Troubleshooting Guide

Diagnostic:

The  Command  &  Control  Center  will  display  certain  faults  that  can  assist  a  service
technician  in  trouble  shooting  a  problem  with  the  generator  system.    When  these  faults
occur,  the  fault  message  will  periodically  flash  on  the  Command  &  Control  Center,
interrupting the normal display. Reference

Error! Reference source not found.

30 for an e

xample of an over-current fault.

The faults can also be accessed by repeatedly pressing the mode switch.  After displaying
the oil temperature, oil filter time, and configuration, the next display will be the first active
fault.  Each time the Mode switch is pressed; the next fault will be displayed.  When there
are no more faults to display, the Command & Control Center will return to Normal mode.
