11 Universal
controller
11.1 Overview
RMS705B provides 3 controllers with 2 sequential outputs each. The universal
controller can provide control to an absolute variable
or
differential variable.
Purpose
11.1.1 Enable the universal controller
Assign an input to the main controlled variable to enable the universal controller.

Main controlled variable ---, N.X1, N.X2, ..., internal analog
(analog values).

Control to an
absolute
variable
(1 sensor input)
Main controlled variable
Differential input
Xx (analog)
---
Control to a
differential
variable
(2 sensor inputs)
Main controlled variable
Differential input
Xx (analog)
Xx (same unit as main controlled variable)
The controller always uses the same unit as the main controlled variable.
Misconfiguration has the following effect:
