Safety notes
Read these safety notes and instructions attentively and carefully first. Familiarise yourself with the
device prior to installation, commissioning and operation. The following symbols are used in the manual
and on the device label on the back of the device in order to indicate dangers and problems or to give
specific instructions.
!DANGER
DANGER indicates a dangerous situation which, if not avoided, may cause death or severe injuries.
!WARNING
WARNING indicates a dangerous situation which, if not avoided, may cause death or severe
injuries.
!CAUTION
CAUTION indicates circumstances which may damage or destroy the device in case of non-
observance, but do not cause injuries.
NOTE: Further information in order to describe special technical features in a more detailed way.
!DANGER
During the installation of the CX plus, there is a risk of electric shock. For this reason, installation,
commissioning and maintenance may exclusively be performed by a skilled electrician with the
necessary qualification. A skilled electrician is a person who has the ability, experience and
knowledge necessary for the construction, installation and operation of electrical equipment and
systems and who is trained in the detection and prevention of potential hazards.
During installation, the relevant regulations for the installation of switchgear and for the prevention
of accidents must be observed and complied with. Devices with damaged or open housing or
terminals may not be connected to the mains and must be disconnected immediately.
The current transformer must be short-circuited prior to disconnecting the current measurement path
at the device resp. at the current transformer. Otherwise, there may be a life-threatening voltage at
the connections of the current measurement path resp. of the transformer. In the long run, the
transformer will be destroyed by the high voltage.

7
Installation and commissioning
1) Before installation, the connection data of the CX plus must be compared with the data of the
supply network and of the installation.
2) The working RANGE must be disconnected from voltage and secured against unauthorised and
unintentional restart. The absence of voltage must be verified with a standardised instrument /
testing device. The voltage-free system must be grounded and short-circuited. Adjacent live
parts must be covered and / or placed behind barriers.
3) The current transformer must be short-circuited. A current transformer that has NOT been short-
circuited generates very high voltages posing a danger to persons and equipment. The current
transformer can thereby be destroyed.
4) Disconnect and remove the old reactive power controller.
5) Plug the CX plus into the switch panel section and fix it with the two mounting brackets. (Section
138 x 138 mm).
6) Connect the protective conductor at the PE terminal of the metal back of the CX plus.
7) Connect the connecting lines as per the wiring diagram (current transformer: K to power plant,
L to load).
8) Remove the current transformer jumper.
9) Switch on voltage.
10) With a proper connection and correct connection data, the display lights and all symbols are
visualised on the LCD in the course of a display test for 1 second.
11) The current transformer factor must be entered.
12) If necessary, also enter the correct nominal voltage and the voltage transformer factor.
13) Execute the “Automatic initialisation”(AI).
14) If the “Automatic initialisation”was successfully finished, the message AUTO appears on the
display. Control starts after the discharge time lock (default: 75 s).

Commissioning
The CX plus is pre-programmed with default values, which enable an operation almost without
further settings, if connected to a 400 V supply network according to the wiring diagram.
The measurement values of current and power are only displayed, if the current transformer
factor has been set.
NOTE: If the connection of measuring voltage and current results in a phase between voltage
and current not equal to 0° resp. 90°, execute the Automatic Initialisation (AI) first or manually
set the phase correction angle (setup menu: 206) correctly. A table with the phase correction
angles, in dependence of the connection, can be found in the Annex Setting of phase
correction angles.
NOTE: The “Automatic Initialisation”only identifies the correct phase between measuring
voltage and current. Furthermore, the AI determines which switching outputs are occupied and
which not. Switching outputs which are not occupied are set to the stage type “FOFF”. The
stage sizes are determined at first by the control in normal control mode.
After applying the mains voltage, the message “AUTO”appears on the display and the
currently measured COS is displayed, if measuring voltage and current are within the
tolerance. Normally, the COS should be inductive (display of a small ibehind the first line).
From this moment on, the discharge time lock of the capacitors is active (factory setting: 75
sec.). After the discharge time lock, the CX plus starts controlling. In the process, the stage
sizes are determined automatically. Stage outputs which are not occupied are set to the stage
type “FOFF”(Fix-Off), if the first three switching processes have been unsuccessful. I.e. the
control ignores these stages.
!CAUTION
Exception: The current transformer factor (SETUP/Ct) must be entered in order to correctly calculate
the measurement values and to correctly identify the stage sizes.

11
Questions during commissioning
1. “AUTO”is not displayed control stopped or switched off.
Possible causes:
Manual operation, control has been stopped or switched off in the setup menu.
Current is less than 5 mA, voltage of THD of voltage or current are out of tolerance, temperature is too
high, “Automatic initialisation (AI)”was cancelled with an error notification.
Control is switched off
2. Display “U ALARM”measuring voltage out of tolerance
Possible causes:
Over- or under-voltage in the system, the set nominal voltage and the voltage transformer factor do not
correspond to the system.
Solution:
Check the settings for nominal voltage (SETUP/100/Un) and voltage transformer
(SETUP/100/Pt). The set voltage tolerance range is too small.
Solution:
Check the settings of the tolerance range (SETUP/204).
3. Display “I Lo ALARM”no current
Possible causes:
Connection from the current transformer to the controller is not correct; current transformer jumper is
not removed; transformation ratio of the transformer is too large current is less than 5 mA no
current
4. Display “EXPORT”feeding back of active power
There is no real feeding back, please check the connection of measuring voltage and current (phase,
polarity).
Possible causes:
The set phase correction angle does not correspond to the connection of measuring voltage and current.
Solution:
Correct the connection, execute the “Automatic initialisation (AI)”or manually set the phase
correction angle correctly.

12
Measuring voltage or current has been connected at a twisted angle of 180° from the direction of
connection (U2 / U1 instead of U1 / U2 resp. S2 / S1 instead of S1 / S2).
Solution:
Correct the connection, execute the “Automatic initialisation (AI)”or add 180° to resp. subtract
180° from the set phase correction angle (SETUP/206) (new angle < 360°).
Please observe the separate notes at the end of the chapter for the setting of the phase
correction angle.
Also see chapter “Automatic initialisation“
5. Incorrect “COS PHI”is displayed incorrect connection
Incorrect phase between measuring voltage and current. Please check the connection of measuring
voltage and current (phase, polarity).
Possible causes:
The set phase correction angle does not correspond to the connection of measuring voltage and current.
Solution:
Correct the connection, execute the “Automatic initialisation (AI)”or manually set the phase
correction angle correctly.
Measuring voltage or current has been connected at a twisted angle of 180° from the direction of
connection (U2 / U1 instead of U1 / U2 resp. S2 / S1 instead of S1 / S2).
Solution:
Correct the connection, execute the “Automatic initialisation (AI)”or add 180° to resp. subtract
180° from the set phase correction angle (SETUP/206) (new angle < 360°).
Please observe the separate notes at the end of the chapter for the setting of the phase
correction angle.
Also see chapter “Automatic initialisation“
6. Display “AI Abrt”The “Automatic initialisation”(AI) was cancelled with error.
Possible causes:
Heavy load fluctuations during the “Automatic initialisation (AI)”
Solution:
Restart the “Automatic initialisation (AI)”, when the mains is steadier. The measuring current
was too small.
The current transformer ratio may be too large.
Solution:
Check if the selected current transformer corresponds to the system and change it, if necessary.
Restart the “Automatic initialisation (AI)”.
The stage sizes are too small.
Solution:
Enter the phase correction angle (SETUP/206) manually and switch on the control again
(SETUP/100/PFC or SETUP/310).
If the “Automatic initialisation”(AI) is not successful after further attempts, it is also possible to
set the correct phase correction angle (SETUP/206) manually. The stage outputs which are not
connected can be set manually (SETUP/100/OUt) to the stage type “FOFF”.
The control must be manually switched on again (SETUP/100/PFC or SETUP/310).

13
7. Stage outputs are immediately switched off again.
Possible causes:
The nominal value of a stage saved in the stage database is not correct anymore (after changing a
capacitor, the value must be entered manually again or the entire stage database must be reset).
Stage is defective no stage power identified during switching
Solution:
Check the fuses and power contactors (see chapter Stage recognition / defective stages).
8. One or several stages were identified as defective. No stage power identified during switching.
Possible causes:
Stages are defective
Solution:
Change the capacitors
Fuses are defective
Solution:
Change the fuses
Power contactor does not switch anymore or contacts are defective.
Solution:
Change the power contactor (see chapter “Recognition / resetting defective stages”)
9. Frequent switching of the outputs
Possible causes:
The initial values of the stage power of the individual stages are still saved in the stage database. By
switching the stages, the stage powers of the individual capacitors are identified and saved in the stage
database.
10. Identified stage sizes are incorrect
Possible causes:
The set current transformer factor is incorrect

14
Solution:
Enter the current transformer factor correctly (SETUP/100/Ct), enter the stage sizes manually
(SETUP/402) or reset the stage database (SETUP/602).
Heavy load fluctuations during the stage identification
Solution:
Enter the stage sizes manually (SETUP/402) or reset the stage database (SETUP/602).
The set phase correction angle does not correspond to the connection of measuring voltage and current.
Solution:
Correct the connection, execute the automatic initialisation or manually set the phase correction
angle correctly.
11. Measurement values of current and power are not displayed.
Possible causes:
The current transformer factor was not set.
Solution:
Enter the current transformer factor correctly (SETUP/100/Ct).
12. Measurement values of current, power and stage sizes are incorrect.
Possible causes:
The set current transformer factor is incorrect.
Solution:
Enter the current transformer factor correctly (SETUP/100/Ct), enter the stage sizes manually
(SETUP/402) or reset the stage database (SETUP/602).
! WARNING
Prior to disconnecting the current measurement path at the device resp. at the current transformer,
the current transformer must be short-circuited. Otherwise, there may be a life-threatening voltage
at the connections of the current measurement path resp. of the transformer. In the long run, the
transformer will be destroyed by the high voltage.
NOTE: In order to set the phase correction angle:
A table with the phase correction angles, in dependence of the connection, can be found in the Annex
Setting of phase correction angles.
If the adding of 180° results in a phase angle equal to or greater than 360°, subtract 180° instead.
Example:
Previously set phase correction angle = 270°
270° + 180° = 450° greater than 360°
270° - 180° = 90° phase correction angle to be set

Operation of the controller
The CX plus is operated using 4 keys.
Increase values, select the previous
measurement value, menu item and stage
number
Exit menus,
moves the cursor to the
left,
reset alarms (keep the key
pressed for approx. 3 s in
order to reset the alarm)
Open menus,
moves the cursor to the
right,
accept the set value
Reduce values, select the next measurement
value, menu item and stage number
Entering numerical values:
Since the procedure for entering the numerical values is always the same, the input mask is described
now:
The current value is shown on the display, while the first digit is flashing. By pressing the keys “”and
“”, this digit can be increased or decreased.
The next digit can be selected by pressing the key “”. As before, the keys “”and “” can be used to
select the desired value. To select the previous digit again, the key “” is used. The desired value is set
with the keys “”and “”.
Pressing the key “” at the last digit (right), an additional multiplier k (kilo) or m (mega) can be chosen
with the keys “”and “”. In order to accept the value and to finish the entry, the key “”has to be
pressed again.
If a set value was not accepted or if another value is displayed after the entry, it is possible that the set
value exceeds the limit of the setting range.
The entry may be cancelled with the key “”: Press the key “”until the first digit (on the left) is
selected. The entry is cancelled without accepting the new value by pressing the key “”again.
NOTE: If no key is pressed within 60 s, the backlighting is turned off. To turn the backlight on, one of
the 4 keys has to be pressed. Afterwards, the usual key actions are available.
