Rudder position sensor (wheel pilot)
NOTE: Not all systems are supplied with a rudder sensor. It is
available separately as part number M81105.
The rudder position sensor connects directly to the boat’s tiller arm or
quadrant. Installing the sensor involves five main steps:
• ensuring correct alignment
• securing the sensor to the boat
• attaching the sensor to the tiller arm
• checking alignment
• connecting to the control unit
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 exceeds +/-5° the ball-joints will bind or fail.
