B. Other Fluxgate manufacturer, alignment.
When an interface unit is used to connect a Non Robertson
fluxgate to the AP9 MK3, the autopilot heading is adjusted by
the "FLUXGATE OFFSET" parameter.
C. RGC Interface Unit
When interfacing the RGC sine/cosine signals, make sure that
the Fluxgate parameter is set to 0 (zero) offset.
FOLLOW-UP Levers
Check that the FU/A scale parameter (Info loop II) is set for the
proper rudder deflection.
FU91/92
Check that the rudder response is correct both with regard to
direction of movement and deflection. Eventually reset the jumper
switches for autopilot configuration as shown on Fig. 3-16. Zero
setting may be adjusted by RV1.
Note that for the FU92, two identical boards are mounted side by
side.
Dual Station Configuration
Verify that the remote unit is working properly by observing that the
course display will show "STANDBY".
Push the helmsman button on the remote unit to take control.
Observe that the information display changes status and reads
HELMSMAN (or the mode selected by an external mode selector).
The main unit will now show STANDBY.
Verify that rudder commands are given and that the rudder moves
when making course change from the remote unit.
Mode selectors
When using external mode selector, either by a separate mode
selector or in combination with rudder/thruster change-over switch.
Verify that the proper autopilot mode is shown in the INFO display.
Check details as described in the Installation section. See Fig. 5-22.
