(3) Engine Idle Mode
When the engine has been started, the engine will begin in the idle mode. The ENGINE START
push-button will flash indicating the engine is in the idle mode.
(4) Engine Run Mode
After the engine has been warmed up properly in the Engine Idle Mode, pressing the ENGINE
START push-button again brings the GPU up to rated speed. The ENGINE START push-button
light no longer flashes, but instead becomes continuously illuminated. The GPU is now ready for
aircraft loading.
(5) Engine Shutdown Mode
When shutting the GPU down, pressing the ENGINE STOP push-button starts the 3-5 minutes
delayed shutdown period. The ENGINE STOP push-button flashes and the engine returns to idle
speed. The shutdown period is required to cool the engine's turbocharger.
(6) Engine Stop Mode
After the 3-5 minutes delayed shutdown period, the engine stops running.
(7) System Off Mode
The power is removed from the GPU's entire control system.
b) Faults
Faults result when any of the fault limits are exceeded, when an internal problem occurs, or under
certain conditions that would cause injury to personnel or damage to an aircraft or the GPU. Faults
are also stored in memory as event records. The fault limits and conditions are preset at the factory.
