1.1 Information on the local HMI
If an internal fault has occurred, the local HMI displays information under:
Diagnostics\IED status\General
Under the Diagnostics menus, indications of a possible internal failure (serious fault) or internal
warning (minor problem) are listed.
Indications regarding the faulty unit are outlined in table 23 .
Table 23: Self-supervision signals in the built-in HMI
HMI Signal Name: Status Description
INT Fail OFF / ON This signal will be active if one or more of
the following internal signals are active;
INT--NUMFAIL, INT--LMDERROR,
INT--WATCHDOG, INT--APPERROR,
INT--RTEERROR, INT--FTFERROR, or
any of the HW dependent signals
INT Warning OFF / ON This signal will be active if one or more of
the following internal signals are active;
INT--RTCERROR,
INT--IEC61850ERROR, INT--TIMESYN-
CHERROR
NUM Fail OFF / ON This signal will be active if one or more of
the following internal signals are active;
INT--WATCHDOG, INT--APPERROR,
INT--RTEERROR, INT--FTFERROR
NUM Warning OFF / ON This signal will be active if one or more of
the following internal signals are active;
INT--RTCERROR, INT--IEC61850ERROR
ADMnn READY / FAIL Analogue input module n failed. Signal
activation will reset the IED
BIMnn READY / FAIL BIM error. Binary input module Error sta-
tus. Signal activation will reset the IED
BOMn READY / FAIL BOM error. Binary output module Error
status.
IOMn READY / FAIL IOM-error. Input/Output Module Error sta-
tus.
MIMn READY / FAIL mA input module MIM1 failed. Signal acti-
vation will reset the IED
RTC READY / FAIL This signal will be active when there is a
hardware error with the real time clock.
Time Sync READY / FAIL This signal will be active when the source
of the time synchronization is lost, or when
the time system has to make a time reset.
