Water/Dialysate Alarms
During a water/dialysate alarm (temperature or conductivity), the blood system continues to
operate, but the dialysate fluid is internally bypassed around the dialyzer. This can be
verified by visually inspecting the flow meter in the dialysate supply line. During bypass, the
float will remain stationary at the bottom of the sight glass.
A flow alarm will not cause the machine to go into bypass. Water/dialysate alarms are self-
resetting when the alarm condition is corrected. Temperature and conductivity alarms do not
occur during the pure UF mode of Sequential dialysis when there is no dialysate flow.
Other Alarms
Other alarms may be associated with other components, such as the Heparin or UF pumps,
BPM, BVM, BTM, etc.

Troubleshooting

All status messages (operational alarms, warnings, dialogues, and advisories) are displayed
on the control panel screen. These messages are generated due to conditions and events that
occur in the machine during operation. These messages will reset when the condition causing
the message is corrected. In some cases, the operator must reset them.
