Roller shutter problem

[Sid1968]

I hope this is the correct place to post

I have a external electric roller shutter. it was working fin until last week my son accidentally gently reversed in to the shutter whilst it was opening. no visible damage ie bent slats etc

Now it does not fully open stops 2 ft from fully opened. iv tried forced pushing it whilst opening still stops 2ft from fully open.

What i have noticed when fully closed the slats looking at the roller box the slats are at a angle not level to the roller box if that makes sense. one end is higher that the other i dont know if that is the problem causing not to opening fully.

I have took the roller box off drilled the rivets. the bar of the shutter are going into side runners with a bolt. I was thinking of undoing the bolt from one side and manually rolling the shutter until the slats are parallel level with the shutter bar rather than being angled

any advice please will be much appreciated

I take it the 'gently reversed, no visible damage' description came from the shoddy driver rather than an unbiased eye witness account?
First and best option- get the offender to put his hand in his pocket and pay for the installers (or a local firm who look after roller shutters) to come and have a look.
Are they steel or aluminium (the slats)?

Lol

It was my son who was reversing probably on his phone at the time

Steel slats

You said it was your son in the 1st post, just a thought that he needs to learn actions have consequences- think of the kittens! Question still stands- did he tell you he'd gently reversed in & no bent slats or did someone else see it?

If the bottom slat is still getting flush to the ground it suggests that one of the slats has come unlinked. Stick a tape measure up each side of the door, see if there's a point where they go from level to not level. Are the slats loose on the low side (ie can you rattle then to and fro in the track)/tight on the high side? Got any pics?

Your best investigation method is usually to remove one of the tracks - that way you can see what's going on more easily. May be a problem if you can't get to the top fixing...

Iv send some photos

When its open and stops if you look at the shutter box and the slats from outside the slats are at a slant compared to the shutter box line. Sonthe shutter box edging is straight and slates at a angle gping in and stops about 2 foot to the end
Hope that makes sense

Hmmmm. Not the best quality photos- try doing some of that side when the sun is on it & then the other side later in the day. Was he reversing in from outside? Looking at your 2nd pic, when the door is 2/3rd closed the slats on the drum look level, while on your 1st pic the drum is all over the place.

You're fortunate its is outside- can you check that the slats are fitted securely to the drum & they're in a straight line at the top (think they will be) when the door is closed. And then get a straight edge and offer it vertically across the whole door then horizontally across each slat- it'll only take a few mm out of straight to get that pileup you're getting, the door is probably stopping short because the righthand side is jamming.

Il send photos from the out side
Then u will kno better

He was reversin out

 

[Sid1968]

I might be wrong
If i cn undo the nut from unlevel side and manually roll the shutter up in till level with the shutter box??

 

[oldbutnotdead]

Which bolt- the one on the end of the roller? Don't do that.
The slats on the roller are going unlevel because one or more is bent or twisted, wouldn't have to be by much.

 

[Sid1968]

Please have a lool at the photos from the outside

 

[Sid1968]

Thats where is stops will no open any further

 

[oldbutnotdead]

Ok. Now some pics from the front when its closed.... I'd expect to see 1 or more bent slats at about 600 above ground level. Have you done the straight edge yet?

 

[Sid1968]

Soory for late reply
Please see pics of shutter closed

Hi, apologies for jumping in this question/thread but I've searched everywhere and can't find the answer.

I would like to have an external shutter like yours installed however I have been told electrictrics isn't something they sort out and I would need an electrician.

The will install the shutter however leave the nvr control unit on the wall next to the shutter with a 1.5m cable. My question is, is the NVR unit safe there? Surely its not waterproof and secondly can someone get in to the rear yard and open the shutter by pressing the button. Secondly can I just extend the cable using a junction box (ip68) and plug it to my kitchen? If so how would I protect the wiring outside?

Finally is there anything else I would need to do to protect the electrical part of the installation outside?

I will be getting the electrical part done by an electrician however having prior knowledge when speaking to him will help.

Thank you

I have 2 shutters
One is entrance to the garden with the NVR is inside the utility room.

The 2nd shutter separates car porch and rear yard. NvR is in a waterproof inclosure box side of the shutter.

You can have the Nvr anywhere considering the getting a good signal from the remote fob
