Open Stops Adjustments - GE BAKER HUGHES Masoneilan SVi 1000 Quick Start Manual

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).
