Roller Shutter door connections?

[Deleted member 26818]

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.
