Stroke Calibration
Calibrate the position feedback sensor in the unit. The process requires that the valve stroke from
full open to full closed. Because the valve will change position during this process you must confirm
that you want to proceed. You will then be prompted for the valve type; linear or rotary. If the air
supply varies by more than 1 psi during the calibration, the test may abort. Hence, a regulator may be
required if the air supply is not stable. The unit will then complete the calibration process by stroking
the valve open and closed over one to five minutes. Upon successful completion of the process, the
system will momentarily flash the message “Calibration Successful”.
WARNING
: Notify personnel working nearby that the valve will stoke during this procedure; otherwise,
serious injury may occur.
Explanation: Saturation level = Percentage of supply pressure used to saturate the actuator at both
extents of travel.
