A user facility biomedical technician (biomed) reported that an aquabplus 2000 would not power on.
The local staff had indicated there was a power disruption of unknown cause and the facilitys generator kicked in.
The generator reportedly gave a power surge to the system, causing the 24 v power supply unit on stage 1 to fail.
The power supply failure then caused the (3.
15 a) fuse that feeds it to blow.
They determined this because the fuse was replaced before the power supply, and the fuse blew again.
Upon further inspection it was noted that the cable, which connects from the motor protection switch (mps) to the power contactor, was burnt.
The 24 v supply was taken from the side and placed on the side.
This allowed the system to operate normally.
The facility ordered a new 24 v supply, and the cable that feeds the motor protection switch (mps).
There were no corresponding alarm codes that occurred during the failure.
There was no report of smoke, and there was nobody in the water room at the time of the event to notice any sparks.
The failure did not occur while patients were undergoing treatment, and therefore, there was no patient involvement.
Once the replacement parts arrive, the 24 v supply from the primary stage will be returned for evaluation.
A sample is expected to be sent back.
