Patent ID: 8342478

Claim:
A marine valve actuator assembly configurable to operate a plurality of different valves, the valve actuator assembly comprising: a main body, the main body including a movable output assembly, the movable output assembly alternatively coupleable to a valve and an output of a calibration test stand; a motor adapted to cause movement of the output assembly of the main body relative to the main body to open and close the valve when the output assembly is coupled to the valve for operation thereof and to apply a rotational force to the output of the calibration test stand during a calibration operation in which the output assembly is coupled to the output of the calibration test stand; a hand wheel assembly coupled to the main body, the hand wheel assembly adapted to cause movement of the output assembly relative to the main body to open and close the valve; a sensor coupled to the output assembly and operable to detect a force in response to a test load applied to the output assembly by the output of the calibration test stand during the calibration operation, or in response to a load applied during operation of the valve, and to generate a signal indicative of the force; a storage element adapted to store information indicative of the signal generated by the sensor to assist in calibrating the marine valve actuator assembly for subsequent operation of the marine valve actuator assembly with the output assembly coupled to the valve; and a controller communicatively coupled to the motor and the storage element and operable to control the motor based at least in part on the stored information stored by the storage element which includes information indicative of the signal generated by the sensor during the calibration operation.
