PAN08 motor controller calibration

John Schmitz shared this question ago

Answered

How does the PAN08 motor controller calibration detect the end of the movement? I have a water valve that needs up/down outputs to control the valve and it appears that the PAN08 would work for this, but I need to know what it does for calibration. Or perhaps I can not calibrate it? The water valve turns the motor off internally once it reaches the limit, so there is no harm in leaving it fully powered in the up or down position. All I really need is a Z-wave SPDT switch, but I can't find that. The PAN08 looks like it could work if I can understand how calibration works internally and if it is necessary or not.

thanks!

There is a video on youtube zipatotv.

Check out.

The video on the motor controller is interesting, but it doesn't tell me how the controller senses the limits, nor does it give me a hint as to whether it would work with the valve or not. Any other thoughts? I think it might work, but I can't be sure without more information. Thanks.

I can imagine that the limits are measured via the power consumption. When it drops again, it means that movement stop. This is only an idea and you would need to test it.

Yes, that is what I would like to know. How does it know there is a stop movement? If it is a decrease in current, then this will work fine for the valve I have. If it is an increase in current (as the motor stalls?) or some other method, then it won't work. It's not easy to buy and install this, so I'd like to get a little more information before I try it. Thanks.

Dear John,

please check the attached user manual of PAN08 for your reference. You may find the command class to set the position between top and down. For the SPDT switch, please also check the attached user manual of PAN07.

any questions please let me know.

Best regards,

Pero Zovkic

Hello Pero, thank you for responding. I looked at the PAN08 manual, but I can't find how it determines the end of travel. I'm guessing that it might work by detecting current decrease which would be fine for me, but I can't be sure of that with only this manual. Is there any information on this detection?

However, the PAN07 looks better for my use. It is simpler and should work. But how do I buy it? I cannot find it for sale anywhere and I don't see it on your web site. I am in the USA. Also, can it be used with a small motor? It says it is rated for resistive loads - I don't see anything on motor loads.

thanks

the fibaro shutter 2 module is better for this. It has a few more configuration settings which are very helpful http://manuals.fibaro.com/content/manuals/en/FGR-222/FGR-222-EN-A-v1.00.pdf

I also found the pan08 modules to have a low load limit and as such wouldn't work on window motors, whereas the Fibaro would.

Thanks for the input. The Fibaro FGR-222 looks like it might work (although the details are skimpy on how it detects an endpoint - it lists a wattage threshold, but doesn't say if it detect the end by going above or below this. I'm guessing below the threshold you set.) Unfortunately I cannot find anyone selling this in the USA.

And I can't find the PAN07 either. I've contacted Philio as I'm guessing Zipato is getting them from Philio, but I don't know for sure. Anyway, I can't get these.

Still searching...

Fibaro says they won't sell the FGR-222 in the USA, but they may have something coming later this year (no specific date given). So still on the hunt for something that will work.

Nobody seems to answer this, but based on the FGR-222 manual, I'm going to guess that the PAN08 detects the endpoint by a drop in current, which means it would work in my application. I may give it a try...

hi john just a quick search of amazon finds these

https://www.amazon.com/Aeotec-Aeon-Labs-DSC14014-Controller/dp/B00FL06EZ4/ref=sr_1_1?ie=UTF8&qid=1485993919&sr=8-1&keywords=z-wave+motor

https://www.amazon.com/Zipato-ph-pan08-us-Z-Wave-Module-Controller/dp/B00KMU55O4/ref=sr_1_3?ie=UTF8&qid=1485993919&sr=8-3&keywords=z-wave+motor

exactly what is the valve you are trying to control? can you use another standard relay to activate the valve,, and use a standard z-wave module to activate that.

Hi Adrian, I have a water valve actuator that is a 120VAC motor with 3 terminals, one hot for on, one hot for off, and one for the neutral. It is normally controlled with a manual SPDT switch. Originally I started looking for a Z wave SPDT switch, but they are basically non-existent. Philio supposedly makes it and others appear to re-brand and sell it, but you can't buy them. No one has them in stock. So that's when I started looking at the motor controllers such as the PAN08. but what I cannot determine from them is how they detect end of travel when they calibrate. No one answers that question. My valve motor will disconnect internally from the power when it reaches the end. If the PAN08 or similar motor controller detects this as end of travel, then it should work. But if it is looking for something else such as a higher stall current, then it won't work. If I had that answer, I would know if the PAN08 or similar would work. Any thoughts?
