1 Controller functional principle
The controller's micro processor acquires the supply voltage and the current consumption of the downstream
facility via measuring transformer inputs (A/D transformer) and calculates the active and reactive power ratios
of the network. The controller operates based on a 4 quadrant operation.
• Energy recovery in generator operation is recognized and displayed (the LCD shows a flashing
„G”). During this time, compensation to CosPhi 1.00 (recovery CosPhi) will be performed. To avoid
alternating switching operations when switching between recovery and consumption,
compensation to the recovery CosPhi is performed for 15 minutes when recovery is detected.
During this period of time, the set target-CosPhi is disabled.
The compensation power required for the target CosPhi is calculated continuously. If the power difference
corresponds to the set hysteresis (switch on and off hysteresis), the staged switching is performed in
accordance with the compensation power required. Manually switched stages, however, are not included in the
optimization. In case of identical stages with identical power, the stage disconnected for the longest time is
connected.
With only a few switching operations an optimal adjustment is obtained. Even for large facilities, sensitive
controls may be set up with only a few modules. No stage ratios need to be considered. After compensation,
switching operations are interrupted for a programmable time. In order to avoid alternating switching
operations, the stage switch off hysteresis can be increased to up to 150% of the lowest stage power.
For light load operation (secondary measurement current under the limit (< 20mA), the stages are switched off
after 1 hour.
The programmed values are saved on an EEPROM and will thus not be lost after a network failure.
The measuring cycle of the controller for recording the necessary network parameters takes approx. 20 ms.
In case of failure, the compensation stages are switched off and "overvoltage" is displayed.
bNote!
Limiting value for overvoltage switch-off = nominal voltage + 10%
(taking into account the measurement voltage transformer ratio).
The value of 10% is unchangeable and serves the safety of the
compensation facility
The reset hysteresis is 1% of the rated voltage.

3 Mounting and electrical connection of the device
3.1 General, very important!
• Tighten all screws and connections as otherwise warranty will be void!
• The device needs to be installed and operated in accordance with valid VDE regulations
(in particular VDE 0100) and energy supplier regulations.
Connection cross-sections and fuse protection table: see attachment
3.2 Current transformer connection and measurement voltage
If possible, mount the transformer in the phase that corresponds to L1 of the compensation facility
(determine by means of voltage measurement). All capacitor and consumer currents need to be
determined. In case of unbalanced phase load (small facilities), install the transformer in the phase with
the highest load.
- P1 (K) to energy supply (indicated on the transformer).
- P2 (L) to load
- S1 (k) with terminal k(controller terminal 20) and
- S2 (l) with terminal l(controller terminal 21) needs to be connected in the compensation facility
(use two-color cable!).
Line cross-section: up to 3 m = 1.5 mm², up to 6 m = 2.5 mm². For greater distances, 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 configuration.
If using existing transformers, the current paths always need to be connected in series.
The secondary transformer current needs to be at least 12 mA. For smaller currents, no capacitors will
be connected (display shows “missing current“).
Measurement voltage connection according to connection chart.
3.3 Current transformer dimensions
The current transformer is dimensioned based on the current consumption of the consumers and not the
capacitor current. If other measuring devices are connected to a transformer in addition to the reactive power
controller, the transformer power needs to be dimensioned accordingly. Also, losses occur in the current
transformer line that need to be considered in case of large distances between the transformer and the
controller.

4 Commissioning the facility
4.1 General commissioning notes
• Switch on a sufficient number of inductive consumers (e.g. motors) prior to switching on the compensation
facility. A transformer current of at least 15 mA needs to flow in the secondary circuit for the controller to be
activated. Below this limit the display will show “missing transformer current”.
• The transformer connection needs to be checked (transformer ratio too high?).
• Before switching on the controller, measurement voltage must be available.
No error message is displayed, but the learning mode cannot be started.
• If stage power has been programmed, the power factor CosPhi should be displayed after initialization.
Normally, when no capacitors are connected, CosPhi is in the range of 0.6 to 09. inductive,
(e.g. CosPhi 0.80 ind).
• If a capacitive value is displayed, or if there is a flashing G symbol, the phase allocation of current and
voltage measurement is incorrect. In the Commissioning programming menu, the phase allocation can be
changed using the function Rot.field U and Rot.field I (provided that there is no generator operation at the
time).
• The first switching operation may take up to 60 seconds. The stages are switched in a set 1 second
interval until compensation. The CosPhi displayed has to converge target CosPhi.
4.2 Compensation facility with controller
The controller is preset as a component of a compensation facility (refer to connection diagram of
compensation facility). 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 measurement voltage transformer data.
• If no stage power has been programmed, the controller will switch into the Commissioning menu.
Subsequently, stage power programming can be performed 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 network failure.
bNote!
The learning process is started in the Commissioning menu,
in the Activate learning mode submenu.

Configuring current transformer values:
For the compensation controller to function properly, all parameters concerning the current transformer have
to be set correctly. Primary and secondary current of the transformer have to be set (submenu Iprim. / Isec.).
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 (submenu Rot.field I). If the transformer connections are mixed up
(k and l interchanged), this can be corrected with the setting -L1, -L2 and -L3.
Setting target CosPhi:
You can ask your energy supply company for the target CosPhi, which should be set up at this point.
The target CosPhi is by default set to 0.95 inductive (see chapter Default settings).
Setting the voltage transformer parameters:
Specify the primary voltage in the U primary submenu, the secondary voltage under U secondary and the
phase allocation of the measurement voltage under Rot.field U. These settings apply to a standard network
(voltage Ph-Ph: 400V primary, 400V secondary). With measurement voltages of over 500V, the parameters
specified on the voltage transformer have to be configured, e.g. 690V / 100V, as well as the measuring mode,
e.g. L12 for the measurement voltage connection between the phases L1 and L2.
Setting the discharge time:
Checking or, if required, changing the discharge time of the capacitor stages is a very important menu item.
Possible discharge times are 0, 3, 30, 60, 300, 600, 900 sec. Please make sure that the correct value is set,
otherwise the capacitors could be damaged.
Configuring the capacitor stages:
There are two ways of configuring the capacitor stages: The stages can be configured manually or using the
learning mode.
It is important to set the stage power correctly. The stage power can be looked up on the nameplate of the
stage or the circuit diagram and then programmed manually. In thiscase, skip the menu itemActivate learning
mode and individually enter the power value vor each stage.
If you want to Activate the learning mode, you have to make sure thatall previous submenu parameters have
been set correctly.
The learning mode is activated by pressing the button U. Change to Yes with the button Vand confirm with
button X.
The learning mode automatically sets the stage power. However, this value has to be checked after each time
the learning process is performed.
aCaution!
If there is no measurement voltage, the learning mode menu does not
appear.
