5. A method for controlling a hybrid winch, the method comprising:
-
determining at a winch controller processor if generator power failed; exiting the program if the generator power has not failed; and measuring tension on an anchor cable attached to the winch and an anchor and instructions to adjust torque of the winch pulling the anchor cable in a controlled release, when the generator power has failed. - View Dependent Claims (6, 7)
