5-26 L90 LINE CURRENT DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL
PRODUCT SETUP CHAPTER 5: SETTINGS

Pushbuttons (both user-control buttons and user-programmable buttons) located on the front panel can be pressed by an
Administrator or Engineer role. This also applies to the
RESET button, which resets targets, where targets are errors
displayed on the front panel or the Targets panel of the EnerVista software. The RESET button has special behavior in that it
allows these two roles to press it even when they are logged in through the RS232 port and not through the front panel.
To reset the security event log and self-test operands:
1. Log in as Supervisor (if the role is enabled) or Administrator (if the Supervisor role is disabled) and execute a clear
security command under Commands > Security > Clear Security.
Security events
The security events produced when the CyberSentry option is purchased are sent as sytem log (syslog) messages to a
syslog server, if one is configured. The format is as follows.
Event Number — Event identification number (index)
Date & Timestamp — UTC date and time
Username — 255 chars maximum, but in the security log it is truncated to 20 characters
IP address — Device IP address
Role — 16 bit unsigned, of type format F617
Activity Value — 16 bit unsigned
If "System Integrity Recovery" events are logged during a restart of the unit due to an incorrect shutdown sequence,
upgrade the firmware to version 7.31 or later to correct this issue.
