Rudder position sensor
The rudder position sensor connects directly to the boat’s tiller arm or quadrant.
Installing the sensor involves five steps:
1. Ensuring correct alignment
2. Securing the sensor to the boat
3. Attaching the sensor to the tiller arm
4. Checking alignment
5. Connecting to the course computer
Ensuring correct alignment
CAUTION: Take care to ensure correct rudder sensor alignment. If the sensor
is not correctly aligned, the autopilot system will not perform accurately.
Vertical alignment
When viewed from the front (as shown in the illustration below), the connecting rod should
be as level as possible, so the ball-joints at each end are level. It should also remain parallel to
the tiller arm’s plane of rotation at all times.
Note:
If misalignment e/-5
°
the ball-joints will bind or fail.
