KXT102 signal switch -KXT102 communication signaling devices -KXT102-127V-36V

KXT102 communication signal device (hereinafter referred to as signaling devices) KXT102 signal switch -KXT102 communication signaling devices -KXT102-127V-36V I developed for the mine explosion-proof and intrinsically safe, suitable for underground gas environment having a belt transport and winches liaison with the transport of the signal. It has the following features: a transmission signal: Press flameproof signal button this station can emit sound and light signals (RBI) to each station this station is connected machine. b receiving signal: Even machine each station can receive any of a sound and light signals emitted (RBI). c single function intercom: Under this signal does not change the existing coal mine explosion signal wiring and power supply to the case, connecting the station to achieve power line carrier intercom function through the power line without additional cabling. 1.2 Composition and representational model KX T 102 registration numbers Mine signal device signal device 1.3. Proof type explosion-proof type: Mine explosion-proof and intrinsically safe, explosion-proof mark: Exd [ib] Ⅰ 2 · KXT102 signal switch -KXT102 communication signaling devices Dimensions and Weight Dimensions: 128mm × 186mm × 320mm Weight: 9.5 kg 3 · KXT102 signal switch -KXT102 communication signal Technical Data 3.1 Operating voltage:. AC 127V 3.2 operating current:. ≤0.2A AC 3.3 signal distance calls: 2000 m Online 3.4 Number of units: 10 units (minimum 2) 4 · KXT102 signal switch -KXT102 communication signal means environmental conditions signaling device under the following conditions a reliable operation temperature: -5 ℃ ~ + 40 ℃; b humidity:.. ≤95%; c Atmospheric pressure: 80kPa ~ 106kPa; d. Environmental noise: ≤75dB e an explosive mixture, but no damage to insulation corrosive gas applications. 5 · KXT102 signal switch -KXT102 communication signal means structural features 5.1. The product is light weight, set the old RBI button, explosion-proof lights, explosion proof bells, three wiring of several functions in one. The original proof lamp from the current high-brightness light-emitting diodes in place, visually striking and unique; original bell from the current place of waterproof speakers, your voice loud, transmission distance. RBI button instead of by the local RBI button. The signaling device explosion chamber has a separate terminal compartment, external stay four outlet ports, without followed tees. Carrier calls the original function on the basis of the same, greatly reducing the labor intensity of workers underground operations. Simple overall structure is reasonable. 5.2. The signal devices and other similar products have the following three advantages: (1) the product wiring is simple, easy to maintain; does not change the original wiring; without additional cabling. (2) The product uses FM power communications carrier, anti-interference ability, transmission distance and clear. (3) This product uses a modular structure, epoxy potting, anti-moisture, anti-vibration, easy maintenance. 6 · KXT102 signal switch -KXT102 communication signal device works sent 6.1 sound and light signaling functions (RBI): power connection A, B terminal, C intermediate terminals. Press the "dot" button "DDAN" (red) for all online each station C terminal and B terminal constitutes the power supply circuit, the module starts ringing and ringing LED1, LED2 light. Ringing signal by C17, C18 to the speaker amplifier IC2 promote YSQ ringing. Achieve sound and light signals sent liaison function. 6.2 functions by saying: Language carrier signal emitted by the other four high-voltage isolation capacitor VC1 ~ VC4 and coupling coil L1, L2 to the "detection" module, after detecting the resulting sound signal to the amplifier through C18 Manifold IC2 push speaker sound. 6.3 speaker function by pressing the "talk" button TXAN (green), power amplifier IC3 has power, the sound through the microphone MIC into IC3 enlarge. The audio signal is amplified, synthesized by "carrier module" carrier signal through the coil L1 and the coil L2 and the capacitive coupling to the four high-voltage power supply line A, a B, is sent to each of the other units, the speaker function. 7. Installation and use 7.1 installation:. A Open the front explosion chamber cover, terminals A and B power supply is 127V, C terminal connected to the intermediate output line. Grounding wire to ground. b. When the signal means access to power lid, check with no missing after the explosion before transmission to use. (Cables of 1.5mm2 × 4 core rubber cable). c. If a wiring error, the RBI will issue a noise or sound, as long as the swap A, B wiring can be. 7.2:. A transmission signal (RBI): Press the "dot" button (red) this station and line each station audible and visual signals. b call: Press the "Call" button (green), speaking into the microphone, all other stations will hear each other's speech. (By then do not press the call button). 8. Precautions and maintenance a. Power and the rated voltage to be consistent nameplate. according to the schematic wiring b. When must "first off lid" repair, replace modules, speakers and microphones and other consumables. c. Line bell must closure when not in use. d. if damaged can be replaced module. e. must protect the surface explosion overhaul, surface explosion if the damage can not be reused. . Warnings * Please read the instruction manual before using the device connection * only specified and used in the specification, subject to proof test the connection with other devices. * Maintenance should prevent sparks: pay attention to not damage the surface explosion, fastening the terminal box cover plate, shall not be lost ring introduction means, appropriately tighten the compression nut. * Should not be changed intrinsically safe circuits and associated circuit specifications, models and components of electrical parameters overhaul. 9. Failure Cause and treatment: ⑴ when no RBI ringtones, first check button "DDAN" is damaged, no damage is possible if the speaker bad, such as damage to the phenomenon described above have no power board bad need of replacement. ⑵ no RBI normal call, first check the call micro-switch and microphone for damage, if normal communication board can adjust adjustable potentiometer until the call is normal. No effect is illustrated above overhaul communications board is bad need of replacement. ⑶ as neither RBI and no ringing call, may fuse or transformer damage, if the transformer fuse and who are normal, the power board bad need of replacement.
