When the door is open and the press to test button in the MCU is activated. A sequence of events occurs.
All LEDs light momentarily
to indicate self test start
Discovery of CSU and registration into the ATM system
MCU beeps and blinks one green LED for every CSU in system
“BEEP” -> (X number of CSUs)
If self-test passes the MCU beeps one long beep and lights a green led
“BEEEEEEP” ->
If self-test fails the MCU beeps two short beeps and lights the red led
“BEEP” ->
BEEP” ->
Then the fault or error code readout occurs.

Then followed by AREA word, SPACER word, ERROR CODE, then off and then the next code

Press to Test button released
Test in progress (~10 seconds)
BEEP, BEEP two CSUs found
