All new spares PCBs are factory set to operate the pilot with the drive unit
facing aft. A replacement PCB for an installation with the drive unit facing
forward requires resetting.
To reset the operating sense press the +1° and -1° course keys together for
5 seconds.
The unit beeps for 10 seconds to confirm changeover and the display shows
the new setting, either ‘Port’ (actuator sprocket facing forward) or ‘Starb’
(actuator sprocket facing aft’).
The autopilot may be calibrated t to suit a particular vessel. Note the
calibration settings and set up the new PCB if required.
If the spares PCB contains software of a higher issue than before then the
relevant Operating Supplement must be supplied when the equipment is
returned to the customer.
Note: Replacement PCBs require setting up to ST3000.
