KXB127 Mine Flameproof and Intrinsic Safety Audible and Visual Alarm
an instruction manual
1、 Overview
KXB127 mine flameproof and intrinsically safe audible and visual alarm is used in the places where there is danger of gas and coal dust in the coal mine, such as the rail deviation, air door, boarding and alighting plant, etc. When the locomotive runs to these places that need to be alarmed, such as: turn, turnout, start the language alarm: "When the locomotive passes the turn, please pay attention to pedestrians". After the air door is opened, prompt "Pedestrians pass, close the air door" and "Shoot ahead, evacuate people immediately, no entry" in time. When it is used for the inclined shaft winch, the language prompt "Driving, No Pedestrian" is displayed; When it is used for vertical shaft, the language prompts "signal has been sent, no tank entry". This product is mine flameproof and intrinsically safe equipment, of which the sensor, loudspeaker and LED signal display circuit are intrinsically safe circuits. Equipped with explosion-proof solenoid valve, it can realize automatic spraying and dust reduction through the locomotive.
2、 Working environment
1. Atmospheric pressure: 86~106kPa, altitude not more than 2000M
2. Ambient humidity: not much more than 95% (+25 ℃)
3. Ambient temperature: - 5 ℃~+40 ℃
4. Where there is no significant vibration and impact
5. There are mixtures underground in the coal mine, but there are no corrosive gases that can damage the insulation and the occasions that can prevent sewage or other liquids from being immersed
6. Pollution level:
7. Installation category: Class III
3、 Product model and meaning
KX B 127
working voltage
Audible and visual alarm
Mining signal equipment
4、 Main technical parameters and functions
1. Explosion proof type: mine flameproof and intrinsically safe
2. Explosion proof sign: Exd [ib] I (150 ℃)
3. Power supply voltage: 127V
4. Large working current: 0.2A
5. High open circuit voltage at intrinsically safe output terminal: 12V; High current: ≤ 1300mA
6. Sound level shall not be less than 85dB
7. Light display: red and green, visible within 20 meters in the dark.
8. Main functions: when there is no trigger signal (high level) between the terminal "sensor" of the alarm, the alarm will display a green safety pass sign that is always on; When there is a trigger signal (low level) between the "sensors" at the terminal, the locomotive triggers the sensor, turns off green and displays the red "Driving, No Pedestrian" luminous font, and at the same time continuously reports the voice prompt sound of "The locomotive is passing the curve, please pay attention to pedestrians"; The warning delay time of voice and luminous font is 15 seconds ± 5 seconds When the delay time is up, the red words of the alarm will go out, and the green light will return to normal to prompt the luminous sign, and the voice will stop.
When it is used for air door or other places requiring alarm, as long as the sensor gives<0
