I have an ATL HDI 5000 issue - need help - system suddenly stopped working - heard a snap inside just prior to failure . Have been receiving message system will shut down for high temperature lately . On the input board 5and 6 are lit - on PSM no over current light - the other one on . checked the voltage at the pins 0 - is that a PSM complete failure ? or is there a reset or something a fuse to change . help appreciated.
Thank you
Since those two LEDs are lit on the input board, then the internal fuse of the input board is good and the 155 VDC is being sent to the card cage. The PSM has the LED lit, which indicates that the 155 VDC is present there. Since this is a good in/bad out situation, I would suspect that the power supply is bad. One other thing to check though is the input capacitor. On the back, to the right of the input board, you will find a large silver capacitor. Its job is to bump up the input AC. If it fails, there is not enough power to run the system. It rarely fails, but you should check it.
it is very annoying to remove that capacitor - it is easier too hook up another one out of the chassis to test . anyone has that capacitor specs please ?
Hi Garald,
All the voltages - + 15V - + 12V and other are formed by the corresponding modules.
The voltage HVDC = 175V is supplied to each module through fuses = F1 - F8.

Good I had that in thought but it seems to be so robust I was not convinced - will see that today .

Hello Garald,
can you send me a pictures of message system
and from PSM of LED HVDC OK & OVP TRIG?

do you have a picture locating those fuses - or some indications
