Xpelair fan wiring.

[batty]

I am installing an Xpelair BX turbo fan supplied by customer. Xpelair BriteX BX100+W Turbo Fan and White Light Kit [91248AW]. Now the instructions with fan says it only has three connections but it has a four terminal block. If you look closely on the fan body it say T L1 L2 and N. Now I would assume the T is for switch live and N is for neutral not sure where permanent live should go. They did also have another book with fan but somebody has tidied it away and it can't be found. I have tried there technical and they were no help also tried permanent live on L1 and L2 but it just runs on and on has anybody wired one of these fans up and knows which way cables go round.

Don't these fans need a controller?

I pressume T is perm and L1 is switched, L2 could be for reverse?

 

[batty]

Don't think so they are a bathroom fan.

Does this help in any way

Could the T be anything to do with the timer? the switched Line perhaps?

No Manator as said if you look at the drawing it only has three connections and the fan actually has a four terminal block. One isn't for the cpc as they are all coloured cables coming out of the back of it. The technical guy said it only has three connections also he really wasn't a help but he did say that the terminal block is marked but the markings are actually embossed on the fan body T L1 L2 and N.

 

[Manator]

According to the wiring diagram T is the switched line and L is the perm.

Id say it was a controlled fan and can either be reversed or speed controlled,

thats normally T and L2 does that.

 

[batty]

Are you sure steps this is an inline fan with showerlight unusual to have air coming into bathroom.

 

[steptoe]

perhaps simply speed controlled then,

maybe just a generic moulding,?

without destructions you are going to have to start belling out/trying different combinations,

the point being, I have never come across T in a fan before that wasnt designed to be used without a controller, not saying it needs one, just that it has the capability of using one.

ah, just clicked your link,

I think I have it now, you have a constant trickle feed fan with a turbo and over-run timer,

what that means is, your fan constantly runs at a slow speed, when the light is turned on it runs faster, when the light is turned off it runs at the fast speed for a preset time, then returns to its trickle speed once again.

you do indeed have a constant flow fan, similar to enviro-vent as fitted by loads of social housing authorities.

Not sure thats what they want, don't you hate it when customers buy there own stuff. I generally fit a manrose CFD fan with manrose showerlight now I do know how to wire them up.

 

[steptoe]

you can usually bypass this by simply linking the trickle feed to the switched live, then the over-run to perm live.

it would depend on if the fan works on a trigger switched live or it needs it all the time.

customers buying their own stuff, headbang

I think I may give that a go steps trouble is as I am not sure which is which it will have to be a bit of juggling about as long as I don't put a L to the neutral I should be ok.

 

[steptoe]

batty, figure out your N first, then do something that shouldnt ever be done,.

have the fan reworked to used a 9v battery, then when the - is connected see what terminal you need + connected to to

A get the fan to just run

B get an over-run

you may need to link out a terminal I think by the looks of things.

 

[batty]

That don't make it easy the embossed letters are the same colour as the fan so you can't read them easily well I can't. The terminal that is neutral has a red cable coming out of it one of the other terminals has a blue cable coming out of it to me that is wrong.

 

[steptoe]

:slap

welcome to the world of who cares less, someone else is installing it.......

 

[Manator]

I think one of the terminals for line is a variable speed, and the other for a fixed speed. If using a controller then the variable speed connection would be used. I have fitted the larger models of these but have no idea what the wiring arrangements were, its been that long ago.

IIRC a lot of Xpelair fans are two speed, you may need a speed controler
