To List Members; I would appreciate guidance on the subject of emergency stop switches (buttons).
When (if every) is an emegency stop switch manditory? Must an emegency stop switch be a hardware only function, or can it operate through the machine's computer and software? Does the emergency stop switch have to turn off power to the machine, or can it just stop the offending action, while leaving power on? What sort of responce time should be expected for an emergency stop switch (2 part question): a) How long (realy how short a time) must the operator hold emergency stop switch in order for it to operate (i.e when I want to hit the button and run, how long to I need to stand there and hold the button before it functins)? b) How long can the machine continue to move/run/function after the switch is pressed? Thank you. J. Sandberg __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
