Running several profiles simultaneously

To run several profiles simultaneously, follow these steps:

1. Setup the profiles so that segment 1 of each profile has the same

latched trigger.

2. Assign the profiles to the appropriate loops. The loops will go to the

Ready segment of each profile.

3. Set each profile to Run mode.

4. Trip the trigger.

Editing a profile while it is running

You can edit a profile while it is running, but the changes you have
made will not take effect until the next time it runs.

Ramp/Soak Displays

The Single loop and Bar Graph displays show additional codes for R/S
controllers.

Single loop display

When the controller is running a profile, the Single Loop display shows
the profile mode where it would usually show MAN or AUTO. The next
