NG10 - Manual - 04 - 2022
Relays
For every output relay, the output operating state and diagnostic are available (Read\Relays menu):
• K1 State ON/OFF
• K1 Diagnostic OK/NOTOK
• K2 State ON/OFF
• K2 Diagnostic OK/NOTOK
• ......
• K6 State ON/OFF
• K6 Diagnostic OK/NOTOK
Counters
For every element two set of counters are available (Partial counters and Total counters); the partial
counters can be cleared by the user level, while the Total counter reset can be achieved with pass-
word (Session Level 1).
Every partial counter is reset to zero when ten thousand count is passed.
All partial counters can be cleared by means a single command; for this purpose the Reset partial
counters command must be issued (Commands \ Reset submenu).

Self test
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.
Following anomalies (MINOR) are not relevant (the protective elements continue to work):
• Errors concerning the digital fault recorder.
• PLC I/O assigned not-matching run-time.
• Data bus.
• ME Compensation factor
• Mismatching coefficient (
