3.1 LED Indicator Functions

TThe EAFR-101 contains 11 indication LEDs. A user defin-
able text pocket can be slid in under the label for identifying
each LED function (except Power and Error LEDs). LEDs
are located at the front plate of the relay for clear viewing
without a need for opening doors.
During power up, the relay performs a LED test. All LEDs
are turned on for two seconds and then off. Only the blue
Power LED will remain ON. After powered up, the relay
goes into protection mode in 50 ms even while the LED
test is being performed. During normal operation only the
blue power LED is ON.
The point sensor LEDs are off during the inactive condi-
tion. If a point arc sensor is activated, the corresponding
sensor channel LED will turn on if the activation is longer
than 1.5 ms. The sensor LED activation function is latched
(steady light). To clear the LED, the "Set" button should be
pressed.

In case of a loose sensor wire or configuration mismatch
(new sensor attached without running auto-configuration
system setup [see Section 3.3.1) situation, the correspond-
ing LED for that point sensor will start flashing and the Error
LED will activate.
The Binary I/O LEDs are indicating the I/O-line status. If any
of the lines become active for more than 1.5 ms, the corre-
sponding LED will turn on (latch).
In a trip situation, the corresponding trip LED will turn on.
Trip outputs are controlled by the dipswitch settings (see
Section 3.5).
All activation and trip indication LEDs are latched, even if the
dipswitch setting is in the non-latched mode. They have to
be cleared by pushing the "Set" button.
LED indications are stored in non-volatile EPROM memory
for identifying the trip information in case the auxiliary
power is lost. When re-powering the relay after power sup-
ply loss, the actual LED status can be visualized from the
front of the relay.
Action if Abnormal
Check the power source.
Verify system condition. See Sections 11:
Troubleshooting Guide and 5: System Self-
supervision.
Check the reason for trip. Clear the fault and
reset indications by pushing SET button.
