4.4. Further Troubleshooting
This section describes how to troubleshoot issues that may not be found in the
previous table. These tips and guidelines have been developed form user
feedback and experiences.
4.4.1. Max Overpressure Alarms
•
Check for any clamps accidentally left on the delivery tubing or kinks
present in the delivery tubing at the console or at the table.
•
Check for improper settings on the stopcocks and any other external
devices.
•
Check for upper pressure limit settings. Ensure that they are set to the
proper levels.
4.4.2. Arrest & Additive Alarms
•
If occlusion alarms are raised, check the drug delivery line for kinks or
blockages and ensure the stopcock is in the correct delivery position.
•
If a cartridge is not detected, ensure the cartridge is installed in the
clamp and tightened fully to engage the pump mechanism.
•
If either drug pump is listed as disabled, the pumps may be primed by
selecting the component and confirming the prompt on the Controller
to enable drug pump functionality.
•
If one of the drug pumps is behaving abnormally, with no specific alarm
occurring, rotate the cartridge to disengage the pump, then rotate it
back to reengage.
4.4.3. Bubble Trap Errors
•
If unexpected venting occurs, check for micro bubbles around the Fluid
Level Sensor in the heat exchanger. If present, stop flow and tap on
the face of the heat exchanger to release the bubbles.
•
If unexpected venting occurs, ensure the heat exchanger is fully locked
on to the console.
•
If the vent valve is constantly open and not closing, ensure that vent
mode is not turned on (Vent icon on Controller should be grey).
•
If the vent valve is constantly open and the system is not in vent mode,
navigate to the Prime screen and start the Auto-Prime process with a
primed disposable set. If the Controller does not display a yellow
message asking if there is fluid in the bubble trap, then power off the
system and contact Quest Medical Technical Support personnel to
replace the Fluid Level Sensor.
