Control Board
The control board is used on MUI engines only. The control board is the main component of the control panel for the MUI engine. The control board performs numerous generator set control functions. The following connectors are used in order to make electrical connections to the other generator set components: the spade terminals, the 24 pin connector and other connectors. The control board contains numerous switches and potentiometers for adjustments of the different functions. The eight light emitting diodes act as fault indicators for service personnel. For more detailed information, see Systems Operation, "General Information".
