Northstar NS3300 Pilot

1 Introduction
The NS3300 Pilot is a superior quality, high performance autopilot display head. The Northstar autopilot system has the flexibility to be used with power or sail boats. The NS3300 Pilot has dedicated performance keys and a large 3.8 Color TFT display. This provides the user with exceptionally easy to use controls. The NS3300 Pilot is part of the Northstar family of instruments for boats, which includes instruments for speed, depth, wind and repeaters. These instruments can be connected together to form an integrated data system for a boat. The autopilots performance is enhanced if it is connected to a boat speed instrument such as a Northstar MULTI 3100 or a GPS instrument. Northstar NS3300 Pilot

1-1 Autopilot Modes 1-1-1 Operating modes
The autopilot has three operating modes (see sections 3-5 and 3-6): STANDBY: The autopilot does not steer the boat STBY (except during jog steer). The helmsman steers the boat with the manual helm. AUTO: The autopilot steers the boat automatically based on selected Steering Mode and course. Do not steer the boat manually. HAND - STEER: The autopilot does not steer the HSTR boat, but displays steering information for you to use to manually steer a course. Steer manually using the displayed steering data.

1-1-2 Steering modes

The autopilot has three steering modes (see section 3-7): Compass: The boat sails at a set compass heading. The boat sails to a destination along a preset route. GPS: This mode requires a GPS instrument, such as a Northstar chart-plotter to be connected via NMEA. WIND: The boat sails at a set angle to the wind. This mode requires a wind instrument, to be connected via NavBus or NMEA.
Note regarding Jog and Follow-up mode: The user is to be aware that while in Standby (STBY) Mode, the autopilot can move the rudder at anytime that the Dodge keys or Control Dial is operated.
1-1-3 Power steering modes
When the autopilot is in STBY (STANDBY) mode the helmsman must steer the boat manually. However The NS3300 Pilot has two different power steering control modes (see section 3-11). Jog: Turns the rudder left or right while the key is pressed.

Follow-up: Sets the target position of the rudder. The rudder will turn until it is in the target position.

Turn modes

The NS3300 Pilot can follow a preprogrammed turn sequence. The autopilot has three different turn modes (see section 3-10): Tack/Gybe: Auto-tacks OR Auto-gybes the boat after a delay period. The tack/gybe angle and tack/gybe delay can be customized. 90 turn: The boat turns through turn: The boat turns through 180 Note: Not all turn modes are available in all operating modes.

GPS gain

In GPS mode, The GPS gain determines how much correction is applied to remove cross track error. A high setting will cause the autopilot to steer quickly back towards the track. A low setting will cause the autopilot to steer very gently back towards the track.

7-3 Wind steering mode

The autopilot has three ways of steering the boat, compass, GPS and wind. To select an appropriate mode, see section 3-7. In wind mode, the autopilot steers the boat to a set angle to the wind, called SWA (set wind angle).

7-3-1 Wind steering data

Course error, 10 to starboard CTS (intended autopilot course, to achieve the SWA [set wind angle])

Boat heading

SWA (set wind angle), 45
Wind angle, can be APP (apparent) or TRUE

APP CTS

Apparent wind angle Course to steer Course error
The apparent wind angle at the boat. P in front of the angle means the wind is from port, S means that the wind is from starboard. The course to steer to maintain the SWA (set wind angle). The difference between APP (wind angle) and SWA (set wind angle). The desired wind angle. The true wind angle at the boat. P in front of the angle means the wind is from port, S means that the wind is from starboard.

SWA TRUE

Set wind angle True wind angle
True and apparent wind speed and direction
Apparent wind speed and direction are the values measured on the boat. True wind speed and direction are the values after allowing for boat speed through the air. If the boat is moving, then the apparent wind speed is different to the true wind speed and the apparent wind direction is different to the true wind direction, as shown below. Boat at rest True wind speed is the same as apparent wind speed and true wind direction is the same as apparent wind direction

Boat is at rest

Boat moving upwind Apparent wind speed is greater than true wind speed and apparent wind direction is closer to dead ahead than true wind direction
True wind direction 45 True wind speed 20 kts True wind speed 20 kts Apparent wind speed 28 kts Apparent wind direction 30 Apparent wind speed 28 kts

steering, decrease counter rudder. For higher boat speeds and large GPS routes, decrease GPS gain; for lower speeds and tight GPS routes, increase GPS gain. For higher and/or more stable winds, increase
wind gain; for lower and/or unstable winds, decrease wind gain. Ideally, in AUTO the autopilot should steer the boat to the course without the rudder moving too often.

8-2 Profiles

The autopilot provides five configurable steering profiles that can be quickly recalled to alter the autopilots performance based on changing sea, environmental and vessel conditions. To change a profile go to: Menu > Setup > Profiles > Profile menu. Each of the five profiles can be individually named and configured with different steering performance settings, and recalled as needed. To name the currently selected profile, go to Menu > Setup > Profiles > Edit name then: Use the Control Dial, and keys to edit the name of the profile. Rotate the control dial to select numerical and upper and lower case alphabetical characters. Maximum number of alphanumeric characters is 8. to finish editing. Repeatedly press Note: When using more than one NS3300 Pilot, profile names are not transferred between units. So when naming profiles, be sure to name the profile on each NS3300 Pilot. How to use profiles: 1. When the autopilot is installed, the steering parameters in all the profiles are set to their default values. 2. Select User 1, and adjust the steering parameters for optimum steering in typical conditions. 3. If the conditions change and the steering is no longer optimum, select another profile and adjust the steering parameters again Repeat this step as required to adjust the parameters in each profile. 4. When using the autopilot to steer, select a profile suitable for the current conditions. For example different profiles can be configured for rough conditions and calm conditions, sailing or motoring.
8-3 Adjusting the steering parameters
Problem: rudder turns too frequently
This causes wear on the steering linkage and uses power. Decrease response. Reduce ratio. Reduce counter rudder gain.
Problem: drifts off course to one side
Increase ratio. Increase trim gain. or Increase response.
Problem: boat moves too far off course closely before the rudder turns to correct the course
Decrease ratio. Decrease counter rudder gain. Decrease trim gain.
Problem: oscillations from side to side build up

Decrease ratio.

Problem: after a large course change, boat overshoots and oscillates before settling to new course
Increase counter rudder gain
Problem: after a large course change, boat takes too long to settle to new course
Decrease counter rudder gain
Problem: after a sideways current or wind, the correction is applied too quickly or too slowly If the boat encounters a sideways force, then it will move off course sideways. The Pilot will automatically bring the boat back to the correct heading by applying a few degrees of rudder, called trim. Trim gain sets how quickly the trim is applied. Trim gain should be adjusted to trim the boat in about one minute. Getting the Trim gain setting right can be difficult for your specific boat and it is easy to alter the Trim gain too much. Change the settings slowly and conservatively at first, until the right settings are known.
a Boat takes much more than one minute to trim

Sideways force starts

Increase trim gain
1 minute Boat takes much less than one minute to trim
Sideways force starts Decrease trim gain

1 minute

Problem: drifts off GPS course

or Increase GPS gain.

Problem: boat oscillated around GPS course

Decrease GPS gain.

Using the PILOT 3300 system :
The PILOT 3300 system is intended as an aid to save a helmsman from having to steer for long periods of time, not as the main means of steering the boat. The PILOT 3300 system is not intended for use in extreme weather, in adverse conditions or in water near other boats, dangerous waters or land. The PILOT 3300 system can not control the boat better than a helmsman. In adverse conditions steer the boat manually. Never leave the helm unattended. Keep a watch at all times. The helmsman should always monitor the course of the boat and the PILOT 3300 system and be ready to resume steering the boat manually. The performance of the PILOT 3300 system can be affected by the failure of a part, environmental conditions, improper installation and use.

1-2 Using the PILOT 3300 system with other instruments
1-2-1 Using other instruments
The PILOT 3300 system can use data from these instruments: GPS: A GPS or chartplotter, such as a Northstar 6000i chartplotter must be connected to the PILOT 3300 system for the PILOT to operate in GPS mode (see the PILOT 3300 Reference manual). Note: GPS must be via NMEA input. WIND: A wind instrument, such as a Northstar WIND series, must be connected to the PILOT 3300 system for the PILOT to operate in WIND mode (see the PILOT 3300 Reference manual). SPEED: A speed instrument, such as: Northstars MULTI with a paddlewheel speed sensor or a GPS or chartplotter, such as Northstars 6000i series can be connected to the PILOT 3300 system to increase steering accuracy. Note: The speed from a paddlewheel sensor is the speed that the boat is moving through the water. The speed from a GPS is the speed over the ground. If there is a water current then these two speeds will be different. If the PILOT 3300 system is connected to an instrument with a paddlewheel sensor and to a GPS, then the PILOT 3300 system will automatically use the speed from the paddlewheel sensor instrument.

1-2-2 NavBus

NavBus is a Northstar proprietary system that allows systems of multiple instruments to be built using a single set of transducers. When instruments are connected by NavBus: If you change the units, alarms or calibration in one instrument, then the values will automatically change in all other instruments of the same type. Each instrument can be assigned to a group of instruments, called a NavBus group (see NavBus group in the Setup > Comms menu, in the PILOT 3300 Reference manual). If you change the backlight in an instrument in group 1, 2, 3 or 4 then the backlight will automatically change in the other instruments in the same group. If you change the backlight in an instrument in group 0 then no other instruments are affected. If an alarm sounds, mute it on any instrument which can display that alarm. For more information, refer to the NavBus Installation and Reference manual.tt Note: GPS must be via NMEA input.
NavBus and the PILOT 3300 system
The PILOT 3300 system will automatically work with additional PILOT 3300 displays. The PILOT 3300 system can receive wind data from Northstars WIND over NavBus. The PILOT 3300 system can receive speed data from Northstars MULTI over NavBus.

1-2-3 NMEA

NMEA is an industry standard, but is not as flexible as NavBus as it requires dedicated connections between instruments. The PILOT 3300 system has one NMEA input port and one port that can be configured to be an input or an output (See PILOT 3300 Reference manual).
PILOT 3300 system NMEA inputs
GPS: The PILOT 3300 system can receive NMEA GPS data from a compatible GPS or chartplotter, such as Northstars 6000i series chartplotter: XTE (from APA, APB or XTE sentences) is required for the PILOT 3300 system to use GPS mode BRG (from APA sentences) and BOD (from APA or APB sentences) are optional and improve performance COG (from VTG sentences) is optional and can be displayed. WIND: The PILOT 3300 system can receive NMEA wind data from a compatible wind instrument: True or apparent wind direction (from MWV sentences) is required for the PILOT 3300 system to use Wind mode. SPEED: The PILOT 3300 system can receive NMEA speed data from a compatible paddlewheel or GPS instrument: SOG (from VTG sentences) is optional and improves performance. Note: If the PILOT 3300 system is connected to a Northstar series wind or speed instrument using NavBus, then the PILOT 3300 system will automatically receive and use the wind or speed data, and the NMEA connection need not be wired.
PILOT 3300 system NMEA outputs
The NMEA 2 port can be configured to be an input or to be output: either heading (HDG & HDT) and rudder angle (RSA) at once per second or heading (HDG) at ten times per second (see NMEA mode in the Setup > Comms menu, See PILOT 3300 Reference manual).

2-2 Other parts required

Power supply: The PILOT 3300 system requires two power supplies, both nominally 12 V DC: A heavy duty supply for the steering drive A light duty supply for the PILOT 3300 system electronics and display unit; this supply also powers any additional display units and other instruments. The power supplies require one or two switches and fuses or circuit breakers (see section 3-4). Steering drive: The PILOT 3300 system can power a hydraulic pump, constantly running pump set, hydraulic linear drive or mechanical drive rated at 12 V DC and up to 20 A. Rudder linkage: To link rudder to rudder feedback unit (see section 3-5). For wiring, see Select Wire Table in section 3-4-2. External beepers or lights (optional ): The external output is switched to ground, 30 V DC and 250 mA maximum. If the beepers and lights require more than 250 mA total, fit a relay. Other marine instruments (optional): Wind, speed or GPS instruments can be connected (see section 1-2). Other parts: For systems of several instruments, wiring and connectors are required. Northstar junction boxes can simplify wiring several Northstar instruments together (see section 1-2 or the NavBus Installation and Reference manual). Coupling connectors and 10 m (33 ft) extension cables are available to extend the rudder feedback unit, compass or gyro cables. Do not fit more than one extension cable to each unit. For more information, consult your Northstar dealer.

3 Installation

Warning: Correct installation is critical to the performance of the unit. It is vital to read this manual and the documentation that comes with the other parts before starting installation. Warning: The MCU600 is not waterproof. Mount the unit in a dry place. The PILOT 3300 system display unit is waterproof. The compass, gyro and rudder feedback unit are completely waterproof. Warning: Ensure that any holes that you cut will not weaken the boats structure. If in doubt, consult a qualified boat builder.
3-1 Installation sequence
The recommended installation sequence is: 1 Read this manual and the documentation that comes with the other parts. 2 Plan the installation: select where the equipment and wiring will be installed (see section 3-2). 3 Install the MCU600 (see section 3-3). 4 Install the steering drive and wire the heavy duty and light duty power supplies (see section 3-4). 5 Install the rudder feedback unit (see section 3-5). 6 Install the compass (see section 3-6). 7 Install the gyro (see section 3-7). 8 Install the display unit and any other marine instruments that will be used with the PILOT 3300 system (see section 3-8). 9 Carry out the dockside setup (see section 4). 10 Carry out the sea trials (see section 5). If you are unsure where a part should be installed, mount and wire the part temporarily, without cutting holes in the boat. After the sea trials have been completed, install and wire the part permanently.

3-2 Installation guide

This is a general guide for locating and wiring the parts of the PILOT 3300 system. The instructions for a particular part may have additional requirements.

3-2-1 Location guide

Do not mount any part where it can be used as a handhold, where it will interfere with the operation of the boat or where it might be submerged. Do not mount any part where it will interfere with launching or retrieving the boat. Do not mount any part within 0.5 m (20) of the plane of a radar antenna. Mount the compass and gyro: At least 1 m (3 ft) away from sources of electrical signals or noise, such as the batteries, high-current cables, other boat cables, engines, fluorescent lights, power inverters, radio or radar transmitters and antennas. At least 1 m (3 ft) away from equipment containing a magnet, such as a compass or speaker.

3-2-2 Wiring guide

The PILOT 3300 system has two kinds of cables: The heavy-duty power supply and steering drive usually require high-current cables: Select the wire gauge from the wire size table (see section 3-4-2). Fit high-current cables at least 1 m (3 ft) away from other electronic devices in the boat. Keep the cables as short as possible. Twin 2 mm (#14) cable is supplied with the PILOT 3300 system and can be used for the high current cable if its gauge is suitable. All the other cables are low-current: Fit low-current cables at least 1 m (3 ft) away from sources of electrical signals or noise, such as the highcurrent cables, other boat cables, engines, fluorescent lights, power inverters and radio or radar transmitters and antennas. If the cable for the rudder feedback unit, compass or gyro is too long, do not shorten the cable; instead coil the cable up near the main control unit. The cable for the rudder feedback unit, compass or gyro can be extended by adding a 10 m (33 ft) extension cable and coupling connector. Do not fit more than one extension cable to each unit. When fitting any type of cable: Do not crush, pinch or strain the cable. Secure the cable at regular intervals. Ensure no connectors or exposed terminals are in the bilge.

Note If you move the gyro with respect to the compass while the power is on, wait for the heading to stabilise.
3-8 Installing the PILOT 3300 display unit and other instruments
There are two mounting arrangements: Flush mounting requires a solid panel with access behind for wiring and mounting screws. After flush mounting, the display cannot be tilted or moved after installation to reduce any unwanted glare or reflections. Carefully select the best viewing position before installation. This would generally be in a shaded area.
Flush mounting directions 1 Cut a hole in the bulkhead for the display unit using the flush mount template as a guide. 2 Drill four holes for the mounting studs using the flush mount template as a guide. 3 Screw the four studs into the brass inserts in the back of the display unit. 4 Sit the display unit in place and fit the washers and nuts to the studs. Bracket mounting requires a panel for mounting the bracket. Ensure that the panel is not likely to deform and is not subject to excessive vibration. The bracket can be tilted and the dispaly can be removed after each use. At least 4" (100 mm) away from the compass. At least 12" (300 mm) away from any radio transmitter. At least 4 ft (1.2 m) away from any antenna. Easy to read and operate. If possible, mount the display unit in front of the navigator or to the right of the navigator because the LCD display is more readable from these positions. Not exposed to the direct sun or water. Protected from physical damage during rough sea passages. Easy to access the DC power source. Convenient to route the transducer cables. Bracket mounting directions 1 Fix the mounting bracket onto the boat using the four stainless steel screws. 2 Hold the display unit in place in the mounting bracket. Fit the mounting bracket knobs into the display unit and do up the knobs loosely. 3 Adjust the tilt of the display for best viewing, then hand tighten the knobs on the mounting bracket.

Select a position where the display unit will be:

4 Dockside setup

Perform the dockside setup: after installing a PILOT 3300 system (see section 3) after a part has been changed or if a problem is suspected After dockside setup, perform the sea trials (see section 5 ).

4-1 Start dockside setup

1 Turn the PILOT 3300 system on (See PILOT 3300 Reference manual). If the rudder moves, immediately turn the power off. If you try to enter AUTO and the rudder feedback unit or compass have not yet been calibrated, then the PILOT 3300 system will displays an error. 2 If the PILOT 3300 system has been used before, reset all user data to the factory defaults. Go to Factory reset > Both in the Setup System menu (See PILOT 3300 Reference manual). 3 Enter the user data listed in the User Data table below (See PILOT 3300 Reference manual to find what each data item means and how to enter the data). Beside each item, write the value of the user data that you enter.
4-2 Calibrating the rudder feedback unit
To calibrate the rudder feedback unit go to Rudder in the Setup > Calibrate menu. Follow the on-screen instructions presented by the calibration wizard (See PILOT 3300 Reference manual). This procedure matches the rudder feedback unit to the rudder. Note To exit the calibration at any time, press ESC. If you do not move the rudder as prompted or the rudder feedback unit is not working then the PILOT 3300 system can not nish the calibration. The PILOT 3300 system will display an error. Press ESC, x the problem and repeat the calibration. 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).

5 Sea trials

Perform the sea trials: After performing the dockside setup (see section 4). To check the operation of the PILOT 3300 system. For the sea trials, sail in an open area where there are no other craft or obstructions. The sea should be calm, the wind speed as low as possible and there should be no currents.
5-1 Calibrating the compass
Note To calibrate the Compass unit go to Compass in the Setup > Calibrate menu. Follow the on-screen instructions presented by the calibration wizard (See PILOT 3300 Reference manual). To exit the calibration at any time, press ESC. If the boat is not turned as prompted or the compass is not working then calibration can not be completed, the PILOT 3300 system displays an error. Press ESC, x the problem and repeat the calibration. Local disturbances in magnetic eld may affect the compass. 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 vessels compass then ensure that the deviation tables are applied to check the autopilots 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)
