Pitch Lock
By default, when the unit is turned on, the pitch angle of the ROV follows the present
position of the pitch joystick (the right joystick). Since the jo
ystick is “
spring return to
center
”, the body will also return to a 0 degree (horizontal) pitch when the operator’
s
thumb is off the joystick
.
If the pitch lock button is pressed, the operation of the pitch
joystick scrolls the pitch angle up or down and when the joystick is released, the pitch
angle remains at the last selected angle.
When the pitch lock mode is on, a target pitch
angle value is shown on the screen within (parentheses). This function is useful when
following a mooring line up or down on a constant angle. To release the pitch lock
back to center mode, simply press the pitch lock button again.
Reset
The Reset button is used to reset the thruster system or pitch system after a fault.
When the thrusters or pitch motor draw too much current, the ROV computer detects
this and shuts the system down in order to protect it. The most common cause of this
occurrence would be when the propeller is fowled. The system is re-activated after the
problem has been corrected by either pressing the reset button, or turning off/on the
entire ROV.
