6 Commissioning
6.1 Commissioning Checks
After installation has been completed, the following checks should be made before use -
1. Installation check - ensuring that the installation of all the components in the system is mechan-
ically and electrically correct.
2. Seatrial - Auto compass calibration. The pilot should be set up for optimum course keeping
ability. If a navigational receiver is interfaced with the pilot, Nav Mode should also be tested.
6.1.1 Installation Check
CABLING
1. Are all the connections secure?
2. Does all wiring meet recommended lengths and sizes for the current/voltage?
3. Does the input power line have the correctly rated fuse or circuit breaker?
4. Where possible, are the cables run away from existing cables which carry radio frequency
or pulsed signals? (1m / 3 Ft distance is recommended).
5. Are cables neatly tied or clamped to prevent friction damage? (Ties every 0.5m / 1.5 Ft
intervals recommended minimum).
6. Are all wire ends tinned?
COURSE COMPUTER SCP12 (AP14H ONLY)
1. Is the Course Computer in a dry location away from excessive heat and vibration?
2. Is the Course Computer mounted on a vertical surface, with the cooling fin uppermost?
3. Is the Course Computer securely attached to a permanent structure?
4. Are all the cables properly fed through the cable clamp channels?
LINEAR FEEDBACK UNIT SLF12 (AP14H ONLY)
1. Has the unit been securely attached to the hydraulic ram of the boat using the supplied
mounting saddles?
2. Is the full stroke of the SLF12 between 150mm and 300mm (6.0in to 12.0in)?
3. Is the SLF12 correctly aligned with the rudder arm?
4. Has it been fitted so that the rod does not bend or distort at any point of steering?
5. When driven hard over from lock to lock, is the SLF12 free from any obstructions?
COMPASS SHS12
1. Has the compass been mounted the correct way up and is it level?
2. Has the compass been mounted in a position away from ferrous materials, loudspeakers,
heavy current carrying cables or other magnetic/electronic equipment to avoid deviation?
3. Has the compass been mounted as near as possible to the centrepoint of the boat to min-
imise heel angle?
HYDRAULIC PUMP (AP14H ONLY)
1. Have the correct fittings been used?
2. Has return line (R) been fitted from the pilot pump ?
3. Are check valves fitted if needed ?
4. Has the system been correctly bled of air ?
5. Is the tubing to the pump high pressure flexible material to reduce vibration?

6.2 Compass Orientation
The SHS12 compass can be mounted pointing
four different ways - 0º, 90º, 180º or 270º to the
bow (Fig 6.1).
• The factory preset is 0º (pointing forward). If
the compass is mounted pointing any other
way, this must be programmed in before using
the pilot.
Press and hold Set until the controller beeps
twice.
Press Set again - the display will show the cur-
rent offset.
Press to adjust the offset in 90º steps to port.
Press to adjust the offset in 90º steps to star-
board - 90º, 180º, 270º.
• If no key is pressed within 5 seconds, the con-
troller will return to the main display and the
orientation currently entered will be set.
6.3 Compass Adjustment
The bearing shown on the AP14 display can be
adjusted by ±15º so that it matches the boat’s
magnetic compass, or a known heading.
• This procedure should be performed after the
compass has been orientated (see section 6.2
above).
Press and hold the
Set
key. The controller will
beep twice and the display will show ADJUST
along with the current bearing detected by the
SHS12 fluxgate compass.
Use the and keys to adjust the displayed
bearing until it matches the boat’s magnetic
compass, or known heading (Fig 6.2).
• If no key is pressed within 5 seconds, the con-
troller will return to the main display and the
bearing entered will be set.
• Note that the bearing can be adjusted by a
maximum of ±15º from the original. If the error
is greater than 15º, check that the SHS12 com-
pass is not receiving interference from nearby
metallic, magnetic or electrical objects.
