Each time the alarm control switch is momentarily pressed, the EMU
initiates the following sequence of actions:
1. The blower LEDs display the first reported hexadecimal fault
code three times in succession.
— The LEDs display the first reported fault code (for the first
time) for 1 second and then turn O
— The LEDs display the first reported fault code (for the second
time) for 1 second and then turn O
— The LEDs display the first reported fault code (for the third
time) for 1 second and then turn O
2. After the first reported fault code is displayed three times, the
LEDs sequence the display to present the next reported fault
code.
3. Steps 1 and 2 repeat for all reported fault codes.
For a detailed explanation of possible fault codes, see Table 3–8. The
numbered corrective actions represent the sequence to follow to
resolve the problem.
