3. 2-stage Peltier cooler

Flue gas with a temperature above the dew point is sucked 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 (semiconductor cooling element) flown by a continuous
current is thermally connected with this body and with a second
metal body with cooling ribs and ventilation slots. The current thru
the Peltier element creates a heat transfer from hot to cold, drains
the heat of the metal body flown by gas and transfers it to the outer
cooling body. This heat is transferred thru ventilation to the
surrounding air.

The condensation issued by the heat loss of the gas drops in a
receptacle and is pumped out by a permanent working hose pump.
The sucking capacity of the gas conveying pump avoids a sufficient
dwell time of the gas with the condensate, so that wash out reactions
(NO

2+H2

O > H2NO3) do not take place. At the cooler outlet the gas
has a temperature of ca. 5 °C with a relative saturation of nearly 100
% relative humidity (corresponds to a water steam content < 7 g/ m

3

).

4. Heated sampling system

By using a heated sampling system (option) is possible to measure
water-soluble substances (NO

2

and SO2) without washout. A built-in
hot gas filter protects the instrument especially for long-term
measurements from fouling. The maximum exhaust gas temperature
when using the heated sampling system is 500 ° C.

Please note:

- Do not bend the tube

- Heated tube has to be cooled out after the
measurement

- Heated tube may not be folded too tight
(use the whole under case)

- Do not put the heated tube in water

- Clean or replace PTFE filter regularly

5. Converter (option)

The NO2 / NO Converter converts catalytically the NO2 content of
the sample gas into NO. For this purpose, the sample gas is passed
through a converter cartridge from stainless steel having a catalyst
filling. This conversion allows an indirect measurement of NO2
(switch function key <F1> at the control unit to toggle between NO

and NOx measurement).

Replace reactor cartridge

:

Replace the reactor cartridge if the conversion rate from NO2 => NO
falls below the required value. Changing the reactor cartridge is
possible without tools in a very short time. We recommend turning off
the instrument and letting cool down for approximately 1 hour before
changing the cartridge. This minimizes the hazard of burning. There
is also the possibility of changing cartridges in a heated instrument,
but the converter cartridge has a temperature of about 200 ° C.

The converter cartridge is hot! Touching may cause

severe burns! Wear suitable protective gloves and

protect the converter cartridge against access!

TECH

How to change the reactor cartridge:

- Stop sample gas flow (deactivate NOx measurement).

- Before opening the reactor fastener make sure that no toxic or
dangerous gases or components are provided within the gas way.
(Purge the tubes with inert gas or air).

- Turn the reactor fastener counter anticlockwise up to the end of the
thread.

- Pull out the fastener with the reactor cartridge carefully.

- Let the cartridge cool down if needed.

- Pull the reactor cartridge out carefully from the reactor fastener
(wear protective gloves).

- Replace new reactor cartridge to the reactor fastener.

- Push the cartridge carefully to the reactor opening and turn the
reactor fastener clockwise up to the end of the thread.

6. Power supply

The basic module of the ecom-J2KN

pro

TECH is delivered with
internal loading unit. The connection of the power plug is needed to
operate the instrument.

The control module of ecom-J2KN

pro

TECH is powered by 3 nickel­metal-hydride accumulators (type AA). In case of need, the
accumulators can be recharged by docking the control module to the
basic module.

Used accumulators can be returned to us or brought

to recycling stations of public waste disposal compa-

nies respectively accumulators selling stores!

7. Radio communication basic / control module

Thanks to the detachable control
module the basic module can be
monitored wireless. The basic module
can be unlocked as follows:

1. Press to unlock.

2. Tip control module forwards

3. Release control module from basic
module

The information exchange between
control and basic module is performed
via radio transmission (868 MHz) with
coverage of approx. 70 m (by free
sight). The quality of the radio
transmission is documented by a bar
indication in the main menu of the
instrument (long bar = good radio
communication).

By interruption of the radio
communication, an error message is
displayed. By persisting disturbances of
the radio communication, a cable
(option) can take over the transfer
(connection betwen socket DATA on
control unit and socket DATA on basic
module).

If the basic module is switched off and
the control module not, so the display
will show an error message inviting to
fix the control module in its docking
station (helps also not to forget the
control module). Observe this order, quit
with <ESC> and finally switch off the
control module.

11.1. Gas analysis

After warm-up and calibration phase, the instrument switches over to
the measurement mode. The gas measurement values can be
viewed on different display pages. Use the cursor keys to scroll the
pages.

With <F1> you can switch from the measured value display to a
menu or selected before (see chapter Adjustments). Possible menu
options are: Soot... Oil trace, Data processing, Adjustments, Control,
Fuel type, Standby, Purge, Eff. (C), Memory -> M, CLD NO <-> NOx,
WLAN, Pressure. Further you can switch with <F1> from any menu
back to the measured value display.
With <F2> you can print and store the measured values into the
intermediate memory at the same time.
With <F3> you can switch off the CO sensor, in order to protect the
sensor against too high concentrations (only required for
electrochemical CO sensor). The automatic disconnection will switch
off the CO sensor at approx. 2500 ppm (also for CO IR).
With <F4> you can switch from the measured value display to a
menu selected before (see chapter Adjustments). Possible menu
options are: Soot... Oil trace, Data processing, Adjustments, Control,
Fuel type, Standby, Purge, Eff. (C), Memory -> M, CLD NO <-> NOx,

To compensate a possible sensor drift, it is

important to calibrate the instrument with fresh

TECH

Page 23

Perform the measurement in the core stream of the exhaust gas
channel (probe placed in the highest gas temperature area).

A trend indication for T.Gas easies the core stream search. As long
as the display shows a + symbol, the measured temperature
increases, it means the probe tip moves towards the core stream. If
a - symbol is displayed, pull the probe out of the core stream and the
temperature sinks. If no temperature change is shown for at least 3
seconds, so the trend indication will be deleted.

, efficiency, losses, excess air and dew point are calculated
values. They can only be calculated if realistic values for the basic
parameters O

2

and temperatures are available. It must be

ascertained that:

O

< 20,5 % and T.Gas - T.Air > + 5 °C

are given. The dew point can only be calculated accurately if, in the
menu "Adjustments", the current barometric air pressure value has
been entered. This value cannot be determined by the ecom-

J2KN

pro

. If the gas temperature falls below the dew point (between
25 and 65 °C), ETA will be calculated with condensation. In the
display (C) appears behind ETA.
Correct measurement values are displayed first after a short delay,
necessary for the gas transport and the build-up of a stable
electrochemical reaction at the sensors. This time period lasts
approx. between 1 and 1.5 minute. For recording, printout and
evaluation wait until the values do not change anymore. If deviations
higher than 2 ppm still occur by the gas values, they can be due to
unstable pressure conditions in the exhaust channel.

11.3. Pressure measurement (option)

A trend indication for the draught conditions in the exhaust channel
can already be determined during the gas analysis. Nevertheless the
value for the chimney draught will not be stored together with the gas
values while pressing the key <Memory>.
Indeed the difference pressure sensor tends to drifts because of its
sensibility and, for an exact measurement it is consequently advised
to re-calibrate the sensor immediately before sampling and
documenting the value.

Access the menu while selecting the
sub-menu "Pressure". The current
value is displayed as well as the
instruction to adjust the zero point of the
sensor. Release hereto the draught
hose from the instrument for a short
moment and press <F4>. The sensor is
herewith re-calibrated.

Fix the draught hose again. The display
shows the exact measurement value
which can be stored while pressing
<Memory> and added to the previous
results in the intermediate memory. The
stored value is shown on the display.
Press <ESC> to quit the differential

11.6. Mean value measurement

By mean value measurement function measurements can be taken
in an adjustable time frame and mean values can be calculated.
Should the several measurement values or the mean value result be
stored a storage place has to be selected as described in chapter 7.
If the function “Store” is activated, based on this storage place all
measurements will be written consecutively on the next storage
places. If the function “Store” is not activated, the mean value result
can be stored on MMC with <Print> / „Memory -> M.

After run through fresh air calibration
the menu point “Mean value” can be
chosen. Before the mean value
measurement can be started the
settings for “Meas.time”, “Scanning”,
“Printer” and “Storage” should be
checked and if necessary be changed.
The meanings are:

-Meas. time = Time frame in which the
mean values will be calculated

-Scanning = time between the
measurements taken for mean value
calculation

-Printer = logging of measurements
taken for mean value calculation

-Store = all measurements for mean
value calculations will be stored

“Measurement time” and “Scanning” can be adjusted as follows:

-select menu point and confirm with <OK>

-with the numeric keys set the desired time:

0.01 = 1 sec. = minimum value

59.59 = 59 min and 59 sec. = maximum value

-confirm with <OK>

14.2. Automatic measurement

The configuration of the ecom-J2KN

pro

TECH with operation
securing, self-regulating additional components like the condense
trap, the gas cooler and the magnetic valve technique permits even a
long term operation of the instrument. By setting time intervals for the
measurement the instrument switches autonomously to fresh air
purge after the measurement phase (gas will be sucked via the
connection fresh air) and operates a calibration phase for the
sensors.

This cycle repeats itself until the
automatic measurement will be finished.
For setting the time intervals select from
the menu “Data processing” the menu
item “Automatic measu.”. The time
intervals have following meanings:

14.3. Data logger

Here a Data logger record (“Data logger” and key <OK> / on top
right on the display appears the disk symbol) can be started or
finished (just available when using the multi-media card). With
<Memory> you can interrupt and continue the record (only in gas
analysis). For each recording one file will be written on the card. The
files will be numbered consecutively (J2KDL-00.csv, J2KDL-01.csv
and so on) and can be transferred to PC with a card reader. The
length of a dataset is 500 byte which means that on a 32 MB card
64000 measurements could be recorded.

16. Maintenance tips

To secure the accuracy of your measuring instrument we
recommend the annual check by an authorized ecom partner. All
ecom partners are listed under www.ecom.de.The following advices
will be of help for the daily check and maintenance of single parts or
assemblies:

Pre filter heated head

Loosen the bayonet lock (press and turn it 90 °) and check the state
of the pre filter. It should be changed when the filter has a grey color
(number 2-3 of the soot comparison scale).

Fine dust filter

Screw off the cover of the gas cooler 1 and check the state of the
fine dust filter. Change it once the filter has a grey colour (number 2­3 of the soot comparison scale).

Do not use other sensors or feelers from other

manufacturers otherwise the TÜV approval

will not be valid anymore!

The ventilation filter should be changed, if the filter is grey coloured
(number 2-3 of the soot comparison scale). Remove for this the filter
holder with the help of a screw driver (recesses on the right of and
left side). Change the filter cartridge and fasten the filter holder.

Sensors
The sensors get calibrated with the reference gas fresh air by each
switch-on procedure. The state of the sensors is permanently
controlled by the instrument. If an error message is displayed during
calibration and cannot be eliminated despite several calibration
phases, so the instrument must be checked by a qualified and
authorised service centre.

SO

2

/NOx filter (only with electrochemical CO sensor)

In the tubing leading to the electrochemical CO sensor on the top of
the instrument there is a chemical filter for filtering SO

2

and NOx out
of the flue gas. The filter material is manganese-4-oxide granules
and should be changed once it has turned grey (colour change:
pink> brown> black> grey> white).

Probe and hose (only probe type SB)
Depending on the frequency of use, probe and hose should be
regularly cleaned in order to release particle deposits and to prevent
early wearing due to corrosion:

-Release the connections at the instrument and at the probe
grip to free the hose.

-Clean the hose (flow warm water in then dry respectively blow
water drops out).

Change printer paper roll

-Release the printer cover.

-If necessary, extract the paper rest out of the printer
("Adjustments" / "Paper feed" / <OK>).

-Remove the printer shaft and place the new paper roll on the
printer shaft.

-Insert the paper end in the slot (future printed side must be ahead).

-Press ("Adjustments" / "Paper feed" / <OK>) to transport ± 10 cm
paper thru the printer.

-Place the printer shaft back in the fixation.

-Insert the paper thru the cover of the printer compartment.

-Close the printer compartment while fixing the cover.

18. FAQ

Where do I find important instru­ment information?

The instrument shows the error
message „O2 sensor 0 mV“!

The instrument shows the mes­sage „Check required“!

The instrument shows the error
message „T-Gas“ or „T-Air“!

The instrument shows wrong or
inaccurately CO

2

values!

My instrument cannot be
switched on!

My instrument does not print!

Can I change the printout?

In the menu „Control“ all important instrument
information are shown (e.g. battery voltage,
sensor values, unit number, next service date,
operation hours etc.). With the arrow keys
stands you can switch to the second page.

The sensor must be renewed.

This message appears automatically every 12
months. Note: This is a recommendation to let
check the instrument. The instrument is how­ever still ready for use.

Possible reasons could be:

- Cable is broken (at the plug)

- T-Air sensor is broken

- Thermocouple is broken

- Cable is defective
Note: The error messages can be ignored at
the J2KN

pro

TECH by pressing „OK“. Calcula­tions that depend on these temperatures are
not implemented.

Possible reasons could be:

- O

2

is defective (CO2 values are calculated

from the O

2

values)

- Pump is not working correctly

- Leakage in the gas way

- Condensate trap / gas cooler is clogged

- Please check the mains cable

- Please check the fuse

- Please check mains connection (Plug socket
switched on?)

- Please load the accumulator min. 8 hours
(Accumulator could be over-discharged)

Please check whether the printer paper is
correctly inserted. The thermal printer writes
only on the thermally sensitive side. Please
use always the correct paper for the printer,
you will prevent defects at the printer. Please
make sure that the printer is clean (no chads
in the drive).

You can change the printout (Menu: Adjust­ments).
