DIMENSIONS
Do not use device without checking terminal connections.
CONTROLS and OPERATIONS
Capacitor values are recognized and saved with ASEt operation. For doing this, enter
program menu on the device and find ASEt menu. ASEt menu includes 2 parameters
which are S-oF and S-on.
When S-on is selected and SET button is pressed; the device will find and correct
any connection failures (such as wrong connection at voltage and current inputs) first
and then recognize all capacitor steps. If 10th program (PS-10) is selected, all capacitor
powers will be measured. In other programs, only first capacitor step power is measured
and other capacitor steps are calculated and recorded according to selected program.
If S-oF is selected and SET button is pressed during capacitor recognition, automatic
recognition will be ended.
Note: If there are loads other than compensation on the system, the device may
find the connection after several tries. If the device doesnt complete the automatic
connection process, it cant do the step calculation process. In order to have
correct power values for capacitor steps, current and voltage transformer ratios
must be entered correctly. If current and voltage transformer ratios are not entered,
these ratios are assumed to be 1 and capacitor powers are calculated according
to these values (Refer to VT and CT ratio settings).
If automatic setup is selected as S-on, automatic mode starts immediately
without waiting to escape from the menu.
Note: A parameter that is calculated automatically by the device can be changed
by the user.
Automatic Capacitor Recognition and Phase Setup Mode

For proper operation, current and voltage connections must be connected as
shown in the connection diagram.
After current and voltage terminal connections, capacitor steps connection must
be done according to the connection diagram.
Lastly, computer communication connection must be done.
Do not power-up the device before verifying terminal connections.

Device can detect wrong connection on the way of active power. For correcting connection
fault, automatic setup must be done or suitable phase value must be programmed from AngL
menu, which is for programming phasor angle, from transformer menu. When user does
automatic setup (ASEt), device will open and close 3 phase capacitor in 1st step during
correction of connection failure. Sudden changes in loads and nonlinear loads (Thyristor or
triac controlled frequency inverter, UPS etc.) existing, automatic setup may not be done. In
this condition, user should disconnect the device and restart it and make the same operation.
This operation can do with selecting S-on under ASEt menu. In this case device corrects
the errors and then calculates the capacitor values.If user does not want calculating capacitor
values, selecting S-oF parameter provides this.
User must enter capacitor values after entering current and voltage transformer ratios. Capacitor
values can be calculated automatically or maually. Capacitor powers are measured automatically
by entering S-on under devices ASEt setting (for details please look Operating Mode
Settings). If 10th program (PS-10) is selected in program menu, all capacitor values are
measured by switching on/off of the capacitors in sequence. In this program, 3 phase capacitors
can be connected as desired according to system requirements. If capacitor steps have been
calculated as in the previous step, this step is not necessary. Selecting other program condition
device only calculate 1st step and other steps will be calculated according to selected program.
Device calculates the capacitor values which will be switched ON according to selected
program; so device switches on/off the required steps.
Connection of circuit breaker or automatic fuse between the network and RG-B/BS series
is highly recommended. Circuit breaker must be in close proximity to the device.
All used fuses must be FF type and the current values of the fuses must be 2A or 3A and
6A (Refer to Connection Diagram).
Generator input must be done only when the network is supplied by the generator. Otherwise
device will be switched to the generator position for each generator starts including the
maintaining purpose.

Operating Mode (Automatic/Manual Mode) Settings
RG-B/BS series has two operating modes which are automatic mode and manual
mode. Operating mode can be selected by selecting A-on (automatic) or A-oF
(manual) option. Manual mode is used for test purpose. In this mode, capacitor steps
are switched on&off to test the relay outputs of the device. In the manual mode,
capacitor steps are switched on by pressing SET button and also capacitor steps
are switched off by pressing ESC button. Factory set values for switching on (ond)
and switching off (oFd) time is 10 seconds. These time values can be programmed
in the Delay (dELy) menu (Refer to delay time setting). In the manual mode, step
numbers, which will be switched on&off, can be programmed in Step menu (Refer
to step number setting). Even if manual mode is selected, after 5 minutes, device
starts to work in automatic mode and continues to operate in automatic mode.
When automatic mode is selected, AUTO/MAN LED lights on continuously.
When manual mode is selected, AUTO/MAN LED blinks.
Warning: Device warns user by blinking (short ON, long OFF) the capacitor steps
which will be switched on. Also device warns user by blinking (long ON, short
OFF) the capacitor steps which will be switched off.
For switching capacitors; voltage inputs must be connected and measured
voltage must be higher than (min. 0.5 times) programmed nominal network
voltage.
* Current value of 3-Fuses, which are connected to protect the capacitors, is
chosen according to the nominal current value of capacitors.
** At 3 phase 4 wire applications L1 and Neutral must be connected devices
voltage measurement inputs, at 3 phase 3 wire applications L2 and L3 phases
must be connected. L1 phases current transformer must be connected to
current measurement input. If load is unbalanced, current cable which is
nearest value of total average value must be connected to current transformer.
In this condition voltage inputs must be set refer to current. When device
programmed to automatic setup, it will program suitable phase angle. So it
will measure true values and true compensation.
*** Communication terminals are only available in BS models.

Step Number Setting
The maximum number of steps that the device can control depends on the device
model. It can be 6, 8 or 12 . Each of these steps can be programmed oFF, oN or
Auto in the
10th
program.
AUto : Programming capacitor power (kVAr) menu.
on : Capacitor programmed as a steady.
oFF : Meaning of there is no capacitor connection at output.
When other programs are selected, 1st steps capacitor power can be programmed.
Other steps power can be programmed according to selected program.
* Recommended program mode.
RG-B/BS series has 10 different program modes which determines the power ratio
sequences of capacitor steps. These are given on the tables below.
If capacitors sequence is set just like 2nd program (P-02) (1.1.1.1.....), many identical
connection compenents are required. Selecting between 3th program (P-03) to 8th
program (P-08),less connection components are used (exp: 1.2.2......). 9th program
(P-09) provides different group powers. 9th programs capacitor sequence working
principle is one groups power can be higher than previous groups sums by first
group power. With this method, less capacitors can be used. For 10th program (P-
10), there is no rule of arranging the steps from low to high. With auto setup, capacitor
steps can be calculated automatically or user can enter the capacitor values manually.
User can select used or not used capacitor steps from CAP menu at 10th program.
