BE1-51/27C Functional Description
3-5
Internally Operated Targets
Outputs from the overcurrent elements are directly applied to drive the appropriate target indicator. Each
indicator is tripped regardless of the current level of the trip circuit.
Current Operated Targets
This target will operate only when a minimum of 0.2 A flows in the output circuit. A special reed relay in
series with the output contact provides the signal to the target indicator.
Note that the front panel function targets (
TIMED, INST 1,
etc.) may be of either type. Phase and neutral
indicators are current operated only if the instantaneous options are not included and if current operated
targets are specified.
Each target, when operated, is magnetically latched and must be reset manually. Target configurations for
the various models are provided in Section 2.
