What to do if an alarm is activated on Phcbi MCO-170M?
- MMr. Jonathan ShawAug 17, 2025
If an alarm is activated on your Phcbi Farm Equipment, ensure the chamber temperature and CO2/O2 gas density match their set values. Verify the CO2 gas regulator's secondary pressure is between 0.03 MPa(G) and 0.1 MPa(G), and the N2 or O2 gas regulator's secondary pressure is between 0.05 MPa(G) and 0.1 MPa(G). Check the gas tube connections and ensure the high limit alarm temperature is at least 1°C higher than the chamber set temperature. Also, check for gas leaks, an empty gas cylinder (replace if the primary pressure is 3.8 MPa(G) or lower), or electromagnetic interference. Waiting may clear the alarm automatically if caused by temporary fluctuations.
