如何选择并安装气压报警器

当气瓶没有气体时，机器工作实现实时报警，可以使用本功能

一.气压报警器的选型：

需使用无源的常开/常闭类，因此可选择膜片式可调压力开关，建议使用型号[QPM11NO常开]

如您使用的报警器为有源高低电平输出，请使用继电器转接为无源信号

二.报警逻辑：

在焊接动作开始后，按照预定设置的电平来检测信号接口一的1/2脚的电平

三.安装方案：

1.气压报警器应接在气阀出气端

2.两根无源信号线接在信号接口一的1/2脚

3.如使用型号为常闭，则系统设置里面的气压报警电平为高电平有效，否则设置为低

四.附件

When the gas cylinder is empty, the machine will trigger a real-time alarm to indicate this condition, and this function can be utilized

I. Selection of barometric pressure alarm:

A passive normally open/closed type is required, so a diaphragm-type adjustable pressure switch can be selected. It is recommended to use the model [QPM11NO normally open]

If the alarm you are using has active high and low level outputs, please use a relay to convert it into a passive signal

II. Alarm logic:

After the welding action begins, detect the voltage level of pin 1/2 of signal interface 1 according to the preset voltage level

III. Installation Plan:

1. The air pressure alarm should be connected to the air outlet end of the air valve

2. Connect two passive signal lines to pin 1/2 of signal interface 1

3. If the used model is normally closed, the air pressure alarm level in the system settings should be set to high level effective; otherwise, it should be set to low
