Ver:HWWM160617CG
Safety information
1. Before using the device, please first carefully read and follow the
following information to operate the device:
2. Please don't use the defective detector. Before using, please check if
there is crack or spare part missing. If yes, please contact the seller.
3. In order to keep the accuracy, please calibrate it once before the first
time using.
4. Working voltage of the detector is DC18V to DC30V and recommended
voltage is DC24V. The voltage exceeding DC30V will damage the
detector.
5. Before using, please make sure the housing is fixed.
6. There should be no speedy gas flow on the installation place. Otherwise,
it will influence the detection result.
7. Please don't expose the device to the gas which concentration is
exceeding the range. Otherwise, it will influence the accuracy and
shorten the sensor life.
8. Please don't paint the sensor parts or detector.
9. Only sensor spare parts which are specified for BS03 are allowed to be
used.
10. It's suggested calibrate the sensor once every 6 months.
11. In order to avoid damage human beings, please operate it when power
off. Before opening the cover, make sure there is no mixture gas of
combustible gas and air. Otherwise, it will possibly cause fire or
explosion.
12. Please avoid water or dust to come into the housing.
13. Please don't expose the device to the environment which has electric
shock, strong magnetic field or serious continuous mechanic shocking.
14. When no using, please take out the battery from the remote controller.
15. Installation must abide by the national and local regulations.
16. It's forbidden to disassembly, adjust or repair the device without
permission.
17. All the operation inside the device must be carried by professional
persons.

1. Brief introduction
BS03 fixed gas detector, adopting high-quality catalytic gas sensor and
SMD arts and crafts, has advantages of good reproducibility, disturbing-proof
against temperature and humidity, long life-span and easy operation.
The signal output of BS03 is standard 4-20mA. It is widely used in
refineries, chemical plant, LPG station, gas boiler, and Spray-Paints etc where
gas leakage easily.

4. Installation
4.1 Installation position
1) For petrol gas, oil gas and alcohol gas etc. which is heavier than the air,
the position is 0.3m-0.6m higher than the ground.
2) For natural gas, CH4 etc which is lighter than the air, the position is
0.5m-2m higher than the gas source. Gas density more than
0.97kg/CBM, then it's heavier. Gas density less than 0.97kg/CBM, then
it's lighter.
3) The position should be far away from shocking, shattering, strong
electromagnetic interference. Around the position, there should be at
least 0.3m empty place.
4) The position should be within 1m around the possible gas leakage area,
such as valve, pipe connection point, gas outlet place. Please try to
install it nearer to the above places, but avoid influencing the working of
the other equipment. Please avoid the environment of high temperature
and humidity. Also please keep it from water swashing, oil and
mechanical damage. Please also consider the convenience of
maintenance and calibration.
5) For large scale detection, we suggest install 1pc every 10-12 square
meters, so as to get the best detection result.

4.3 Installation methods
Note: Fix the detector with sensor head downwards!
According to the installation place, you can fix the detector onto the wall or to
the gas pipes. Please follow the details as below:
Method 1(thread butted type fixing method): If there are transverse
or vertical siphon with G3/4 Screw thread in installed places, please
connect the two terminals of the detector to the gas pipes. Then connect
and screw down the pipe screw thread nut and fix it tightly.

Method 2: If the user needs to install the detector onto the wall, please
choose an appropriate place on the wall according to the detector
dimensions. Then fix the detector by using 3 pieces of M6×70 bulge
bolts in the corresponding installed holes.

Method 3: If there is 1" to 2″(diameter) pipe, the user can use 2 U-type
bolts to fix the hanging plate on the pipe, and then fix the detector onto
the plate. Or, the user can first fix the detector onto the plate and then fix
the plate on the pipe.
5. Wire connection
Note: Electricity power must be cut off before wire connection.
Wire connecting steps:
1) Screw down the cover in counter-clockwise way. Then use a cross-type
screw to screw down the 3 bolts and take off the display PCB.
2) Screw down the pipe connector in counter-clockwise way. Take out the
explosion-proof pad. In turns, put 3-line wire to the internal of the
enclosure through the pipe connector, compaction circle, air-proof
closing plug and the wire connection hole. According to the
explosion-proof requirement, please don't take out the explosion-proof
closing plug from the unused wire connection holes. Please don't throw
away any part inside the enclosure or the PCB.
3) All the wires should be connected to the terminals. The terminal
instruction is as follows:
