9.8.8 Controller configuration
The "controller configuration" is automatically carried out during selection of the application related
mode of operation (Base setup). The factory presets in accordance with the mode of operation are
based on many years of experience, which is suitable for many applications. Under special circum-
stances, these can be individually adapted (see menu group" setting ").
Controller Setup
P
Type of control
With pure P controllers (controller type P), the following described settings do not have any function.
If needed, the most suitable combination for the respective control system can be determined from these
proportions.
The control configuration (KP, KI, KD, TI) is identical for both control circuits in operation with two control circuits.
Fine adjustment is possible for each control circuit by the separate "Pband" setting.
L-BAL-E304-GB 2004
For the effect of the regulation there are two functions:
•
ON "Val > Set = n+"
for
Setpoint.
•
OFF "Val > Set = n+"
for
Setpoint.
Display for operation with two control circuits:
"1. Actual>Set=n" for control circuit 1
"2. Actual>Set=n" for control circuit 2
For special applications an external switch over of the control function is possible (see
IO Setup).

The type of control determines the method with which the controlled value behaves in
case of a difference between the target and current values. For this, the control
technology has standard algorithms, which consist of a combination of three methods:
Selection P, PID:
•
P
control (Proportional component, proportion of the absolute deviation)
•
I
control (Integral component, proportion of the sum of all deviations)
• D
control (Differential component, proportion of the last difference)
Display for operation with two control circuits:
"1.Controller type" for control circuit 1
"2.Controller type" for control circuit 2
