Floating

The Floating component simplifies the control of 3-point valve actuators. This component has the following functions:

• analog input, working with PID regulators;

• 2 digital outputs for dedicated valve actuators (the Up and Down slots);

• analog output for dedicated actuators by voltage level (the Out slot, additional device required);

• reset function to automatically adjust physical and virtual valve position.

Slots

The Floating component has the following slots:

• Status: indicates the current status of the component (OK, Fault).

• Out: the voltage value controlled by the Floating component mechanism and transferred to the dedicated actuator;

• Up: the digital output for the rising function of a 3-point direct control valve actuator;

• Down: the digital output for the lowing function of a 3-point direct control valve actuator;

• In: the input value representing the required percentage of the actuator openness;

• Deadband: the value limit within which the output deviation from the required value can be ignored;

• Drive Time: the time which the actuator requires to change from the fully closed position to the fully open position (expressed in seconds);

• Reset: resets physical and virtual valve position.

Action

The Floating component has the following action:

• Reset: allows to periodically close the valve in order to synchronize the position of full closure.
