Manual Find Stops

On some very large valves or valves with non-Masoneilan actuators, it is possible that the

automatic Find Stops procedure will not find the correct end positions of the travel. A

semi-automatic method of calibrating the stop positions is provided.

To calibrate the position:

1. Select Full Closed from the menu to close the valve.

2. When the valve is fully closed, select Set as Closed Stop.

3. Select Full Open from the menu to open the valve.

4. When the valve is fully opened, select Set As Open Stop

For some valves the open position stop exceeds the nominal travel of the valve. By entering a

value in the Open Stop Adjustment the position calibration can be adjusted to nominal travel.

Menu - Calibrate

When you right-click on the Calibrate tab, a context menu appears.

Run Find Stops Runs the automatic position calibration process.

Manual Find Stops Allows you to set full open and full closed and wait for the valve to

complete these operations before the SVI accepts the stop position.

This allows for setting the stops on very large valves which may not

work properly with the automatic find stops routine.

Run Auto Tune Automatically finds appropriate PID parameters for the valve.

Full Open Moves the valve to full open. This command work by taking the valve

out of closed loop control and send a high or low signal to the I/P.

Full Closed Moves the valve to full closed. This command work by taking the

valve out of closed loop control and send a high or low signal to the

I/P.

Reset to Factory Cal Resets the signal calibration to their factory setting. Report Setup –
