Installation Guide

• Mount the positioner close to the actuator for stable pneumatic response.
• Use clean instrument air that meets DIN/ISO 8573-1 Class 3 quality.
• Connect electrical wiring to the 1/2-14 NPT port and air lines to the 1/4-18 NPT port.
• Confirm supply pressure stays within 1.4–6 bar (20–90 psi) before operation.
• Check the 4–20 mA input and analog feedback wiring for correct polarity.
• Set the tolerance band and dead band to match your valve control needs.
• Verify direct or reverse action based on your control signal direction.
• Test the fail-safe action after installation to confirm safe valve positioning.
