Note ! Move the rudder manually to midship position before
starting the test. It is important also that if the boat uses
power assist steering, that the engine or electric motor
used to enable the power assist steering be turned on
prior to this test. Stand CLEAR of the wheel and do
not attempt to take manual control of the wheel
during this test!
Activate the flashing display by pressing MODE.
Acknowledge by pressing > (Yes) or < (No). Start the rudder
test by pressing MODE. The display will be flashing ON
and the AP11 will issue a series of PORT and STBD rudder
commands to automatically verify correct motor direction,
and reduce the rudder speed if it exceeds the maximum
acceptable speed for autopilot operation.
When the test is finished the display will read dONE (SOL
if connected to solenoid valves).
Note ! If the display reads SLO, the rudder speed is less than
1°/second and you must check your drive unit for
improper operation or lack of power or capacity.
LFI3000 Mk2 additional test
1. Align engines to centre position; “zero rudder”.
2. Rev engines to 3-4000 rev/min and observe the rudder angle
indicator on the autopilot, a 2° change in the reading should
be accepted.
3. If the rudder angle exceeds 2°, connect the screen on the TB1
cable to the centre block terminal (See Figure 37) and repeat
item 2. If this gives a better result keep the screen connected.
After the above dock-side settings are completed, the
autopilot can be operated in the normal way even if some
adjustments remain before the installation setup is
completed.
