5.2.2 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, 5.4.4).
•
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 Nexus dealer with
this information.
2. Speed and distance functions: No reading [ --- ]
•
C13 should be ON. See 5.1.3.
•
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, 5.1.1).
3. Compass functions: No reading [ --- ]
•
C14 should be ON. See 5.1.4
