Pre-run and Run Menus
The Pre-run and Run menu prompts are only visible when in the Pre-Run or Run mode. The Pre-run mode is entered by pressing
the
ˆInfinity key one time while at the Home Page location. The profile indicator light flashes while in the Pre-run mode. The
Pre-run menu consists of the
[file], [step], [resU] and prompts. The Pre-run menu allows the user to select a profile and
step number to run or to resume running a profile. The Pre-run menu contains these three prompts and does not revolve around in
a continuous loop. Pressing the
‰Advance key at the [resU] prompt will not advance you back to the top of the Pre-run menu.
If the ‰Advance key is pressed at the [resU] prompt, the user will exit out of the Pre-run menu and return to the display of
process/current set point. The Run mode is active when a program is running. The Run mode is entered by pressing the ˆInfinity
key one time while in the Pre-run menu. The profile indicator light will be full on while in the Run mode. The [f-st] file-step
prompt is visible in the Run menu and shows the current file and step number of the running profile. Other prompts in the Run
menu show the target end set point, as well as status for time remaining, ramp rate, wait-for, and jump count if relevant.

Running a Profile
1. You must be at the Home Page location before you can begin running a profile. Start your profile by entering the pre-run
menu. Enter the pre-run menu by pressing the infinity key.
2. The profile indicator LED begins flashing. The upper display shows the file number to be run and the bottom display shows
the
[file] parameter. Use the ¿ Up and ¯ Down arrow keys to select which profile number to run.
3. Press the ‰Advance key, the upper display shows the step number to be run and the bottom display shows the
[Step]
parameter. Use the ¿ Up and ¯ Down arrow keys to select which step number to start ramping at.
4. Press the ˆInfinity key again and the profile will start running. If not pressed within approximately one minute, the controller
will automatically exit out of a pre-run mode. If the ˆInfinity key is pressed within one minute, the profile indicator LED will
change from flashing to being continually lit to indicate the profile is now running. The upper display shows the process value
and the lower display will show the ramping set point or soak set point value.
5. You may step through the Run menu parameters with the ‰Advance key while the profile is running. The Run menu will
show the file/step number, and what the parameters are set to. At any time, you may press the ˆInfinity key to stop the profile.
To resume running the profile where it was stopped, press the ˆInfinity key once; the profile indicator LED begins flashing.
Now, press the ‰Advance key repeatedly until the [resU] parameter appears in the lower display; once again, press the
ˆInfinity
key and the profile resumes running. After the profile has ended, the profile indicator LED will turn off and the lower
display will read [`Off] or the last profile step set point depending on the [`end]
prompt setting.
Resume a Profile
To resume a halted profile, from the Home Page, press the ˆInfinity key once to enter the Pre-run Menu. Press the ‰Advance
key twice until the
[resU] parameter appears in the lower display. The lower display will show [resU] and the upper display
will show the file and step number that will be resumed (file-step). Press the ˆInfinity key again, the profile resumes, and the
profile indicator LED is lit. You can only resume at the exact step you left off on. If you halt a running profile and make changes
to the current step, you cannot resume the profile. The [resU] parameter only appears when a running profile has been halted.
To Run your profile... Press the ˆInfinity key twice.
