DL1 Restarts itself

[HH Tech]

Hello

My DL1 restart itself with a regular interval at 26sek

ie I swithch on the logger and after 26sek it starts logging, I turn logging of and after another 26 sek it starts logging and so on

This is regrdless of if car is on or not. If I let it keep logging it works allright with a correct file.

Autostart is disabled in config file.
Older unit serial around 300 green connectors at back

Any ideas?

It sounds to me like loop mode is enabled on the unit. I would try putting a standard configuration file on the unit and make sure that it is done with a reasonably new version of the configuration software so that the configuration definitely has loop mode on there.
If it was a hardware fault causing it to start I would expect it to start much faster than that.
