Fisher 3590 Valve Positioner Manual |top|

For current applications requiring similar functionality, Emerson typically recommends the Fisher DVC6200 series of digital valve controllers or to find a compatible replacement for an existing unit?

The complete Instruction Manual Form 5370 for Types 3590, S, and ST is hosted on Scribd .

Route the 4-20 mA control wires through the conduit opening. Connect the positive wire to the terminal and the negative wire to the terminal inside the terminal compartment.

The Fisher 3590 series is a family of heavy-duty, pneumatic valve positioners designed for precision stroke and angle positioning of rotary and sliding-stem control valves. The Fisher 3590 Positioner Manual serves as the definitive technical reference for installation, calibration, operation, and maintenance of this rugged, field-reversible instrument. fisher 3590 valve positioner manual

Pneumatic pressure up to full supply pressure (maximum 100 psig / 6.9 bar depending on the capsule configuration).

If you have questions about a specific ,g., sliding stem, rotary) The actuator size The specific issue you're facing.

Proper mechanical and pneumatic installation is critical to prevent hysteresis, slow response times, or premature mechanical wear. 1. Mechanical Mounting Connect the positive wire to the terminal and

Turn the internal zero adjustment screw until the valve stem begins to move from its dead-stop position (or hits the 0% travel mark on the scale).

Inspect the mechanical feedback linkage for play, wear, or loose pivot pins.

: Connect the instrument air supply to the SUP port and the output line to the actuator’s OUT1 port. Ensure the supply air is clean, dry, and meets the positioner’s pressure and flow requirements. Pneumatic pressure up to full supply pressure (maximum

Calibrating the Fisher 3590 establishes accurate zero and span reference points. Use an external current source (process calibrator) capable of generating a precise 4–20 mA signal.

Increase the input signal to the maximum value (e.g., 15 psig). Observe the valve travel scale. If the valve reaches full travel before 15 psig, or fails to reach full travel at 15 psig, you must adjust the span adjustment nut .

Route the 4–20 mA control loop wires through the conduit entrance located at the base of the positioner housing.
