GE Logiq E9 - Need to know what DRX temperature sensor means

April 20, 2017 10:22

I have a GE Logiq E9 ultrasound system whose "DRX3 TOP" and "DRX4 TOP" temperature sensors are reading high (75-80 degrees C). This causes the system fans to run at full speed and sometimes shuts down the machine. What are DRX3 and DRX4 referring to? Oddly, all other temperature sensors (about 30 of them) give cooler values.

Hi, DRX is refering to the Digital Receiver boards in the front-end of your LogiqE9. There are three DRX boards but four slots and it's the slots that are named DRX1, DRX2 etc. So the temperature towards the top of your DRX3 and DRX4 slots is exceeding the limits. Obvious fault first, have you cleaned the system air filters? There are two, one on the rear that is fairly obvious and a second that sits underneath the system. Look under the system and you will see a metal hook which is there to help remove and replace the filter. It's just on magnets so pull it off.

Hi Greg, I would first do a through cleaning of inside the system (air blow it) especially the Front End. Slide out all the boards in there and air blow it thoroughly.

The second thing to do is make sure the fans are operating properly, you can slide out the Front End card cooling fans (Fan Tray Assembly) and test the fans by your finger to see if they rotate smoothly.

In addition, clean the filter beneath the air cooling fans at the bottom of the system.

This should resolve the issue, if not then the sensors on one of those boards are failing.

If you have further questions, please don't hesitate to contact me: jasmaro@toptiermedical.com, we're neighbors.

I would also pull out the bottom fan assembly and make sure that the underneath the fan isn't caked up with particulates. One of my E9s had a similar issue. The filters were clean, but the fan screen was very dirty.
