in AC Mode
Deassertion follows the same logic. On the falling edge of IN101R, the
dropout timer starts timing. If IN101R remains deasserted for a period longer
than the dropout timer setting, then Relay Word bit IN101 deasserts to a
logical 0.
Table 4.70 shows the settings prompt, the setting range, and the factory-
default settings for a card in Slot
C
. See the SEL-700G Settings Sheets for a
complete list of the input debounce settings.
Data Reset
The RSTTRGT setting resets the trip output and front-panel
TRIP
LED,
provided that there is no trip condition present. See Figure 4.123 for more
details. The RSTENRGY and RSTMXMN settings reset the Energy and Max/
Min Metering values, respectively. You should assign a contact input (for
example, RSTTRGT := IN401) to each of these settings if you want remote
reset. The RSTDEM and RSTPKDEM settings reset demand and peak-
demand. See Figure 4.121 for the demand current logic diagram.
