The XW Automatic Generator Start

Important: You can only change GenType after you have put the system or the XW Automatic Generator Start into Standby mode. See the XW Inverter/Charger Operation Guide for instructions on putting the system in Standby Mode.

This section describes the generator configurations and provides diagrams for connecting the wiring harness to the generator’s start wiring.

Important: For an explanation of the terminology used in the following section, refer to Appendix B of the XW Automatic Generator Start Owner’s Guide. For more information about XW Automatic Generator Start internal relay activity and timing, see the Automatic Generator Start Owner’s Guide.

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.

Table 5-4Wiring for Connecting Thermostats

		Wiring Harness
Wire Number	Function	Wire Color
1	Thermostat 1 input (12/24 V)	Yellow
2	Thermostat 1 return (ground)	Gray
3	Thermostat 2 input (12/24 V)	Orange
4	Thermostat 2 return (ground)	Gray

These wires connect to 12-volt/24-volt output signals from the thermostats. The XW Automatic Generator Start will start the generator in response to these signals. Thermostats can not be programmed using the XW Automatic Generator Start.

For specific information about thermostat wiring and where XW Automatic Generator Start connections should be made, please consult your thermostat documentation or contact the thermostat manufacturer.

Connecting an External Shutdown (optional)

The external shutdown input is a 12-volt/24-volt input used to assure that the XW Automatic Generator Start keeps the generator off under conditions that may be potentially hazardous. Wire 5 (white/black) and 6 (gray) on the wiring harness are intended for an external switch or sensor (such as a moisture detector, carbon monoxide detector or coach running signal) that produces an active high 12-volt or 24-volt output.

5	External shutdown input (12/24 V)	White/Black
6	External shutdown return (ground)	Gray
