Diesel Generator Operation Manual TROUBLESHOOTING Part 1
Introduction&Control Unit DC Power Supply
Fault code tables together with Warning and Shutdown code tables are provided in this section to assist in locating and identifying the possible causes of faults in the generator set system.
7.2 Control Unit DC Power Supply
The generator set control continuously monitors engine sensors for abnormal conditions, such as low oil pressure and high coolant temperature. If any of these conditions occur, the control will light a yellow Warning lamp or a red Shutdown lamp and display a message on the graphical display panel.
In the event of an engine shutdown fault (red Shutdown lamp), the control will stop the engine immediately; for an alternator shutdown fault, the engine will stop after the Cool–down Timer has timed out. If the generator set is stopped for this reason, the operator can restart the set after making the necessary adjustments or corrections. This section lists the Warning and Shutdown codes/messages (Table 7–1), and suggests troubleshooting procedures (Table 7–2).
Note: Displayed error codes that are not listed in Table 7–2 will require an authorised service representative to correct the fault. Contact an authorised distributor for assistance.
