scope of application
Emergency stop chaining
Jam protection collars
Installed in housing
Emergency-stop-button with self monitoring contactors
To uphold safety, the emergency-stop-buttons' switching elements are equiped with safety contacts. These are constantly supervising the proper connection between the emergency-stop-button and the contact elements. Even redundant, safe emergency-stop-chains are ineffective, if the contactor isn't flawlessly connected to the emergency-stop-button. If, through careless montage or mechanical damage, the emergency-stop-button is disconnected from the contact element, the safety contact will interrupt and stop the machine. After correcting the flaw, the machine can be started again.
