PRELIMINARY TEST.
After the installation of all mechanical and electrical components of the autopilot, a
first testing must be executed when still anchored or at the shipyard.
In order to obtain the best performance of the system, it is necessary to carry out at
least a trial at sea.
The first testing to be executed refers to the correct installation of the sensors and
must be carried out in the following sequence:
Rudder Feedback FB30, FB31
When the autopilot is in STANDBY mode, the graphic bar of the Control Unit
shows the reading of the sensor. By turning manually the wheel of the rudder,
verify that the angle shown is identical to the real position of the rudder.
If the indication of the rudder sign is opposite to the real one, switch off the
autopilot and invert the wiring connections which are linked to
TB5 FEEDBACK
connector, pin 3 and pin 4.
Rudder Indicator AR32, AR33, AR34
When the autopilot is in STANDBY mode, verify that the analogue rudder indicator
indicates exactly what is shown on the graphic bar of the Control Unit: in case the
analogue indicator is inverted, you must invert the two wires which are linked to
the Processor Box, pin 2 and pin 3 (
TB9
/
TB10
connector).
Fluxgate Compass FGX90/3, FGX90N
When the autopilot is in STANDBY mode, the large display shows the reading of
the electronic compass. Verify that there is no interference and the value
indicated by the main compass is not very different. In case of significant
difference, try to change the position of compass (if interfered) or by turning it on
its axle until the difference is cancelled.
Electrohydraulic Unit
If it is possible, when the vessel is still at the shipyard or still anchored, position
manually the rudder to the center. In AUTO mode, execute a course change of 10
/ 20 degree and check that the rudder moves in the correct direction and in an
intermediate position (the movement must be proportioned to the change).
In case the rudder moves in the opposite direction, invert the right and left
solenoids (power unit with solenoids) or invert the wires of the motor (reversing
power unit).
