If no adjustment has been made to the display readout (i.e. not
turning the course knob), the AP50 will set the physical stop to
45°. "Max. rudder limit" will be set to 2° less.
Rudder-zero may still be inaccurate and should be adjusted
later during sea trial.
Proceed to the next menu item (Rudder Test) by pressing the
(STBD) button.

Rudder Calibration

(Applies for JD53 Distribution Unit only)
All required adjustments for both voltage and current are set via
the Installation menu and therefore no adjustments of the PCB
trim potentiometers shall be made.
There is a common setting of max. port and stbd. rudder angle
for both rudder drives. The amount of voltage or current
corresponding to max port and stbd travel for each rudder drive
is however set individually.
Use the following procedure for calibrating the rudders:
Enter "Installation, Dockside menu and select "Rudder Max
STBD".
Turn the course knob and set the required max rudder travel to a
little less than the extreme hard-over position.
Press the (STBD) button to enter "Rudder Max PORT" Turn
the course knob and select max travel to port. Note that this sets
the maximum travel for rudders or azimuth thrusters whichever
is applicable.
Press the (STBD) button to enter "Cal rudder drive 1".
Turn the course knob CW and observe that the display shows
"Set max Rudder STBD Voltage output".
Turn the course knob to obtain STBD rudder by turning the knob
CW or CCW. Observe the rudder angle indicator and output
voltage and continue to turn the course knob until the rudder has
reached the previous selected maximum angle to STBD.
