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. The password is a combination of different navigation keys.

Power-ON sequence

The Power-ON sequence takes around 6 sec.
In case the optional communication on MODBUS is present, the startup time takes
around 40 sec.
