 On the screen shown on Fig.25, use the arrow to change the digit and use the arrow to
change the value. The kvar value will be programmed for each step and it will be confirmed by pressing
OK .
NOTE: After programming the first step, all other steps will change their values, using the value of the
first one (20 kvar in the case shown on Fig.25). The screen on Fig.24 will be displayed and we can then
program the next step. Assume that the second step is 40 kvar. Select the second step with and
repeat the operation to program value 40. When this operation is complete, press OK . If we assume
that the third step is 80 kvar, follow the same procedure. The screen shown on Fig. 26 will be displayed,
where all steps after the last step programmed also have the value 80.
 Number of steps: The previous screens show 16 boxes. This means that Computer plus TF-C and TF-
CDI can govern up to 16 capacitor steps with a static capacitor bank. When the unit has fewer steps, for
example, 11 steps in a Computer plus T8, program step N+1 as zero (in the example on Fig. 28, step 12)
and the regulator will then know the number of steps used (in our example, 11 steps).
