Fault - action
1. Wind: No reading [ --- ]
•
If inaccurate Wind data is received, check the connections (separate through deck
connection or below decks connection), are properly made.
•
Make sure the transducer is aligned correctly, (see C54, 6.4.4).
•
Measure with a voltmeter, at the screw terminal pin 1 and ground, and between pin
2 and ground.
•
If the voltmeter shows 1.5 to 4 V DC (minimum Wind speed 3 m/s) at both
measuring points, the transducer and the connections are OK.
•
If the voltmeter shows 0 or 5 V DC at both measuring points, the transducer or the
connections are defect. Contact you NX2 dealer with this information.
2. Speed and distance functions: No reading [ --- ]
•
C13 should be ON. See 6.1.3.
•
If you have a voltmeter available, you can check the condition of the transducer.
When measuring with voltmeter make sure everything is connected, that the power
is on and make sure the paddle wheel is rotating.
•
At the back of the instrument, measure between pin 4 and ground.
•
When not rotating, the value should be fixed at either about 0 or 5 V DC. When
rotating very slowly, by hand, the value should flip between 0 and 5 V DC. When
rotating faster, the value should average around 2.5 V DC.
Irregular values:
Check the speed damping (SEA), (see C11, 6.1.1).
3. Compass functions: No reading [ --- ]
•
C14 should be ON. See 6.1.4
7.2.3 Error
messages
The following error messages can appear on the display:
ERROR 2
Nexus Network is missing, check colour coded connections
ERROR 3
No Network data received within a given time.
ERROR 10
Range error caused by bad format, e.g. 430°.
ERROR 11

If other error messages than the above appears on the Wind Data instrument, contact
your NX2 dealer.
