2.4.5 Joystick Gain
The Joystick Gain makes the joystick more or less sensitive. The setting can be changed by entering a number between
0 and 100%. The Joystick Gain setting is used for as well Manual as Auto joystick mode.
At a gain of 1% the joystick has minimal effect. Pushing the joystick lever to the outer edge will only slightly increase
engine thrust. At a gain of 100% pushing the joystick lever to outer position will increase engine thrust majorly.
For in harbor use the percentage can best be set at 30% or lower. The Gain option can be set via the MAP screen
(Joystick Gain Setting on page 36).
To set Gain option perform the following actions:
1. Click on the JSM GAIN percentage value in at the lower left of the screen.
2. Enter a new value between 0 and 100, for example for use in harbor click on "3" and "0" to set to "30".
3. Click OK to confirm.
2.4.6 Wind Compensation
The Wind Compensation is off by default. This to ensure the thrusters will not immediately engage after the DP system
takes over the control to counteract the wind forces. The Wind Compensation is turned off automatically when changing
to another mode. For example turning wind compensation on in auto position mode, it will be turned off when changed to
joystick manual mode.
To turn on Wind Compensation perform the following actions:
1. Locate Wind Compensation area in lower left area of MAP Screen.
2. Select check box to turn Wind Compensation.
3. Press OK on the confirmation dialog.
4. Set percentage value to 100% (normal).
5. Optionally set percentage value lower (50%), if the vessel is over responding to the wind.
Note The amount of Wind Compensation is determined by the percentage set: 0% is no compensation,
100% is normal use. Before using the Wind Compensation on / off button on the operator panel check that
percentage value is set up properly.
Lowering the Wind Compensation will also lower the thrust. If the vessel does require this thrust to stay in position, the
regulator will increase the integration factors. See Force Calculation on page 19 for more information on how thruster
force is calculated.
2.4.7 Current Compensation
When in auto position mode, current compensation is turned on by default. When in joystick manual mode, it is turned
off automatically. When the system is in auto position mode it continuously calculates and updates the current speed
and direction. When system is in joystick manual or auto mode it remembers the last values used in Auto position mode.
When the system is set to Auto Position mode again, it continues to use the previously calculated and remembered
values.
