1 Introduction Chapter 1 describes the main features of the Automatic Generator Start. It also describes the Xanbus System of which the Auto Gen Start is a component.
Introduction About the Automatic Generator Start Function and benefits 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.
Features Features Generator starting The Auto Gen Start can automatically start a generator in response to: • • • • • low battery voltage low battery capacity (“state of charge”) high inverter load a thermostat signal a pre-programmed exercise period You can also use the Auto Gen Start to manually start and stop the generator at any time. Generator compatibility The Auto Gen Start supports two and three-wire generator starters.
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. Generator The 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.
Front and Bottom Panel Front and Bottom Panel Indicator lights Four lights on the front panel indicate the operating status and network status of the Auto Gen Start. Connectors Two network ports on the bottom panel connect the Auto Gen Start to the Xanbus system. A 20-contact pluggable connector (also on the bottom panel) allows the Auto Gen Start to connect to the generator’s starting circuitry, thermostats and external switches. See “Bottom panel” on page 1–6.

Installing the Auto Gen Start Connecting the generator To connect the Auto Gen Start to a generator, you must identify the start wiring configuration of the generator you want to use. Generators must be auto-start capable, and generators equipped with remote operation connections are ideal.
Installation Type 1 Type 1 is a three-wire GlowStop configuration recommended for “threewire” generators with glow plugs that need to be operated before a start is attempted. AGS wiring harness Generator wires 12 GEN RUN SIGNAL GROUND 13 Relay 1 Relay 2 14 5A fuse STOP/PREHEAT 5A fuse START 16 17 Complete overcurrent protection not shown. Refer to page 2–6.
Installing the Auto Gen Start Type 2 Type 2 is a three-wire GlowStop configuration recommended for “threewire” generators that don’t require a dedicated preheat signal, such as Onan 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.
Installation Type 3 Type 3 is a three-wire GlowStop with shutdown bypass configuration. The configuration shown in Figure 2-5 uses a shutdown bypass output to temporarily disable the generator’s low oil pressure shutdown functionality during cranking. (Generators with this functionality often have a manual means of disabling it during cranking.
Installing the Auto Gen Start Type 4 Type 4 is a three-wire StartStop configuration that uses relay 3 to provide the preheat signal for Generac’s Guardian Gas generators. AGS wiring harness Generator wires 12 13 GEN RUN SIGNAL GROUND Relay 1 14 16 5A fuse STOP/PREHEAT 17 18 5A fuse Relay 2 START 19 5A fuse FUEL PRIME (PREHEAT) 12V GENERATOR BATTERY + Relay 3 20 Complete overcurrent protection not shown. Refer to page 2–6.
Installation Type 5 Type 5 is a three-wire StartStop configuration that uses relay 3 to provide the preheat signal for Generac’s Guardian Diesel generators. The wiring diagram for a Type 5 configuration is the same as a Type 4 (see Figure 2-6).
Installing the Auto Gen Start Type 6 Type 6 is a three-wire GlowStop configuration that has a normally closed Run/Stop contact. This generator type is intended for Yamaha generators.

Installation Type 11 Type 11 is a two-wire run mode configuration intended for Kohler generators. It requires only two wires and one relay to control the generator. Relay 1 closes momentarily once to start the generator, and closes momentarily again to stop the generator. The wiring diagram for a Type 11 configuration is the same as a two-wire Type 7 configuration. See Figure 2-8.
Installing the Auto Gen Start Type 12 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. The wiring diagram for a Type 12 configuration is the same as a threewire Type 2 configuration. See Figure 2-4.
Installation Type 13 Type 13 is a three-wire PulseStop configuration that uses relay 3 to provide the preheat signal for PowerTech’s Diesel generators. With this generator type, there will be a delay between the generator turning off and the Auto Gen Start recognizing that the generator is off. The wiring diagram for a Type 13 configuration is the same as a Type 4 (see Figure 2-6).
Installing the Auto Gen Start 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.
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.

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.
The Auto Gen Start Menu QT Enable Full name Quiet Time Enable Purpose “QT Enable” enables or disables the Quiet Time functionality of the Auto Gen Start. “QT Enable” applies only when the Auto Gen Start is in Automatic mode. When to use Value Description On, Off Enable or disable the Quiet Time functionality. When 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”.
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.
The Auto Gen Start Menu 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 you to set “QT Begin”. When to use Value Description 12:00AM to 11:59PM (12-hour clock) 00:00 to 23:59 (24-hour clock) At the time you set for “QT End” the Auto Gen Start will be able to automatically start the generator again.
Configuration State of charge information When a DC Monitor is installed, you can monitor the batteries’ state of charge on the System screen or inverter/charger menu. Outcomes If you set “Start SOC” too high, the generator will start more frequently than is convenient. If you set “Start SOC” too low, your batteries may be damaged by repeated cycles of excessive discharge.
The Auto Gen Start Menu Whenever the generator starts automatically in response to “Start DCV”, it will stop when the battery voltage reaches the Stop Battery Voltage (“StopBattV”) setting. If you have enabled “Stop Float” or “Stop Absorb”, the generator will stop when the Absorption or Float stages of the battery charging have begun. Outcomes If you set “Start DCV” too high, the generator will start more frequently than is convenient.
Configuration Enable Temp2 Full name Enable Thermostat 2. Purpose “Enable Temp2” is intended to be used when the Auto Gen Start is connected to a second thermostat. All information and procedures for “Enable Temp1” also apply for “Enable Temp2”. Values Default On, Off Off (disabled) Gen Type Full name Generator type Purpose “Gen Type” is a changeable setting for selecting the starting requirements of your generator.

Selecting a suitable “Gen Type” automatically configures the Auto Gen Start to work with the ignition system and starting requirements of your generator.
Configuration Auto Gen Start advanced menu The Auto Gen Start advanced menu contains settings that can give you even more control over automatic generator starts and stops. To view the Auto Gen Start advanced menu on the System Control Panel, see page 4–5.
The Auto Gen Start Menu AGS Triggers menu The AGS Triggers menu contains additional settings for automatically starting and stopping the generator. This menu allows you to adjust the default settings for state of charge (when a DC Monitor is installed), battery voltage, thermostat on/off signals, inverter load and battery charging stage. Adjusting these settings beyond their default settings is advised for experienced users or users who have consulted service personnel.
Configuration Purpose When to use “Stop SOC” is a changeable setting that allows you to set the Auto Gen Start to stop the generator when the batteries reach a pre-set state of charge. Values Default Off, 50% to 95% (increments of 5%) Off In Automatic mode, the Auto Gen Start will stop the generator when the batteries’ state of charge equals the “Stop SOC” setting.
The Auto Gen Start Menu When to use Values Default Off, 4.0V to 60.0V Off (disabled) In Automatic mode, the Auto Gen Start will start the generator when the system battery voltage (as measured by the inverter/charger) falls below the “StartV:15min” setting for 15 minutes.
Configuration If the Auto Gen Start is set to Automatic mode, then the Auto Gen Start will start the generator when the system battery voltage (as measured by the inverter/charger) falls below the “StartV:2hr” setting for 2 hours. See “StartV:15min” for more information.
The Auto Gen Start Menu Stopping conditions Whenever the generator starts automatically based on the Starting Battery Voltage, it will shut off once the Stopping Battery Voltage has been reached. If “Stop Float” or “Stop Absorb” have been enabled, the Auto Gen Start will stop the generator if the Float or Absorption stages of the battery charging have begun. Actual battery voltage can be monitored from the System screen on the System Control Panel.
Configuration Outcomes Selecting On enables the Start on Inverter Load Current (“Start Load”) and Stop on Inverter Load Current (“Stop Load”) functionality. If the Auto Gen Start is in Automatic mode and “Enable Load” is set to On, the Auto Gen Start stops and starts the generator according to the values you have set for “Start Load” and “Stop Load”. Selecting Off disables the Start on Inverter Load Current and Stop on Inverter Load Current functionality.
The Auto Gen Start Menu Stop Load Full name Stop on Inverter Load Current Purpose “Stop Load” sets the Auto Gen Start to stop the generator at a specified AC load on the inverter. The “Stop Load” setting applies to situations when the Auto Gen Start has started the generator to assist the inverter with powering the AC load. When to use Values Default 7.0A to 28.0A (increments of 1 A) 7.0A Use this setting when you have set a value for “Start Load”.
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).
The Auto Gen Start Menu assured of a full charge if the generator runs until the charger reaches the Float 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 guide.
Configuration Generator Configuration menu The Generator Configuration (AGS Gen Config) menu contains additional options for configuring the Auto Gen Start for your make and model of generator. The items on this menu include the settings you automatically select when you select a Gen Type (see “Gen Type” on page 3–16). This menu also allows you to set the generator exercise period.
The Auto Gen Start Menu Max Run Time Full name Maximum Generator Run Time Purpose The Max Run Time setting allows you to set a limit 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 your batteries are not fully charged before “Max Run Time” is reached, the generator will stop.
Configuration This setting also requires you to set an Exercise Duration (see “Exercise Dur” on page 3–30) and an Exercise Time (see “Exercise Time” on page 3–31). 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 with equipped with an Auto Gen Start otherwise unattended.
The Auto Gen Start Menu Important: Ensure that you do not set Exercise Duration for longer than “Max Run Time”. Attempting to do so will generate a warning on the System Control Panel. Important: Consult your generator manual or a service representative from your generator’s manufacturer for the recommended exercise duration. Exercise Time Purpose “Exercise Time” allows you to set the time of day that the Auto Gen Start exercises the generator.
Configuration 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.
The Auto Gen Start Menu Crank Retry Time Purpose When to use “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 This setting is automatically configured when you select a “Gen Type” for your generator.
Configuration Start Tries “Start Tries” specifies how many times the Auto Gen Start will attempt to start the generator. On the first start try, the Auto Gen Start cranks the starter motor for the Crank Time. If the generator does not start, on subsequent start tries, the Auto Gen Start cranks the start motor for the Crank Retry Time. When to use 3–34 Values Default 1 to 10 3 This setting is automatically configured when you select a “Gen Type” for your generator.
The Auto Gen Start Menu AGS: Device Info menu The Device Info menu allows you to view the Fault, Warning and Event logs. On the Device Info menu you can also restore the default settings for the Auto Gen Start. View Fault Log Purpose The Fault Log displays the last 20 Auto Gen Start faults for your reference.

Setting the end of Quiet Time Setting a time for “QT End” defines the end of Quiet Time.
Viewing the Advanced Menu Viewing the Advanced Menu The System Control Panel can display the Auto Gen Start menu in two formats: basic and advanced. The Auto Gen Start basic menu is displayed by default. It lists status information and settings you may have to adjust routinely. See “The Auto Gen Start basic menu” on page 3–7 for a list of basic menu items and configuration information. The Auto Gen Start advanced menu lists additional settings and submenus.
Operation Changing System Modes The system modes described in this section affect the behavior of the Auto Gen Start and every Xanbus-enabled device in the system. You will have to change the system mode when setting a Generator Type, travelling, putting your vehicle in storage, or when installing a new Xanbus-enabled device. The system modes you can select are: • • • • Operating Power Save Safe Hibernate You can change system modes using the System Settings menu on the System Control Panel.
Changing System Modes Operating mode Characteristics Operating 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”).
Operation Hibernate mode Characteristics Hibernate mode removes power from the Auto Gen Start and all Xanbusenabled devices on the Xanbus system. The Auto Gen Start suspends all operations (including starting and stopping the generator) until power is restored to the network. Important: Put the system into Hibernate mode before putting your RV or boat in storage. This will prevent the Auto Gen Start from starting the generator while unattended.
5 Troubleshooting Chapter 5 contains information and procedures to troubleshoot the Auto Gen Start, including tables of warnings and faults for your reference.
Troubleshooting Faults and Warnings Under certain conditions, the Auto Gen Start generates a fault or warning message. These messages appear on the System Control Panel. This section describes how to respond to fault and warning messages when they appear. Acknowledging messages When a fault or warning message appears, you can acknowledge the message by pressing Enter on the System Control Panel. This action removes the message from the screen.
Warning Messages 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. 3. Press Enter. Warning Messages Table 5-1 provides details and suggests action for Auto Gen Start warnings. Table 5-1 Auto Gen Start warning messages Warning Number Message Selfclearing? Cause Action W200 Generator was stopped manually. No Generator was stopped by an external Manual Off switch.
Troubleshooting Table 5-1 Auto Gen Start warning messages Warning Number Message Selfclearing? Cause Action W204 No Manual Off: Max generator cycles reached. Reset AGS Mode. The generator has reached its maximum number of start-and-stop cycles. To help prevent an unattended generator from starting, the Auto Gen Start changed the AGS Mode to ManualOff. Acknowledge the warning. Return the Auto Gen Start to the desired AGS Mode (Automatic or ManualOn).

B Generator Auto Start Requirements and Types Appendix B describes the generator requirements and starting types that can be used with the Auto Gen Start.
Generator Auto Start Requirements and Types Recommended Features In order for the generator to be automatically started by the Auto Gen Start, 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.
Generator Starting Types Two wire 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. 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.
Generator Auto Start Requirements and Types 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. Three-Wire Automotive The third generator starting type that is supported by the AGS is similar to an automotive-style ignition.
C Relay Timing Appendix C contains information about relay configuration and timing for each major type of Auto Gen Start starting mode. This information applies to each of the generator types described from page 2–10 to page 2–20.
Relay Timing RunMode For generators with RunMode starting types (Types 7 and 8): • • • • • 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. 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.
MomentaryRun Mode MomentaryRun Mode For generators with MomentaryRun mode starting types (Type 11): • • • • • • 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. Preheat will generally not be used in this configuration. The Preheat will never overlap the Crank Time.
Relay Timing GlowStop Mode For generators with GlowStop mode starting types (Types 1, 2, 3, 6, 12): • • • • • • 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.
PulseStop Mode • • • • 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. 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. StartStop mode is essentially the same as GlowStop mode with no preheat on Relay 1.
Relay Timing • • The Auto Gen Start 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.
