Press Release Summary:
Logix(TM) 3200IQ and 500si series facilitate setup and calibration of diaphragm- or piston-operated valves. Explosion-proof Logix 3200IQ and intrinsically safe 500si series use piezo technology and inner-loop feedback to provide control with minimal air consumption in compact, modular designs. They also use HART communication protocol and feature LED indicators, Direct User Interface, jog calibrate function, and NAMUR and VDI/VDE mounting interfaces.
Original Press Release:
Flowserve Introduces the Logix 3200IQ and 500SI Series High-Performance Digital Positioners
State-of-the-art positioners offer quick setup and calibration
DALLAS - August 17, 2004 - Flowserve Corp., a global provider of fluid motion and control products and services, introduces the Logix(TM) 3200IQ and 500si series high-performance digital positioners.
Offering quick setup and calibration of either diaphragm- or piston-operated valves without the need for additional handheld devices, software or configuration/calibration tools, the Logix 3200IQ and 500si series are used in oil and gas production and refining, chemical processing, pulp and paper production, and other industries employing control valves.
The explosion-proof Logix 3200IQ and the intrinsically safe 500si series use state-of-the-art piezo technology and inner-loop feedback to provide superior performance, control, and reliability with minimal air consumption in compact, lightweight and modular designs.
The 500si series is available in two models - the 510si and the 520si. While the 510si serves the analog (4-20 mA) market, the 520si, like its sister, the 3200IQ, serves the "smart" HART® positioner market. By using the HART communication protocol, the Logix 520si and 3200IQ can provide wide-ranging data to a facility's control system (DCS or PLC) or to its maintenance database software.
"The Flowserve Logix 3200IQ and 500si series HART positioners enable our customers to realize all of the benefits of HART technology," says Wayne Naumann, marketing product manager, Flowserve. "These robust and reliable positioners are easy to configure and calibrate, and offer easily accessible diagnostic information, which makes it possible for our customers to minimize downtime and keep their plants up and running."
Features and Benefits
The Logix 3200IQ and 500si series offer a feature-rich set of benefits:
Commissioning is easily performed by simply setting a few switches and pressing the QUICK-CAL(TM) button. The Direct User Interface provides local access to positioner control without requiring multi-level menus, a handheld communicator or laptop computer.
Green, yellow and red local status LEDs, visible from a distance, indicate the positioner's current status without removing the cover.
LEDs provide instant information relating to internal diagnostic codes. These codes indicate positioner status and alarms to operators without the need for a handheld communicator or laptop computer.
A unique Direct User Interface enables the positioner to provide fast and easy configuration. Local configuration switches allow the user to set all basic parameters for positioner operation, such as output characteristic (e.g. equal percent, linear or custom), air action, signal direction, gain, tuning, etc. Calibration typically takes less than one minute.
Other important features of the 3200IQ and 500si series include:
A jog calibrate function allows the user to easily and quickly calibrate the positioner on all actuators without physical stroke stops.
Adapting the response of the positioner to a particular valve configuration is as simple as pressing a button. A built-in auto-tuning function, when enabled, quickly adjusts the response to match the valve and actuator. If the automatic tuning does not match the needs of the process, it can be modified in seconds by selecting a less aggressive auto-tune (gain) setting from the local user interface. Once set, the tuning is fixed until the next time an auto-tune is performed.
With Flowserve SoftTools(TM) software or a handheld communicator, a custom 21-point characterization curve can be generated that can be used to change the response of the positioner to meet the process requirements.
SoftTools allows the user to gather detailed diagnostic information regarding valve performance and positioner condition, in addition to the LED status codes.
Two-stage control provides faster response and tighter control.
A configuration lockout option in SoftTools permits users to perform automatic calibration procedures without modifying existing configuration and tuning settings.
NAMUR and VDI/VDE mounting interfaces provide direct standardized mounting to various linear or rotary actuators. Mounting kits are also available for non-NAMUR actuators.
