TRAUB TND 300 two subsystems selected

We have TRAUB TND 300 CNC lathe (2 axis) with System TX8 controller.The following problem has occurred:
At start-up in the morning, the Part 2 system button on the control panel illuminated. So far, No. 1 has always been lit. For some reason, we can’t get out of No. 2. The keyboard works, but Even if I press the button, it doesn't turn it off.
Can a parameter loss be the cause? How do I turn off System 2?
Thank you in advance for your response

how did you solve the problem?

The problem still hasn't been solved. The machine does not work because of the error.
