Rf300 Installation Manual | Simrad

The RF300 should be mounted at a height that keeps the transmission link rod as horizontal as possible. A steep vertical slope on the rod will cause binding and wear out the internal components of the RF300. 3. Step-by-Step Mechanical Installation Step 1: Secure the Rudder at Midships

Ensure the cable is clamped to allow for full rudder movement and include a "drip loop" to prevent water from following the cable into the unit. 3. Calibration and Testing

Turn the helm slowly to hard-over Port. Stop when the rudder hits its physical stop.

The RF300 is designed to be maintenance-free. The installation manual stresses that the transmitter arm should from the feedback unit, as it is factory-calibrated and sealed. Because of its frequency-based design, there are no internal pots to wear out. The only regular check needed is to ensure the linkage rod and ball joints remain lubricated and free of corrosion. simrad rf300 installation manual

The RF300 uses a simple three-wire connection to send data to the autopilot computer.

Turn the helm slowly to hard-over Starboard until it hits the physical stop.

Apply a light film of marine-grade lithium grease to the ball joints annually. The RF300 should be mounted at a height

Inspect the ball joints on the linkage rod. Lubricate them with a high-quality, water-resistant marine grease.

Whether you’re a seasoned sailor or a weekend cruiser, few things are more frustrating than an autopilot that can’t find its "center." If your Simrad system is acting twitchy, it’s time to talk about the unsung hero of the helm: the RF300 Feedback Unit

Move the steering from port to starboard to ensure the transmission link does not hit any components or pass "over dead center," which could block the system. 2. Electrical Wiring Stop when the rudder hits its physical stop

Connect the ball joints to the rudder tiller arm and the RF300 arm.

transmitter lever until it is also in the center position. Use the alignment marks on the unit to ensure the lever is opposite the cable entry, or, on some models, in line with the marked centre position.

The RF300’s job is to tell your autopilot exactly where your rudder is pointing. To do that accurately, it needs to be mounted on a flat surface, usually near the rudder post or steering quadrant.

The RF300 uses a two-wire, non-polarized frequency signal. This means wire color polarity at the autopilot computer terminal strip is generally interchangeable, but standard practices should be followed for troubleshooting purposes.
