72 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Troubleshooting
Fault Reference Table
When the AGS detects a fault condition, it stops the generator. The red
Fault light also comes on, and the Xanbus System Control Panel (SCP)
displays a fault message.
The AGS remembers the GenMode that it was in at the time it detected the
fault. After you have cleared the fault, the AGS returns to its last known
GenMode.
