Description of Commands
If you issue the SER CA or SER RA command, the relay prompts, Clear the
sequential events recorder for all ports. Are you sure (Y/N)?
commands. If you answer Y <Enter>, the relay clears all SER records in
nonvolatile memory.
SER CV and SER RV
The SER CV and SER RV commands clear any SER data records that have
been viewed from the present port. The two commands are equivalent.
If you issue the SER CV or SER RV command, the relay prompts as follows:
Clear viewed SER records for this port. Are you sure (Y/N)? If you
answer Y <Enter>, the relay clears all SER records viewed from this port.
The data are still visible to other ports and to file transfer accesses, and they
must be cleared independently for those ports. Data not yet viewed remain
available.
SER D
The SER D command shows a list of SER items that the relay has
automatically removed. These are “chattering” elements. You can
automatically remove chattering SER elements in the SER Chatter Criteria
category of the Report settings; the enable setting is ESERDEL.
If you issue the SER D command and you have not enabled automatic
removal of chattering SER elements (Report setting ESERDEL), the relay
responds,
Automatic removal of chattering SER elements not enabled.
SET
Use the SET command to change relay settings. The relay settings structure is
ordered and contains these items (in structure order): classes, instances,
categories, and settings. An outline of the relay settings structure is as follows:
Classes (Global, Group, Breaker Monitor, Protection, Automation,
Outputs, Front Panel, Report, DNP, and Ports)
Instances (some classes have instances: Group = 1–6; Protection = 1–6;
Automation = 1–10; PORTs = 1–3, F, 5)
Categories (collections of similar settings)
Settings (specific relay settings with values)
The SET and SHOW commands contain these settings structure items, which
you must specify in order from class to instance (if applicable) to setting.
The order that specific settings appear in the relay settings structure is factory
programmed.
