General safety notes
Failure to observe the following instructions may result in
serious injury or death!
There is a risk of electric shock during installation! Therefore, electrical devices
may only be installed, operated, serviced and maintained by qualified
professionals. A professional is someone who has the ability, experience and
knowledge required for the construction, installation and operation of
electrical equipment and who has been instructed in identification and
avoidance of possible hazards.
During installation and maintenance, the relevant regulations for the
installation of switchgear and accident prevention must be observed and
adhered to.
Devices with damaged or open housings or terminals must not be operated on
the power grid and must be disconnected immediately.
After disconnecting the device, 10 minutes must be waited until the capacitors
have been discharged. Subsequently, doors or covers may be removed. It must
be checked whether the disconnected area is voltage-free using a standardized
measuring instrument.
Ther BELUK GmbH assumes no responsibility or warranty for damage to
persons and equipment caused by improper installation and use.
Connection diagram: CX plus -12R
NOTE: The CX plus is designed to control capacitive or inductive stages.
Operating both stage types simultaneously is not possible.
Connection diagram: CX plus -12T
NOTE: The CX plus is designed to control capacitive or inductive stages.
Operating both stage types simultaneously is not possible.
Installation and commissioning
1) Before installation, the connection specifications of the CX plus must be
compared with the data of the power grid.
2) Disconnect the power supply and secured the working area against
unauthorized and unintentional reconnection. Check if the disconnected
area is voltage-free using a standardized measuring instrument. The
voltage-free system must be earthed and short-circuited. Neighboring live
parts must be covered and/or bypassed.
3) The current transformer must be short-circuited. A current transformer
which has not been short-circuited generates a life-threatening voltage.
This can lead to a destruction of the current transformer.
4) Insert the CX plus into the panel cut-out and fix it by using both fixing
clamps.
5) Connect the grounding cable to the intended terminal on the backside of
the device.
6) All cables must be connected as it is depicted in the connection diagram.
The terminal K of the current transformer must be connected to terminal
S1 and the terminal L to terminal S2.
7) Remove the short-circuit bridge at the current transformer.
8) The voltage can now be switched on.
9) If the device is connected correctly, the display will light up for one second
and all symbols will be displayed during a display test.
10) Now the First Setup can be started by confirming YES. The different
settings must be adjusted according to the power grid.
11) After a successful First Setup, the display shows AUTO. The control starts
after the set discharge time has been expired.
Frequently asked questions during commissioning
1) AUTO is not shown → control is switched off
Possible reasons: Manual operation activated; control is switched off;
temperature is too high; current is less than 5 mA; voltage or THD of the
voltage are inadmissible
2) U ALARM is shown → voltage is out of tolerance
Possible reasons: Nominal voltage (SETUP/Un) or voltage transformer
factor is set incorrectly (SETUP/Pt)
3) I Lo ALARM is shown → measuring current is smaller than 5 mA
Possible reasons: Connection from the current transformer to the
controller is incorrect; the current transformer jumper was not removed;
current transformer ratio is too large; no current flow
4) EXPORT is shown → reverse current flow
Possible reasons: If there is no real reverse current flow, the voltage or
current measurement is incorrect (phase, polarity)
5) Wrong cos ϕis shown → incorrect connection
Possible reasons: Voltage or current measurement is incorrect (phase,
polarity)
6) Outputs are immediately switched off
Possible reasons: Stage sizes in the stage database are incorrect
7) Frequent switching operations
Possible reasons: Capacitor capacity have not been recognized yet

Operation concept
1
Exit menu
Move cursor to the left
Reset alarm (push for 3 s)
2
Decrease value
Select next value, menu or stage
number
3
Increase value
Select previous value, menu item or
stage number
4
Open menu
Move cursor to the right
Accept value
Entering values
If a menu item has been entered, the first digit of the current value flashes.
Numbers can be increased or decreased by pushing the and keys.
The next digit can be selected by pushing the key. In order to select the
previous digit, the key must be pushed.
If the last digit (right) has been selected and the key is pushed again, a
multiplier k(kilo) or M(mega) can be set using the and keys. To accept
the value and complete the entry, the key must be pushed again.
If an entered value has not been accepted, or if another value is displayed after
an input, the entered value has exceeded or fallen below the threshold of the
setting range.
An entry can be canceled at any time by pushing the key. Depending on the
actual position, the key must be repeatedly pushed until the first digit (left)
is selected. Pushing the key again exits the menu item without accepting
changes.
