The in. W.C. pressure value is entered into the no flow press field. For Triatek standard flow valves, this value is 0.6 in. W.C. If the pressure flow in the valve is invalid, a 0 CFM flow feedback signal is created.
The flow sw delay setting is used when a DP switch is connected to the valve that detects insufficient DP to produce a reliable CFM. The delay value is in seconds and is the time between when the DP switch detects a low flow and when the UVM zeros out the CFM feedback signal. This value is only relevant when the use DI as DP or use press sens as DP check box is selected.
The floating actuator is also used with the feedback sensor, where the valve position is determined by the feedback value and not the stroke time of the actuator. To enable this mode of operation, select the FB float act check box.
The float dead band is the dead band associated with the floating actuator position. This dead band value requests the CFM change before the actuator moves to new position.
