Log In Sign Up. Jorge Gaitan. The Logix si family. Modularity is our strength. Calibration typically takes less than one minute. The jog calibrate function allows the user to easily and quickly calibrate the Jog Calibrate positioner on all actuators without physical stroke stops.
The Logix positioner has a built in auto-tuning function that, when enabled, quickly adjusts the response to Auto Tune match the valve and actuator. State-of-the-art piezo technology combined with inner-loop feedback produces Low Air Consumption high-performance control with minimal air consumption. SoftTools allows the user to gather detailed diagnostic information regarding Diagnostics valve performance and positioner condition, in addition to the LED status codes.
As with all positioners in the Logix si family, status. Interchangeable components such as feedback to produce an improved dynamic behavior. The complete circuit board, piezo-drivers, etc.
Different upgrade or repair. Optional 4—20 mA analog feedback circuit and gain values allow the best setup for each individual actuator size. This two-stage control provides for a more responsive and with an analog 4—20 mA input signal. The positioner consists of tighter control than is possible with a single-stage control algorithm. The module with optional analog feedback and direct local user interface change of pressure and volume of the air in the actuator causes the switches; 2 the piezo-valve-based electro-pneumatic converter valve to stroke.
The tion becomes smaller and the output to the piezo is decreased. The decrease, which slows the actuator movement as it approaches the control algorithm in the processor performs dual gain calculations new command position.
The pilot valve position in the pneu- the valve in a constant position. They combine state-of-the-art piezo valve technology as high-performance digital communications. With its versatile with inner-loop feedback that provides high-performance control mounting options, the Logix si digital positioner offers a cost- with minimal air consumption.
Highly any manufacturer. The The basic positioner operation is best understood by referring to change of pressure and volume of the air in the actuator causes Figure 5. The complete control circuit is powered by the two-wire, the valve to stroke. As the valve approaches the desired position, 4—20 mA command signal. The the valve in a constant position. SoftTools Suite is a complete tion. Additionally, the user can access customized digital positioner addressed through the software. Diagnostic tests and functions formally valve stem position, control signal, and other important process available only in strap-on diagnostic testers are now part of the metrics.
Multiple instances of the software can be run simultane- functionality. The software retains the traditional signature and ously, addressing unique positioners. The output of each control point is independent, allowing the user to create a custom curve with very high resolution.
This customized curve can be saved in the memory of the Flowserve Logix si, and either activated or overridden with a simple on-board selec- tor switch.
Tuning Unlike other positioners that offer only one gain setting, the Logix si positioner provides dual-gain tuning. This allows the user to tune the positioner to make large step changes with minimal overshoot, while achieving the resolution to respond to very Figure 8: Manual Tuning with User Interface small step changes.
The Logix si posi- tioner not only provides several preset gain settings, it also allows the user to develop custom settings for a wide range of actuator sizes and types. The Auto Tune procedure cycles the actuator Figure 8 to produce a measured response and selects those gain values that provide appropriate actuator per- formance. Signatures can be saved and cataloged and later retrieved for comparison Figure 10 with a more recent signature.
SoftTools software allows a user to easily overlay valve signatures and compare current performance with past performance over a par- ticular time period. This allows the user to determine if degradation has occurred over time on critical valves.
It also allows the user to compare historical data and determine if a valve needs to be pulled for maintenance. Internal sensors allow the user to test the response and health of the valve at any time. Positioner Performance Static performance and accuracy measures such as hysteresis, deadband, linearity, and repeatability can be obtained with the Logix si positioner: These values can be graphically depicted, stored and later retrieved for comparative analysis Figure This innovative, robust pack- feedback signal proportional to the valve age provides the following features: position throughout the complete stroke length.
This eliminates exposed linkages while allowing easy access to mounting screws from the exterior for fast and easy service. The Logix si digital positioner also lends Plug Control Valve. Brackets are available for the most popular brands and sizes of actuator. Valve Assembly. When properly selected, this Flowserve product is designed to perform its intended function safely during its useful life.
