The local user interface on the front of the device combines an LCD display and push buttons, and can be used in explosive atmospheres. From the front panel the user can execute the automatic adjustment (Auto Setup) program, check equipment status, and display various parameters.
Integration with device management systems can be done using EDDL, DTM, and PLUG-IN Valstaff.
The installed control valve diagnosis algorithm effectively applies data obtained from the embedded pressure sensors for measuring supply air pressure, output air pressure 1, output air pressure 2, and nozzle back pressure.
Easy to use
Auto setup: The auto-setup function is a fully-automatic configuration program which specifies the actuator and adjusts the zero and span of the valve. The program can be turned on simply from an external switch so that adjustments to the valve can be performed quickly and safely in hazardous areas.
High reliability
Positive seating: The positive seating function completely shuts off the valve if the input signal becomes lower than previously set. This in turn enhances the full shut-off capabilities of the valves.
Self-diagnostic: The self-diagnostic function provides with the ability to check the status of the positioner at any time and to alert in case of failure.
