ComNav 1500 - Sea Trials and APC Calibration

ComNav 1500 / 1510 Autopilot - 45 -
8. SEA TRIALS
8.1 Preparations
Take your boat out at half speed to calm seas away from other boats or
obstructions to run the sea trials. Then proceed as per below.
Warning! Do not activate any of the Autopilot functions (Compass, Nav or Wind) at
dockside as the rudder may go hard over, since the APC routine has not been
carried out yet.
8.2 Compass Calibration
Enter the compass calibration.
Note! If you are using an existing NX2 Compass transducer that already has been
compensated, it is not necessary to run the auto-deviation [Auto DEV] procedure
again.
Local Magnetic Variation:
Run the calibration routine local variation [VAR].
Automatic Compass Compensation:
Run the calibration procedure auto-deviation [Auto DEV].
Automatic Compass Check
Run the calibration procedure auto-deviation-check [Auto CHK].
Misalignment Correction
Run the calibration procedure compass alignment [ADJ].
8.3 Automatic Pilot Calibration [APC]
The Autopilot will not function unless the boat pass the APC routine. The APC will
automatically determine and correct how wires and pipes are connected. It will also
learn how the boat reacts on different rudder commands and automatically calibrate
itself.
The APC routine automatically sets: [RUD], [SEA], [CRD], [ATC] and [RRS].
Select P7 [APC]. To unlock, press SET. To change to [On], press LEFT or RIGHT.
To activate the APC, press SET.
All 4 page arrows at top of display will now be lit to confirm the APC procedure is in
action.
The boat should automatically turn slightly to port and starboard and return to
original course.
