troubleshooting

no drive detected

fault description: The pilot attempted to move the rudder, but did not sense any change in rudder position, or, when the pilot attempted to move the rudder, it moved in the wrong direction.

check list:

1.Is the heavy duty power supply circuit breaker for the autopilot drive switched on?

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.

ξ Disconnect clutch from pilot electronics and test operation when connected directly to power supply.

ξ Check correct power is applied: 2A maximum

ξ Check that the dip switches in the ACP computer unit are set correctly for the rudder drive unit.

ξ Check correct power is applied:

RAM-T1-12V

12V, 15A

RAM-T1-12V

12V, 15A

RAM-T2-12V

12V, 25A

RAM-T2-24V

24V, 25A

RAM-T3-24V

24V, 25A

4.If the fault only occurs intermittently or under heavy loads, use power steer mode to move rudder while restricting movement by holding wheel. Fault only occurring under these conditions could be due to:

ξ Excessive motor current.

ξ Too much slack or backlash in drive or fixing to tiller, possibly due to air in hydraulic system.

no boat speed

fault description: The boat is stationary or moving very slowly (less than 1.5 knots) or the speed sensor is not working.

check list:

1.If boat speed for pilot comes from instrument system, check speed shown h1000 display or pilot display.

2.If boat speed connected directly to pilot, check connections.

3.Check boat speed sensor for correct operation.

no heading data

fault description: Compass data from the h1000 compass NMEA (via Fastnet2) or gyro input into the ACP has stopped or become unreliable.

check list:

1.Check heading display on pilot display unit.

2.Check connections from compass sensor to the h1000 Fastnet2.

3.Check gyro sensor and wiring if compass data is from an external device.

4.Check NMEA heading data and wiring if compass data is from an external device.
