KV-25F3
The identification of errors within the BE-3D chassis is triggered in 1 of 2 ways :- 1: Bus 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 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 with this method.
