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
