Help needed with combustible gas alarm control box
Thread Content
I would like to ask the teachers: can the power module in a combustible gas alarm control box get damaged due to aging? After replacing the power module, the display no longer shows anything
Then replace it with a new one; this thing needs to be replaced every year
If the power module in the alarm box burns out due to aging, this is a very low probability; unless the environment where the alarm box is located is harsh, in which case it is recommended to use an explosion-proof alarm box. After replacing the switching power supply, the alarm box no longer lights up; it could be due to wiring issues or perhaps the motherboard has been damaged – there are many possible causes. What was said upstairs is incorrect; our company has several wall-mounted alarm boxes that are over 4 years old, and they are all functioning properly at the moment……
This control box is used in the control room of the air compressor station in the gas tank area, and it has been in use for over four years now
