Hi Gouw, it seems that you've been working for drager, isn't it?.
If so, do you have service manual for oxylog 2000?, do you know something about error #16 00 00 00 00?.
One of my favourites nightmares is the pneumatic circuit of one oxylog 2000 completly dissasembled. Does anyone have the schematic for pneumatics?.
Regards.
Jose.
