Description of System
6.2. Designs
6.2.1. Type 8792, positioner
The position of the actuator is regulated according to the position set-point value. The position set-point value is
specified by an external standard signal (or via field bus).
6.2.2. Type 8793, process controller
Type 8793 also features a PID controller which, apart from actual position control, can also be used to implement
process control (e.g. level, pressure, flow rate, temperature) in the sense of a cascade control.
The process controller Type 8793 is operated with a 128 x 64 dot matrix graphics display and a keypad with 4
keys.
The process controller is linked to a control circuit. The position set-point value of the valve is calculated from the
process set-point value and the actual process value via the control parameters (PID controller). The process set-
point value can be set by an external signal.
