Alarm issues when the combustible gas detector is powered on
Thread Content
It’s a combustible gas alarm that was reused from an existing installation; it starts giving alarms as soon as it’s powered on, showing error messages. Does anyone know what’s causing this? Also, should a combustible gas alarm that hasn’t been used for a long time be sent to a calibration facility for inspection? We’re reusing this device – it was working fine before, and we don’t know why it started acting this way after being moved here. We can’t find the manual online, and we don’t know how to stop the alarms. I’m asking for help from everyone out there; thank you so much!
You need to calibrate it with standard gas; if the error is too large, it means the sensor is damaged
I don’t know how the original poster found it on Baidu; https://wenku.baidu.com/view/6e81c4c0dc88d0d233d4b14e852458fb770b38ee.html – isn’t that just the instruction manual?
Just search for the instructions on Baidu and they’ll appear; how is it that there aren’t any?
Thank you. I probably have 360 set as the default; it’s difficult for me to search on Baidu every time, so I’ll change it
The main cause is likely still a detector malfunction. First, calibrate it, then check the probe or try replacing it; also verify that the wiring is correct, making sure that the power and signal wires are connected properly
If such a safe device is available, it’s better to have it calibrated at a metrology office
The measurement values aren’t showing up; maybe the wires are connected incorrectly?
Okay, thank you. I’ll go and take a look on site
