PM810 losing their configuration at restart

[sesa97267_bridg]

Hi,

I have 2 PM810 which are not permanently powered and they sometimes lose their configuration (communication parameters, language etc..) at restart.

Do you have history of such a phenomenon or any clue why it could happen?

Are the settings stored in flash memory or through battery system? if so, is there a way to check battery status/capacity?

Best regards,

[Adrian_Dicea]

Did you get an answer from Tech Support on this issue?

Hi Adrian,

nothing so far. As they do not have the latest FW revision (they have n-1 version), I am considering suggesting them to upgrade and see...

Any other idea on your side?

The PM810 has no internal battery.  It will definitely lose the clock, but I never experienced it losing the program.

We have encountered configuration loss after restart in commissioning stage of several projects in Taiwan as well.

Please also inform me if there's a fix.

Thanks

Dear Chen,

the case was closed because I could not provide sufficient information on what was happening.

You should contact Power Technical Support and open a case also, that may help deeper investigations if we are several users facing this issue,
