Title: XPFM for a fan
Post by: steven r on July 20, 2007, 12:45:32 PM
I just got my XPFM installed with a little help from Mr Sparky. I called them in because I expected that the install would need to be in the attic. As it turns out we figured out an easier way to wire it inline that I might of been able to do myself.

Now for my challenge...
At every fan speed other than the highest speed when I send the XPFM an off signal it will immediately click back on. At the highest fan speed everything is ok. Is this normal or do I have a defective XPFM.

Does your fan have lights? If so, turn on the lights, does XPFM still turn back on?
Title: Re: XPFM for a fan

I checked and the lights don't have an effect. My lights and fan are wired independently.

Could you tell us more about the speed control or, better yet, give us a make/model number so we could look the manual for it up up on the web?

I wish I did know the model. A manual would be helpful. As this is a high ceiling, I would need a latter to reach it that I don't have. It's a standard "builders grade" fan that came with the house, less than 5 years old. The fan has your standard pull switch.
i.e. fast/med/slow/off

My guess is that one of these would apply:

Generic Ceiling Fan Wiring Diagrams (http://www.hurontel.on.ca/~taitg/pages/cfan.html)

I'm not sure what's going on here but I suspect back EMF from the fan motor in reduced speed mode may be triggering the XPFM module back on.  Maybe someone else on the forum can chime in on this discussion.

So power is supplied to the XPFM through a standard wall switch?

Any chance you have a "shaky" neutral connection to the XPFM (picking up noise on the neutral)?

Short of that, OldTimer's theory of back EMF is the only other effect I can think of.  Without knowing how your fan speed is controlled (capacitor, tapped motor windings) it's hard to say what the phasing/amplitude of the back EMF is doing at low speed.

OldTimer - nice fan diagrams.  I'm having problems figuring out the first diagram though.  Seems like the speed control table doesn't match the diagram.

...So power is supplied to the XPFM through a standard wall switch?...
The fan and the light were originally both controlled by separate wall switches. The XPFM replaced the fan's wall switch. In addition the light & fan have pull switches on the unit themselves.

...Any chance you have a "shaky" neutral connection to the XPFM (picking up noise on the neutral)?...
If it did, wouldn't it be more likely to shake at the higher speed? Remember it's on the slower speeds that the switch turns back on.

It's looking like I'm going to need a ladder to see if I can figure out what to model number is. Fortunately the identical bedroom fan will be easier to reach.

Actually, I was trying to ask if you might have a poor neutral connection (high resistance) which could cause the XPFM problems.  Sorry for the poor use of the word "shaky".

Since you brought up the fan speed - an unbalanced fan at low speed will exhibit a lot of displacement (motion).  As the speed goes up, the frequency of oscillation will increase and the actual displacement will go down. 

It would be a real reach to imply the your fan movement was pulling on the wires and causing a problem with the electrical connections.  If I were to imply that your electrician would probably be justified in paying me a visit to explain things in detail.

Fortunately the fan in my bed room is identical and I was able to view it's label by standing on my bed. So far the numbers haven't helped me google a manual but I'd loved to be proven wrong on it not being on the web.

The numbers I found on the label are "HC1131", "82H4" and "EB1964". It's a 52 inch fan and it says it's .75 A at 120V.

Boiler: The diagrams are off the Web as a result of a Google search.  Not my work.  I looked at the first one again and can see why you questioned it.  In my opinion it is OK.  The speed control seems to be coming from an unspecified capacitor with two elements in it, probably a larger and smaller.  In that case the switching table would appear to be logical.

I hate to send you up on the bed again but is there any chance that there is a UPC (bar code) label on the fan?  If so give us all the numbers under the bar code.  Usually a single leading digit, then two groups of multiple digits and a single trailing digit.

I Googled your numbers and didn't get anything either. Very frustrating!

Thanks

The only reliable hit I get is for a Craftmade 52" fan with a "EB" in the model number.  Nothing on manuals or motor configuration.

Don't know where my earlier response went, but I have seen this before and Oldtimer pegged it. Large back EMF spike develops (because of the cap) when the XPFM opens the relay. This is confusing the local control. Interestingly I have had this problem crop up on Appliance modules which worked fine for long periods and then suddenly developed the problem, which to me says perhaps something in the module fails or "ages" (zener clamp?) in the module.

Can you connect a light (40W - 100W or even a 7W nightlight on an extenson cord, sans plug) across the fan leads temporarly? If the problem goes away then the local control is being falsed.

You might try another module.

Probably isn't much help.

Hmm.. I wasn't aware the XPFM had local control but just verified it does.

...Can you connect a light (40W - 100W or even a 7W nightlight on an extenson cord, sans plug) across the fan leads temporarily?...
Once I locate an extension cord that I can sacrifice by cutting off the plug I could make a test cord to plug a light into. The XPFM is mounted in a double gang box with a blank plate over it so it is easy to reach. (I have a picture but my editing software to reduce to an acceptable size is on my laptop and my lap top is holding its contents hostage till I find replacement memory for it.)

If putting a light in parallel works, does anyone have a recommendation for a small light that would work that I could wire in parallel and mount on the blank plate?
Title: Re: XPFM for a fan
Post by: dave w on July 23, 2007, 02:33:33 PM
Aw yes, the old night light in the wall trick... ;D

Yes the XPFM is just an "old brown appliance module" with attached wires. If you don't mind voiding your warrenty,  try disabling local control. Go to Ido's site or Google "appliance module modifications". Look for a jumper on the board going to pin 7 of the chip.

Here's a possible answer to your question that doesn't involve a light. (http://www.x10community.com/forums/index.php?topic=9281.msg57138#msg57138)  The resistor could go in the box with the module but would have to be insulated with tape or shrink wrap tubing.  However dave w's suggestion about defeating local control is a much better idea as far as I'm concerned.

I tried a XPFM in a test bed and mine didn't seem to have Local Control. Though it was not inductive just a 40 watt bulb connected and disconnected to the output.

Interesting - I wonder if there are different models of XPFM. And,  if it isn't local control sensing , then what is left to explain the XPFM turning back ON only when fan is set on medium or low speed?

I just sent a note to Rye asking about a WS467 problem. If he responds I will try and ask him about this. I am sure it is Oldtimers EMF theory. I have an Appliance module controlling a ceiling a fan doing it and a couple of appliance  modules controlling Xformers which sometimes do it. In each case a night light in parallel with the load stopped the action.

Sign me perplexed

Post by: steven r on July 23, 2007, 05:36:14 PM
Since the XPFM is sold for florescent fixtures as well, having local control isn't really a great idea. That said I turned my fan off, pulled the fan chain till it cycled through off and then back on. Sure enough the XPFM clicked and the fan came on so mine has local control even though I'd rather it not.

...Yes the XPFM is just an "old brown appliance module" with attached wires. If you don't mind voiding your warrenty...
I don't mind doing the mod. While I'm inclined to agree that the XPFM circuit is basically the same as an "old brown appliance module", the layout inside my XPFM is significantly different from the online appliance module boards. e.g. The chip is on the opposite side of the board from as the other components and turned 90o. I'd be guessing as to what lead to cut.

So what size resistor do you recommend and will it effect energy use significantly?
Title: Re: XPFM for a fan
Post by: Boiler on July 23, 2007, 05:45:53 PM
steven,

Installed 2 of these on ceiling fans for my father ~ 2 years ago.  If they had local control (I don't believe they did) his fans didn't activate it.  The fans are about 15" in the air and are run at mid speed.

I definitely agree that having active control on this unit is more of a detriment than a asset.  The X10pro site lists nothing about local control for the unit.

Another case of a module being "enhanced" without a model change/notice?

If you and Brian_H could post date codes and firmware versions, I'll add them to the database.

Yeah and some where I think I read that it responded to an "All Lights On" also. Fortunately it doesn't.

Sorry, I left the URL out of my original "resistor" post above.  I just put it in so look at it again. As you can see this was intended for a different problem but may work for you at a lot less current drain then a night light.

Why did SHRINKING the GIFs make them grainy? I would have thought smaller would be sharper, as with viewing Basic (lowest bitrate) TiVo/ReplayTV files on a 21" TV vs a 60" TV. ???

Follow the trace coming off pin 7 of the chip, do you find a jumper" If so, try snipping the jumper. It will be easy to re-tack with solder if cutting it does not disable local control.

An over simplified way to think about it is...
If you have an image with a resolution of 72 ppi (pixels per inch) and the image is 4 inches wide you have a total of 288 pixels in the width of the image. If you reduce the width by 50% the image is now 2 inches wide. Two inches at 72 ppi now totals to 144 pixels for the total width of the image. Reduce it another 25% making it 1 inch wide and you have 72 pixels for total width. When you do this it becomes grainy. To get around some of the grain, the image can be saved with a program that can save the image using the "Bi-cubic" method. The bi-cubic method is just one way of controlling the image gradient color range. (Keep in mind that PPI displayed on a monitor vs printing outputs a bit different)

If you convert the image into a "jpg" then shrink it, it would come out a bit better. A good rule to follow for image format is as follows.
GIF - used for sharp line art type images with solid colors. (GIF format uses a max of 256 colors) Non Anti-aliased images. Images with animation or transparent backgrounds.
JPG - used for images with continues color up to 16M. Photographic type images, anti-aliased images.

There are a ton more reasons for using either or and for using other formats as well.

Steven R -
There are 2 models of the inline unit, XPFM and XPDF.  Only XPFM provides local control natively.  The other model allows you to wire a local switch inline to ADD local control.  That one also allows dimming, where I believe your's doesn't.  The piece of printed scrap paper (instructions) that was in the package goes into short deatail about it.  Your situation is frustrating becasue you actually don't need the features of the XPFM you need the XPDF with abiltiy to handle inductive loads.

As far as why it functions fine in HIGH but turns itself back on in Med and Lo, my thoughts are this...
Local Control functions by sensing load.  When your fan is in Med or Lo speeds, there is inductive resistance placed on the line to slow the fan down.  So, if you turn the fan off with X10, that command goes thru, the fan turns off, and then the resistance is what triggers the fan back on.  In High, that is not present, so the fan goes on and off like you want it to.

The inline units are great tho... after I've put my 1st one in, I am going to do many more.  Even gonna wire one into my cabinet-mounted microwave to control the lights there.  Other cool ideas pending.

waterstom,

I think you've swapped your unit designations.

The XPDF is specified for resistive loads only and has warnings regarding it's use with motor, low voltage, or fluorescent loads.

X10 pro link : XPDF (http://www.x10pro.com/pro/pdf/xpdf.pdf)

The XPFM is claimed to be designed for 15A inductive or appliance loads.

X10 pro link : XPFM (http://www.x10pro.com/pro/pdf/xpfm.pdf)

The XPDF specification does mention local control.  The XPFM does not.

I am having the exact same problem with an in-line XPFM.  I have installed it on a new fan, with no wall switch at all---just the XPFM, mounted inside the  canopy of the fan.  With the fan pull chain on high speed, it works perfectly.  Also with the pull chain to the "off" position, it works (you can hear it clicking off).  With the pull chain in the "low" or "medium" position, you hear the XPFM clicking off and immediately back on.  EVERY TIME!  It will not turn off.  Can anyone help more?

Post by: cksedg on January 17, 2008, 01:30:40 PM
Ok---after reading everything I can find about the XPFM, I am convinced my problem from the previous posting is from local control.  I have disabled local control on a regular plug-in appliance module by "snipping" the wire from position #7 (found several diagrams out there on the internet); but I have not done it on an XPFM.  Has anyone out there done it, and is it essentially the same as the plug-in module?

Any help---with a diagram or actual picture---would be appreciated.

What is the date code on your XPFM

If that's the white sticker on the back... 10E19 (I think it's a 1... the first number is a bit smudged off).

FYI - I tried the resistor solution offered in this thread and the fan won't even turn on with the resistors coming off the blue (switched) lead from the XPFM.

Also.... if I hold the blades, it will turn off without turning on and if I hold the off button on my 3 button stick on wall switch eventually it turns off (sometimes) after turning back on several times.

I think it's definitely EMF back feed from the motor.

How did you connect the resistor?
If you connected the resistor between the Blue wire from the XPFM and the fans line wire. That was incorrect.
Connect the Blue wire to the fans line connection as you normally would. The resistor has to go from the XPFMs White to XPFMs Blue wire.

Brian, Thanks for the quick replies... please forgive me, but you confused me when you said that the resistor has to go from the XPFM's White to XPFM's Blue.  Those two wires aren't connected.  The white will go to the neutral line in the house.  I can put the resistor on the white wire, but I want to make sure that I'm not misunderstanding you... The white and blue shouldn't be touching... correct?

Update: I put the resistor on the white line from the XPFM and then I lost the ability to turn the fan off at all (press the off button and no click at all - not even click off and click back on like before). I think that disabling local control is really the best option for this setup... I just don't know how :(

oh... it works like a charm... and I unlike the site mentioned earlier in this thread, I was able to make it work with 1 47k 1/2 watt resistor... not 2. (They were correct, Radio Shack doesn't carry the 22k 1 watt resistors).

This shouldn't produce enough heat to prevent me from mounting this in the switch box in the wall... correct?

47K with 120 volts is about .306 watts.
I don't think it will get too hot.
Just have some insulation on the resistor lead to insulate them. Not wanting them to touch anything and spark.  ;D
