MEASURES, LOGIC STATES AND COUNTERS
— Protections
For each protection threshold, the following data are available:
• Start ON/OFF
• Trip ON/OFF
• Logic block (Block1) ON/OFF
• Selective block (Block2) ON/OFF
• Cold Load Pickup ON/OFF
— Delayed inputs
The binary input states, acquired downstream the delay timers are available:
• IN1-1 ON/OFF
• IN1-2 ON/OFF
• INx-x ON/OFF
— Self test
Proper management (programming and remote monitoring) of the self-diagnosis function ensures
the fast detection of most of the protection system failures and significantly reduces the need for
periodic testing.
Following anomalies (MINOR) are not relevant (the protective elements continue to work):
• Oscillography run-time OK/NOTOK
• Data Bus minor OK/NOTOK
• Protection I/O assigned run-time minor OK/NOTOK
• PLC I/O not-matching run-time minor  OK/NOTOK
Lower level diagnostic (MINOR) can be output or ignored; for this purpose the MINORFailalarm
parameter can be set ON or OFF inside the Set \ Self test relay submenu.
All remaining anomalies disables all protective functions
[1]
.
The self test information are:
• Protection and controls ONSERVICE/OUTOFSERVICE
• System diagnostic OK/NOTOK
• Device diagnostic OK/NOTOK
• Program diagnostic OK/NOTOK
• Data-base boot OK/NOTOK
• Data-base runtime OK/NOTOK
• DSP boot OK/NOTOK
• DSP run-time OK/NOTOK
• Memory boot OK/NOTOK
• Memory run-time OK/NOTOK
• Data Bus heavy OK/NOTOK
• PLC boot OK/NOTOK
• PLC run-time OK/NOTOK
• Protection I/O assigned verify startup OK/NOTOK
• Protection I/O assigned verify run-time majorOK/NOTOK
• Total protection I/O assigned not-matching0
• Protection I/O assigned not-matching
• PLC I/O assigned not-matching  OK/NOTOK
• PLC I/O assigned not-matching run-time majorOK/NOTOK
• Total PLC I/O assigned not-matching 0
• PLC I/O assigned not-matching
Note 1 The relays are being switched in rest position (ON if set with Energized logic - OFF if set with De-energized logic)
