Points of the characteristic:
For constant control gain ("linear characteristic"), you require:
Setpoint W,
Neutral zone
– Two-sided: "Start of the neutral zone" and "End of neutral zone"
– One-sided: only one of the two points
For range-dependent modulation gain ("segmented characteristic"), you require two-
sided control of all the points.
A point usually consists of two coordinates: an x coordinate (here = measured value)
and a y coordinate (here = actuating variable). You only need enter the y coordinates
for the optimisation points. For the other points, the CLM 153 sets the y coordinates
itself.
However, you cannot change the sequence of these defined points. It is, for example,
not possible to enter a larger measured value for the "Start neutral zone" than for the
setpoint.
Configuring the CLM 153
Please configure the relays in the following order:
1. Actuators
2. Sensor technology
3. Feedback (e.g. look-ahead control, position feedback with three-point step
controller, if available)
4. Characteristic:
In the user settings (seebelow) you switch directly to a controller simulation and can
check the settings made and change them if necessary.
To enter the menu, proceed as follows:

Select controller functions
Note!
You must activate the controller function after you have
configured the controllers in this menu branch.
Select the process type,
which describes your process.
1-s. = one-sided: The control is either "up" or "down".
Two-sided: The control is "up" and "down". You can only
select this function if you have defined two controllers
(in the "Contacts" menu and/or via the current output).
