FU DIFF: To be set as required according to the Steering System.
OFF for output of rudder commands in TRANS MODE,
or whether the difference between the
set rudder and actual rudder is to be output for the
control of the steering gear (DIFF MODE).
Hereby, the control loop for the rudder position is closed
via the FU amplifier of the PILOTSTAR D.
For variation, the actual rudder signal must be fed
back via the RUDDER FEEDBACK terminal (refer to
AP02 C S01 HP050).
S_LENGTH: Set to closest available number to vessel length in
METERS.
MAGFILTER: Adjustment to be made, if required, during sea trial after
compass has been compensated -- filters the Magnet LCD
indication only.
RUD SCALE: Set to the greatest rudder angle of the ship.
For a twin rudder system, the parameter is to be set to ”95”
for a rudder angle of 35

or 100 for a rudder angle of 45

.
RUD SLACK: Similar to ”Anti--Hunt”. Increase setting if there is lost
motion in the steering gear causing the rudder to hunt or
oscillate rapidly.
Should also be tested and adjusted, if necessary, in case of
two pump operation.
RUD LEAD: Controls the proper stopping point of the rudder. If the
rudder overshoots 0

(midships) from a

10

rudder angle,
this parameter should be increased.
If the rudder makes an intermediate stop, the ”RUD LEAD”
should be decreased.
RUD SPEED: To be set only in conjunction with the rudder response.
Speed of the rudder in degrees per second. This can be
found by timing the movement of the rudder from 25

port to
25

starboard and dividing 50

by the time recorded.
