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).

Type 14 works with two-wire generators that use an integrated engine
control module to perform the necessary relay cycles to start and stop the
generator. This is similar to Type 8 but without the B+ signal requirement.
The AGS closes relay 1 to start the generator and illuminates the Generator
On light to indicate the relay is closed. To stop the generator, relay 1 is
opened and the Generator On light turned off.

ensure the generator’s integrated controller has the ability to monitor,
control and report generator status and faults. With Type 14, no faults are
raised if the generator fails to start or stop or is externally started or
stopped.
Once the generator is stopped, there is a 10-minute delay before the
generator can be re-started using the AGS. This is to allow the generator’s
integrated engine controller to completely and safely shut down the
generator. This delay can be adjusted by changing the Gen Spin down
setting.

The external shutdown input is a 12-volt/24-volt input used to assure that
the AGS 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, or
carbon monoxide detector) that produces an active high 12-volt or 24-volt
output.

Wiring for Connecting an External Shutdown
Wiring Harness
Wire Color
In order for the Xanbus Automatic Generator Start (AGS) to be able to
detect these switches, connect the fused positive of the generator battery to
wire 10 on the harness (the constant 12-volt/24-volt wire). See Figure 23 on
page 32. Ensure all circuits added to the system comply with “Circuit
Limitations” on page 11.
If the generator battery does not have the required voltage, any 12-volt or
24-volt power source meeting the limits on page 11, will suit this purpose.
If an alternate power source is used, its positive terminal must be connected
to wire 10. Its negative must be connected to wire 11.
NOTE: Internally, wire 11 is connected to wire 13, so in this
configuration, the alternative power source negative may already be
connected to the negative terminal on the generator battery.
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 sta rting
and stopping the generator manually. Wire 7 (Start) and wire 8 (Stop)
should each run to their own momentary-contact switch or push-button. The
other contact on both switches (common) should be connected to wire 11 on
the harness.
NOTE: Internally, wire 11 is connected to wire 13 so it may already be
connected to the negative terminal on the generator battery.
FIRE AND ELECTRICAL SHOCK HAZARD
When making connections to a 12-volt or 24-volt power source that
exceeds the class 2 power limitation of 100 VA (e.g., a battery) always
use over-current protection as defined in Table 2. This also applies to
thermostat and external manual ON/OFF connections. Locate the
protection device at the power source in the positive wire.
Do not connect the AGS to a 48-volt battery bank. The AGS is limited to
a 30V open-circuit maximum by its regulatory approval and cannot be
connected to a 48-volt power source.
Failure to follow these instructions can result in death or serious
injury.
30 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Xanbus Automatic Generator Start Installation
The External Manual On and External Manual Of f state s are not af fected by
maximum generator run time (see “Max Run Time” on page 55).
EQUIPMENT DAMAGE
Ta pping 12-volts or 24-volts from a 48-volt battery bank will unevenly
wear out the batteries and shortens the battery bank life.
Failure to follow these instructions can damage the unit and/or
damage other equipment.

The Configuration Menu
The Configuration Menu is where specific start-stop parameters are set.
This menu contains the following settings:
• "QT En"
• "QT Begin"
• "QT End"
• "Gen Type"
• "Cfg Trigger"
• "Cfg Gen"
• "Restore Defaults"
QT En
Full name Quiet Time Enable
Purpose "QT En" enables or disables the Quiet Time functionality of the
AGS. Quiet time refers to a period of time when the generator should not
run.
Dependencies "QT En" requires the AGS to be in Automatic mode.
Setting "QT En" to [Enable] requires that parameters be set for the "QT
Begin" and "QT End".
Value Descri ption
Enabled/Disabled Enables or disables the Quiet Time functionality.
When to use Set "QT En" to [Enabled] when there is a period of time
when it is not desired for the generator to run. The AGS will ignore all
automatic start triggers during the time set in "QT Begin" and "QT
Begin".
When there are no preferences or restrictions for when the generator should
run, set "QT En" to [Disabled]. When [Disabled] is selected, the AGS will
ignore the times set for "QT Begin" and "QT End".
Considerations Quiet Time prevents the automatic starting of the
generator regardless of battery condition.
40 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Configuration of the Xanbus AGS
IMPORTANT:
battery drain can be significant as it may be necessary to use the inverter
and batteries to supply AC Power without the help of a generator.
Therefore, it is important to conserve battery power during this time.
Minimize the use of interior lights and set thermost at temper atu re l ower t o
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.
Sometimes 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 AGS 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 AGS will ignore it until quiet time ends. If the condition still
exists at the end of quiet time, the AGS 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.
If quiet time is set for overnight, be aware that overnight
QT Begin
Full name Quiet Time Begin
Purpose "QT Begin" defines the start of quiet time.
Dependencies "QT Begin" functions only if the AGS is in Automatic
mode. This setting requires "QT En" be set to [Enabled].
Ensure the clock on the Xanbus System Control Panel (SCP) is set to the
correct local time.
Value Description
12:00AM to
11:59PM (12-hour

00:00 to 23:59
(24-hour clock)
At the time set for "QT Begin", the generator
will stop (if it is running) and not be able to start
again until the time set for "QT End". It ignores
all automatic start triggers during the time period
between "QT Begin" and "QT End".
975-0082-01-01 41
Configuration of the Xanbus AGS
QT End
Full name Quiet Time End
Purpose "QT End" is a changeable setting that defines the end of quiet
time.
This setting also requires a setting for "QT Begin".
Dependencies "QT End" functions only if the AGS is in Automatic
mode. This setting requires "QT En" be set to [Enabled] and also requires a
setting for "QT Begin".
Ensure the clock on the Xanbus System Control Panel (SCP) is set to the
correct local time.
Value De s cription
12:00AM to
11:59PM (12-hour
clock)

(24-hour clock)
At the time set for "QT End" the AGS will be
able to automatically start the generator again. If
a start trigger has occurred during quiet time and
is still active, the generator will start immediately
after quiet time ends.
Gen Type
Full name Generator Type
Purpose "Gen Type" selects the starting requirements of the generator.
The starting requirements determine how the AGS must be wired to the

Cfg Trigger
The "Cfg Trigger" menu contains the settings for automatically starting
and stopping the generator. This menu allows the adjustment of the default
settings for battery voltage, thermostat ON/OFF signals, inverter load, and
battery charging stage.
There are three classes of triggers: charger-based, thermostat-based, and
inverter load-based. If the generator is started by a trigger in one class, a
stop condition must also be set in order for the generator to stop. For
example for charger triggers, if the generator is started by the "Start DCV
30 sec" condition, any of the accompanying stop triggers "Stop Float",
"Stop Float" and "Stop V" can be used to stop it.
If at least one start trigger is enabled in two or all three trigger classes, the
first trigger to be true will start the generator. Conversely, the last stop
trigger to be met will stop the generator.
Changing the default settings is advised for experienced users or users who
have consulted service personnel.
IMPORTANT:
any start trigger parameters are set.
The Auto Gen Start mode must be set to Manual Off before

44 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Start DCV 30 sec
Configuration of the Xanbus AGS
Full Name Starting Battery Voltag e—30 seconds
Purpose The "Start DCV 30 sec" trigger enables the AGS to start the
generator whenever the battery voltage reaches or drops below a pre-set
voltage for longer than 30 seconds.
The AGS will stop the generator when the stop trigger is provided
("Stop V", "Stop Absorb", or "Stop Float").
Dependencies The "Start DCV 30 sec" trigger requires the AGS to be
in Automatic mode and needs the "Stop Absorb" or "Stop Float"
trigger be enabled or a parameter to be set for the "Stop V" trigger.
Value s De fau lt
Disabled, 4.0 V to 60.0 V (increments of 0.1 V) 11.3 V
Considerations If the voltage trigger is set too high, the generator will
start more frequently than is convenient.
If the voltage trigger is set too low, the batteries may be damaged by
repeated cycles of excessive discharge. The generator running time
necessary to charge the batteries may exceed "Max Run Time" and use too
much fuel in the process.
If using the Xanbus Low Batt Cut Out voltage setting to trigger a start-onvoltage setting on the AGS, be sure to set the AGS voltage trigger higher
than the Xanbus Low Batt Cut out voltage. Otherwise the inverter output
turns off and then back on when the generator auto-starts.
If using an automatic generator starting system with the star t trigger set to
the same voltage as the LBCO voltage, do not set the LBCO Delay for less
than the amount of time it takes the generator to start and connect.
Otherwise, inverter output turns off and then back on when the generator
auto-starts.
Battery Voltage Information Battery voltage can be monitored from the
System screen or the inverter/charger menu.
If "Stop Float" or "Stop Absorb" has been enabled, the generator will
stop when the Float or Absorption stages of the battery charging have
begun.
If the "Stop V" is used, the generator will stop when the battery voltage
reaches the parameter set in this trigger, regardless of whether the batteries
are charged.
975-0082-01-01 45

975-0082-01-01 47
Configuration of the Xanbus AGS
Stop Float
Full name Stop at Float Charge Stage
Purpose The "Stop Float" trigger allows the AGS to stop the
generator when the inverter/charger has recharged the batteries to the Float
stage.
Value s Default
Disabled, Enabled Enabled
Considerations "Stop Float" or "Stop Absorb" would typically be
used if the generator was started due to a low-battery voltage setting.
"Stop Float" is the recommended setting if it is desired that the generator
charge the batteries completely. This will result in somewhat longer run
times. However, if the generator is the primary charging source, charging
them to the Float stage every time will provide longer battery life.
For more information on battery charging, see the Freedom SW Inverter/
Charger Owner’s Guide.
Stop Absorb
Full name Stop at Absorption Charge Stage
Purpose The "Stop Absorb" triggers enables the AGS to stop the
generator when the inverter/charger has recharged the batteries to the
Absorption stage.
Values De fault
Disabled, Enabled Disabled
Considerations Set "Stop Absorb" if it’s desired to only deliver a
partial charge to the batteries. The AGS will start and run the generator until
the inverter/charger charges the batteries through the Bulk charge stage
(restoring the batteries between roughly 75% and 90% of their full charge).
The AGS stops the generator when the inverter/charger determines the
batteries have reached the Absorption charge stage.
Because Stop Absorption will shut down the generator before the batteries
are fully charged, it is recommended to use it only if there is an alternate
charging source, such as wind or PV, which can complete the charge. If the
generator is the only charging source, Stop Absorption will le ave the
batteries consistently undercharged and may shorten the battery life.
Alternately, S top Absorption can be useful dur ing utility outages, when it is
desired to keep the generator run time to a minimum, but are expecting a
full recharge once the power is restored.
For more information on battery charging, see Freedom SW Inverter/
Charger Owner’s Guide.
48 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Stop V
Configuration of the Xanbus AGS
Full name Stopping Battery Voltage
Purpose The "Stop V" trigger enables the AGS to stop the generator
whenever the battery voltage reaches a pre-set DC voltage. Whenever the
generator starts automatically based on the Starting Battery Voltage, it will
shut off once the Stopping Battery Voltage has been reached.
Dependencies The "Stop V" trigger requires the AGS to be in
Automatic mode and needs a parameter to be set for one of the Start DCV
triggers.
Value s Default
Disabled, 14.0 V to 60.0 V
(increments of 0.1 V)
Considerations The "Stop V" setting is most useful when you want the
inverter/charger to give the batteries a quick, basic charge. If using this
mode, it is recommended to run a complete charge or equalize cycle once in
a while to restore the battery. To give the batteries a more complete,
consistent charge, use the "Stop Float" setting. This will result in longer
generator run times.
If "Stop V" is set too high, the generator may run for too long.
If "Stop V" is set too low, the AGS will stop the generator before the
inverter/charger has charged the batteries.
If "Stop Float" or "Stop Absorb" have been enabled, the AGS will
stop the generator if the Float or Absorption stages of the battery charging
have begun.
Disabled
Actual battery voltage can be monitored from the Freedom SW System
Home screen on the Xanbus System Control Panel (SCP).
For more information on battery charging, see the Freedom SW Inverter/
Charger Owner’s Guide.
975-0082-01-01 49
Configuration of the Xanbus AGS
Temp1
Full name Thermostat 1
Purpose The "Temp1" trigger enables the generator to start in response to
a signal from a thermostat. With "Temp1" set to [Enabled], the AGS will
start the generator to help power the item controlled by that thermostat.
Value s Default
Disabled, Enabled Disabled
When to use Enable "Temp1" if a thermostat is available that controls a
component that has a high-power requirement such as a furnace or an air
conditioning system.
Considerations If "Temp1" is enabled, the generator will start in
response to a signal from the thermostat. Everything related to setting the
thermostat must be done on the thermostat. For example: setting the
temperature at which the furnace or air conditioning system comes on must
be done on the thermostat. There are no thermostat temperature settings on
the AGS or the Xanbus System Control Panel (SCP).
If "Temp1" is disabled, the component connected to that thermostat will
require that the generator be started manually in order for that component to
have power. Otherwise, the component will need to be co nnected to another
AC input source.
Temp2
Full name Thermostat 2
Purpose "Temp2" is intended to be used when the AGS is connected to a
second thermostat. All information and procedures for "Temp1" also apply
for "Temp2".
Values Default

Configuration of the Xanbus AGS
Start Load
Full name Enable Inverter Load Start and Stop Triggers
Purpose The "Load" trigger enables or disables the Start on Inverter
Load Current and Stop on Inverter Load Current functionality of the AGS.
This function enables the generator to start and stop based on the current
being drawn on the inverter by the loads. See "Start Load" and "Stop

This function is intended to protect the batteries from rapid
Full name Start on Inverter Load Current
Purpose The "Start Load" trigger enables the generator to start at a
specified AC load (current draw) on the inverter. This current draw must be
present for 5 minutes before the generator will start. The generator will
assist the inverter with powering the AC load.
Dependencies The "Start Load" trigger requires the AGS to be in
Automatic mode and the "Load" trigger to be set to ON. It also needs to
have a stopping value set in the "Stop Load" trigger.
Values Default
10.0 A to 33.0 A (increments of 1A) 10.0 A
Considerations Change this setting if there are certain “peak” times of
power usage or if power demands consistently exceed the output of the
inverter.
If "Load" is set to [Enabled], the generator will start in response to the
"Start Load" setting unless the AGS is in a Quiet Time period.
The inverter load current can be monitored on the System screen.
If "Start Load" is set too high, the AGS 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 "Start Load" is set too low, the AGS may start the generator too
frequently, wasting fuel in the process.
975-0082-01-01 51
Configuration of the Xanbus AGS
Stop Load
Full name Stop on Inverter Load Current
Purpose The "Stop Load" trigger enables the AGS to stop the generator
when the AC load falls below a specific level for 1 minute. The "Stop
Load" setting applies to situations when the AGS has started the generator
to assist the inverter with powering the AC load.
Dependencies The "Stop Load" trigger requires the AGS to be in
Automatic mode and the "Load" trigger to be set to [Enabled]. It also needs
to have a value starting value set in the "Start Load" trigger.

generator before the AGS shuts it down. When a stop trigger occurs, the
AGS enters a Generator cool down state where it continues to run the
generator for the specified time period. At the same time the Freedom SW
Series Inverter/Charger will disconnect the generator when it detects the
AGS in Generator Cool Down, allowing the generator operate unloaded and
cool down before it is shut down.
This helps improves reliability of the generator by reducing temperature
peaking due to abrupt shut down of a loaded generator. It also reduces the
probability of the generator backfiring that typically happens when the
generator is abruptly shutdown while under heavy load. Gen Cool Down
applies to all stop triggers namely Stop V, Stop Load, Stop Float, Stop
Absorb, Stop Load, and Manual Off.
Value s Default
1s to 90s (increments of 1s) 30s
When to use This setting is automatically configured when a “Gen T ype”
is selected for the generator. Customize the “Gen Cool Down” trigger on
the advice of the generator manufacturer or authorized service personnel.
Gen Spin Down
Purpose The Gen Spin Down setting allows an interval to be set betwee n
a generator stop signal being sent at the end of a Gen Cool Down cycle and
the AGS changing the Generator State to “stopped.” This setting is used in
the Freedom SW System to allow the generator to comple tely stop , th ereby
reducing its output voltage to zero and pulling the B+ signal low before the
Freedom SW Series Inverter/Charger can qualify and transfer AC power.
This helps the system operate properly in cases where the generator does
not immediately stop when the stop signal is sent to the AGS. Gen Spin
Down applies to all stop triggers—Stop V, Stop Load, Stop Float, Stop
Absorb, Stop Load, and Manual Off.
Values Default
1s to 900s (increments of 1s) 3s
When to use This setting is automatically configured when a “Gen T ype”
is selected for the generator . Customize the “ Gen Spin Down” trigge r on the
advice of the generator manufacturer or authorized service personnel.
54 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Max Run Time
Configuration of the Xanbus AGS
Exercise Per
Full name Maximum Generator Run Time
Purpose "Max Run Time" allows a limit to be set on how long the
generator will run. This setting overrides any automatic start triggers. For
example, if the generator starts in response to low battery voltage, and the
batteries are not fully charged before "Max Run Time" is reached, the
generator will stop. In addition, when the generator is started manually
from the Xanbus System Control Panel (SCP), the generator will stop when
"Max Run Time" is reached.
When started with an external manual ON/OFF switch, the generator will
not stop when it reaches "Max Run Time". The generator must be stopped
with the external manual ON/OFF switch, or by using the System Control
Panel to change the "GenMode" to ManualOff.
If the AGS reaches "Max Run Time", a warning message will appear on
the Xanbus System Control Panel (SCP). The AGS will stop operating until
the warning is acknowledged by pressing ENTER on the Xanbus System
Control Panel (SCP).
Value s Default
0 hours to 24 hours (increments of 1hour) 8 hours
Considerations Adjust the "Max Run Time" if the maximum generator
run time:
• exceeds the fuel capacity of the generator, or
• is not long enough to fully recharge the batteries under optimum
conditions.
Full name Set Exercise Period (in days).
Purpose "Exercise Per" sets the minimum time interval between each
running of the generator. If the generator has not been run within this time
frame, the AGS will start the generator to “exercise” it.
The time interval defined by the Exercise Period setting begins with th e last
time the generator was run for any reason, not with the last time the AGS
exercised the generator.
For example, setting an exercise period of 30 days would start the generator
if it had not been run at all for 30 days.
Dependencies The "Exercise Per" trigger requires parameters to be
set in the "Exercise Dur" and "Exercise Time" menu items.
Values Default
0 (Off), 1day to 250days (increments of 1day) 21days
Considerations Generators need to run regularly in order to maintain
mechanical health and performance. If the generator isn’t needed and
doesn’t run, it is recommended that an Exercise period be set to keep the
generator in good working condition.
If the generator runs frequently throughout the year, it may not need to be
exercised. In that case, set the "Exercise Per" trigger to 0.
IMPORTANT:
from the generator’s manufacturer for the recommended exerci se period.
Consult the generator manual or a service representative
975-0082-01-01 55
Configuration of the Xanbus AGS
Exercise Dur
Exercise Time
Full name Exercise Duration (in minutes)
Purpose "Exercise Dur" sets how long the generator will run when it
is exercised.
Dependencies The "Exercise Dur" trigger requires that any parameter
other than “0” be set in "Exercise Per" and a time of day be set in the
"Exercise Time" trigger.
Value s Default
1min to 250min 30min
IMPORTANT:
the "Max Run Time" setting. Attempting to do so will generate a warning
on the System Control Panel.
IMPORTANT:
from the generator’s manufacturer for the recommended exercise duration.
Ensure that the Exercise Duration is not set for longer than
Consult the generator manual or a service representative
Purpose "Exercise Time" sets the time of day that the AGS exercises
the generator.
The "Exercise Time" trigger requires that any parameter other than “0”
be set in "Exercise Per" and a value be set in the "Exercise Dur"
trigger.
Values Default
12:00AM to 11:50PM (12-hour clock)
00:00 to 23:50 (24-hour clock)
(increments of 10 minutes)
Considerations If the Exercise Tim e is set, the genera tor will star t a t that
time after being inactive for the Exercise Period.
If the Exercise Time occurs during Quiet Time, the generator will start
when Quiet Time is over and run for the full amount of time set for
"Exercise Dur".
9:00AM
56 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Relay3
Purpose "Relay3" sets the function of Relay 3 of the AGS. The function
of Relay 3 affects contacts 19 and 20 of the 20-contact connector and
external wiring harness.
Value s Default
NotUsed, Preheat, PreheatSDByp NotUsed
Considerations Selecting a value for "Gen Type" automatically
configures "Relay3".
It might be necessary to manually set "Relay3" according to the make and
type of generator being used.
Some diesel generators require preheating of their glow plugs before start
cranking. Setting "Relay3" to Preheat enables Relay 3 to perform this
function in addition to Relay 1.
Some generators require Relay 3 to switch 12 volts to the glow plugs, while
some generators require ground to be switched to the glow plugs.
“PreheatSDByp” stands for Preheat with Shutdown Bypass. Some
generators require preheat on relay 3 to remain high for crank time and
shutdown bypass period. See “GlowStop Mode” on page 84 for more
details.
Configuration of the Xanbus AGS
Gen Run Hold Time
Full name Generator Run Signal Hold Time
Purpose "Gen Run Hold Time" specifies the length of time the
generator run signal (or B+ or hour meter signal) must be active before the
AGS considers the generator to be running and cranking can be stopped.
Some generators assert their run signal when they are being cranked, but
before they have started. They also have varying delays from when
cranking begins or ends to when the run signal is asserted or unasserted.
The Run Hold Time is designed to accommodate these generators.
Values Default
0.0s to 20.0s (increments of 0.5s) 0.5s
Considerations This setting is automatically configured when a "Gen
Type" is selected for the generator. Manually change this setting only on
the advice of the generator manufacturer or authorized service personnel.
If the installation is made without a B+ connection, it might be necessary to
adjust the Gen Run Hold Time for the AGS to successfully start the
generator. When the B+ signal is not connected, the AGS requests generator
status from the Inverter/Charger, which might take longer that if the B+
signal was connected.
975-0082-01-01 57
Configuration of the Xanbus AGS
Crank Delay
Purpose "Crank Delay" specifies the delay time from when the preheat
relay is de-energized to when the S tart Relay is ener gized (and cranking the
starter motor). This is also referred to as the preheat-to-crank delay.
Value s Default
0s to 250s 1s
Considerations This setting is automatically configured when a "Gen
Type" is selected for the generator. Manually change this setting only on
the advice of the generator manufacturer or authorized service personnel.
Crank Time
Purpose "Crank Time" specifies the maximum length of time the Start
relay is engaged (and cranking the starter motor) for the first atte mpt to start
the generator.
Value s Default
0s to 250s (increments of 1s) 30s
Considerations This setting is automatically configured when a "Gen
Type" is selected for the generator. Manually change this setting only on
the advice of the generator manufacturer or authorized service personnel.
Crank Retry Time
Purpose "Crank Retry Time" specifies the length of time the Start
relay is engaged (and cranking the starter motor) for the second and
subsequent attempts to start the generator, in cases when the generator fails
to start on the first attempt.
Values Default
0s to 250s (increments of 1s) 40s
Considerations This setting is automatically configured when a "Gen
Type" is selected for the generator. Manually change this setting only on
the advice of the generator manufacturer or authorized service personnel.
Preheat Time
Purpose "Preheat Time" specifies how long the Preheat relay is
engaged during the start sequence. The preheat signal may be required for
diesel generators with glow plugs or fuel priming for gas generators.
The Preheat relay may be Relay 1 or Relay 3, depending on the "Relay3"
setting or the Gen Type selected.
Values Default
0s to 250s (increments of 1s) 0s
Considerations This setting is automatically configured when a "Gen
Type" is selected for the generator. Manually change this setting only on
the advice of the generator manufacturer or authorized service personnel.
58 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Gen Start Tries
"Gen Start Tries" specifies how many times the AGS will attempt to
start the generator . On the fi rst start try, the AGS cra nks the starter motor
for the Crank Time. If the generator does not start, on subsequent start tries,
the AGS cranks the start motor for the Crank Retry Time.
Value s Default
1 to 10 3
Considerations This setting is automatically configured when a "Gen
Type" is selected for the generator. Manually change this setting only on
the advice of the generator manufacturer or authorized service personnel.

Considerations Use GenMode when it is necessary to switch between
automatic generator control and manual generator control.
When the Xanbus system powers up all network-enabled devices, the AGS
is in ManualOff mode. To enable automatic generator starts, the AGS must
be put in “Automatic” mode.
Automatic Mode
To have the AGS start and stop the generator automatically, select
Automatic. The generator can start and stop automatically in response to
low battery voltage, 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 41, “QT End” on page 42, and
“Using Quiet Time” on page 66).
60 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Automatic Mode Overrides When the AGS is in Automatic mode,
several settings and conditions override automatic start and stop triggers.
These overrides include, in order of priority:
• Faults—The AGS stops the generator when a fault occurs.
• External Shutdown—When the AGS is connected to a sensor or meter
(a moisture detector, for example) wired to contacts 5 and 6 of the 20contact connector, it stops the generator when the device is activated.
See “Connecting an External Shutdown (optional)” on page 30.
• External On/Off—The generator is manually started or stopped with a
switch wired to contacts 7 and 8 of the 20-contact connec tor. See
“Connecting an External Manual ON/OFF Switch (optional)” on page
30. When started with an external manual ON/OFF switch, the
generator will not stop when it reaches Max Run Time. The generator
must be stopped 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 Xanbus System Control
Panel (SCP). The AGS will stop operating until the warning is
acknowledged by pressing Enter on the Xanbus System Control Panel
(SCP). See “Max Run Time” on page 55.
• Manual On—The generator is started by selecting Manual On mode.
• Manual Off—The generator is stopped by selecting Manual Off mode.

Modes of Operation
Operation of the Xanbus AGS
Putting the AGS in Standby Mode
The AGS, like all other Xanbus-enabled devices, supports two modes,
Operating and Standby . The AGS mode of operation must be set to S tandby
before selecting a Generator T ype. Selecting S tandby stops the generator (if
it is running).
While in Standby, the AGS “listens” to and reports its status to the network.
However, it will not start the generator manually or automatically while in
Standby.
If the AGS is powered off while in Standby, it will be in Standby when it is
powered on again.
The AGS can also be put in Standby using the system mode option under
system settings. However, note that selecting Standby from system settings
affects the behavior of the entire Freedom SW system. System mode
Standby puts every Xanbus-enabled device in Freedom SW Power System
into Standby.
IMPORTANT:
If AGS Fault 201 “Unable to stop gen.” is active, the AGS
cannot be put into Standby. Before Standby can be established, the
generator must be stopped by its external switch and the fault must be
cleared.
Use the Xanbus System Control Panel (SCP) to put the AGS into Standby
mode.

Troubleshooting
Under certain conditions, the AGS generates a fault or warning message.
These messages appear on the Xanbus System Control Panel (SCP).
Acknowledging messages When a fault or warning message appears, it
will remain on the screen until it is acknowledged by pressing Enter on the
Xanbus System Control Panel (SCP). This action removes the message
from the screen, but does not clear the condition that caused the fault or
warning.
Consult Table 6 and Table 7 for recommendations for resolving the fault
after it has been acknowledged.
W arnings that are in the form of a Yes/No question can be acknowledged by
pressing Enter for Yes and Exit for No.
Self-clearing warnings If unacknowledged, some warnings may clear
themselves if the condition that generated the message goes away. For
example, if the AGS fails to start the generator, warning message W202
appears. However, if the generator starts on the next start try, the message
goes away.
Clearing faults To clear active AGS faults, highlight Clear Faults on the
AGS menu and press Enter.
Multiple faults and warnings If several fault or warning messages occur
before they can be acknowledged or cleared, they are displayed together on
a fault list or a warning list. These lists contain messages from every
Xanbus-enabled device, not just the AGS. Message details can be selected
and viewed from the fault list or warning list.
To view a message from a fault list or warning list:
1. On the list, use the arrow buttons to highlight the message to be
viewed.
2. Press Enter.
The complete message appears.
To return to the fault list or warning list, press Exit.
To continue to the menu for the device that caused the fault or warning
condition by pressing Exit.
Each time you return to the list after viewing a complete message, the
viewed message is removed from the list.
If you have left the fault list or warning list, you can view them at any time

78 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Appendix A: Generator Auto Start Requirements and Types
Recommended Features
In order for the generator to be automatically started by the AGS, it must
include electric start and an automatic choke. An automatic primer system
may also be required on natural gas and propane powered generators. The
generator should also include remote start ability with accessible remote
start terminals or a connector. Protective systems for low oil pressure, over
temperature, starter lockout and over crank control are valuable features
that will prevent generator damage and increase system reliability. “Twowire” start generators are highly recommended because of the greater
simplicity for automatic starting and because they are intended for remote/
automatic/unattended operation.
Generator Starting Types
The AGS supports three major generator starting types:
• Two wire
• Three-wire “Onan”
• Three-wire automotive
NOTE:
The terms “two-wire” and “three-wire” refer only to the minimum
number of wires necessary to start the ge nerator. Actual installations will
require additional wires to connect to the generator, including the generator
run signal (switched B+) wiring, and wiring to an optional external ON/OFF
switch. For installation wiring diagrams, see page 15 to page 28.
NOTE: For overcurrent protection guidelines that apply to the wiring types
discussed in this appendix, see page 11.
975-0082-01-01 79
Appendix A: Generator Auto Start Requirements and Types
Two Wire
Three-Wire Onan
The two-wire type is suitable for generators that are fully automatic. This
merely requires two wires to be connected together for the generator to sta rt
and run. Separating the wires stops the generator.
Some generators use a momentary two-wire connection for starting and
stopping.
Identification
Generators of this type are usually operated with a simple toggle switch or
key that turns to on, then off to shut the generator off.
Connection
For this type of generator, the two wires are connected to the normally open
and common contacts of Relay 1 (wires 14 and 16). When the AGS receives
a command to start the generator, it cl oses the contacts inside Relay 1,
allowing the generator to start. The contacts remain closed for the duration
of the generator run and open when the AGS needs the generator to stop.
The three-wire “Onan” starting type is suitable for generators that are not as
automated as the two-wire type. It requires a minimum of three wires: a
common wire, a start wire and a stop wire. You may also need to connect
the glow plug wires to Relay 1 (wire 14) or Relay 3 (wire 19). If the
generator requires independent control of the glow plugs, power may also
need to be run to Relay 3 (wire 20).
Identification
Generators of this type are controlled with a three-position switch that is
normally in a center (or neutral) position. To start the generator, the switch
is pressed and held to the start position until the generator starts. The swit ch
is then released, and it returns to the center position. To stop the generator,
the switch is pressed and held to the stop position until the generator stops.
Again, releasing the switch returns it to the center position.
Connection
The common wire from the generator should connect to the common
connections of both Relay 1 and Relay 2 (wires 16 and 18 respectively).
The start wire from the generator connects to the normally open contact of
Relay 2 and the generator stop wire connects to the normally open contact
of Relay 1.
80 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Three-Wire Automotive
The third generator starting type that is supported by the AGS is similar to
an automotive-style ignition. In this style, the generator uses a run circuit
that is normally closed, which then receives a momentary start signal. The
run circuit remains active throughout the run and then is opened in order for
the generator to stop.
Identification
Generators of this type are controlled by a key or rotary switch that acts
exactly as an automotive ignition. The switch is first turned to an “on” (or
run) position, then further to a start position. After starting, the switch
returns to the “on” (or run) position. Other variations are a toggle switch
that gets turned on with a separate switch or push button for start. If glow
plugs are used, you would turn the key or rotary switch to the left prior to
starting. A separate momentary switch or button may be used for this
purpose.
Connection
This generator starting type uses the most wires. The common wire from
the generator should connect to the common connections of both Relay 1
and Relay 2 (wires 16 and 18 respectively). Y ou may need an additional two
wires if glow plugs are used. The start wire from the generator connects to
the normally open contact of Relay 2 and the generator stop wire connects
to the normally open contact of Relay 1.

• The Preheat signal shows up on Relay 1 and also Relay 3 (if enabled)
so that Relay 1 can be used for both Preheat and Stop.
• If the ShutDown Bypass is enabled, the Preheat on Relay 1 will remain
high for the Crank Time and for the ShutDown Bypass period after
cranking.

time set to zero.
• The AGS will make three attempts to stop the generator. If the
generator has still not stopped at the end of the third attempt, the
appropriate Fault will be generated.
• Each stop attempt will consist of engaging the stop relay for 5 seconds
and then waiting 20 seconds before checking the state of the Gen Run
Signal to see if the stop attempt was successful.
