This section describes how to program the D90
It is recommended that passwords be programmed for each security level and assigned to
specific personnel. There are two user password security access levels: command and
setting.
The command access level restricts the user from making any settings changes, but allows
the user to perform the following operations.
• Operate breakers via the front panel interface.
• Change the state of virtual inputs.
• Clear event records.
• Clear oscillography records.
• Clear fault reports.
• Change the system date and time.
• Clear energy records.
• Operate control pushbuttons.
The setting access level allows the user to make any changes to any of the setting values
and operate in test mode.
The command and setting passwords are not programmed when the device is shipped
from the factory. When a command or setting password is set to null, the password
security feature is disabled.
