Energy ow direction: When mounting the transformer, observe the current ow or
energy ow direction. If the current transformer is mounted the wrong way round, the
measured current value will be negative.
A prerequisite for this is that energy is supplied to the device.
Assignment - Measuring voltage input / Current transformer input:
The current transformer on terminal 20/21 (k1/l1) must be installed in the phase in
which the measuring voltage for terminal 10 (L1) is measured.
– The device will display positive current when connection
and energy ow direction are correct.
- If connected incorrectly, the current displayed is negative. Interchange
the connections until the display shows correct values.

2.3 Terminal assignment
Terminal:
1 (L) and 2 (N): Power supply connection
A control voltage is required to supply the device with power.
The unit is equipped with a multi-range power supply and may
be supplied by voltages of 100 – 240V ± 10 %, DC 50/60 Hz (see
nameplate for device voltage).
10 (L1,Lx):
13 (N,Ly):
Voltage measuring input
Input voltage both as PH-N and PH-PH measurement. Direct
measurement for 100... 500...600V AC. The measuring range is
congurable. If the measuring range is exceeded, an error mes-
sage is displayed.
For higher voltages, connection via voltage transformers is
necessary (medium voltage measurement x/100 V), measuring
range from 500V to 30.0 KV Ph-Ph.
20 (k1) and 21 (l1): Current measurement inputs
The measuring input for current must be connected via a cur-
rent transformer x/1A AC or x/5A AC.
When connecting the transformer, pay attention to the energy
ow direction and to the correct assignment of measuring volt-
age input to current transformer.
30 (C) and 31 (S): Floating relay contact
This contact serves as a message or alarm output. During oper-
ation, an acoustic or visual message can be activated or a con-
sumer switched o using this relay. The contact is open as long
as the device is dead as well as when there is an active message.
Maximum switching capacity 2A at 250V AC.
40 (C): Connection for voltage supply to the relay output terminals
41 to 45
The relays for the control outputs share the same
connection to the supply voltage.

2.4 Device memory
Non-volatile long-term memory
The device is equipped with an internal, non-volatile memory in which long-term data is
stored.
Buered real-time clock (RTC)
After an uninterrupted charging time (device connected to the supply voltage) of approx.
8 hours, the buer capacitor will have a sucient charge to protect the internal clock
from failure due to lack of operating voltage for approx. 14 days.
NOTE
If the buer capacitor is discharged and there is no supply voltage, once the device has
been switched on the time settings will be incorrect and must therefore be reset.

Commissioning
3 Commissioning guideline
for the multicomp D6-xxx-7
This guideline helps you to correctly start up the compensation controller
multicomp D6-xxx-7 . It provides you with step by step instructions to help you nd
the options relevant for you in the operating instructions.
To begin with, there are two cases in which the commissioning procedure for the
multicomp D6-xxx-7 diers.
Case 1: You have bought a complete compensation unit from KBR, and the controller
is already installed. If this is the case, certain settings are already precongured in the
controller.
Case 2: You only bought the controller, or the controller with additional modules
(multisio D2-1T2RO, multisio D2-4RO, multisio D4-4RO ISO, multisio D2-4CI and
multimess D4) and individual capacitor stages, but the device is not assembled. In this
case, the controller is delivered with the default settings (refer to chapter Default settings)
and has thus not been precongured.
IMPORTANT SAFETY INFORMATION
CAUTION
The discharge times are automatically predened for the following programmed stage
powers. However, these must be checked and corrected if they dier from the capacitor
specications.
Capacitor power Discharge resistance Discharge time
2.5 kvar – 7.5 kvar 300 kOhm 60 seconds
10 kvar–17.5 kvar 300 kOhm 120 seconds
20 kvar and above 300 kOhm 180 seconds

Commissioning
3.1 Controller not congured
If a controller which has not been congured is to be started up, the following procedure
has to be performed step by step.
1. Conguration additional modules (multisio D2-1TI2RO,
multisio D2-4RO, multisio D4-4RO ISO, multisio D2-4CI and multimess D4)
If there are no additional temperature, relay or induced current measuring modules, this
step can be skipped. To congure additional modules, connect them and the supplied
bus line to the basic module. The additional modules can then be activated individually
using a scan mode, which has to be triggered via the basic module's operating panel
and the DIP switches or scan buttons on the additional module. If the compensation unit
consists of several cabinets, the correct cabinet assignment has to be set up.
Detailed instructions for this step are given in chapter Settings under Modules / Display
submenu.
2. Conguring current transformer values
All current transformer parameters need to be congured correctly for the compensation
controller to function properly. Primary and secondary current of the transformer have
to be set. These parameters can be found on the nameplate of the current transformer. In
addition, the phase allocation of the transformer needs to be congured correctly. In the
controller, the phase (L1, L2, L3) in which the current transformer is integrated has to be
set.
You can nd more detailed information on this topic in chapter Start-up under Transform-
er settings submenu.
3. Setting target cosine
You can ask your electricity supplier for the target cos, which should be set up at this
point. By default, the target cos is set to 0.95 inductive (see the "Default settings" chap-
ter).
You can nd more detailed information on this topic in chapter Start-up under Target
cosine submenu.
NOTE
Summer-CosPhi:
For a specied, adjustable time range, the target cosine can be altered, deviating from
the default settings (Menu item DST, Summer-target cosine). The setting range for the
time range goes from month 01 to month 12. beginning or ending with the 1st day of the

V7.00
24905_EDEBDA0272-5019-1_EN
19
month set. The setting range for the target cosine values is the same as the default target
cosine values (ind. 0.5 to cap.0.5).
The summer CosPhi cannot be activated in the Systems-Setting Generator (Power gener-
ation plants).
Setting under: Commissioning => target cosine => para => DST => CosPhi
4. Conguring the capacitor stages
There are two ways of conguring the capacitor stages. The stages can be congured
manually or using the auto conguration mode (a connected current measuring module
is required).
The most important setting to pay attention to is the stage power. The stage power can
be looked up on the nameplate of the stage or the circuit diagram and then programmed
manually. The auto conguration mode then automatically sets this value. However, it has
to be checked and conrmed after each time the auto conguration mode is applied.
Detailed instructions for the auto conguration mode are given
in chapter Extra ,Commissioning ,Stages ,Stage ,Auto conguration mode.
After the stage power has been congured, you have to set the detuning factor. This
factor can be read on the circuit diagram cover sheet or the nameplate of the stage.
If the compensation unit consists of several cabinets, the cabinet assignment should be
adjusted accordingly.
Detailed instructions for this step are given in chapter Start-up under Stages submenu.
5. Function test
A function test should be performed after all values have been programmed step by step,
by disconnecting the controller from the power supply for a few seconds.
The controller should start automatically after it is reconnected to the power supply. If the
cosφ voltage is read in the cosφ act. menu immediately after switching it on, the value
for cosφ should be low and inductive. After approx. 180 seconds, the controller starts to
switch on the individual capacitor stages.
The cosφ, which can be read in the cosφ act. menu, should have risen in comparison with
former values, or it should rise when switching on additional stages. If the compensation
system is designed correctly, the controller should compensate to the set target cos phi
after a while.
