When I use the GUI to set a temperature, or even just turn on the eVOLVER, every smart sleeve heats up except for the sleeve in the top left corner location. The fan works, and I get temperature and OD readings. It’s just the heating element that won’t work.
The sleeve in the top left corner does not change raw or celcius temperature values. According to the GUI, it’s raw value is ~ 2000 and temperature = 26.6 degrees.
I can feel the heating element, which is consistently cold even when it should be heating.
It worked fine for the last few months. I haven’t touched the vial since the last experiment or repaired it.
Here’s what I’ve tried so far:
- Swapping smart sleeves into the top left corner position ( also swapping the ribbon cable). Smart sleeves consistently do not heat up in the top left corner, but start working when they are moved to any other position.
- Restarting the evolver manually
- restarting the evolver from the pi
The port that the ribbon cable goes into is very clean, and nothing looks corroded.
Something that may or may not be useful: when I noticed this problem initially, I pulled out the smart sleeve at position 12 and replaced the whole thing. I didn’t try that smart sleeve on anything else. I did notice the pin at position 5 in the back was elevated relative to the rest of the pins.
Any suggestions on what to do?
