After the password is verified correctly, the interface of opening or active submission will appear. When the device is not opened, only the request interface will appear；when the device is opened, the active interface will appear1、Connection failureObserve the LCD screen when opening, refer to the communication section for checjing, and combined with the following three points for troubleshooting    1) Check the IP port set up in the gas meter    2) Check the type of instrument selected by the system when loading(protocol)    3) Check the front engine version2、Non-open valve (LCD display, but the valve is not open)A、Prepayment gas meter1) Whether the remaining amount is greater than zero2) overdraftB、Post-pay gas meterCheck whether there is a forced closing valve in the opening parameter during the application C、Others1) Check LCD or appeal data for abnormal alarmDiaphragm meter:Err-1, hall abnormal, need to replace the hall component or check the connection lineFlowmeter: check whether there is an abnormal closing valve2)  The valve abnormalRemove the housing and check that the valve control terminal is in good contactUse 3.6v battery to drive valve switch is normal  Business operationThe operation of service is based on the meter communication with the systemRechargeAfter recharge, press the button to open the valve1、Reset the recharge amount (prepaid form)The reason for this problem is that after the application for  recharging （ the meter has not been opened), the meter data upload after the first recharge, then open the task（reset the balance when opening），So do not charge before opening.2、The amount did’t arrive1）Do not press the button to call for business synchronization2）The system recharge task has not been issued, Check the front engine task statusvalve controlPlease use alkaline battery; Do not use carbon batteries: short life and affects the success rate of appeal1、Unopened valvea）Whether there is a button to assist valve opening: single button table press the button to assist valve opening； Two-button product press the right button to assist valve opening（Press the upload button and wait 2 minutes before pressing the right button.）b）If the gas meter detects any abnormality, it will automatically close the valve and open the valve after troubleshooting. c）Close the valve remotely, check the valve control task by upper system, and exit valve control taskd）The remaining amount of the pre-payment meter is 0 or has been overdrawn，then the valve will close and needs to be rechargede）LCD display on, power supply is normal, replace the main control panel or change the meter2、Close valve conditionsDiaphragm meter1) The valve will be closed due to low voltage of the gauge.Under the undervoltage circumstance，the value can be opened by press the button；Under the low voltage circumstance，the value can not be opened by press the button；2) Close valve after receiving magnetic attack3) The balance is not enough will close the valve, press the button to open the valve4) Balance is 0, after the valve is closed, if there is an overdraft can be pressed to open the valve5) If the balance after overdrawing will lead to close the valve, the button can not open the valve, need to recharge or forced open the valve6) Idle closed valve, need to open the valve remotely7) Disconnection closed valve，need to open the valve remotelyUltrasonic gas meter8) The valve will be closed due to low voltage of the gauge.Under the undervoltage circumstance，the value can be opened by press the button；Under the low voltage circumstance，the value can not be opened by press the button；9) UMU assembly failure closing valve10) The balance is not enough will close the valve, press the button to open the valveBalance is 0, after the valve is closed, if there is an overdraft can be pressed to open the valveIf the balance after overdrawing will lead to close the valve, the button can not open the valve, need to recharge or forced open the valvef）Idle closed valve, need to open the valve remotelyg）Disconnection closed valve，need to open the valve remotelyh）Other flow detection valve closing: small flow, large flow, excess flow, reverse flowCommercial controllera） If the voltage of the meter is not enough will close the valve, the battery needs to be replacedb）Close valve after receiving magnetic attackc）The balance is not enough will close the valve, press the button to open the valved）Balance is 0, after the valve is closed, if there is an overdraft can be pressed to open the valvec） If the balance after overdrawing will lead to close the valve, the button can not open the valve, need to recharge or forced open the valved） Other valve closing Settings: broken line (signal line) storage failure3、The valve is not close1）LCD is off, but the gas can pass: valve or control circuit damage, need to change the meter2）The balance of the prepaid gas meter is zero but the valve is not closed: check whether the overdraft is set or the valve is forced to be opened by remote distribution三、parameter settingIf the gas meter has not been set, check whether the upper system has issued the command1、 Not issued: The data will sent to the meter after the meter actively appealed or pressed2、 Timeout for many times: the meter is abnormal, check whether the table has been infrared parameter Settings, such as: restore factory Settings3、Failed to issue: check the front engine CommunicationA complete communication process includes, boot (module),open SIM card,search signal search network,attachment network,connect with the front machine , exchange data with the systemThe whole data transmission time is about 30 seconds (no bit task)power dissipationBattery Life；Residential 2G/NB-IOT Alkali electricity＞10 monthsResidential NB-IOT Lithium battery ＞8Commercial controller is more than 3 years oldTechnical indicators: static current is less than 40uA(the meter is not often measured under any operation). If the indicator is exceeded, the main control board or the meter should be replacedA multimeter was used to measure in abnormal power consumption1） Replace the battery if the current meets the design requirements, and continue to observe2）Current out of range (measured by elimination)a、Disconnect the peripheral interface components one by one and measure the currentb、If the current is still large after the external component is disconnected, the main control board needs to be replaced or returned to the factory for maintenance二、MeasurementDiaphragm character wheel and LCD appear different historical data.
