Date Code 20171006 Instruction Manual SEL-400 Series Relays
Instruction Manual
SECTION 12
Settings
This section contains tables of relay settings that are common to most SEL-400
series relays. See the product-specific instruction manuals for details of all set-
tings available in the relay.
The relay hides some settings based upon other settings. If you set an enable set-
ting to OFF, for example, the relay hides all settings associated with that enable
setting. This section does not explain rules for hiding settings; these rules are dis-
cussed in Section 6: Protection Application Examples in the product-specific
instruction manuals, where appropriate.
Isolate the relay trip circuits while
changing settings. When changing set-
tings for multiple classes, it is possible
to be in an intermediate state that will
cause an unexpected trip.
The settings prompts in this section are similar to the ASCII terminal and
ACSELERATOR QuickSet SEL-5030 software prompts. The prompts in this sec-
tion are unabbreviated and show all possible setting options.
This section describes how settings are organized, explains the concept of set-
tings groups, and then describes some common relay settings:

Settings Structure
The settings structure assigns each relay setting to a specific location based on
the setting type. A top-down organization allocates relay settings into these layers:
➤ Class
➤ Instance
➤ Category
➤ Setting
Examine Figure 12.1 to understand the settings structure in a typical SEL-400
series relay. The top layer of the settings structure contains classes and instances.
Class is the primary sort level; all classes have at least one instance, and some
classes have multiple instances. Typical settings classes and related instances are
listed in Table 12.1.
