Program Display

Pressing the Program key displays the default program status page.

This screen displays the following information:

•Program No. – the last program number loaded into the program run buffer.

•Status – Displays if the program is running, in hold or stopped.

•Remaining Time Step – Time remaining in the current step

•Total – Total run time of the current program

•Program listing – displays all 24 steps for the program. If the program is running the active step number is highlighted.

NOTE: See “Sample Recipes” at the back of this manual for Recipes “50”, “51” and “60”.

The Program display has six active buttons located on the right-side of the display. These are activated by touching the inside of the blocks. The active buttons are: Soak Adjust, Load, Stop, Hold, Cont, Alm Ack (Alarm Acknowledge) and Esc.

•The Soak Adjust button allows you to enter a new value for the time remaining in the current soak cycle. A soak cycle must be running for a change in soak time to be adjusted.

•The Load button allows the operator to enter the recipe number to be run and to view the recipe before pushing the Run button. Pushing the Run button starts the recipe. If a recipe program is running and the operator enters a new recipe program, it can be viewed and modified. The recipe does not become active until the Run button is pushed. Pressing Run places the program currently being viewed in the active memory and will begin to run the new recipe. You can start the program in any step simply by moving the highlight down to the step that that the program needs to be started in, and then pressing the Run button.

While reviewing the program that is about to be run, certain parameters within those steps can be modified. You can change the set points, the time and the options. You CANNOT delete a step, or modify its Op Code.

•The Stop button stops the recipe program that is currently running. Stop means exactly that. It stops the program. It is NOT a hold button. See Hold below. To re-start the program if it has been stopped, you must use the Load button, enter the recipe number, and then enter the segment number of the recipe that you want to start with.

•The Hold button places the displayed recipe program in “hold”. Once a decision is made that affects the recipe it may be continued by pressing the Cont button.

•The Cont button re-starts the displayed (active) recipe only after it has been placed in Hold.
