10-2. Using the worksheets
The worksheets included in this manual for Program 3 and Program 1 help to make your
programming simple and accurate. We recommend that you fill out the pertinent worksheet before
attempting actual programming.
1) Carefully read each definition and specify a selection.
Each definition is following by a Specification column which contains numeric values(Usually to
indicate a simple YES or NO answer). Determine the correct value according to your need and
enter it in the Selection column to the right.
2) Total each set of selections to calculate each program code digit.
Three selections(a,b,c) make up a set. Add up each set of selections and fill in the totals in the
Program code column for data items D8 through D1.
3) Program the feature or function.
Be sure that you have filled in all of the selections and program code digits for the entire worksheet,
and follow the procedure noted for the feature or function you are programming.
4) Check the printed program receipt against the worksheet.
Perform program read operation in each program mode to print setting which you have
programmed, to check then against the worksheet. We recommend that you do so and keep a copy
on record to help out should it become necessary for you to change the program.
