On mortar automatic packaging machine applications weighing controller DX8808M-2

DX8808M-2 weighing controller Manual 1 Introduction DX8808M-2 after weighing controller is designed for the chemical, food, cement and other valve port packaging machine to provide quantitative precision intelligent automatic control equipment. It has a simple, easy calibration, stable performance, double valve, precision and other characteristics, which uses dual-panel design, with good anti-jamming capability, it can be reliably used in the complex, harsh environments. 2, the working principle type DX8808M-2 dosing controller to the analog signal acquisition sensor output, the imported chip integrated data processing, will be weighed value of materials used LED display. Also shows the value of the weight of the material after high-speed computing and computer programs set value, if the weight value reaches the set value of the controller output signal to the control device, in order to achieve stop feeding, out with other intelligent action. 3. Technical Specifications 1 Power: AC 220V + l0% ~ -15%, 50Hz ± 2%. 2 power: 9W. 3 Working temperature: 0-50 ℃. 4 Working Humidity: ≤90% RH (non-condensing). 5 Four 12V output ports, control solid state relays. 4, the use of power, the signal retrieval is complete, ● start / stop lights. After the warm-up 30 minutes, press the "Clear" button to start the entrainment to work, ● crude stream, ● trickle indicator lights, the output control signal, when the weight reaches the set value of the corresponding ● crude stream, ● trickle lights off, stop output control signal, and then push the bag indicator light ● Push bags signal output, will complete a work cycle. 5, parameter setting press "Settings" button, the controller displays L1 20.00 while crude stream ● indicator light flashes on the right display area, indicating that the weight of the material can be adjusted via the numeric keypad. Press the "OK" button, the controller into a trickle weight setting state, the display L2 15.00 ● thin stream while light is on, you can adjust the weight trickle through the numeric keypad. Press the "OK" button, the controller displays L3 2.00 ● While pushing bags lights, you can adjust the delay time to push the bag through the numeric keypad. 6, weighing scales precision controller calibration operation of the entire weighing batching system is composed of weighing sensors, batching controller, said the accuracy, reliability, and other parts of the body coordination parameters such as quality assurance, thus compounding work batching equipment before, it must be calibrated scale operation. DX8808M-2 ingredient controller only in the "stop" state can be calibrated scale operation. To ensure the accuracy of the calibration scale value, the user must be half an hour after the controller is powered on, be calibrated scale operation. The sensor cable securely access controller. The scale is balanced, and to ensure that the sensors used by a consistent force. Otherwise, the scale body should be adjusted. The controller is powered on, it is the "stop" state, only the "stop" state can be calibrated scale operation. It should be recognized within the weighing hopper scales before school is empty. Enter the school scale Password Key 6.1, the controller flashes to change the password, the controller display button, the controller automatically transferred to the following "school zero" state. If the password is entered incorrectly, the controller will automatically return to the "stop" state. 6.2 Zero calibration (J0) as entering the correct password, the controller displays, in this state, if the scale body stable for about one second, the controller displays, showing "zero correction" is completed, the controller automatically transferred to the following The "school end" state. 6.3 School endpoint (JC) enter school end state, the controller displays, you should put the standard weight in the weighing hopper, if the weight of the standard weight of 1000 kg. By pressing the corresponding number key will display window 2 the value to weight the weight value 1000, the controller should show, to be stable scale body, keys, school scale operation is completed, the controller automatically returns to the "stop" state. Remove the weights, the controller display should return to zero, add the standard weight, the display should weight the weight value. If it exceeds the error tolerance, check the scale body is balanced, the force sensor groups are the same, until the scale body to adjust, recalibrate the scale. NOTE: The weight of the minimum weight at school end value of 100 points. 7, controller wiring diagram
