Test of LF3000/LFI3000 Mk2 feedback
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 and repeat item 2 (See
Figure 3-30). If this gives a better result keep the screen
connected.
Proceed to next menu item by pressing STBD button.
Drive engage
This determines the use of the
autopilot computer drive
engage port. The port voltage
is the same as the selected
drive unit voltage. Drive
engage has the following
settings:
Bypass/clutch:
The port will activate (go high), in all autopilot steering modes,
and typically engages a bypass valve on a hydraulic linear drive
or a clutch on a mechanical drive when entering any of the active
autopilot modes. This is the default setting and it allows you to
steer the boat with the helm or wheel when in STBY or DODGE
modes.
Auto:
This setting is implemented for future use. Always use the
“Bypass/clutch” (default) setting.
