Motor Relay coil 1N4002 diode or equivalent. Fit close to relay coil Note: Relay is required if the clutch circuit is greater than 300 mA. Installing a continuous running pump and solenoid valves. In the Setup > Vessel menu (See PILOT 3300 system Reference manual), set Drive Type to Spool ground. MCU600 Fit strain relief Heavy duty power (see section 3-4-1) Relay contacts Connector cover Note: Motor is not required for engine PTO systems. Motor Wiring polarity does not matter. Relay coil 1N4002 diode or equivalent Starboard Port Fit close to relay coil Note: Relay is required if the clutch circuit is greater than 300 mA. Reference Manual 15 Installing solenoid valves or relays with jog or electric steering In the Setup > Vessel menu (See PILOT 3300 Reference manual), set Drive Type to Spool ground.

End of connecting rod snaps into one of the Connecting rod, with quick release fittings and lock nuts each end holes on the arm. Mounting requirements These two distances to be equal. These two distances to be equal. Adjust position of rod on arm if required. Rudder shaft to be parallel to shaft in base. Base to be adjacent to rudder shaft so that this angle is 90° Cut connecting rod if required. Rudder linkage and arm to move in the same plane Thread = M5 Note The unit is completely waterproof but should not be immersed. Mount the unit on a panel which does not vibrate. Follow the location guide (see section 3-2-1). Reference Manual 17 Alignment The arm can rotate freely around the base. When the rudder is amidships, the arrow on the arm must point to one of the centre lines on the base. Centre line Base Centre line Sets of lines show the two linear ranges of the unit. Therefore in an installation, the base can be rotated to two positions. We recommend the position that has the cable on the opposite side to the connecting rod. Recommended (rudder amidships). Not recommended, cable can foul rudder linkage. Arrangements Recommended: U-shaped arrangement with the arm parallel to the length of boat: Bow of boat Satisfactory: U-shaped arrangement with arm not parallel to length of boat, for example: Not recommended: Z-shaped arrangement, for example: Bow of boat If rudder turns too far, the unit might not return to the Z shape. 18 Northstar NS3300 Pilot System Intallation Installation 1 Find a suitable location and arrangement for the unit as described above. 2 Choose, assemble and fit a suitable rudder linkage. 3 Fit the unit as shown below: Rotate base so arrow on arm Set rudder amidships. If necessary, mount base on block to set height. [. . . ] Calibration must be preformed away from large metal structures such as marinas, large ships etc. ; this is the responsibility of the user. Ensure that both sources are referencing the same north (true or magnetic). If your magnetic compass has not been calibrated then you can use another source for heading. If using vessel's compass then ensure that the deviation tables are applied to check the autopilot's compass. 5-2 Aligning the compass and the rudder The compass or rudder can be aligned separately. 5-2-1 Aligning the compass (Align heading) This aligns the PILOT 3300 system compass to display the correct heading.
