Menu.2.3.1
It is the third of 7 different setting parameters in the step menu. To change the Step Time
Settings, press the SET button while the Step Time Settings page is on the screen. To change
the current value, the relevant parameter must be selected with the RIGHT button. The selected
parameter is indicated by the "
>
" sign on the left side.
Drive Time:
It determines the activation time of the step to intervene in the power change in
the system.
Factory Setting = 2.0sec. , Setting Range: 1sec, – 30sec.
Then the selected value can be changed with UP / DOWN buttons. The changed value is saved
by pressing the SET button.
Discharge Time:
It determines the duration of the capacitor discharge (being able to
reactivate the same stage).
Factory Setting = 15sec. , Setting Range: 1sec, – 60sec.
Settling Time:
When the device needs to activate several steps at once, it determines the time
to wait between the steps.
Factory Setting = 400msec. , Setting Range: 100msec, – 3000msec.

Menu.2.4.1
It is the fourth of 7 different setting parameters in the step menu. To change the PFC
Settings, press the SET button while the PFC Settings page is on the screen.
To change the current value, the relevant parameter must be selected with the RIGHT button.
The selected parameter is indicated by the "

PFC:
It enables/disables the device's intervention to reactive powers in the system with
capacitors and shunt reactors. When PFC is disabled, the device does not activate steps.
TCR:
Activates/deactivates the device's intervention to reactive powers in the system with an
inductive load driver (if the system has an inductive load driver). When TCR is passive, the
device will not activate the inductive load driver.
>Drive : 3 sec.
Release Time:
It determines the time for releasing the step that is activated to interfere with
the power change in the system.
Factory Setting = 2.0sec. , Setting Range: 1sec, – 30sec.

Menu.2.5.1 Control
It is the fifth of the 7 different setting parameters in the step menu. To perform the Step
Check, press the SET button while the Step Check page is on the screen.
You can navigate between the levels with UP/DOWN buttons, you can use the RIGHT button to
control/activate/deactivate the steps and to deactivate the active steps.
When you return to the measurements screen by pressing the ESC button, the device will
inactivate these stages one by one if there are activated stages.

Manual Step Value Set
It is the sixth of the 7 different setting parameters in the step menu. To enter the manual step
value, press the SET button while the Manual Step Value Enter page is on the screen.
In this page, you can navigate between parameters (Step, Type and Value) with the RIGHT
button, and change the value in the selected parameter with the UP / DOWN buttons.
To change the current value, the relevant parameter must be selected with the RIGHT button.
The selected parameter is indicated by the "
>
" sign on the left side.
After entering the step information manually, SET button is pressed to save. The step
information recorded after the saving process and the “Step Approved” notification appear on
the screen.
To exit without saving, pressing the ESC button will return to the Manual Step Value Set page.
Example:
On the screen above, the three-phase 10kVAr capacitor value has been entered in
the 1st step.
If the value to be entered is single phase, “L1, L2 or L3” should be selected from the phase part
according to the phase to which it is connected. If the value to be entered is two phase, “L12, L23 or L31”
should be selected from the phase part according to the phase to which it is connected. If the value to be
entered is three phase, “L123” should be selected.
Note:
Capacitor values a re entered as (-) signed with DOWN button. Shunt reactor values a re entered
unsigned with the UP button.

Offset:
It is the value used for reactive powers between the electricity meter and the reactive relay that the reactive
relay cannot measure. This value that the device cannot measure is calculated software and intervened accordingly.
Example:
If offset is entered as -10kVAr, it means that there is a three-phase 10kVAr capacitive power that the
reactive relay cannot measure. The reactive relay will interfere with this power, in addition to the target cosine value,
with three-phase 10kVAr inductive power. (If offset capacitive (-) is entered, the power to be applied becomes
inductive (+), If offset inductive (+) is entered, the power to be applied becomes capacitive (-).)
