Page 9: General Terms
General Terms 3.1. Purpose of use fig. 3.2. The control unit CU4plus IO-Link has been developed for the control of process valves in food processing industry as well as related industries. The CU4plus IO-Link control unit operates as interface between process control and process valve and controls the electric and pneumatic signals. - Page 10 The air supply of the control unit is equipped with an exchangeable air filter. Observance of the required compressed air quality is imperative. Please also see chapter 4.5 Technical Data. The number of the solenoid valves installed in the CU4plus depends on the valve actuators to be controlled. Single seat and butterfly valves and double seat valves without seat lift function require 1 solenoid valve.
