Hi,

i have a new LOGO! FW V1.83.02.
I have set the correct time and later made a power-off / power-on.
The time setting was gone.
How ever i set the time, the setting always resets on power failure.

In the System Manual, 7/2022, A5E33039675-AK, chapter 4.3.3 it is written:
"Because LOGO! backs up the internal real-time clock, it continues operation after a power failure. The surrounding temperature influences the backup time. At a surrounding temperature of 25°C, the typical backup time of a LOGO! 0BA8 is 20 days."

Am i missing some setting?

Kind regards,
Adrian

Try power on for few hours and test again.

If it still reset of RTC then you may claim free replacement from your seller if it is within warranty perriod.
