This is the section in which the fast step mode is enable or disable. In case "enable" is selected,
the device can activate many steps at the same time as well as de-activate them. If "Off" is
selected, then the device makes only one step attempt at each time.
The required status for function is selected by using the up
and down keys. Press "Apply" key in order to take this parameter
into memory. "Save changes" message will appear on the screen.
When "Okay" key is pressed, the value is taken into memory.
In case fast step mode is activated, the device set ΔT on and
ΔT off times to zero automatically.
If fast step mode is selected, then the contactors which will be
used, must be absolutely compensation contactors, and the step
activating time (discharge) that the producers recommend, should
be entered.

This is the section in which the continous internalization of step power is activated or de-activated.
In case "Activated" is selected, the device checks the step power at each step activating and de-
activating operation. In case of a change in power, then the device determine it and start to use
this value. If the last value of the capacitor is decreased by 50% than the power value of the initial
internalization, the device warns the user about the decrease in power of capacitor. It continues to
make compensation with the value internalized finally. In case "Off" is selected, the device can
only internalize the capacitor powers on the first
commissioning. It determines the change, but continues to
compensation with the values of initial internalization.
P.S.: It can be necessary to disable the function of step power
İnternalization in some plants (especially, the plants in which the
loads are changing very quickly).
The required status for function is selected by using the up
and down keys. Press "Apply" key inorder to take this parameter
into memory. "Save changes" message will appear on the screen.
When "Okay" key is pressed, the value is taken into memory.

This is the section in which the constant step function is activated or de-activated.First step
switch on and stay at this position if this function is enable . This function is only used in activating
constant capacitor to meet the loss of transformers in the counters measure the medium voltage.
This capacitor must be connected ahead from the current transformers. Using the step of the
device for constant capacitor is not recommended actually. Much more steps are required for
compensation.
Consequently, constant capacitor can be connected to switch
input with a on-off switch. In case "Off" is selected, the device starts
to use this step.
The required status for function is selected by using the up
and down keys. Press "Apply" key inorder to take this parameter
into memory. "Save changes" message will appear on the screen.
When "Okay" key is pressed, the value is taken into memory.

This is the section of activating or de-activating the simultaneous use of levels in the same power.
In case "Activated" is selected, device tries to make the used hours of capacitors in the same
power equal.
The required status for function is selected by using the up
and down keys. Press "Apply" key inorder to take this parameter
into memory. "Save changes" message will appear on the screen.
When "Okay" key is pressed, the value is taken into memory.
