Sada Reactor™ 40 pro mechanická řízení/retrokompatibilní/elektromagnetickou cívku s přístrojem GHC™ 50

To avoid potential injuries and damage to your sailboat, the autopilot system must be installed by a qualified marine installer. Specific knowledge of marine steering systems and electrical systems is required for correct installation.

For installation, you will need the following tools and supplies:

Safety glassesDrill and drill bitsJigsaw or rotary cutting tool (for optional control instrument installation)Cutting/stripping pliersPhillips and flathead screwdriversCable tiesSolder and waterproof heat-shrink tubing or waterproof crimp connectorsDielectric greaseMarine sealantPortable compass (to test magnetic interference)Note that mounting screws are provided for main components, but you may need to supply screws suitable for your mounting surface if the provided ones are unsuitable.

Yes, the Reactor 40 system is compatible with existing drive units not sold by Garmin, as well as with solenoid drive units. However, specific power cables (sold separately) may be required for the adaptation. Additionally, if you are using a non-Garmin drive unit, you will need to install a Garmin rudder angle sensor (such as the GRF™ 10) or connect an existing three-terminal potentiometer rudder angle sensor, as the system is not compatible with frequency-based sensors.

Yes, this specific kit, the "Reactor™ 40 Kit for mechanical steering systems/backward-compatible/solenoid", includes the GHC™ 50 autopilot instrument, as stated in the product name.

The "Dockside Wizard" is an essential configuration assistant that adapts the autopilot system to your boat's specific dynamics. It can be performed when the boat is docked (in the water or out of the water, but stationary if in the water). This assistant guides you through several necessary steps, including:

Selecting the vessel type.Selecting the drive unit class.Configuring the drive unit and clutch voltage (for non-Garmin units).Selecting the solenoid voltage (for solenoid units).Activating the Shadow Drive™ valve (if installed).Calibrating the rudder angle sensor.Adjusting the drive unit (for non-Garmin units).Testing the rudder direction.Selecting the speed source.Checking the tachometer.These steps are crucial to ensure the autopilot functions correctly.

The "Sea Trial Wizard" is a fundamental configuration procedure that must be performed in calm waters to optimize autopilot performance. It configures the system’s primary sensors and includes critical steps such as:

Configuring the planning mode or maximum speed (depending on the speed source).Calibrating the compass to ensure accurate heading.The Autotune procedure, which automatically adjusts the autopilot’s parameters to your boat’s sailing characteristics by performing zigzag maneuvers.During this procedure, the boat must sail in an open and calm area, with no significant wind, and the onboard weight must remain balanced to ensure accurate results.

No, the power cable for the drive unit cannot be cut or extended. If you are using the autopilot with a drive unit not sold by Garmin or a solenoid drive unit, a drive unit power cable or a solenoid power cable (sold separately) must be used, and these cables cannot be extended either.

The Garmin Reactor 40 kit with the GHC 50 instrument includes the essential components for an autopilot system. It typically contains:

The GHC 50 autopilot instrument (control display)
The Reactor 40 course computer unit (CCU)
The electronic control unit (ECU)
An NMEA 2000 starter kit (cables, T-connectors, NMEA 2000 power cable, terminations)
An audible alarm
The necessary connection cables for the CCU and ECU power supply.
Note: The drive unit (pump or ram) and rudder angle sensor are usually sold separately.

The Reactor 40 autopilot is compatible with the following steering systems:

Yes, to avoid potential personal injury and damage to your sailboat, the autopilot system must be installed by a qualified marine installer. Specific knowledge of marine steering and electrical systems is required for correct installation.

The GHC 50 instrument serves as a dedicated helm control for the Reactor 40 autopilot system. It allows configuration, control, and interaction with the autopilot. It displays essential information and guides the user through setup assistants (Dockside Wizard and Sea Trial Wizard).

No, the drive unit is not included in this kit and is sold separately. If you do not already have a compatible drive unit installed on your boat, you will need to purchase one.

After physical installation, the Reactor 40 autopilot system must be configured and tuned to your boat's dynamics. This setup is performed using two wizards:

The Dockside Wizard: Guides you through initial setup steps that can be completed dockside or out of the water.The Sea Trial Wizard: Configures the autopilot's core sensors and must be run in calm water at typical cruising speed.These wizards are accessible via the GHC 50 instrument or a compatible Garmin chartplotter connected to the same NMEA 2000 network.

Power requirements are as follows:

The electronic control unit (ECU) must be connected to a 12 to 24 Vdc power source. The NMEA 2000 network power cable must be connected to a 9 to 16 Vdc power source.

For optimal performance, the course control unit (CCU) must be mounted in a non-submerged location, near the boat's center, and away from sources of magnetic interference. Additional considerations include:

The CCU must be mounted on a rigid surface. Avoid mounting it within 60 cm (2 ft) of iron, magnets, high-current wires, or pumps operating intermittently. Large magnets (such as those in subwoofers) must be at least 1.5 m (5 ft) from the CCU. The ideal location is closest to the boat's central axis, lower in the boat, and slightly forward. It is recommended to test the location with a handheld compass to detect magnetic interference.

A rudder angle sensor is generally not included in this kit and is often sold separately. However, it is necessary if you are using a non-Garmin drive unit. Garmin recommends the GRF™ 10 sensor. The Reactor 40 system is compatible only with three-terminal potentiometer-type rudder angle sensors; it does not work with frequency-based sensors.

The CCU cable (5 m/16 ft) must not be cut, but extension cables are available if the distance between the CCU and the ECU exceeds 5 meters. The ECU power cable can be extended if necessary, using the appropriate wire gauge. Cables connected to the drive unit (including the drive unit power cable and the cables between the ECU and the drive unit) must not be cut or extended. The ECU must be mounted within 0.5 m (19 in) of the drive unit.

The NMEA 2000 network is essential for communication between the various components of the Reactor 40 autopilot system, including the GHC 50 instrument, the course control unit (CCU), and other compatible marine devices (such as a Garmin chartplotter). It enables the transmission of data required for the configuration, control, and proper operation of the autopilot.

The Shadow Drive™ valve is an optional accessory designed for boats equipped with a hydraulic steering system. It allows you to instantly regain manual control of the helm by automatically disengaging the autopilot as soon as you turn the wheel. It is not included in this kit and is sold separately.

To check for magnetic interference at the CCU mounting location, use a handheld compass. Hold the compass at the intended location, then move it 6 inches (about 15 cm) left, right, above, below, in front of, and behind the location. If the compass needle moves more than 3 degrees during these movements, magnetic interference is present. In this case, it is recommended to select a new mounting location and repeat the test.
