element

How it works:

Exhaust gas with a temperature over the steam dew point (35 - 65 °C) is drawn into a long gas path. Then, it is pushed through a metal coated surface with strong thermal conductivity. The gas radiates its heat to this metal surface. A Peltier element (semi-conductor cooling element) operated by a continuous current is connected with the metal surface and a second metal body with cooling ribs and ventilation slots.

The flow through the Peltier element creates a heat transfer from WARM to COLD. This drains the heat from the metal body and from the gas then transfers it to the outer cooling body. This heat is conveyed thru vertical forced ventilation to the surrounding air. The condensation created by the heat loss of the gas drops in a receptacle and is pumped out when needed by a hose pump. The Peltier cooler can be switched off in the following manner: In the measurement menu, press <Enter>, select <Peltier I/0> and press <Enter> again (To turn the Peltier cooler switch on, just repeat this procedure).

4. Power Supply

Used batteries can either be returned

to Ecom or taken to local recycling centers!

The Ecom-D comes with an external charger. The analyzer can also be powered via the internal battery (6 V; 3.8 Ah). The battery should be recharged as needed (Indicted by a warning sound and display light). The battery charging status can be by checked looking at the voltage indication on the display (menu "Control" - Info key). The battery warning is activated when <Accu> is lower than 5.9 V. At 5.8 V, the battery does not have enough power to operate the analyzer. At this point, the instrument must be charged via the external charger.

5. Data Memory The multi-media card enables the storage of measurements. The

measurement results are written in a text file (J2KDV.txt). Data format information can be found in the appendix. The files can be transferred to a PC via the memory card.

In order to use the memory card function:

- The card must have at least 32 MB of memory, with a maximum of 2 GB

- The card must be formatted on 16 bit FAT

- It must be either an SD or MM card from rbr

- The PC must have a card reader from ECOM, Belkin, or SanDisk

Connect the sample line to the <Gas Connection> plug, and position the sampling probe in the exhaust channel, so that the thermocouple is fully surrounded with the gas (see drawing).

Perform the measurement in the core stream of the exhaust gas channel with the probe placed in the hottest gas temperature area. As you move the probe toward the center of the exhaust, the display will show an up arrow, indicating an increase in the measured temperature. If the probe is pulled away from the exhaust, an arrow pointing down is displayed, indicating a decrease in temperature. If no temperature change is shown for at least 3 seconds, the arrow display will disappear, indicating the lack of change.

ues. They can only be calculated if values for the basic parameters like O2 and the temperatures are available. Make sure that:

O2 < 20.5 % and T.Gas - T.Air > + 5 °C

The current barometric pressure must be typed in (in the <Adjust- ments> menu) for the dew point to be calculated accurately. If the gas temperature falls below the dew point (between 25 and 65 °C), then efficiency will be calculated with condensation gain. In this case, a (K) is displayed after <Efficiency>. Correct measurement values are displayed after a short delay. This is necessary so the gas has time to reach the sensors and to build-up a stable electrochemical reaction for the sensors. This time period lasts approx. 1 to 1.5 minute. For recording, printout and evaluation wait until the values do not change anymore. If deviations higher than 2 ppm still occur with the gas values, it may be due to unstable pressure conditions in the exhaust channel.

If the measurement values are stable, press the key <Record> (disk symbol) to transfer the values in the intermediate memory (caution: store gas analysis, CO, O2 check and draft measurements separately).

They will be kept there for a later printout and, if need be, for a final data record storage.

If a printout of the values needs to be made as the measurement is taking place, simply press <F2> (the complete content of the intermediate memory will be printed).

ternal program. If the 4000 ppm limit is exceeded, a purging pump is activated which provides the sensor with fresh air. After sufficient purging time (X behinds CO disappears), the sensor can be reintegrated into the measurement system with <F3>. You can do this automatically by selecting <Yes> in <Adjustments> / <Internal> / <CO- Automatic>. The sensor can also be manually excluded from the measurement system by pressing <F3>.

8.2. Draft Measurement A trend indication for the draft conditions in the exhaust channel can

be viewed during the gas analysis. However, the draft will not be stored together with the gas values when pressing <Record> because the differential pressure sensor tends to drift. For an exact measurement, auto-zero this sensor just before sampling and document the value.

The display shows the current value as well as the recommendation to reset the zero point of the sensor. Disconnect the draft hose from the instrument for a short period and press <F4>. The analyzer will

then reset the sensor’s zero point.

8.3. Flow measurement (option)

This measurement can be done with a pitot tube. First, the pitot factor of the pitot tube must be entered by going to <Adjustments> / <Internal> / <Pitot factor>). After connecting the pitot tube to the analyzer, the zero point of the sensor can be set with <F4>. Enter the cross section of the flow channel with <F1>. This is needed for the calculation of the flow rate. After the pitot tube is positioned in the

The electrochemical sensors for gas analysis are subject to normal wear and tear as they age. Their accuracy may decrease as time goes on, depending on the gas concentration, the exposure time and the soiling grade of the sampled gas. The analyzer monitors the sensors and corrects drift. If the drift and the correlated measurement errors increase, an error message is displayed. In this case, the corresponding sensor must be changed by an authorized service center. The control menu has information about the current status of the sensors. Further information is can be seen on 3 display pages (use the arrow keys to scroll):

13. Maintenance Tips

To secure the accuracy of your analyzer, we recommend an annual check by an authorized ECOM service center. In the case of heavy usage (e.g. several hours of measurement per day, rough conditions etc.) service should be done more frequently. All ECOM service centers can be found at www.rbr.de.

warranty!

The following advice will be of help with maintenance of your ECOMD:

Change Fine dust filter (Instruments with gas cooler) Screw off the cover of the condensate trap/gas cooler and check the particle filter. Change it once the filter has a grey color (= number 2 - 3 of the soot comparison scale).

Ecom-D Page 29

Page 30

Condensate pad (Instruments without gas cooler)

Regularly check the condition of the condensate pad. It should be changed:

- If it is darker than no. 3 on the soot scale

- If it has expanded to the "MAX" mark To replace the condensate pad:

1. Remove hose from the cap and unscrew the cap

2. Unscrew the retaining bolt with spring

3. Replace old condensate pad with the new

4. Screw on retain bolt with spring again

5. Screw on cap and replace the hose to the cap

Sensors

The sensors are auto-zeroed in fresh air each time the analyzer is turned on. Their state is constantly monitored by the instrument. New sensors age as you use the analyzer due to normal wear and tear (oxygen sensor) and due to measurements exceeding concentrations beyond the nominal measurement range (toxic sensors). The output values of the sensors are (menu "Control"):

O2 approx. 20000 mV Others 0 mV (+/- 150)

If an error message is displayed during the auto-zero phase and does not disappear after several retries, the instrument must be checked by an authorized service center. The oxygen sensor must show a value of >7000 mV, otherwise it must be changed by an authorized service center. The CO sensor is protected against over-saturation by an internal program. If the limit value of 4000 ppm is exceeded, a second pump switches on and floods the sensor with fresh air.

can be reintegrated into the measurement system with <F3> (if you choose <Yes> in <Adjustments> / <Internal> / <CO-Automatic>, the CO sensor will begin measuring again automatically). The sensor can also be manually excluded from the measurement system with

<F3>. Probe and tubing

Depending on the frequency of use, the probe and sample line should be regularly cleaned in order to prevent particle deposit build-up and to prevent early wearing due to corrosion.

-Release the connections at the instrument and at the probe grip to disconnect the tubing.

-Clean it with warm water in then blow dry the water out

-Slightly grease the O-rings of the tubing connections from time to time with acid-free grease.

Change printer paper roll

-Release the printer cover (press lock downwards).

-If necessary, extract the remaining paper from the printer. To do this, select <Adjustments>/<Paper feed>/<Enter>).

-Remove the plastic tube of the previous roll.

-Insert the paper end in the slot under the transport roll (paper roll on the inner side facing you when inserting the paper).

-Feed approx. 3 cm paper through the printer (<Adjust- ments>/<PaperFeed>/<Enter>).

-Lay the paper roll in the corresponding space.

-Insert the paper through the slot of the printer compartment then cover and close the lid.

15. Calibration Procedure For best results, the calibration gas concentration should be as

close to the expected levels of emissions as possible. Because each sensor is linear through a nominal range, one calibration gas concentration can be used for a reasonably wide range of emission levels.

Fully charge analyzer:

Place unit on charge the night before you plan to use analyzer to

ensure full charge of battery.

Turn on analyzer and let warm up:

Switch on analyzer. Select Gas Analysis on main menu. Select

Fuel Type and press OK. Select No for Data Processing (if prompted). Instrument will complete auto-zero sequence. Let the analyzer run for 15 minutes to acclimate to ambient temperature. This is very important, as the accuracy of electrochemical sensors is dependent on a proper temperature setting. Switch off the analyzer and switch back on. Go to Gas Analysis mode. The instrument will complete autozero based on the proper temperature.

Calibrate your analyzer:

1. Select Control on the main menu. Swipe calibration magnet over

the Cal Magnet sticker, located above the ESC button. The analyzer is now in calibration mode. You will see real-time readings on the screen.

2. Connect calibration hose from the regulator to the gas inlet

(O2/CO) on the analyzer.

a. If you are using an on demand regulator, connect it to the gas

bottle and open gas bottle valve completely. The regulator will hold back the flow of gas until connected to the analyzer.

b. If you are NOT using an on demand regulator, adjust the flow

to match the analyzer pump draw.

Ecom-D Page 33

Page 34

3. You must check for air leaks before calibrating. Apply a gas with

0% O2 to check for air leaks (ECOM service dept. uses NO gas balanced in N2). Flow calibration gas for 3 minutes. Check that O2 reading is 0.0%. If it is reading other than 0.0 %, turn off gas and troubleshoot the source of air leak. Do not proceed to calibrate analyzer until air leak is corrected.

4. If there is no air leak, allow gas to flow for another 2 minutes (total

of 5 minutes). After the reading has stabilized, press up/down to place the arrow beside the target sensor and press OK to go to input mode. Input concentration of calibration gas using numbers on keypad. Press OK. The sensor has now been calibrated.

5. Allow the gas to flow for another 45-60 seconds. If it does not drift

more than 2% of the span gas, the calibration is steady and you may disconnect the gas. (If it does drift more than 2%, allow the

reading to stabilize and reset calibration. If this still doesn’t work,

call ECOM.)

6. If calibrating more than one sensor, disconnect the regulator and

reconnect to the next gas cylinder. Then flow calibration gas for 5 minutes, input calibration setting, & repeat step 5.

7. After all sensors have been calibrated, disconnect gas and allow

the analyzer to flush with fresh air for 10 minutes or until readings are below 10 ppm.

18. FAQ

Where do I find important instrument information?

How long is the life span of the sensors?

Which sensors can I exchange?

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“!

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

The life span depends on the operating hours and the instrument equipment. The life span of the toxic sensors (CO, NO, SO2, NO2) is affected by high gas concentrations and

a not sufficient purging. The life span for these sensors amounts to on the average between 4 and 6 years. The life span of the O2 sensor is independent of the operating hours

and amounts to approx. 2 years.

The following sensors are exchangeable:

- O2 sensor

- CO sensor (pre-calibrated)

- NO sensor (pre-calibrated)

- SO2 sensor (pre-calibrated / only together with CO sensor

The sensor must be renewed.

This message appears automatically every 12 months or after 250 operating hours. Note: This is a recommendation to 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 by pressing “En-

ter“. Calculations that depend on these temperatures are

not implemented. Possible reasons could be:

- O2 is defective (CO2 values are calculated from the O2 values)

- Pump is not working correctly

- Leakage in the gas way

- condensate trap / gas cooler is clogged

My instrument cannot be switched on!

My instrument does not print!

Can I change the printout?

- 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 always use the correct paper for the printer to prevent defects with the printer. Please make sure that the printer is clean (no chads in the drive).

You can change the printout (Menu: Adjustments).

Hint: If you have several instruments of the same type, you can locate an error by exchanging the accessories (probe, hose, temperature sensor etc.).

If further questions or problems should arise, please contact the next authorized service center.
