5. For On/Off operation using dual­input dry contact:
a. Close the contact to create a short between pins COMMON and CLOSE. If Span is currently uncalibrated, valve
ball/disk will not move at this time.
b. Close the contact to create a short between pins COMMON and OPEN. If Span is currently uncalibrated, valve
ball/disk will not move at this time.
c. Close the contact to create a short between pins COMMON and CLOSE – valve ball/disk will move to its fully
opened position, followed after a delay by moving to its closed position.
6. For On/Off operation using single dry contact:
a. Open the contact to create an open circuit between pins COMMON and OPEN. If Span is currently uncalibrated,
valve ball/disk will not move at this time.
b. Close the contact to create a short between pins COMMON and OPEN. If Span is currently uncalibrated, valve
ball/disk will not move at this time.
c. Open the contact to create an open circuit between pins COMMON and OPEN – valve plug will move to its fully
opened position, followed after a delay by moving to its closed position.
7. The unit is now calibrated.
Analog Input Calibration
For valves using 4-20 mA as a control source, several options are available to customize control of the actuator. Use a
4-20 mA signal generator to provide the desired signal. It is possible to calibrate the 4-20 mA signal in reverse acting or
split-ranging with the method below with at least 4 mA of signal difference between the close and open values. The
example shows a valve being changed from normal to reverse acting during the calibration process.
1. With the Control Method set to 4-20 Positioning or 4-20 mA Level, enter the Calibration screen and the 4-20 mA
Signal Calibration window will be visible.
2. Click the CALIBRATE CLOSE & OPEN VALUES button. A separate window will open to guide through the process.
3. Set the 4-20 mA signal to the desired value for when the valve is to be closed.
4. Enter this value into the Calibrated mA Signal text box and press Next.
