For example, Trip latch LED17 (Y/N) = Y and LED17 = 81D1T
The RELÉ FREQ. (underfrequency trip) LED illuminates when Relay Word bit 81D1T
is asserted to logical 1 and
a rising-edge of TRIP occurs.
Trip-latched LEDs (e.g., the RELÉ FREQ. [underfrequency trip] LED) remain latched in and
illuminated until one of the following occur:
• Next trip occurs
• TARGET RESET pushbutton is pressed
• Recloser closes [if global setting “Reset trip-latched LEDs when recloser closes
(Y/N)” = Y]
