Automatic Messages
The device displays automatic messages (type of latest failure) when detecting
any failure (see Section 10: Testing and Troubleshooting).
Display Points
Configure the digital (Boolean) and analog information you want to view on the
2x16 LCD screen by setting Display Points. Although the LCD displays a maxi-
mum of 16 characters at a time, you can enter up to 60 valid characters. For text
exceeding 16 characters, the LCD displays the first 16 characters, then scrolls
through the remaining text.
When your SEL-2414 arrives, two display points are already configured with
defaults, the results of these defaults are shown in Figure 8.2.
Boolean Display Point
Boolean information is the status of Device Word bits (see Appendix H: Device
Word Bits). Create a Boolean Display Point with
ACSELERATOR QuickSet
®
SEL-5030 Software as shown in Figure 8.3 or the SET F command. In general,
the SET F syntax for Boolean display points consists of the following four fields
or strings, separated by commas:
Device Word Bit Name, “Alias”, “Set String”, “Clear String”
Examples using the settings in Table 8.1 are shown in Figure 8.4 and Figure 8.5.

NOTE: Valid string characters are
