2 Safety notes

2.1 Representation

At various points in this manual you will see notes and precautionary warnings

regarding possible hazards. The symbols used have the following meaning:

DANGER!

● indicates an imminently hazardous situation which will result in death or

serious bodily injury if the corresponding precautions are not taken.

WARNING!

● indicates a potentially hazardous situation which can result in death or se-

rious bodily injury if the corresponding precautions are not taken.

CAUTION!

● means that if the corresponding safety measures are not taken, a potentially

hazardous situation can occur that may result in property injury or slight

bodily injury.

CAUTION

● CAUTION used without the safety alert symbol indicates a potentially haz-

ardous situation which, if not avoided, may result in damage to property.

● This symbol reminds you of the possible consequences of touching elec-

trostatically sensitive components.

Information

Useful practical tips and information on the use of equipment are identified

by the “Information” symbol. They do not contain any information that warns

about potentially dangerous or harmful functions.

2.2 General safety instructions

WARNING!

● It is absolutely essential to observe the safety instructions in the system

manual.

● The module is defined as "open type equipment" (UL508) or as "offenes

Betriebsmittel" (EN 61131-2) and must therefore be installed in a control

cabinet.

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

Input-/output signals: Standard male connectors with grid dimension 5.08 mm

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.

Project engineering manual V1.1012

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

... 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

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

... 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.

Functional description

TM 240/A, TE 220/A for KeStudio U3

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

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.
