[. . . ] With the PE 22 Controller, the EA 20, EA 30, EA 4@ and EA 50 electric actuators can be employed as follows: as a continuously adjustable positioner from 0. . 180°; in the process the aperture angle of the valve is measured continuously and compared with the setpoint as a process controller in conjunction with an external sensor and a reference input. The PE 22 Controller comprises two parts (PEV 22/ PEV @22 and PER 22) and is preferably installed in the actuator in the factory; it can, however, also be supplied in kit form (Fig. @).

The parameters are set as follows in the factory: Proportional range maximum (2@0%) Reset time maximum (1. 9 min) ¥ 45 The controller thus displays a predominantly proportional action. Three potentiometers are provided on the control unit (PER 22) for special adjustments: P@ for adjusting reset time P2 for adjusting the proportional range P3 for delaying the setpoint (remains at left-hand stop) If the setscrew is turned counter-clockwise: the reset time is shortened (I component is increased) the proportional range is diminished (P component is reduced) Control parameters Start of adjustment P max.
