2. PRESENTATION
The TEMP-WM and TEMP-DM transmitter series have the best high accuracy and great stability temperature sensors. They convert the measured
values into linear 4 to 20 mA signals and optional 0 to 10 Vdc output can also be offered under request.
Since they are microprocessor-based devices, they can be configured using the TxConfig-USB Configuration Interface and SigNow or TxConfig
software or SigNow app.
3. INSTALLATION
3.1. MECHANICAL INSTALLATION
The TEMP-DM (Duct Mount) model transmitter should be installed with a flange. This flange is first screwed onto the duct wall and the transmitter
probe is then inserted into the flange central hole and locked. Figure 1 below shows flange dimensions and holes. Available in stainless steel or
polyamide 6.6.
Figure 1 –Mounting flange for TEMP-DM
The probe is made in stainless steel, with standard lengths of 150 mm or 250 mm:
Figure 2 –Model TEMP-DM dimensions
The model TEMP-WM (Wall Mount) was designed to be mounted directly onto a wall. With the cover off, the user can access the 2 fixing points and
the signal connector, as shown in Figure 3. The transmitter sensor capsule must be placed faced down in order to assure the specified accuracy
and protection level.
Figure 3 –TEMP-WM fixing holes and housing dimensions

NOVUS AUTOMATION 5/11
3.2. ELECTRICAL INSTALLATION
The transmitter can have 2 types of output signals: 1) Electric current from 4 to 20 mA or 2) Electric voltage from 0 to 10 Vdc. The output signal is
defined on purchase and cannot be later changed.
Figures below show the required electrical connections:
Figure 4 –4-20 mA model Figure 5 –0-10 Vdc model
LOAD represents the output signal measurement equipment (controller, register, etc).
The connection wires go inside the transmitter through to the cable gland mounted in the transmitter case.
3.2.1 INSTALLATION RECOMMENDATIONS
•Sensor signals conductors must go through the plant system separate from power leads (loop). If possible, in grounded conduits.
•The instruments must be powered from the instrumentation power supply circuit.
•In control and monitoring applications is essential to consider what can happen when any part of the system fails.
•RC filters (47 Ωand 100 nF) in inductor charges (contactors, solenoids, etc.) are recommended.
4. CONFIGURATION
When the transmitter is used with the factory setting, no further action is required, and the transmitter is ready to be installed.
When it is necessary to change the configuration of the equipment, you should use SigNow software, TxConfig II software, or SigNow app.
To configure the equipment through any of the software, you must connect the TxConfig-USB Configuration Interface (purchased from the
manufacturer or its authorized representatives) to the USB port of the computer used and run the selected software, as shown in Figure 6:
Figure 6 –TxConfig-USB Interface connections
To configure the device via the SigNow app, you need to use an OTG cable with the TxConfig-HRT Configuration Interface and proceed with the
recognition process (see SMARTPHONE CONNECTIONS chapter).
On NOVUS website, you can download the configuration software for free. To install it, simply run the file SigNowSetup.exe or the file
TxConfigIISetup.exe and follow the instructions in the installer.
The SigNow setup application can be downloaded for free from the Google Play Store or the App Store.

4.1 SOFTWARE AND APP
4.1.1 SIGNOW SOFTWARE
When running the SigNow software and connecting to the device, the following screen will appear:
Figure 7 –SigNow configuration screen
The bottom part of the screen displays information about the model, serial number, and firmware version.
The configuration screen is divided into 2 sections: General and Diagnostic.
In the General (see above) screen, you can configure the device by setting values and information for the following parameters:
1. Output type:Allows you to define the equipment output type.
2. Reverse output polarity: Allows you to reverse the output polarity.
3. Lower limite: Allows you to define the minimum desired temperature for the output type configured.
4. Upper limit: Allows you to define the maximum desired temperature for the output type configured.
5. Output status (Sensor failure): Allows you to establish the transmitter output behavior (upscale or down-scale) in the presence of a sensor
fail.
When selecting the Minimum option, the output current is < 4 mA (down-scale). Typically used for refrigeration.
When selecting the Maximum option, the output current is > mA (up-scale). Typically used in heating systems.
6. Zero correction: Allows you to make small sensor corrections.
In the SigNow manual, available on NOVUS website, you can get more specific information about the buttons and the process of diagnostics and
firmware update.

NOVUS AUTOMATION 7/11
4.1.2 TXCONFIG SOFTWARE
When running the TxConfig II software and connecting to the device, the following screen will appear:
Figure 8 –TxConfig software main screen
The fields in the screen mean:
1. Measuring range: Allows you to define the output scale for the input sensor. Program here the measurement Lower Value and the Upper
Value.
When the lower limit is defined with a value higher than the High Limit, the output current operates from 20 to 4 mA.
The values configured in these fields cannot be beyond the sensor measuring range. The minimal span value has to be observed as well.
2. Sensor failure: Allows you to establish the transmitter output behavior (upscale or down-scale) in the presence of a sensor fail.
When selecting the Minimum option, the output current is < 4 mA (down-scale). Typically used for refrigeration.
When selecting the Maximum option, the output current is > mA (up-scale). Typically used in heating systems.
3. Zero correction: Allows you to make small sensor corrections.
4. Device information: This field contains data that identifies the transmitter and is important during any inquiries to the manufacturer.
5. Read device: When selected, allows you to read the configuration present in the connected transmitter.
6. Apply: When pressed, allows you to send the configuration to the connected transmitter.
Note: The factory default configuration is (unless otherwise specified or ordered):
•Temperature span: 0 a 100 °C.
•0 °C of zero correction.
•Upscale when sensor fails.
Serial port configuration errors may occur when other software are sharing the same serial port. Close all serial port applications prior to
using the TxConfig software.

4.1.3 SIGNOW APP
When using an OTG cable and the TxConfig-USB Configuration Interface to connect the equipment to your smartphone and run the SigNow app
(see SMARTPHONE CONNECTIONS chapter), you must first enable the use of TxConfig-USB.
The interface will act as an intermediary for the connection:
Figure 9 –Using TxConfig-USB
After that, the app will recognize the equipment and show the
main screen:
Just click the Configuration button to show the main screen of
TEMP-WM or TEMP-DM Configuration section:
Figure 10 –Main screen
Figure 11 –Information screen
This screen shows information about the equipment, such as name, serial number, and firmware version.
When you open the Config section, you can configure the parameters displayed in the SIGNOW SOFTWARE section.
In the SigNow manual, available on NOVUS website, you can find more information about the buttons and the diagnostic process.

NOVUS AUTOMATION 9/11
4.2 SMARTPHONE CONNECTIONS
Smartphones with On the Go (OTG) technology can be directly connected to the device via the Micro-USB input. Using the TxConfig-USB
Configuration Interface, it is possible to recognize and configure the equipment by running the SigNow app.
To do this, as shown in Figure 12, you need to observe how to connect the OTG cable to the equipment:
Figure 12 –OTG cable
If you position the cable end incorrectly, it is possible that the device will not be recognized by the
application.

IMPORTANT
An identification label, on the transmitter body, shows the characteristics of this model.
No accuracy improvement results from narrowing the range for the 4-20 mA output. For example, the specified accuracy will be achieved for a
transmitter configured to a -50 to 100 °C or to a 20 to 40 °C range.
You can correct any sensor measurement errors with SigNow or TxConfig software or the SigNow application. You can connect the TxConfig
Interface to the transmitter even when it is connected to the process and operating. See software or app Zero Correction field.
It is possible that some temporary oscillations occur on the transmitter output when it is powered on and some changes are applied on its
configuration.
