Vectra elevated motor temperature.....

[Dmorty217]

Unfortunately no. ETM ended up replacing both of mine back in January I think and the problem still existed. I continued to get the temp warnings so I lowered the power and continued to get warning as low as at 85% power. I had been following up with ETM because was told that their engineers were working on this and that they would get back to me. I have since changed the setting to reef crest and increased the speed on my 4 mp40qd's. I am very disappointed with how I cant run them in a constant mode at 100%. I set the tank up with closed loops because my wife didn't want to see any equipment in the tank....she said I could build as big of a tank as I wanted as long as there was no equipment in the tank. I achieved that with the closed loop and had amazing flow with the previous pumps I was using but I wanted to try something new to be able to control the flow and create periods when the flow is lower than others. I guess sometimes you really need to follow the "if its not broke don't fix it" rule.

At this point, I would not recommend this pump to anyone using it in an external application.

My L1 is being used at 90% during the day and 100% at night for my closed loop and though the pump is pretty warm to the touch I haven't got any motor heat warnings yet.

Great news!!!! So the ETM guy replied and said the engineers found a "bug" and it will be released in the next update! I replied "when!!!"

So ETM is saying it's a software bug that causes the pumps to run hot?

This is what he said... I'm guessing the pumps aren't running hot but a glitch in the software makes it "think" that it is...

That makes me believe that all they're going to do is raise the high temp tolerance trigger.

 

[Madehtsobi]

Yeh probably so. We can't do anything else...

I guess you could test the difference.
Those hand held heat thermometers are pretty cheap.

Well I just got an email in response to my pictures and they have no clue and didn't mention anything about finding a bug.

and now all of a sudden I am getting the temp warning running on reefcrest. I think its time to start looking for replacement pumps!!!!! :angryfire::angryfire::angryfire:

Is the pump actually getting too warm, or are you just getting the warnings?

 

[SPotter]

just getting the warnings. checked the temp and it was the same as earlier.

I'm sorry if I'm being repetitive, but I looked at previous conversations we've had and I can't find any reference to a specific pump temp.

What is your tank temp?

At top speed in reefcrest the casing is reading 130.

78

78

Yeh that is strange. I looked at my ghl controller and that night my temp tank had gone up to almost 82.. Turned off one of my fuge light fixtures and tank temps is 80 since... I wonder if that was my issue. But since yours is 78..idk what else.. Maybe just get a small fan for now and have it blow at it?

My L1 at 100% steady speed was 124 degrees.

Just for grins and giggles I put a small fan blowing over the area where both my L1 and M1 are and the temp dropped 12 degrees on the L1.

Are you running closed loop too?

Did the m1 temp drop with the fan?

My l1 is running at 100% constant and m1 is 80% constant are both in sump..

Yeah, the L1 is my closed loop and the M1 is my return pump at about 5/8 flow.

I don't remember measuring that temp.
