Thanks koh. Can you tell me where to find the water jacket pump or what it looks like? Then I'll let you know what I see.

Thanks koh. Can you tell me where to find the water jacket pump or what it looks like? Then I'll let you know what I see.
The water pump motor, is the only other motor inside the housing other then the main rotation and lift motor, as far as i can remember it is mounted vertically inside the housing, facing down. But my memory might be off.
Let me know if you find it.
Perhaps you can take a shot of the inside of the unit and i can point it out to you.
Thanks.
Sweet. Looks like you nailed it with the pump. I've been down under the tanks before, but never bothered to pull it out. I assume this is what you were talking about since it's the only pump I see. I believe this is what circulates the water in the base during the color processes. It was set horizontally in a slot underneath the chemical tanks.
As you can see from the attached photo, something is very wrong with it. Near as I can tell it still circulates water when running, but judging by it's case it might very well be the culprit.
You indicated you may have parts of these. Is this something you have available?

Yup this is the pump the circulates the water. And yours is quite dead.
When it over stersses it will draw more power, with the heater on and the processor warmer with the hotter process the board power eventually fails, and starts back up when it cools down.
I will get a price for you ASAP, but will not be before next week. I can special order it for you, as i do not have one in stock at the moment.
Please give me your email so i can contact you directly off the board.
Great that you found it.
Sounds good. Thanks so much for helping me find it. Email is gavin@seimstudios.com.

Turns out I've got the same problem...
ATL skrewed up 12 trannies :-(
Cleaning program works well.
The first E6-3bath run I did also worked out (125ml, 1x120).
But directly after that, the second E6-3bath run (500ml, 12x 4x5) died during the color developer stage...
If someone has service manuals, please mail them to martin.jan.koehler _AT_ gmail.com
Thanks,
Retested with water instead of chemicals and films ...
1) Cleaning stage went well,
2) then a first 500ml E6-3-bath went well,
3) but then during the second 500ml E6-3-bath the ATL shut off during pre-heating the chemicals (before the first bath).
I measured the temperatures in the water bath, both bottom corners, left and right of the drum (at the head of the drum it was 42° celsius).
Is that too hot?
I'm using the main water inlet (tempered pressure).
But as there was no external pumping involved at this stage (heating stage right before First Dev) ... could that have to do with the heater?
Best regards and thanks,
Martin
Martin,
Your problem is most likely linked to the water jacket pump. This is the pump the circulates the water through the machine, and works ALL the time while the processor is on.
You should remove the main cover an inspect the pump (it is blueish, see the photo above). When the pump is that dead, it will work fairly ok when on low temp, but as soon as the temp starts rising it will draw more and more power from the main board until causing the main PCB to overheat and shut down. Once it cools down a bit it will start back up.
The heat you mentioned is fine and within spec, as the water jacket temp is normally higher then the actual process temp to help maintain the exact correct temp in the bottles and rotating drum which are all exposed to room temperature air. you are 3.5 C over the process temp (jobo calls for 3.0C but you are still fine).
So - look for the pump and get back to me.
If it is dead, it will need replacing.
Good luck.
Thanks, I'll open the machine after work and look for the pump ...
One other strange thing I noticed ... there's always 1°C difference at the left corner of the water bath to the right corner of the water bath.
The left corner near the head of the tank is always 1 degree hotter.
Is that normal?
Does this water jacket pump also the do the circulation in the water bath?
Best regards,
Martin
