3. FUNCTIONAL DESCRIPTION
3.1 ACTUATOR
The actuator consists of an electro-magnet with an iron
armature rolling on the center shaft bearings. The actuator is
provided with a return spring which balances the magnetic
force of the armature. When DC current flows in the coil, the
magnetic force tends to move the armature in the stator and
this linear motion is transformed into rotary motion through a
crank arm that forms part of the output shaft.
3.2 CONTROLLER
The electronic controller is the information processing unit of
the governor assembly. It contains electronic components
which process the input signal from the magnetic pickup and
control the engine to the desired speed/RPM set into the
controller. Electronic adjustments are available on the control-
ler for field adjusting the unit as necessary.
3.3 DC POWER SOURCE
The governor system receives its power from a battery or an
AC to DC power supply supplying 12 or 24 VDC
±
20% to
match the governor voltage. The average operating current
consumption is 2.5 to 3.5 amperes and the highest consump-
tion is 14.75 amperes during engine start-up or during a large
load change. The power source must be rated above maxi-
mum stall current.
3.4 COMPONENT LOCATION
The actuator of the governor assembly is mounted on the
engine next to the fuel system. The magnetic pickup is
normally mounted in the flywheel housing in such a way that
it can count the teeth on the starter ring gear. The controller is
off-mounted or installed in the engine control panel or cabinet.
