I.2. PACKAGE CONTROL
Pull out the analyser from the original package and examine it in order to detect any kind of
external damage that can occur during shipment. In case of damage, missing part or suspect
situation, please contact TECORA company or its agent.
I.3. INSTALLATION AND USE CONDITIONS
Affect the analyser to clean and well defined location. It will allow to protect the unit from any
damage and will improve reliability.
The analyser should be installed on a site where it will be protected from rain (we can supply
water proof cabinet in option for outside mounting). If temperature is supposed to decrease
under 0°C, an heating system is necessary (don’t hesitate to contact us).
Foresee 100 mm space behind the analyser in order to be able to realise gas and electrical
connections without any problem.
If ambient temperature fluctuates a lot, it will be necessary to recalibrate the instrument more
often than foreseen.
Avoid to install the unit in an area where there are strong vibrations or strong electromagnetic
fields.
All electrical wiring will be done with shielded cable, screen connected to the earth at analyser
side.

II. DESCRIPTION PART GAZ
II.1 INTRODUCTION
The gas analyser model CATARC10 MP-R has been designed for simple and accurate
measurements on dry and clean gas. The instrument uses thermal conductivity principle for gas
content measurements in binary blending or equivalent of binary blending (example : air). It had
also a catharometric detector with microthermistor designed and built by ARELCO for a good
stability.
II.2 MEASUREMENT PRINCIPLE
The gas analyser model CATARC10 MP-R could be used in a blending where the component
to measure has got a far different thermal conductivity of other gas of the blending.
As you know, thermal conductivity is not a specific data of a gas. (several gases can have the
same thermal conductivity). Actually, the instrument measures the difference between two
thermal conductivities. So it is absolutely necessary to check that both gas of the blending have
different thermal conductivities in order that the unit provides the best performances it can.
The main element of the analyser consists in the detection cell. It includes two thermistors
mounted in opposition in a Wheastone bridge.
one thermistor is installed in the ‘sample gas’ circuit
the other one is installed in the ‘reference gas’ circuit
The reference gas is usually the main gas of the blending.
The content of gas to measure is given by the difference of balance between both thermistors.
So main operations to perform are :
balance of the bridge (zero setting)
calibration of the bridge with calibration gas (span setting)

THERMAL CONDUCTIVITY DATA
The range of the instrument is depending on the application. It has to be check with our
specialist engineers.
We give just under the thermal conductivities of main gases.
The unit is : cal/(sec) (cm²) (°C/cm) 10-6. In order to convert this value in Btu/(hr) (ft²) (°F:/:ft) X
10-6, multiply per 241.909.

II.3 GAS CIRCUIT
The analyser has an 1/8” NPT female inlet and oulet. The flow must be equal from 0.2 to 0.8
L/min. The recommended flow is 0.5 L/min. The flowmeter allows a regulation of the flow in the
sensor at about 100 cc/min.
The gas pressure must be contained between 0.9 and 1.1 bar (absolute). In case of a higher
pressure, use a pressure regulator at the inlet of the instrument. In case of a lower pressure,
use a pump. It must be placed above the instrument. Like that, the gas will be pushed in the
analyser (cf. scheme).

III. ELECTRONIC DESCRIPTION
III.1. INTRODUCTION
The analyer integrates a microprocessor electronic designed to answer at the
market’s inquiries.
The tactile screen allows to see quickly the totality of the essential parameters : gas
content, barometric pressure (option), temperature regulation, alarms status…
The analyer incorporate a internal function for data memorization (350 data)
extendable by a SRAM card (option) which assures on top of that a total control of
the analyser (alarm threshold, error message, calibration, modification of the
configuration…)
A parallel output allows to connect the device to a printer (output on listing). The
RS232 output permits to connect a PC for the acquisition of the measurements
under “terminal” in WINDOWS.
The calibration of the analyser can be done with manual or automatic sequence,
according to user configurable protocol.
The alarms and the other logical signal are avalaible on SUB D connectors (5V/100
mA maximum). A separated interface box allows to make use of these informations
with SPDT contacts or direct supplying of these components.
III.1.1. PASSWORD
The modification of the parameters seen in the menu is protected with a password.
Protection A: press during 6 seconds on indication . (dot) on the right of the zero.
The indication –on the left of the zero will be chenged on <-. The protection is
inactive in this page.
Protection B: the code is 4875.

III.1.2. TOUCH SENSITIVE DISPLAY
The user has to press on the good item to select it. It is recommended not to use any
pen or hard point for this operation. The touch sensitive display could be damaged.
III.1.3. Principal display
On the power on, the analyser displays :
-the program version
-the device model
-the time
-the TECORA phone number
-the TECORA fax number
the device switchs over to the principal screen of data « routine screen »
The « routine screen » gives indications about:
-the measurement
-alarm status
-operating phase of the device in coherence with its general parameters (made
in our manufactory for some tasks, or set by the user for available functions in
several menu pages and accessible by “MENU” touch in the bottom right
corner of the screen)
It contains :
-the time
-measured gas content
-threshold alarm and flow
-informations in relation with
sensor thermostatisation
calibration

On the power on, the device has to stabilized the sensor temperature before doing
optimal measurements.
It runs with a heating phase, indicated on the screen by a message « heating » on
the top of the screen.
In a first time, the difference of temperature between the real temperature of the
sensor and the instruction ( fixed in our manufactory at +45°C ) is big.
The message “heating” is activated. The temperature indication of the sensor is
displayed on the range from 0 to +60°C.
When the temperature is near +45°C; the temperature of the sensor displays a
window which indicates the temperature difference in a band of temperature about
+/- 5%.
From this moment, the heating line is replaced by the message “SENSOR READY IN
… MINUTES” with the count of the last time.
This temporisation allows to assure a good homogeneity of temperature at the level
of the sensor for better measurements.
At the end of the count, the messages concerning the startup phase disappear.
The device is on analysis routine and general function, in conformity with the last
setting realized.
Nota: in case of breaf shutdown (< 1’), the analyser restart if the sensor temperature
desn’t drift. In the opposite, the routine is reactivated ( When it restart, the screen
displays a page of several characters during its initialization phase.)
IV. SETTINGS
From this routine screen, enter to the first page of the menu by the key “MENU”on
the bottom right.

On the analyser, the state 0 fits to the closed contact and the state 1 for the opened
contact for the inputs. For the outputs, the state 1 fits to the logical state 5V and 0 to
the logical level 0V.
It is possible to run the alarm outputs of the analyser in positive or passive security.
This setting is applied to the alarm relays A1 and A2 and to the relays connected
with the state CALIBRATION, ANALYSER DEFAULT, and MEASUREMENTS NOT
VALID.
In order to modify the running mode, report to the section CHOICE OF THE
RUNNING MODE OF THE SPDT RELAYS.
The positive security is called NOR. The passive security is called INV.
The separated interface box is available to directly work on the outputs.

Settings of the outputs TOR
CALIBRATION IN PROGRESS ( from 1 to 9 of SUB D) “ETAL”.
This output is activated when the calibration phasis. It is active during all the sample
period, increased of time of Frozen Out.
On the other hand, if there is a CAL ABORTED during automatic calibration, It
becomes flashing at 1 Hz. This situation is delocked by a calibration realized with
success, In preference in manual,.for the well understanding of the validity of it and
understand the cause of the last abort of calibration.
NOT VALID MEASUREMENT (3 and 11 of SUB D) “NVM”
This output is activated as soon as the user isn’t in the routine screen, or the
analyser is in preheating phasis, or the user is in the phasis FROZEN OUT (see
previous section). This information allows to emit caution on the quality of the signals
in progress available on ANALOGIC outputs, on screen and on PC.
