Using the CLS
Operator Menus
You can reach the following Operator Menus from Single Loop Display.
(If your CLS is already installed, try each procedure as you read about
it.)
Change Setpoint
To change the setpoint, go to Single Loop display of the loop you wish
to change, and then press the Change Setpoint key. (The setpoint is the
desired temperature, pH, et cetera, for the process.) You should see a
display like this:
• Press Yes to change the setpoint.
• Then press Yes or No to change the setpoint value.
• When you are satisfied with the setpoint value you have chosen,
press Enter to save your changes and return to Single Loop Display;
or
• To return to Single Loop display without saving your changes, press
No or Back.
Manual/Automatic Control
Press the Man/Auto key to set a loop's control mode, set manual output
levels, or automatically tune a loop. The control mode determines
whether the CLS automatically controls the process according to the
configuration information you give it (Automatic control), or you set the
output to a constant level (Manual control).
If both outputs are disabled when you press the Man/Auto key, you'll
see a display like this one:
