SEL-2020 Instruction Manual
SECTION 6: SETTINGS
INTRODUCTION
This section provides detailed information about the commands used to configure and control the
SEL-2020 and explains how you should respond to the SEL-2020 settings prompts. The
SEL-2020 setting sheets are included at the end of Section 6: Settings.
SET COMMANDS
There are seven SET command variations used to configure and control the SEL-2020’s
operation. These commands correspond to the seven different classes of settings shown in
Figure 6.1 and listed in Table 6.1, namely SET P, SET A, SET U, SET M, SET L, SET G, and
SET C. Figure 6.1 shows how the SET commands relate to specific ports. Table 6.1 lists the
SET commands: their parameters, formats, and uses. Table 6.2 lists the user-friendly editing
keys used with all SET commands.
The SET command always requires a class parameter (P, A, U, M, L, G, or C). If the setting is
port specific, the class is P, A, M, L, or U, and you must supply the port position (1 through 16 or
F). You can give these parameters in any order, for example, SET 1 A or SET A 1. You may
also specify the setting to start with, i.e., SET 1 A ISSUE1, to jump directly to that setting.
Basic, but intelligent, port switching capabilities of the SEL-2020 are established with the SET P
command. You apply the SEL-2020’s advanced communication, control, and database features
with the SET A, SET U, SET M, SET L, and SET G commands. The settings classes used in this
section, and how they apply, are outlined below.
