Hey everyone, just want to preface my post by saying that I'm not knowledgeable/trained on machine safety in any way, but I'm installing some PF525s in place of some older AB drives on a boiler coal feeder system. Some of the plant guys brought up the idea of utilizing the Safe Torque Off function using an E-stop button just for peace of mind during for the mechanics during maintenance, but they also don't want the E-stop mounted on the outside of the enclosure because an accidental stoppage of a drive would trip the boiler. Would it be kosher to mount the E-stop button inside the enclosure so that when the boiler and coal feeders were down for maintenance, they could open the enclosure and hit the button and know that the drive/motor is in a safe state? I could see there being issues around a couple of things, namely using an E-stop button in a non E-stop manner, and mounting the actuator to a safety input inside a cabinet. Just wanted to run it by people who are more experienced with this side of things, I would rather not put the plant in violation of safety standards which they would then have to stop the operation of the boiler to rectify.
EDIT: There are currently no E-stops mounted on the outside of the drive enclosures.
Thanks!
