Operation

RCP 10 and RCP 11

The transducer at connection 4 converts the control variable into the pneumatic standard signal 0,2…1,0 bar (equivalent to 0…100%) within its measuring range. This actual-value signal xi4 is compared with the fixed setpoint Xs. If there is control deviation, the output pressure y is adjusted until the actual value is equal to the setpoint (PI-control). With a pressure of 0,2…1,0 bar at input 6, the setpoint can be set remotely from 0…100%. The internal setpoint setting then functions as a minimum limitation.
A restrictor (Ø 0,2 mm) for supplying the transducer is fitted at connection 4. The signals from the transducer and the output pressure can be checked via the M4 measuring connection or shown via the manometer.

RCP 11: additional functions

The transducer at connection 5 converts the command variable (e.g. outside temperature) into the pneumatic standard signal 0,2…1,0 bar (equivalent to 0…100%). This signal (xi5) is fed to the command circuit which, together with the setting parameters FF and E, creates a program for the setpoint shift of the following PI-controller. The characteristic for the influence E can be placed in any of the four quadrants.
Because the outside temperature is often fed to more than one controller, the transducer at connection 5 must be supplied by a separate (Ø 0,2 mm) restrictor.
