| No indication on any display. |
Indicates lack of power on the Ockam bus
- Check system power .
See Power Troubleshooting.
- Check the bus. See Ockam Bus Troubleshooting.
|
| Strange display. |
See Display Troubleshooting. |
| LOG or TIME resets on power up or engine start. |
Dead backup battery. Return CPU for service when
convenient. |
| Boatspeed not zero when it should be. |
- (Several Knots) Usually caused by the AC power
to the battery charger. Try disconnecting the boat from shore
power.
- (Small number or Intermittent) Caused by
current or vibration transmitted through the hull to the paddle.
NOTE:
because they have no bearings to unstuck, ultrasonic boatspeed sensors
will typically show a few tenths of a knot at the dock. |
| Apparent Wind Speed not zero when it should be. |
- (Several Knots) Usually caused by the AC power
to the battery charger. Try disconnecting the boat from shore power.
- Caused by mast vibration.
- Apparent wind speed modified by roll rate. See
discussion in Section 4, Option 8.
|
| Bad Wind Direction. |
- No True Wind Speed. Since true wind is a vector
solution, when true wind speed is zero, True Wind Direction has no
meaning and is set equal to Heading.
- Check True Wind Angle, True Wind Speed and
Heading for proper values.
|
| Bad True Wind Angle. |
- No True Wind Speed. Since True Wind is a vector
solution, when True Wind Speed is zero, True Wind Angle has no meaning,
and is set to 0.
- Check Apparent Wind Angle, Apparent Wind Speed
and Boatspeed for proper values.
|
| Bad Apparent Wind Angle. |
- Apparent wind angle modified by roll rate. See
Setting Mast Height.
- Bad masthead sensoror or connection between
masthead and interface. Check for TEST Errors 33, 34 and 35.
- Loose masthead bracket.
|
| Bad Heading. |
- No power to heading sensor. Most heading
sensors require a separate power supply. Check that
the heading sensor is receiving power.
- Some magnetic item has gotten near the sensor.
- Sensor needs compensation.
