THEORY OF OPERATION Continued
AC POWER OUTPUT
The AC output system consists primarily of the AC generator, the output load terminal board, the voltage reconnection
terminal board, the main load contactor and the AC CIRCUIT INTERRUPTER switch on the EMCP. Power created by the
AC generator is supplied through the voltage reconnection terminal board and the main load contactor to the output load
terminals on the output load terminal board. The voltage reconnection terminal board allows configuration of the generator
set for 120/208 volt connections or 240/416 volt connections. The AC CIRCUIT INTERRUPTER switch located on the
EMCP closes and opens the main load contactor. This enables or interrupts the power flow between the voltage
reconnection terminal board and the output load terminals. The main load contactor is also opened automatically during any
of the specified set faults. The DVR module in the EMCP senses AC generator output voltage and provides excitation
voltage to the AC generator to maintain the desired output voltage. The VOLTAGE adjust potentiometer is connected to the
DVR to allow the operator to adjust the voltage. The operator can use the GSC keypad AC METER key to select which
output load terminals to monitor for current and voltage measurements. The values and terminals are indicated on the upper
and lower displays.
