3. Product Features

• Intelligent Microprocessor Control: Adopting core microprocessor technology, the device can automatically determine control parameters, greatly shortening equipment commissioning time and improving debugging efficiency.
• Fail-Safe and Fail-Lock Functions: In case of power or signal interruption, the positioner releases output pressure, and the actuator resets under spring force to drive the valve to a predefined safe position, ensuring system operational safety.
• Multi-Protocol Communication Capability: Supports HART, Profibus and FF communication protocols, enabling real-time data connection and remote interaction between on-site equipment and central control rooms.
• Simple On-Site Configuration: Equipped with an operation panel and LCD display, allowing convenient and intuitive on-site parameter adjustment and status viewing.
• Self-Diagnosis Function: Built-in self-diagnosis and alarm monitoring functions facilitate rapid fault location and support equipment predictive maintenance, reducing downtime risks.
• Temperature and Position Compensation: Adopting high-precision sensor technology to realize real-time temperature and position compensation, effectively eliminating environmental and mechanical errors and improving control accuracy.
• Modular Design: Optional functional modules are replaceable at any time without overall disassembly, providing high flexibility for equipment upgrade and maintenance.

4. Structure and Composition

• Core Component: Equipped with TEIP 11 I/P converter module as the core component, which undertakes the core function of converting electrical control signals into pneumatic output signals.
• CPU Processor: The built-in high-performance CPU is responsible for real-time processing of input setpoint signals and valve position feedback actual values, realizing closed-loop control logic.
• A/D and D/A Converters: Analog input signals are converted into digital signals via the A/D converter for algorithm calculation; the calculated digital signals are converted into analog signals through the D/A converter and transmitted to the I/P module.
• Position Sensor: Adopting a non-contact position sensor to convert valve mechanical displacement into electrical feedback signals, featuring ultra-low wear rate and long service life.
• Housing Structure: Made of high-strength aluminum alloy with IP65 (NEMA 4X) ingress protection, which effectively resists dust, water splash and electromagnetic interference in harsh industrial environments.
• Feedback Mechanism: Consists of a feedback shaft (the only moving part) and a position feedback rod, used for real-time detection and feedback of the actual operating position of the valve.

5. Application Fields

• Petrochemical Industry: Flow and pressure regulation control in full-process automated production systems.
• Power Industry: Steam system regulation and control for thermal power plants, nuclear power plants and other power facilities.
• Natural Gas Industry: Precise control of regulating valves for long-distance gas transmission pipelines and gas distribution systems.
• Other Process Industries: Suitable for accurate stroke control of various pneumatic linear and rotary actuators in chemical, metallurgical, pharmaceutical and other process industries.

6. Installation and Maintenance

6.1 Installation Steps

• Mechanical Connection: Mount the positioner on linear or rotary actuators through standard matching interfaces to ensure firm and stable installation.
• Pneumatic Connection: Connect the positioner’s air supply interface to the air source equipment, and connect the output interface to the cylinder of the pneumatic actuator with standard pipelines.
• Electrical Connection: Wire strictly in accordance with the official wiring diagram; connect terminals +11, -12, +31 and -32 as standard configuration.
• Feedback Rod Installation: Calibrate the installation angle of the position feedback rod to confirm that the connecting rod is correctly installed and flexibly linked without jamming.

6.2 Commissioning Steps

• Switch on the air supply and verify that the outlet pressure of the pressure reducer meets the parameter requirements on the actuator nameplate.
• Access the standard 4-20mA control input signal.
• Press and hold the MODE key while pressing the corresponding function key to enter the mode code setting interface.
• Run the automatic zero point and range calibration program for self-adjustment.
• Save and confirm all calibrated parameters to complete the commissioning process.

6.3 Maintenance Guidelines

• Regular Functional Inspection: Periodically check the operating status of the positioner to ensure stable operation and accurate output control.
• Filter Replacement: Inspect the air filter and filter element regularly, and replace worn or blocked filter elements in a timely manner to ensure clean air source input.
• Equipment Cleaning: Clean the equipment surface regularly according to the on-site dust and environmental conditions to avoid dust accumulation affecting heat dissipation and operation.
• Parameter Monitoring: Real-time monitor equipment operating parameters and operating status through the communication interface to grasp equipment operation conditions.
• Fault Troubleshooting: Utilize the built-in self-diagnosis function to detect potential faults and hidden dangers in advance, and carry out targeted maintenance.
