Okuma VR40 2 Alarm B 2336

[Vulcanalia]

Dear friends,

We recently purchased a Okuma VR40 2 Mill, but got stuck at a alarm which we can not get around.
It states 2336 Alarm B. "Falcher T-befehl 2". The language is german but it would translate in "Wrong t command".
I think it has to do with the tool changer.
It did execute programs before but now we keep getting this alarm.

Any help appreciated!

Best regards,
Paul
