Safeguard 400 Several Restarts
Hi, I have safeguard 400 at lab for testing with PM150V08, Subrack DSRF185M, SB171 and DSSR122.
My Problem is that every time I try to test PM150 , it works properly and after a time ,the processor Restarts and sometimes it Restarts Several times so I changed the processor Module ,DSSR122 and SB171 but the problem exists.
By check I found that I didn't tighten properly on the screws of the DSSR122 of the 0V and 5V at the rear of the Controller Subrack.
So can this cause the Processor to restart or the problem can be at the DSRF 185M ,knowing that the PM150 is seated properly at the Subrack?
Thanks a lot

Hello
We have had issues with old DSSR 122 where they get hot and reach the current limit and shuts the 5 V DC voltage, intermittently, causing reboot.
Have you tried with a new DSSR 122 ?
The recommendation is to replace these on a regular interval due to dried out capacitors and increased voltage ripple.
