Product descriptionIntended useThe reactive power controller DynamicC together withexternal capacitor stages, serves for step by step con-trolling of the phase shift angle cos(phi) in 50/60Hzlow voltage networks. Depending on the type of thereactive power controllers DynamiC , contactors or semiconductor switches can be controlled directly.Additionally, the following electrical quantities are meas-ured and indicated:- Voltage L2-L3,- Current in L1,- Frequency,- Sum real power (Consumption/supply),- Sum reactive power (ind./cap.),- uneven current harmonic waves 1. - 19. in %,- uneven voltage harmonic waves 1. - 19. in %.The harmonic contents are related to the rated voltageor rated current.

The connection is carried out on the back side via touchproof spring power terminals.Measurement and supply voltage are taken from themeasurement voltage and must be connected to thebuilding installation via a separation (switch or powerswitch) and an overcurrent protection (6,3A).The current measurement is carried out via a ../5A or../1A current transformer in one outer conductor.

The relay outputs are suitable for contactor control, thetransistor outputs are provided for the control of fastswitching thyristor modules, switching at zero crossing.

Hints for maintenanceBefore delivery the device is tested in various safetychecks and marked with a seal. If the device is opened,these checks must be repeated.There is no guarantee for devices, which are openedout of the manufacturing works.

Repairing and calibrationRepairing and calibration work can be carried out in themanufacturing works only.

Front foilThe cleaning of the front foil must be done with a softcloth using a common cleansing agent. Acid or acidicagents may not be used for cleaning.

Waste managementThe device can be disposed as electronical waste ac-cording to the legal regulations and recycled.

Data protectionThe data protection is carried out in a none volatilememory (EEPROM).Changed programming data are saved immediately.

= Key 1 = Key 2 = Key 3


Switching of capacitor stagesDynamiC calculates the required reactive power toreach the set target-cos(phi) from the current from oneouter conductor and the voltage between two outer con-ductors. If the cos(phi) deviates from target cos(phi),external capacitor stages or transistor outputs areswitched on or off.In automatic mode the capacitor stages are switched inor off, when the required reactive power is higher orequal to the smallest stage power.If the power of the first capacitor stage is three times ashigh as the measured real power, all capacitor stagesare switched off.

Switching outputsDepending on the variety of DynamiC , relay ortransistor outputs serve as switching outputs.The relay outputs are suitable for controlling contactorsand the transistor outputs can switch thyristor modules,that switch in zero crossing of voltage.For relay outputs the time between two connections ordisconnections is set to two seconds. Transistor outputshave no limitation of the switching period.

Net returnAfter net return, the set discharge time runs for therelay outputs. The transistor outputs do not mention thedischarge time.

Funktional descriptionMeasurementThe measurement is suited for 3 phase systems with orwithout neutral conductor for frequencies of 50Hz or60Hz. The electronical measurement system records anddigitalizes the effective values of voltage between L2and L3 (L-N Option) and the current in L1.In each second several snap check measurements arecarried out. As the current is only measured in oneouter conductor, and the voltage only between two outerconductors, the measured values, which are related toall three outer conductors, are exact for equal loadedouter conductors only.The following electrical quantities are calculated:

Current and current harmonicsVoltage and voltage harmonicsReal power, sumApparent power,sumReactive power, sumReactive power for each stageReactive current for each stageCos(phi),Net frequency.

The following information can be indicated:Number of switchings of each stage,total connection time of each stage andthe inner temperature.

DynamiC measures the frequency of the measurementand supply voltage and shows the average over 10 sec-onds.

Hints for installationMounting placeThe reactive power controller DynamiC is suited formounting and operation in reactive power compensationsystems.

The connection is carried out on the back side via touchproof spring power terminals.

Measurement and supply voltageThe measurement is suited for 3 phase systems with orwithout neutral conductor. Measurement and supplyvoltage are taken from the measurement voltage andmust be connected to the building installation via aseparation (switch or power switch) and an overcurrentprotection (2A...10A).

The reactive power controller measures and supervisesthe voltage between two outer conductors. If one ofthose two fails, the reactive power controller gets nomore measurement and operating voltage, and switcheson the capacitive stages after net return according tothe programmed times.If the third outer conductor is missing, this will not berecognized by the reactive power controller. If the con-tactors are supplied by this outer conductor, the contac-tors can attract simultaneously and without considera-tion of the discharge time after net return.Falsch

Current measurementThe current transformer is connected to the clamps kand l (/5A or /1A) from the outer conductor L1.Please ensure during the installation of the current trans-former, that the current transformer is passed by theconsumer current but not by the compensation current.The current can be measured by an Amperemeter tocompare it with the current indicated by DynamiC tocheck. Please note, that the factory's presettings of thecurrent transformer ratio is set to 10 and must be adaptedto the existing current transformer.If you should short-circuit the current transformer, theindicated value on DynamiC must decrease to 0A.

Examples for the setting of the current transformerExample 1Current transformer 200A/5ASet DynamiC to 40

Example 2Current transformer 500A/1ASet DynamiC to 500

Example 3Sum current transformer 1000A+1000A/1ASet DynamiC to 2000

Attention!For unequal load of the outer conductors, thecurrent should be measured in the outer con-ductor, which is loaded most heavily.

Real powerIf current and voltage are connected to DynamiC ac-cording to the connection diagram, a positive real poweris displayed in case of real power consumption. Realpower with a negative sign in the indication points tothe supply of real power or an error of connection.Possible error:- Voltage and current are measured in the wrong outerconductor.- The current transformer clamps (k-l) are exchanged.

Switching outputsThe reactive power controller DynamiC can beequipped with up to 12 switching outputs. Theswitching outputs can be equipped either with relay ortransistor outputs. If a device is equipped with relay ortransistor outputs it is not shown on display. Theequipment can be seen in the connection diagram onthe back of DynamiC .

Relay outputsCapacitor contactors can be connected to the relay out-puts according to the connection example "Relay out-puts".

Transistor outputsSemi conductor switches, switching at zero crossing,must be connected to the transistor outputs of the reac-tive power controller.The transistor outputs switch the voltage of an externald.c. net supply to the semiconductor switches.

Check switching outputsPlease switch in the capacitor stages in manual mode:The inductive reactive power is decreased by the powerof the respective capacitor stage.Please switch off the capacitor stages in manual mode:The inductive reactive power is increased by the powerof the respective capacitor stage.

Possibility of errors:The outputs do not switch

- Relay output defective.- Transistor output defective.

The change of the reactive power is faulty- The current is measured incorrectly.- A wrong current transformer ratio is set.- The current is measured in the wrong outerconductor.- The voltage is measured in the wrong outerconductors.- The current transformer clamps k-l are exchanged.

The reactive power does not change- The current transformer is installed at the wrongplace.- Switching outputs faulty.- The wrong control voltage is connected to theswitching outputs.

RS485 Interface (Option)Transmission protocolsTwo transmission protocols are available for the connec-tion to an existing field bus system:

0 - Modbus RTU (Slave) and1 - Profibus DP V0 (Slave) .

With Modbus protocol you can have access to the data oftable 1, and with Profibus protocol you can have accessto the data of table 2.

Bus structureAll devices are connected in bus structure (line). In onesegment up to 32 participiants can be assembled. At theend and the beginning of each segment, the cable mustbe terminated by resistors. In DynamiC you can activatethese resistors with two plug-ins.For more than 32 participiants you must use a repeater(line amplifier) to connect the single segments.

ShieldingFor connections via RS485 interface, you need a pro-tected and twisted cable. To achieve a sufficient protec-tion result, the shielding must be connected at both endsextensively to the housing or parts of the cabinet.

Cable specificationsThe maximum cable length depends on cable type andtransmission speed. We recommend cable type A.

Learning of the configurationAfter installation of thecontroller there is thepossibility to learn andsave the configurationwith the function"learn".

Important requirements are:- The discharge time for capacitors is set to 60 seconds,when the device is delivered. For capacitors with longerdischarge times, the discharge time must be checkedand changed before using the "learn" function.- The current transformer must be flown through byconsumer and compensation current.- The measurement and supply voltage may not be takenfrom phase to N.- The compensation system must be ready for opera-tion.

The learning function of the controller is devided intotwo steps:Step 1 - Learning of the connection configurationHere the correction angle between current transformerand measurement and supply voltage is detected.Step 2 - Learning of the capacitor stagesHere the number of outputs and the stage power ofeach stage is detected.The following requirements are neccessary:- The switching of a capacitor stage must cause a changeof current of at least 50mA at current input.- The stage power of the stage to be learned must bebigger than 1% of the measuring range of the control-ler.

Attention!After learning, the saved configurations must be checked,if they are plausible.

Power station serviceBy setting "power sta-tion service" the reac-tion of the controller atsmall currents is con-trolled.Presetting: Power station service = "oFF"

Power station service= "oFF"If no or a very small current is flowing through thecurrent transformer, all connected capacitor stages areswitched off one after the other.

Power station service = "on"If delivery (power station service) and consumption ispossible, connected stages must remain connected tothe net, even if no current is measured.

ProgrammingExample: Power station serviceGo to power station service in expanded programmingusing key 3.

If real power is generated in a certain application, thefollowing situations can arise:Case a.The generated real power is smaller than the demand.Additionally real power is delivered by the energy sup-plier.

Case b.The generated real power is bigger than the demand.Real power is supplied.

Case c.The generated real power corresponds to the demand.

In all cases the required reactive power is supplied bythe energy supplier, or even better, by a compensationsystem.The following situation can come into being. The neededreal power is completely generated (case c.) by the gen-erator, and the reactive power is completely suppliedby a compensation system.There is no current flowing through the current trans-former. If the power station service, by mistake, is on"oFF", the capacitor stages are disconnected. Then areactive current is flowing again through the currenttransformer. The controller detects a need for compen-sation, and connectes the stages again. The reactive cur-rent is compensated. Again, no current is flowing.The problem is, that the number of switchings is in-creased.For power station service, especially in case c, the powerstation service should be set to "on".

Ventilator controlWith the temperaturefeeler, inserted inDynamiC , and a ven-tilator, a simpleventilator control canbe established.Therefore, an

upper temperature limit, alower temperature limit and aswitching output

must be fixed.Please note, that the inner temperature of the DynamiCis about 2°C over the outer temperature.A relay output or the alarm output (option) serves asventilator output.If the switching output 0 is assigned to the ventilatorcontrol, the ventilator control is not active.An upper and lower temperature limit can be set. Thetemperature limits can be set in the range of 0°C and98°C in 1° steps. While programming, you can only setan upper limit, when it is at least 1°C over the lowerlimit.

Attention! If an output is programmed for ventilatorcontrol, and if it is also programmed for a fix stage oralarm output, the ventilator control has higher priority.

Overtemperature disconnectionIn cabinets there mightbe an exceeding of theinner cabinet temper-ature, effected bypower dissipation ofcon-nected capacitor stages or too high outer tempera-ture.In that case, also the DynamiC controller is heated up,and the inner temperature feeler detects this rise of tem-perature with a little delay. With the overtemperaturedisconnection, connected stages can be disconnectedin order to decrease the inner temperature and to protectthe capacitors from damage.The following values can be set:

- upper temperature limit,- lower temperature limit and- pause time.

Table 1: Correction angle, measurement L-N

Connection configurationDynamiC can be de-livered in twoconnection varieties forthe measurement andsupply voltage.In the version measurement L-L, the measurement andsupply voltage must be taken from two outer conduc-tors. In version measurement L-N, the measurementand supply voltage must be taken between outer con-ductor L and neutral N.

Correction angleThe controller DynamiC indicates the power factor,real and reactive power correctly, if current and voltagewere connected according to the type plate andconnection diagram. The phase shift between voltageand current must not be corrected, and the correctionangle is 0°.The correction angle can be selected in the range of 0°- 359° in one degree steps.

If the user cannot connect DynamiC according to theconnection diagram, this can be corrected according tothe correction values of table 1 or 2.Devices for version L-N can be corrected with the cor-rection angles of table 1.Devices for version L-L can be corrected with the cor-rection angles of table 2.

If the connection fault is not known, the correction an-gle can be determined automatically by using the “learn”function.
