Liquiline CM442/CM444/CM448 Operation
Endress+Hauser 107
The pneumatic retractable assembly, e.g. CPA875, is activated by compressed air via a two-way
valve. As a result, the assembly assumes either the position 0 ("Measure" - sensor in medium) or
position 1 ("Service" - sensor in rinse chamber). Media such as water, acids or bases are supplied
via valves or pumps. Here there are two states: 0 (= "off" or "closed") and 1 (= "on" or "open").
The hardware required for "Chemoclean Plus", such as control valves, pumps, compressed
air supply, media etc., must be provided by the customer.
