Important Hints
The ecom-EN2 should not be used for
continuous emission control!
The ecom-EN2 meets the requirements
of the DIN EN 50379 Part 2.
Observe the following minimum times in order
to get correct measurement values:
- 1 min. for sensors calibration at fresh air
- 2 min. for stable measurement values
Adjustments at burners and boilers
should be made only by specialists
who are familiar with these installations.
The following substances impair the
instrument´s operation:
- Solvent-containing vapours as:
- cleaning agents
- degreasers
- wax polishes
- adhesives
do contain
- Formaldehyde
1. Charge the internal accumulator regularly.
(an unused analyser should be charged at least 1 x per month)!
2. Never store the unit with a discharged accu!

3. Gas Cooler (option) / Model version ecom-EN2-P
Exhaust gas with a temperature over the steam dew point (35 - 65 °C) is
flown spiral via a long gas path thru a surface coated metal body with
good thermal conductivity. The gas radiates its heat to this metal body.
A Peltier element (semi-conductor cooling element) flown by a continuous
current is thermically connected with this body and with a second metal
body with cooling ribs and ventilation slots.
The flow thru the Peltier element creates a heat transfer from WARM to
COLD, drains the heat of the metal body flown by gas and conveys it to
the outer cooling body. This heat is conveyed thru a vertical forced
ventilation to the surrounding air.
The condensation issued by the heat loss of the gas drops in a receptacle
and is pumped out on request by a pediodically working hose pump.
By accumulator operation, the Peltier cooler can be switched off.
In the measurement menu press hereto <Enter>, select the menu point
„Peltier I/0“ and press again <Enter> (for Peltier cooler switch on, just
repeat this procedure).
The power needs of the gas cooler being high,
the cooling performance shall be reduced
by accumulator operation!
ecom-EN2 Page 7
4. Power Supply
The ecom-EN2 comes with an external charger. The analyser can
also be powered via the internal accumulator for a while (6 V; 3.8 Ah).
The accumulator recharge should be started when the instrument
requires to (acoustical warning and display indication). The
accumulator charging stand can be checked looking at the voltage
indication on the display (menu "Control" - Info key). The accu warning
is activated when the value „Accu“ is smaller than 5.7 V.
By 5.4 V the power operation via accu is no more possible; the instrument
must be further powered via the external charger.
5. Data Memory
The multi-media card enables the storage of punctual measurements;
the gathered values are written in a text file (J2KDV.txt). Data format
information is to be found in the appendix. The files can be transferred
to a PC via a card reader.
The following conditions must be fulfilled for using a multi-media card:
- minimal card volume 32 MB - max. 2 GB
- card formatted on 16 bit FAT
- SD or MM card from rbr
- PC with card reader from rbr
- or from the manufacturers Belkin and SanDisk
Used accumulators can either be returned
to us or brought to recycling stations of
public waste disposal companies
respectively to stores selling accumulators!

Card insert
Insert the multi-media card as shown.
Take care that the card does not stand
out and that it well hooks on.
6. Instrument Start
Once the instrument is switched on (key
<I/0>), the main menu is displayed.
6 sub-menus with the following functions
(non-visible sub-menus can be called up
while scrolling with the cursor keys) are
displayed:
Never pull out cards during
data record - data loss and
damaging of the data
carrier possible!
Always position the probe in the exhaust pipe
once the calibration phase is over!
Always use a filtering system as per our
recommendation for combustion plants
firing solid combustibles!

- Adjustments : Modify instrument adjustements
- Control : Check operation state of instrument
- Diagnostics : Read-out of firing automate

To perform measurements, select with the cursor keys the sub-menu
"Gas analysis" and confirm with <Enter>. The instruments starts then
a 1- minute calibration phase and the fuel types selection list is displayed.
The following fuel types are available:
Fuely types acc. to 1st BImSchV
Fuel oil (B)
Natural gas (B)
City gas (B)
Coke oven gas (B)
Liquid gas (B)
Use the cursor keys to select the desired
fuel type and confirm with <Enter>. The
instrument will then enquire if you wish to
use the data bank. If you want to assign
the sampled data to a specific plant, so
press <F1> (<F4> = no: measurement will
be performed without assignment).

7. Input or selection of combustion plants
To call up plant data already recorded or to create a new file, the following
possibilities are available:
Create new (is automatically selected
by first use of a MM card): To create a
new file, a numerical number should be
assigned.
Select „Create new“ and confirm with
<Enter>. Input a random number (max.
16 figures) using the keyboard:
- use the cursor keys <Up/Down/Right/Left> to select
the figure (selected figure outlined by a black background)
- press <Enter> to accept the figure (press <F2> to delete
the last figure if needed)
- repeat this procedure until the desired number is complete.
Example: "25.11.2008"
Tip: We suggest a date-related input to easily find the data
record later on via the search function.
After confirming with <F1> it is possible to enter a text via the keyboard
(max. 6 lines with 20 characters each) which is printed out and can be
used for data processing purposes. Proceed as follows:
- select text line 1 using the cursor keys <Up/Down> and
confirm with <Enter>
- select with <F3> the keyboard mode (4 keyboard modes
are available)
- select with the cursor keys <Up/Down/Right/Left> the desired
character (selected character outlined by a black background)
- press <Enter> to accept the character (press <F2> to delete the
last character)
- repeat this procedure until the desired text is complete.
