3 Start-up guidelines 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 start-up procedure for the
multicomp D6-xxx-7 diers.
Case 1: You have bought a complete compensation system 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 D2-4CI and multimess D4) and individual
capacitor stages, but the system 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.

3.1 Controller not precongured
If an uncongured controller is to be started up, the following procedure has to be per-
formed step by step.
1. Conguring additional modules
(multisio D2-1T2RO, multisio D2-4RO, multisio D2-4CI and multimess 14)
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
For the compensation controller to function properly, all current transformer parameters
have to be set correctly. Primary and secondary current of the transformer have to be set.
These parameters can be read on the nameplate of the current transformer. In addition,
the phase assignment of the transformer has to be set 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 Transfor-
mer settings submenu.
3. Setting target cosine:
You can ask your energy supply company for the target cosine, which should be set up
at this point. The target cosine is by default set to 0.95 inductive (see chapter Default
settings).
You can nd more detailed information on this topic in chapter Start-up under Target
cosine submenu.

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 , Start-up
, 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
After all values have been programmed, a function test should be performed. To do so,
the controller has to be taken o the voltage supply for a few seconds.
After re-connecting it to the voltage supply, the controller has to start automatically. If
the cosφ voltage is read out 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 out in the cosφ act. Menu, should have risen compared to
previous values, or it should rise when switching on additional stages. If the compensati-
on unit is dimensioned correctly, the controller should compensate the set target cosine
after a certain period of time.

3.2 Controller not congured
If a controller already integrated into a KBR compensation unit by default should be used,
only the parameters of the current transformer have to be congured.
1. Conguring current transformer values
For the compensation controller to function properly, all current transformer parameters
have to be set correctly. Primary and secondary current of the transformer have to be set.
These parameters can be read on the nameplate of the current transformer. In addition,
the phase allocation of the transformer has to be set 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
Transformer settings submenu.
2. Function test
After all values have been programmed, a function test should be performed.
To do so, the controller has to be taken o the voltage supply for a few seconds.
After re-connecting it to the voltage supply, the controller has to start automatically. If
the cosφ voltage is read out 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 out in the cosφ act. menu, should have risen compared to
previous values, or it should rise when switching on additional stages. If the compensati-
on unit is dimensioned correctly, the controller should compensate the set target cosine
after a certain period of time.
