System
component
The Xantrex Automatic Generator Start (Auto Gen Start) automatically
starts and stops your generator using dry contact relays to operate the
auto-start function of your generator. (Dry contacts operate only as
switches. The Auto Gen Start does not provide any voltage or current to
the connections.)
The Auto Gen Start continuously monitors your power system and starts
the generator if the battery voltage or state of charge reaches preset limits,
or the air conditioner or heater needs to be run. The Auto Gen Start also
starts the generator to assist the inverter/charger when power demands are
high. When properly configured, the Auto Gen Start ensures that your
power requirements are met and that your batteries stay charged.
automatic generator starting when dry camping or when shore power is
otherwise unavailable.
The Auto Gen Start uses Xanbus™, a network communications protocol
developed by Xantrex, to communicate its settings and activity to other
Xanbus-enabled devices. You can configure and monitor the Auto Gen
Start and every Xanbus-enabled device in the system using a single
System Control Panel.
Xanbus-enabled products are:
•Easy to use. The Xanbus system simplifies operation and automates
routine tasks.
•Reliable. Software control eliminates errors due to analog signalling.
•Accurate. Digital information is less susceptible to interference and
line loss.
•Upgradable. Firmware upgrades mean your purchase will remain up
to date.

Introduction
System Requirements
The Auto Gen Start is not designed for stand-alone operation. It does not
function in a simple system containing only an Auto Gen Start and a
generator. The Auto Gen Start requires several other components for
configuration and operation.
GeneratorThe generator should have automatic starting capability.
Some manufacturers of generators without this capability may sell an
optional automatic engine control module that will simplify operation
with the Auto Gen Start.
The generator should also supply a Generator Run signal, which the Auto
Gen Start uses to detect whether the generator is running. Some generator
manufacturers refer to this signal as the hour meter signal or
Switched B+.
Control panelA separate control panel is required to configure the
Auto Gen Start and monitor generator starting and stopping activity. The
control panel also provides real-time clock information for the Auto Gen
Start Quiet Time and Exercise Time features.
Network power supplyThe Auto Gen Start requires a Xanbus power
supply to operate. Network power is carried by the network cables, and
can be supplied by a Xanbus-enabled product (such as an inverter/
charger) or an external Xanbus power supply.
As a device that draws network power, the Auto Gen Start consumes a
maximum of 3 watts.
Start and stop triggersThe Auto Gen Start requires a source of start
and stop triggers for automatic operation. These triggers can come from:
•thermostat 12/24 V input.
•battery voltage, state of charge, and inverter load status. This
information must be transmitted over the network by another Xanbusenabled device, such as an inverter/charger or DC Monitor.
When network-broadcast battery voltage, state of charge, and inverter
load information are not available, the Auto Gen Start could operate in a
reduced system with a control panel and network power supply. In this
system, the Auto Gen Start would be limited to automatically starting and
stopping the generator from thermostat 12/24 V input. In such a system,
you could also start and stop the generator manually using the control
panel, and Quiet Time, Exercise Time, and maximum run time settings
would function.

Installing the Auto Gen Start
Type 12 is a three-wire GlowStop configuration recommended for “threewire” generators that don’t require a dedicated preheat signal, such as
Onan propane generators. 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.

Connecting the thermostats (optional)
Wires 1, 2, 3, and 4 on the wiring harness can be connected to two
thermostats. Wires 1 (yellow) and 2 (gray) are intended for thermostat 1
and wires 3 (orange) and 4 (gray) are intended for thermostat 2.
These wires connect to 12/24 V output signals from the thermostats. You
can enable the Auto Gen Start to start the generator in response to these
signals. You cannot program your thermostats with the Auto Gen Start.
For specific information about thermostat wiring and where Auto Gen
Start connections should be made, please consult your thermostat
documentation or contact the thermostat manufacturer.
Connecting an external shutdown (optional)
Installing the Auto Gen Start
The external shutdown input is a 12/24V input used to assure that the
Auto Gen Start keeps the generator off under conditions that may be
potentially hazardous. Wire 5 (white/black) and 6 (gray) on the wiring
harness are intended for an external switch or sensor (such as a moisture
detector, carbon monoxide detector or coach running signal) that
produces an active high 12V or 24V output.
Connecting an external manual on/off switch (optional)
The external manual on/off inputs (wires 7 and 8 on the wiring harness)
are intended for wiring to one or more remote on/off switches for starting
and stopping the generator manually. The other contact of the switch
should be connected to ground. In order for the Auto Gen Start to be able
to detect these switches, you must wire the positive of the generator
battery to the constant 12V/24V generator battery positive (wire 10 on the
Auto Gen Start wiring harness). See Figure 2-12.
975-0082-01-012–23
Installation
If your generator battery does not have the required voltage, any 12V or
24V power source will suit this purpose. If an alternate power source is
used, the negative of the power source must be connect to the other
contact of the switch.

Multiple control panels or simple contact closures can be wired to the
external manual on/off inputs. The Auto Gen Start detects if any of the
contacts close and will change its operating mode to External Manual On
or External Manual Off (for more information, see “AGS Mode” on
page 3–9). The Auto Gen Start turns the generator on or off according to
these inputs and the resulting operating mode change.
Unlike the Manual On or Manual Off operating modes you can enter by
using the System Control Panel, the External Manual On and External
Manual Off states are not affected by maximum generator run time (see
“Max Run Time” on page 3–29).
Connecting an external on/off LED
Wires 9 (White/Blue) and 11 (Black) on the wiring harness can be
connected to an LED or other light to accompany a remote external on/off
switch. This light turns on when the generator run signal is active to
visually indicate that the generator is running.
Important::
during the preheat stage, before the generator is actually running. In this case, the
external on/off LED (and the Generator On light on the Auto Gen Start) will turn
on during the preheat stage and remain on when the generator is running.
For some generators, these lights will also remain on for a period of time after the
generator has stopped.

Connecting the control panel and other network-enabled devices
CAUTION:
Connect only to other Xanbus-enabled devices.
Although the cabling and connectors used in this network system are the same as
Ethernet connectors, this network is not an Ethernet system. Equipment
damage may result from attempting to connect these two different systems.
To connect the Auto Gen Start to a System Control Panel or another
network-enabled device, plug a Xantrex network cable or equivalent from
another device into one of the network connectors on the bo ttom p an el of
the Auto Gen Start. See Figure 2-1 on page 2–4.
If the Auto Gen Start is being installed on an existing Xanbus system, the
system must first be put into Safe mode. See “Changing System Modes”
on page 4–6.
Depending on the layout of the Xanbus system, you have the following
options for the other network connector on the Auto Gen Start:
•A second network cable (in a “daisy-chain” network layout)
•A network terminator (in a “daisy chain” network layout where the
Auto Gen Start is the last device at one end of the network)
•Nothing (in a multi-drop backbone layout)
Equipment damage
Verifying power is available
When the Auto Gen Start has been installed properly, the Power and
Network indicator lights turn on.
If one or both lights are out, check the network connections and ensure
the network power supply is on.

Configuration
Chapter 3 contains information and procedures for
configuring the Automatic Generator Start. It describes
how you can view the Auto Gen Start menu on the
System Control Panel, and how you can change Auto
Gen Start settings using the System Control Panel.
Chapter 3 also discusses each Auto Gen Start setting by:
•Defining each setting.
•Listing the available values for each setting.
•Recommending when to use each setting.
•Describing the effect of changing each setting.
Configuration
Configuring the Auto Gen Start
The Auto Gen Start has a number of settings that you must configure to
ensure that the generator automatically starts and stops under the right
conditions and at the right time.
If your Auto Gen Start was pre-installed in your Xanbus system, it may
already be configured to work with your generator and network-enabled
power system. If this is the case, you may not have to configure any
settings other than the Generator mode (see page 3–9) and Quiet Time
(see page 3–11).
Using the System Control Panel
The Auto Gen Start is configured using the System Control Panel. You
can view all the available Auto Gen Start settings on the System Control
Panel screen.
The System Control Panel has four navigation buttons that you use to
move between screens and menus, highlight settings you want to change,
and select values for the Auto Gen Start to use.
See Figure 3-1 and Table 3-1 for the location and function of the
navigation buttons on the System Control Panel.

When to useYou should change “AGS Mode” when you want to switch between
automatic generator control and manual generator control.
When the Xanbus system powers up all network-enabled devices, the
Auto Gen Start is in Manual Off mode. To enable automatic generator
starts, you must put the Auto Gen Start in Automatic mode.
AutomaticIf you would like the Auto Gen Start to start and stop the
generator automatically, select Automatic. The generator can start and
stop automatically in response to low battery voltage, low battery state of
charge (requires a DC Monitor in the Xanbus System), AC loads on the
inverter, thermostat triggers, or exercise time. Automatic mode also has a
Quiet Time feature, which prevents the generator from starting during
evening hours or other inconvenient times (see “QT Begin” on page 3–11,
“QT End” on page 3–13, and “Setting Quiet Time” on page 4–3).
WARNING: Fire and health hazard
Running a generator in an enclosed space produces potentially lethal exhaust
gases.
Before putting your RV or boat in storage, disable the Auto Gen Start by putting
the Xanbus system in Hibernate mode. Do not leave a generator connected to an
Auto Gen Start otherwise unattended.
Automatic
mode overrides
975-0082-01-013–9
When the Auto Gen Start is in Automatic mode, several settings and
conditions override automatic start and stop triggers. These overrides
include, in order of priority:
•Faults—The Auto Gen Start stops the generator when a fault occurs.
Configuration
•External Shutdown—When the Auto Gen Start is connected to a
sensor or meter (a moisture detector, for example) wired to contacts 5
and 6 of the 20-contact connector, it stops the generator when the
device is activated. See “Connecting an external shutdown
(optional)” on page 2–23.
•External On/Off—The generator is manually started or stopped with a
switch wired to contacts 7 and 8 of the 20-contact connector. See
“Connecting an external manual on/off switch (optional)” on page 2–
23. When started with an external manual on/off switch, the generator
will not stop when it reaches Max Run Time. You must stop the
generator using the external manual on/off switch.
•Max Run Time—When the generator has exceeded its maximum run
time, a warning message will appear on the System Control Panel.
The Auto Gen Start will stop operating until you acknowledge the
warning by pressing Enter on the System Control Panel. See “Max
Run Time” on page 3–29.
•Manual On—The generator is started by selecting Manual On mode.
•Manual Off—The generator is stopped by selecting Manual Off
mode.
Manual OnWhen you need to manually start the generator, select
Manual On. Selecting Manual On mode overrides the automatic start
settings and manually starts the generator. The generator will run until it
is manually stopped or until it reaches its Auto Gen Start-defined
Maximum Run Time (see “Max Run Time” on page 3–29).
Manual OffWhen you need to manually stop the generator, select
Manual off. Selecting Manual Off mode overrides the automatic stop
settings and manually stops the generator. You must select Manual Off to
stop the generator when the generator has been started manually. The
Auto Gen Start will not automatically start the generator again until you
select Automatic.
Important:
change any start trigger parameters.

“QT Enable” applies only when the Auto Gen Start is in Automatic mode.
ValueDescription
On, OffEnable or disable the Quiet Time functionality.
When to useWhen you need to use the Auto Gen Start Quiet Time feature, set “QT
Enable” to On, then check or reset the times you have set for “QT Begin”
and “QT End”.
When you have no preferences or restrictions for when the generator
should run, set “QT Enable” to Off.
OutcomesSelecting On enables the Quiet Time feature. If the Auto Gen Start is in
Automatic mode, the Auto Gen Start stops and starts the generator
according to the times you have set for “QT Begin” and “QT End”.
Selecting Off disables the Quiet Time feature. The Auto Gen Start will
ignore the times you have set for “QT Begin” and “QT End”. If the Auto
Gen Start is in Automatic mode, the Auto Gen Start starts and stops the
generator at any time of the day or night in response to battery voltage,
battery state of charge, inverter load, thermostat triggers, and exercise
time.
QT Begin
Full nameQuiet Time Begin
Purpose“QT Begin” is a changeable setting that defines the start of quiet time.
This setting also requires you to set “QT End”.
ValueDescription
12:00AM to 11:59PM
(12-hour clock)
00:00 to 23:59
(24-hour clock)
When to use“QT Begin” functions only if the Auto Gen Start is in Automatic mode.
975-0082-01-013–11
At the time you set for “QT Begin” the generator will
stop (if it is running) and not be able to start again
until the time you set for “QT End”. It ignores all
automatic start triggers during the time period
between “QT Begin” and “QT End”.
Configuration
Use the Quiet Time feature to ensure that the generator will not run during
the night, or to comply with “Quiet Time” guidelines at RV parks and
campgrounds.
To use the Auto Gen Start Quiet Time feature, first set “QT Enable” to
On, then set two times of the day or night (a Quiet Time Begin time and a
Quiet Time End time) to define a time interval during which the generator
will not run.
To disable the Quiet Time feature, set “QT Enable” to Off.
Time zoneWhen travelling between time zones, ensure that you set the clock on the
System Control Panel to your correct local time. Otherwise, your quiet
time settings will come into effect too early or too late.
Battery drainQuiet Time prevents the automatic starting of the generator regardless of
battery condition.
If you need to set a quiet time that lasts overnight, be aware that overnight
battery drain can be significant. Because you may need to use an inverter
and batteries to supply AC power during quiet time, be careful to
conserve battery power. Minimize the use of interior lights and set
thermostat temperature lower to prevent the furnace from coming on at
night during cool weather. Set thermostats higher to prevent air
conditioning coming on at night during warm weather.
OutcomesSometimes automatic start or automatic stop triggers may overlap with
the beginning and end of quiet time. Three different quiet time scenarios
affect when the generator stops and starts.
1. If quiet time begins after the Auto Gen Start has started the generator,
the generator will stop. If the condition that started the generator is
still present when quiet time ends, the generator will restart.
2. If a condition that requires starting the generator occurs during quiet
time, the Auto Gen Start will ignore it until quiet time ends. If the
condition still exists at the end of quiet time (after the time you set for
“QT End”), the Auto Gen Start will start the generator.
3. If the running generator stops when quiet time begins and a condition
that requires stopping the generator occurs during quiet time, the
generator will not restart when quiet time ends.

Start Load
Full nameStart on Inverter Load Current
Purpose“Start Load” is a changeable setting for enabling the generator to start at a
specified AC load on the inverter. The generator will assist the inverter
with powering the AC load.
This setting requires you to set a value for “Stop Load” also.
ValuesDefault
10.0A to 33.0A (increments of 1A)10.0A
When to useYou should change this setting if you have certain “peak” times of power
usage, or have power demands that consistently exceed the output of your
inverter.
If “Enable Load” is set to On, the generator will start in response to the
“Start Load” setting unless the Auto Gen Start is in a Quiet Time period.
Whenever the generator starts automatically in response to inverter load
current, the Auto Gen Start will stop the generator once the load on the
inverter reaches the Stop on Inverter Load Current value.
You can monitor the inverter load current on the System screen.
OutcomesIf you set “Start Load” too high, the Auto Gen Start may not start the
generator in time to recharge the batteries before the batteries are drained
by the AC load. In addition, if “Start Load” is set too high, the inverter
may shut down due to an overload condition.
If you set “Start Load” too low , the Auto Gen St art may start the generator
too frequently, wasting fuel in the process.

When to useSet “Stop Absorb” if you want to deliver a partial charge to your batteries.
The Auto Gen Start will start and run the generator until the inverter/
charger charges the batteries through the Bulk charge stage (restoring the
batteries to about 75% of their full charge). The Auto Gen Start stops the
generator when the inverter/charger determines the batteries have reached
the Absorption charge stage.
Set “Stop Absorb” if your inverter/charger is using two-stage battery
charging. If your inverter/charger is set to use three-stage charging, set
“Stop Float” or “Stop Absorb” to stop the generator.
Set “Stop Absorb” if battery charging is your main priority for your
generator (rather than using your generator for powering high AC loads).
You might also use the “Stop Absorb” setting if your batteries are not
being charged enough before the Auto Gen Start stops the generator
because of battery voltage or state of charge.
975-0082-01-013–25
Configuration
In power systems with long cables between the batteries and the inverter/
charger (over 10 feet [3 m]), the measured battery voltage can be a poor
indicator of battery condition. In such cases, the batteries are more
assured of a full charge if the generator runs until the charger reaches the
Absorb stage, rather than waiting until the charger charges the batteries to
the voltage you may have set for “StopBattV” (see page 3–22).
For more information on battery charging, see your inverter/charger
operation guide.
OutcomesIf you enable the Auto Gen Start to stop the generator at the Absorption
stage, it will stop the generator if it has been started automatically by the
Battery Voltage (“StartV:30sec”, “StartV:15min”, “StartV:2hr”, and
“StartV:24hr”) or State of Charge settings.
If you do not set “Stop Absorb” to On, the Auto Gen Start will not stop
the generator in response to the battery charging stage. The generator will
stop in response to battery voltage (“StopBattV”) instead. In this case,
ensure that the “StopBattV” is enabled and set at the correct voltage.

Operation
Starting and Stopping the Generator
You can use the Auto Gen Start to start the generator manually (on
demand, using the System Control Panel) and automatically (in response
to an electrical system condition).
In general, to avoid Auto Gen Start faults, try not to combine automatic
and external manual starts and stops. When the generator has been started
automatically, let it stop automatically unless you encounter a situation
when the generator must be stopped urgently. Likewise, if you have
started the generator manually, ensure that you stop it manually (only the
“Max Run Time” setting can automatically stop the generator after it has
been started manually).
To set the Auto Gen Start to start and stop the generator
automatically:
1. On the Auto Gen Start menu, highlight AGS Mode and press Enter.
2. Use the up arrow or down arrow button to select Automatic.
3. Press Enter.
The Auto Gen Start will start and stop the generator in response to the
configurable settings you have set for battery voltage, state of charge,
inverter load, quiet time or exercise time. Depending on conditions in
the power system, the generator may start immediately after it is put
in Automatic mode.
To start the generator manually:
1. On the Auto Gen Start menu, highlight AGS Mode and press Enter.
2. Use the up arrow or down arrow button to select ManualOn.
3. Press Enter.
To stop the generator manually:
1. On the Auto Gen Start menu, highlight AGS Mode and press Enter.
2. Use the up arrow or down arrow button to select ManualOff.
3. Press Enter.
4–2975-0082-01-01
Setting Quiet Time
Use the Quiet Time feature to ensure that the Auto Gen S tart will not start
the generator during the night, or during times that might clash with
“Quiet Time” guidelines at RV parks and campgrounds.
Setting Quiet Time for the first time involves three steps:
1. Setting “QT Enable” to On.
2. Setting the “QT Begin” setting.
3. Setting the “QT End” setting.
The default setting for “QT Begin” is 10:00 PM (22:00 if you are using a
24-hour clock) and the default setting for “QT End” is 7:00 AM (7:00 on
the 24-hour clock). If the default settings meet your needs, you only need
to enable or disable Quiet Time when you want to use this feature.
For more information about Quiet Time settings, see “QT Enable” on
page 3–11, “QT Begin” on page 3–11, and “QT End” on page 3–13.

5. Press Exit twice to return to the System screen.
Setting the end of Quiet Time
Setting a time for “QT End” defines the end of Quiet Time. At the time
you set for “QT End”, the Auto Gen Start will be able to start the
generator when an automatic start trigger (such as low battery voltage or a
high inverter load) occurs in the Xanbus system. If there is an automatic
start trigger already active in the system when Quiet Time ends, the
generator will start immediately.
To set the end of Quiet Time:
1. On the Auto Gen Start menu, use the up or down arrow buttons to
highlight “QT End”, then press Enter.
2. Use the up or down arrow button to select the hour, then press Enter.

Changing the system mode
Changing System Modes
Operating mode
CharacteristicsOperating mode is the default mode of the Auto Gen Start. In Operating
mode, the Auto Gen Start communicates on the network, responds to
signal input, and can start and stop the generator automatically. Operating
mode includes all the AGS Modes described on page 3–9 of the
Configuration chapter.
Whenever the Auto Gen Start is powered on, it is in Operating mode (with
the AGS Mode in “ManualOff”).
Power Save mode
CharacteristicsPower Save mode minimizes power draw by the Auto Gen Start and other
devices on the Xanbus system. Power Save mode stops all
communication on the network, putting the system to “sleep” until it
receives a command to “wake up” again. In Power Save mode, the
generator stops, and the Auto Gen Start cannot start it manually or
automatically.
For more information about Power Save mode, see the System Control
Panel Owner’s Guide.
Safe mode
CharacteristicsSelecting Safe mode stops the generator (if it is running) and puts the
Auto Gen Start (and every Xanbus-enabled device in power system) into
Safe mode. While in Safe mode, the Auto Gen Start “listens” to and
reports its status to the network. However, it will not start the generator
manually or automatically while in Safe mode.
When to useBefore changing the “Gen Type” setting (see page 3–16), you must put
the system into Safe mode.
Use Safe mode when adding or removing devices from the network.
Authorized service personnel must also put the system into Safe mode
before performing diagnostics and software upgrades.
If the Auto Gen Start is powered off while in Safe mode, it will be in Safe
mode when it is powered on again.
Important:
cannot put the Auto Gen Start into Safe mode. Before you can enter Safe mode,
you must stop the generator via its external switch and clear the fault.

Once the system is in Hibernate mode, you must restore power to the
network manually.
If an inverter/charger supplies power to the network, you can bring the
system out of Hibernate mode either by pressing the reset button on the
inverter/charger front panel or by applying AC input to the inverter/
charger with utility power or generator power.
