would anybody have a link 2 a diagram for a roller shutter door including two contactors , mechanical lock and limit switch.

basically a forward revers schimatic

thanks

Is it an electrical interlock your looking for? The diargram above is the mains circuit for forward reverse but you will need a control circuit diagram for the electrical interlock and limit switches. The mechanical interlock is just the little yoke you put between the two contactors

come on mjw hope it out of your notes mate

Theres the control circuit there but it doesnt have the limit switch. The limit switches can just be wired through a n/c in series after each of the push puttons.

Also, on shutters the hold on contact would probably be left out on the downward control, so if the REV button was for shutter down, K2 would be left out so the down button would have to be held in to close the shutter.

A lot of roller shutters are single phase as well, needing just a phase to either the up or down switch wire of the motor.

The control circuit will be the same as above, and the power circuit similar, except one contactor or relay switches on the up feed, and the other the down.

They are simple circuits anyway, once an understanding of exactly what is happening is gained.
