GE L90 Instruction Manual page 160

FRONT PANEL INTERFACE
The L90 supports password entry from a local or remote connection.
Local access is defined as access to settings or commands via the faceplate. This includes both keypad entry and the
RS232 port. Remote access is defined as access to settings or commands via any rear communications port. This includes
both Ethernet and RS485 connections. Any change to the local or remote password enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the L90, the remote password must be used. If the
connection is to the RS232 port of the faceplate, the local password must be used.
There are two user security access levels, setting and command, for which you can set a password for each. Use of a
password for each level controls whether users can enter commands or change settings. Another option is to specify
setting and/or command access for individual user accounts.
• Setting — Allows the user to make any changes to any of the setting values:
– Changing any setting

• Command — Restricts the user from making any settings changes, but allows the user to perform the following
operations:
