Rudder deadband
The rudder deadband function is adaptive and is continuously
updating. It prevents the rudder from hunting and the adaptive
function optimizes the deadband to the speed of the boat and the
load on the rudder.
If the auto-setting does not perform properly due to high inertia
from the wheel, it can be adjusted manually.
Find the lowest possible value that will prevent the rudder from
continuous hunting. A wide deadband will cause inaccurate steering.
It is recommended to check rudder stability in Auto mode when the
boat is moving to get pressure on the rudder.

Rudder Test
 Note:
If the boat uses power assisted steering, it is important that the
engine or electric motor used to enable the power assist steering be
turned on prior to this test.
Warning: Stand CLEAR of the wheel and do not attempt to take
manual control of the wheel during this test!
Bring the rudder manually to midship position before starting the
test.
After a few seconds the H5000 Pilot Computer will issue a series
of port and starboard rudder commands and automatically verify
correct rudder direction.
It detects minimum power to drive the rudder and reduces the
rudder speed if it exceeds the maximum preferred speed (8°/sec.) for
autopilot operation.
The Rudder test is verifi ed by the display showing Completed Rev.
motor, Completed Solenoids, or Failed. If Failed is displayed, check for
correct electrical connection.
