stop circuits

[greengrass66]

Hi all.

just wondering if anybody has any diagrams for stop circuits which are used in school workshops etc. It has been a while since i have wired 1 and feel i need a refresher in this area.

thanks for any help.

Stop in series, start in parallel. Just break the control circuit.

your coil supply comes from it's OCPD then through the stop button to the start button. if there's more than 1 stop on a machine/outlet/whatever, then the stops are wired in series.

Tony's reset must be momentary & key operated though!

unless the stops are key reset ???

Nope, should really be both, however regardless of the stops the energise should be key controlled as I read the standard.

where do you locate the contactor? in room?

where do you locate the contactor? in room?

Wherever is convenient for the staff and not the pupils.

Where would you propose?
