OOVEllNOR'7" '!'he ~yernor c9ntrols the speed of' the eng.ine, and therefore
'the Yoltageand frequency of the current. Proper governor adjustment
may be made as follows, referring toFig~ C.' Use a voltmeter While
making
the adjustments.
1. With the engine stopped, and tension on the ~yernor spring., adjust
the. governor linkagelengtQso that the carburetor throttle stop lever
clears the stop pin by not less than 1/64- as shown.
2. Start the plant and allow it to reach operating temperature.
3. With no electrical load connected, adjust the speed screw to the
point Where the voltage is approximately 126 volts for a 115 volt AC
plant, or 121 volts for a DC plant. Apply a full load to the plant
and check the voltage. It shouldbe approximatelyl08 volts for a
11.5 volt AC plant, or 110 volts for a DC plant. Voltages will be pro-
portionally higher for 230 volt plants, or lower for 208 volt plants. .
Jihgine
speed, as checked with a tachometer should bjil within the limits
of 1890 r.p.m.. at no load to 1745 r.p.m. at full load for an AC plant.
The DC plant engine speed should be within 1800 r.p.m. and 2000 r.p.m.,
with a spread between no load and full load of not more than 100 r.p.m.
4. If th~ plant tends to hunt .(alternately increase and decrease speed)
under load conditions, increase very slightly the distance between the
eye of the sensifivity screw and its support~ For best regulation keep
the screw in as close as possible without causing hunting. ANY. CHANGE
IN THE SETTING OF THE SENSITIVITY SCR1'W WILL REQUIRE CORRECTING THE
SPEEDSCRBW ADJUSTMENT.
5. If hunting occurs at NO LOAD, screw the small bumper screw in until
the hup.t is stopped, but not far enough to increase the engine speed.
CAUTION: Be sure all load is removed when adjusting the bumper screw.
Be sure that all lock nuts are tightened a.s adjustments are completed.
The governor can not operate properly if there is any binding, sti~kingt
or excessive looseness in the connecting linkage or carburetor throttle
asaembly.Alean fuel mixture, or a. cold engine inay cause hunting. If
the voltage drop is excessive when a full load is applied, and adjust- -
menta
are correctly made t it is probable that the engine is low on power
and
should be repaired as necessary.
