Issues with 6105 and 7095

[KJoFan]

I’ve got two 6105’s running on a 7095 controller. As I understand it, how I have them programmed one should run at 30% while the other runs up to 100% and then switch every 6 hours.

However, I keep having one pump not working. I have to unplug it from the controller and power supply, plug back into controller and then power supply and it will work again for awhile.

Do I have something set wrong?

I have a VERY similar program just on the apex and mine does the same thing. If I hit feed and cancel real quick they fire back up. But routinely one of them will remain off for its whole “turn”. Luckily mine switches every 2 minutes so it never is off for long but it happens often.

I have two 6095s on that same controller and they behave the same if there is any power fluctuation (storm or something). I have to reset the box to get them work again. This just started happening to me about a month ago. They are not connected to the internet or anything so I'm not sure what is going on here.

Good to know I'm not alone, but it sure is annoying!

If your pumps are the newer type with built in 7090 controller, they will need to be calibrated as shown in this video. The 7095 is a much older controller, it came out in 2004 and uses a 0-8V control signal, the newest pumps made since mid 2015 with 7090 use a 0-6.5V signal and will generally stop at speeds below 50% unless this calibration is done to sync the control voltages. The same applies to 7096. If you have older model pumps without the 7090, the cause is likely a binding drive unit, please let me know.

Do those instructions exist in English?

I purchased the pumps used so unsure of their age. Is there a way to easily tell? They don't have the 7090 built in controller.

They are subtitled in English.

The pumps have a date code on them, if they don't have the 7090 then something is binding mechanically, the date code will be on the hexagonal body that houses the motor that the drive unit inserts into, it will be 4 digits on one of the long side walls, usually it in month and year, rarely they have used week and year if they are older.

I don't think they are ancient, as they do have the somewhat newer blue rubber, four point mount to reduce noise. I will have to look for the date this evening.

ETA: I was told by seller (looking back) they were purchased August 2013. Unsure if they purchased new, but maybe you'll know if that fits the timeline at all?

I would suspect either the shaft is loose, the disk is worn out or the drive unit is worn, it is more likely a pump issue than a controller issue in that case. The rotor will bind up against the side wall and stop at low speeds when something is not perfect with the drive unit.

I will see if I can inspect it tonight and take photos if needed. I agree it must be a pump issue as I actually have two 7095 controllers and it does it with both controllers.

It’s going to be comical if it is the pump damaged from wear and tear and my 5 year old Jebao WP’s are running like new.

Snark alert!

What would be amazing was if you got a quick response to any technical questions you had from Jebo. You would have to resort to throwing the pumps away and replacing them.

Instead you could get a great response and service from Tunze like I have for years. In fact Roger just supplied me with parts for a 15-20 year old pump for a skimmer. How is that for longevity and service? I have lots of Tunze items that are still running after more than 15 years. Classics never go out of style the just keep ticking. Quality starts with proper design and testing.

Tunze great produts and great service.

I’m unable to see anything obviously wrong:

Do you have contact information for him? Now my right tunze won’t turn on at all
