[. . . ] When changes in vessel trim occur due to variations in wind pressure or engine throttle setting the course can only be maintained by the application of permanent rudder. off-set (standing helm) to restore balance. If permanent rudder off-set is not applied to restore balance the vessel will bear on to a new heading. Under these circumstances the Autohelm PowerPilot detects that the original course is not being restoredand continues to apply additional rudder off-set in the appropriate direction until the vessel returns to the original heading. Automatic trimming capability ensures that the originally set course is held irrespective of any changes in balance that may occur during the course of a passage. Autohelm PowerPilot's central computer also continuously monitors the pattern of applied rudder correction and can distinguish unnecessary repetitive corrections caused by pitch and roll of the 1 J vessel from those necessary to maintain the selected heading. If unnecessary repetitive corrections continue the computer will automatically neglect them so that autopilot activity and power consumption is continuously optimised at minimum levels. The high degree of control automation made possible by the system's central micro computer simplifies user control to a series of push button operations. ELECTRONIC POWER SUPPLY 22 Fig. CIRCUIT BREAKER 25AMP- 12V H E A V Y DUTY POWER SUPPLY OUTPUT TO MOTOR 16 17 3. 2. 3 Operating Mode indication and Course Display The operating mode of the autopilot is indicated by a flashing red LED, as summarised below:- 3. 2. 4 Off-Course Alarm When the autopilot is set to Auto mode a built in off-course alarm is automatically set up. The off-course alarm will sound from all control units when the vessel deviates for any reason from the original course by more than 15" for over 20 seconds. If an auxiliary alarm is fitted this will also be sounded after a one minute delay to allow the watchkeeper to take corrective action. The alarm will be silenced if the vessel returns to within 1 So of the original course. If the vessel does not return within course limits the alarm can only be silenced by disengaging the autopilot and resetting a new course. f$j l If the rudder immediately drives hard over to port, the motor connections between the course computer and drive unit should be reversed. l If the rudder drives a few degrees to port, reverse the motor connections, and reverse the red and green wires of the rudder reference transducer. Reversal of the motor connections should be permanently made at one of the main terminal blocks and not by reversing the spade connector flying leads to the course computer.

All control units will emit a short beep tone to indicate that the computer is now active. L; Operating Sense The operating sense of the autopilot can be checked as follows:* Select Auto l Select + 10 which should move the rudder a few degrees to produce a turn to starboard. If this does not occur, correct operating sense can be restored as follows:* If the rudder immediately drives hard over to starboard, the red and green wires of the rudder reference transducer should be reversed in the connector unit.
