The typical application is where the GAC auto sync and load sharing system is to be used with the 8290 engine speed control. The module accepts a nominal 5.0V DC signal and provides a 1.5V DC signal output to the 8290 control. DC power for the module is supplied from the 24V DC battery that powers the 8290 control. Wiring See Wiring Diagram. Note: The common battery minus connection between the 8290, EAM 108, and the GAC auto-sync and load sharing system should be as direct as possible electrically (minimum voltage difference).
