NT888G MK2 AUTOPILOT OPERATING MANUAL
2.29 (ii) Calibration of Power Steer Override Controls vs Speed:-
(a) Use the Autopilot STBY key to enter the Standby mode. Enter controls
menu by pressing CONTROLS Key.
(b) Press
the CONTROLS and LIMITS keys simultaneously for a period of
5 seconds to enter the Calibration mode confirmed by the ADAPT box
showing ‘CAL1’ . (FIG 2.29(ii) refers).
(c)
Set the speed of the vessel at the lowest realistic working speed likely
for Autopilot control and – using manual steering control(s) – enter and
maintain the vessel in a turn at the maximum safe level (rate of turn)
commensurate with this speed.
(d) Use
the CONTROLS key for a period of 5 seconds to ’capture’ the
Rudder angle/speed data for future Autopilot Override control use
confirmed when completed by the display message
‘CAL2’ .
(e)
Repeat (c) and (d) at normal working speed and maximum speed (CAL2
and CAL3 respectively) to capture and store the related Rudder/Speed
data.
(f)
Enter controls menu by pressing CONTROLS key and ensure ADAPT
value box is highlighted. Simultaneous 5 second CONTROLS and
LIMITS key operation to exit the calibration mode.
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 highlighted. Simultaneously press CONTROLS and
LIMITS keys for a period of 5 seconds to enter the Adaptive calibration
mode confirmed by ADAPT followed by a highlighted CAL1 message.
(c)
Use the rotary illumination (±) control to step through to parameter
‘CAL4’ . (FIG 2.29 (iii) refers).
(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)
