l. Fault 12, EEPROM Corrupt
The O CELL LED flashes four times,
2
pauses for three seconds, and repeats (Fig-
ure 5-12).
1. This alarm can occur if the EEPROM is
changed for a later version. At power
up, the EEPROM is not updated.
2. To correct this problem, power down
and then restore power. The alarm
should clear.
3. If the alarm occurs while the unit is
running, there is a hardware problem
on the microprocessor board.
4. If cycling the power does not clear the
alarm, see paragraph 4-5b, Electronic
Assembly Replacement.
