3.5.1 Common Symptoms and Corrective Actions for Field Service Technicians<br />
MESSAGE/ISSUE OCCURRENCE CAUSE SOLUTION<br />
“BDU Communication . . .<br />
FAIL”<br />
Startup test 1 The power supply switch is turned to ON,<br />
immediately after turned to OFF, which<br />
makes the time too short for the BDU control<br />
board power to reboot.<br />
2 The data wire is disconnected or damaged.<br />
3 The BDU control board is defective.<br />
“Software Version . . . FAIL” Startup test 1 Software versions of GUI, BDU and<br />
Keyboard are incompatible.<br />
2 The power supply switch was turned ON,<br />
and OFF quickly.<br />
3 The data wire is disconnected or damaged.<br />
“BDU EEPROM Data . . .<br />
FAIL”<br />
4 The BDU control board is defective.<br />
5 The keyboard board is defective.<br />
Startup test 1 Data stored in EEPROM on BDU control<br />
board is lost (checksum error)<br />
2 The BDU is defective<br />
“EEPROM IC . . . FAIL” Startup test 1 The BDU control board is defective or its<br />
EEPROM is damaged.<br />
“BDU WDT . . . FAIL” Startup test 1 The Watch Dog Timer in the digital signal<br />
