5) Special Features
The generator set has special features that are described more fully under the assemblies in which
they appear.
a) Protective
Monitoring
The protective monitoring system receives signals from the fault sensing components in the
generator output circuit and functions to cause the load to be disconnected from the generator if
an abnormal condition of voltage, frequency, or load develops. The nature of that abnormal
condition is then presented on the graphical display.
b) Voltage
Regulator
A microprocessor-type, adjustable voltage regulator provides automatic voltage regulation at the
aircraft. The regulated output is also adjustable for a variety of output cable sizes and lengths.
c) Engine Electronic Control Module (ECM)
The engine is equipped with an electronic control module (ECM) that monitors, records, and
controls engine performance.
d) Battery System Disconnect Switch
The generator set is equipped with a battery disconnect switch outside the unit on the RIGHT
side. The disconnect switch should be placed in the OFF position for long periods of shutdown.
NOTE: DO NOT disconnect the batteries when the engine is running or within two (2)
minutes after the engine stops.
