DATA LOGGER
The data logger samples and records up to 16 analog parameters at a user-defined sampling rate. This recorded data may
be downloaded to EnerVista UR Setup and displayed with
parameters on the vertical axis and time on the horizontal axis.
All data is stored in non-volatile memory, meaning that the information is retained when power to the relay is lost.
For a fixed sampling rate, the data logger can be configured with a few channels over a long period or a larger number of
channels for a shorter period. The relay automatically partitions the available memory between the channels in use. Exam-
ple storage capacities for a system frequency of 60 Hz are shown in the following table.
Changing any setting affecting data logger operation will clear any data that is currently in the log.
• DATA LOGGER MODE : This setting configures the mode in which the data logger will operate. When set to “Continu-
ous”, the data logger will actively record any configured channels at the rate as defined by the
