3.2 Accessories
3.2.1 TE 220/A terminal temperature sensor (optional)
The terminal temperature sensor TE 220/A is used for the external cold junction
compensation. It must be used when the temperature lines have intermediate
connections.
Fig.3-2: View TE 220/A
The TE 220/A can be attached to the terminal in 2 different ways:
● Via adhesives
● Via cable binders
3.2.2 Connector strip

The following female connectors can be used for the TM 240/A:
Female connector Color Order no. Weidmüller
2-pole sw BLZF 5.08/2 SN SW - 170769
4-pole sw BLZF 5.08/4 SN SW - 170771
6-pole sw BLZF 5.08/6 SN SW - 170773
8-pole sw BLZF 5.08/8 SN SW - 170775
Information
Larger terminal blocks may be used to group multiple signals. The current
carrying capacity of the terminal block is thus, however, reduced (according
to derating curve of the terminal block manufacturer.)
The appropriate female connectors are not included in the delivery of KEBA,
but can be purchased from KEBA.
The technical data for the terminals are contained in the technical data sheet
of the manufacturer of the female connectors.
For further information see System manual.

4 Connection and wiring
4.1 Temperature inputs
There are 6 isolated measuring inputs available for thermocouples.
The following thermocouples can be connected to these inputs in both isolated
and in non-isolated configurations:
● Type J (Fe-CuNi) according to IEC 60584, measuring point temperature
-100°C to 700°C
● Type K (NiCr-Ni) according to IEC 60584, measuring point temperature
-100°C to 1,000 °C
● Type L (Fe-CuNi) according to DIN 43710, measuring point temperature
-100°C to 700 °C
The thermocouple type must be software configured.
Information
A thermocouple type that is incorrectly entered in the configuration can cause
measurement errors!
The resolution of the measuring procedure on the inputs is 14Bit.
Each of these inputs is equipped with sensor failure monitoring. If the meas-
uring range is undercut, a sensor failure is output.
All inputs are isolated against the logic and against one another.
The terminals are fitted with gold contacts. Consequently, the plugs are used
must have gold contacts.

... Counter and logic
Extension using thermo-compensation line
If the signal line to the thermocouple has to be extended, a thermo compen-
sation line must be used. This must be made from the appropriate material to
the thermocouple and appropriate plug-in terminal systems must be used for
the thermocouples.
No terminal temperature sensor may be connected in this case.
Information
With thermo compensation lines, the possible temperature measurement
range can be reduced (e.g. to 0°C to 200°C).
Extension using Cu-wire
If due to the reduced temperature measurement range or due to cost reasons
a Cu-wire is used instead of the thermo-compensation line, then a terminal
temperature sensor must be inserted to avoid gross measurement errors (TE
220/A) (measurement with external compensation).

5 Configuration
General information
A Kemro system needs data for the configuration of system performance, its
I/O-devices and interfaces. The system reads this data during the start-up op-
eration and allocates them to its components and devices.
Configuration data is created by included configuration tools or by editing con-
figuration files.
For further information to the configuration see the documentation of the in-
cluded configuration tool.
For further information to the configuration see the documentation of the in-
cluded configuration tool.
5.1 Setting the K-Bus address
The module is addressed via the address switch. A maximum of 12 modules
of the same type can be distinguished on one line.
The address switch is located on the right side underneath the lower cover (the
K-Bus plug is located underneath the upper cover).
Fig.5-1: Position of the address switch
1
... Address switch
On leaving the factory all modules are set to address 0 and both covers are
closed.
Information
Modules of the same type that are installed within the same line must have
different address switch positions. Different modules (e.g. analog and digital
modules) may have the same address switch positions.
Configuration
TM 240/A, TE 220/A for KeStudio U3
© KEBA 2011
Project engineering manual V1.1016
The two covers for the K-Bus plug and the address switch must remain locked
at the last module in the line (to protect against dirt and damage through elec-
trostatic discharge on contact).

6 Functional description
6.1 General functions for measuring temperatures with thermocou-
ples
6.1.1 Principle of temperature measurements
Fig.6-1: Temperature measurement
The thermocouple supplies (active) a voltage Uθ, which depends on the tem-
perature difference between the measuring point (w) and the comparison point
(u, terminal). k is the temperature coefficient of the thermocouple. It is de-
pendent on the material and the temperature. Therefore a change in the
thermo-voltage is not proportional to the temperature change. The software
executes the linearization.
To enable evaluation of the temperature at the measuring point, the tempera-
ture of the comparison point must be known. The latter is measured by a
terminal temperature sensor that is integrated into the module.
6.1.2 Temperature data sampling
Fig.6-2: Block diagram
1
... Counters and logic
The thermo voltage at the input terminals is amplified and converted into a
proportional frequency in the voltage-to-frequency converter. The measure-
ment period lasts 100 ms.
Due to the integrating measurement procedure used, any interference that oc-
curs at the AC line frequency (50 Hz, 60 Hz) is filtered out.

Project engineering manual V1.1018
Fig.6-3: Line frequency
6.2 Operating modes
Different software-configurable operating modes can be selected:
● Thermocouple measurement with internal terminal temperature compen-
sation (default configuration)
● Thermocouple measurement with external terminal temperature compen-
sation
6.2.1 Measurements with internal compensation
As the thermocouple measurement with internal cold junction compensation
constitutes the standard application it is set as default.
● With this measuring process the thermocouple is directly or indirectly via
a thermo-compensation line connected to the TM 240/A.
● The compensation of the terminal temperature is achieved with an internal
temperature measurement sensor.
● The measurement value is linearized and forwarded to the CPU in °C.
● No temperature measurement sensor is connected to the sensor interface.
Information
To ensure the highest precision it is recommended to mount the TM 240/A in
a calm air environment and away from power electronics, heating and venti-
lation elements.
6.2.2 Measurement with external compensation
In case the thermocouples are extended with Cu-wires, the temperature of the
terminal point (point of comparison) must be measured with the temperature
measurement sensor TE 220/A.
TM 240/A, TE 220/A for KeStudio U3
Functional description
© KEBA 2011
Project engineering manual V1.10 19
In this case, all temperature inputs must be attached at one terminal
point, because by using a TE 220/A all channels are operated with external
terminal temperature compensation.
The measurement value of the TM 240/Ais linearized (in °C values) and for-
warded to the CPU module.
At optimal installation of the terminal point a higher accuracy can be reached
as with internal compensation.
Information
To ensure highest exactness it is recommended
● to install the terminal point in a calm air environment and away from power
electronics, heating and ventilation elements.
● that the temperature measurement sensor is directly attached to the ter-
minal block or its immediate vicinity.
The thermocouple has to be attached via cable binders or adherents. Maxi-
mum length of data cable is 60m.
