Front-Panel Settings (SET F Command)
Figure 4.112 shows the settings for the example, using the SET F command.
Use the > character to move to the next settings category.
Figure 4.113 shows the display when both HV and LV breakers are open (both
IN101 and IN102 deasserted). Figure 4.114 shows the display when the HV
breaker is closed, and the LV breaker is open (IN101 asserted, but IN102 still
deasserted).

Name String, Alias String, and Either Set String or Clear String Only
The following discusses omission of the Clear String; omission of the Set
String gives similar results. Omitting the Clear String causes the relay to only
show display points in the set state, using the SET F command as follows:
When the Relay Word bit IN101 deasserts, the relay removes the complete
line with the omitted Clear String (TRFR 1 HV BRKR). When both breakers
are closed, the relay has the set state information for both HV and LV
breakers, and the relay displays the information as shown in Figure 4.115.
When the HV breaker opens (LV breaker is still closed), the relay removes the
line containing the HV breaker information because the Clear String
