Maintenance and Fault Finding

6.2.4Low Battery Alarm sounds.

The power level is low in the Hull Transmitter, NMEA Interface or Wind Transmitter. On any Digital Instrument enter Setup and Calibration mode (Page 18) and scroll through to the Health Chapter. Check the

signal levels of the Transmitters and Interface Box. The signal level should show a value of greater than 3 to ensure correct operation. Connect the Hull Transmitter or NMEA Interface to a 9 to 24V power source for 12 hours minimum to recharge the internal battery. Leave the Wind Transmitter in bright sunlight for 12 hours minimum to recharge its internal battery.

6.2.5Data is shown as dashes.

The information is not been transmitted to the instrument Displays. There may be lost communication between the Wind Transmitter or Hull Transmitter and the instrument Displays. On any Digital instrument enter Setup and Calibration mode (page 18) and scroll through to the Health Chapter. Check the signal levels of the Hull and Wind Transmitters. The signal level should show a value of greater than 3 to ensure correct operation.

6.2.6Compass Transducer rattles and/or splashes.

Good! The fluxgate compass is gimballed in a fluid filled container to ensure it is not affected by the boats movement in the water.

6.2.7Compass information displayed on the instrument system does not agree with the main steering compass.

Ensure that the main steering compass has been swung correctly and is showing correct information. Ensure that the instrument system has completed correctly the “Swing” procedure described on page 29. If there are still differences, look for magnetic objects (loud speakers, pumps and motors, etc.) close to the Transducer and try mounting the compass transducer in an alternative location. After changing position of nearby equipment or the Compass Transducer it will be necessary to re-swing the compass following the procedure on page 29.

6.2.8Boat Speed reads 0.

Information being transmitted from the Hull Transmitter is being received with a Zero value. Check the paddle wheel for fouling, clean it and make sure it turns easily.

6.2.9Wind Speed reads 0.

Information being transmitted from the Wind Transmitter is being received with a Zero value. If the anemometer cups at the top of the mast are turning and the Wind Speed reads 0 then there is a problem with your Wind Transmitter.

6.2.11 The Depth Alarm does not sound.

If the actual water depth is shallow and the alarm has not sounded it is most likely that the alarm is switched off. From any Digital instrument enter Setup and Calibration mode (page 18) and scroll through to the Depth Chapter. Ensure the Depth Alarm settings are correct.
