Reference Manual 3 Important It is the owner's sole responsibility to install and use the instrument and transducer/s in a manner that will not cause accidents, personal injury or property damage. The user of this product is solely responsible for observing safe boating practices. The choice, location, and installation of all components in any autopilot system is critical. [. . . ] Do not mount the unit with the connectors at the top, because dust or moisture might enter the unit. Reference Manual 11 3-4 Installing the power supplies and steering drive 3-4-1 Installing the power supplies The MCU 600 system requires a light duty and a heavy duty power supply, both 12 V DC. For the heavy duty supply, use the wire size given in the table (see section 3-4-2). Follow the wiring guide (see section 3-2-2). MCU600 Power supply: one switch configuration Choose this configuration to have one switch to turn the PILOT 3300 system and any other instruments on and off. Fit strain relief 12 V DC power supply, current to suit drive Circuit breaker or fuse and switch, current rating to suit steering drive Fuse 1 A Heavy duty Light duty power Connector cover Power supply: two switch configuration Choose this configuration to be able to turn the drive power off and leave other instruments powered. Fit strain relief 12 V DC power supply, current to suit drive Circuit breaker or fuse and switch, current rating to suit steering drive Fuse 1 A Switch Heavy duty power Connector cover Light duty power Note: If powering more than three extra display units or other series instruments, fit another switch and fuse for the light duty power supply for these extra instruments 12 Northstar NS3300 Pilot System Intallation 3-4-2 Installing the steering drive Install the steering drive according to one of the diagrams on the following pages. Wire less than #10 gauge will not fit directly into the four way terminal block. If more than one wire is to be fitted to a terminal of the four way terminal block, join the wires together in a suitable Wire size table To choose a wire gauge for an installation: 1 Measure the length of twin cable required, i. e. the distance from the main control unit to the heavy duty power supply or to the drive. 2 Choose the column with the cable length and the row with the circuit current. The intersection of the row and column gives the preferred (minimum) cable wire gauge for less than 3% voltage drop in a 12 V system. Cable length (from main control unit to power supply or to drive) 0. 7 m Current 1 amp 2 amp 3 amp 4 amp 5 amp 6 amp 7 amp 8 amp 9 amp 10 amp 15 amp 20 amp 2. 5 ft #18 #18 #18 #18 #18 #18 #18 #18 #18 #18 #16 #14 1. 5 m 5 ft #18 #18 #18 #18 #18 #16 #16 #16 #16 #14 #12 #12 2. 2 m 7. 5 ft #18 #18 #18 #16 #16 #16 #14 #14 #14 #12 #12 #10 3m 10 ft #18 #18 #16 #16 #14 #14 #14 #12 #12 #12 #10 #8 3. 7 m 12. 5 ft #18 #18 #16 #14 #14 #12 #12 #12 #12 #10 #10 #8 4. 5 m 15 ft #18 #16 #16 #14 #12 #12 #12 #10 #10 #10 #8 #6 5. 2 m 17. 5 ft #18 #16 #14 #14 #12 #12 #10 #10 #10 #10 #8 #6 6m 20 ft #18 #16 #14 #12 #12 #10 #10 #10 #10 #8 #6 #6 Reference Manual 13 Example of hydraulic steering with hydraulic help pump.

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. 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. 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. 3 Fit the unit as shown below: Rotate base so arrow on arm Set rudder amidships. [. . . ] In normal operation, the PILOT 3300 system will not turn the rudder closer than 3° to an endstop. Warning: Until the rudder feedback unit is calibrated (see section 4-2), there is no rudder limit. The user must ensure that rudder is not driven onto an endstop when using the jog command (see PILOT 3300 Reference manual).
