Test And Calibration - Tecno Control TS282K User Manual

IST-2282.KM01.01(Rev.1)
Periodical testing: we advise to carry out working tests every 12 months. Operation Check, Zero Adjust, Calibration
Check and Calibration with Gas/Air mixture as explained on page 4 chapter Tests and Calibration.
Note: the detector is not able to detect gas leaks occurring outside the room where it is installed, neither inside walls
nor under the floor.
Important: The catalytic sensor operates only in presence of Oxygen. Do not use pure gases or a lighter directly on
the sensor since they could damage it irremediably.
Warning: some substances cause a permanent reduction in sensitivity. Avoid contacts of the sensor with vapours of
Silicone compounds, Tetra-ethyl Lead (petrol antiknock additive) and Phosphate esters, since they can reduce
irremediably its sensitivity. Some substances produce a temporary loss of sensitivity. This "inhibitors" include
Hydrogen sulphides, Chlorine, Chlorinated hydrocarbons and halogenated compounds. The sensitivity is recovered
after a short period of running in clear air.

TEST and CALIBRATION

PAY ATTENTION: This procedure has to be made with extreme attention and by authorized and trained
people; because starting this procedure it will increase mA Output causing the activation of connected alarm
devices to the gas Central Unit.
Operation Check, Zero Adjust, Calibration Check and Calibration: are different code protected functions. To
access these functions 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 Bottles (for Calibration Check and Calibration) please, only using a mixture:
Catalytic sensors cannot work in oxygen deficiency. It is possible to use either the disposable one litre cylinders
with adjust valve or the high pressure ones with reduction gear. It is also necessary to use the calibration kit
Tecnocontrol model TC011 (for non-corrosive gases) or TC014 (Stainless steel).
"INSTRUMENT OPERATION CHECK" (Check Code: F2, F2, F1, F1): this function allows to effect a functional
test of the equipment. After having put the system in safety and inserted the "Code Test", all Led are switched off.
Then they will switch on in sequence, the Led, from the yellow up to the red. At the end all the LED will remain lighted
for around 5 seconds, then the instrument returns at the conditions of normal operation. It is advisable to perform this
operation every 6-12 months according to the use.
Note: this function is not working if the red Led is already turned on
"ZERO ADJUST" (Zero Code: F2, F1, F1, F2): this function is to adjust the Zero sensor and can be done in clean
air only (environment without the presence of gas or other pollutants). Immediately after having inserted the "Zero
Code", as a confirmation of the operation carried out there will be 1 flash of the Red Led and the output will become
4,0mA. We suggest performing this operation
the change of the cartridge and every 6-12 months based on the environmental conditions.
Note: This function is not working if mA output is more than 12mA (10% LEL) and/or red Led is already been
switched on. In this case, it will be necessary to recalibrate the unit and/or replacing the "Cartridge"
"CALIBRATION" (Calibration Code: F2, F2, F2, F1, F2, F1): this function allows completely recalibrate the sensor.
Warning: to guarantee that no errors of elaboration happen, the rare possibility exists that during the Calibration the
yellow LED switch off every 8 seconds, in this case interrupt the procedure, switch off and witch on the instrument
and repeat the Calibration. If condition persists it will be necessary to send the detector to the supplier for the
reparation.
Important note: During Calibration routine the mA output indicates 0mA.
The "Calibration" can be done in clean air only (environment without the presence of flammable or other polluting
gas). With the keys perform the "Calibration Code ". Wait until the Yellow and Green Led switch on fix and the red
Led starts to flash. Insert the TC011 over the sensor holder, adjust the sample gas bottle valve (0.88%v/v methane
in air), as the flow meter indicates around 0.3 l/mins
switch on (and while it's SWITCHED ON), press the key F2 on the instrument and hold it pressed until the Red Led
is switched off for at least 2 seconds (if the Red Led continue to flash, repeat the operation). Then, close the gas
cylinder and remove TC011. At this point we can have two possibilities:
Yellow and Green Led illuminates: the calibration routine has correctly been performed. Wait 8 seconds, until the
instrument automatically restores the normal working conditions. (see "Operational Description > Preheating")
Yellow LED illuminates: the routine has failed. In this case, wait 8 seconds, until the instrument automatically repeat
Preheating, then repeat the "Calibration" routine without inserting again the code. If condition still persists after the
replacement of the cartridge, it will be necessary to send the detector back to the manufacturer for reparation.
"CALIBRATION CHECK" (Cal Check Code: F2, F1, F2, F1): this operation allow to effect a real functional test of
the equipment with gas after the "Calibration" routine, or after the installation. The "Calibration Check" routine should
be done during the periodic maintenances because this is the only method to verify the instrument real functioning.
