5. See Troubleshooting (Page 22) if the engine
shuts down and the status indicator light blinks.
6. Always secure the access cover after starting
the genset at the genset control panel.
WARNING
Operating the genset with the
access cover off can lead to severe burns
and overheating of components. Always
secure the cover after starting the genset.
STOPPING THE GENSET
Turn off the air conditioner and other large
appliances and let the genset run for two minutes to
cool down before stopping. This reduces backfiring
and run-on. Then press the switch to STOP to stop
the genset.
RESTARTING THE GENSET
See Troubleshooting (Page 22) if the genset shuts
down abnormally.
LOADING THE GENSET
The genset can power AC motors, air conditioners,
AC/DC converters and other appliances. How much
appliance load* can be powered depends upon the
genset power rating. The genset will shut down or its
circuit breakers will trip if the sum of the loads
exceeds genset power.
To avoid overloading the genset and causing shut-
downs, compare the sum of the loads of the
appliances that are likely to be used at the same
time with the power rating of the genset. Use Table 2
or the ratings on the appliances themselves (if so
marked) to obtain the individual appliance loads. It
may be necessary to run fewer appliances at the
same time—the sum of the loads must not be
greater than genset rating.
Note that the genset may shut down due to over-
load—even though the sum of the loads is less than
genset rating—when a large motor or air conditioner
is started last or cycles off and then on again. The
reason for this is that a motor’s startup load is much
larger than its running load. It may be necessary to
run fewer appliances when large motors and air
conditioners are cycling on and off.

Electric Blanket 50-200
Note also that air density decreases as altitude in-
creases, causing rated genset engine power to de-
crease—approximately 3.5 percent each increase
of 1000 feet (305 m) above the maximum elevation
at which the engine can maintain rated power
(Table 3). It may be necessary to run fewer
appliances at higher altitudes.
De-rating for temperature usually is not necessary
because the engine can maintain rated power in
ambient air temperatures of up to 120° F (49° C).

1. − This table does not take into account the effect circuit
breakers may have in limiting maximum genset power. Also,
power decreases even though the altitude adjust knob is set
correctly (Page 11).
* Appliance load and genset power are measured in terms of watts (W) or kilowatts (kW), where 1 kilowatt (kW) = 1000 watts (W).
