KBR multicomp F144-NC-1V1C6DO6RO-2 Functional principle
1 Functional principle of the controller
The multicomp F144-1V1C6DO6RO-2 hybrid controller has 12 outputs to control capaci-
tive 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 consumption of
the downstream system via measuring transformer inputs (A/D converter) and 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” ash-
ing on the LCD display. During this time, compensation to CosPhi 1.00 (output
CosPhi) is performed. To prevent alternating switching operations when switch-
ing between recovery and consumption, compensation to the output CosPhi is
performed for 15 minutes when recovery is detected.
The set target CosPhi is not activated until this time has elapsed.
The compensation power required for the target CosPhi is calculated continuously. If
the power dierence corresponds to the set hysteresis (switch on and o hysteresis), the
staged switching is performed in accordance with the compensation power required.
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 an optimum adjustment. Even for large
systems, sensitive controls may be set up with only a few modules. Stage ratios do not
have to be considered. After compensation, switching operations are interrupted for
a programmable time. In order to prevent alternating switching operations, the stage

KBR multicomp F144-NC-1V1C6DO6RO-2Functional principle
switch-o hysteresis can be increased to up to 150% of the lowest stage power.
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 characteristics can be kept.
For low load operation (secondary measuring current under the limit (<15 mA)), the
stages are switched o after 1 hour.
The programmed values are saved on an EEPROM and will thus not be lost after a mains
failure.
The measuring cycle of the controller for recording the necessary network parameters
takes approx. 20 ms.

Note
Limit for overvoltage switch-o = rated voltage + 10% (taking into account the
measuring voltage ratio). The value of 10% cannot be changed and serves to
protect the compensation system. The reset hysteresis is 1 % of the rated volt-
age.
In the event of an error, the compensation stages are switched o
and“overvoltage”is displayed.

3 Installation and electrical connection
of the system
3.1 General, highly important information
Tighten all screws and connections as otherwise the warranty will be
rendered void.
The device must be installed and operated in accordance with the applicable
VDE regulations (in particular VDE 0100) and the energy supplier regulations.
Connection cross-sections and fuse protection table: see attachment
3.2 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 capacitor and consumer currents must be determined. In case of an unbal-
anced phase load (in small operations), install the transformer in the phase with
the highest load.
P1 (K) to energy supply (indicated on the transformer).
P2 (L) to load outputs
S1 (k) with terminal k (controller terminal 20) and
S2 (l) with terminal l (controller terminal 21) should be connected in the com-
pensation system (use a two-color cable!).
Line cross section: up to 3 m =1.5 mm², up to 6 m =2.5 mm². For greater distanc-
es, we recommend using a 1 A transformer. The controller is designed for the
connection of 5 A and 1 A transformers; switching is set in the conguration.
If using existing transformers, the current paths always need to be connected in
series. The secondary transformer current needs to be at least 15 mA.
For lower currents, no capacitors will be connected (display shows“missing
current”). Measuring voltage connection according to the connection diagram.

3.3 Current transformer dimensions
The current transformer is designed based on the current consumption of the
consumers and not the capacitor current. If other measuring devices are con-
nected to a transformer in addition to the reactive power controller, the trans-
former power needs to be dimensioned accordingly. Losses also occur in the
current transformer line that need to be considered if there are large distances
between the transformer and the controller.

4 Starting up the system
4.1 General notes on starting up
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 be owing in the secondary circuit for the controller to be acti-
vated. Below this limit, the display will show“missing transformer current”.
Check the transformer connection (transformer ratio too high?).
The measuring voltage has to be correct before switching on the controller.
No error message is displayed, but the learning mode cannot be started.
If stage power has been programmed, the power factor CosPhi has to be
displayed after initialization. Normally, when no capacitors are connected,
CosPhi lies in the range of 0.6 to 0.9 inductive, (e.g. CosPhi 0.80 ind).
If a capacitive value is displayed or if the“G”symbol is ashing, the phase al-
location of current and voltage measurement is incorrect (provided that there
is no generator operation at the time). In the Commissioning programming
menu, the phase allocation can be changed using the rotary eld U and rotary
eld I functions.
The rst switching operation may take up to 10 seconds. The thyristor stages
are switched in a set milliseconds interval until compensation. If the existing
thyristor stages are not sucient, additional contactor stages are switched on.
The CosPhi displayed has to approximately reach the target CosPhi.
Note
The learning process is started in the Commissioning menu,
in the Activate learning mode submenu.

KBR multicomp F144-NC-1V1C6DO6RO-2Commissioning
4.2 Compensation system with controller
The controller is preset as a component of a compensation system (refer to the
connection diagram of the compensation system). The following need to be
programmed or checked:
Target CosPhi according to energy supplier regulations.
Primary and secondary current in the main circuit according to the mounted
transformer.
If required, set the measuring voltage transformer data.
If no stage powers have been programmed, the controller will switch to the
Commissioning menu. Subsequently, the stage power can be programmed in
the settings menu, or using the learning process.
The programmed values are saved on an EEPROM and will thus not be lost
after a mains failure.
