Heres the situation,
there is a little oil pump,motor, resevoir, for a test bench GE 15hp,3ph 440v 1170 rpm motor
the other day it was brought to my attention that when you tried to shut it off it didnt, until one shut off the main 480 safety switch,
so i replaced the start stop combo switch ( the one were internaly you have your jumper from stop to start)
now it does shut off but you have to hold in the stop button for a few seconds.
i didnt like that so i wired in temp. a maintained e-stop button, removed the float and temperature switch, so only thing in the circuit was, e-stop, start stop combo, and the result was after hitting the e-stop you could still count to two onethousand before
the 709 motor starter dropped out.
normal?? i'm used to starters dropping out fast with no control power. this one has me baffeled, any suggestions? thoughts?
