Span Calibration
It will be necessary to perform a span calibration. A span calibration is accomplished by the following method:
Note
If the actuator is equipped with a RPU-100, the RPU-100 must be disabled via the Disable switch prior to powering off the actuator.
1. Ensure the process and valve are in a safe state – the valve may move during this operation.
2. Press the “CALIBRATE SPAN” button to initiate the span calibration. The software will show a progress bar during
the calibration and display “Valve Span Calibrated” when complete.
Note
Should actual travel not equal the expected travel you will receive a span calibration failure alert. See figure 13. Ensure valve type is
selected correctly. It may be necessary to re-couple the valve actuator assembly.
Figure 13. Fisher easy-Drive Configuration Software
Span Calibration without the use of Modbus
1. Turn power to the actuator off.
2. Wait for 10 seconds to ensure all circuits have discharged.
3. Return power to the actuator and use the appropriate calibration method for your control signal. Calibration
sequence must be done within 15 seconds of power being switched on.
4. For positioning operation using direct acting 4-20 mA:
a. Apply a fully closed signal between pins 4-20 mA - and 4-20 mA +. If Span is currently uncalibrated, valve ball/disk
will not move at this time.
b. Apply a fully open signal between pins 4-20 mA - and 4-20 mA +. If Span is currently uncalibrated, valve ball/disk
will not move at this time.
c. Apply a fully closed signal between pins 4-20 mA - and 4-20 mA + – valve ball/disk will move its fully opened
position, followed by moving to its closed position.
d. If calibration of the analog input is desired to improve positional accuracy, an optional operation is listed in the
next section titled Analog Input Calibration.

Instruction Manual
D104742X012

5. For On/Off operation using dualinput 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.

5. Set the 4-20 mA signal to the desired value for when the valve is to be open.
6. Enter this value into the Commanded mA Signal text box and press Next.
Figure 15. Fisher easy-Drive Configuration Software
7. If the Close and Open values are as expected, press Confirm to accept these values. If not, press Cancel to restart
the process.
Note
The value of the 4-20 mA signal must have at least 4 mA difference between the close and open signals. A differential less than
that amount will cause the actuator to reject the calibration and use the previous values.
Should the entered values vary more than 10% from the expected 4-20 mA values; the actuator will accept the calibration and a
Notification displaying “Questionable Analog Calibration” will result.
