Ask a question

This session gathers all common questions from who is contacting Thyeast. It is daily updated, so read it before making an inquiry to the technical stuff.
If you would like to receive a response to a particular question, herewith not listed, please go to the Contacts page and select the appropriate department to contact. However, we read them and use your suggestions to improve our site.

1. I need to prepare a setting file "Off line", from zero. Can I do it or have I to be connected?

   Yes, you can do it. But you have to start using the correct template file. If you are not sure about it, just connect once to the relay. It will automatically open the correct template, save it on your PC and work on that.

   
   

2. I've a setting file on my PC. How can I send to the relay?

   First of all the file must be compatible (see the previous FAQ) otherwise the internal DB can be corrupted. In case you are sure it is the right file just follow the command in ThySetter: Procedures -> Send Data.

   
   

3. How can I download on my PC the setting of a ProN?

   The correct way to get data stored in the memory of the relay is the command in ThySetter:

   Procedues -> Receive Data.

   Do not use the File -> Save (or Save As). It is only for local purposes.

   
   

4. Are the output contacts polarized?

   No, the output contacts are free voltage contacts type. All the output relays are freely programmable as latched/No latched, Energized/De-energized. Are not timers type.

    

   
   

5. Can I carry out a protective relay network?

   Yes, using ProN relay is very easy. Just assign an address to every single relay and follow all common instruction in case of a PC’s network.

    

   
   

6. Can I use any output relay for logic selectivity?

   Yes, but you have to program it in a proper way. We highly recommend to adopt the dedicated output in order to perform a logic selectivity scheme for two main reasons: continuous check and possibility to use fiber optic, useful in case installing in high disturbance environments.

   
   

7. Have you a supervisory and control software for managing a relay network?

   Yes, you can monitor a ProN relay network with our software. Ask to the technical support further information.

   
   

8. How can I program a ModBus communication?

   Use our programming manual downloadable from Product pages. Every manual is related to the firmware version.

   Pay attention to download the one suitable for your product.

   
   

9. How can I program a ProN relay as a PLC?

   Sending your compiled instruction language code to the relay. The PLC compiler is working under license.

   
   

10. How can I recognize the firmware version?

    Go in READ -> INFO menu. Read parameter called Application sw release.

    
    

11. I have to carry out a High impedance restricted earth fault protection, 87NHIZ. May I use NA10?

    Surely. Furthermore you can use every other earth current relays (50N/51N) as well. Whenever you need more info regarding to 87NHIZ visit our Application Note session.

    
    

12. If I have more than one PC how many PLC or Oscillographic licenses do I need?

    The license is available either as a file or as a USB key. It is possible to share the USB key on every PC.

    
    

13. If I have more than one relay how many PLC or Oscillographic licenses do I need?

    Just one, both in case of PLC and Oscillography.

    
    

14. Is the Oscillographic function free?

    Yes, every relay can work as oscillographic recorder. When you have to download the record you need the ThyOSC license.

     

    
    

15. Is ThySetter a free software?

    The ThySetter base version is for free, without any license for additional features like oscillography and PLC.
    The ThySetter OSC license is necessary to retrieve oscillographic records and ThySetter PLC is necessary to compile an Instruction Language code.
    Once you have an oscillographic record you can open it using every third part Comtrade file viewer, is not necessary our license.
    Once you have compiled an Instruction Language code you can download it to every relay without our license.

    
    

16. Why cannot I connect to the relay?

    Download and install the last ThySetter version. Leave Automatic connection type and select the relay series properly. If you are using a RS232/USB converter check whether it is working correctly.
