Product description
Intended use
The reactive power controller Prophi together with ex­ternal capacitor stages, serves for step by step control­ling of the phase shift angle cos(phi) in 50/60Hz low voltage networks. Depending on the type of the reac­tive power controllers Prophi, contactors or semi con­ductor switches can be controlled directly. Additionally, the following electrical quantities are meas­ured 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 voltage or rated current.
The connection is carried out on the back side via touch proof spring power terminals. Measurement and supply voltage are taken from the measurement voltage and must be connected to the building installation via a separation (switch or power switch) 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, the transistor outputs are provided for the control of fast switching thyristor modules, switching at zero crossing.
Hints for maintenance
Before delivery the device is tested in various safety checks and marked with a seal. If the device is opened, these checks must be repeated. There is no guarantee for devices, which are opened out of the manufacturing works.
Repairing and calibration
Repairing and calibration work can be carried out in the manufacturing works only.
Front foil
The cleaning of the front foil must be done with a soft cloth using a common cleansing agent. Acid or acidic agents may not be used for cleaning.
Waste management
The device can be disposed as electronical waste ac­cording to the legal regulations and recycled.
Data protection
The data protection is carried out in a none volatile memory (EEPROM). Changed programming data are saved immediately.

Switching of capacitor stages
Prophi calculates the required reactive power to reach the set target-cos(phi) from the current from one outer conductor and the voltage between two outer conduc­tors. If the cos(phi) deviates from target cos(phi), exter­nal capacitor stages or transistor outputs are switched on or off. In automatic mode the capacitor stages are switched in or off, when the required reactive power is higher or equal to the smallest stage power. If the power of the first capacitor stage is three times as high as the measured real power, all capacitor stages are switched off.
Switching outputs
Depending on the variety of Prophi, relay or transistor outputs serve as switching outputs. The relay outputs are suitable for controlling contactors and the transistor outputs can switch thyristor modules, that switch in zero crossing of voltage. For relay outputs the time between two connections or disconnections is set to two seconds. Transistor outputs have no limitation of the switching period.
Net return
After net return, the set discharge time runs for the relay outputs. The transistor outputs do not mention the discharge time.
Funktional description
Measurement
The measurement is suited for 3 phase systems with or without neutral conductor for frequencies of 50Hz or 60Hz. The electronical measurement system records and digitalizes the effective values of voltage between L2 and L3 (L-N Option) and the current in L1. In each second several snap check measurements are carried out. As the current is only measured in one outer conductor, and the voltage only between two outer conductors, the measured values, which are related to all three outer conductors, are exact for equal loaded outer conductors only. The following electrical quantities are calculated:
Current and current harmonics Voltage and voltage harmonics Real power, sum Apparent power,sum Reactive power, sum Reactive power for each stage Reactive current for each stage Cos(phi), Net frequency.
The following information can be indicated:
Number of switchings of each stage, total connection time of each stage and
the inner temperature. Prophi measures the frequency of the measurement and supply voltage and shows the average over 10 seconds.

Hints for installation
Mounting place
The reactive power controller Prophi is suited for mount­ing and operation in reactive power compensation sys­tems.
The connection is carried out on the back side via touch proof spring power terminals.
Measurement and supply voltage
The measurement is suited for 3 phase systems with or without neutral conductor. Measurement and supply voltage are taken from the measurement voltage and must be connected to the building installation via a separation (switch or power switch) and an overcurrent protection (2A...10A).
The reactive power controller measures and supervises the voltage between two outer conductors. If one of those two fails, the reactive power controller gets no more measurement and operating voltage, and switches on the capacitive stages after net return according to the programmed times. If the third outer conductor is missing, this will not be recognized by the reactive power controller. If the con­tactors are supplied by this outer conductor, the contac­tors can attract simultaneously and without considera­tion of the discharge time after net return.

Current measurement
The current measurement is carried out via ../5A or ../ 1A current transformers. If the current must be measured with an Amperemeter additionally to Prophi, it must be connected in series.
Sum current measurement
If Prophi is connected to a sum current transformer, the total transformation ratio must be programmed.
Attention!
For unequal load of the outer conductors, the current should be measured in the outer con­ductor, which is loaded most heavily.

Measurement and supply voltage
The controller Prophi can be delivered in two connec­tion varieties for the measurement and supply voltage. In the version measurement L-L, the measurement and supply voltage must be taken from two outer conduc­tors. In version measurement L-N, the measurement and supply voltage must be taken between outer con­ductor L and neutral N.
Before connection, please ensure, that the local net con­ditions match the data on type plate. The range of the measurement and supply voltage is given by the type plate and is connected via a fuse (2…10A, time lag type)

If the measurement and supply voltage is within the allowed range, Prophi indicates the voltage on the ter­minal. While measuring via voltage transformers, the voltage transformer ratio must be programmed.
Attention!
The measurement and supply voltage must come from the low voltage net, which is su­pervised.
The connected measurement and supply voltage may not exceed the voltage, mentioned on type plate for more than 10% or underscore for more than 15%. To ensure, that the connected measurement and supply voltage is within the allowed range, please check the voltage at the terminal with a voltmeter.
Attention!
Voltage, which is out of the indicated range on type plate can destroy the instrument.
c
Attention!
The operating voltage for the contactors should be received from an outer conductor connected to the controller.

Current measurement
The current transformer is connected to the clamps k and l (/5A or /1A) from the outer conductor L1. Please ensure during the installation of the current trans­former, that the current transformer is passed by the consumer current but not by the compensation current. The current can be measured by an Amperemeter to compare it with the current indicated by Prophi to check. Please note, that the factory's presettings of the current transformer ratio is set to 10 and must be adapted to the existing current transformer. If you should short-circuit the current transformer, the indicated value on Prophi must decrease to 0A.
Examples for the setting of the current transformer Example 1 Current transformer 200A/5A Set Prophi to 40
Example 2 Current transformer 500A/1A Set Prophi to 500
Example 3 Sum current transformer 1000A+1000A/1A Set Prophi to 2000
Attention!
For unequal load of the outer conductors, the current should be measured in the outer con­ductor, which is loaded most heavily.
Real power
If current and voltage are connected to Prophi accord­ing to the connection diagram, a positive real power is displayed in case of real power consumption. Real power with a negative sign in the indication points to the sup­ply of real power or an error of connection. Possible error:
- Voltage and current are measured in the wrong outer conductor.
- The current transformer clamps (k-l) are exchanged.

Switching outputs
The reactive power controller Prophi can be equipped with up to 12 switching outputs. The switching outputs can be equipped either with relay or transistor outputs. If a device is equipped with relay or transistor outputs it is not shown on display. The equipment can be seen in the connection diagram on the back of Prophi.
Relay outputs Capacitor contactors can be connected to the relay out­puts according to the connection example "Relay out­puts".
Transistor outputs
Semi conductor switches, switching at zero crossing, must be connected to the transistor outputs of the reac­tive power controller. The transistor outputs switch the voltage of an external d.c. net supply to the semiconductor switches.
Check switching outputs Please switch in the capacitor stages in manual mode: The inductive reactive power is decreased by the power of the respective capacitor stage. Please switch off the capacitor stages in manual mode: The inductive reactive power is increased by the power of 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 outer conductor.
- The voltage is measured in the wrong outer conductors.
- The current transformer clamps k-l are exchanged.
The reactive power does not change
- The current transformer is installed at the wrong place.
- Switching outputs faulty.
- The wrong control voltage is connected to the switching outputs.

Target-cos(phi) changeover
Via the input target-cos(phi) changeover it can be changed over between target-cos(phi1) and target- cos(phi2). If there is no voltage at the input, the target-cos(phi1) is active. If there is a 85 bis 265V AC connected to the input, the target-cos(phi2) is active.
In the standard display (please see example), apart from the active channels and the actual cos(phi) also the ac­tive target-cos(phi) is indicated.

Alarm output
The alarm relay attracts in undisturbed operation, and the contact of the alarm output is closed. If a distur­bance occurs, the alarm relay releases and the contact is opened. Various events can be assigned to the alarm output via OR-logic interconnections. Each event is as­signed to an alarm number, an alarm delay and alarm duration.
Check alarm output
If there is no alarm, the alarm relay attracts immedi­ately. In order to trigger off an alarm, the threshold for overtemperature can be set to zero, for instance, and the alarm relay releases immediately.

RS485 Interface (Option)
Transmission protocols
Two tran smiss ion pr otoco ls are availa ble fo r the c onnec ­tion to an existing field bus system:
0 - Modbus RTU (Slave) and
1 - Profibus DP V0 (Slave) .
Wi th Mod bus pro tocol you can have ac cess t o the da ta of table 1, and with Profibus protocol you can have access to the data of table 2.
Bus structure
All devices are connected in bus structure (line). In one segment up to 32 participiants can be assembled. At the end and the beginning of each segment, the cable must be terminated by resistors. In
Prophi
you can activate these resistors with two plug-ins. For more than 32 participiants you must use a repeater (line amplifier) to connect the single segments.
Shielding
For connections via RS485 interface, you need a pro­tected and twisted cable. To achieve a sufficient protec­tion result, the shielding must be connected at both ends extensively to the housing or parts of the cabinet.
Cable specifications The maximum cable length depends on cable type and transmission speed. We recommend cable type A.
Cable parameter Type A Typ B
Impedance 135-165Ohm 100-130Ohm
(f = 3-20MHz) (f > 100kHz) Capacity < 30pF/m < 60pF/m Resistance < 110 Ohm/km ­Diameter >= 0,34mm2 >= 0,22mm2

Display and use
In the front side of Prophi there is a digital indication and three keys, with which you can question data and program the device. If you are in automatical mode, you can change be­tween the operating modes using key 1:
automatic mode, manual mode, standard programming and expanded programming
automatic mode manual mode standard programming expanded programming
In standard programming often needed settings are car­ried out such as current transformer ratio or the number of stages. In expanded programming those settings are carried out, which are used not as often, such as discharge time or choke degree.
To reach the expanded programming from automatic mode, leaf through the standard programming using key 1 until the symbol "Prog" appears. Confirm selection with key 2, and you are in expanded programming.
Automatic mode
Automatic mode is marked by the symbol . In automatic mode, there is:
- the switching condition of capacitive stages,
- the actual value of cos(phi) indicated,
- Connection and disconnection of capacitive stages,
- all 15 minutes saving of peak and lowest values, number of switchings of the capacitor stages and the switching times of capacitor stages.
- Indication of measured values using key 2 and 3.
There are three possibilities to reach automatic mode:
- after net return,
- pressing key 1 for about 2 seconds,
- pressing no key in programming mode for 1 minute.

Target cos(phi)
In automatic mode Prophi tries to reach the set target power factor by switching in or off the capacitor stages. It is possible to set a target-cos(phi1) and a target­cos(phi2). Devices without target-cos(phi) changeover always use the target-cos(phi1). Devices with an input for target-cos(phi) changeover switch to target-cos(phi2), whenever the input is active. Range 0.80cap. - 1.00 - 0.80ind.

Current transformer ratio
At the measuring in­put of the current measure-ment either / 5A or /1A current transformers can be connected. In order to get a correct current and power indication, the current transformer ratio of the connected current transformer must be set to Prophi. If the current is measured via a sum current transformer, the total current transformer ratio must be set.
Example 1: Current transformer 500A/5A The current transformer ratio is now calculated to
500A : 5A = 100
A ratio of 100 must be set on the device.
Example 2: Current transformer 200A/1A The current transformer ratio is calculated to
200A : 1A = 200
A ratio of 200 must be set on the device.
Example 3: Sum current transformer Transformer 1 200/5A Transformer 2 400/5A Sum current transformer 5+5/5A The current transformer ratio is calculated to
(200A + 400A) : 5A 600A : 5A = 120

Learning of the configuration
After installation of the controller there is the possibility to learn and save the configuration with the function "learn".
Important requirements are:
- The discharge time for capacitors is set to 60 seconds, when the device is delivered. For capacitors with longer discharge times, the discharge time must be checked and changed before using the "learn" function.
- The current transformer must be flown through by consumer and compensation current.
- The measurement and supply voltage may not be taken from phase to N.
- The compensation system must be ready for opera­tion.
The learning function of the controller is devided into two steps:
Step 1 - Learning of the connection configuration
Here the correction angle between current transformer and measurement and supply voltage is detected.
Step 2 - Learning of the capacitor stages
Here the number of outputs and the stage power of each stage is detected. The following requirements are neccessary:
- The switching of a capacitor stage must cause a change of current of at least 50mA at current input.
- The stage power of the stage to be learned must be bigger than 1% of the measuring range of the control­ler.
Attention!
After learning, the saved configurations must be checked, if they are plausible.
The following actions can be carried out: oFF - No learning. 1 - Step 1, learning of the connection configuration. 2 - Step 2, learning of capacitor stages. 3 - Step 1 + 2, learning of the connection
configuration and capacitor stages.

3. Start learning with
key 1. The symbol learn flashes. The controller learns. During the learning the capacitor stages are switched for several times. The learning can only be interrupted by switching off the power factor controller. The duration of the learning procedure depends on the net conditions, the number of capacitor stages and the set discharge time for the capacitors.
When the learning procedure is finished, the detected correction angle, in the example 270°, is indicated. The learned characteristics are saved.
After 60 seconds the controller changes to automatic mode. Pressing key 1 for 2 seconds, you reach auto­matic mode at once.

Stage ratio
The stage ratio states the ratio of the stage power of the various capacitor stages. The power of the first ca­pacitor stage serves as a reference. The stage ratio is programmable for each stage up to the fifth stage.
Setting range : 0 - 9 In the display only the stage ratio for the capacitor stages 2, 3, 4 and 5 are indicated. The stage ratio for the first capacitor stage is always 1.
Example 2
The stage ratio is programmed to 1:2:0:2:2:2.... In the

Example 1 The stage ratio is programmed to 1:2:4:8:8:8..., and in the four digit-display, only the part "2:4:8:8" is indi­cated.
Stage power
The stage power is the power of a capacitor stage. In the standard programming the stage power can only be pro­grammed for the first stage. In the expanded program­ming you can set the stage power for each capacitor stage. If you only enter the stage power for the first capacitor stage, the other stages are fixed by the stage ratio. The stage power of each capacitor stage can be calculated from the first stage and the corresponding stage ratio.

3. Relay and transistor outputs mixed
In the menus of the standard programming, only the variations 1 and 2 can be programmed. In mixed operation the switching outputs with smaller numbers are always the relay outputs. The relay outputs in mixed operation are programmed in the menu of standard programming, and the transis­tor outputs are programmed in the menu of expanded programming. The programming of the transistor out­puts is carried out indirectly via the stage power of the switching outputs. For transistor outputs, to which no semiconductor switch is connected, a capacitor power of 0kvar is set.

Never­theless they are considered in the stage ratio, so that in the stage ratio in the most disadvantageous case (three fix stages) in the standard programming only two stage ratios are available.

Power station service
By setting "power sta­tion service" the reac­tion of the controller at small currents is con­trolled. Presetting: Power station service = "oFF"
Power station service= "oFF" If no or a very small current is flowing through the current transformer, all connected capacitor stages are switched off one after the other.
Power station service = "on" If delivery (power station service) and consumption is possible, connected stages must remain connected to the net, even if no current is measured.
Programming Example: Power station service Go to power station service in expanded programming using key 3.
If real power is generated in a certain application, the following situations can arise: Case a. The generated real power is smaller than the demand. Additionally real power is delivered by the energy sup­plier.
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 by the energy supplier, or even better, by a compensation system. The following situation can come into being. The needed real power is completely generated (case c.) by the gen­erator, and the reactive power is completely supplied by a compensation system. There is no current flowing through the current trans­former. If the power station service, by mistake, is on "oFF", the capacitor stages are disconnected. Then a reactive current is flowing again through the current transformer. The controller detects a need for compen­sation, and connectes the stages again. The reactive cur­rent is compensated. Again, no current is flowing. The problem is, that the number of switchings is in­creased. For power station service, especially in case c, the power
station service should be set to "on".

Choke degree
The choke degree must be set for choked or combined choked com­pensation systems. The choke degree is needed for the exact determination of the capacitor current. With the choke degree you lay down the switching or­der in combined choked compensation systems. Capaci­tor stages with a high choke degree and low choke degree are switched alternatingly. Capacitor stages with a high choke degree are switched in first. If more but two different choke degrees are set, the capacitor stages with the middle choke degrees are switched as unchoked capacitor stages.
Attention!
To reduce the programming expenditure, the program­ming of the first capacitor stage is taken over for all the following capacitor stages. Nevertheless, the choke de­gree can be changed for the following capacitor stages afterwards.
The choke degree is given for each capacitor stage in percent.
Setting range : 0 - 15%
Stage power
The stage power is the capacitive reactive power of a capacitor stage. The stage power can be set in the ex­panded programming for each stage. In the standard programming, the stage ratio 0:0:0:0 is indicated.

In order to avoid too much switchings of capacitor stages, the capacitor stages are only switched on, when the harmonic threshold of a lower threshold row is ex­ceeded.
If the threshold row is selected for 0, no capacitor stages are switched off. The thresholds of threshold

Possible switching frequencies are:
0,1Hz, (preset)
0,2Hz,
0,5Hz,
1,0Hz,
10,0Hz and
50,0Hz. The delay time between two switchings of transistor outputs is fixed to a minimum of 70ms, except for "50.0Hz".
Switching frequency 0,1Hz If a switching frequency of 0,1Hz is set, a transistor output is switched in and off within 10 seconds one time at maximum.
Switching frequency 10Hz If a switching frequency of 10Hz is set, a transistor output is switched in and off 10 times per second at maximum.
Switching frequency 50,0Hz The time from a change in signal frequency till a switching of a transistor output takes a maximum of 20 ms. The time between two switching’s takes a maximum of 50 ms. If a switching frequency of 50 Hz is adjusted then the serial interface is out of operation

Lower voltage (1)
A lower voltage is recognized, when the measurement and supply voltage is smaller or equal to the rated volt­age given on type plate. If lower voltage occurs, it is recognized after 100ms latest, and the alarm output is active for at least 1 minute. The threshold for lower voltage is programmable in 1% steps in the range of 85% and 99%.
Example Selected threshold : 85% 85% of the rated voltage of 400V make 340V. If the voltage of 340V is underscored, the alarm relay releases.
Attention!
If the measurement and operating voltage falls below 85% of the rated voltage, all capacitor stages are switched off after about 20ms.
Overvoltage (2)
Overvoltage is recognized, when the measurement and supply voltage is higher or equal to the rated voltage given on type plate. If overvoltage occurs, this will be recognized after 100ms latest. The alarm output will drop out for at least 1 minute and connected capacitor stages will be disconnected in steps of 10 seconds.
The threshold for overvoltage can be programmed in the range of 96% up to 110% of the rated voltage in 1% steps.
Example Selected threshold : 110% 110% of the rated voltage of 400V make 440V. If the voltage of 440V is exceeded, the alarm relay releases.
Underscoring of the measurement current (3)
The rated current of a measuring input is 5A. If the selected threshold for the measurement current is un­derscored, after 100ms maximum the alarm relay re­leases for at least 1 minute. The threshold for underscoring the measuring current can be programmed in the range of 0% up to 28% of the rated current in 2% steps.
Example Selected threshold : 10% 10% of the rated current of 5A make 0.5A. If the current of 0.5A is underscored and the alarm relay releases.
Exceeding of measuring current (4)
The current of current measurement input is 5A. The rated current of the current measuring input is 5A. If the preset threshold for the measurement current is ex­ceeded, the alarm relay releases after 100ms latest for at least 1 minute. The threshold for exceeding the measurement current can be set in the range of 50% up to 120% of the rated current in 5% steps.
Example 1 Selected threshold : 95% 95% of the rated current 5A make 4.75A. If the current of 4.75A is exceeded, the alarm relay releases.
Insufficient capacitor output (5)
If the required compensation power is not reached for one hour, the alarm relay releases for at least one minute.
Supply of real power (6)
If more real power is supplied than consumed (power station service), the alarm relay releases after 100ms latest for at least 1 minute.
Harmonic thresholds (7)
If a value in the selected harmonic threshold table is exceeded, the alarm relay releases after 100ms latest for at least 1 minute.
Overtemperature (8)
The reactive power controller is laid out for the operat­ing temperature range between -10°C and +55°C. The inner temperature of the reactive power controller is about 2°C higher than the temperature within the cabi­net. If the programmable threshold for the controller inner temperature is exceeded, the alarm relay releases after 100ms latest for at least 1 minute. Setting range for the temperature : 0..99°C
Attention!
For inner temperatures of more than 70°C the alarm will always be raised.

Ventilator control
With the temperature feeler, inserted in Prophi, and a ventila­tor, a simple ventilator control can be estab­lished. Therefore, an
upper temperature limit, a lower temperature limit and a
switching output must be fixed. Please note, that the inner temperature of the Prophi is about 2°C over the outer temperature. A relay output or the alarm output (option) serves as ventilator output. If the switching output 0 is assigned to the ventilator control, the ventilator control is not active. An upper and lower temperature limit can be set. The temperature limits can be set in the range of 0°C and 98°C in 1° steps. While programming, you can only set an upper limit, when it is at least 1°C over the lower limit.
Attention! If an output is programmed for ventilator control, and if it is also programmed for a fix stage or alarm output, the ventilator control has higher priority.

Overtemperature disconnection
In cabinets there might be an exceeding of the inner cabinet temper­ature, effected by power dissipation of con-nected capacitor stages or too high outer tempera­ture. In that case, also the Prophi controller is heated up, and the inner temperature feeler detects this rise of tem­perature with a little delay. With the overtemperature disconnection, connected stages can be disconnected in order to decrease the inner temperature and to protect the capacitors from damage. The following values can be set:
- upper temperature limit,
- lower temperature limit and
- pause time.

Connection configuration
Prophi can be delivered in two connection va­rieties for the measure­ment and supply volt­age. In the version measurement L-L, the measurement and supply voltage must be taken from two outer conduc­tors. In version measurement L-N, the measurement and supply voltage must be taken between outer con­ductor L and neutral N.
Correction angle
The controller Prophi indicates the power factor, real and reactive power correctly, if current and voltage were connected according to the type plate and connection diagram. The phase shift between voltage and current must not be corrected, and the correction angle is 0°. The correction angle can be selected in the range of 0°
- 359° in one degree steps.
If the user cannot connect Prophi according to the connection diagram, this can be corrected according to the correction values of table 1 or 2. Devices for version L-N can be corrected with the cor­rection angles of table 1. Devices for version L-L can be corrected with the cor­rection angles of table 2.
If the connection fault is not known, the correction an­gle can be determined automatically by using the “learn” function.
