2.29 (iii) To calibrate Adaptive Autopilot Steering vs Speed:-
Calibration parameters 4, 5 and 6 require minimum, normal working and maximum vessel
speeds in a fully laden condition.
(a) Engage the Autopilot system (ON key) and manually adjust the PID controls for
optimum steering performance (sections 2.19 – 2.25 refer) at the lowest realistic
working speed likely for Autopilot control.
(b) Enter controls menu by pressing CONTROLS key and ensure ADAPT value box is
flashing. Simultaneously press CONTROLS and LIMITS keys for a period of 5
seconds to enter the Adaptive calibration mode confirmed by ADAPT followed by
a flashing CAL1 message.
(c) Use the rotary illumination (±) control to step through to parameter ‘CAL4’.
(d) With the vessel at minimum operating speed and the autopilot steering
performance optimised (per item (a) above) use the CONTROLS key for 5
seconds to ‘capture’ the Autopilot control parameters/speed correlation
commensurate with this speed.
(e) Repeat (c) and (d) at normal working and maximum speeds in the fully laden
condition to calibrate CAL5 and CAL6 requirements respectively.
NB. If draft input data is available, remain in the Adaptive Calibration mode to calibrate CAL7,
CAL8 and CAL9. (Section 2.30)
(f) Enter controls menu by pressing CONTROLS key and ensure ADAPT value box is
flashing. Exit the Adaptive calibration mode by simultaneous 5 second operation
of the CONTROLS and LIMITS keys confirmed by normal operating display
presentation.
(g) Use the ‘CONTROLS’ key to display the CONTROLS menu and use the rotary
illumination (±) control to set the flashing ADAPT box condition to ‘ON’.
The Autopilot system is now calibrated and set to work in the Adaptive mode but it should be
noted that entry to the ‘CONTROLS’ menu (CONTROLS key operation) will permit manual
intervention/update of any current control parameters (RUDDER, COUNTER, YAW etc.) at any
time if required.
