Conventional Gas Sensor SG544
V. 3
The SG544is born from the elegance and prestige that has always distinguished BEINAT S.r.l. and from the
home fitness concept.
The probe is a Catalytic gas detection unit with IP44 protectionthat, together with one of BEINAT’s industrial
type Control Units, detects the presence of esplosive gas such as Methane, LPG.
Thesensorprovidesasignalofalarmtothecontrolunittowhichitisconnectedwithasensitivityofintervention
calibrated within 20% of the LEL.
The degree of protection that is provided allows the useeven in critical conditions of moisture, dusty
environments and where the norms require, making it ideal for its use in industrial environments.
The probe has a linear output 0 to 20% LEL, working with the standard 4 to 20 mA.

CHECK the integrity of the unit after having removed it from the box.
Check that the data written on the box correspond to the type of gas used.
When doing the electrical connections, follow the drawing closely.
Any use of the detector for purposes other than the intended one is considered
improper,andasaresultofwhichBEINATS.r.l.thereforedisclaimsanyresponsibility
for possible damages caused to people, animals or objects.
TERMS and EXPECTATIONS:TheinstallationoftheSG544Probe,its ordinary and
extraordinary maintenance, every six months, and its out of service removal at the
end of the functional life guaranteed by the manufacturer, must be carried out by authorized or specialized
personnel.
Do not allow it to become wet.
The control unit can be seriously damaged as it is not waterproof either when immersed in water or exposed to high
levels of humidity.
Do not drop it.
Heavy knocks or falls during transportation or installation can damage the appliance.
Avoidabrupttemperaturefluctuations.
Sudden temperature variations can cause condensation and the control unit could work poorly.
Cleaning
Never clean the device with chemical products. If necessary, wash with a moist cloth.

WARNING!
The CATALITIC sensor has a life span of 5 to 6 years in clean air.
The working temperature of the probe recommended is from -10 ° C to + 50 ° C.
Every puffy snapshot of gas over 100% of L.I.E. Takes months off the sensor.
Each immediate puff of gas that exceeds 100% of L.E.L. takes away months of life from the sensor.
The detector must be tested by simulating the presence of gas by issuing it from a pre-calibrated testing aerosol.
Important:
The test of operation and eventually offset cancellation must be performed at least once a year, by a qualified
technician.

MAINTENANCE
The user periodically (every 6 months) must perform a check of the operation of the control unit by spraying
a suitable test gas at the base of the probes connected until the alarm condition is reached.
• At least once a year make a more accurate check by a specialist technician.
• Disabling the detector must be carried out by qualified personnel.

The position of the probe is a crucial factor for a gas detection unit correct functioning.
Inordertoobtainthemaximumresultsfromanapplianceandminimizetheprobabilitiesoffalsealarms,we recommend
to follow this diagram and to keep in mind the following general rules.
The remote probe must be located at different heights, according to the type of gas.
These heights are:
- 30 cm from the lowest point of the floor in order to detect heavy gases (L.P.G. etc.)
- 30 cm from the highest point of the ceiling in order to detect light gases (Methane, etc.)
The probe should not be placed near the appliances to be controlled (boilers, burners, industrial kitchens, etc.) but
on the opposite wall.
The probe should not be affected by smoke, vapour, etc. as they could distort their measurement. It must be placed
away from sources of heat, suction fans, ventilation fans.

Gas Imput Test
If the device does not start up.
Check that the 12/24VDC mains power is correctly connected, and that positive and negative polarity has not
been inverted.
If the Fault LED lights up.
If the fault signal reaches the control unit connected to the probe.
Check that the cables are connected according to the drawing, and that the wire isolation sheath has not been
pinched.
Check the voltage at the terminals 1-2. It must be higher than 11VDC and lesser than 25Vdc.
Check the voltage at the terminals 2-3. It must be from a minimum of 1 VDC to a maximum of 1.6 VDC
If other problems arise, a specialised and/or authorised technician and/or the Distributor of BEINAT S.r.l. should
be contacted directly.
The installation of the SG544 probe, its ordinary and
extraordinary maintenance, and its out of service removal at
the end of the functional life guaranteed by the manufacturer,
must be carried out by authorized or specialized personnel.
The general test should be performed by issuing gas from a pre-
calibrated aerosol.
According to the EN 60079-10 Norm, this functioning test
should be performed at least once a year.

WARNING! Actions to be taken in case of alarm
WARNING! Actions to betaken in case of alarm
Gas
1) Put out all free flames.
2) Close the main gas tap or the LPG cylinder tap.
3) Do not turn any lights on or off; do not turn on any electrical device or appliance.
4) Open windows and doors in order to increase ventilation.
If the alarm stops, its cause must be found and the relevant consequent measures taken.
If the alarm continues and the cause of gas presence cannot be found or removed, abandon the building and call
the emergency services when outside (fire department, distributors, etc.)
IMPORTANT: The operation test should not be carried out with the gas tap as this does not guarantee a sufficient
concentration to activate the general alarm.
Warning!!
If you have the following symptoms: vomiting, sleepiness, or else, go to the closest first aid station
and inform the operators that you could have been poisoned by Carbon Monoxide, or by an excess
or deficiency of oxygen
