Enable Auto (A) Control Mode; Steering In Auto (A) Control Mode - JRC Alphatron AlphaPilot MFS Operation Manual

Table of Contents

The following information is displayed in Auto (A) control mode: actual heading, pre-set heading,

actual speed, actual ROT in degrees per minute or actual RAD in nautical miles, rudder(s) order,

rudder(s) feedback, and steering method.

NOTE: While in Auto (A) control mode, the system continuously checks for the availability and quality

of heading and speed information. In case of no heading data, the audible and visual alert is

generated.

NOTE: A warning message appears on the display if operating parameters 'SET ROT' or 'SET RAD' are

not corresponding with the actual 'Rudder Limit' value. Decrease the value for 'SET ROT' or increase

the value for 'SET RAD'.

NOTE: An alert is generated when the difference between the vessel's actual heading and pre-set

heading exceeds the 'Heading Alarm'.

CONFIRM/SET button, and the Autopilot goes into selected mode (the 'A' symbol appears in

To change the heading, press the LEFT or RIGHT button to select a new heading value, and press the

CONFIRM/SET button to confirm. The autopilot starts changing the actual heading to the new

heading.

In Adaptive Mode, a course change executed by the autopilot system may be

controlled by pre-programmed ROT/RAD data.

NOTICE

These limiting factors can also apply in the Non-Adaptive (PID) operating mode

provided the autopilot has been programmed - for Radius controlled turns - and

that Speed (SOG) input data is available.
