Some sets are equipped with Barber-Colman Dyna
70025 electronic governor used in conjunction with a
Stanadyne D Series injection pump. This particular
setup uses different governor controllers for a
nonparalleling generator set or a paralleling generator
set. The system consists of a magnetic pickup, an
electronic control unit, and an actuator. The magnetic
pickup monitors engine speed and transmits this
information to the electronic control unit.
