Special Instructions for “Safe Use” and Installations in Hazardous
Locations
WARNING
To avoid static discharge from the enclosure, do not rub or clean the enclosure with solvents. To do so could result in an
explosion. Clean with a mild detergent and water only.
The enclosure is nonconducting and may generate an ignitioncapable level of electrostatic charges under certain extreme
conditions. The user should ensure that the equipment is not installed in a location where it may be subjected to external
conditions (such as highpressure steam) which might cause a buildup of electrostatic charges on nonconducting surfaces.
Additionally, cleaning of the equipment shall only be done with a damp cloth.
To avoid damage to the enclosure, when screws are fully tightened into blind holes in enclosure walls, with no washer
fitted, at least one full thread shall remain free at the base of the hole.
Actuator Mounting
The following procedure describes how to mount an easy-Drive 200L actuator.
The actuator is shipped with the stem in the ideal coupling position; 6% off the lower actuator stop.
Note
Do not stroke the actuator prior to coupling the unit to the valve.
To reposition the actuator to the ideal coupling position calibrate the actuator as valve type “Stop-to-Stop”. Ensure the actuator is
able to travel making contact with its internal stops. Once calibration is complete command the valve to 6% open.
User designed and manufactured Mounting Kit and Stem Coupler will be needed to complete this procedure.
WARNING
To avoid personal injury or property damage, keep hands and tools out of the actuator stem travel path when moving the
actuator stem in the following steps.

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 420 mA:
a. Apply a 4 mA signal between pins 4-20 mA - and 4-20 mA +. If Span is currently uncalibrated, valve plug will not
move at this time.
b. Apply a 20 mA signal between pins 4-20 mA - and 4-20 mA +. If Span is currently uncalibrated, valve plug will not
move at this time.
c. Apply a 4 mA signal between pins 4-20 mA - and 4-20 mA + – valve plug will move to the upper stop, immediately
followed by moving to the lower, 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.
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
plug 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
plug will not move at this time.
c. Close the contact to create a short between pins COMMON and CLOSE – valve plug will move to the upper, open
position and then to the lower, closed position.

Instruction Manual
D104331X012

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 plug 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
plug 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 the
upper, open position and then to the lower, 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.
Figure 14. Fisher easy-Drive Configuration Software
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.

Maintenance
The frequency of inspection and maintenance depends on the severity of the service conditions.
WARNING
Avoid personal injury from sudden release of process pressure or bursting of parts. Before performing any maintenance
operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from both sides of the valve.
D Back plug away from seat to relieve spring compression.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
WARNING
