Auxiliary Terminal Calibration

Note
This calibration method can be used when there is no Class­2 master or other configuration software available. Prior to initiating
calibration ensure that the device has sufficient power and air supply.
WARNING
Changes to the instrument setup may cause changes in the output pressure or valve travel. Depending on the application,
these changes may upset process control, which may result in personal injury or property damage.
WARNING
During calibration the valve will move full stroke. To avoid personal injury and property damage caused by the release of
process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the
process fluid.
Travel calibration and auto tuning can be accomplished by shorting the auxiliary terminal connections, shown in
figure 4‐2, between 3 to 10 seconds. You can abort the procedure by shorting the auxiliary terminals for 1 second.
Pressure range will also be captured during this procedure.

Note
Calibration time varies depending on the type and size of the actuator. For a Fisher 667 size 30 actuator typical calibration time is
approximately 4-5 minutes.
