Hello Dear Friend,
thank you very much in advance for your quick reply and help. And very happy to read your supportive guidelines. Before getting your message i was browsing and explore between all the pages (here in database of forum) and a 1km long list of the reasons of T error have been read. Forsure will back here with answer because it is an important repetitive error.
Thank you
Andy

 

Hello Dear Adil
I hope it finds you very well gentleman and thank you again for your efforts and supports. I have done what you have said but didn't help. I forgot to say that this press has an isolator step-down transformator ( for the main electric power i mean, located out of main cabinet, by customer) and by chance i checked the output voltage on it and at one single phase the the value was over 30 volts more than it should be. i have swapped this transformator with another correct (same power) and "T" disappeared. it sounds very weird to me, but it seems fault has been fixed (hopefully) and now it is printing...Any way hereby I would like to express my special gratitude for your help and Best Regards, Andy
