Real Time Clock

IED comes with a real time clock with user settable date and time. Date can be set
in "DD/MM/YY" format and time can be set in "HH:MM:SEC" format. The time
stamping have 1 ms resolution. RTC is used for time stamping the event logs and
as well as fault records . In case of power failure RTC will have a stored energy
backup for around 48 hrs. at ambient temperature when stored energy element is
fully charged. Initial time setting is "01/01/2011" and "00:00:00:000".

Access Control

To protect the relay from unauthorized access and to maintain the integrity of
information, the relay is armed with a three level, role-based user authentication
system with individual password for the operator, engineer (Setting level) and
administrator level. With the Ver. 2.2 FP1 REF601/REJ601 supports two modes
for password handling:
1. a combination of different navigation keys (default mode)
2. alphanumeric password

Power-ON sequence

The Power-ON sequence takes around 6 sec.
In case the optional communication on MODBUS RTU / IEC 60870-5-103 is
present, the startup time takes around 40 sec.
