B The T text field allows user to enter the terminal of this recorder.
ERMINAL
C The T field contains all the thresholds created. The logic equation uses
RIGGER LOGIC
AND and OR logic operators over previously defined thresholds. Initially, all preset
thresholds are displayed as implicit OR operators, one per line.
To enable thresholds individually, click on the threshold and select Enable;
To disable discarded thresholds individually, click on the threshold and select Disable;
To break or remove complex thresholds, click on the threshold and select Cut last;
To create equations with AND operators, follow the procedures below:
Click on the threshold and select Cut last;

 Click on the threshold to which is desired to add the previously selected
threshold and then select the threshold to be added.
D Selecting the R
ECEIVE
box enables these features. It allows the start of the recording of an exceeded
threshold by Ethernet cross-trigger.
Note:
The maximum number of RA333 that can be connected to the RPV311 is 4.
The RA333 module has to be connected to the RPV311 processing module before its
initianilzaton. Otherwise a log message will tell the user to reboot the device.
In order to register the beginning of the fault's traveling wave it is important to use
instantaneous protections trips (or starts) as digital input for trigger, for example: 50,
21Z1, 67I, 87 etc. In addition, we recommend the following thresholds:
Threshold
Phase Overcurrent
Neutral Overcurrent
Current Negative Sequence
Phase Undervoltage
Neutral Overvoltage
The limits values can be adjusted depending on the needs of each installation using
real events as basis
