Setting the Relay
Overview
Change or view settings with the SET and SHOWSET serial port commands
and the front-panel {SET} pushbutton. Table 9.1 lists the serial port SET
commands.
View settings with the respective serial port SHOWSET commands (SHO,
SHO L, SHO G, SHO R, SHO T, SHO P). See SHO Command (Show/View
Settings) on page 10.25.
In Some Applications,
Make Global Settings
(SET G) First
Make global settings (Global Settings (Serial Port Command SET G and Front
Panel) on page SET.20) before making other relay settings for applications
that require delta-connected PTs, or applications requiring an external zero-
sequence voltage source to be connected to the relay. Changing global settings
PTCONN or VSCONN automatically resets many of the remaining relay
settings to default values. For example, any settings previously entered for the
group settings (SET; SET 1–SET 6), logic settings (SET L; SET L 1–SET L
6), and report settings (SET R) will be lost and will need to be re-entered. The
relay will provide two confirmation prompts prior to accepting a change to
either PTCONN or VSCONN. See Delta-Connected Voltages (Global setting
PTCONN = DELTA) on page 2.14 and Broken-Delta VS Connection (Global
setting VSCONN = 3V0) on page 2.15.
