1. INTRODUCTION
1.1 General Information
Power factor controllers are used for measurement and control of power
factor control units for central reactive power compensation. The power
factor, which is defined as ratio of active power (W to apparent power
(VA , measured by power factor controller is compared with the set values
to provide necessary compensation.
RM-12P power factor controller is designed for reactive power compensation
in single phase and 3-phase systems.
RM-12P compensates each phase separately and so, this makes
RM-12P series a unique solution for unbalanced load compensation. In
order to perform this process, single phase and 3-phase capacitor steps
must be connected to the device at the same time.

Connection type of auxiliary supply, voltage measurement input and current measurement input must be 3 phase-neutral. Device
must be operated after finishing of the 3-phase connections.
After the device has energized, it finds connection errors and corrects automatically.
Phase current should not be aqual to zero in order to let the device to sense the connection error. Device sense the connection error
according to Active Power direction.
Device switching ON and OFF the 1st steps 3-phase capacitor during the correction of connection errors (Phase sequence error and
polarity error of Current Transformer . Device may not correct the connection errors if there are too many instant variations for loads and
nonlinear loads (Such as Thyristor or triac controlled frequency inverter, UPS etc. . In this case, user should disconnect the device and restart
it to making the same operation.
This operation also can be operated as turning ON the Auto SET function in Auto menu. In this case device corrects the errors and
then calculates the capacitor values.
After connection errors are corrected; capacitor steps are calculated with turning ON the Auto Setup function in Auto menu (Refer to
Automatic Capacitor Recognition menu .
It is an obligation to connect a 3-phase capacitor for 1st step. All steps are measured seperately if the program-10 (PS-10 is selected
in Program menu. In this program (PS-10 ; single or 3-Phase capacitors can be connected according to requirements of the system in
any sequence.In case of choosing one of the other programs, device measures the 1st steps power value and then calculates the other steps
respectly to this value. Device calculates the capacitor values which will be switched ON according to selected program; device switches
ON / OFF the required steps.
Connection of circuit breaker or automatic fuse is highly recommended between the network and RM-12P. Circuit breaker must be
in close proximity to the device.

2. INSTA ATION
When RM-12P is powered-up for the first time, if the power value of
any phase is negative, RM-12P switches on&off the first capacitor step
automatically and it recognizes and records the connections.
Later, automatic setup (Refer to page 6 - Automatic setup is selected
on the menu in order to automatic recognition of the connections and
connected capacitor steps.
After automatic recognition, RM-12P checks all capacitor step values.
If variable loads exist in the system, first of all these variable loads must
be disconnected and then automatic setup process must be done.
Otherwise, power factor controller may not measure capacitor step powers
correctly. Capacitor step powers and connection types also can be
recognized to the power factor controller manually.
(Refer to page 10 - Setting of the capacitors connection and power values
After the recognition of capacitor step powers, target Cosj
value is set in order to start the compensation. Factory set value for target
Cosj is ind. 1.000 and Cosj2 is ind. 0.900
Note: PFC decreases the switching on&off time to 3 seconds in
Automatic Setup mode but discharge time is not changed. After the
automatic setup process, set values become valid.
Device finds connection errors and corrects automatically. Power
values of the capacitor steps are measured automatically according
to program selection. If PS-10 program is selected, power values of
all capacitor steps are measured (Refer to Program Section . If any
other program is selected, device measures first capacitor step value
and then calculates other capacitor steps according to the selected
program. For this reason,
a 3-phase capacitor must be connected to the first step. Then, single
phase and / or 3-phase capacitors can be connected with random
sequence to the other steps.

3.1.b Automatic Mode Setting
When device starts to operate, it checks connections and if
there is a connection error, corrects it automatically. For this
function, 3-phase voltage and current connections must
completely be done.
Warning: If fast load variations exist together with
compensation capacitors, device can not detect correct
connection at first time but after several attempts. If device
can not finish this detection, C/k calculation can not be
accomplished.
After correcting connection errors, if Auto:On option is selected

to program selection. When PS-10 program is selected, all
capacitor steps are measured. In other programs, only first
capacitor step power is measured and other capacitor steps
are calculated and recorded according to the selected program.
Note: After this process, calculated power values of all
capacitor steps always must be controlled. 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
supposed to be 1 and capacitor powers are calculated
according to these values.

3.4 Switching Program Setting
RM-12P has 10 different program modes which determines the
power ratio sequence of the capacitor steps.
Three different switching programs are supported by RM-12P.
a) inear Operation: The switching program begins always from
the first step to the last one in both switching on and off mode.
The advantage of this switching program is the possibility of a
large selection of capacitor steps. This switching program is
selected by 01 option.
b) Rotational Switching: This switching program is rotational
between equal steps in the clockwise direction and this switching
program is rotational to ensure that the capacitor switching cycles
are uniformly distributed over all steps and to provide minimum
switching steps for maximum service life time of the system.
There are 8 different rotational switching programs (02, 03, 04,
05, 06, 07, 08, 09 .
The ratio between capacitor steps is very important. When choosing
the ratio between capacitor steps, the rating of each capacitor
step value may exceed that of the first by a maximum amount
equal to the of the preceding capacitor steps value.
c) PS-10 Program: If PS10 program is selected, RM-12P
calculates electrical parameters of the capacitor steps
automatically. RM-12P counts swithing on&off times of all capacitor
steps and so most necessary step is switched on.
Thus, maximum service life time of the system is ensured.
NOT: In PS-10 program, connection types and power values of the
single phase capacitor steps can be set by user. In Auto setup mode
power values of all capacitor steps are measured.
In other switching programs, only first capacitor steps power value
can be set (except PS-10 program). Other capacitor steps power value
are calculated automatically according to the first capacitor steps
power value.
Press UP/DOWN buttons to select program (Prog) menu.
In this menu capacitor steps sequence is selected.

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.
3.5.a Switch-On Delay Time Setting
Note: t-on and t-of time periods must be set according to the 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 can not
be achieved.
If t-on time is set too short, capacitor steps switch on&off frequently
incase of fast load variations and this causes to shorten the life time
of contactors and capacitors. For this reason, it is very important to
set these time periods according to your systems requirement.
Press UP/DOWN buttons to select delay time (dE y) menu.

3.6.a First Capacitor Step Setting
First capacitor step is used to find connection. For this reason, 3-phase
capacitor must be connected to the first step. So, connection setting for
first capacitor step is not possible and always RST connection type is
selected.
When setup parameter is selected as on in Auto menu, if any program
(except PS-10 , is selected, power value of the first capacitor step is
measured and other steps power values are calculated according to
selected program. When Setup:of is selected, power values of all
capacitor steps (including first capacitor step can be set manually.
Note : When setup parameter is selected as on in Auto menu, after
completing the measurement of capacitor powers according to the
selected program, RM-12P continues to work in setup:off mode.
In this menu, power values and connection types of all capacitor steps are
set.
There are 5 different connection types for capacitors which are R, S, T,
RST and off. Also capacitor step measurement for power values can be
set between 0,02-2,00. If off option is selected, there is no need to set
any power value.
Note : For first capacitor step, different connection type is impossible
andRST connection type always must be selected. Because first
capacitor step is used to detect correct connection.
Note : If PS-10 program is selected, capacitor powers can be set
separately for each capacitor step. However, if any program, except
PS-10, is selected, only first capacitor steps power value (C-01) can
be set manually. Capacitor powers for other steps are calculated
according to the selected program.
