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 restarting.

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 (parameter 16) used as
discrete bits or in DeviceLogix

In the ArmorStart LT web server for ArmorStart EtherNet/IP version

As a sequence of LED flashes on the ECM

MS – Module Status
LED

The bicolor (green/red) LED indicates the
status of the module.
Flashing bicolor (red/green) indicates a
self-test on power up.

Flashing green indicates the device has not
been assigned an IP address.
Steady green indicates the device is
configured and operational.

Flashing red indicates a resettable
protection fault exists or the node address
switches have been changed without a
power cycle and do not match the in-use
configuration.
Steady red indicates a non-resettable
protection fault exists.

I/O Status
Enunciators 0…5
LEDs

Six yellow LEDs are numbered 0…5 and
indicate the status of the input/output
connectors. One LED for each I/O point.

Yellow is illuminated when input is valid or
output is on.

Off when input is not valid or the output is
not turned on.

Reset Button

The blue reset button will cause a
protection fault reset to occur.
