(2) Check installation, look for any slack or loose fixings
in the drive system or the rudder reference as the helm is
moved.
(3) Move the helm. Does the rudder indicator work, if
not, check installation of rudder reference unit as detailed
above.
(4) Select "Power Steer" mode. If drive system includes
a clutch or solenoid valve, engage the pilot and check the
operation of the clutch or solenoid valve. It should not be
possible to move the helm with the autopilot engaged. If
clutch fails to operate:
- Disconnect clutch from autopilot electronics and
test operation when connected directly to power
supply.
- Check correct Ampere rating is applied:
All pilots - selected voltage at up to 2 Amps.
(5) With autopilot engaged in "Power Steer" mode, use
10 deg. and 1 deg, Port and Starboard keys to move
rudder. If the motor fails to run:
- Disconnect motor from autopilot electronics and
test operation when connected directly to power
supply.
- Check correct Ampere rating is applied:
ACP1 pilots - 12V or 24V up to 25 Amps.
ACP2 pilots - 12V or 24V at up to 40 Amps.
(6) If the fault occurs intermittently or under heavy loads,
use power steer mode to move rudder while restricting
movement by holding wheel. A fault occurring under
these conditions could be due to:
- Excessive motor current.
- Too much slack or backlash in drive or fixing to
tiller, possibly due to air in Hydraulic system.
- Software allows 3-speed control of drive motor for
smoother rudder movement. The software increases
the speed of drive motor if the drive motor stalls at
slower speeds.
