It' a useful function in terms of warning the user. First, it' s
better to clarify some definitions step alteration control page:
Old value : The first internalized power of step.
New value: The power alterated minimum ± 15% with respect
to the past value.
This page has been designed to identify and enter the real
value of steps whose powers are not internalized, even though
the powers are alterated over time or replaced with the past
one by the user.
In case the new value of any step is alterated ± 50% with
respect to the first value, the device warns the user as
"Change in the power of capacitor". If the capacitor in which
alert is given has really alterated, then the new value should
be loaded instead of the past one. The alteration in step power
appears on the screen as a warning
In case internalization of step power is activated, the device
controls the capacitor power at every step activation and de-
activation process. In case of a change in the power, the
device determines it and continue to compensate with the final
value internalized. If "Off" is selected, the device internalize
capacitor powers only at the first activation. It determines the
alteration, however continues the compensation with the first
internalized values.
The device directs the user with sub-command screen
continuously. The red frame is moved on the step whose
power decreased (box in blue colour) by using up and down
keys and "Select" key is pressed.
Sub-command screen is alterated. In case of which value will
be used, past or new value key is pressed and then load key is
presse. "Load selected value to step?" question appears on
the screen. If "Yes" key is pressed, load will be completed.

The device directs the user with sub-command screen
continuously. In case of entering into the parameter, the
commands on the sub-screen are alterated as shown on the
right side. In this case blue line appears under the first digit of
the parameter. The value is alterated by using the up and
down key starting from the digit where the blue line is. Then
left key is pressed and the blue underline moves next to the
left digit. All values are entered in the same way by using up
and downkeys.
