Sensor and compensation

Under Sensor Type, select the sensor you are connec­ting to the trans­mitter.

The compensation adjusts the connec­tion that you make.

When resistance thermometers, such as Pt, Ni and KTY sensors:

For thermocouples, the selection options for compensation change in internal, external, and manual:

Temperature range

Here you can set the desired measurement beginning and end of the measurement. The span, ie the area between the beginning and the end, shall not be less then minimum margin (see table). The possible settings are based on the operating temperature range of the sensors:

Output type and characteristics

At the output, there are 8 common standard signal ranges available:
0 to 20 mA, 0 to 10 V, 0 to 10 mA, 0 to 5 V,
4 to 20 mA, 2 to 10 V, 2 to 10 mA, 1 to 5 V.

The selected measurement range is linearly mapped to the output range. On the rising characteristic the begin of  measuring range corresponds to the 0/2/4 mA or 0/1/2 V, the end of measuring range to the 10/20 mA or 5/10 V.

The falling characteristic reverses the course. The transfer function of the converter is shown graphically in DRAGOset.

Error signalisation

The error signalisation defines whether errors will be left the output range. In this case, the output signal jumps to 22 mA, 11 V, 11 mA or 5.5 V, depending on the output selection.
Alternatively, the setting 0 mA, 2 mA, 4 mA or 0 V, 1 V, 2 V be chosen to signal the error, the output will remain in the range of measured values​​. This can be useful for example at a PLC input, that cannot handle signals out of range, the detection of the error then must be in the PLC.

DIP Switches

DRAGOset calculates from your inputs the correct DIP switch programming. This image can also be found in the PDF documentation and the printout again.

If DRAGOset is not connected with the cable to the transmitter, you can transfer the switch settings manually to the DIP switches of the transmitter.

Device diagnostics

With the menu item "Device | Diagnostics ..." call to a diagnostic screen. In this window, you get an overview of the current measured values ​​and messages of the transmitter.

This requires an online connection to the transmitter.

Simulation of input and output signals, commissioning function

With the menu item "Device | Simulation" call to a simu­lation screen of the device. In the simu­la­tion input and output values ​​can be simu­lated.

In addition, there is the commissio­ning function to check the following circuit parts with the complete mea­su­ring range. The commissio­ning function dyna­mi­cal changes the out­put value. The out­put slowly sweeps over the com­plete mea­sure­ment range, from the begin to the end value of the output range. The signal at 0 %, 50 % and 100 % of the range inserts a pause of a few seconds. It is possible to adjust the mea­sure­ment range in this check.

When you leave the simu­lator window, the simu­lation output remains active, if you do not switch off before. As a reminder, there­fore, the following window appears:

Wiring of Terminals

Depending on the selected sensor type and compensation changes the wiring of the transmitter. On this graph, you can see how the transmitter should be connected in this mode. If you move your mouse over the image of the transmitter, the terminal numbers are displayed.

Transfer function

DRAGOset shows the transfer function of the transmitter at the specified settings. You can see exactly the output value corresponding to the input signals. If you move your mouse over the curve, the input and output value is displayed depending on the position of the mouse pointer.
