Installation Connecting the Generator CAUTION: Equipment Damage Before connecting the Xantrex XW 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 incorrect Gen Type and following the connection diagram for an incorrect Gen Type when connecting the Xantrex XW AGS to the generator.
Installing the Xantrex XW Automatic Generator Start Generator Types The Xantrex XW AGS has 14 preset generator configurations, or “Gen Types” (see “Gen Type” on page 3–10). After installing the hardware, it will be necessary to select one of these Gen Types from the Xantrex XW AGS Configuration Menu on the Xantrex XW System Control Panel. Important: Put the system in Standby BEFORE changing the “Gen Type”. See “Putting the Xantrex XW AGS in Standby Mode” on page 4–6.
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.

Installing the Xantrex XW Automatic Generator Start Type 2 Type 2 is a three-wire GlowStop configuration recommended for “threewire” generators that don’t require a dedicated preheat signal. In this configuration, the start signal is applied for longer because the generator does its own preheat and cranking while the start signal is applied.
Installation Type 3 Type 3 is a three-wire GlowStop with shutdown bypass configuration. The configuration shown in Figure 2-9 uses a shutdown bypass output to temporarily disable the generator’s low oil pressure shutdown functionality during cranking. Generators with this functionality often have a manual means of disabling it during cranking.
Installing the Xantrex XW Automatic Generator Start Type 4 Type 4 is a three-wire StartStop configuration that uses relay 3 to provide a 60-second preheat signal.
Installation Type 5 Type 5 is a three-wire StartStop configuration that uses relay 3 to provide a 15-second preheat signal.
Installing the Xantrex XW Automatic Generator Start Type 6 Type 6 is a three-wire GlowStop configuration that has a normally closed Run/Stop contact.

Installation Type 7 Type 7 will work with both two-wire and three-wire run mode configurations that require a preheat signal before cranking. This Gen Type setting is suitable for generators with an automatic engine cranking control system (two-wire) and generators that require that the Xantrex XW AGS control their starter separately (three-wire).
Installing the Xantrex XW Automatic Generator Start Type 8 Type 8 will work with both two-wire and three-wire run mode configurations. Type 8 is identical to Type 7 except that it provides no preheat signal before cranking.

Installing the Xantrex XW Automatic Generator Start Type 12 Type 12 is a three-wire GlowStop configuration recommended for “threewire” generators that don’t require a dedicated preheat signal. In this configuration, the start signal is applied for longer because the generator does its own preheat and cranking while the start signal is applied.
Installation Type 13 Type 13 is a three-wire PulseStop configuration that uses relay 3 to provide the preheat signal. With this generator type, there will be a delay between the generator turning off and the Xantrex XW AGS recognizing that the generator is off.
Installing the Xantrex XW Automatic Generator Start Type 14 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 Xantrex XW 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.

Wires 1 (yellow) and 2 (gray) are intended for thermostat 1 and wires 3 (orange) and 4 (gray) are intended for thermostat 2.
Installing the Xantrex XW Automatic Generator Start Connecting an External Shutdown (optional) The external shutdown input is a 12-volt/24-volt input used to assure that the Xantrex XW 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.
Installation WARNING: Fire and Shock Hazards 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 2-2. 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 Xantrex XW AGS to a 48-volt battery bank.
Installing the Xantrex XW Automatic Generator Start Connecting an External ON/OFF LED Wires 9 (White/Blue) and 11 (Black) on the wiring harness can be connected to an LED or other light to accompany a remote external ON/ OFF switch. This light turns on when the generator run signal is active to visually indicate that the generator is running. Important: With some generators, the generator run signal becomes active during the preheat stage, before the generator is actually running.
Installation Connecting the Wiring Harness to the Xantrex XW AGS After all the external connections have been wired to the wiring harness, the connector on the wiring harness must be plugged into the 20-contact connector on the Xantrex XW AGS.
Installing the Xantrex XW Automatic Generator Start Connecting the Xantrex XW AGS to the Xantrex Xanbus Network CAUTION: Equipment Damage Connect only to other Xantrex Xanbus-enabled devices. Although the cabling and connectors used in this network system are the same as those used for Ethernet, this network is not an Ethernet system. Equipment damage may result from attempting to connect a Xantrex Xanbus-enabled device to an Ethernet system.
Installation • A second network cable • A network terminator (when the Xantrex XW AGS is the last device at one end of the network). Connect one or two network cables as required by the installation configuration. Figure 2-26 Connecting the Xantrex XW System Control Panel Verifying Power Is Available When the Xantrex XW AGS has been installed properly, the Power and Network indicator lights illuminate.

For details on the Configuration menu options, see page 3–7.
The Xantrex XW Automatic Generator Start Menu 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 • Multi-unit Config • Restore Defaults QT En Full name Quiet Time Enable Purpose “QT En” enables or disables the Quiet Time functionality of the Xantrex XW AGS. Quiet time refers to a period of time when the generator should not run.
Configuration 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.
The Xantrex XW Automatic Generator 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 a setting for “QT Begin”. Dependencies “QT End” functions only if the Xantrex XW 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 Xantrex XW System Control Panel is set to the correct local time.
Configuration Gen Type Full name Generator Type Purpose “Gen Type” selects the starting requirements of the generator. The starting requirements determine how the Xantrex XW AGS must be wired to the generator’s starting system. For more information, see “Connecting the Generator” on page 2–8 or Appendix B. Important: “Gen Type” can only be changed after the system is put into Standby. See “Putting the Xantrex XW AGS in Standby Mode” on page 4–6.
The Xantrex XW Automatic Generator Start Menu When to use Use this setting after installing the Xantrex XW AGS hardware. Selecting a suitable “Gen Type” automatically configures the Xantrex XW AGS to work with the ignition system and starting requirements of the generator. Consult the generator manual or contact the generator’s manufacturer for specific generator starting requirements.
Configuration Important: The Auto Gen Start mode must be set to Manual Off before any start trigger parameters are set.
The Xantrex XW Automatic Generator Start Menu Start DCV 30 sec Full Name Starting Battery Voltage—30 seconds Purpose The “Start DCV 30 sec” trigger enables the Xantrex XW AGS to start the generator whenever the battery voltage reaches or drops below a preset voltage for longer than 30 seconds. The Xantrex XW AGS will stop the generator when the stop trigger is provided (“Stop V”, “Stop Absorb”, or “Stop Float”).
Configuration Start DCV 15 min Full Name Starting Battery Voltage—15 minutes Purpose The “Start DCV 15 min” trigger enables the Xantrex XW AGS to start the generator whenever the battery voltage reaches or drops below a preset voltage for longer than 15 minutes. The Xantrex XW AGS will stop the generator when the battery voltage has risen to the “Stop V”, or when the batteries have been recharged to the Absorption or Float stage.
The Xantrex XW Automatic Generator Start Menu Start DCV 2 hr Full name Starting Battery Voltage—2 hours Purpose The “Start DCV 2 hr” trigger enables the Xantrex XW AGS to start the generator whenever the battery voltage reaches or drops below a preset voltage for longer than 2 hours. Dependencies The “Start DCV 2 hr” trigger requires the Xantrex XW 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.
Configuration Start DCV 24 hr Full name Starting Battery Voltage—24 hours Purpose The “Start DCV 24 hr” trigger enables the Xantrex XW AGS to start the generator whenever the battery voltage reaches or drops below a preset voltage for longer than 24 hours. Dependencies The “Start DCV 24 hr” trigger requires the Xantrex XW 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.
The Xantrex XW Automatic Generator Start Menu Stop Float Full name Stop at Float Charge Stage Purpose The “Stop Float” trigger allows the Xantrex XW AGS to stop the generator when the inverter/charger has recharged the batteries to the Float stage. Considerations Values Default Disabled, Enabled Disabled “Stop Float” or “Stop Absorb” would typically be used if the generator was started due to a low-battery voltage setting.
Configuration Stop Absorb Full name Stop at Absorption Charge Stage Purpose The “Stop Absorb” triggers enables the Xantrex XW AGS to stop the generator when the inverter/charger has recharged the batteries to the Absorption stage. Considerations Values Default Disabled, Enabled Enabled Set “Stop Absorb” if it’s desired to only deliver a partial charge to the batteries.
The Xantrex XW Automatic Generator Start Menu Stop V Full name Stopping Battery Voltage Purpose The “Stop V” trigger enables the Xantrex XW 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.
Configuration 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 Xantrex XW AGS will start the generator to help power the item controlled by that thermostat. Values 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.
The Xantrex XW Automatic Generator Start Menu 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 Xantrex XW 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” on page 3–22.
Configuration If “Start Load” is set too high, the Xantrex XW 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 Xantrex XW AGS may start the generator too frequently, wasting fuel in the process.
The Xantrex XW Automatic Generator Start Menu Cfg Gen Menu The Cfg Gen Menu provides the means to customize the following settings if the generator being used doesn’t conform to one of the preset generator types or if an exercise period needs to be scheduled.
Configuration Gen Cool Down Purpose The Gen Cool Down setting allows an interval to be set between a generator stop trigger occurring and the Xantrex XW AGS actually stopping the generator. This setting is used in Xantrex XW system to unload the generator before the Xantrex XW AGS shuts it down. When a stop trigger occurs, the Xantrex XW AGS enters a Generator cool down state where it continues to run the generator for the specified time period.
The Xantrex XW Automatic Generator Start Menu Gen Spin Down Purpose The Gen Spin Down setting allows an interval to be set between a generator stop signal being sent at the end of a Gen Cool Down cycle and the Xantrex XW AGS changing the Generator State to “stopped.” This setting is used in the Xantrex XW System to allow the generator to completely stop, thereby reducing its output voltage to zero and pulling the B+ signal low before the Xantrex XW Inverter/Charger can qualify and transfer the generator.
Configuration Max Run Time 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.
The Xantrex XW Automatic Generator Start Menu Exercise Per 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 Xantrex XW 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 Xantrex XW AGS exercised the generator.
Configuration Exercise Dur 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. Values Default 1min to 250min 30min Important: Ensure that the Exercise Duration is not set for longer than the “Max Run Time” setting.
The Xantrex XW Automatic Generator Start Menu Relay3 Purpose Considerations “Relay3” sets the function of Relay 3 of the Xantrex XW AGS. The function of Relay 3 affects contacts 19 and 20 of the 20-contact connector and external wiring harness. Values Default NotUsed, Preheat, PreheatSDByp, WrmUpCoolDn NotUsed 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.
Configuration 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 Xantrex XW AGS to succesfully start the generator.
The Xantrex XW Automatic Generator Start Menu Crank Retry Time Purpose Considerations “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 a “Gen Type” is selected for the generator.
Configuration Multi-unit Config “Multi-unit Config” provides the means to identify multiple units within the same configuration. Dev Name The “Dev Name”, or Device Name, menu item gives each Xantrex Xanbus-enabled device a unique identifiable name. This makes each device easier to identify when multiple Xantrex Xanbus-enabled devices are connected together. The default Device Name for the Xantrex XW AGS is “Xantrex XW AGS.” See the Xantrex XW Inverter/Charger Operator’s Guide for additional information.
The Xantrex XW Automatic Generator Start Menu AC Out The “AC Out” connection tells the Xantrex XW AGS what load to monitor for AC load triggers. Configuration of this parameter is only necessary for systems with more than one Xantrex XW Inverter/Charger. Generator This generator name is used by the Xantrex XW Inverter/Charger to identify which generator is connected to either of the two AC inputs, AC1 or AC2.
Configuration Automatic Mode To have the Xantrex XW 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 3–8, “QT End” on page 3–9, and “Using Quiet Time” on page 4–4).
The Xantrex XW Automatic Generator Start Menu Manual Off Mode Selecting Manual Off Mode overrides the automatic stop settings and manually stops the generator. Manual Off must be selected to stop the generator when the generator has been started manually. The Xantrex XW AGS will not automatically start the generator again until “Automatic” is selected in the GenMode Menu.

B Generator Auto Start Requirements and Types Appendix B describes the generator requirements and starting types that can be used with the Xantrex XW Automatic Generator Start. For this Topic... See...
Generator Auto Start Requirements and Types Recommended Features In order for the generator to be automatically started by the Xantrex XW 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.
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 Three-Wire Onan 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).
Generator Starting Types Three-Wire Automotive The third generator starting type that is supported by the Xantrex XW 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.

C Relay Timing Appendix C contains information about relay configuration and timing for each major type of Xantrex XW AGS starting mode. This information applies to each of the generator types described from page 2–10 to page 2–23. For this Topic.... See....
Relay Timing RunMode For generators with RunMode starting types (Types 7, 8, and 14): • 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.
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.
StartStop Mode StartStop Mode For generators with StartStop mode starting types (Types 4, 5, 9, 10): • Relay 1 (Stop) and Relay 2 (Start) can be used with a common ground for three-wire configured generators. • If Relay 3 is configured for preheat, the signal only shows up on Relay 3. • The Preheat on Relay 3 will not overlap the Crank Time if ShutDown Bypass is not enabled.
Relay Timing PulseStop Mode For generators with PulseStop mode starting types (Type 13): • Relay 1 (Stop) and Relay 2 (Start) can be used with a common ground for three-wire configured generators. • If Relay 3 is configured for Preheat, the signal only shows up on Relay 3. • The Preheat on Relay 3 will not overlap the Crank Time if ShutDown Bypass is not enabled.
