No
Replace the cables.
Remove the cables from the main PCB
and check PIN No.1-3 of CN43 for
DC 12V.
Is DC 12V generated?
Connect the cables and check
PIN No.1-3 of CON1 on the CO2 Sensor
Connector for DC 12V.
Replace the CO2 Sensor
Is DC 12V generated?
No
Replace the MAIN PCB.

 “0” is displayed on the MAIN PCB.
No
Replace the MAIN PCB.
Check whether K9 in the MAIN PCB is
switched off.
Is K9 switched off?
Proceed to the next
installation step.
Is CO2 level displayed?
No
Switch off the K9
and check for display.
Yes
Yes
 TROUBLESHOOTING (Continued)
After switching off the K9, reset the
power and check whether CO2 level is
displayed.
The error in the CO2 Sensor is only detected after 2 minutes when powered on.
The operation test needs to last longer than 2 minutes to be valid.
