Cablesteer rudder calibration
1. Select Commissioning.
2. Select Rudder feedback calibration.
3.
Follow the onscreen instructions.
Ú Note:
When centering the motor during the calibration
process, ensure that the motor is centered visually. The rudder
feedback calibration dialog may show the motor is centered (00
value) when the motor is not centered. After centering the
motor visually, press OK and the rudder center calibration
setting is set to centered (00 value).
4. Select Rudder test.
5.
If the calibration does not pass the rudder test:
- Confirm motor is moving.
- Confirm rudder feedback reading moves accordingly.
- Check NAC-1 drive cable.
- Confirm motor can be manually moved smoothly in each
direction.
- Check for other mechanical issues.
- Check wiring connections.
- Repeat rudder calibration steps.
Hydraulic system calibration
Virtual rudder feedback (VRF) calibration is used for vessels with
hydraulic steering.
1. Select Commissioning.
2. Select VRF calibration.
3.
Follow the onscreen instructions.
Ú Note:
When the autopilot attempts to turn the motor during
the calibration process, ensure motor movement is noticeable
and that it is turning in the correct direction before selecting
Yes on the Virtual Rudder Feedback Calibration dialog. When
No is selected in the dialog, the NAC-1 reverses direction and
increases power the next time it turns the motor during the
calibration process.
Ú Note: You may have to select No more than once to ensure the
pump provides enough power to turn the motor at high boat
speeds.
