2.3ACCESS SECURITY FEATURES
MII family relays have several security features to restrict rear port operation when an operator is making changes by the
local port or relay keypad, and/or to block access to setting changes for non-authorized users.
The relay has an access priority system, giving priority to local access over remote access. The access mode is Local
either when the relay display is inside MAIN SETTINGS, ADVANCED SETTINGS or OPERATIONS menu, or when the
front port (RS232) communication is established. When the access is local by the RS232 port, the back port is disabled and
the relay will not serve any petition or command sent by the rear port. When the access is local by keypad, the back port is
not disabled, and actual values can be read, but setting changes and operations will not be allowed by the back port.
Setting changes, either by keypad and display or by communications, are password protected: the user has to enter a
password to change any setting. When the password is entered, the password protection is disabled and the user can
change any setting freely. Thirty minutes after the last setting change performed, or when the ESC/RESET key is pressed
for three seconds or more, the relay returns automatically to the password protected status and will ask for the password
again if a new attempt to change settings is made.
