While many facilities are upgrading to digital alternatives like the Fisher DVC6200, the 3560 remains a critical component in many existing pneumatic loops.
The 3560 uses a cam-based feedback system. The manual provides the exact cam orientation for Rotary vs. Linear action. If you mount the cam backwards, the valve will fail "open" when you command "closed."
Apply the low-end input signal (e.g., 3 psig for a 3–15 psig range). Fisher 3560 Valve Positioner Manual Pdf
Low supply pressure; Plugged relay filter; Excessive packing friction on valve.
Maximum: 50 psig (3.4 bar) or 150 psig (10.3 bar) depending on the specific model capsule.

The valve stem continues to move until the feedback force perfectly balances the input signal force, locking the valve plug precisely in the commanded position. 3. Installation and Mounting Procedures
For Fisher 3560P electro-pneumatic models operating in explosive environments, ensure all intrinsic safety barriers and explosion-proof conduit seals are fully intact and compliant with local electrical codes (ATEX, IECEx, or FM).
