I did a calibration on this masoneilan SVI 2 AP positioner and after the calibration I got a message “stops fail”. I’ve been looking for this fault code all over the web, can’t seem to find anything. The valve seems to be operational. Has anyone seen this fault and had a remedy for it? Picture of the fault attached.

 

The Calibration menu shown in Figure 35 provides access to all the calibration functions for the SVI II AP. If a change is made in the Air-To-Open/Air-To-Close configuration option or if you move the SVI II AP to a different valve or make any change to the valve position linkage, you must run the find STOPS calibration again. -Courtesy Masoneilan

 

Did you make stops before calibration?
