Controller Fault Diagnostics

This table provides descriptions of the system events and their types—warning, shutdown, status, and notice.
Warnings show yellow fault lamp and signal an impending problem. Shutdowns show red fault lamp and stop the generator
set. Status is an event that is not an alert but is part of the event history. Notice is an alert that is NOT part of the event history.
System events are available as a Relay Output as shown.
Throughout this manual there are examples of the display text. In some cases, the message words and phrases are abbreviated
or shortened to accommodate the number of characters in the 12 x 2 digital display. See the following table for a full description
of the system event display messages.
