Seiwa SW AP01 - Manual (Page 17)

The mechanical limits of the helm are now stored in the autopilot so that the steering drive
stops short of these in operation. The first prompt is:
Turn the helm to the STARBOARD limit. The rudder angle is displayed. If the display
shows port instead of starboard, this will be corrected when STANDBY is pressed.
(Note that if the helm angle is less than 10 degrees at the stop, the system will not respond.)
Press STANDBY and the second prompt is:
Now turn the helm to port until it reaches the mechanical stop. Press STANDBY.
The final prompt is:
Bring the helm to the position which your experience shows to be centred - the indicated
angle may now be different from zero. Press STANDBY.
Warning: This action will start the steering drive. Make sure that it is safe to do so before
pressing STANDBY.
The current helm position is now placed in memory at the helm centre, the helm then moves
to 10 deg port, pauses and then returns to centre. This operation corrects any small
alignment errors in the rudder transducer, stores the correct drive phasing and completes
the setup operation, returning the system to STANDBY.
Note that if the helm is not centred within 5 degrees, the setup will not continue. Press
STANDBY and re-centre the helm by adjusting the rudder transducer. Later, when the
vessel is at cruising speed, it is recommended that the HELM ADJUST option be used to
fine-tune the helm centre. (Sec 2.5).
