b. Checking Valspeq specs for required full travel.
c. Calculating the stop adjustment %:
Open Stops Adjustment (OSA) is defined as the ratio between required and full
travel:
OSA = (required travel)*100/(full mechanical travel).
For example: (3.8" required travel)*100/(4.8" full mechanical travel) = 79 % stop
adjustment.
A sample procedure is:
1. Click the
Find Stops tab and entering 79% in Open Stop Adjustment field.
2. Click the Download Selected Tabs icon.
3. Note the change in Position %.
4. Click Trend menu and Position Setup , enter 100% in Manual Setpoint field and hit
the Tab key. Red box in Figure 11.

5. Check the travel scale on actuator to make sure 100% in DTM matches 100% on the
travel scale.

Manual or Auto mode before returning to operations.
