<27> Auxiliary input 1
<28> Auxiliary input 2
<29> Auxiliary input 3
<30> Auxiliary input 4
Note <27>...<30>: Depending on Binary I/O options and application usage there may be additional
auxiliary inputs available in the IED. As default, all "raw" binary input data are mapped to private data.
It is possible for user to re-map these additional inputs into standard <27>...<30> 'Auxiliary Inputs', if
wanted.
3.3.3.3 Supervision indications in monitor direction
INF Semantics
<32> Measurand supervision I
<33> Measurand supervision V
<35> Phase sequence supervision
⊠ <36> Trip circuit supervision
<37> I>> back-up operation
<38> VT fuse failure
<39> Teleprotection disturbed
<46> Group warning
<47> Group alarm
Note <32>, <33> and <38>: IED current and voltage measurement supervision signals and alarms
are found in private data definitions. Semantics of these signals are more complex in this IED series
than what is defined by the IEC 60870-5-103 standard.
3.3.3.4 Earth fault indications in monitor direction
INF Semantics
<48> Earth fault L
1
<49> Earth fault L
2
<50> Earth fault L
3
<51> Earth fault forward, for example line
<52> Earth fault reverse, for example busbar
Note: In this IED series there exist different functions (and signals) for non-directional or directional
earth fault protection. Function- and stage-dependent start/pickup signals are found in private data
locations.
3.3.3.5 Fault indications in monitor direction
INF Semantics
<64> Start /pick-up L

<65> Start /pick-up L
