Advanced Menus
(Pilot Setup Explained)
USE RFU
Values: YES / NO Default: YES
Enable only if a RFU is connected.
Note that if the RFU is enabled
and the RFU fails, the system will
automatically revert to NON-RFU
mode. Therefore it is recommended
to test and sea trial both modes with
thissettingo󰀨andon.
SWAP DRIVE OUTPUT
Values: YES / NO Default: NO
A handy function to reverse the motor
drive output in case the motor is
driving in the wrong direction.
SOLENOID
Values: NEGATIVE / POSITIVE
Default: NEGATIVE
For setting the drive output polarity
for solenoid drive systems.
Set to Negative if solenoids have
a common positive connection to
battery
Set to Positive if solenoids have a
common negative connection to
battery
DEAD BAND
Range: 1 – 20 (degrees) Default: 10
Adjusts the amount the rudder is
allowed to “wander” before the
autopilot reacts to correct any
change. This value has a similar
e󰀨ecttothe‘Sensitivity’settinginthe
primary PILOT Settings.
REVERSE DELAY
Range: 1 to 99 Default: 5
Sets the time delay when the
SP120C changes the motor direction
(i.e. Port to Starboard or Starboard
to Port changes) this setting can
prevent shock load and over current
on the drive output, since reversing
motors and solenoids need time
to discharge before driving in the
opposite direction.
PULSE SIZE:
Range: 1 to 50 Default: 15
When the vessel is near to the
desired position/course, the drive
motor will be pulsed to make minor
adjustments. A larger pulse size
may be required for less responsive
vessels with slower steering pumps.
(E.g. larger boats with high rudder
inertia require larger pulse size
values.)
OFFCOURSE ALARM
Range: 1 to 180 (degrees) Default: 45
The SP120C system will alarm when
thedi󰀨erencebetweenthevessels
heading and desired course to steer,
is greater than this value.
