Power Factor Correction
Why can be encountered the error "Connection Not Detected" while performing "Connection Correction" in RGA / RGSR Series power factor controllers?

RGA / RGSR power factor controllers have 2 current transformer inputs, “Current1” and “Current2”.

Current transformers mounted on the main switch must be connected to the “Current1” input. For the use of special functions such as "contactor adhesion alarm" to the "Current2" input, current transformers installed under the compensation switch must be connected.

 

If it is connected to the “Current2” input, the RGA / RGSR Series power factor controllers give you a warning as “Connection Not Detected”.

 

The ‘’Connection Correction’’ process can be completed via the connection to the ‘’Current1’’ input without any problem.

Why is energy not coming into the RGA / RGSR and RGP series power factor controllers?

RGA / RGSR and RGP Series power factor controllers have an auxiliary supply input that provides the energy needs of the device as well as the measurement input. The device can be energized by making an auxiliary supply connection.

Why might the inductive load driver give an error in SVC systems?

One of the issues that cause inductive load drivers to fail (LEDs blink continuously) is whether the neutral terminal is not connected or connected to the wrong terminal. However, the fact that shunt reactors are never introduced or misrepresented is also a factor that causes the SVC system to malfunction and the inductive load driver to fail.

The problem can be eliminated by controlling the terminal connections of the inductive load driver and introducing the shunt reactors again.

How can we introduce the shunt reactors that connected to the step in the RG3 Series Power Factor Controllers ?

RG3-CL and RG3-CLS series power factor controllers that support shunt reactor use, automatically recognize capacitor steps during “auto setup”, but you need to manually define shunt reactor steps. You can access our shunt reactor identification process video by clicking the link below.

What kind of a path should be followed in enterprises that encounter capacitive reactive cost or where capacitive reactive rates are high?

It can be said that shunt reactors should be used in enterprises with high capacitive reactive ratios, but it is not a healthy method to predict the shunt reactor value to be added to the system only by looking at the electricity bill.

For a more accurate detection; For 3 days, index values should be taken twice a day from 08:00 in the morning and 6:00 p.m. Then, the shunt reactor capacities to be added to the system can be determined by interpreting these index values.

If there are both inductive and capacitive loads in the enterprises and these loads are variable, the most suitable solution to be applied is the SVC system.

Consisting of RGSR or RGP-SR series power factor controller, inductive load driver, capacitors and shunt reactors, the SVC system ensures that both inductive and capacitive reactive ratios are kept within legal limits.

Is it possible to be placed the ENTES capacitors on the panel horizontally?

Capacitors can be produced as oil-resin type and dry type. Oily type capacitors can leak oil over time depending on the production technology and therefore horizontally mounting is not recommended. Dry type capacitors, do not contain any oils etc., so they do not make an occurrences any leakage risk when placed as horizontally.

 

In the ENTES Product Range, CXD, CMD, CF, CM and C10 series capacitors are dry type capacitors and they are suitable for horizontal mounting.

 

Although C100 series capacitors are oil-resin based (ENT.C100-50 kVAr (triangle type) is a dry type capacitor), it is suitable for horizontal installation thanks to its special technologies.

 

In summary; All capacitor series in ENTES product range can also be used horizontally in panels.

What is the difference between Standard Series and Industrial Series Shunt Reactors?
Industrial series shunt reactors are designed for use in large-scale industrial plants and businesses operating under heavy conditions (the places where the electricity grid is dirty).
 
Standard series shunt reactors are designed as a relatively economical alternative to the industrial series to operate in medium and small enterprises and in conditions where the electricity grid is cleaner.
Why is the Auto Setup problem encountered in power factor controllers? How is it solved?
In case of Auto Setup problem, you can follow the steps below;
 
If the current transformers connected to the power factor controller with different primary current values, Auto Setup problem may be encountered. Firstly, it should be checked that the current transformer primary values are the same.
 
For the correct power factor correction, the location / sequence of the current transformer and power factor correction supply connections to the power factor controllers on the busbar are extremely important. For the power factor controller to work properly, current transformers must always take place before the power factor correction supply. In case of Auto Setup problem, current transformer and power factor correction supply order should be checked.
How to Perform Step Introduction in RG3 Series Power factor controllers?

At the end of the operations that are affecting compensation such as capacitor change, the automatic step identification (Auto Setup) operation must be performed over the power factor controller. The following steps should be followed for this process;

  • Initially, enter the menu by pressing and holding the "setting" button for 3 seconds.

  • - “Auto” appears on the screen. By pressing the "set" button again, the "auto operator???" menu is entered.

  • - Press the up arrow button once to go to the “auto setup”, press the “Set” button and then “off” option is made “on” with the up arrow button.

  • - By pressing the "set" button again, automatic recognition and operation are started.

What kind of problems occurs grounding of current transformers by bridging?

Connections of ENTES hardware must be made according to the descriptions and diagrams in the installation instructions. In equipment with external current transformer, problems such as failure to make accurate measurements and failure of current cards may be encountered as a result of bridging grounding of current transformers.

How to Perform Step Introduction in RG3 Series Power factor controllers?

At the end of the operations that are affecting compensation such as capacitor change, the automatic step identification (Auto Setup) operation must be performed over the power factor controller. The following steps should be followed for this process;

 

-  Initially, enter the menu by pressing and holding the "setting" button for 3 seconds.

- “Auto” appears on the screen. By pressing the "set" button again, the "auto operator???" menu is entered.

- Press the up arrow button once to go to the “auto setup”, press the “Set” button and then “off” option is made “on” with the up arrow button.

- By pressing the "set" button again, automatic recognition and operation are started.

 

 

What should be done if the power factor controller's steps activation problem is encountered in the enterprises with high harmonic level?

The power factor controllers can disable the steps that they are activated to protect the steps due to excessive current loading in the system in the operating systems.

For the permanent solution of this problem; By applying active harmonic filter solution, it is necessary to decrease the harmonic level in the system or you need to apply harmonic filter power factor correction system.

For the temporary solution ; "THDI" value in the "alarm" menu in the power factor controller settings should be set to "0000". By doing this, we turn off the harmonic alarm of the power factor controller.

Is a password required to enter the setting menu of power factor controllers?

The set input password of the power factor controllers of the RG- and RG3 series are “passive” at the factory settings. Users can change this setting to “active” status according to their wishes.

In the new generation power factor controllers such as RGA, RGSR and RGP, the setting input password is “active” in the factory settings. Users can change this setting to “passive” status according to their wishes.

 

What is the password for entering the setting menu of power factor controllers?

For the RG and RG3 series power factor controllers, the factory default password is “1234”. If it is not changed by the user, this password must be entered when entering the setting menu.

In the new generation power factor controllers such as RGA, RGSR and RGP, the factory default password is “0000” and if it is not changed by the user, this password must be entered when entering the setting menu.

 

If the password has been changed and not remembered, what should be done required to enter the setting menu of power factor controllers?

In this case, there is nothing to do by users. Users should be contacted ENTES After Sales Services.

What is the purpose of generator input of the power factor controller?

The connection received from the generator output is made to the generator input located in the power factor controllers. The purpose of this for the power factor controller is to detect that the generator is activated when the power is cut off from the mains and to compensate according to the cosfi value (cosfi2) defined for the generator.

It is recommended not to connect mains supply to the generator input. If connected, the power factor controller will compensate according to the predefined value of 0.85 cosfi. In this case, your reactive rates may go beyond the legal limits and you may encounter reactive penalty.

What is the reason for the RG3 series power factor controller gives “overvoltage warning”?

Our RG3 series power factor controllers have an overvoltage alarm. The factory-set value is set to 260V, and when the voltage exceeds this value, the power factor controllers disable the steps for protection.

Users can change this set value optionally from alarm settings.

Can current transformers be connected to two different device with parallel connection?
If the current transformers are connected to two different device with parallel connection, the current values measured by the device will not reflect the truth and therefore will not function properly.
 
For example; When current transformers are connected to both power factor controller and multimeter by parallel connection, reactive power will not be compensated by the power factor controller as much as it will and therefore reactive rates will be encountered; due to reaching of reactive ratios’ to the out of legal limits.
What is “step limitation” in power factor controllers of RG3 series, how is “automatic step recognition” done when the limitation is made?

RG3 series power factor controllers have a "step limitation" feature. With this feature, for example, a 12-stage power factor controller can be limited to activate only 6 stages.

If this limitation is made, during the automatic stage identification process, the relay will only try to recognize 6 stages.

If it is desired to make a promotion for all levels, the step limitation should be removed from the settings menu.

What could be the reason of encountering “overpower factor correction warning” while installing RG Series single phase power factor controller?

Altough  the current transformer ratios are selected correctly via the power factor controller, if excessive power factor correction warning is encountered, the secondary (k and l) ends of the current transformer may be reversed. Current transformer secondary (k and l) ends should be reconnected and replaced.

Power Quality and Energy
How to make connections in the MPR-4 series, what should be done in case of an incorrect connection?
Which checks should be done if there is an error in the measurement values of the network analyzers?
In ENTES network analyzers, bidirectional active energy measurement can be made as import and export. The "import" refers to the electricity we receive from the electricity grid, and "export" refers to the electricity we supply to the electricity grid.
 
In operations where only energy is consumed, there is expected that kWh values will be seen on the import side and no value on the export side.
 
If the user sees kWh values on the export side in the network analyzer even though there is no electricity generation, it means that the current transformer connections are wrong.
 
For error control in connection of current transformer terminals in EPR-04, EPM-07 and MPR-53 Series network analyzers; Using the Up / Down keys, go to the instantaneous power (W) screen, if the dot sign flashes in the lower right part of the screen where the values in 3 phases are displayed, the current transformer terminals of that phase are reversed, it should be corrected. After correcting, no dots will appear on the same instant power (W) screen. These operations should be done until all points are not visible in 3 phases.
 
For error control in connections of current transformer terminals in MPR-4 Series network analyzers; You can check your connection using the test function. When you press the TEST button for 3 seconds, the device switches to Test Mode. For the Test Mode to work properly, the following test conditions must be officiated:
 
• At least 20% of the rated voltage should be applied to the voltage measurement inputs.
 
• At least 10% of the rated current should be applied to current measurement inputs.
 
• The angle difference between current and voltage inputs must be less than 30 degrees (Cosφ value must be between inductive 0.87 and capacitive 0.87.)
 
• During the connection test, the device checks connections and can fix them internally or leave the physical correction to the user.
 
• If there is an error between the voltage inputs, it can only be corrected by changing the physical connections.
 
After the connection errors at the current transformer ends are corrected, voltage connections should also be checked for potential connection errors.
 
On the EPR-04, EPM-07 and MPR-53 Series network analyzers, 3-phase Cosφ values are checked for error control in the connection of the voltage inputs.
 
In the MPR-4 Series network analyzers, the test function is used to check whether there is any voltage connection error in the device.
 
In EPR-04, EPM-07 and MPR-53 Series network analyzers, if the connections are done correctly, measurements and records will be straight.
 
In MPR-4 Series network analyzers, after all, connections are done correctly, we use the test function for control. When we see the phrase "TEST SUCCEED", all wiring of the device is correct.
 
 
 
 
 
 
 
Can direct connection to ENTES network analyzers without using a current transformer?

ENTES network analyzers are designed to measure all electrical parameters in the electrical network.

Direct connection up to 5 Amps can be made on EPR-04, EPM-07, MPR-53, MPR-4X series network analyzers. The current transformer must be connected to the device for currents of 5 Amperes and above.

MPR-1X, MPR-2X and MPR-3X series network analyzers cannot be connected directly, in this condition current transformer connection must be made to the devices.

What causes MPR-4 Series Network Analyzer to display voltages incorrectly?

In case the voltage values are shown incorrectly, there are 2 issues to be checked firstly;

  • • If the voltage transformer is not used, the voltage transformer must be marked as “passive” in the settings.

  • • It must be ensured that the voltage and neutral terminals are connected to the correct terminals. The most common mistake is to connect the neutral terminal to the 4th voltage input, in this conditions the neutral connection must be made to the neutral terminal (16).

Why do MPR-5 series energy analyzers have 2 energy meters and using for what purpose?

The network analyzers with LED displays contain two factory-made energy meters. Thanks to the digital input feature in these 2 separate meter devices, it is used to distinguish between grid and generator consumption.

1.Energy Counter

1-I: Import active energy (kWh) 1-E: Export active energy (kWh)

1-L: Inductive reactive energy (kVArh)

1-C: Capacitive reactive energy (kVArh)

2. Energy Meter

2-I: Import active energy (kWh)

2-E: Export active energy (kWh)

2-L: Inductive reactive energy (kVArh)

2-C: Capacitive reactive energy (kVArh) Import active energy shows the energy consumed from the grid or generator.

Export active energy indicates this amount of energy if the grid is fed from the facilities where electricity is produced.

Inductive and capacitive reactive energies are the parts in which the reactive energies consumed are shown separately.

The working principle of these counters is as follows;

These energy meters in the device are "ON" at the factory and count in two meters under any condition.

(Can be controlled from the Eng Cnt menu).

What could be the reason why the voltage values are higher than normal in the EPM-04 Multimeter?

If a voltage transformer is not used but its value is defined in the hardware settings, the voltage value displayed on the multimeter will not reflect the reality.

In case the voltage transformer is not used, the voltage transformer value should be selected as “1” from the settings menu.

What could be the reason why the ammeter shows incorrect current values?

The most important reason why the ammeter shows the current values drawn incorrectly is that the current transformer ratio has been entered incorrectly.

In this case, what needs to be done; firstly, it is to check the primary current value of the current transformer used. For example; If the current transformer used is a model of 100/5, the primary current value is 100A. In the next step, it is necessary to make sure that the primary current value is entered as 100 in the setting menu of the ammeter.

What could be the reason for no measurement value shown on the display of the EVM Series Voltmeter?

EVM series multimeters have 2 voltage inputs. One of them (Vin) used for the terminal voltage measurement, the other one (Un) terminal is used for the supply of the device.

If there is no voltage connection to the Un terminal, the measurement values cannot be displayed on the screen since the device has no energy supply. So highly recommended to check this connection.

What could be the reason why EPR series energy and power meters could not be pulse?

If pulse output cannot be obtained from EPR series energy and meters, connections may be wrong. Current and voltage connections should be checked and incorrect connections should be corrected.

If there is no current transformer primary value input menu in EPR-04S model power and energy meter settings, what could be the reason why?

EPR series energy and power meters have 2 different versions as, X / 5 current transformer compatible models and CT-25 current transformer compatible models. If there is no current transformer primary value input menu in your hardware, your device is suitable for use with CT-25 current transformer. You can purchase CT-25 current transformer or purchase hardware compatible with X / 5 current transformer.

Protection & Control
I cannot get contact output from DTR Series Astronomical Time Relay. What could be the reason for this?

DTR series contain internal batteries. Due to this battery the current date, time and programs are not affected by power interruption, but the device must be powered to get contact output.

If the device is not energized (no supply connections or problems with the connection) or if there is a power interruption, the contact output will not be given.

Why The DTR Series Astronomical Time Relays Do Not Work According To The Program Set?

If DTR series astronomical time relays to operate in accordance with the set time intervals, some settings must be made over the device.

If you select the city that you are in and set the “Time Zone” setting to 03:00 if it’s 02:00, the DTR series astronomical time relays will work between exact time you set, including sunrise and sunset times.

You can watch our video below to change the Time Zone (Summer / Winter Time Setting);

What to do if we can not remember of the setting menu login password of the DTR Series Astronomic Timer Relay ?

Users can optionally set a password on ENTES hardware so that no settings can be changed except by authorized persons.

If this password can not be remembered, ENTES customer service should be contacted.

Why do we encounter “Holiday Mode” on DTR Astronomical Time Relay Screen? What should we do?

DTR astronomical time relays have 1 battery to keep all information in memory. This battery has a certain lifespan and needs to be replaced when this period is over.

If the battery is not replaced and the device supply is cut off, the relay software may be damaged and the “holiday mode” warning may result in an obstacle to the use of the hardware.

In DTR models with replaceable battery feature, the battery can be changed by opening the cover under the device. For models that do not have this feature, our customer service department should be contacted and can sent your device to our technical service department for repair.

Can GKRC-02F Voltage Protection Relay be used as Single Phase?

GKRC-02F is a three phase protection voltage relay. It is not suitable for use as a single phase, as it also has a phase sequence protection feature. For single-phase use, GKRC-M2 or MCC-1D models can be preferred.

Can GKRC-02 Voltage Protection Relay be used as Single Phase?

GKRC-02 is a three-phase voltage protection relay. It is possible to use the relay as single phase, for this connection must be made by bridging the single phase applied to the voltage inputs to other phases.

What can be the reason for not getting contact output from the MKC-03 engine protection relay although voltages are normal?

Phase sequence protection is available on the MKC-03 motor protection relay. If the phase sequence is entered incorrectly, no output will be obtained from the contact. It must be checked that the phase order has been entered correctly.

Which function of the time relay we should use to make its contact switch on / off periodically for 24 hours?

In order to perform this operation, the time relay should have a flasher function. MCB-9 or MCB-25 time relays have this function.

Service and Communication
Enermedic - Why is there a gap in the consumption summary graph?

As of v3.0.0, Enermedic collects data from the devices periodically through the instant monitoring method. If the data cannot be read from time to time due to physical problems, communication quality and other reasons, gaps may occur in the graphics. To improve the quality of instant reading:

Make sure that the modems and devices are always on. The Energy Doctor cannot read the data during this time, as the hardware will shut down during physical power cuts.

Check that the communication quality of the modems is high on the My Hardware page. Check that the connection quality of the devices with the modems are high via the My Hardware page.

What should be done if faced this error "Mac address defined in Entbus and the server's Mac address is not the same" in the VTS Logfile of Entbus software?

It should be ensured that the MAC address of the VTS server identified through the Entbus user interface is correct.

 

Why are the update delays of live data occurred in the Entbus software?
Submitting the “time-out” parameter value of the EMG device sending the parameters measured by the hardware to the Entbus software may cause the data to be updated late. The “Default” value of this parameter is 120 and it will be sufficient to increase it to 240 levels.
What could be the Modbus settings to communicate with GEM or EMG?

If Modbus settings are not done correctly, there will be no healthy communication.

RS-485 menus are available in the menus of our Modbus communication products.

There are 3 more sub-menus on this menu.

• Address

• Baud Rate

• Parity

The address represents the identity of each device and can take a value between 1 and 247. For each device to be connected to an EMG, this number must be unique, and if there are two devices with the same ID, communication cannot be provided.

Baud Rate defines how quickly data is transferred in a communication link. For each device to be connected to an EMG, the Baud Rate value must be the same, if there are devices with different Baud Rate values, communication cannot be provided.

Parity is used to see if the data received in serial signal communications are sent correctly. There are 3 types as None, ODD and EVEN. Parity must be selected as NONE for each device to be connected to an EMG. If there are devices with different Parity expressions, communication cannot be provided

These 3 settings mentioned above must be made correctly between the products to be communicated and the same settings must be made for a healthy communication infrastructure via communication converters such as EMG & GEM.

Why could encounter the problem of not communicating despite the hardware connection to the EMG-02 Ethernet modem?

The EMG-02 ethernet modem enables communication of up to two hardware because of design.

Modbus IDs of this hardware must be 1 and 2. IDs given to devices other than these numbers will cause failure to establish a communication connection with EMG-02.

What to do if alarm and report emails are not reached to users in Entbus Pro software?

Mail testing can be done from the Options → My Information field in the software menus.

Or a technically different test can be done with the following steps. Necessary controls are provided according to the result.

• The terminal interface opens. (Cmd) • Commands are applied in a case-sensitive manner, in sequence:

• telnet [mailserver address] [mail out port] • HELO [mailserver address]

• MAIL FROM: [mail address of the person who will send the mail]

• RCPT TO: [mail address of the person to whom the mail will go] (write your email address)

• DATA • SUBJECT: [subject title]

• [mail content]

If mail can be sent with this method, the problem is not caused by the Entbus software, it should be checked that there is a problem caused by the mail server.

What could be the reason for the error in the EMG-02 installation?

If the operating system of the computer which EMG-02 driver is installed is Windows 8 or Windows 10, the signature authorization must be revoked before installation

After the signing authority has been canceled, the driver identification process can be performed.

What should be done if the Autoupdate.exe, which provides automatic updating of ENTES software, is deleted by some antivirus programs where security levels are at the highest level?

In the face of such a situation, in order to repair Autoupdate.exe file, only this feature can be re-installed by using installation CD.

In order not to encounter the same problem again, it should be ensured that the update folder is not scanned in the settings of your Antivirus program.

What should be done if software fails to delete hardware and connection port?

In the event of such a problem, we request that you send us the screen image and your company information via the teknikdestek@ENTES.com.tr mail address so that we can understand why.

We can plan remotely or on-site technical support services for you after our investigations

What should be done if a warning is received in the VTs Log file saying "connecting problem to the distributor"?

There may be a connection problem between VTS and Distributor.

Check the "DistributorIP" field and related ports in the appconfig file of the VTs. If you are using any virus programs or firewall software, make sure that you have defined the appropriate rules.

Check the SQL Server service is running and the storage capacity is sufficient.

What should be done if the EMG series ethernet converter is not introduced to the computer?

Windows signature authorization should be checked. With this correction, the identification and configuration settings of the EMG series can be made

In the Enermedic, we only connect energy efficiency hardware to the loads without defining energy efficiency hardware to the main board, and after a while the energy efficiency hardware with the lowest NAD address on the loads is automatically connected to the main board. Why is this caused?

In accordance with the Enermedic's working principle, in case no hardware is connected to the main panel, the energy efficiency hardware with the lowest NAD address is automatically connected to the main panel. Loads of the Enermedic cannot be displayed properly without connecting hardware to the main board.

However, the user can manually define an imaginary hardware to the Enermedic and connect it to the main panel if he wishes. Although the Enermedic does not communicate with this imaginary hardware, the automatic hardware discovery behavior will be terminated as it will continue to be used as the main board hardware.
