2.6 Faults

Selected fault conditions are shown in Figure 2-5. Fault
conditions are classified as warnings or shutdowns. If a
fault occurs that is not listed in the table, contact an
authorized distributor/dealer for service.
Note: All ECM faults are grouped under one listing in
Figure 2-5.
If a programmable interface module (PIM) is connected
to the generator set controller, additional faults can be
activated by customer-supplied equipment. See
TT-1584, Installation Instructions for the Programmable
Interface Module, for available inputs and outputs.
2.6.1

Warnings

The controller displays a fault message but the
generator set does not shut down on a warning. The
controller resets automatically after a warning condition
is corrected.
2.6.2

Shutdowns

Under a fault shutdown condition, the generator set
shuts down automatically and the controller displays a
fault message. The OFF LED flashes. See Figure 2-5.
Shutdown switches (such as the low coolant level
switch or high engine temperature switch) on the
generator set will automatically reset when the problem
is corrected. However, the fault condition at the
controller does not clear until the controller is reset.
The generator set cannot be restarted until the fault
condition is corrected and the controller is reset. See
Section 2.6.4 to reset the controller after a fault
shutdown.
