Internal faults

When the Ready LED indicates an internal fault by flashing, the message associated with the fault is
found in the internal event list in the LHMI menu Main menu/Diagnostics/Internal events. The
message includes the date, time, description and signal state for the fault. The internal event list is
not updated dynamically. The list is updated by leaving the Internal events menu and then selecting

Explanation
Non Hitachi Energy vendor SFP detected.
Corresponding hardware(s) is set to fail. Use Hitachi
Energy approved SFP's.
FPGA version is not accepted.
If OEM or NUM FPGA code is of too low version, then
update.
Duplicate IP address detected.
Duplicate IP: <xxxx>
Access Point: <xxxx>
Access Point MAC: <xxxx>
IP duplicator's MAC: <xxxx>
Total: 81.3%
Core0: 64.2 %
Core1: 98.4%
Tips to reduce the CPU load:
• Configure minimum number of functional blocks
• Switch off functional blocks not in use
• Switch off protocols not in use
• Remove IEC 61850 data sets not in use
• Configure minimum communication data points
Check cycle time for SMAI and 3PHSUM blocks
connected to Disturbance Report blocks. SMAI and
3PHSUM blocks shall have the same cycle time.
LDCM transmitter is missing connections. Check the
LDCMTRN block.
System frequency is different in local and remote end of
LDCM link.
Check the parameter FrequencySel at both ends.
LDCM analog latency is different in local and remote.
Check the LDCM parameters AnalogLatency and
remAinLatency at both ends.
HW configuration necessary to configure RSTP on
<Access Point> is missing. Please contact the SA - T
Supportline to fix this error.
Access points can be any of these : AP_1, AP_3
Calculated phase-earth values are used from one or
more SMAIs configured for phase-phase inputs, without
connected N input. However, this configuration,
combined with unbalanced three-phase input, will result
in incorrectly calculated phase-earth values. This in turn
may result in maloperation of functions connected to
SMAIs configured this way, if the function uses phase-
earth based values. Further, if SUM3PH is connected to
such a SMAI, then its output values will be incorrect, and
connected functions may maloperate. To remedy the
situation, please revise the configuration from this
perspective.
