Paranormal DNA 75C Temp control issue

[lproliris]

Hello, thanks in advance for the help.

There seems to be a problem with my lost vape paranormal DNA 75C temperature control function.

Compared to: DNA 60 esquare.

Batteries are Panasonic 3400mah, low discharge rate. Classic green

Tried it with: Goblin mini v3, Innokin Ares, Vandy Vape Berserker

Wire is SS316L 28Ga, 6 turns spaced in all three atomizers. Resistances .74, .69 and ,66 Ω respectively (measured in the DNA 60, The Paranormal measures about .07Ω more).

 

When TC is activated (220C or 428F), the mod just stops giving power completely when it thinks it reaches max temperature. Result being.. no steam is produced.

I press the fire button, heats for about a second producing some steam and then just cuts off. Release the fire button, press it again, heats for half a second and stops again. And so on.

It doesn't drop the power, it cuts it off and I have to release fire button and press it again after a few  seconds for it to work. But then, it shuts off so fast I only see it worked in the device monitor.

On the DNA 60 on the other hand, the graphs are smooth and all three atomizers work fine.

Atomizer analyser shows same results in both mods fluctuating by 0.01Ω at the most.

Power is set at 15W, Preheat I have tried different values around 30W and even deactivated it.

Tried different internal resistance values that I read in forums, from 0.036 to 0.006.

I restored defaults, downloaded 316L profiles from steam and DJLsb Vapes, locked and unlocked resistance, modified  a number of parameters but the result is the same.

Without TC, the mod works OK with the temperature still fluctuating a lot though, at 15W giving max 250C or 480F, for no reason. That is why I believe the problem is the resistance reading, but the Atomizer analyzer behaves the same in both mods.

Can anyone give me some advice on the subject?

Thank you.

Have you tried setting Power to 40 watts in TC Mode?  Device will use only the power needed to reach set temperature...??

[lproliris]

I just did, no change.

The problems from what I understand are two.

When it reaches the desired temp it stops power completely, it does not adjust it to maintain the temperature.

It reaches the temperature suspiciously  fast, even with no preheat.

Below are two graphs, the paranormal DNA75C and the Esquare DNA 60. In the paranormal, the fire button is pressed for a few seconds and then released and pressed again. Everything cuts off very fast.

Thank you for your time.

Update:

Changed the atomizer, tried again with the paranormal. The graph shows some cutoffs but some puffs work. In those cases though, temperature cannot be right, it remains low.

And this is at 40W

From here I can only guess but it sounds like a connectivity problem with the 510. Use Atomizer Analyzer to get an idea if this is the case. Note when the connection starts to stop getting lower vs how many turns are left till the atty bottoms out onto socket. Compare the two mods perhaps.   The desired situation is the connection is stable about a least a turn before bottom.

Atomizer analyzer shows no problem, the fluctuation with the atomizer  I am using now is 0.005Ω.Paranormal test.csv

Since yesterday I am experimenting with the batteries as retird suggested. I do see differences but I am trying to figure out  the pattern because it looks random.

When the atomizer is heated, the issues begin.

In any case, the temperature, as seen in the device monitor, is never reached, which is not correct. It appears to be kept at around 100-150C no matter the wattage.

On the DNA60 it is very smooth.

Я не все понял из дискуссии, но у меня была подобная проблема из за того, что было установлено слишком большое значение мощности нагрева катушки в режиме ТС. При этом в первые моменты нагрева аккумуляторы проваливались по напряжению настолько сильно что мод переставал нагревать катушку( было установлено 250 Ватт, при том что на нагрев катушки использовалось не более 30 Ватт) . По ощущениям было похоже на то, что Вы описываете в своих вопросах. Вы нигде не упомянули про сообщения которые выдает плата в поле Статус.

Thank you for your time

If I understand correctly, you are asking if I enter high power, if I notice a considerable voltage drop in the battery and what the settings of the mod are. Correct me if I' m wrong

I do not think the batteries are draining fast.

I have it at 15W but tried 30 and 40 as retird sugested, with no difference in the graphs but with hotter and more steam production. Not burned.

This is the DNA 60

Here is DNA75c and what happens when the atomizer is heated.

It starts ok, after a few puffs it thinks the coil temperature is high and therefore does  not produce steam and finally it cuts off when fire button is pressed

This is with the DJLsb Vapes  316L profile.

I also use the 316L elite from steam and the standard from the escribe which I read is not good.

There are also differences between those profiles, but the big picture is the same.

If someone has a stable and correct 316l profile tested to recommend, I would be much obliged. Just to eliminate one parameter.

Thank you.

 It looks that the problem is this. I have to tighten it well to achieve stability AND lower resistance value.  The resistance changes by  about 0.1Ω  when I start unscrewing.  After cleaning, screwing and unscrewing many times I got a number close to the one I wanted and it works well since. (5 hours).  Previously, I turned it till bottom, saw the value being stable for a minute and I thought that was it.  What was happening afterwards without me realising is that due to some movement or temperature change, the values changed. But I was watching the device monitor. So, the value has to be low as well.

Thank you for your help.

The problem remains, the mod is unreliable. From now on I will have to have it connected to a pc and play with the 510 in order for it to work?

Is there any way to fix it? Buy a new 510 and solder it or something? I'm afraid I will damage the insulation but if necessary,  I'll do it.

Have a look at this post, it should be helpful.

https://forum.evolvapor.com/topic/69140-paranormal-75c-resistance-too-high-fix/

I suggest you read the entire thread, it was later determined that the wires need not be removed to do the fix.

Thank you all for your help.

I will do that.

I had seen the post but thought it wasn't  helpful to my case due to instability in values and not just higher resistance. Anyway I will try it and see what happens.

 I will be surprised if it is anything other than what ThatGuySwain posted about. For awhile is was a very common problem. Back then if you had sent your mod to Evolv, he would be the person repairing it.

Well, I had an issue with my DNA 75C some months ago as well. 

I do TC vaping and use titanium wire mostly. One day, my mod started to misbehave. It was not cutting any watts during temp control vaping. The temp was set to 230 C but it was rising to 275-280 C, mod was not reducing power at all.

What I did is a soft reset and after that a hard reset. After the hard reset, it came back to normal, working once again as it should.

Try it out.

Thank you for the advice.

I cleaned the connection and thinks got a lot better.  Still though, it does burn the resistance (carbon on the surface) faster than expected. This is a matter of SS profile.

I will remember your experience in case something like this happens in the future.
