Maxspect Gyre, Icecap, Apex

[Rocklin Mike]

Currently troubleshooting a problem with my gyres with CoralVue and i wanted to share with everyone what I've been seeing in case someone has some better insight to my issue or to perhaps help another later. I have two Maxspect Gyres, XF250's, each with its own Icecap module connected to the 2016 Apex. I am also using the alternate direction modified cable for each. Both control cables plug into the Apex head variable speed ports.

The issue: I noticed a few weeks ago that one of my gyres wasnt pushing as much water as the other one. I dug into the program i had set up using one of CoralVue's walk-through videos and couldnt find any issue. I deleted the profiles and created new ones just to be sure. To confirm i wasnt losing my mind, the Apex showed about half the watts used on the lower flow gyre as compared to the opposite gyre. I swapped cables, took apart the gyre, put back together, swapped control cables, swapped power supplies. Nothing seemed to work. Contacted CoralVue and they sent a new power block without question. Hooked it up and same situation.

Then i had an idea...I turned on one of the two variable speed ports that are not in use (since i'm not using the reverse feature yet) and to my surprise the sluggish gyre fired up to full speed dang near soaking me in the process. ;Wideyed I turned the other one on and the gyre that had no issue stopped and then started flowing slowly. I then realized that my original problem was the gyre running in reverse.

More troubleshooting later, i have this info:
Gyre 1: V1 on, V2 Off
Grye 2: V3 on, V4 on
Both gyres run full speed in this setup forcing me to leave V2 off manual, V4 on manual. I checked the advanced programming and there is no code for either.

Swapped control cables only, so just swapped RJ45 connections at Apex head.
Gyre 1: V1 on, V2 on
Grye 2: V3 on, V4 off
The problem followed the cable so i'm thinking bad cable? Sent this info to CoralVue and they sent a cable to me. Waiting for it to arrive but if anyone has any ideas other than a faulty cable, please let me know. I also tried to hook up the control cables that came with the gyre but that was messing up my troubleshooting process so i stopped messing with them.

Hey thank you for the information. Let us know if the cable solves the issue

Hey thank you for the information. Let us know if the cable solves the issue

Any updates? I have the exact setup and noticed Gyre 2 is alot slower than Gyre 1 using the same profile

Same problem...,,

 

[Rocklin Mike]

It didn’t. I removed all the programming and put the speed ports to manual on and both gyres work fine and at same speed. Added programming back and one is slow again. Not sure what else to do at this point. Might be an apex issue.

Thank you for posting this my new build will have this setup as soon as my tank is done. I still need to buy 1 more gyre and ice cap module

Ever figure this out? Sounds like the V2/V4 ports were flipping back and forth causing reverse on the associated pump. That assumes you have the correct propellers in both pumps, installed in the proper orientation.

If you said they work fine with both V2/V4 set to on with no other programming, I'd probably check the programming?

I'm currently struggling with if I should bother implementing reverse into my flow schedules. Can't decide if it's worth the effort. I have my gyre's mounted horizontally and angled up a bit at the water surface. I can't decide if having one in reverse while the other is in forward would help anything as the one in forward will bounce off the opposite tank wall anyway

I believe it may be linked to orientation of the propellers. I got one of the gyres to run at max amps like the opposite gyre was running but they’ve slowly separated over the last few weeks. I’ll be checking again next time I do maintenance.
