Abstract
A system for exercising a valve may comprise a valve exercising apparatus having inoperative and operative conditions, a transitional event when the apparatus transitions from the inoperative to the operative condition. The exercising apparatus may comprise a valve exercising motor for connecting to the valve and a controller assembly for controlling operation of the motor. The controller assembly may operate in a manual control mode and an automated control mode, with the manual control mode being characterized by operation of elements of the exercising apparatus being initiated by manual input from the operator, and the automated control mode being characterized by operation of elements of the exercising apparatus being initiated by the controller assembly. The controller assembly may be configured to operate the apparatus in a startup condition at the occurrence of the transitional event, and the startup condition may correspond to the manual control mode.
