Manual 82329
Each Woodward Electrically Powered Governor (EPG) system includes three
basic parts:
•
A magnetic pickup (MPU) which senses engine speed from an engine-
driven gear.
•
A speed control which receives the speed signal from the MPU, compares it
to a reference signal, and generates a control signal which the control sends
to the actuator.
•
An actuator which receives the signal from the control and positions its
output shaft according to this signal. The output shaft is linked to the fuel
control.
There are two EPG models:
•
The isochronous speed control, which is available with start-fuel limit or dual
dynamics;
•
The droop speed control, which includes a load sensor and provides droop
control for generator sets.
Different actuator sizes are available for different work output requirements.
Models are available for either 12 or 24 volt systems.
