Instructions for the FP-6000 Protective Relay
4.7 LEDs
The LEDs are used to indicate a number of functions, operations,
and/or warnings of the FP-6000. Please refer to Figure 8 for each
LED location.
Operational LED
The Operational LED is a green flashing LED that flashes for a
one second period, 50% duty cycle. It indicates that the FP-6000
is operational.
Breaker Closed LED
The red Breaker Closed LED indicates that the circuit breaker is
closed based on the state of the 52a and 52b inputs.
Breaker Open LED
The green Breaker Open LED indicates that the circuit breaker is
open based on the state of the 52a and 52b inputs.
Phase Trip LED
The red Phase Trip LED indicates that a phase overcurrent trip
condition has occurred if the 50P-1, 50P-2, or 51P protective
functions operate.
Ground Trip LED
The red Ground Trip LED indicates that a ground overcurrent trip
condition has occurred if the 50X-1, 50X-2, 50R-1, 50R-2, 51X, or
51R protective functions operate.
Other Trip LED
The red Other Trip LED indicates that a trip condition other than
phase or ground overcurrent has occurred. It is linked to the
programmable LED 8.
Alarm LED
The red Alarm LED indicates that an alarm condition has
occurred as programmed in the alarm indicator.
Pickup LED
The yellow Pickup LED indicates the presence of a pickup
condition as programmed in the pickup indicator.
Programmable LED 1 to 8
The function of the programmable LED are user defined. The
logic functions may be used to control the state of these LEDs,
which are based on the states of the inputs programmed for
these LED outputs.
Test LED
The red test LED at the right upper corner of the “Test”
pushbutton indicates that the relay is in the test mode. The test
LED flashes while a fault simulation is in progress. The test LED
shares the programmable LED 7.
Trip Indicator Battery Test LED
A green Test LED is located under the bottom right front panel
cover door. It is above the trip indicating battery (see
Section 4.5).
