I have Valve fail or Valve over inject alarms, what do these mean and what do I do?


If you see a Valve over inject Alarm, ensure that the Solenoid ‘flow stop’ on the gas block is open and ensure that the O2 cylinder is open. If no Oxygen is getting to the solenoid the solenoid will inject more frequently than the software expects and indicate Valve over inject. Next re check that the O2 cylinder contains Oxygen, if it contains less than 100% Oxygen the solenoid will fire more frequently than the software expects to attempt to maintain set point.
