Troubleshooting

The XPO has dozens of alarms that are being monitored on a continuous basis. The
2
alarms are grouped into four main categories:
• Common Alarms: These are alarms for which the patient, or the provider, can take
action to eliminate the issue. These alarms, and the corrective steps, are fully
explained within the Owner's Manual (OM).
• Operating Alarms: This alarm group centers on the sieve beds and the PSA
process. These are alarms for which there is no corrective action available to either
the patient or the provider. However, there are sub‐codes that can be accessed to
help the Invacare service and repair centers.
• Compressor Alarms: This alarm group centers on the compressor operation. These
are alarms for which there is no corrective action available to either the patient or
the provider. However, there are sub‐codes that can be accessed to help the
Invacare service and repair centers.
• System Alarms: This alarm group centers on internal software monitors. These are
alarms for which there is no corrective action available to either the patient or the
provider (*). However, there are sub‐codes that can be accessed to help the
Invacare service and repair centers.
To access the Sub‐Alarm codes, the unit first has to be in an alarm condition with multiple
flow level LEDs illuminated. While in this condition, the Plus (+) and Minus (‐) flow
setting buttons should be pushed and held. As long as both these buttons are being
pushed, a different set of flow LEDs will illuminate. This alternate set of illuminated LEDs
is the sub‐alarm code. Once the Plus and Minus buttons are released, the original alarm
code will return. Once the unit is turned off, the alarm codes displays will be reset. All the
alarms should be reset and the unit turned back on to see if the unit can self‐correct the
problem. If the alarms persist, please contact your nearest Invacare repair center.
