Roller Shutter door connections?

hursty · Jan 27, 2015

Hi
I have been called to a job recently to install a up and down switch for a small roller shutter door. Motor and control unit all there but previous owner had ripped the switch out.
So just left with a few cables not connected to anything and empty connections.

I havent done a roller door like this only a garage door. But what im just asking is the actual connections for the wires. I have labelled connections L, N, (motor) - com, Door up and down, they look like spade type connections, but they arent, as they are a thin bit of metal with a hole in, almost looks like some connector slots down onto them?

If anyone could clear this out for me, would be very helpful.

Thanks

Sorry trying to figure how to upload a picture on here, anyone know?

Is it single or three phase? Are there infrared beams or similar to stop the door if obstructed? Are there limit switches?

It may be that the safety interlocks are installed or not required in this instance, but if you've not done one before, I'd call in a specialist.

So many of these on the market that without any info its anyones guess... best get a person in competent in roller shutter systems, the weight of responsibility you would have on your shoulders if you mess with this is pretty big so as its clear your out of your comfort zone I would suggest to leave well alone, a working roller shutter does not mean a safe one, so even if your get it going you could have created a death trap.

Yes that's the sort of opinion I was thinking and just leaving job alone. As I have no info on the unit and just from a quick talk to customer, there are no signs of limiters or photocell sensor. First thought was to you a rocker release switch which then the motor can only move with a finger on a button. But due to the mess in the unit I'm in two minds.
Or maybe just suggest a handheld drill on the Manual pole.

by way it is a single phase. Any ideas on the connections just to know?

Again without any make and model you are asking us to knit soap here .....too many variants to give a response so on this occasion second guessing can be a dangerous thing.

Good advice. These things can seriously hurt people. I would not do it if I were you. Get a specialist, chuck on 10%. Done!

Just meant with no real information the request for us to help was going to be impossible to do... made it up tbh, might have worked better if I added bubbles on the end of it.
Just my weird way of thinking :juggle2:

You mean like plaiting s*** ?

Plaiting fog is easier than knitting soap.

I justhope the OP abandons this job.

I take it that this is the open and close switch?
With single phase, these are often wired with a live feed, and 2 switched lives.
1 switched live for open, the other for close.

Leave well alone, if you reinstate the doors and there are no safeties fitted and someone gets hurt,
you will be liable as the person who reinstated.
It may have been disabled for a reason.

The majority of roller shutters and garage doors do not have safety devices.
The motors are so low powered, and the weight of the doors is such that there are requirements for safety devices.
From the information contained in the OP, it is unlikely that there is a requirement for safety devices to be fitted.

Roller shutters that have a wicket door will need a switch to allow the main door to only be opened when the wicket door is fully open.

That would be 'wicket' door.
It could be that a switch would be required, again it would depend on the size and type of the motor.
The OP States that this is a small roller shutter, as such, it is unlikely that there is a wicket door, if there is, it also unlikely that such a switch would be required.

That is what I put.... ;-)

Those doors are wicked though. I really like them.

Sorry, read it as 'wicker'.

I am no expert. There was an incident on a job near us where these switches were not fitted and as such the wicket door was allowed to go up with the main roller shutter. Obviously not right. The wicket door came off it's hinges and hit the bloke on the shoulder. How he was not seriously injured or killed is beyond me. During the investigation the lack of these safety switches was put down as the cause. I am unsure whether there was a prosecution.

If it moves and can injure persons, there must be safeties or fail safes in place to prevent movement.

Not going to go into the variations where safety switches are required at this time, I have to go out.
However common sense should be all that is required to work out when safety switches would or would not be required.
