10.2 Carrying Out Testing in Light and Current Mode
1. Check that the dipswitch setting positions are in accor-
dance with your application.
2. Activate the camera flash within 20 cm (8 in.) of the
EAFR-06/07/08 fiber loop sensor unit and simultane-
ously activate the binary input BI1 used for over-current
condition.
3. Verify that the sensor channel indication LED status is
changed to ON.
4. Verify that the binary input BI1 indication LED status is
changed to ON.
5. Verify the relay output(s) activation(s) by checking the
circuit breaker status or by monitoring trip contact sta-
tus.
otee:
N
A best practice is to operate circuit breaker at test-
ing. The circuit breaker should open or contacts
operate.
6. Verify that the corresponding relay output(s) LED(s) indi-
cation status is changed to ON.
7. If the binary output (BO1) signal is utilized, verify the
BO1 signal activation by the status change of the rele-
vant input where the binary output signal is connected,
or by measuring the signal output voltage.
8. If the binary output signal is utilized, verify that BO1
LED is illuminated.
otee:
N
The BO1 signal is a non-latched type.
9. If another binary input BI2 is in use, verify correct oper-
ation by activating the input.
10. Activate the camera flash within 20 cm (8 in.) from the
EAFR-06/07/08 fiber loop sensor unit and do not acti-
vate the binary input BI1 used for over-current condi-
tion.
11. Verify that no trip has occurred and only the sensor acti-
vation indication LED is ON.
12. Verify that the BOUT signal is activated (if in use and
configured to send light information).
13. Press the SET push-button to reset all indications and
latches.
14. If the binary input BI2 is utilized for master trip to acti-
vate the BI2, verify that a trip has occurred by repeating
Steps 4 and 5.
15. Press the SET push-button to reset all indications and
latches.
16. Repeat the testing procedure for all sensors.
10.3 Testing the CBFP Function
The circuit breaker failure function is tested by leaving light
signal and second trip criteria signal (e.g. over-current), if
applicable, active for above the set CBFP time of either 100
or 150 ms. The trip relay T2 and binary output BO1 should
be active after the set time delay.
10.4 Testing the Arc Flash Protection Unit Operation
Time
The EAFR-102 operation time test is not required at com-
missioning as it is performed by the manufacturer as a
type test and routine production test. Refer to routine test
reports sent with the EAFR-102 unit and consult your near-
est Eaton representative for type test reports.
However, if it is deemed necessary, a site timing test may
be conducted using the instructions that follow.
1. Use a calibrated relay test set.
2. Connect an output from the relay test set to the cam-
era flash (type Canon Speedlite 430EX or equivalent)
input for initializing the flash and configure a relay test
set timer to be started simultaneously with flash.
3. Connect the EAFR-102 trip output T1, T2, T3, or T4 to
the relay test set input and configure the input to stop
the timer.
4. Place camera flash to a maximum 20 cm (8 in.) dis-
tance of the EAFR-06/07/08 fiber loop sensor.
5. Initiate the flash and timer using the relay test set out-
put.
6. Read the measured time between simulated arc and
trip contact operation.
7. Subtract the digital input delay of the relay test set
from the final measured time if applicable. For specific
test instructions consult the manufacturer of the relay
test set.
