Troubleshooting and Maintenance Manual (AADvance
Controller)
A module fault (below)
A fault the controller cannot isolate it to a single module. An example would be
the absence of every I/O module in a termination assembly group.
The System Healthy LED on each processor module will show red.
Module Fault
The controller indicates a module fault when it detects a fault and can isolate it to the hardware of a
particular module. The Healthy LED on the faulty module will show red and the System Healthy LED
on each processor module will also show red.
Channel Fault
The controller indicates a channel fault when it detects a fault and can isolate it to a hardware fault on
a specific channel of a single I/O module. The controller always reports a channel fault as a module
fault as well. This means that the Channel LED will show red, the Healthy LED of the I/O module will
show red and the System Healthy LED on each processor module will also show red.
Field Fault
The AADvance controller indicates a field fault when it detects a fault and can isolate it to a field
condition or a field device. Examples are an open circuit field connection or an out-of-range signal. The
Channel LED on the relevant I/O module will show amber.
