Hi
attached are some pictures of a controller on a machine which we have no info on. I am trying to purchase new or equivelant part.
rough description - its basically an ammeter but will switch of the drive when
the the current reaches its set point,this can be set by
moving the red pointer to a desired setting.


hope you can help

thanks poss31

Who built the machine? What kind of machine is it? How accurate is this cut off? Does the needle operate a pilot circuit when it reaches the red line? i.e. Drop out a contactor?
Where is the machine?
Mark.
