments of 0.01.
Battery Volts
The nominal voltage of the starter battery is used by the DGC-2020ES to detect and annunciate battery
overvoltage and low or weak battery voltage. The Battery Volts settings consist of 12 V and 24 V.
Generator Connection
Genset connection types accommodated by the DGC-2020ES include three, three-phase connections
(delta, wye, and grounded delta) and a single-phase configuration (sensing across phases A and B.)
Bus Connection
Bus connection types consist of single- and three-phase. Single-phase bus voltage is sensed across
phases A and B.
