Adding a Gas Switching Valve Event to the Run Table

For switching valves, two run time entries are required—one to switch the valves
on and one to switch the valves off.

2. Scroll to

Add run time event

and press ENTER.

3. Select

Valve

and press ENTER.

4. Scroll to the Switching valve that you want to add and press ENTER.

The

Run time

parameter is the time into the run when the valve switches to the

new position. The

Setpoint

parameter is the position that the valve will go to at

the selected time. The

On

value usually designates a clockwise switch and the

Off

value designates a counterclockwise switch.

If you want the valve to switch back to its original position at the end of run, then
do not need enter a second run table entry.
