EM and EMD Fault Codes
Table 12 - EM and EMD Relay Nonrecoverable Fault Codes
Fault Code
Decimal (Hex) Description Recommended Action
00 (00) No fault No action necessary.
01 (01) RAM test
Follow the general instructions for faults. See General Instructions for Faults on page 39 .
02 (02) Stack over-/under-flow
03 (03) Configuration mismatch between
Processors A and B
04 (04) Internal timing
05 (05) EEPROM read/write failure

settings (switch 2: Time) and setting
stored during power-up.
09 (09) SPI compare fault
Follow the general instructions for faults. See General Instructions for Faults on page 39 .
