Open Stops Adjustments
In some valves the stem travel exceeds the nominal valve travel. The SVi1000 allows you to com-
pensate for this so that the valve position reads 100% at the nominal travel. The acceptable
range is between 60%-100% of possible mechanical travel.
To perform open stops adjustments:
1. Press the upper stop adjustment button for two to seven seconds, until green LED
2 illuminates, then release. Green LED 2 flashes.
2. Move the valve to the desired location via the Open Stop Adjustment Screw
(Figure 21).

3. Press the upper stop adjustment button for more than two seconds.
The green light goes off, the new stop is saved in the device and the unit is put into
Normal mode.
Press
Cancel to abort the process and the green LED 1 goes off, the device returns
to Normal mode and no changes occur.
