TARGET INDICATOR
A target indicator is an optional component selected when a relay is ordered. The electronically latched
and reset target consists of a red LED indicator located on the relay front panel. A latched target is reset
by operating the target reset switch on the front panel. If relay operating power is lost, an illuminated
(latched) target is extinguished. When relay operating power is restored, the previously latched target is
restored to its latched state.
A relay can be equipped with either an internally operated target or current operated target.
Internally Operated Target
The relay trip output is directly applied to drive the target indicator. The indicator is illuminated regardless
of the current level in the trip circuit.
Current Operated Target
A current operated target is triggered by closure of the output contact and the presence of at least 200
milliamperes of current flowing in the trip circuit.
NOTE
Prior to September 2007, BE1-40Q the target indicator consisted of a
magnetically latched, disc indicator. This mechanically latched target indicator
has been replaced by the electronically latched LED target in use today.
