Fault Diagnostics
Fault diagnostics capabilities built in the ArmorStart LT Distributed Motor
Controller are designed to help you pinpoint a problem for easy troubleshooting
and quick re-starting.
Protection Faults
Protection faults will be generated when potentially dangerous or damaging
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
