This module specifies the damper position in flow control modules and applications. This module accepts a mode as close, open, hold, control, box flow test, and failsoft and adjusts the output accordingly. Should control be requested and the flow is unreliable, it sets the damper position to a value proportional to the PD Max Position. Unreliable flow results in operation as a pressure dependent controller. Attempts to control near zero result in the damper being closed. The adjustable parameters provide a way for the user to configure the module to operate in the correct manner for control of any size damper.
This module provides EWMA diagnostic values calculated by the PID. Controllers have the ability to collect data about their inputs, outputs, and internally calculated variables. Inside the controller, the EWMA minimizes memory requirements, reduces communication traffic, and provides an easy way to analyze collected data. See EWMA Diagnostics in the Commissioning a System section for more information.
