Target Indicators
A gravity-latched, manually-reset, current-operated target indicator is provided for the time-overcurrent
(51) trip output and the instantaneous overcurrent A (50-A) trip output. A target indicator is not provided
for the 50-B trip output. The level of trip circuit current required to operate each target is individually
controlled by a circuit board jumper. See Section 2, Controls and Indicators for jumper locations and
function assignments.
