Joystick Match and Rotary Knob Match (for the Configuration with Joystick)
If the system operates in Auto position control mode, the vector of thee total thrust produced by thrusters is continu-
ously displayed on the screen.
If the vessel position control is switched to the manual mode the vector of the total thrust is controlled by the operator
with the help of joystick.
The joystick tilt can be different from the one corresponding to the current vessel position so before the system is
switched to the manual control mode, the operator should synchronize the joystick position with the current thrust vector.
The Joystick Match indicator hints directions to tilt the joystick.
It helps to avoid an undesirable jump in the thruster control.
The Joystick Match indicator shows in which direction the joystick is to be tilted. This must be done to avoid undesir-
able jump in the thruster control and provide bumpless control transfer.
The same concerns the rotary knob in case the vessel heading control is switched from the automatic to manual mode.
The rotary knob match indicators see at the Figure 2.10.
NOTE!
If joystick behavior isn't consistent with your expectations, calibrate the
joystick with the Configuration menu, submenu Service menu, section
Joystick Calibration.
