8LS Users Guide 101
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
table shows the available codes and their meaning.
This is the Single Loop display when a profile is running.

RUN The profile is running.
