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.

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.

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).

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 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.

Automatic Generator specifications

Xantrex Technology has established a reputation for excellence in the power management sector, and its Automatic Generator Start (AGS) system is a prime example of this commitment to innovation. This advanced technology is designed for use in recreational vehicles (RVs), marine applications, and remote cabins, providing a reliable solution for maintaining power during off-grid conditions.

One of the main features of the Xantrex AGS is its ability to automatically start and stop generator engines based on specific parameters set by the user. This ensures that power is available when needed, while also preserving fuel and extending the life of the generator itself. The AGS monitors the battery voltage closely, activating the generator if it drops below a predetermined threshold. Once the battery is adequately charged, the system will automatically shut the generator off, preventing unnecessary fuel consumption and wear on the engine.

The Xantrex AGS operates using a sophisticated microprocessor that allows for precise control and adaptability. This technology enables users to customize various settings according to their power needs, ensuring optimal efficiency. Users can also configure the system to respond to temperature or water level conditions, tailoring the performance to specific environments and requirements.

In addition to its automatic functionality, the Xantrex AGS is designed with user-friendliness in mind. A clear, intuitive interface allows for easy setup and adjustments, ensuring that anyone can operate the system effectively. This is particularly advantageous for users who may not be technically inclined or those who are new to generator technology.

Moreover, the system is equipped with advanced safety features that protect both the generator and the connected devices from potential damage. This includes overload protection and additional protocols that prevent the generator from starting during unsafe conditions, providing peace of mind to users.

Overall, the Xantrex Technology Automatic Generator Start system exemplifies a blend of innovation, practicality, and safety features. With its ability to manage power effectively while reducing operational costs, it is an indispensable tool for anyone who relies on a generator for off-grid power supply. Whether for adventures in an RV, tasks on a boat, or maintaining remote properties, the Xantrex AGS stands out as a top choice for reliable automatic generator management.
