MPS 3 System – Troubleshooting
11.4.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 from operator feedback and
experiences.
11.4.1.Delivery Line Occlusion/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 stopcocks and any other external devices.
•
Check the upper pressure limit settings. Ensure that they are set to the proper
levels.
11.4.2.Arrest & Additive Alarms
•
If drug occlusion alarms are raised, check the drug and delivery lines for kinks
or blockages and ensure the drug line stopcock is in the correct delivery position
prior to selecting Retest on the alarm. If Confirm is selected to clear a drug
occlusion alarm then turn the drug pump back on by selecting the drug pump
and then selecting the On button. See sections 7.3.5 and 7.3.6.
•
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, try stopping and restarting cardioplegia flow prior to doing a System
Restart or Console Swap Out.
11.4.3.Bubble Trap Errors
•
If unexpected Venting occurs, check for Micro bubbles around the fluid level
detector 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 onto
console.
•
If the Vent valve is remaining open and not closing, ensure that Vent mode is
not turned on (Vent icon on Controller will be grey if not in Vent mode).
• 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 the 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 service
personnel to replace the Fluid Level Sensor.
11.4.4.System and Internal Error Alarms (Non-Recoverable Alarms)
•
Constant System and/or Internal Errors alarms are usually an indication of more
serious problems with the instrument.
•
System and Internal Errors are designed to be displayed in instances of
possible external electrical disturbance such as ESD, EMI, and/or EMC. In
addition, the alarm may be presented due to unintentional ESD discharged from
the operator when interacting with the disposable set.
•
Occasionally an instrument will display a one-time System/Internal error that can
be corrected by following the directions on the screen. Restart system and
select Resume Case to retest. Contact Quest Medical Technical Support for
assistance if the problem persists.
