10. Click the OK button to apply the change. The serial number is not validated.
The settings file and corresponding secure FlexLogic equations are now locked to the L30 device specified by the serial
number.
A traceability feature for settings files allows the user to quickly determine if the settings in a L30 device have been
changed since the time of installation from a settings file. When a settings file is transferred to a L30 device, the date, time,
and serial number of the L30 are sent back to EnerVista UR Setup and added to the settings file on the local PC. This infor-
mation can be compared with the L30 actual values at any later date to determine if security has been compromised.
The traceability information is only included in the settings file if a complete settings file is either transferred to the L30
device or obtained from the L30 device. Any partial settings transfers by way of drag and drop do not add the traceability
information to the settings file.
