f) Discontinue Power Delivery with Unit Shutdown
1) Normal
conditions
Push the Output ON/OFF pushbutton next to the lit green LED indicator to open the output load
contactor. The indicator light next to the button will go OFF, indicating the load contactor has
opened and power is no longer being delivered to the aircraft.
Once all contactors are opened:
a) If Idle Mode option is active (default), the generator will turn off and the engine will return to
idle speed after a 5 second delay.
b) If Idle Mode is inactive, the generator will turn off and the engine will remain at rated speed.
c) Pushing the engine Start/Stop pushbutton once while the engine is running begins the
automatic shutdown sequence which will shut off the engine after 30 seconds.
d) If the Engine Shutdown option is active, ten minutes after all outputs are opened (OFF) the
engine will slow to idle speed and 30 seconds later it will shut down.
2) Emergency

a) Depress
the
“
EMERGENCY STOP BUTTON
” located on front of the unit to the right of the
control panel. When pushed, this button shuts the generator set off. Pull the button back
out to reset it before restarting the generator set.
CAUTION
Do not use the “
EMERGENCY STOP BUTTON
” as a normal shutdown device.
Damage to the engine turbo charger may result without proper cooling time. Use the
Engine ON/OFF pushbutton for all normal engine shutdowns.
b) A condition of over-voltage, under-voltage, under-frequency, over-frequency, or overload in
the output circuit will automatically open the load contactor and display a fault code to
signal the operator which of the above faults caused the protective monitor system to
operate. After the fault has been corrected, press the respective output pushbutton to reset
the system. Proceed with power delivery by pressing the same switch.
g) Low Fuel Warning and Fault
1) A Low Fuel Warning occurs when the unit is running and fuel levels drops below 10% in the fuel
tank. The unit will continue to operate until it is out of fuel or the operator shuts off the engine.
2) A Low Fuel Fault will display if the fuel level is below 10% and the engine is off. The engine can’t be
started until the fuel level is above 10%.
h) Display
1) The display will automatically turn off if the engine has been off at least 10 minutes. Pushing any
button will return the display to full brightness. However, if there is a warning or fault message on
the display, it will not turn off.
