17 Appendix G – Procedure to Reset the Non-Volatile Memory to
Factory Settings
The ICoT PA positioner is a microprocessor controlled digital device. Its operation relies on data
that is stored in the positioner’s non-volatile memory. Calibration and configuration data that has
been established during the positioner’s setup and calibration is stored in this memory. Under
certain abnormal conditions this stored information can become corrupted. If this occurs it is
necessary to reset the memory and re-calibrate the positioner.
1.
Remove power from the positioner. This can be done by removing the plug-in style terminal strip.
2.
Press and hold the CAL button while replacing the terminal strip (returning power). The LCD will
show “Starting Up…”
for several seconds while holding down the CAL button.
3.
Continue to hold the CAL button until the LCD shows “Factory Default Initialization.” Scrolling on
one line and “No?” in the bottom right hand corner. When this appears release the CAL button
and use the down arrow to select “Yes” or press once more to select “All”. Then press the CAL
button to begin the factory default procedure.
a.
“Yes” option resets all non-volatile data to default with exception of the position calibration
data.
b.
“All” option resets all non-volatile memory contents including all factory and user calibration
data.
