1. General
1.1 Brief description
The WTR 190 is a temperature sensor in a wall-mounted housing. This makes it the
right choice for reliably detecting temperatures in rooms or in outdoor areas. Thanks
to the robust polyamide housing, the WTR 190 can also be used without any prob-
lems in blast freezers, deep-freeze warehouses and in aggressive ambient condi-
tions in industry. Optionally, the WTR 190 is available with KMU 100 or KMUS 100.
The KMU100 has a 4..20mA and the KMUS 100 a 0..10V output. The WTR 190 is
also available with DMU 50. The DMU has a 4..20mA output and a high resolution
OLED display.

3. Safety instructions
More important safety instructions can be found in the individual
chapters.
3.1 Intended use of the product
The sensor has been designed and built solely for the intended use described here
and may only be used accordingly. The technical specifications contained in these
operating instructions must be observed. Improper handling or operation of the in-
strument outside of its technical specifications requires the instrument to be taken
out of service immediately and an inspection by the manufacturer. When the instru-
ment is transported from a cold into a warm environment, the formation of conden-
sation may result in the instrument malfunctioning. Before putting it back into oper-
ation, wait for the instrument temperature and the room temperature to equalise.
The manufacturer shall not be liable for claims of any type based on operation con-
trary to the intended use.

E-Mail: [e-mail] I Internet: www.promesstec.com
Improper handling can result in considerable injury and damage to
equipment. The activities described in these operating instructions
may only be carried out by skilled stuff who have the qualifications
described below. Keep unqualified stuff away from hazardous areas.
For installation and starting of the flow-meter the stuff has to be familiar with the
relevant regulations and directives of the country and must have the qualification
required. They must have knowledge on measurement and control technology, have
to be acquainted with electric circuits, are capable of carrying out the work described
and can independently recognize potential hazards. Depending on the operation
conditions of the application they have to have the corresponding knowledge, e.g.
of aggressive media.
3.3 Special hazards
For hazardous media such as oxygen, acetylene, flammable or toxic
gases or liquids, refrigeration plants, compressors, etc., in addition to
all standard regulations, the appropriate existing codes or regulations
must also be followed. If you do not observe the appropriate reg-
ulation, serious injuries and/or damage can occur!
A protection from electrostatic discharge (ESD) is required. The
proper use of grounded work surfaces and personal wrist straps is
required when working with exposed circuitry (PCB, printed circuit
boards), in order to prevent static discharge from damaging sensitive
electronic components.
There is a danger of death caused by electric current. Upon contact
with life parts, there is a direct danger of death. Electrical instruments
may only be installed and connected by skilled electrical personnel.
Operation using a defective power supply unit (e.g. short circuit from
the mains voltage to the voltage output) can result in life-threatening
voltages at the instrument.
Residual media in dismounted instruments can result in a risk to per-
sonnel, the environment and equipment. Take sufficient precaution-
ary measures. Do not use this instrument in safety or Emergency
Stop devices. Incorrect use of the instrument can result in injury.
Should a failure occur, aggressive media with extremely high tem-
perature and under high pressure or vacuum may be present at the
instrument.

5.1.2 pmtKonfigTool - Connection between WTR190-DMU and PC
Loosen the cover of the WTR 190 to access the USB C interface of the DMU.
Connect the transmitter to the PC via a commercially available USB C cable.
ATTENTION: WTR 190 restarts after connection via USB! Now start the Windows
software "pmtKonfigTool".
To access the display, the first thing to do is to select the correct COM port. All COM
ports are listed in the "Port" drop-down list. The button updates the drop-down list.
As soon as a connection could be established successfully, the status changes to
"Connected" and the name of the connected device is displayed.
5.1.3 pmtKonfigTool –read
As soon as a connection with the DMU has been established, the settings are read
out and displayed in the software. The status, the temperature and the current value
are continuously updated. In addition, it is possible to press the "Read out" button to
read out and display all settings again.
5.1.4 pmtKonfigTool –write
To change the settings of the DMU, the desired values must be entered in the Win-
dows software and the corresponding options selected. However, the settings are not
applied until the "Write" button has been pressed. If the write operation cannot be
performed successfully, the old settings of the DMU are displayed again.
5.1.5 pmtKonfigTool - Factory settings
By pressing the "Factory settings" button, all parameters and settings are reset to the
delivery state.
Factory settings: Display: 0°
Fault current: activates
MeasuringRangeMin.: -30,0 °C
MeasuringRangeMax.: +80,0°C
5.1.6 Status
In total, the DMU can assume four different statuses, which provide information about
the current loop and the measurement of the current.
Ok: The DMU works flawlessly.
Cable break: There is a cable break in the connected PT 1000.
Underflow: The measured temperature is smaller than the smallest value
which can be can be transmitted with the 4..20mA interface.

promesstec GmbH I Niedersachsenstraße 4 I D-48465 Schüttorf I Tel.:[phone] I Fax:[phone]
E-Mail: [e-mail] I Internet: www.promesstec.com
Overflow: The measured temperature is greater than the largest value that
can be transmitted with the can be transmitted with the 4..20mA
interface.
Error evaluation: There is an error in the evaluation of the PT 1000.
5.1.7 Temperature
Under the "Temperature" tab, the currently measured temperature is displayed in real
time.
5.1.8 Display
Under Alignment, the orientation of the display can be rotated by 180°. Thus, the
WTR 190-DMU can also be mounted overhead (cable outlet upwards).
5.1.9 Fault current
Through the check box "Underflow/Overflow", which can be found under "Fault cur-
rent", the overflow and underflow function can be activated or deactivated. If the func-
tion is activated, the DMU will output a current of 20.5mA if the measured tempera-
ture exceeds the maximum temperature of the 4..20mA loop and 3.5mA if the mea-
sured temperature falls below the minimum temperature of the 4..20mA loop. If the
function is disabled, a current of 20mA and 4mA will flow in case of exceeding and
falling below. Regardless of the overflow and underflow function, a current of 21mA
always flows if there is a cable break in the temperature sensor (PT 1000).
5.1.10 4..20mA Current output
Under the tab "4..20mA current output" on the one hand the current of the current
loop is displayed in real time and on the other hand the scaling of the loop is configu-
red. For this purpose, the minimum temperature value for 4mA and the maximum
temperature value for 20mA must be specified.
5.2 Configuration KMU 100
If the WTR 190 is used with a KMU 100, the settings of the KMU can be read out and
changed via the Windows software "PXU01". The parameterization software kit
PXU01 is required for this. This contains the Windows software "PXU01" on CD, an
interface converter (USB adapter) and a plug adapter for the KMU. The configuration
of the KMU with the "PXU01" software is explained below.

5.3.1 Measuring range selection by DIP-switch
Four DIP-switches can be used to set 12 different measuring ranges. These are lis-
ted in the table below.
The query for the measuring range is permanent. Thus, the voltage supply does not
have to be interrupted after a change of the measuring range. The recognition of the
sensor (Pt 100/Pt 1000) is also done automatically during operation.
Attention: For Pt 1000 only the ranges 1..5 are available.
Jumper = 1: plugged
Jumper = 0: not plugged
5.3.2 Fine adjustment by correction potentiometer
As can be seen in the picture above, the correction potentiometer is located on the
top of the KMUS. This can be used for fine adjustment of the output voltage. A seal
secures the potentiometer against accidental adjustment.
