™ Portable Oxygen Concentrator

3074

Err Sys HIOOR

This alarm is only applicable during normal operation mode.  The oxygen sensor heater positive voltage was below or 

above a predefined range.  The heater positive voltage can be directly related to current based on the resistor value in 

the circuit. Check the oxygen sensor's heater positive voltage output for a connection and proper voltage (low limit is 

1.2455V; high limit is 2.471V).

3075

Err Sys HVOOR

This alarm is only applicable during normal operation mode.  The oxygen sensor heater voltage drop (between the 

positive and negative outputs) was below or above a predefined range.  The heater voltage drop represents the voltage 

across the heater coil. Check the oxygen sensor's heater positive and negative voltage outputs for a connection and 

proper voltage (low limit is 0.6275; high limit is 2.422V).

Alarm - Stuck 

Button

Membrane Switch Held in Down Position while the processor was starting after a reset condition. Make sure no 

buttons are pressed after the unit has been told to power down. Check the membrane keypad for a permanent closed 

button position.

3840

Alarm - Low Flow 

Output

This alarm can only occur on Continuous Mode.  The output flow from the proportional valve is 10% of the desired 

flow level.  This condition has a guard during a flow change of 6 shift counts.  This guard condition will prevent false low 

flow conditions from being detected whenever the user changes the Continuous Mode setting. Check to see that the 

proportional valve plumbing is correct. Check to see if the proportional valve is working correctly.

4099

Maximum Shift 

Time Exceeded

The time it took the sieve beds to shift is too long at the present altitude.  The maximum allowable shift time is 

independent of the flow setting.  The maximum allowable shift time is 30 seconds. Check the connection between the 

product tank and the pressure sensor. There is a leak in the pressure hose. The pressure sensor is not working.

4352

Warning - EXT 

PWR Low

External Power at < 11.0 VDC for 250 consecutive samples in a 1.5 second sampling window.

4608

Alarm - EXT PWR 

Low

External Power at < 10.0 VDC for 250 consecutive samples in a 1.5 second sampling window.

4096

Alarm - Fan is not 

moving

Not Applicable. This alarm is not used anywhere in the program code.  It had been used in the XPO2 product, but the 

hardware of Solo2 does not support FAN feedback.

4097

Alarm - High 

pressure

Pressure reading at transducer is above 18 psi. Check to see if the PE is operating correctly. Check to see if the S1I and 

S2I valves are operating correctly.

4098

Alarm - Low 

pressure

Pressure reading at transducer is below 1.5 psi. Check to see if the PE is operating correctly. Check to see if the S1I and 

S2I valves are operating correctly.
