Rf300 Installation Manual |work| — Simrad

The Simrad RF300 is a rudder feedback unit designed to transmit the actual position of the vessel's rudder to the autopilot system. In a closed-loop autopilot control system, the rudder feedback serves as the reference sensor. Without accurate rudder position data, the autopilot cannot determine how much the rudder has turned, leading to oversteering, erratic course corrections, or system failure.

Attach the opposite ball joint to the RF300 feedback arm at the matching 140 mm radius point.

Apply a light coat of marine-grade lithium grease to the ball joints once per season to keep motion fluid.

Proper physical alignment is critical to avoid feedback alarms. simrad rf300 installation manual

The RF300 must be mounted in the steering compartment, close to the rudder tiller arm.

The Complete Simrad RF300 Installation & Calibration Manual The Simrad RF300 is a high-precision feedback unit. It measures the exact angle of your boat's rudder. This data is critical for autopilot systems like the Simrad AP11, AP20, AP21, and AP22. Without accurate rudder telemetry, an autopilot cannot calculate correct course corrections, leading to steering lag, weaving, or system failure.

Before beginning the installation, verify that you have all the necessary components and tools. Package Contents The Simrad RF300 is a rudder feedback unit

Navigate to and select Rudder Feedback Calibration . Step 2: Zero Center Alignment Visually confirm the rudder is physically dead-center.

Mount the RF300 near the rudder stock. It must be installed on a flat, stable surface where the transmission link can move freely without hitting the hull or other components. Alignment:

The is a medium-duty rotary rudder feedback unit designed specifically for boats with inboard engines. It provides high-resolution data to your autopilot system, ensuring smooth, accurate steering by determining the precise angle of the rudder. Mounting Instructions Attach the opposite ball joint to the RF300

Check: Ensure the wires are clamped onto the copper strand, not onto the plastic insulation inside the terminal block. Check for corrosion along any wire splices. Set your multimeter to measure Frequency (Hz) .

Careful alignment is necessary during installation. Improper installation can result in constant rudder feedback alarms. 2. Preparing for Installation

While it is a two-wire system, always follow the specific wiring diagram in your autopilot computer manual to ensure the frequency signal is correctly interpreted.

: Modern Simrad systems on smaller boats now often utilize Virtual Rudder Feedback (VRF)
