Function The Xanbus AGS continuously monitors battery voltage and
starts, or stops, the generator when battery voltage drops below or exceeds
the preset limits. It also starts the generator to assist the system’s inverter/
charger when output power demands are high.

Start and Stop Triggers The Xanbus AGS requires a source of start and
stop triggers for automatic operation. The Xanbus AGS monitors the
Xanbus network and starts or stops the generator based on the preset limits
programmed into it.

975-0082-01-01 1

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.

2 Xanbus Automatic Generator Start (AGS) Owner’s Guide

Functions

Introduction

Generator Starting Triggers

The AGS can automatically start a generator in response to:

• a low battery voltage,

• large AC loads when inverter is operating,

• a thermostat signal, or

• a pre-programmed exercise period at a specified time of day.

Generator Stopping Triggers

The AGS can automatically stop a generator in response to:

• the introduction of qualified grid power (grid power within acceptable
parameters),

• high battery voltage,

• battery charge stage (float or absorb stage),

• reduction in AC loads when inverter is operating,

• a thermostat signal, or

• a pre-programmed quiet time period.

The AGS can also be used to manually start and stop the generator at any
time.

Programmable Features

Quiet Time The AGS features a quiet time setting, wh ich prevents the
generator starting at night or during other inconvenient periods.

Exercise Period During times of prolonged generator inactivity, the
AGS can be programmed to run (or “exercise”) the generator for a pre­defined period. This ensures the generator remains operational and that the
starting battery stays charged.

Status Reporting

The AGS reports its operating mode, its settings, generator activity, and the
reason for generator starts to the Xanbus system. This information can be
viewed on the Xanbus System Control Panel (SCP).

Installation Options

The AGS can be installed with an external shutdown input, a manual
generator ON/OFF switch, and an external ON/OFF indicator light.

Xanbus Automatic Generator Start Installation

Connecting the Generator

EQUIPMENT DAMAGE

Before connecting the AGS to your generator, read the Generator Type

descriptions in this section and consult your generator manufacturer to
ensure that Gen Type settings and connections are compatible with your
generator. Damage to the generator can result from selecting an inc o rre ct
Gen Type and following the connection diagram for an incorrect Gen
Type when connecting the AGS to the generator. Xantrex assumes no
responsibility or liability for loss or damage that might arise out of the use
of this information.

Failure to follow these instructions can damage the unit and/or
damage other equipment.

To connect the AGS to a generator , identify the start wiring configuration of
the generator to be used. Generators must be auto-start capable, and
generators equipped with remote operation connections are ideal.

If the generator is equipped for remote operation, examine the wiring of the
remote cable and connector (or read the generator’s documentation, if
available) and identify the following wires:

• Ground

•Start

•Stop

• Generator run signal, also known as the Hour Meter or Switched B+

Wiring Requirements Either #16 or #18 AWG wire is required to
connect to the wiring harness. How many of these wires you connect and in
which combination depends on your generator type.

Generator Types The AGS has 14 preset generator configurations, or
“Gen Types” (see “Gen T ype” on page 42). After installing the hardware, it
will be necessary to select one of these Gen Types from the AGS
Configuration Menu on the Xanbus System Control Panel (SCP).

IMPORTANT:

The following section describes the preset generator configurations and

provides diagrams for connecting the wiring harness to the generator’s start
wiring.

IMPORTANT:

Type 2

Type 2 is a three-wire GlowStop configuration recommended for “three­wire” generators that don’t require a dedicated preheat signal. In this
configuration, the start signal is applied for longer because the generator
does its own preheat and cranking while the start signal is applied.

Type 3

Xanbus Automatic Generator Start Installation

Type 3 is a three-wire GlowStop with shutdown bypass configuration. The
configuration shown in Figure 9 uses a shutdown bypass output to
temporarily disable the generator’s low oil pressure shutdown functionality
during cranking. Generators with this functionality often have a manual
means of disabling it during cranking.
