3 TROUBLESHOOTING
The
Flowtron
®
Excel
pump unit has both an audible and a visual alarm. If a
problem occurs, the system will sense the fault and briefly flash a message on
the display. It will not alarm immediately in order to screen out false alarms
due to normal patient movement. If the same fault continues on ten successive
inflations, the audible alarm will sound and a flashing message will remain on
the display until corrective action is detected.
Note: The exception is the “F” system alarm which will be activated on sensing
the fault on the first occasion.
