A - Menu/Programming Navigation Buttons — See Menu

section for details

B - Mini USB Port — Authorized Dealer Service Use Only

C - Generator Operation Control Buttons —

 tiAUTOwNormal operating position. Press and hold button to put unit into Automatic mode. If an utility power outage is sensed, the system will start the generator. When utility power is restored, auto lets the engine stabilize internal temperatures, shuts off the generator, and waits for the next utility outage.

 tiOFFwTurns off running generator, prevents unit from starting, and resets any detected faults.

OFF must be pressed and held for more than 5 seconds in order to reset service codes.

 tiMANUALwUsed to manually start the generator.

“AUTO” LED — LED will light when unit is placed into Auto mode. LED will blink if exercise cycle is not set or set to OFF.

D – 15 Amp Fuse — Protects the home generator DC control circuits. If the fuse has ‘blown’ (melted open) or was removed, the engine cannot crank or start. Replace the fuse using only an identical ATO 15A fuse. One spare fuse is supplied with the unit.

E - Cover — This protective cover must be opened to access the fuse and the USB port.

F - Digital Display — Displays generator mode, menu options, service codes, and service engine indicators

More information may be found in Controls in the operator’s manual.
