OVERSPEED PROTECTION SET POINT VERIFICATION
Determine desired set point frequency.
Maximum engine RPM is 2100. To determine maximum engine set point, add
approximately 10 percent, or 200 RPM. This will shut engine down at 2300
Determine mini generator's RPM at engine RPM set point.
Connect temporary jumper wire (Figure 6, Item 1) between terminals 2 and 5.
Figure 6. Jumper Terminals.
Convert the frequency set point to RPM by multiplying by 0.67 which will provide the test set point in RPMs.
Remove all jewelry before conducting maintenance. Do not wear watches, rings,
identification tags, or other jewelry which could short across electrical components or catch
on vehicle components. Failure to comply may result in personnel injury or death.
Apply power to speed switch.
Connect DC voltmeter between terminals 2 and 6.
Connect common lead of voltmeter to terminal 2.
Connect positive lead of voltmeter to terminal 6.
