Pilot Display Shows "No Pilot"
Fault Description
No regular messages being received by pilot display from pilot control via instrument system network, i.e.
either the display is not receiving or the Pilot computer is not transmitting.
Remedy
(1)
If other displays show Pilot data, check installation of Pilot display or suspect faulty Pilot display.
(2)
If no Pilot data on any display, check installation of Pilot computer or suspect faulty Pilot computer.
(3)

Pilot does not Steer in a Straight Line
Fault Description
The Pilot seems unable to steer straight, it continually overcorrects course errors; the wake has an "S" like
appearance as the boat first steers several degrees off course to Port followed by several degrees off course
to Starboard.
Remedy
(1)
Drive unit. Check for any slack or backlash in the drive system, see earlier section.
(2)
Rudder reference. Check for any slack or backlash in the assembly and associated linkages, see
earlier section.
(3)
Boat Speed. Check that the boat speed is operating correctly.
(4)
Settings. Read the commissioning manual carefully and check that the settings are appropriate for
the type of boat.
(5)
Rudder gain. Make large course changes using the pilot, if the gain value is correct the rate of turn
should be between 6 and 8 degrees per second. Adjust if necessary.
(6)
Boat lag. A boat lag value that is too small for the boat can cause instability, try increasing the value.
