6.4 HALCYON 2000 COMPASS
6.4.1
Shows Heading and CAL Flashing
Symptom: Display flashes a Heading and CAL
Possible Causes:
(a) The memory in the Halcyon 2000 is empty or has
been corrupted. This may be due to a System Reset
being performed or the first time the compass has been
installed and not yet been calibrated. Perform a
calibration swing to restore normal operation.
(b) After a calibration swing the result is always FAIL.
There is a source of magnetic deviation near to the
Halcyon 2000 compass. Try re-positioning the compass
and perform the calibration.
6.4.2 Heading Shows Err
Possible Causes:
(a) The signal from the fluxgate sensor is too big or too
small. Try re-positioning the compass. If still showing Err
set NAVIGATE
? COMP CAL, CAL VAL 2 (RES CAL) to
1. This will reset the compass (see 4). All previous
calibrations will be lost.
6.4.3 Heading or COMP CAL Shows PHS
Possible Causes:
(a) The compass is in the middle of resetting, the display
should show heading and CAL flashing after 20 seconds.
A calibration swing will be required.
