Note ! Bring the rudder manually to midship position before starting
the test. If the boat uses power-assist steering, it is important
that the engine or electric motor used to enable the power-assist

Activate the automatic Rudder test by turning the course knob
clockwise.
The AP50 will, after a few seconds, issue a series of PORT and
STBD rudder commands, automatically verify correct rudder
direction, detects minimum voltage for running, and reduce the
rudder speed (reversing pumpset or proportional valves) if it
exceeds the maximum acceptable speed for autopilot operation.
The Rudder test is verified by the display showing ‘Motor OK’,
‘Proportional OK’, ‘Solenoids OK’, or ‘Failed’. If ‘Failed’ is
given, check for correct electrical connection and also make sure
that the steering engine is selected for autopilot control (ref. to
‘System select’ on page 87).
When test is finished the display will read:

The Drive out (displayed in percentage) is the amount of
maximum available voltage needed to achieve correct rudder
speed when automatic steering (Maximum speed is used in NFU
steering).
It will be indicated on the screen whether a clutch is installed or
not.
If the Automatic rudder test fails, refer to ”Warnings” beginning
