Note: A con iguration o the parameters via DIP switch (see 3.2 (1) DIP switches) can only be done i the DIP
switch 12 is set to OFF.

4.1 Setting the measuring range
You can adapt the respective desired measuring range o the di erent sensors to your application via DIP
switches (see 3.2 (1) DIP switches).
The respective setting options can be ound in the ollowing table:
Scaling of the measuring range
Variant 5000 ppm
DIP switch position 5
0… 5000 ppm OFF
0… 2000 ppm ON
Note: For the variant 0... 2000 ppm the possibility of a measuring range scaling does not exist.
4.2 Setting the output signal
You can adapt the respective desired analog output to your application via slide switch S1 (see 3.2 (3) Slide
switches) and DIP switch 7 (see 3.2 (1) DIP switches). The respective setting options can be ound in the
ollowing table:
Output Output signal Slide switch position DIP switch position 7
CO2 (1)
0… 10 V S1 rechts OFF
2… 10 V S1 rechts ON
0… 20 mA S1 links OFF
4… 20 mA S1 links ON
5 Setting and configuration via software
Customer so tware is available or the eel transmitter, which can be used to con igure various parameters.
Proceed as ollows:
5.1 Installation of the software
• Download the " eel con iguration so tware" in the download area o the web page o the eel series o
transmitters: https://measure. sm.ag/en/home/products/multi-transmitter/ eel-multi
• I you do not have .NET 6.0 Desktop Runtime (v6.0.12) pre-installed, install it be ore using the
application: (Download link .NET 6.0 Desktop Runtime (v6.0.12))
• Open the application "Con iguration so tware eel (exe)".
• Under certain conditions, a Windows popup window will appear warning about using an unknown
so tware. Click on "More in ormation" and the button "Run anyway".
5.2 Commissioning a feel transmitter
5.2.1 Connecting the transmitter
• Connect the input lines to the designated clamps (see 3.2 (4) Clamps or Input and Output) to supply
the transmitter.

Version: 1 FSM AG │ Erich-Rieder-Str. 2 │ 79199 Kirchzarten www. sm.ag
Operating instructions eel FC Page 5 o 7
• Set DIP switch 12 (see 3.2 (1) DIP switches) to ON to enable con igurations via so tware.
• Connect the device to the PC with a micro USB cable type B (see 3.2 (7) USB plug).
• A new COM port appears on the start page o the so tware.
• Click on the "Connect" button next to the newly appeared COM port.
• The menu o the con iguration so tware opens.
5.2.2 Reading out the transmitter data
• Via the menu item Home, the data o the transmitter such as article number, so tware version,
hardware version, type code and previously con igured options are displayed.
• It is possible to assign a customer-speci ic number or unique identi ication o the transmitter via the
"Customer serial number" ield.
5.3 Configuration of the transmitter
5.3.1 Measurement range
• Open the "Sensors" menu item.
• Change the values o the measuring range in the "Measurement range" ield according to your
application by entering the min and max values in the corresponding text ield or moving the min and
max bars on the slider.
• The output signal is then scaled according to the set measurement range, i.e. or a 0-10 V output, 0
volts corresponds to the set min value and 10 V corresponds to the set max value. The same applies
to the other possible output signals such as 2-10 V, 0-20 mA and 4-20 mA.
• By clicking the "Send" button, the settings are accepted and the con iguration is sent to the
connected transmitter.
5.3.2 Adjustment
• Open the "Sensors" menu item.
• Fixed adjustment points are available at which the transmitter can be adjusted. The set points are
displayed as text within the corresponding buttons "Set [VALUE]".
• To adjust the sensor at the respective adjustment point, this value must be generated with a suitable
re erence, e.g. in a nitrogen chamber. As soon as the re erence has stably adjusted the adjustment
point, the transmitter can be adjusted at this point by pressing the respective button, e.g. "Set 0
ppm". I the value o the transmitter is >10% outside the setpoint, the buttons are grayed out and an
adjustment is not possible to avoid operating errors.
5.3.3 Output signals
• Open the „Outputs“ menu item.
• Change the values o the output in the "Voltage range" ield to scale the voltage output or in the
"Current range" ield to scale the current output according to your application. Using the slider,
voltage and current output can be scaled in parallel.
• The new output scaling is sent to the transmitter via the "Send" button

Operating instructions eel FC Page 6 o 7
• The igure below the con iguration levels shows to which terminals the output lines should be
connected
Note: Switching between current and voltage output must be done physically on the board via slide switch S1
(see 4.1) (right position = voltage output; le t position = current output).
5.3.4 Switching outputs (if available)
• Open the "Outputs" menu item.
• Select the output Output 3 or 4 to con igure the open collector outputs.
• In the next step, select whether you want one or two switching thresholds.
• With a switching contact, the output is HIGH as soon as the set threshold is exceeded. When the
threshold value is undershot, the output is LOW. With two switching contacts, the output is HIGH as
long as the measured value is within the switching window and LOW as soon as it is outside the
switching window.
• This logic can be inverted via "Invert the logic" = "Yes".
• Via the slider, the threshold values can be set in percentage steps o the measuring range end value,
whereby the green area marks the "HIGH" and the red area the "LOW" range.
• By clicking on the "Send" button, the settings are accepted and the con iguration is sent to the
connected transmitter.
5.3.5 Display image
• Open the "Display" menu item to con igure the representations on the display.
• The "Color Theme" ield can be used to adjust the colors on the display according to your
requirements.
• Click on the "Send" button to apply the settings and send the con iguration to the connected
transmitter.
6 Service and maintenance
6.1 Adjustment
I necessary, the transmitter can be adjusted to eliminate nonlinearities or zero o sets. Proceed as ollows:
• Using a suitable re erence, generate the value o the respective set point (see table below) at which
you want to make an adjustment.
• Press either the "Down/Zero" or "Up/Span" button (see 3.2 (6) Buttons). Which button has to be
pressed or which set point can be seen in the table below.
• The transmitter is now adjusted at the desired point. I the current measured value is +/- 10% outside
the set point, no adjustment is made to avoid alse conditions.
