5.2.1. Type 8792, positioner with position control function
The position of the actuator is regulated according to the position set-point value. The position set-point value is
specified by an external uniform signal (or via field bus).
5.2.2. Type 8793, positioner with process control function
The positioner 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 positioner Type 8793 is operated with a 128 x 64 dot matrix graphics display and a keypad with 4 keys.
The positioner 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.
