Resetting the SI Controller Board
1.
To reset the SI controller board, wait 10 seconds after the red light turns on, then
press the on-board reset switch. If the pressure switch is still closed, the SI controller
board will energize the SI and the SI will begin another three start trials.
2.
If the optional TEG Controller board is installed;
Press the Reset (S3) or send a SCADA Reset signal to the TEG Controller board.

Burner
The burner conveys gas from the fuel system, mixes it with air and transports the mixture
to the combustion zone. Air passes through a flame arrestor, screening out insects and dust,
and then through a venturi and air-shutter assembly allowing for adjustment of the air/fuel
mixture. This mixture leaves the venturi and passes through a burner screen that anchors
the flame. Combustion chamber format enables the uniform heating of the power unit hot-
end. The main parts of the burner are shown in Figure 5.

Power Unit
The power unit generates electric power from the direct conversion of heat energy into
electrical energy. A temperature difference maintained across the power unit effects voltage,
and power output. A burner maintains the hot side at a temperature of around 538ºC
(1000ºF). Cooling fins, which transfer the heat to the surrounding air, maintain the cold side
at a lower temperature of around 163ºC (325ºF). Adjusting the amount of fuel supplied to
the burner varies the temperature difference and controls the power output.
