2 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Introduction
System Requirements
Minimum basic system components include the following:
❐ Freedom SW Series Inverter/Charger
❐ AC Generator or DC Generator
❐ Xanbus System Control Panel (SCP)
❐ Xanbus Automatic Generator Start (AGS)
Network Communication Protocol The AGS uses Xanbus, a network
communications protocol developed by Xantrex, to communicate its
settings and activity to other Xanbus-enabled devices. All network
components used in the system must be Xanbus-enabled.
Network Power Supply The Xanbus AGS requires three watts of power
(maximum) to operate. This power supply is provided by the Freedom SW
Series Inverter/Charger through the Xanbus network.
Generator The generator should be a 2-wire or 3-wire generator with
Auto Start capability.
The generator should also supply a Generator Run signal. The Generator
Run signal is connected to the Xanbus AGS and used by the Xanbus AGS
to detect whether the generator is running. Some generator manufacturers
refer to this signal as the Hour Meter Signal or Switched B+.
Connecting the Generator Run signal is optional and only used for
redundancy. The Xanbus AGS requests generator voltage from the Xanbus
in addition to checking the Generator Run signal to detect if the generator is
running.
Generator Compatibility The Xanbus AGS supports most two and
three-wire generator starters. Some manufacturers include, but are not
limited to, Onan (Quiet Diesel, gasoline, and LP), Power Tech, Generac,
Northern Lights, Fisher Panda, Westerbeke, Kohler, Honda, and Yamaha.
Check with the generator manufacturer to ensure the generator in question
includes automatic starting capabilities.
Xanbus System Control Panel (SCP) A Xanbus System Control Panel
(SCP) is required to configure the AGS and monitor generator starting and
stopping activity.
The Xanbus System Control Panel (SCP) also provides real-time clock
information for the AGS Quiet Time and Exercise Time features.
