XF250 Controller does not work properly at alternating mode

I have two pumps connected to this controller. One on each end of the tank. My setting is pump A at alternating mode and ramps up to 30% in 30 seconds, then keeps running at 30% for 5 minutes , then ramps down to 0% in 30 seconds. Pump B is set to anti-sync pump A. However under this setting sometimes the two pumps would both run at 30% and sometimes would both run at 0% which is idle. I have another XF230 set up in my frag tank and it works perfectly fine which is while one is ramping up the other ramps down and when is at the top speed of 30%, the other goes idle. So I know something is wrong with my XF250 controller. Please help please!

As I covered in a private ticket, we do not recommend you run alternating gyre with 0 speed. Then technically all you are doing is running the pump forward and then stop which is the same as pulsing. We recommend you switch over to pulsing mode to get the same result but less complicated programming with less things that may not work as you want them to work. Alternating Gyre Mode is meant to run the pump in both forward and reverse speed so having the pump run at 0 speed and then anti syncing a second pump may give you different results.

Thanks for your reply. But I don't agree that running the pump forward for 5 minutes at a constant speed is the same as pulsing.

I will take a video of how the controller works tonight after I get home and you will understand what I mean.

Also please notice that I said I have an XF230 controller and a pair of the XF230 pumps and they work perfectly fine.

Pulsing and constant speed are directly related. You have to run the pump in constant speed and then ramp it up/down in order to create the pulsing motion you want.

I have the same (similar?) problem. Using Auto Mode, pump A set to Alternating Gyre Mode (with positive and negative values) and pump B set to Anti-Syncronized with matching +/- values. Pump A always behaves as programmed, but pump B alternates on a ~5sec schedule using the programmed +/- values. I've done a factory reset on the controller thinking that there might be some conflicting program or odd entry in nvram, but the behavior persists.

Josh,

Thank you for contacting us. Please start a private ticket and if possible, take a short video of the controller's display panel so we can see what is going on. Attach the video to your ticket and we will help you get the issue resolved or make Maxspect aware of it so they can fix it on the next firmware release.

Carlos,

I haven't had a chance to take the video yet but I did listen to you and set the controller as you suggested which is setting the max speed at +30% and lowest speed at -30%. However the two pumps still sometimes run at +30% at the same time and sometimes just go idle at the same time. I have sent you an email with photos of my settings as well as the pumps running. Please let me know what you think.

Just found out I could upload attachments here. 1st and 2nd photos are the settings I have. The rest are how the pumps run at these settings. If a video is required I can take one but it may be too big to be attached here.

Okay I have taken a video of the controller in operation but the video is too big. So I have posted it on youtube. Here is the link:

I have also emailed you the link of the video. Please let me know if you think this is still normal.
Thanks.

I am attaching the XF250 firmware upgrade file. Please copy the file as is (don't change the name) to the root directory of a micro SD card (not included). Then do the following:

1. Insert the micro SD card into the micro SD card slot on the bottom part of the controller
2. Disconnect the controller from power.
3. Press and hold the center dial and then connect the controller to power.
4. Continue to hold the dial until you are prompted to Upgrade the controller. Release the dial when you see the prompt.
5. Press and release the center dial once to select "Upgrade". The controller will update and reboot and you should be all set.

Notable changes on this firmware:
- Bug fixes
- Screen turns off after 30 seconds of inactivity. Press any button to wake up the controller.
- Larger screen font

Let me know how it goes!

Sorry for taking so long to respond. I updated and honestly, I didn't even get back to the custom program because OTC version 2.0 is perfect for what I want (and what I was expecting it to be initially). I suspect the custom programs work... I can test it if necessary - just let met know. I did see some traces of import/export functionality in the update, but it's not clear how to utilize that though the controller interface - any tips/clues you can share?

No need to test. If it is working, then just let it be.

I have updated the firmware. But because now the controller display turns off so quickly it is hard to tell if it is actually working properly. Could you share why the new firmware turns off the display a few seconds after no button is pressed? Is there a way to keep the display on?

The screen turns off after 30 seconds and you can wake up the screen by pressing any button once.
