Engineer Training XL 1500 Safety System Confidential

Engineer Training Standard Requirements Both the machine and the Safety System are designed to meet the following standards: q CE - European Standard q UL - American Standard Confidential XL 1500 Safety System 2

Engineer Training Safety Loop on the Machine The safety system on the machine is based on a 24 VDC 1. 24 v loop comes from the 24 v P. S. 2. The loop passes through the head carriage E. S sensors (on the head carriage frame) right and left E. S, rear E. S laser relay and to the pneumatic panel. 3. The loop continues to the Over flow board and to the Ink system relay. 4. Ink board receives the 24 vdc and operate the ink system. 5. The Rip 2 CCB receives the 24 vdc and transfers it to the motion controller. Confidential XL 1500 Safety System 3

Engineer Training Safety Loop on the Machine (Cont. ) 6. The loop passes through the free fall service switch, if it’s in Service position – the drivers shut down and the loop continues to the laser Assy and making a shortcut between pins 14 and 21. 7. If the service switch in not in Service position – the loop continues and the +24 vdc passes to the K 3 contactor inside the PDU. 8. Together with the – 24 v, it comes directly from the 24 v P. S, enabling the K 3 contactor and the motion system to work. 9. A signal comes out from the PDU (K 3 contactor) to the motion controller, which, in turn, gives a signal if there is an emergency interrupt. 10. Right and left limit switches close a loop on the motion controller (inputs only – pins 2 and 10 on J 5) – if the loop is open – Print will not be performed. Confidential XL 1500 Safety System 4
