发明名称 SYSTEMS AND METHODS FOR HANDLING OVERCURRENT AND UNDERCURRENT CONDITIONS IN SUBSEA CONTROL SUBSYSTEM COMPONENTS
摘要 Systems, methods, and computer readable media for handling overcurrent and undercurrent conditions in subsea control subsystem components include determining, by a current sensor operatively coupled to a solenoid valve 64, that an input current to a solenoid 66 is greater or lower than a predetermined threshold value, de-energizing, by a processor operatively coupled to the current sensor, the solenoid for a first period of time, re-energizing the solenoid at least three times after the first period of time, determining, by the current sensor, that during each of the at least three times the input current to the solenoid is greater or lower than the predetermined threshold value, and de-energizing the solenoid and transmitting a control signal to a control unit.
