3 Operation and configuration
3.1 LED indicator functions
The EAFR-101C contains 16 indication LEDs . A user definable text
pocket can be slid in under the label for identifying each LED func-
tion (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 an 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, the blue power LED is ON, as are any CB
open/close status LED’s for connected CB’s .
The sensor LEDs are off during the inactive condition . 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 and binary input wires or configura-
tion mismatch (new sensor attached without running auto-configu-
ration system setup (see Section 3 .3 .1) situation, the corresponding
LED for that sensor will start flashing and the ERROR LED will
activate .
The Binary I/O LEDs indicate the I/O-line status . If any of the lines
become active for more than 1 .5 ms, the corresponding 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 iden-
tifying the trip information in case the auxiliary power is lost . When
re-powering the relay after power supply loss, the actual LED status
can be visualized from the front of the relay .

connection or system set-up
not performed. Also activated
by pressure information (if L+P
sensors used).
Check why the sensor activated, check
the sensor wire connection, or perform
system set-up (see Section 3.3.1: Auto-
configuration (System setup).

light information.
Sensor channel 3 has loose
connection or system set-up
not performed. Also activated
by pressure information (if L+P
sensors used).
Check why the sensor activated, check
the sensor wire connection, or perform
system set-up (see Section 3.3.1: Auto-
configuration (System setup).
S4 - Amber
Normal status.
Sensor channel 4 activated by
light information
Sensor channel 4 has loose
connection or system set-up
not performed. Also activated
by pressure information (if L+P
sensors used).
