Step 5: Install the Rudder Position Sensor 25
Step 5
3. Drill pilot holes using a 3 mm (
1
/
8
in) drill bit.
4. Attach the tiller pin to the tiller arm using the two self-tapping
screws supplied (No 8 x
3
/
4
inch, countersunk) or suitable bolts,
nuts and lock washers.
Attaching the connector rod
1. Use a hacksaw to cut the threaded connector rod to length.
2. Screw the lock nuts onto the rod and then the ball-pin sockets.
3. Press the sockets onto the pins on the sensor arm and tiller pin.
Note: To give the precise rudder position, the rudder sensor has a
built-in spring to remove any free play in the linkage to the tiller.
Checking alignment
Move the rudder from hardover to hardover and check that at all
rudder angles:
• all moving parts of the sensor remain free from any obstructions
• the sensor and connecting rod remain accurately aligned
• the ball joints do not bind
Connecting to the course computer
1. The rudder sensor is supplied with 10 m (32 ft) of cable. Route the
cable to the course computer, taking into account the EMC
installation guidelines (see page 7).
2. Connect to the
RUDDER terminals on the course computer.
Note: If you have mounted the rudder sensor upside down, you will
need to swap the red and green connections at the course computer.
