FAULT DETECTION AND CORRECTION IN VALVE ASSEMBLIES

A method of controlling a valve assembly includes calculating, by a controller of the valve assembly, one or more electrical signals to move a valve element of the valve assembly dependent on an actual and a desired position of the valve element. The method also includes sending, by the controller,...

Beschreibung
Zusammenfassung:	A method of controlling a valve assembly includes calculating, by a controller of the valve assembly, one or more electrical signals to move a valve element of the valve assembly dependent on an actual and a desired position of the valve element. The method also includes sending, by the controller, the one or more electrical signals to an electrical actuator of the valve assembly. The method further includes detecting a valve fault condition defined as the actual position of the valve element failing to match the desired position of the valve element after a configurable period has elapsed. When the valve fault condition is detected, the method includes substituting the data corresponding to the desired position of the valve element with pulses of waveform data which oscillate about a value corresponding to the desired position of the valve element until either of two predetermined conditions is met.
