10 Dockside Testing
10.1 Preparations
Start checking the following:
•
Familiarise yourself with the operating procedures by reading sections Operation,
Function and Setup.
•
Double check all wiring connections and dip switch settings prior to connecting
power to the system.
•
Make sure rudder angle limit [LIM] is set to 99
°
(OFF).
•
Ensure that the oil reservoir is 3/4 full and maintain that level throughout the test
procedure.
Warning! Do not activate any of the 3 Autopilot functions Compass, Nav or Wind at
dock as the rudder may go hard over, since the APC routine has not been carried out
yet. It will be done as explained in Sea Trials.
10.2 Dockside First Start
Run the procedure as described in First Start.
10.3 How to remove air from system
Select PWR ST function by pressing MODE until the page-arrow appears under PWR
ST.
To activate the Autopilot, press
SET .
Press and hold LEFT or RIGHT until the pumpset begin to run and the rudder moves.
If port rudder is given when you press starboard ( RIGHT) push-button, and vice versa,
ignore the reversal. It will be corrected automatically when doing the APC routine at
Sea Trials.
It may take time before the steering begins to move due to air in the system. Continue
to press and hold the push-button until the steering reaches its stops. Then reverse
direction with the opposite push-button. Repeat this procedure 10 times or more until
the system appears to move smoothly.
After 5 or 10 minutes of this purging, let the system rest so that entrained air can settle
out of the oil. After 5 minutes of rest, repeat the above procedure.
Air in the system may cause noisy pumpset operation. When the pumpset becomes
quieter and the steering moves smoothly and the linear drive responds instantly in both
directions, it may be assumed that most air is out of the system.
To check that all air is removed, select power steer function and try to turn the steering
wheel. In this function the steering wheel should be stiff. If you can turn the wheel a
certain amount with a increasing pressure as a result, there is still air in the system.
Continue to ventilate the system until the steering wheel is stiff before you proceed with
the sea trials.
Do not attempt to activate the Autopilot in other functions than power steer, until all air
is out of the system, as sloppy course holding will result. The very last air removal will
be done as the boat is tested underway.
