529t sunroof module

One 529t can not work the windows up/down AND a sunroof open/close by itself. So there is probably a 529t being used for the sunroof, and perhaps a 529t, 530t or other used for the windows.

Have the installer check if the 529t for the sunroof is properly set up for "controlled-duration" operation. Seems it is set for "full-travel" operation.

Sorry for the delay in answering..but I already answered it in a sense.

Use a 530T for the sunroof as well. The only "bad" side effect I can see from this is if it starts raining..other then that the module electrically does the same thing the switch does..in other words the motor itself can not tell the difference if you are using the switch in the car or doing by remote control.

Hope that helped.

No, you do not sound like an idiot at all. You just may not understand what is going on with these modules.

If you go back to my original response "Have the installer check if the 529t for the sunroof is properly set up for "controlled-duration" operation. Seems it is set for "full-travel" operation." you should know what your next step is...to approach the installer and see if that has been done. If the installer does not understand this..find another......or........

I suggested the 530T as a second option since we know it does exactly what you want it to with the windows...so I can't think of any reason on this great blue planet why it wouldn't do the same with the sunroof....in other words the module does not know the difference between a sunroof or a window....they both use motors...the reason the sunroof is not doing what you want it to is either installer related..or the model of module you are using (529t) is incapable..it has nothing to do with anything else.

Also note that the sole reason DEI reccomends the 529T for the sunroof is because that is all that is required...it saves you money as the 530 costs more. But it doesn't mean you can't use something else if you are doing something different..like leaving the sunroof open when you arm the alarm. It does not mean you can't use a 530T or any brand or model module you wish...trust me on this one..the alarm simply sends out a low current negative signal to tell the module when to activate...the alarm system itself has no clue what model (or brand for that matter) module it is controlling.

So..if the installer for whatever reason can not get the 529T to do what you want...but can with the 530T...I would go that route...the alarm will not know the difference regardless.

I hope this cleared things up for you...

OK..this is an easy one since I have a 529T right in front of me..manual in hand..however it does not guarantee you will understand it..but here goes...

Under the section titled "operation mode"....The 529t can operate in either controlled-duration or full-travel mode.

Controlled duration operation stops the window (in your case a sunroof) travel manually if desired.

Full-travel mode, once initiated, operates the window (once again in your case..the sunroof) until full travel is reached.

Now I am not sure what was done to get your widows to operate the way you wanted....either the alarm system that is controlling it is programmed to operate the module as such..or the 530T has a way to be programmed to do this. That is why I recommend you talk to the installer.

Now if I was to make an educated guess...there are 2 possible scenerios. One is that only the 530T can do this (I do not have one in stock or I would check this for you..sorry) or that the 529T can do this and it is only a matter of having the installer set the module up..it most likely has to do with which wire from the alarm they used to activate the module.. or it is getting a negative feedback on its activation wire..in which case it can be doide isolated. I would need to speak to the installer or find out how they did the wiring for any more useful info to be given.

Ok..at least we are getting somewhere.

What I need from you is to post the year make and model of the vehicle.

I will also need to read a manual from a 530t..I believe the current limiting shutdown is fully adjustable on those so if going to the motor as it should be..I can't understand for the life of me why the DEI tech said the 530T would keep the motor going ... I need to look into this a little further before advising.

I was able to pull the 530T manual online. Near the end of the manual it states they "recommend" using a 529T but it really doesn't tell why or if it is impossible to use a 530T. Strange because the 529T is also a window module..it is NOT designed specifically for sunroofs.

I still would like to know the type of vehicle since there may be some extenuating circuimstances with that particular sunroof ..but I can't imagine that one window module from another would know the difference.

You might need to find an installer that is a little more adventurous...if you came into my shop I would figure out how to do what you want if it is not a hazard. And since the 529T can operate the sunroof safely...I am still perplexed why DEI would say it can't..well not DEI...just the tech you spoke to who answers phones....he may not be a rocket scientist...lol

I can't imagine there being any problems..however..you might want to ask around a little more..or perhaps another member who has used a 530T on a sunroof can tell us if the motor kept running..but that sounds absurd to me.

Good Luck with it and anymore questions feel free to ask.

I don't think the question should be "why wouldn't the sunroof stop the motor when it senses resistance too?" but rather why wouldn't the 530T stop powering the window motor when it senses more current draw..which would by all common sense in power window module design it should do.

What happens is as physical resistance is placed on the motor..such as when it has reached the end of it's travel..or if an arm is caught in it etc..this causes an increase in current draw...the module senses this and shuts down.

That is the reason why I can see no safety concern in using a 530T for a sunroof..a motor is a motor. I would call DEI myself and ask but fear the same tech will answer.

The good news is you know at least one other member has used a 530T for a sunroof..so regardless if he gets back or not..we know it is possible.

Will do...and I also believe as I stated earlier as well.that the recommendation of the 529T over the 530T was a matter of cost effectivness...not a matter of compatability..In all but your partcular case..a 530T would not be practical and a 529T is all that is needed.

I think because this "tech" read somewhere that a 530T is not nessecary or recommended..it was easier for him to assume it was forbidden to use..rather then getting off his lazy duff and maybe doing a little research for you. Sad..but I have found recently that the tech line there is really becoming a lazy ,unknowing bunch. If they need to move more then a few inches to help you...it's easier for them to say "it can't be done" and take the next call.

I called them myself a few weeks ago about a factory interface and for the life of me I could not get the "tech" to understand that an interface is NOT a bypass module...I got an "I don't know",,,theres your tech line for ya, they used to be better...must be cutting costs in that dept. I guess.

I know..pretty soon we will just be transfered to someone in India reading off a list..oh wait..that happens already..ever call customer service about an XM or Sirius problem???

No matter WHAT you tell them..it's always the installers fault and they say to bring it back to the place that installed ut...but..they are totally lost when I tell them I am the "place" that installed it. Yes..it's sad.

HI creed!

I did reply to your PM, but I will also answer here.  That DEI tech does not know what he is talking about and most probably was reading a script.  Custom audio is correct. A motor is a motor. I have been using the 530T on my sunroof with ZERO problems. I installed it for the same functionality that you wanted...to be able to to hit the sunroof channel button, THEN arm, and still have the sunroof open.  Of course, I only do this in front of my house or when the car is in my plain sight.

Good luck!

Creed,

I don't know what to tell you. I had it in my 1991 Honda Accord for 2 years with no problems. (I yanked it out when I sold the car.)  The sunroof had no tilt function.

I plan on installing the same 530T in my 2003 Chevy Tahoe's sunroof, and I have no worries about doing so.

When using an automated 'window' module with a sunroof you need to make sure you are interfacing directly with the sunroof motor wires, and NOT the switch wires.  Obviously the switch current won't change at all at the end of travel if there is a 'smart' sunroof control module in the car (and most cars have them).

Have you thought about removing the (-) when armed wire from the close trigger and using an AUX output to control when the sunroof closes.  This will give you a bit more flexibility as to when the sunroof closes.  I, personally, would hate for my windows and sunroof to close EVERY time I armed my alarm.  I like to leave my windows vented a bit.  You could hook both the windows and the sunroof up to an AUX channel and have them close only when you push the AUX button.

You would have to hold it, unless you went with either a latching system or a timed relay setup.

DEI alarms have programmable AUX outputs that would output the signal for 30 seconds, that would be perfect for this application.
