Patent number: 11280424Abstract: An actuator includes a drive device, and energy storage element and an actuator controller. The energy storage element is charged during operation of the actuator using power from an external power source. The drive device drives a valve member to a failsafe setpoint using energy from the energy storage element in the event of a power loss during operation of the actuator. The actuator controller provides a drive signal to the drive device indicating the valve member orientation (i.e. the failsafe setpoint) to which the drive device is to drive the valve member. The failsafe setpoint is determined based on the last fluid source that was controlled by the actuator of the fluid system prior to the power outage.Type: GrantFiled: June 3, 2019Date of Patent: March 22, 2022Assignee: Johnson Controls Tyco IP Holdings LLPInventors: Kevin A.
