plate.
A faulty connection may result in the destruction of the device!
When connecting the device, ensure that the data given in the connection
chart is complied with (see "Connection diagram") and that the connection
cables are not live. When wiring, always ensure that all wiring material used is
neither damaged nor defective and that the polarity is correct!
In order to ensure proper and safe product operation, ensure that the device is
transported, stored, installed and assembled and carefully operated and main-
tained in accordance with the specications.
If the device is visibly damaged it should generally be considered unsuitable
for use and disconnected from the power supply. Troubleshooting, repairs and
maintenance work may only be carried out in our facilities or after contacting
our service team.
Unauthorized opening of the the device will render your warranty null and
void. Correct operation can no longer be guaranteed!
Opening the device may expose live parts. Capacitors in the device may still be
charged, even if the device has been disconnected from all power sources. Do

KBR multicomp F144-3 6DO/6RO Functional principle
1 Functional principle of the controller
The multicomp F144-1V1C6DO6RO-3 hybrid controller has 12 outputs to
control capacitive compensation stages. Outputs 1 to 6 are designed to control
thyristor modules (by optocoupler outputs) and outputs 7 to 12 to control
capacitor contactors (by oating relay contacts).
To make optimal use of the thyristor modules' or capacitor contactor modules'
switching performance, you can set the following parameters separately:
for thyristor stages
Switching interval 50 to 9999 milliseconds
Discharge time 20 to 9999 milliseconds
Idle time 20 to 9999 milliseconds
for contactor stages
Switching interval 0 to 10 seconds
Discharge time 0 to 900 seconds
Idle time 0 to 300 seconds
The controller's microprocessor records the mains voltage and current con-
sumption of the entire plant by measuring transformer inputs (A/D converter)
and, on the basis of this, calculates the active and reactive power ratio of the
power supply. The controller operates in four quadrants.
Energy recovery in generator operation is detected and indicated by a "G"
ashing on the LCD display. While in generator operation, compensation to
cos phi 1.00 (output cos phi) is performed. To prevent alternating switching
operations, this target cos phi is maintained for 15 minutes after generator
operation ends.
The compensated power required for the target cos phi is calculated contin-
uously. If the power dierence corresponds to the set hysteresis (switch-on
and switch-o hysteresis), the stages are switched depending on the required
compensation power. Manually switched stages are, however, not included in
the optimization. In case of identical stages with identical power, the stage that
has been switched o for the longest time is switched on.
Having fewer switching operations results in optimum adjustment. Even for
large systems, sensitive controls can be set up with just a few modules. Stage
ratios do not need to be considered. After compensation, switching operations
are interrupted for a congurable time. To prevent alternating switching opera-
tions, you can increase the stage switch-o delay by up to 150% of the smallest
stage's power.
In light load operation (secondary measuring current under the limit), the stag-
es are switched o after the set delay time.

KBR multicomp F144-3 6DO/6RO
After an adaption time of 60 seconds, the thyristor stages are switched by
contactor stages of the same size. This guarantees that the fast control charac-
teristics can be kept.
The integrated temperature measurement input monitors the temperature in
the reactive power compensation system and causes the fan to be switched on
if a predened temperature threshold is exceeded and switched o again when
the temperature drops below the reset temperature.
To prevent the fan from switching unnecessarily often, it has a run-on time
of 30 minutes. You can switch the fan (relay output 12) on or o permanently
using the "Stage status" menu. If you select "Auto", the fan output is controlled
by the temperature measuring input.
You can also protect the system by dening a switch-o temperature. This
makes it possible to switch stages o in time if there is a risk of damage due
to overheating. Once the temperature drops below the reset temperature, the
stages are switched on again one after the other.
The settings are saved on an EEPROM so that they are not lost in the event of a
power failure.
The measuring cycle of the controller used to record the necessary network
parameters takes approx. 20 ms.
NOTE
Limit for overvoltage switch-o = measuring voltage + 10% (taking the mea-
suring voltage ratio into account). This value cannot be changed and serves to
protect the compensation system.
In the event of an error, the compensation stages are switched o and "Over-
voltage" is displayed.

CAUTION!
The discharge times are automatically predened, in the capacitor contactor
stage, 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
0.1 kvar – 9.9 kvar 300 kOhm 60 seconds
10 kvar – 19.9 kvar 300 kOhm 120 seconds
20 kvar and above 300 kOhm 180 seconds
In the thyristor stages, irrespective of the stage power, the discharge time is al-
ways entered as 20milliseconds, both when reprogramming and when chang-
ing the stage power. A discharge time changed later on is retained however, as
long as the stage power is not changed.

4 Installation and electrical connection of
the system
4.1 General, very important information
Tighten all screws and connections. Failure to do so will void the warranty.
Install and operate the device in accordance with the applicable VDE regula-
tions (in particular VDE 0100) and the electricity supplier's regulations.
Connection cross-sections and fuse protection table: see annex.
CAUTION!
Failure to observe the connection conditions or exceeding the permissible
voltage range may result in damage or destruction of the device.
Before connecting the power supply to the device, please note:
The voltage and frequency must comply with the specications on the name-
plate. Observe the limits specied in this manual!
The electrical installation of the building must have a circuit-breaker or fuse
for the power supply voltage, in accordance with the applicable local regula-
tions.
Install an isolating switch that is easily accessible to the user and close to the
device. It must be marked as an isolating switch for this device.
Install a suitable, correspondingly marked fuse and isolating switch for the
voltage measurement inputs nearby (or, alternatively, a circuit breaker). These
voltages are hazardous live!
Voltages that exceed the permissible rated voltages must be connected via a
voltage transformer.
Measuring voltages and measuring currents must come from the same net-
work.

4.2 Current transformer connection and measuring voltage
If possible, mount the transformer in the phase that corresponds to L1 of the
compensation system (determine by means of voltage measurement). All ca-
pacitor and consumer currents must be determined. In case of an unbalanced
phase load (in small companies), install the transformer in the phase with the
highest load.
P1 (K) to energy supply (indicated on the transformer).
P2 (L) to load outputs
Connect S1 (k) with terminal k (controller terminal 20) and
S2 (l) to terminal l (controller terminal 21) in the compensation system
(use a two-color cable!).
Wire cross section: up to 3 m =1.5mm², up to 6m =2.5mm². For longer dis-
tances, we recommend using a 1 A transformer. The controller is designed for
connection to 5 A and 1 A transformers; switching is done by rmware.
If you use existing transformers, the current paths must always be connected in
series. The secondary transformer current needs to be at least 15 mA. For lower
currents, no capacitors are connected ("No measuring current" is displayed).
Connect the measuring voltage in accordance with the connection diagram.
4.3 Current transformer dimensions
The current transformer is designed on the basis of the current consumption of
the consumers, not the capacitor current. If, in addition to the reactive power
controller, other measuring devices are connected to the same transformer, the
transformer power needs to be chosen accordingly. If the transformer and the
controller are far apart, losses also occur in the current transformer cable, which
need to be taken into consideration.
4.4 Standard connection diagrams
NOTE
The stage outputs 1 to 6 are optocoupler outputs.
External voltage supply Terminal input 40 max. 30 VDC
(rated voltage 24 VDC), max. 35mA.

5 Commissioning the system
5.1 General notes on commissioning
The controller is congured as a compensation system component (see con-
nection diagram) by default. The following settings need to be congured or
checked:
Target cos phi according to the energy supplier's specications.
Primary and secondary current in the main circuit in accordance with the
mounted transformer.
Set the measuring voltage transformer data, if necessary.
If no stage powers have been congured, the controller will switch to the
Commissioning menu after initialization. Next, stage power programming can
be performed in the settings menu, or using the learning process.
NOTE
You can start the learning process from the "Learning mode activate" submenu
in the Commissioning menu, using the Enter/Input buttons.
If the "Learning mode" window does not open, please check that
Menu on is set for "Learning mode" in the "Extras" menu.
The settings are saved on an EEPROM so that they are not lost in the event of
a power failure.
Switch on a sucient number of inductive consumers (e.g. motors) before
switching the compensation system on. A transformer current of at least 15
mA needs to ow in the secondary circuit for the controller to be activated.
Below this limit, the error message "No transformer current" will be displayed.
Check the transformer connection (is the transformer ratio too high?).
If all connection conditions are OK, the instantaneous power factor cos phi
should be displayed after initialization, e.g. normally, when no capacitors are
connected, cos phi is between 0.6 and 0.9 inductive, (e.g. cos phi 0.80 ind).
If a capacitive value is displayed, or if the "G" symbol is ashing, the phase
allocation of the current and voltage measurement is incorrect.
