ACCESS SUPERVISION
The following access supervision settings are available.
• INVALID ATTEMPTS BEFORE LOCKOUT : This setting specifies the number of times an incorrect password can be
entered within a three-minute time span before lockout occurs. When lockout occurs, the
LOCAL ACCESS DENIED
and
REMOTE ACCESS DENIED
FlexLogic™ operands are set to “On”. These operands are returned to the “Off” state upon
expiration of the lockout.
• PASSWORD LOCKOUT DURATION : This setting specifies the time that the F35 will lockout password access after
the number of invalid password entries specified by the
INVALID ATTEMPS BEFORE LOCKOUT
setting has occurred.
The F35 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.
The
UNAUTHORIZED ACCESS
operand is reset with the
COMMANDS
ÖØ
CLEAR RECORDS
ÖØ
RESET UNAUTHORIZED
ALARMS
command. Therefore, to apply this feature with security, the command level should be password-protected. The
operand does not generate events or targets.
If events or targets are required, the
UNAUTHORIZED ACCESS
operand can be assigned to a digital element programmed
with event logs or targets enabled.
The access level timeout settings are shown below.
