The Fisher 3560 series (specifically the 3560G) is a legacy pneumatic valve positioner typically used with sliding-stem actuators. Because this is an older model, technical documentation is often found in consolidated Fisher manuals or archives from Emerson. Quick Reference Guide
If you are performing maintenance or calibration, follow these key steps based on standard Fisher pneumatic positioner practices: 1. Key Components
Beam: The central moving part that balances input and feedback.
Nozzle & Flapper: The assembly that converts beam movement into a pneumatic output signal.
Fulcrum Points: Critical calibrated points (labeled B and C in manuals) that should not be disturbed during routine maintenance. 2. Basic Calibration (Zero & Span)
Step 1: Set Supply Pressure – Ensure your air supply is clean and set according to the actuator's requirements (commonly 20–35 psig).
Step 2: Zero Adjustment – Apply the minimum input signal (e.g., 3 psig). Adjust the nozzle position until the valve stem just begins to move from its starting point.
Step 3: Span Adjustment – Apply the maximum input signal (e.g., 15 psig). If the valve travel is short, move the flapper assembly to a higher number on the beam. If it over-travels, move it toward a lower number.
Step 4: Iteration – Repeat steps 2 and 3 until both endpoints are accurate, as adjusting the span often shifts the zero. 3. Maintenance Tips Fisher 3560 Valve Positioner Manual PDF: A Comprehensive
Beam Alignment: If you have rebuilt the unit, the beam must be perpendicular to the nozzle. This is done by adjusting the follower assembly screw while at a mid-range signal. Visual Inspection:
Check for air leaks in the tubing and ensure the feedback linkage is tight and moving freely without "play".
Replacements: Many modern systems replace the 3560 with newer digital controllers like the Fisher DVC6200 Go to product viewer dialog for this item. for improved diagnostics and easier auto-calibration. Where to find the PDF manual

often replace them, the 3560 remains relevant for legacy systems. Core Function & Operation
The positioner acts as a comparator, receiving a pneumatic input signal from a controller and ensuring the valve stem reaches the exact required position.
Input/Output: It typically accepts a standard 3 to 15 psig pneumatic signal and provides a pneumatic output pressure to the actuator.
Feedback Loop: It uses a feedback mechanism (such as a travel pin or plate) to monitor the actual valve position and adjust the output until the error between the command and reality is zero.
