3 TROUBLESHOOTING
This section lists some of the problems which may occur after long periods of
time, and outlines the way in which to correct them.
The
Flowtron DVT
System has an audible and a visual alarm.
When a fault condition occurs, the audible alarm sounds and the red LED
illuminates.
The following checks should be performed by a trained Huntleigh Healthcare
person.
3.1 Preliminary Checks
Check the following before dismantling the pump unit.
1. Verify that all tubing connections on pump and garment are securely
fastened and in place.
2. If alarm still sounds, visually inspect tubing and garments for punctures
or tears.
This eliminates possible garment and tubing faults.
3.2 Further Checks
If the alarm stays on it could indicate:
3.2.1 Low-pressure fault
Check position of pressure control knob.
The alarm will sound if the pressure in the garment does not reach 28 mmHg.
Adjust pressure control knob if necessary. Refer to Section 4.
3.2.2 Constant-pressure fault
Switch the pump OFF and remove garments.
A constant pressure fault condition occurs when the timer motor stops rotating
(air not alternating). If this should occur, check integrity of the electrical
connections of the timer motor. If connections are sound and the motor still
does not rotate, the timer motor must be replaced.
