Здравствуйте уважаемые. Ранее не работал с автоматикой Ремак и вот сбылось … . Шкаф VCB показывает аварии «акустический сигнал» и «проток воздуха». Перепробовал различные комбинации с диф.манометром фильтра, ничего не помогло. На счёт «акустический сигнал», вообще теряюсь в догадках. Ни в каких мануалах, это даже не упоминается. Может кто сталкивался с онными проблемами ?
