Travel Calibration
WARNING
During calibration the valve will move
full stroke. To avoid personal injury
and property damage caused by the
release of pressure or process fluid,
provide some temporary means of
control for the process.
Note
If optional limits switches are being
used, power must be applied to the
switch circuits throughout the
automatic or manual calibration
routine. Failure to power the switches
may result in incorrect switch
orientation.
To manually calibrate the instrument or automatically
calibrate the instrument without changing the tuning
values, the TRAVEL CALIBRATION routine is
available. To access this procedure from the home
screen, press the DOWN (
) arrow key two times and
then the RIGHT (
) arrow key once. From there follow
the prompts as illustrated in figure 3-3.
Note
If the valve is manually calibrated to
travel less than the physical travel
stops allow, manual tuning (page 3-7)
may be required to optimize the valve
response.
Automatic calibration will provide status information as
the procedure is running. Manual calibration will
require you to first adjust the input current to move the
valve and then to press the RIGHT (
) arrow key.
After manual calibration is complete, you will have the
choice to save the calibration or exit the procedure
without saving. If you exit without saving, the last
saved calibration data will be restored.
