Introduction
IMPORTANT: The Xanbus Automatic Generator Start (AGS) is designed
for use in a Xanbus-enabled Freedom SW Power System only.
The Xanbus AGS requires the additional use of a Xanbus System Control
Panel (SCP) for configuration and monitoring. For details see "System
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.

Introduction
System Requirements
Minimum basic system components include the following:
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)
Xanbus Automatic Generator Start (AGS)
Xanbus System Control Panel (SCP) A Xanbus System Control Panel
(SCP) is required to configure the AGS and monitor generator starting and
stopping activity.
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.
The Xanbus System Control Panel (SCP) also provides real-time clock
information for the AGS Quiet Time and Exercise Time features.
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.

The following section describes the preset generator configurations and
provides diagrams for connecting the wiring harness to the generator’s start
wiring.
Failure to follow these instructions can damage the unit and/or

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.
IMPORTANT: Connecting the B+ Gen Run signal is optional. It the
B+ Gen Run signal is not connected, it may be necessary to adjust the
Gen Run Signal hold time parameter on the AGS. See “Gen Run Hold

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

indicate the generator is actually running. If this generator type is used,
ensure the generator’s integrated controller has the ability to monitor,

Xanbus Automatic Generator Start Installation
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.
Connecting an External Shutdown (optional)
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.
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.
Table 2 Wiring for Connecting an External Shutdown
Wire
Number

NOTE: Internally, wire 11 is connected to wire 13, so in this

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
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.
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. 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.
Failure to follow these instructions can result in death or serious
injury.
NOTE: Internally, wire 11 is connected to wire 13 so it may already be
connected to the negative terminal on the generator battery.

The External Manual On and External Manual Off states are not affected by
maximum generator run time (see “Max Run Time” on page 55).
EQUIPMENT DAMAGE
Connecting an External ON/OFF LED
Tapping 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.
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.
Table 3 Wiring for Connecting an External Manual ON/OFF
Switch
IMPORTANT: With some generators, the generator run signal becomes
active 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
AGS) will turn on during the preheat stage and remain on when the
generator is running.

Configuration of the Xanbus AGS
QT Begin
IMPORTANT: If quiet time is set for overnight, be aware that overnight
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 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.
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.
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.
Value
Description
12:00AM to
11:59PM (12-hour
clock)
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".
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.

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.
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.
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 leave the
batteries consistently undercharged and may shorten the battery life.
Alternately, Stop Absorption can be useful during 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.

Stop V
Full name Stopping Battery Voltage
Actual battery voltage can be monitored from the Freedom SW System
Home screen on the Xanbus System Control Panel (SCP).
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.
For more information on battery charging, see the Freedom SW Inverter/
Charger Owner’s Guide.
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.
Values
Default
Disabled, 14.0 V to 60.0 V Disabled
(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.

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 connected to another
AC input source.

Load
Start Load
Full name Enable Inverter Load Start and Stop Triggers
Full name Start on Inverter Load Current
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
Load".
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.
Dependencies The "Load"trigger requires the AGS to be in Automatic
mode and needs parameters to be set for both the "Start Load"and
"Stop Load"triggers.
Values

Considerations Change this setting if there are certain “peak” times of
power usage or if power demands consistently exceed the output of the
inverter.
IMPORTANT: This function is intended to protect the batteries from rapid
drain. It is not intended to protect the inverter against overload.
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.

Purpose The Gen Cool Down setting allows an interval to be set between Purpose The Gen Spin Down setting allows an interval to be set between
a generator stop trigger occurring and the AGS actually stopping the
generator. This setting is used in Freedom SW system to unload the
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.
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 completely stop, thereby
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.
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.

Configuration of the Xanbus AGS
Max Run Time
Exercise Per
Full name Maximum Generator Run Time
Full name Set Exercise Period (in days).
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.
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 the 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.
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.
Dependencies The "Exercise Per"trigger requires parameters to be
set in the "Exercise Dur"and "Exercise Time"menu items.
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).
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.
Values
Default
0 hours to 24 hours (increments of 1hour)
8 hours
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.
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.
IMPORTANT: Consult the generator manual or a service representative

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.
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

Considerations If the Exercise Time is set, the generator will start at that
time after being inactive for the Exercise Period.
IMPORTANT: Ensure that the Exercise Duration is not set for longer than
the "Max Run Time"setting. Attempting to do so will generate a warning
on the System Control Panel.
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".

Gen Run Hold Time
Relay3
Full name Generator Run Signal Hold Time
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.
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.

0.0s to 20.0s (increments of 0.5s)
0.5s
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.
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.
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.
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.
“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.

Operation of the Xanbus AGS
Putting the AGS in Standby Mode
Modes of Operation
Use the Xanbus System Control Panel (SCP) to put the AGS into 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 Standby
before selecting a Generator Type. Selecting Standby stops the generator (if
it is running).
To put the AGS in Standby Mode:
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.

Troubleshooting
Under certain conditions, the AGS generates a fault or warning message.
These messages appear on the Xanbus System Control Panel (SCP).
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.
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.
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.
Consult Table 6 and Table 7 for recommendations for resolving the fault
after it has been acknowledged.
Each time you return to the list after viewing a complete message, the
viewed message is removed from the list.
Warnings that are in the form of a Yes/No question can be acknowledged by
pressing Enter for Yes and Exit for No.
If you have left the fault list or warning list, you can view them at any time
from the System Settings menu.
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.
To view a fault list or warning list:
1. On the Select Device menu, highlight System and press Enter.
2. On the System Settings menu, highlight View Fault List or View
Warning List.
Clearing faults To clear active AGS faults, highlight Clear Faults on the
AGS menu and press Enter.
3. 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.

Appendix A: Generator Auto Start Requirements and Types
Recommended Features
Generator Starting Types
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. “Two-
wire” start generators are highly recommended because of the greater
simplicity for automatic starting and because they are intended for remote/
automatic/unattended operation.
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 generator. 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.

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 start
and run. Separating the wires stops the generator.
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).
Some generators use a momentary two-wire connection for starting and
stopping.
Identification
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.
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 switch
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
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 closes 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.
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.

Appendix A: Generator Auto Start Requirements and Types
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). You 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.

Appendix B: Relay Timing
RunMode
For generators with RunMode starting types (Types 7, 8, and 14):
•
•
•
The Preheat will never overlap the Crank Time.
The “Delay” refers to the “Preheat to Crank Delay” and may be zero.
Cranking will cease when the generator run signal goes high for the
specified hold time or when the crank time has elapsed.
•
•
Relay 1 (RunStop relay) can be used for two-wire configured
generators.
Relay 1 (RunStop) and Relay 2 (Start) can be used with a common
ground for three-wire configured generators.

MomentaryRun Mode
For generators with MomentaryRun mode starting types (Type 11):
•
•
•
•
Preheat will generally not be used in this configuration.
The Preheat will never overlap the Crank Time.
The “Delay” refers to the “Preheat to Crank Delay” and may be zero.
Cranking will cease when the generator run signal goes high for the
specified hold time or when the crank time has elapsed.
•
Relay 1 (Run/Stop relay) can be used for two-wire configured
generators.
•
Relay 2 has no unique function in this configuration, but it is easiest to
leave it doing the cranking so that another configuration is not required
for it.

GlowStop Mode
For generators with GlowStop mode starting types (Types 1, 2, 3, 6, 12):
•
The Preheat on Relay 3 will only overlap the Crank Time and perform
ShutDown Bypass if Relay 3 is configured for Preheat with ShutDown
Bypass.
The “Delay” refers to the “Preheat to Crank Delay” and may be zero.
Cranking will cease when the generator run signal goes high for the
specified hold time or when the crank time has elapsed.
•
•
•
Relay 1 (Stop) and Relay 2 (Start) can be used with a common ground
for three-wire configured generators.
•
•
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.

For generators with PulseStop mode starting types (Type 13):
•
•
•
To get the ShutDown Bypass on Relay 3 with no preheat, Relay 3 must
be configured for Preheat with ShutDown Bypass and have the Preheat
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.
•
Relay 1 (Stop) and Relay 2 (Start) can be used with a common ground
for three-wire configured generators.
