• Air to Open Actuator 1. Insert the alignment pin in the hole marked A 2. The feedback arm rotates counterclockwise, from A to B as air pressure to the casing g or lower cylinder y increases. • Air to Close Actuator 1. Insert the alignment pin in the hole marked B 2. The feedback arm rotates clockwise from B to A as air pressure to the casing or upper cylinder increases. increases

4 – 20mA Source

Auto Calibration • Select to Auto travel calibration, the control valve start to stroke from 0% to 100% open automatically. • Wait until the calibration is completed. completed Manual Calibration • Select To Manual calibration, its allows you to determine 0% to 100% calibration point. • Refer to Hart Communicator for some adjustment for tuning and travel calibration.

7. Control Valve Limit Switch

• Limit switch for “open position” when control valve is in fully open open, the contact is close for fully open feedback.

• Limit switch for “close position“ when control valve is in fully close close, the contact is open for fully close feedback.
