[CA] Procedure to align Evolution ACU-150 p70r Auto-Pilot to GPS

[Chuck - Raymarine - Moderator]

Karlista,

Upon completing the installation, did you execute the Dockside Wizard and then take the vessel out for a cruise to permit the autopilot to determine the table of deviation sensed by EV-1 CCU? If so, was the maximum deviation detected less than 10 degrees? Please click here to view a FAQ addressing these items. If the maximum sensed deviation is greater then 10 degrees, then the EV-1 CCU will need to be relocated further away from objects producing magnetic fields.

If the maximum sensed deviation is less than 10 degrees, then heading may be aligned to COG via the command sequence MENU->SET-UP->AUTOPILOT CALIBRATION->COMMISSIONING->ALIGN COMPASS GPS. It is important to note that the vessel must be underway and making way to when aligning heading to COG. It is also recommended that the vessel be steered directly into the current to counter the affect of current induced leeway which may cause COG to differ from heading.
