Thruster Trim
The right and left thrusters can be trimmed to ensure the ROV drives straight when the
joystick is full forward. Small variances in the ROV can pull it slowly to one side. To adjust
the thruster trim, place the ROV in an open body of water with no wave action or current.
Descend the ROV slightly below the water line so it is fully submerged but still visible by eye.
Throttle the thrusters full forward and observe the path it takes. Do not attempt to trim the
thrusters with the auto-heading or auto-depth engaged. (See Page 24 for more information
on auto-heading and auto-depth)
To calibrate the Thruster Trim: Press the MENU button, scroll down with the right joystick to
‘
CA
LIBRATE’. Press the ‘2’ button to enter this menu. Use the right joystick to scroll down to
Trim Right or Trim Left.
Press ‘2’ to
trim the thruster 1% each time you select an option.
Pitch Trim
The pitch can be trimmed to hold any angle without using the pitch joystick. This allows an
operator to fine tune the “home” position of the tilt of the ROV to slightly up, perfectly
horizontal, or slightly down, depending on the operator’s preference. Do not attempt to trim
the pitch with the auto-heading or auto-depth engaged. (See Page 24 for more information
on auto-heading and auto-depth)
To calibrate the Pitch Trim: Press the MENU button, scroll down with the right joystick to
‘
CALIBRATE
’. Press the ‘2’ button to enter this menu. Use the right joystick to scroll
down to
Trim Pitch Up or Dn. This will trim the ‘home’ position of the pitch 1 degree each time you
select an option
using the ‘2’ button
.
Gain /Scroll Buttons
The gain control can be adjusted on the hand controller to increase or decrease the speed of
the ROV. For example, in situations where there is no current and small precise movements
are necessary, reducing the gain may be beneficial. The Gain up/down buttons are located at
the front
inner
right hand side of the controller. The up button increases the ROV gain and
the down button decreases the ROV gain. When the gain buttons are used, your speed will
appear in the top center of the screen for 5 seconds. Once it disappears the gain has been
set. By default the ROV gain starts at 8 but can be increased up to 10 or decreased to 4. Gain
is the overall power sent to the thrusters, so an 8 is 80%, 5 is 50% and so on.
These arrows also function as scrolling buttons that activate immediately after various
other buttons are pressed. The user has 5 seconds to make adjustments to these settings
before the arrows return to gain adjust. There is always a scrolling number shown on
screen to allow the user proper feedback.
These gain control up/down button will also adjust these functions when they are first
activated.
