KXJ127 mine explosion-proof and intrinsically safe level controller circuit using electrode sensor, electric ..

KXJ127 mine explosion-proof and intrinsically safe level controller circuit sensing using electrodes, inductive signal strength, liquid level adjusted water level of the product KXJ127 mine explosion-proof and intrinsically safe level controller is the latest research and development The new products, lower Inoue for the mine and the need for liquid level control of the premises. Stable performance, the line from the tip processor Lpc921F do live a short time, and a working status corresponding indicator, manually force control, exhaust / water two digital switches, function selection and convenient, widely used, easy installation and so on. Suitable for occasions with methane and coal dust in the gas mixture. Second KXJ127 mine explosion-proof and intrinsically safe level controller model named 1, Model naming KX J 127 voltage flameproof and intrinsically safe control 2, explosion-proof form and sign the form: mine explosion-proof and intrinsically safe Explosion-proof mark as: Exd [ib] I three, KXJ127 mine explosion-proof and intrinsically safe level controller environment 1. temperature 0 ~ + 40 ℃; 2. Humidity: less than 95%; 3 atm 80 ~ 106kPa; 4. no significant vibration and shock of the occasion; 5. underground mine without damage to the insulation of the corrosive gas; 6. for hazardous locations with a mixture of methane and coal dust explosion Fourth, the technical parameters Rated voltage: AC127V; Current Rating: 100mA; five, KXJ127 mine explosion-proof and intrinsically safe level controller works 5.1 drain state, then the corresponding AC 127V power supply, after the red light, green light, yellow light flash in succession if the level is higher than the water level electrode position the red light is off, the yellow light flashing green light, drainage work. Drainage has to start the motor delay, duration 5-10 seconds adjustable, avoid the level fluctuates, the motor frequent starting and damage. 5.2 Water state, connected to AC 127V power supply accordingly after the red light, green light, yellow light flash in succession if the level is below the lower level electrodes positioned as red light is off, the green light flashes, the yellow light, drainage work. Water feature is also provided with a starter motor delay, duration 5-10 seconds adjustable 5.3 sensing circuit using electrodes, inductive signal strength, so that the liquid level and low water level control is more accurate, and easy to install, liquid level adjusted. 5.4 in need of emergency discharge / hour water supply automatic circuit failure or, can be manually forced control exhaust / water continued to work at the level is too high or too low downtime, because of a protective circuit, avoid liquid overflow or the motor idling damage. 5.5 circuit board features two digital switch, labeled with drainage, water supply, manual, power supply, caps, floors, export, to other functions, user-friendly installation feature selection. 5.6 grounding device, dielectric strength greater than 50MΩ, contact current 5A six, KXJ127 mine explosion-proof and intrinsically safe level controllers 1. Install the 127V power supply connected to the motherboard's "0V" and "127V" terminal; 2. External motor control node "K1-1", "K1-2"; 3. external manual button control node "Manual -1", "Manual 2"; 4. external level electrodes were connected to "ground", "down water "," upper level ", when the electrodes are placed may be" under water "placed in the" land "and relatively close to the top position (typically 20cm up and down), but not in direct contact," on stage "to the actual needs of the user place. 5. The user may need to be adjusted according to the actual "Water" and "drain" on the motherboard work seven, KXJ127 mine explosion-proof and intrinsically safe use and maintenance of a level controller must be grounded to ensure safety inside and outside; 2 probe always clear dirt, keeping good contact electrode; a time to enable a closer look at the first three lines to ensure correct; 4 determines the level to be controlled electrode probe firmly fixed. 5 simple failure to clean up the table Symptom Look after power button is not lit Sp1117 4007 7805 5V power supply transformer, the corresponding light flashing No input power relay output lines S8050 were normal, the machine does not work TLP521 Lpc921 eight, KXJ127 ore separator explosion and intrinsically safe level controller factory Note: 1 non-electrified openings 2 maintenance should be taken to prevent sparks (be careful not to damage the surface explosion, wiring compartment cover fastening shall means introducing the seal is missing ring, watch tighten the compression nut). Nine, KXJ127 mine explosion-proof and intrinsically safe level controller out of the box and check the product package inspection should be carefully checked against the packing list box item name, signal, size and quantity, if in doubt, please contact our plant service department ten, KXJ127 mine explosion-proof and intrinsically safe level controller storage and transport 1 packaged products can be -10 ℃ ~ + 40 ℃, relative humidity less than 90% of the environment in storage for one year. 2 in maintenance, transport, storage, be sure to screw the sensor cable connector should be tightened to prevent water rust, reduce electrical performance. 3 Transport Avoid severe impact.
