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-01 sensor relay and simultaneously activate the
binary input BI3 used for over-current condition.
3. Verify that the sensor channel indication LED status is
changed to ON.
4. Verify that the binary input 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.

N
A best practice is to operate circuit breaker at test-
ing. The circuit breaker should open or the contacts
should operate.
6. Verify that the corresponding relay output(s) LED(s) indi-
cation status is changed to ON.
7. If a binary output (BO1, BO2, and BO3) signals are uti-
lized, verify the BO signal activation by status change of
relevant input where binary output signal is connected,
or by measuring the signal output voltage.
8. Verify that the corresponding relay output(s) LED(s) indi-
cation status is changed to ON
9. If the dipswitch No. 8 and No. 7 are both set as light
only mode, activate the camera flash within 20 cm (8
in.) from the EAFR-01 sensor relay and

activate
the binary input used for over-current condition.
10. Verify that no trip has occurred and only the sensor acti-
vation indication LED is ON.
11. Verify that the BOUT signal is activated (if in use and
configured to send light information).
12. Press the SET push-button to reset all indications and
latches.
10.3 Testing the Arc Flash Protection Unit Operation
Time
The EAFR-101 operation time test is not required at com-
missioning as it is performed by Eaton as a type test and
routine production test. Refer to the routine test reports
sent with EAFR-101 relay and consult your nearest Eaton
representative for type test reports.
However, if it is deemed necessary, a site timing test may
be conducted using the following instructions.
1. Use a calibrated relay test set.
2. Connect an output from the relay test set to the cam-
era flash (Metz
®
20B1 or equivalent input) for initializing
the flash and configure a relay test set timer to be
started simultaneously with flash.
3. Connect the EAFR-101 trip output T1, T2, or T3 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-01 or EAFR fiber 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.
