Table 4. Configuration menu parameters
6.1. Target cosF setting (CoS1, CoS2)
Press the button
SET
at least for 5 second for entering configuration mode. On the display will appear parameter symbol
CoS1
. After another pressing of button
SET
display will show set value. Via buttons
▲
,
►
set new requested value in the
limits from 0,8 inductive to 0,8 capacitive. Another pressing of button
SET
saves new value to the memory and on display it
will appear again symbol
CoS1
.
For programming
CoS2
follow the same instructions as previous case. For changing from
CoS1
to
CoS2
it is necessary to
connect auxiliary supply of 230 V AC to the terminal marked as
2nd Tariff
on the connection diagram.
6.2. Setting of transformer ratio (I_tr, U_tr)
If
SET
mode is activated, move by buttons
▲
,
►
to the parameter
I_tr
. After pressing button
SET
, the set value will appear
on the display. Via buttons
▲
,
►
is possible to change value of transformer ratio. Another press of button
SET
saves new
value to the memory and on display, symbol
I_tr
will appear again.
It is important to have in mind that the value which is set, is ratio itself. It means that, for example, if primary nominal current
of transformer is 50 A and secondary is 5 A then set parameter value is
I_tr
= 10.
In case of voltage transformer usage, parameter
U_tr
should also be set the same way.
Caution
Measurement range of the current inputs is from 3 mA to 6 A. Maximum of the current transformer ratio is 30000 / 5 A.
6.3. Automatic detection of compensation steps (Auto)
Another parameter in the menu is function
Auto
. After pressing of button
SET
, the display will show
oFF
. Via buttons
▲
,
►
change to the value
on
. After double pressing of button
SET
automatic detection will start to detect connected stages. The
symbol
CoCo
will appear on the display, and first capacitor stage will be switched on and off 6 times in the cycle of 20
seconds.
Detection of regulator connection to the network is followed by detection of power of connected capacitor stages. During
detection, the measured values of each stage are shown on the display. Measured values are being rounded on 0,5 kvar. After
the detection is finished, the regulator will switch parameter
Auto
back to
oFF
.
Important
In some cases regulator is not able to make automatic detection and in place of measured power shows zeros. It can happen
in places with very fast changes of network parameters, where measured values will not be correct. In this case regulator
shows Err1 and it is necessary to set parameters manually, after detailed network measurements.
6.4. Deceleration of regulation at over compensation (SHtd)
This parameter is represented by symbol
SHtd
. This function is used for slowing down the regulation during over-
compensation. At under-compensation regulation is slowed down according to average power factor. This function assures
reduction of switch on/off operation of contactor stages. After pressing the button
SET
, display will show set value of
deceleration. By buttons
▲
,
►
it is possible to change value and button
SET
saves this into the memory. Current situation of
regulation deceleration during over-compensation is shown under parameter
SHtd
, in the menu of measured values.
6.5. Manual setting of compensation stages (St_P)
After parameter
Shtd
, the parameter that follows in the menu is
St_P
. Pressing the button
SET
will enter the sub menu,
where it is necessary to select the stage, which has to be set, via buttons
▲
,
►
. Selected stage will be signalized by green
LED. By pressing button
SET
on display will appear set value of stage that is signalized by relevant green LED. Via buttons
▲
,
►
it is possible to change the value and by pressing button
SET
to save this into memory. Via buttons
▲
,
►
select
another stage, which must be set and follow the same procedure as before. After setting of all stages, keep pressing button
SET
until display will show
St_P
and all LED's will be off.
