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!
●meansthat ifthe corresponding safetymeasures arenottaken, apotentially
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.
TM 225/A Safety notes

Project engineering manual V1.06 9

CAUTION
Improper use of the assembly or the control system leads to irreparable dam-
age!
●Turn off the power supply before inserting or removing the module. Other-
wise, the module can be destroyed or undefined signal states can lead to
damage of the control system.

3 Description of the module
The TM 225/A is a temperature measurement module for use in the Kemro
automation system. This TM 225/A allows direct connection of PT 100 resist-
ance sensors. Up to 4 temperature measurement modules can be operated in
2- or 4 conductor technique.

3.2 Accessories
3.2.1 Connector strip
Input-/output signals: Standard male connectors with grid dimension 5.08 mm
The following female connectors can be used for the TM 225/A:

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 Connections and wiring
4.1 Connection of the shield-rail for analog signals
Fig.4-1: Connection of the shield-rail for analog signals
1... Shield rail
2... GND connection against 50 Hz field, length max. 1 m
4.1.1 Notes on wiring the analog lines
●Analog lines and reference current must be connected with a shielded ca-
ble.
●The shield rail must be connected to the GND terminal at one point.
●The shield must be placed on the shield rail as shown above.
●To attain optimum interference immunity, analog lines and reference cur-
rent should not be laid out parallel to strong interfering lines (e.g. lines of
converters for motors).
4.2 Temperature inputs
4 measurement inputs are available for the PT100 resistance sensors. These
can be operated in 2 or 4 conductor technique.

inputs is equipped with sensor failure monitoring.

With the 2 conductor measurement the reference current is applied via two
wire straps. The measurement result is influenced by the line resistance.

With the 4 conductor measurement the reference current is directly applied at
the sensor. This way the line resistance has no influence on the measurement
result.

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.
Theaddress switch is located onthe right side underneath thelower 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.
TM 225/A Configuration

Project engineering manual V1.06 17

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).
Configuration TM 225/A

Project engineering manual V1.0618

6 Operating behavior
6.1 Response by the measurement inputs
Internally the TM 225/A measures the temperature value every 1 ms. The slid-
ing mean value from the last 100 measurements (100 ms) is calculated every
2 ms. This value is available at the hardware end point system.TI0 for the
application.
6.2 Behavior during a fault
6.2.1 Response to module errors
In case of a module error an internal watchdog monitor will be triggered. The
module signals the module error to the CPU module or bus link module.
6.2.2 Sensor failure
The module identifies both a failure in the measurement line, as well as in the
reference currency line. The sensor failure is passed on to the CPU. Once the
sensor failure has been corrected the status "Sensor failure" will be automat-
ically reset.
