Thank you very much for buying an Universal Controller KS 45. The universal controllers KS 45 are suitable for precise, cost-efficient contol tasks in all industrial applications.
For that you can choose between simple on/off-, PID- or motorstepping control.
The process-value signal is connected via an universal input. A second analog input can be used for heating-current measurement or as external setpoint input. The KS 45 has at least one universal input and two switching outputs. Optionally the controller can be fitted with an universal output or with optocoupler outputs. The universal output can be configured as continuous output with current or voltage, for triggering solid state relays or for transmitter supply. Galvanic isolation is provided between inputs and outputs as well as from the supply voltage and the communication interfaces.
Applications
The KS 45 as universal controller can be utilized in many applications, e.g.:

5.5 Extended operating level
The operation of important or frequently used parameters and signals can be allocated to the extended operating level.
This facilitates the access, e.g. travelling through long menu trees is omitted, or only selected values are operable, the other data of the parameter level are e.g. disabled.
Display of the max. 8 available values of the extended operating level is in the second LCD line.
The content of the extended operating level is determined by means of the BlueControl select entry "Operation level" in the "Mode" selection menu. Further information is given in the on-line help of the engi neering tool.

5.6 Special change-over functions
In order to operate switch-over or -on functions needed more often via front, there are special functions available.
A-M
Switch-over automatic / manual-operation
ProG
starting / stopping the programmer
Func
Selection of different switching signals
Via the engineering tool BlueControl function can be adjusted in the operating mode (sig nals/logic). It can be assigned permanently to display 2 or the extended operating level.

5.6.2 ProG - start programmer
g
For A-M function handling, the switch-over source must be set to “Interface only” (Conf / LoGI / mAn = 0).
Manual operation ist selected via the È - key. The display element M is activated.
If adjustment of the output value is allowed (Conf / Cntr / mAn = 1), the output value is displayed, otherwise display element (M) blinks.
The Ì - key switches to automatic operation. The function can be taken into the extended operating level, or perma ­nent in display 2.
If the programmer function is activated, (Conf / Cntr / SP.Fn = 1/9), with this function the programmer can be started (run) or stopped (OFF) via front. With the È - key the programm is started and stopped with the Ì - key.
After the end of a programm the stop function (OFF) must be selected before the programm can be started again.

5.6.3 Func - switching function
The switching function Func takes the tasks of a function key. One or more signals switching at the same time, can be selected via configuration (Conf / LOGI/x=5)ausgewählt werden.
The switching function is set to on (= 1) via the È - key and to OFF (= 0) via Ì - key.
+
Example: The setpoint range adjustable by the user is limited from 20 to 100. Nevertheless it shall be possible to switch off the controller via front. This can be done by assigning Conf / LOGI / C.oFF= 5 and taking the Func - value into the extended operating level.

Function Func is not suitable for timer activation.
5.7 Selecting the units
The unit to be displayed is determined via configuration D.Unt. With selection “1 = temperature unit” , the displayed unit is determined by configuration Unit with the relevant
conversions for Fahrenheit and Kelvin. By selecting D.Unt = 22, display of any max. 5-digit unit or text can be determined.

6.1 Linearization
The input values of input INP1 or INP2 can be linearized via a table.
By means of tables, e.g. special linearizations for thermocouples or other non-linear input signals, e.g. a container filling curve, are possible.
Table “ Lin” is always used with sensor type S.TYP= 18: "Special thermocouple" in INP1 or INP2, or if linearization S.Lin = 1: “Special linearization” are adjusted.
w w
w
Non-linear signals can be linearized using up to 16 segment points. Each segment point comprises an input ( In.1In.16) and an output (Ou.1 Ou.16). These segment points are interconnected automatically by straight lines. The straight line between the first two segment points is extended downwards and the straight line between the two highest segment points is extended upwards, i.e. a defined output value for each input value is provided.
With an In.x value switched to OFF, all further segments are switched off.
+
g
Required: Condition for the input values is an ascending order.
In.1 < In.2 < ...< In.16.
For linearization of special thermocouples, the ambient temperature range should be defined exactly, becauseit is used to derive the internal temperature compensation.
The input signals must be specified in mV, V, mA, % or Ohm dependent on input type. For special thermocouples (S.tYP = 18), specify the input values in mV, and the output values in
the temperature unit adjusted in U.LinT . For special resistance thermometer (KTY 11-6) (S.tYP = 23), specify the input values in Ohm, and
the output values in the temperature unit adjusted in U.LinT.

The same linearization table is used for input 1 and input 2.
6.2 Input scaling
Scaling of input values is possible. After any linearization, measurement value correction is according to the offset or two-point method.
g
When using current or voltage signals as input variables for InP.x, the input and display values should be scaled at the parameter level. Specification of the input value of the lower and upper scaling point is in units of the relevant physical quantity.

KS 45 23 Input scaling
Parameters InL, OuL, InH and OuH are visible only with ConF / InP / Corr = 3 selected.
Parameters InL and InH determine the input range.
Example with mA: InL= 4 and InH = 20 means that measuring from 4 to 20 mA is required (life zero setting).
