529t sunroof module

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.
