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.
