3.3 Selection of Proper Switching Sequence
There are 10 different program modes which determines the power ratio
sequence of the capacitor steps. The switching programs are given in the
table. If the step sequence is selected as in program 02(PS-02), many
identical connection components must be used. When a step sequence
between the 3rd and the 8th one is selected, less identical connection
components will be used. By selecting the 9th connection sequence,
different group powers can be achieved. In this sequence connection, the
rating of each capacitor step value may exceed that of the first by a
maximum amount equal to the preceding capacitor steps value. By
using this setting, less capacitors will be used. When the 10th connection
sequence is selected, RG3-15C/CS/CL/CLS will calculate the capacitor
step power values automatically.RG3-12C/CS/CL/CLS counts swithing
on&off times of all capacitor steps and so only the most necessary step
is switched on. Thus, maximum service life time of the system is
ensured.
NOTE: In the 10th program(PS-10), power values and
connection types(except the first step) of the single phase
capacitor steps(r, s, t, rst, oFF) can be set by user. In Auto
setup mode power values of all capacitor steps are measured
and connection types of the capacitor steps are detected
by the device. In all the connection sequences except the
10th one, only the 1st capacitor step power can be set. All
the other capacitor step values are calculated according to
the 1st capacitor steps power value.
Set the program option suitable for your system in this menu
.
Press the “SET” button for 3 s in order to enter the menu.
Using the
“UP/DOWN”
buttons, select the Program (Prog) menu.
When program menu is displayed, program LED turns on.
SAUE
If you want to leave the setup menu without making any other
changes, press the

shows
on the screen. If you want to save the changes, press the
“SET”
button. If not, press the
“ESC”
button.
Press the
“SET”
button to select the switching program.
Enter the desired program number between 01-10 and press the
“SET”
button.
Using the
“UP/DOWN”
buttons, enter to another menu option
which you wish to change. If you are not going to change any
more settings, press the

In order to decrease harmful effects of instant reactive power loads to the
relays and capacitors, delay time (in terms of seconds) for capacitor steps
is entered in this menu.
Switch-on delay time must be set according to system requirement in
order to achieve compensation targets and also to provide long life time
for contactors and capacitors.
3.4.a Switch-On Delay Time Setting
NOTE: t-on and t-of time periods must be set according to your systems
requirements. If t-on time is set very long, relay can not switch on until
the end of this time period and so target compensation ratios may not
be achieved. If t-on time is set too short, capacitor steps switch on&off
frequently in case of fast load variations and this will shorten the life
time of contactors and capacitors. For this reason, it is very important
to set these time periods according to your system’s requirement.
Using the
“UP/DOWN”
buttons, select the delay time menu
(dELy).
When delay time menu is displayed, time LED turns on.
