Preface
Dear customer,
Thank you for selecting our COMTEC® 6000 as your InSitu Flue Gas Oxygen/Combustibles (COe*) measuring system.
ENOTEC has been producing its world famous OXITEC® Oxygen Analysers
for more than 30 years, and now our COMTEC® Oxygen/Combustibles
(COe) measuring system enhances our product line. ENOTEC are committed to total quality and performance and we have continuously enhanced our
products to integrate various additional features and functions. In this package, the electronic unit uses the very latest Microprocessor Technology,
making the SME5 electronic unit one of the most advanced and up-to-date
monitoring units permitting you to reduce your maintenance & fuel costs to
achieve an increased measuring accuracy with more operational reliability
due to new monitoring functions.
In our COMTEC® 6000 probes you will find the Zirconium Oxide measuring
sensor which is gas-tight sealed in place using a special process and technique developed by our company. This leads to a considerably increased
service life as compared to "glued or cemented" measuring sensor that has a
tendency to leak or crack during operation. The O2 sensor is a proven gastight design providing greater measuring accuracy, durability and longer
working life with the experience of more than 30,000 installations. For COe
measurement, we have integrated a high temperature MXP- sensor.
All ENOTEC instruments are thoroughly tested in the factory and are subject
to a strict ISO 9001 Quality Assurance procedure. Therefore, with the correct
installation, the operation of the COMTEC® 6000 InSitu Analyser System is
very easy to use and user friendly. It will provide you with many years of operation with perfect measuring results.
Please read this manual carefully and follow the instructions as directed. If
you have any questions, or you are unclear about any aspect of the installation or operation, our Service Department, regional sales offices or approved
distributors will be pleased to assist. The factory contact points are Tel: +49
2264-45780 or Fax: +49 2264 457831. You may also visit us at our website

Warranty
ENOTEC
2 YEAR
WARRANTY
ENOTEC warrants that the equipment manufactured and sold by it will, upon shipment, be free of defects in workmanship or material. Should any failure to conform to
this warranty become apparent during a period of two years after the date of shipment, ENOTEC shall upon prompt written notice from the purchaser, correct such
nonconformity by repair or replacement of the defective part or parts. The purchaser
is not entitled to claim any other legal remedies on the basis of this warranty. Please
refer to the complete ENOTEC warranty policy for details.
ENOTEC does not warrant equipment supplied by it against normal deterioration.
Corrosive gases and solid particles may cause damages and make a repair or a replacement necessary as a consequence of normal wear and tear during the warranty period. The COe sensor is such a product, with a guarantee limited to one
year.
All ENOTEC products and systems which do incorporate a heated sensor must be
operated under continuous conditions. If the heater power is switched off and
on regularly, more thermal stress for the probe heater, the probe thermocouple and
the ZrO2 cell will cause shorter life time. If it is not possible to operate the heated
equipment continuously for a longer period of time, please contact ENOTEC for
technical advice.
Note: When installing the equipment, the customer must ensure that all necessary
supply lines are connected and the operating temperature of the probe is reached.
Experience has shown that products installed but not put into operation may be
damaged by the process or by external influence. ENOTEC will not accept any responsibility for such damages.
ENOTEC does not warranty ENOTEC products and systems which have been combined with products or components from suppliers not approved by ENOTEC (e.g.
probe signal cable, probe flange gaskets).
When installing and commissioning ENOTEC products and systems, you have to
use proper tools. If there is any damage due to the use of wrong tools, ENOTEC will
not accept any responsibility for damages.

Information on the CE-Certification
After having completed and successfully passed EMC-tests, the complete
ENOTEC InSitu Analyser System - consisting of measuring probe, electronic
unit and probe signal cable - has a conformity certificate.
If parts of this system are operated with products not supplied or approved
by ENOTEC, the CE-conformity is no longer valid.
Likewise, all warranties are void if the system is operated in a configuration not authorized by ENOTEC!
Note
The enclosed ferrite sleeves must be placed over the terminal leads of the cable (see wiring chapter 2.5.2). The CEconformity is void if these ferrite sleeves are not fitted!
Note
The ground (Earth) connection must be installed thoroughly
using the correct cable of at least 1,5 mm² minimum. It is
very important that the equipotent bonding is installed correctly.
Please note that some electrical devices (e.g. frequency
converter etc.) close to the system can create considerable
electrical disturbance and instability. So for normal function
of the COMTEC® 6000 InSitu Analyser System it is important that these devices be installed away from the system
and in accordance with the manufacturer’s installation notes
and guidelines.
Please do not run the probe cable near power supply cables, or near motors and their cables, as frequency converters control them because this could cause interference effects. If possible, do not cross the cables because this could
interference effects. However, if this is unavoidable please
make sure that these cables are only crossed at right angles.

Intended Use
Note
The COMTEC® 6000 InSitu Analyser System is a system for
measuring the oxygen concentration and the concentration
of COe* in flue gases. For reasons of safety and the possible occurrence of accidents, unauthorized conversions and
modifications of the system are prohibited.
Warning
The minimum concentration of O2 in flue gas should, under
normal process conditions, not be less than 0.5%. The system must not be used for the determination of the O2/COe
content of gases, whose lower explosion limit (LEL) can be
exceeded. There is danger of explosion, since the measuring cell temperature of the O2 measuring cell is
840 °C
(1544 °F).

Page 12 of 80
1.10 General Safety Instructions
The COMTEC® 6000 InSitu Analyser Systems may only be operated by authorized trained skilled persons. For reasons of immunity to interference, it
must be ensured that the connection between measuring probe and electronic unit is only made with the ENOTEC probe signal cable and pneumatic
tubing.
The O2/COe measuring probes supplied by us may only be used with
ENOTEC electronic units or with compatible electronic units approved by
ENOTEC.
Important
Under no circumstance may the measuring probe be directly
connected to the 230V main power, as this will immediately
destroy the probe heater element!
1.11 Corrosion
The probe may only be used in flue gases whose composition is uncritical
regarding the corrosive effect on the materials used. With increased risk of
corrosion, regular checks at suitably short intervals are necessary.
1.12 Safety Hazards
Warning – Hot Surface
During operation, the temperature of the probe filter head and
of all parts exposed to flue gas is 150 °C – 500 °C (302 °F932 °F). Direct contact with the hot parts for dismantling or
maintenance will cause severe burns!
The probe may only be removed with heat-insulated gloves.
Before removing the probe, always switch off the supply voltage to the electronic system. After removal, store the probe
in a safe, protected place and wait until it has cooled downs
below 35 °C (95 °F).

2.13 Insulation of the Protection Tube outside
the Duct
Note
If a cooling protection tube is used, the part of the protection
tube outside the duct wall must be insulated or heated if
necessary, to prevent flue gas temperature inside the probe
below the dew point.
Electrical heaters are available from ENOTEC as accessories. The bolts of the probe flange must remain accessible.
The probe protection tube has to be
insulated
outside the duct to
avoid temperatures
below the acid dew
point of the flue gas
inside the probe.

Description of the Electronic Unit for
COMTEC® 6000 InSitu Analyser Systems
General Description of the Function
The SME 5 electronic unit is designed for connection to one O2/COe measuring probe. The mV signal of the measuring sensors are amplified and then
converted into a digital signal in the electronic unit (14 Bit converter). The µprocessor linearises and corrects the signal according to Nernst’s equation
of the O2 measuring sensor. The O2 value is then displayed as a percent
value and the mA output has an isolated 4 - 20 mA output.
The COe measurement is achieved as a mV measurement of the heated
COe sensor. The COe sensor temperature is controlled. The SME 5 microprocessor converts this voltage into a digital signal and displays ppm COe
and drives the 4-20 mA output.
As a standard, the electronic unit has two O2 measuring ranges and one
COe measuring range. These measuring ranges can be freely defined in
their initial and/or final value (within permissible system-related limits). The
second O2 measuring range can be switched remotely 3.9.1 on page 38).
The second O2 measuring range is signalled by a relay contact to the outside. The electronic unit is completely self-controlled. Any system errors occurring are displayed as clear text with an online help function for information.
The COMTEC® user Interface permits intuitive operation by means of a selfexplanatory menu structure.
Until the COMTEC® 6000 probe has reached its operating temperature, the
System Error contact is open and the display shows that the probe is heating
up. The progress of the heating phase is shown by a bar indicating the current probe temperature. During the heating phase, all system parameters, as
well as (actual) values in the corresponding menus, can be selected on demand from the keypad.
When the probe has reached its operating temperature and is stable within ±
0.1 °C, actual measurements are read, the System Error contact closes and
the standard actual value display appears on the screen. The system is now
ready for O2/COe measurement.

Page 27 of 80
3.3 General operating instructions
The electronic unit is operated by means of four soft keys and a numeric
keypad. The functions of the soft keys always adapt to the current menu
window. The numeric keypad serves only for entering numerical values.
The ENOTEC user interface is designed for intuitive usage of the electronic
unit. This means that as a rule there is no need to study the instruction manual during operation.
Figure 16 Front panel of the COMTEC® 6000 electronic unit after the COe sensor is enabled
By pressing the soft keys [menu/cal.], [values] or [parameter] the respective
menus can be obtained. In each of these menus various options can be selected from a list using the soft keys [] and []. If there are more than 4 options, this is indicated by an arrow on the right hand side of the menu list.
This arrow indicates that there are more options to follow. The option which
can currently be selected has a black background and light letters and one
can get access with the soft key [enter].
The main display provides the information about the actual O2 value in (Vol.)
% and the COe (CO and other combustible gases) value in ppm. You will
also get the information about the adjusted measuring range (on top of the
bar graph: left number: minimum level of the adjusted measuring range; right
number: maximum level of the adjusted measuring range.
If the COe value is out of range, this status will be indicated by an arrow (see
Figure.

Start-up of the COMTEC® 6000 InSitu
Analyser System
Important
Before the COMTEC® 6000 InSitu analyser system is powered
up make sure that the conditions comply with the following
points:
• Does the line voltage correspond with the voltage shown on
the type label of your COMTEC® 6000?
• Are all electrical connections made in accordance with the
instructions in this manual?
• Are all pneumatic connections made correctly and gastight
to prevent the probe from ingress of ambient air?
• Is the COMTEC® 6000 probe installed in a flue gas that
corresponds with the probe specification?
• Do the ambient conditions for the electronic correspond with
the specifications for the electronic unit?
3.5 COMTEC® 6000 Probe heating phase
After switching on the COMTEC® 6000 analyser system by fitting in the fuse
F1 for the power supply, the COMTEC® logo appears on the display for a
short time. During this time, all parameters relevant for a fault-free functioning and start-up are checked automatically.
If during this check any system errors are found, the electronic unit will show
them in clear text (press then the soft key [status]). You will find a detailed
error and warning description in chapter 4.2 on page 57 and the following.
When the O2 sensor temperature is stable within ± 1.0 °C/0.18 °F (this
should be the case after approx. 20 to 60 minutes), O2 and COe measurement is released and the main window appears on the display. If the maximum heating-up time (default setting: 60 minutes) is exceeded or if such an
excess is predictable due to the heat-up speed, then the heating is turned off
and the error message "heating system don’t work" appears.
During the O2 sensor heating phase, all actual values can be called up in the
corresponding actual value menu window with the soft key [values]. You can
also enter the menu/cal. and the parameter menu by pressing the corresponding soft keys. Please note that some functions will not be available during the heating phase (e.g. calibrations). If you try to start menu items like a
calibration, you will get following information: “Function is being delayed until
probe is heating up”.
Note
After switching on the COMTEC® 6000 InSitu analyser
system, you have to wait 2 hours before any other activities are possible.
After completion of the heating phase, the main window is shown in the display (see Figure 18).

3.9.1
Altering a Parameter by the Example of the O2 Measuring Ranges
The electronic unit possess two freely adjustable O2 measuring ranges.
The measuring ranges of electronic unit can be determined freely. For
example one changes the “O2 Measuring Range 1” as follows:
To reach the menu option "O2 Measuring Range 1" please enter the parameter menu with [parameter] and select here the item “O2 sensor
params and meas.ranges”. Please press now the downward arrow until
the point "Meas.range 1 from" is reached. Then the point is to be accessed with [enter], and the system code has to be inputted and confirmed.
In the menu option "Meas.range 1 from" the initial value of the measuring
range can be indicated now.
Note
It should be noted that the initial value of the measuring range cannot be larger than the final value.
Likewise the final value cannot be selected smaller
than the initial value. Otherwise the electronic unit
does not permit the entered values.
After input of the initial value this value will be confirmed with [enter] and
the final value of the measuring range can be keyed in the menu option
"O2 meas. range 1 to". As soon as this value is also confirmed through
[enter], the electronic unit updates with the new measuring range.
Note
If you try to enter a value outside the permitted limits,
the corresponding limit value is selected.
3.9.2
Altering a Parameter by the Example of a Limit Alarm
Value
In this chapter the altering of a parameter will be explained using the example of value “limit 1 alarm”. For this purpose enter the parameter menu
with [parameter], select here the item “O2 sensor params and
meas.ranges” and select then with the downward arrow the item "Limit 1
alarm”. Then the point can be called up with [enter], and the system code
has to be inputted and confirmed.
Figure 26 Display: parameter input (example)
O2/COe COMTEC 6000 InSitu

Version 05.300.15
Page 38 of 80
In the window “Parameter Input – O2 System Params”, the parameter to
be altered is displayed in clear text with the current value. If special functions are assigned to this parameter (as like “min/max” as in this example), these are displayed, too.
The numeric value can be altered using the numeric keypad. To correct,
the cursor can be moved back with the [←] key. The sign can be selected
independently of the cursor position with the [±] key.
In this example, the secondary parameter “min/max” can be changed by
the corresponding soft keys.
Note
If you try to enter a value outside the permitted limits, the
corresponding limit value is selected.
The altered value has to be confirmed with the soft key [enter].
Note
When pressing the soft key [cancel], the altered value is
cancelled and the old value maintained.

3.9.3 O2 Correction ‘wet’ or ‘dry’ value
By design principle the COMTEC® 6000 measures the wet values. To
calculate and show the values as dry values in the display and also on
the mA-output, you have to enter the amount of moisture in the flue gas.
For this enter the parameter menu with pressing the soft key [parameter].
Select the item “O2 sensor params and meas.ranges” with [enter] and
then downwards to the item “Corr. flue gas” with [enter]. Now an information text will appear:
“Important information:
Moisture correction flue gas
When a fixed value is entered (average vol.% water vapour
content of the flue gas) the InSitu measured ‘wet’ value (real
value) will be converted into a ‘dry’ value. The ‘dry’ value is always higher than the ‘wet’ value!
A ‘dry’ value is designated by the ‘dry’ label at the top of the bar
graph of the measured value in the main measurement display.”
Accept this information with [continue]. Enter now the amount of moisture
in the flue gas and accept the entry with [enter].
You will now see the measured O2 value in the main window with the remark ‘dry’.

3.10.1 First Steps for Calibration
Important
Before you begin with the calibration make sure that the
conditions comply with the following points:
• You will need two test gas bottles for the system test and
calibration:
• Test gas 1 must contain 21% O2 in N2 and no combustibles like CO. Quality like synthetic air or instrument air
• Test gas 2 should contain 500 to 1000ppm CO and
2.1% O2 in N2.
Attention
Both test gases may require SO2 in ppm. Please contact
ENOTEC.
Are all pneumatic connections made correctly and gastight
to prevent the probe from ingress of ambient air? Please
make sure, that the tubing you use to connect the test gas
bottles to the electronic unit are adapted for this use (temperature-resistant, clean, undamaged).
Both test gas bottles have to be connected:
Connect the test gas 1 to test gas 1 connection and test gas 2 to test gas 2
connection. ( see chapter 2.6.2 )
The calibration starts from the main window.
Note
If the COMTEC® 6000 probe has only just heated up,
please wait at least 2 hours before you calibrate the O2
sensor and before commissioning the COe sensor.
Please wait at least 24 hours before you make the final
system test calibration.
Press the soft key [menu/cal.]. Before you enter this menu, you are asked
to put in the system code first.

3.10.3 O2 Output Settings
3.10.3.1 Freezing of Measured O2 Value
Start with the main window: [menu/cal.] “O2 … output settings” with [enter]
“Freezing of measured O2 value” with [enter] “Freezing of meas. O2
value … OFF” with [enter] and select the soft key [ON].
Under this menu item freezing of measuring O2 value memory can be
switched ON during calibration. With the freezing of measured O2 value on,
the last measured value before calibration is saved so that at the current
output the measuring value, which changes because of the calibration, has
no effect. The currently measured value is released again after an adjustable
delay, when the calibration is completed.
The default delay time is 3 minutes and can also be changed under this
menu item (“Return to flue gas in”) within the limits of 1 to 10 minutes.
3.10.3.2 O2 Measuring Range Switching
Start with the main window: [menu/cal.] “O2 … Output settings” with [enter] “O2 measuring range switching”.
Preloaded adjustment is “remote”. You can change the adjustment to “local”
by pressing []. Accept the change with [enter]. Return to the main window
with [cancel].
The electronic unit has two measuring ranges. The switching mode of the
ranges can be made manually from the instrument keypad, or by an external
remote 12-24 voltage input signal. This microprocessor parameter location is
used to determine which mode of range switching is required - local or remote.
The factory preset default in the electronic unit is "remote" range switching.
This means that in the case of an open digital input, the measuring range 1
is active. At the modus "local“, the measuring range can be changed in the
main menu with the soft key MR1/2 by hand.
Note
In case of errors and alarms, the soft key MR1/2 in the main
menu is occupied by status information. The status function
has the highest priority, therefore this means in case of errors
the measuring range cannot be changed manually (by hand).
3.10.3.3 Damping of O2 mA Output
Start with the main window: [menu/cal.] “O2 … output settings” with [enter]
“O2 mA-output damping” with [enter].
Preloaded adjustment is “00 sec”. Please enter the time in seconds by using
the numeric keypad and accept the entry with [enter]. By pressing [cancel]
you will come back to the main window.
O2/COe COMTEC 6000 InSitu

Version 05.300.15
Page 47 of 80
The mA-output can be damped if required. There are optional settings from 0
sec. (without damping) to a maximum of 55 sec. are available.
Damping is useful if the oxygen output signal of the electronic unit is spiky or
rough due to sudden process condition changes. A smooth or damped output can be obtained with the attenuation setting feature.
3.10.4 COe Output Settings
3.10.4.1 Freezing of measured COe Value
Start with the main window: [menu/cal.] “COe … output settings” with [enter] “Freezing of measured COe value” with [enter] “Freezing of
meas.COe value … OFF” with [enter] and select the soft key [ON].
Under this menu item a freezing of the measured COe value can be switched
ON during calibration. With the freezing of measuring COe value on, the last
measured value before calibration is saved so that at the current output the
measuring value, which changes because of the calibration, has no effect.
The currently measured value is released again after an adjustable delay,
when the calibration is completed. The default delay time is 20 minutes and
can also be changed under this menu item (“Memory hold time”) within the
limits of 1 to 180 minutes.
3.10.4.2 Damping of COe Measured Value
Start with the main window: [menu/cal.] “COe … output settings” with [enter] “COe measured value damping” with [enter].
Preloaded adjustment is “1 sec”. Please enter the time in seconds by using
the numeric keypad and accept the entry with [enter]. By pressing [return]
you will come back to the main window.
The measured value for COe can be damped if required. There are optional
settings from 1 sec. (without damping) to a maximum of 30 sec. are available.
Damping is useful if the measured value for COe is spiky or rough due to
sudden process condition changes. A smooth or damped value can be obtained with the attenuation setting feature.
3.10.5 Common … Settings
3.10.5.1 Change temperature unit °C/°F

3.10.5.2 Automatic calibration
Start with the main window: [menu/cal.] “Common … Settings” with [enter]
“Automatic calibration” [enter].
COMTEC® 6000 offers the opportunity of automatically performing a calibration procedure at regular intervals. This procedure however requires the version with a fully automatic pneumatic unit. All settings required for an automatic calibration can be made in this menu.
These are:
Automatic Calibration ON/OFF
As a standard, ACAL is off. In this item, ACAL can be activated.
Release mode
1. Time+External release
2. External release
3. Time only
Interval time (e.g. 90 days)
Indication of the calibration cycle time in days. At a value of 0 days the
calibration starts immediately upon release, this is important for a manual
remote calibration.
Remaining time xx days and xx hours
The remaining time until the next calibration is indicated under this item.
Note
For automatic calibration it is essential to connect a probe
with solenoid valve and to ensure that the test gas “air” is
always available and under pressure (instrument air version) or a pneumatic unit with pumps must be installed.
Important
If the calibration time interval in the parameter menu is
set to zero seconds for example - to make a remote calibration - it is very important that the release signal has a
maximum time of 60 seconds. A release signal of more
then 60 seconds could restart the calibration a second
time.
Please note that there is no "real time" clock in the electronic unit. It does not
know time of day, month or year. Only a clock-pulse generator is used for
automatic calibration purposes.
3.10.5.3 Relay output assignments
Start with the main window: [menu/cal.] “Common … Settings” with [enter]
“Relay output assignments” with [enter] “Output A assignment”.
By pressing [] you can change the relay assignment from “COe maintenance” to “O2 meas. range”. Accept the change with [enter]. By pressing
[cancel] you will come back to the main window.

4.3.4 O2 reads higher than expected, and COe reads lower
than expected

Possible reasons
Procedure
This may be due to a poor seal Tighten or replace the COe sensor coupling
of the COe sensor coupling
assembly.
located in the terminal box
housing. If the stainless steel
nut is not tight enough the Oring seal allows ambient air to
enter into the COe senor
mounting tube and that of
course influence the sensors
readings.
4.3.5 O2 Display remains at the End of the Measuring Range
or is higher than expected
Occurrence: At any time
Possible reasons
Leakages at the measuring
probe or at the O2 sensor
flange seal.
Solenoid valve does not close
because solid particles (metal
swarf or any other dust particles) are inside the solenoid
valve
O2/COe COMTEC 6000 InSitu
Analyser System
Procedure
Check all flanges and screw connections for
tightness. Exchange O2 sensor or replace
O2 sensor flange seal. In case of a leakage
in the area of the zirconium oxide O2 sensor, the O2 sensor must be exchanged.
Check the test gas tubing inside the probe
terminal box. Is there any dust visible in the
opaque (white) test gas tube inside the
probe terminal box? It is possible, that the
instrument air used as test air is contaminated by dust or condensed solids out of the
flue gas have settled there. It is also possible, that metal swarf (test gas tubing made
out of copper or stainless steel) settles inside the solenoid valve during system test /
calibration.
