Alternate O2 and vap warning on system startup

After system start up there are two popup boxes located at the top of the machines checkout screen that say "Set Alt O2 Flow! Check Agent Setting!".

Other machines do not display this message and this only happens when first powered up. If you restart the machine this message does not re-appear.

Could this be aproblem with the Alt O2 switch, mixer, transducer issue or something else?

* Machine has version 8.01 software

Could be a mixer problem. In your maintenance menus check the logs if there is a fault it will show up there. Also if there is a fault with the Alt O2 switch it will show up.

You should first check the machine error history log for more information about your issue. The technical service manual has documentation for each of the error messages found in the history.

It could be your mixer assembly, which is typically a defective solenoid. Performing a zeroing or calibration on the mixer. You could even have a defective Alt O2 switch or harness causing your problem.

Try bleeding all the gas from the machine.  Start the machine and let it go through initial test then plug in the wall gases again. If the message clears then It could be your O2 or ALT o2 valves on the mixer board not zeroing ( check error codes ).  Cheaper to replace those.  Also try calibrating the Mixer board in the service section. Otherwise changing the Mixer board will generally fix the issue.  If none of that works then its possible for it to be the ALT O2 switch.
