only a warning, the detector continues to operate normally, but then is necessary replace and / or send the detector
back to the supplier to replace the "Sensor" with a new one.
Periodical testing: depending on the use, we advise to carry out working tests every 6÷12 months. As explained in
chapter "Tests".
Note:
the detector is not able to detect gas leaks occurring outside the room where it is installed, neither inside
walls or under the floor.
WARNING: Consider that in polluted environments or with temperature, pressure or Humidity more than the de-
clared limits, the useful life of the sensor can be reduced.
TESTS
PAY ATTENTION: following tasks should be performed with attention and by competent and trained per-
sonnel; because starting this procedure it will cause the activation of connected alarm devices.
Operation Check and Calibration check with Gas: are different code protected functions. To access these func-
tions is necessary to insert the relevant "Code" through the keys F1 and F2. To have the key pressure recognized,
hold pressing it for around a second (until the Green LED doesn't switch off for a moment). Then the next key can be pressed.
In case of error all it takes is waiting around 10 seconds and the sequence is automatically erased.
Calibration Kit, Sample Gas Cylinders
Sample Gas Cylinder for SPAN Calibration
1% Volume Carbon dioxide (CO
Sample Gas Cylinder for ZERO Calibration
Pure Zero Air (less than 5 ppm CO
You can use disposable cylinder, complete with adjust valve. It is also necessary to use the calibration kit
Tecnocontrol model TC012.
"INSTRUMENT OPERATION CHECK" (Check Code: F2, F2, F1, F1): this function allows to effect a functional test
of the equipment. After having inserted the " Check Code ", all LED are switched off. Then LED will switch on in se-
quence, from the yellow up to the red. At the end all the LED will remain lighted for around 5 seconds, and then the
detector returns at the conditions of normal operation. It is advisable to perform this operation every 12 months ac-
cording to the use. Note
switched on.
"CALIBRATION CHECK WITH GAS" ( no Code required ): using the gas mixture indicated above, this function is
used to control the correct response to the gas and can be made be made after the installation. But it should be
done during the periodic maintenances, to verify the effective functioning of the detector.
NOTE: please use, the gas mixture as indicated above. Normally it is sufficient to perform the Calibration check with
gas , ( 1%Volume CO
Cylinder in nitrogen ) but you can also carry out Checking Zero ( Pure Zero Air Cylinder ).

contact our customer service. Then, close the gas bottle; move away the TC011. Then, the mA output will slowly
decrease up to 4mA.
Example if you have to verify a TS210 IC2 using a cylinder with Pure Zero Air, the mA output will be 4.0 mA (cor-
responding about to 40 mV measured on "TESTmV"). Then using a cylinder with 1%volume (= 10000 ppm) CO
nitrogen, the mA output will be approximately 12.0 mA (±0.56mA) (corresponding value from 1145 to 126mV meas-
ured on " TESTmV").
FR DESCRIPTION
Les TS210 IC2 sont des sondes de détection de CO
sor), utilisées dans les systèmes centralisés de détection de gaz destinés pour la première aux alarmes pour labo-
ratoires, industries alimentaires, caves vitivinicoles et brasseries et pour la seconde aux contrôles de la quantité
d'anhydride carbonique présente dans les serres. La sonde est constituée d'un boîtier contenant le circuit électro-
nique ainsi que les borniers de raccordement. Le capteur, est à l'intérieur du boîtier et est en contact avec l'envi-
ronnement par une grille en acier, placé sur le couvercle du boîtier.
Les TS210IC2, sont sondes à transmetteur sur 3 fils avec un signal de sortie (S) 4÷20mA linéaire, cette sortie se
raccorde à une centrale de détection de gaz
tinées aux opérations de vérification, utilisables à l'aide d'un code et de 3 leds.

NOTES SUR LES DIFFERENTS MODELES
Le TS220 IC2 est calibré avec fond d'échelle à 2%vol soit 20000ppm de CO
L'anhydride carbonique (synonyme: bioxyde de carbone), est un gaz inodore et incolore, plus lourd que l'air puisque sa
densité relative à celui-ci est 1,5 a par conséquent, tendance à s'accumuler en partie basse des ambiances en gé-
nérant une dangereuse carence en oxygène. Sa TWA (Time-Weighted Average) est de 5000ppm = 0,5%vol et sa
STEL è 15000ppm = 1,5%Vol (Short Term Exposure Limit).
