Table 3: List of event types and related description, continue
When blocking by binary input, And shall
have event for both rising & dropping
BI Blocking ↑
BI Blocking ↓
When breaker open, close or maintenance
position sensed by associated binary input
CB POS CLS ↑
CB POS CLS ↓
CB POS OPN ↑
CB POS OPN ↓
In case unable to read Event from EEPROM,
a message i.e. ”Memory Read Fail” will be
displayed for that particular event
When in test menu, initiate hardware test
When in test menu , initiate binary output test
When in test menu, initiate protection
function test
When binary input is mapped to register
power off situation & power supply to IED
goes OFF.
