A. USB PROGRAMMING PORT - USB port for computer
interface. Used for programming the DSE7310 controller.
B. DSE7310 CONTROLLER - See controller explanation.
C. Emergency Stop Switch - When depressed this switch
will disconnect all the 12 volt power to the DSE7310 shutting
the engine down. The display on the controller will annunciate
“Emergency Stop”.
D. AC INTERFACE CONNECTOR - This connector is used to
interface with the AC generator end. It provides the controller
with the voltage, amperage and frequency reading for the
display.
E. DC INTERFACE CONNECTOR - This connector provides
all the interface connections for the engine. Including the DC
power supply to operate the DSE7310 controller. Engine ECU
connections are also made through this connector providing the
controller with the engine operational reading.
F. 10 AMP FUSE This fuse supplies the DSE7310 controller 12
Volt DC for all controller functions. (Replacement ATO-ATC 10A-
250V)
G. 3 AMP FUSE -This fuse is in the power supply for the
DSE7310 controller circuitry on the board. (Replacement ATO-
ATC 3A-250V)
