Can someone help me with our old machine we just buy it: Trumatic L2000 - with Rofin Sinar 500 laser?
We install the machine and we can move machine in JOG and REF mode. Still can't start the Laser.
I think we have problem with SIEMENS Sinumenrik System 8.
Please answer me what could be the problem:

We try to make some programs on Trumatic L2000, and we going according Operation manual we have.
See the pictures in attachment:
1. when we select MDI and press Part Prog. on screen was: "MDI%????N"
2. when we write %100 and press "Down scroll" then see the picture: "MDI new prg.jpg" - there is error 512 which is: "Entry Disabled". in manual for 512 is writen: "An input is only possible if Key switch is Enabled, or the Service Switch is in position 2 (Machine Parameters enter)" Where is the key switch and where is the Service Switch? Can some one tell me?
3. And also when we press AUTO button, it's showing Alarm RED LED and error code 3 on the screen - see the picture Error 3.jpg Way is that?

Also can you tell us what is the procedure of making Test Point Cut with the Laser. We dont have much experience with Laser cutting machines.

Thanks in advance.
