conditions are detected. Protection faults are also known as “trips” or “faults”.
These faults will be reported in multiple formats, including:
• Bit enumeration in the TripStatus parameter 16 in DeviceLogix
• In the ArmorStart LT web server for ArmorStart EtherNet/IP version
• As a sequence of LED flashes on the ECM
