Fisher 3560 Valve Positioner Manual Pdf ((link)) Guide

The Fisher 3560 series is a legacy line of pneumatic valve positioners typically used with pneumatic actuators to ensure accurate valve plug positioning. While newer models like the 3660 or DVC6200 have largely replaced them, documentation for the 3560 is still essential for maintaining older plant infrastructure.

Procedure:

  1. Disconnect the Positioner: Ensure the supply air is isolated and the loop is disconnected.
  2. Set the Cam: Based on your valve's flow characteristic (linear, equal %), select cam A (linear) or B (equal %). The manual shows cam installation direction.
  3. Apply 4 mA: Connect the signal generator. Apply 4.00 mA. Turn the Zero Screw (under the black cap) until the actuator just starts to move. Then back off slightly until the valve seats.
  4. Apply 20 mA: Increase to 20.00 mA. If the valve does not reach full travel, adjust the Span Screw (on the feedback arm) clockwise to increase travel.
  5. Iterate: Return to 4 mA. Recheck zero. Repeat steps 3 and 4 until both points are accurate ±1%.
  6. Lock Everything: Tighten the locking nuts on the range and zero screws. The manual includes a torque specification (6-8 in-lb).

The Fisher 3560 is a pneumatic valve positioner. In simple terms, it is a feedback control device that compares the desired position of a control valve (the setpoint from a controller) to the actual position of the valve stem. If there is a discrepancy, the positioner sends more or less pneumatic pressure to the actuator until the valve reaches the correct position. Disconnect the Positioner: Ensure the supply air is
