TRIGGER ON ANY OPERATE
Range: On, Off
Default: Off
Selection of "On" setting enables triggering of the recorder upon operate state of any of
the enabled protection or control elements.
TRIGGER ON TRIP
Range: On, Off
Default: Off
Selecting the "On" setting enables triggering of the recorder when any of the protection
elements configured as a "Trip" function operates, or the state of the operand assigned
to operate the #1 Trip output relay changes to "high".
TRIGGER ON ALARM
Range: On, Off
Default: Off
Selecting "On" setting enables triggering of the recorder when any of the protection
elements configured as "Alarm", or "Latched Alarm" function operates, or the state of the
operand assigned to trigger the Alarm LED changes to "high".
DIGITAL INPUT 1 to 64
Range: Off, Any FlexLogic operand
Default: Off
ANALOG INPUT 1 to 16
Range: Off, Any FlexLogic analog parameter
Default: Off
The data logger samples and records up to 16 analog parameters at a configured rate. All
data is stored in non-volatile memory, where the information is retained upon a relay
control power loss.
The data logger can be configured with a few channels over a long period of time, or with
larger number of channels for a shorter period of time. The relay automatically partitions
the available memory between the channels in use.
The selection of the rate for logging data also affects the duration of recorded data. The
data logger has longer duration for sampling rates at longer periods of time (i.e. "1 minute",
"30 minutes", "1 hour"), as compared to sampling rates at short periods (i.e. "per cycle", or
"per second").
The recorded data can be downloaded to 8 Series EnerVista program and displayed with
parameters on the vertical axis and time on the horizontal axis.
If data is not available for the entire duration of pre-trigger, the trigger position will be
based on available pre-trigger.

FUNCTION
Range: Disabled, Continuous, Triggered
Default: Continuous
This setting configures the mode in which the data logger operates. When set to
"Continuous", the data logger actively records any configured channels at the rate
defined in the Data Logger Rate setting. The data logger is idle in this mode if no
channels are configured. When set to "Triggered", the data logger begins to record any
