Note:
Ensure that you hold the compass with the cable protruding downwards.
Step 5 - Rudder Reference
1. Check that the rudder offset value is set to zero. (To adjust, use the Dealer Calibration screens.)
2. Move the rudder reference into the central position.
3. Check that the rudder bar on the display is in the central position.
4. Move the rudder reference to the left and check that the rudder position bar on the display moves to the left.
5. Move the rudder reference to the right and check that the rudder position bar on the display moves to the right.
Note:
If the rudder bar display moves the wrong way, turn off the power, reverse the red and green wires connected to the
RUDDER inputs on the Course Computer, switch on the power and re-check.
Step 6 - Clutch (Auto)
1. Ensure that the rudder reference is in the central position.
2. Press AUTO
3. Measure voltage at clutch terminals (12 V nominal), then proceed to Step 7.
Step 7- Clutch (Standby)
1. Press STANDBY
2. Measure voltage at clutch terminals. If the voltage is 0 V, proceed to Step 8
Step 8- H-Bridge
1. Press AUTO.
2. Press +10 twice, the motor should spin.
3. Press STANDBY, the motor should stop.
4. Press AUTO
5. Press -10 twice, the motor should spin in the opposite direction
6. Measure HD-PWR whilst the motor is running (Check this against the table in Step 1).
Step 9 - NMEA
RECEIVE
1. Enter a new waypoint into the C/E Series unit.
2. Perform a "Goto Waypoint" command on the C/E Series unit.
3. Verify that the waypoint information has been sent to the Course Computer by viewing the XTE, DTW and BTW data
pages on the Control Unit.
TRANSMIT
Check that the heading displayed on the C/E Series unit matches that of the Autopilot.
Step 10 - EEPROM Test
This test checks that the calibration settings are being stored correctly.
1. Using the calibration screens, change the Drive Type to a different value.
2. Save the setting and exit calibration.
3. Remove and re-instate power to the Course Computer.
4. Verify that the new drive type is still active.
