CALIBRATION

NOTICE
Each time the HTC Actuator is mounted onto the valve, the steps outline in HTC Actuator Calibration must be
performed to ensure proper operation and to determine optimum stroke of the actuator.
1 Ensure the HOT supply to the valve is isolated by closing the isolation valve on the HOT supply piping.
2
Ensure the manual tab on the actuator is in the up position and the actuator is not in the manual mode.
3 Ensure Dip Switch 7 is in the ON (MAN) position.
4
Switch Dip Switch 7 from the ON position to the OFF (AUTO) position and then back to the ON position.
• The Green and Red Status LED's should start blinking in an alternating pattern indicating calibration has
started. The actuator will move the valve stem up and down during the calibration. When the calibration is
completed the Green LED should be steady ON.
