Machinery and OEM designers know that building safety into their equipment is a fundamental requirement. To ensure a consistent approach, the ISO 13849 standard provides guidance for machinery control systems that are applied to provide safety functions for machinery.
Safety circuits used in machine guarding applications incorporate devices such as sensors and relays to de-energize equipment if any hazardous condition is detected. These conditions normally involve a machine guard not being closed, a presence sensor detecting personnel in an unsafe area or the triggering of an emergency stop function.
