Abstract
A control system for driving a motor that operates a valve comprises an open control switch operable to generate a first input signal in response to manual activation, a close control switch operable to generate a second input signal in response to manual activation, and a feather control switch operable to generate a third input signal in response to manual activation. The system further comprises a microcontroller operable to generate a feathered control signal in response to receiving a third signal and one of a first and second input signals substantially simultaneously, the feathered control signal operable to cause the drive motor to change the setting of the discharge valve at a feathered speed.
