Diego termosolar Posts: 17 Rating: (0)	Good morning, Can anybody help me about an CPU error please. The CPU it´s linking all the leds. I tried restarting the CPU removing the 24V but the problem persist. I tried switching the CPU to Stop and then to Run with the same results. Any idea? Thanks and regards,

Here in forum have a lot of threads with a similar to your issue. Try it to find them using search ('all leds blinking'). If you ask the reason for that -Support RequestI am not sure even from there will receive an info.
