(FC_6) ENGINE OVERSPEED
The control panel monitors generator output frequency
at Wires #E1 and #E2. If the generator output
frequency increases to 65Hz-70Hz, the control panel
waits three seconds before shutting the unit down.
Should the frequency exceed 70Hz, the control panel
will shut down the generator immediately. If the
governor top speed is adjusted too high, the generator
will shut down immediately after starting.
The reason for the 5Hz latitude in frequency sensing is
that the engine governor will hunt somewhat before it
finds the desired setting. This causes variable
frequency outputs that are not harmful until they reach
the 65Hz-70Hz range.
If the control panel senses an over-frequency
condition, the digital display will show
FC_6
and the
remote LED will repeatedly flash six times with a
pause.
The troubleshooting steps for under - and over-
frequency faults are identical.
Note that over-frequency is a symptom of a governor
related issue. Refer to
Single Cylinder OHV Repair
Manual (#276781)
for procedures to check the
adjustment and/or repair of the engine governor.
