Installation Notes

Instructions for use

  1. After the power cord is plugged in, the power indicator flashes, and the LCD display shows as shown in Figure 2; the preheating is 4 minutes, and the number code HO is displayed (the code HO indicates preheating). The number is reduced from 240 per second. During this period, the product is in the preheating state, if the gas injection product will not emit an alarm sound at this time; when the number is displayed to 0, the system will automatically enter the working state;

2. In the state shown in Figure 3, the green power indicator is always on, indicating that it has entered the working state; at this time, the alarm will be able to detect the gas normally; the time on the right is my real-time time;

3. When a gas is detected, the corresponding concentration will be displayed on the display screen; as shown in Figure 4; the concentration of carbon monoxide is 200PPm, and the concentration of gas is 10LEL;

Figure 4 Figure 5

When the concentration of carbon monoxide gas is greater than or equal to 200 PPm, the red indicator light of carbon monoxide flashes; or when the concentration of gas leakage is greater than or equal to 10% LEL, the red indicator light of gas indicator alarm flashes; and "嘀-嘀-嘀" is issued "Sound; after the alarm lasts for 8 seconds, the valve signal or digital signal will be output; and the alarm information will be recorded;

4. When the display of Figure 6 or Figure 7 appears, the fault yellow light is on, and the buzzer emits a constant beep, which indicates that the sensor part of the product's automatic detection needs to be replaced. Sensor part is broken;

Figure 6 Figure 7

5. When Fig. 8 or Fig. 9 appears on the display, the faulty yellow light flashes and the buzzer emits a constant beep to indicate that the product automatically detects the product's reverse drift; Figure 8 shows the CH4 reverse drift, Figure 9 It is the reverse drift of the carbon monoxide sensor. At this time, the alarm should be powered on for a period of time to see if the product can recover automatically. If it cannot be recovered, it should undergo professional zero calibration or calibration;

Key operation

键用于操作手动关阀或则改变操作数的大小; The valve key is used to manually close the valve or change the size of the operand;

键用于进入菜单操作和确定功能操作; The menu key is used to enter menu operations and determine function operations;

键用于进入自检功能或操作时移动操作位; The self-test key is used to enter the self-test function or move the operation bit when operating;

Self-test function operation:

不放,蜂鸣器发出声音,所有指示灯亮,LCD所有段码都点亮; Press and hold the self-test , the buzzer emits a sound, all the indicators are on, and all the segment codes on the LCD are on;

Close valve operation:

键不放,5秒后会关闭阀门,LCD显示5至0的变化.如果LCD显示数还没到0时候,松开了此按键,此时不会关闭阀门; Press and hold the valve key, the valve will be closed after 5 seconds, and the LCD displays a change from 5 to 0. If the LCD display has not reached 0, release the button, the valve will not be closed at this time;

Silence function operation:

阀门一次,可以关闭报警声或故障声; Press the self-test and the valve at the same time once to turn off the alarm sound or fault sound;

After the silence, if the concentration is restored, the sound will sound again. When the other gas alarm is silenced after one gas alarm, the sound will sound again;

Set time

键后,出现如图10示,按自检键将光标移动么设置位置(光标在的位置,相应的文字会闪动),再次按菜单进入设定时间界面和密码输入界面; After pressing the menu key, as shown in Figure 10, press the self-test key to move the cursor to set the position (where the cursor is, the corresponding text will flash), press the menu again to enter the time setting interface and password input interface;
