HIGH COOLANT TEMPERATURE SWITCH:
Normally open (N.O.) thermostatic switch has sensing
tip which is immersed in captive coolant. Should
coolant temperature exceed about 230°F (110°C), the
switch contacts close, which causes the engine to shut
down automatically (Figure 6).
Figure 6- High Coolant Temperature Switch
LOW COOLANT LEVEL SWITCH:
Should engine coolant level drop below the level of the
high coolant temperature switch, it is possible for the
engine to overheat without automatic shutdown.
prevent such overheating without automatic shut down,
the engine has a low coolant level sensor. If the engine
coolant drops too low, the engine automatically shuts
down (Figure 7).

OVERSPEED SHUTDOWN:
The CMA circuit board on liquid cooled units receives
AC frequency (rpm) signals directly from the stator AC
power windings, via sensing leads S15 and S16. Should
AC frequency exceed about 72 Hz, circuit board action
will automatically shutdown the engine (Figure 8).
*Rated power of generator is subject to and limited by
such factors as ambient temperature, altitude, engine
condition, and other factors. Engine power will decrease
about 3.5% for each 1000 feet above sea level and will
decrease an additional 1% for each 10°F above 60°F .
Maximum output power of the generator is limited by
maximum engine power.
