The Fisher 3560 series pneumatic valve positioners are foundational components in industrial control systems, designed to ensure precise valve stem positioning proportional to a pneumatic input signal. Accessing the Fisher 3560 Valve Positioner Manual PDF is essential for technicians to perform accurate installation, calibration, and long-term maintenance. Overview of the Fisher 3560 Positioner
The Fisher 3560 (often cited alongside similar legacy models like the 3582 or 3570) is a single-acting pneumatic positioner. It is typically used with diaphragm-actuated, sliding-stem control valve assemblies to modulate supply pressure and maintain a specific valve plug position. Key Technical Specifications
Understanding the performance limits of the 3560 series is critical for safe operation:
Input Signal: Standard ranges include 0.2 to 1.0 bar (3 to 15 psig) or 0.4 to 2.0 bar (6 to 30 psig).
Supply Pressure: Maximum pressures can reach up to 10.4 bar (150 psig) depending on the specific configuration, while the minimum is typically around 2.4 bar (35 psig).
Operating Medium: The unit requires clean, dry, non-corrosive air or natural gas.
Temperature Limits: Standard nitrile O-rings and diaphragms are rated for –34 to 71°C (–30 to 160°F). Installation and Mounting Procedures
The Fisher 3560 Valve Positioner Manual PDF provides two primary mounting methods: Fisher 3560 Valve Positioner Manual Pdf
Center-Bolt Mounting: Used when the actuator has tapped holes in the posts.
Clamp Mounting: Involves attaching the positioner using studs and hex nuts to the back of the housing.
During installation, it is vital to correctly set the feedback plate based on the actuator travel. For travels between 20 and 30 mm, the long portion of the plate's slot should be closest to the positioner. Calibration Steps for the 3560
Calibration ensures the valve responds accurately to control signals. General steps (similar to the Fisher 3582) include:
Zero Adjustment: Set the input signal to its minimum (e.g., 3 psig) and adjust the nozzle until the output gauge shows the valve is at its starting position.
Span Adjustment: Increase the input signal to the maximum (e.g., 15 psig). Adjust the flapper assembly or span adjustment screw until the valve reaches the full intended travel.
Linearity Check: Verify the 25%, 50%, and 75% travel points against the corresponding input signals (e.g., 6, 9, and 12 psig for a 3–15 psig range). Maintenance and Troubleshooting Common maintenance tasks involve:
The Fisher 3560 Go to product viewer dialog for this item. is a legacy pneumatic valve positioner commonly used to provide a valve position proportional to a 3 to 15 psi (0.2 to 1.0 bar) pneumatic input signal. While newer models like the Fisher 3660 Go to product viewer dialog for this item. or digital Go to product viewer dialog for this item.
often replace it in modern systems, many 3560 units remain in service or are available as reclaimed units for specific applications. Core Specifications Input Signal: Standard 3 to 15 psig pneumatic signal.
Output Signal: Pneumatic pressure as required by the actuator, typically up to 90 psi. Linearity: Approximately of output span.
Compatibility: Designed for sliding-stem valves with various Fisher actuators, including the 657 and 667 series. Installation Guide Mounting: Attach the connector arm to the valve stem.
Mount the positioner to the actuator yoke using the specified set of holes from the manufacturer's diagram (e.g., hole set #2 for a 657 size 40i actuator). Alignment: Move the actuator to the middle of its stroke. Align the rotary shaft arm parallel to the connector arm.
Insert the travel pin into the rotary shaft arm slot based on the rated valve travel. Connections: The Fisher 3560 is a mechanical marvel, but
Connect the air supply to the "Supply" port (typically 10% above max actuator requirement).
Connect the instrument signal (3-15 psi) to the "Instrument" port.
Connect the "Output" port to the actuator diaphragm or piston. Calibration Steps Fisher™ 3660 and 3661 Positioners
The manual contains detailed exploded view drawings. If you need to replace a cracked cover, a worn flapper, or a clogged nozzle, the PDF manual provides the part numbers and torque specifications. Guessing these values can destroy the internal relay.
The 3560 is often confused with a simple transducer. The manual clarifies:
The manual includes a cam selection chart:
Even experienced techs run into issues. Here are three scenarios where the Fisher 3560 Valve Positioner Manual PDF is the only solution.
Yes, but caution is advised. Emerson offers a 2-page "Bulletin 71.1:3560" for quick settings. However, for zero/span interaction or troubleshooting, the full 44-page manual is necessary.
This is the most common cry in the field. You inherit a skid with a 3560 installed. The stroke is incorrect, or the valve is hunting. You need the mounting instructions, the crossover chart, or the parts list.
Trying to guess the calibration settings on a 3560 is dangerous. An improperly set positioner leads to:
