Pressing the key will extinguish the red ”ALARM” LED, and send the track
heading to the ”SET HEADING” indication.
This indication should now be the same as that displayed on the navigation
receiver.
Note
Possible alarms and causes:
”
NAVDATA FAIL ”:
The Pilotstar D is not receiving any data from the navigation
receiver. Possible causes include broken or incorrectly connected
wiring, reversal of input to Pilotstar D Connection Unit, selection
of RS--232 rather than RS--422 at navigation receiver or output
port of Navigation receiver not enabled (refer to corresponding
GPS description).
” Nav Data Invalid ”:
The Pilotstar D is receiving data from the navigation receiver, but
the data is erroneous. Possible causes include poor signal at
receiver or no waypoint or route selected (refer to corresponding
GPS description).
19. Automatic adjustment of the PILOTSTAR D to the vessel’s speed.
Press the
Rud
key until ”SPEED ....” is displayed.
Test/Error diagnosis when different log sensor units are used:
-- Switch the log sensor to test mode (see handbook of log sensor).
The speed setting which is simulated via the test mode must now appear
in the speed SPEED display of the operator unit
After the test, leave the test mode!
-- If there is a combined navigation receiver (position-- and log sensor), it is
also possible to test the log transmission using the test mode (see handbook
of the navigation receiver). If the display is incorrect, see step #18.1.
-- Error diagnosis for the pulse log transmission (200 pulses per mile).
First the external wiring must be removed (B25.2.and 25.3).
When the connection terminals are temporarily bridged, the SPEED display
in the operator unit should show an increasing speed when the
PILOTSTAR D is working properly.
