Glossary Padj (%) Valves often have significantly different response when filling versus exhausting. The proportional gain is adjusted by adding Padj to P when the valve is exhausting. Padj is normally less than P. Position Compensation The response of the valve is different when the valve is nearly closed Coefficient than when the valve is nearly open. The position compensation coefficient, which is a number between 0 and 9, allow the control algorithm to optimize the valve response. Damping Coefficient: The valve response may be made slower for some applications. A value of 0 gives no damping, and a value of 9 gives maximum damping of valve motion. Dead Zone(%): Quick Opening Relay, Pneumatic Safe Area Sig Hi Sig Lo Single Acting Split Range STOPS Stroke Tag When the valve position is within the setpoint +⁄- the dead zone, no additional position control is performed. This value is normally 0%, however for high friction valves (e.g. valves with graphite packing) a higher dead zone will help avoid limit cycling due to the stick⁄slip action of the valve. In these cases the dead zone chosen might be 0.2% to 1%. (see Characteristic) The component that amplifies the pneumatic control signals to provide a wide range of actuation pressure and to supply and vent at high flow rates for responsive control. The area of a plant where there never is an explosion hazard present, such as the control room or a wire marshalling rack area. In the SVI II AP configuration, the input current setting at which the valve is fully open (ATO) or fully closed (ATC) In the SVI II AP configuration, the input current setting at which the valve is fully closed (ATO) or fully open (ATC) The action of a position with a single pneumatic output for operation with a spring return actuator. (see double acting). A control configuration where a single control output is sent to two or more control valves. Each control valve positioner is calibrated to respond to a separate portion of the control signal. An example is a steam valve and a cooling water valve arranged to be both closed at 50% and the steam valve to open. The SVI II AP runs STOPS procedure to adjust the positioner to actual valve travel. First the output pressure is reduced to zero and the position is recorded. That will be the position corresponding to 0%. The output pressure is raised to its maximum based on supply pressure. The position is recorded and corresponds to 100%. The total range of valve travel. Often used as a verb to describe the process of moving the valve. The formal designator the control valve used in control loop documentation. G-6
Glossary Tight Shutoff (TS) ValVue® 2.4 Lite ValVue® 2.4 VDE⁄VDI 3845 VIEW DATA VIEW ERR A positioner property which is selected and adjusted when it is desired to prevent operation of the valve at or near the closed position. The positioner will cause all available actuator force to be applied to the valve seat at a position set point equal to or less than the TS adjustable parameter. A dead band is applied to prevent cycling in and out of this behavior. The Masoneilan software for calibration, and configuration that is provided with every SVI II AP. The full featured Masoneilan software for diagnostics, calibration, and configuration of SVI II AP. A Standard common in Europe for mounting positioners and accessories on rotary valve actuators. A mode of the positioner in which the configuration and calibration parameters may been examined, either remotely or with the local display. A mode of the positioner in which the error status or error messages may be examined G-7
