Is it possible to remove an EPC from flow shut down procedure of GC 8890? We are using EPC to stabilize sample line pressure at 3bar. When we are connecting new cylinders, we want to be sure that our pressure is slightly over 3 bar, so we set in the EPC to a higher pressure, and we use it somehow as a manometer. But during this procedure the 8890 shuts down the whole instrument due to low pressure. But there is no danger to any columns in the instrument as this EPC is controlling only the pressure of sample line. Is there any option to reprogram 8890 that it will not fall in the shut sown?
