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.
