Two levels of password security are provided: Command and Setting. Operations under password supervision are:
• COMMAND: operating the breakers via faceplate keypad, changing the state of virtual inputs, clearing the event
records, clearing the oscillography records, clearing fault reports, changing the date and time, clearing
the breaker arcing current, clearing the data logger, user-programmable pushbuttons
• SETTING: changing any setting, test mode operation
The Command and Setting passwords are defaulted to "Null" when the relay is shipped from the factory. When a password
is set to "Null", the password security feature is disabled.
Programming a password code is required to enable each access level. A password consists of 1 to 10 numerical charac-
ters. When a

revert to the "Restricted" level.

programmed with event logs and/or targets enabled.
