c) CSU self-test
The MCU will cause the CSU to self-test all sensors and inputs. After completion if no errors
are found the CSU will beep once to indicate no faults. If an error exists the CSU will beep 2
times to indicate a fault condition. Further it will report this error to the MCU for BIST code
readout.
d) MCU self-test
The MCU will do an internal self test to determine if errors or faults exist.
e) Fault/error indication
If no errors or fault conditions are found the MCU will beep 1 time and flash the green LED 1
time to indicate good self-test.
If there are any faults or errors which cause BIST errors in the systems both CSU and MCU the
MCU will beep two times and flash the red led 2 times to indicate self-test failure.
BIST error readout:
If during a STANDBY mode self-test a failure occurs which has a BIST error associated with it, each
error will be readout individually using the LEDs to display the errors. The errors will be displayed in
one second intervals until all errors have been shown. See Table 4 below which shoes which errors cause
BIST codes for each Level of the Octopus ATM Defense System. Appendix A should be referenced to
decode and troubleshoot any BIST error code.
