contactors and emergency stop buttons.

[silva.foxx]

... there is a design engineer who has been out to site twice, and he is the one who obviously came up with the install , done the drawings etc. the only drawing i have relating to the pushbutton circuit etc is one showing a 4 pole contactor 32A, withe the four line conductors for the isis machines (sterilisation machines) going through the fore pole connections , and a seperate 6A circuit feeding the pushbutton, which in turn feeds the contactor coil.

Hi Joe

Any chance you can photograph the relevant drawing and post the image here?

With all the varied information that has been given,I may offer a different alternative

It seems to me that the design being used will be intergrating the control circuit for the use of all machines
Press the stop and the lot are off

If thats the case why not use a control distribution panel,wiring in any remote stops in series to each machine to isolate the panel in the event of any stop button operating

You can rcbo what you like,stop buttons scattered around here there and everywhere with emergency stop control over the distribution of all via the panel
You can make up your own with a standard dist board and suitable contactor incomer with a stop and start on the panel


Too many posts to read the whole thread,so forgive me if I have not understood what you are trying to acheive

Joe; how are the machines currently controlled do they not have independant start and stop buttons?
