2.3 List of Fault, Minor Fault, Alarm, and Error Codes
Table 2.2 shows the possible fault, minor fault, alarm, and error codes.
The display codes are in alphabetical order. Search the table for the code shown on the keypad, and identify its causes
and possible solutions.
Note:
The number in parentheses adjacent to the code in the table identifies the fault code or minor fault code (hex. number) that was read during
MEMOBUS/Modbus communications.
Example: AEr (0032)
