5.2.1 PASSWORD SECURITY
PATH: SETTINGS PRODUCT SETUP PASSWORD SECURITY
Two levels of password security are provided:
Command
and
Setting
. The following command operations are under pass-
word supervision:
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 amps, clearing
energy records, clearing the data logger, user-programmable pushbuttons
The following setting operations are under password supervision:
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 one to ten numerical char-
acters. When a
CHANGE ... PASSWORD
setting is set to “Yes”, the following message sequence is invoked:
1.
ENTER NEW PASSWORD: ____________
2.
VERIFY NEW PASSWORD: ____________
3.
NEW PASSWORD HAS BEEN STORED
To gain write access to a "Restricted" setting, set
ACCESS LEVEL
to "Setting" and then change the setting, or attempt to
change the setting and follow the prompt to enter the programmed password. If the password is correctly entered, access
will be allowed. If no keys are pressed for longer than 30 minutes or control power is cycled, accessibility will automatically
revert to the "Restricted" level.
If an entered password is lost (or forgotten), consult the factory with the corresponding
ENCRYPTED PASSWORD
.
In the event that an incorrect Command or Setting password has been entered via the faceplate interface three times within
a three-minute time span, the
LOCAL ACCESS DENIED
FlexLogic™ operand will be set to “On” and the L60 will not allow
Settings or Command access via the faceplate interface for the next ten minutes. The
TOO MANY ATTEMPTS – BLOCKED
FOR 10 MIN!
flash message will appear upon activation of the ten minute timeout or any other time a user attempts any
change to the defined tier during the ten minute timeout. The
LOCAL ACCESS DENIED
FlexLogic™ operand will be set to
“Off” after the expiration of the ten-minute timeout.
In the event that an incorrect Command or Setting password has been entered via the any external communications inter-
face three times within a three-minute time span, the
REMOTE ACCESS DENIED
FlexLogic™ operand will be set to “On” and
the L60 will not allow Settings or Command access via the any external communications interface for the next ten minutes.
The
REMOTE ACCESS DENIED
FlexLogic™ operand will be set to “Off” after the expiration of the ten-minute timeout.
The L60 provides a means to raise an alarm upon failed password entry. Should password verification fail while accessing
a password-protected level of the relay (either settings or commands), the
UNAUTHORIZED ACCESS
FlexLogic™ operand is
asserted. The operand can be programmed to raise an alarm via contact outputs or communications. This feature can be
used to protect against both unauthorized and accidental access attempts.
