Deflection Test (Rudder Or Azimuth Thruster Propulsion) - Simrad Robertson AP9 Mk3 Instruction Manual

Robertson AP9 Mk3 Autopilot
Deflection test (Rudder or azimuth thruster
propulsion)
To check the deflection of the rudder/thruster, set the main controls
as follows:
Parameter via INFO I:
Select AUTOPILOT and make a 90° course change. Verify that the
rudder/thruster stops at 20°, eventually adjust RV5/15 (Gain) for
proper rudder/thruster deflection.
If the Rudder/thruster response is of opposite direction, interchange the

HI/LO analogue signals to the Rudder /Thruster system.
Rudder Thruster combination
Normally a combination of rudder and thruster operation will consist
of an ON/OFF signal for the rudder, and an analogue ±10V signal for
the thruster. This may, however, vary from installation to installation
and the check-out of signal/performance is made according to signal
type (ON/OFF ±10 analogue) used.
As the parameters when using thruster is different from the
parameters used for rudder, a second set of parameters will be
enabled when switching the "TRUSTER SWITCH" to position
"THRUSTER". This position closes the connection between J4, 11-13
(Thruster Ident - GND). At the same time the ±10V analogue signal
from the control unit is enabled, and signal output is selected by the
INFO II loop "Thruster selection".
The analogue output will only appear when either THRUSTER or
Note !
THRUSTER & RUDDER is selected. Also note that an ON-OFF signal
may include the 2nd parameter set when Thruster Switch is activated. This
means that if the thruster interface signal is the ON-OFF type, "RUDDER
ONLY" function must be selected in the INFO II loop. Feedback is also
required.
