Hi.
Our S4C+ controller is having boot problems which are becoming more and more common. Now it booted fully to the system not until on the 14th attempt... First when these troubles began it usually went thru on the second attempt, then on the fifth, etc..
The status led on the CPU flashes red indefinitely. Also in the teach pendant it says "teach pendant communication lost". The manual says "the status led will continue to flash red if no OS or mass storage memory is found". On the same manual it also says "POST failure. Check main computer board, internal cabling and PCI boards".
I think one time the status led went from flashing red to flashing green (in between there was some hdd activity also) and this is the case when booting normally. But that one time the status led did not change to steady green like it should and the system did not boot up fully. The manual says about this: "Failed to start-up the system. Check flash disk (possible data corruption". I just wanted to write this also if it could help with troubleshooting.
Would there be any "easy" troubleshooting to do first? Could something as little as a bad controller battery have an effect?
If somebody knows what could be the cause, please help! Thank you very much!
