I had a serious problem on LC-20 Shimadzu HPLC DAD system. I downlaoed an old method and by accepting the new configuration to the new one now the system controller (an internal CBM 20A lite) give me an error while going up to 200 of pressure despite the same morning (before uploading the old method) the system was able to go up to 300.
Moreover, the code of error that I receive from the machine are [8003] and [0x23E]
What to do? Are some of you familiar with this kind of problem?
Thank you in advance.
