Troubleshooting and Maintenance Manual (AADvance
Controller)
 The controller was fully operational before the fault arose.
 A serviceable spare module is available.
 There is a working network connection between the computer workstation and
the AADvance controlle.r
Note: You must fit the Program Enable Key (supplied with the T9100 processor base unit) in
order to download application software onto the controller.
Recovery Mode and How it Affects Controller Operation
Recovery Mode
Recovery Mode is a shutdown mode and uses a base level firmware. It is entered automatically when a
critical firmware failure occurs or it can be entered manually by pressing the processor Fault Reset
button immediately after the module has booted up.
As an alternative firmware version it allows the following maintenance activities:
 Update the firmware using the ControlFLASH utility
 Program the processor IP Address with the AADvance Discover utility
 Extract diagnostic information
In Recovery Mode the Ready, Run, Force and Aux LEDs go Amber and the Healthy and System
Healthy LEDs stay Green. The System Healthy and Healthy LEDs may go Red if a fault is detected
while in the Recovery Mode.
Note: When in Recovery Mode the I/O communications are disabled and the Application code is not
running.
Internal Diagnostics
The AADvance controller contains comprehensive internal diagnostic systems to identify faults that
develop during operation and raise appropriate alarm and status indications. The diagnostic systems
run automatically and check for system faults associated with the controller, and field faults associated
with field I/O circuits.
Serious problems are reported immediately, but faults on non-essential items are filtered to avoid
spurious alarms. The diagnostic systems monitor such non-essential items only periodically, and need a
number of occurrences of a potential fault before reporting it as a problem.
