AE-6Y Self Diagnostic Software
The identification of errors within the AE-6Y chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In the
event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous
flashing LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant
device number will be displayed through the LED (Series of flashes which must be counted) See table 1, non fatal errors are reported using this
method.
Each time the software detects an error it is stored within the NVM. See Table 2.
