Use clean, dry, oil-free instrument air conforming to ISA Standard 7.0.01.

While specifically for the 3560, you may need to look for or similar documentation from Emerson Process Management.

Before mounting, verify that the positioner model matches the action of your actuator (Direct Acting vs. Reverse Acting). Inspect the feedback linkages for any signs of bending or thread damage during transit. Step-by-Step Mounting

"The problem with you kids

The Fisher 3560 Pneumatic Valve Positioner is a widely recognized component in process control industries, known for its rugged design and precise control of control valve actuators. As a pneumatic positioner, it accepts a standard pneumatic input signal (typically 3-15 psi) and uses that to accurately position a control valve plug, ensuring high-performance control in demanding applications.

The Fisher 3560 pneumatic valve positioner is a durable, high-performance instrument used across industrial processing plants worldwide. Designed by Emerson, this pneumatic positioner ensures accurate control valve alignment by adjusting the output pressure to an actuator. This matches the valve stem position to the input signal from a control system.

Regular maintenance ensures the longevity of the 3560 positioner. The instruction manual provides a detailed exploded view of the unit to help identify key parts like bellows, O-rings, and feedback springs. Fisher 3560 Valve Positioner Manual Pdf
