Attaching the connector rod
1. Use a hacksaw to cut the threaded connector rod to length.
2. Screw the lock nuts onto the road 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 control unit
1. The rudder position sensor is supplied with 10 m (32 ft) of cable.
Route the cable to the control unit, taking into account the EMC
installation guidelines (page 46).
2. Connect the four cores of the cable (color for color) to the Rudder
terminals on the control unit as shown.
Note: If the standard cable is not long enough, your Raymarine
dealer can supply a 10 m (30 ft) extension cable (part number: D173).
