Programming, Chapter 7
Sample Program
1. Start your profile by pressing the Hold/Run key. You can be at any
point except in the Setup or Factory menus or with the control in the
auto-tune mode.
2. The Run LED begins flashing. The upper display shows the file number
to be run and the bottom display shows the FiLE parameter.
3. Press the Mode key, the upper display shows the step number to be
run and the bottom display shows the StEP parameter.
4. Press the Hold/Run key again. (If not pressed within approximately 1
minute, the Run procedure will abort.) The profile starts running.
The Run LED is continually lit. The upper display shows the process
value, and the lower display shows the current set point.
You may step through the Run menu parameters with the Mode key while
the profile is running. The Run menu will show the file number, step
number, the step type and what the parameters are set to. At any time
you may press the Hold/Run key to stop the profile. To resume running
the profile where it was stopped, press the Hold/Run key once; the Run
LED begins flashing. Now, press the Mode key to advance to the rESU
parameter; once again, press the Hold/Run key. After the profile has
ended the Run LED is off and the lower display reads OFF. This means
the End step was selected as OFF, disabling all outputs.
Editing Your Profile
Now let’s try editing the profile by expanding it with another ramp step,
adding a jump-loop and allowing the program to end in a Hold mode. It
is possible to expand the number of steps in a file to 7 if the final step
can be an End-Hold step. We’ll jump to Step 2 and repeat Steps 2
through 5 two more times. This is accomplished by programming a Jump
Step (JS) = 2 and Jump Count (JC) = 2. This means that once the Series
981/982 goes through the profile and reaches Step 6 it jumps back to
Step 2 and repeats the profile two more times (Steps 2 - 5). The program
then ends and holds the set point and event status of the last step of the
profile prior to ending the program.
