AE-6B SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AE-6B 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.

Note :
· · · All capacitors are in µF unless otherwise noted. pF : µµF 50WV or less are not indicated except for electrolytic types. Indication of resistance, which does not have one for rating electrical power, is as follows. Pitch : 5mm Electrical power rating : 1/4W · · Chip resistors are 1/10W All resistors are in ohms. k = 1000 ohms, M = 1000,000 ohms : nonflammable resistor. : fusible resistor. : internal component. : panel designation or adjustment for repair.
Note : The components identified by shading
and marked are critical for safety. Replace only with the part numbers specified in the parts list.

All variable and adjustable resistors have characteristic curve B, unless otherwise noted. All voltages are in Volts. Readings are taken with a 10Mohm digital mutimeter. Readings are taken with a color bar input signal. Voltage variations may be noted due to normal production tolerences. · · · · · .:+ B s u b : B - bus. : RF signal path. : earth - ground. : earth - chassis.
