9 Testing
It is recommended that the EAFR-101C relay be tested prior to
substation energizing . Testing is carried out by simulating arc light
to each sensor and verifying the tripping and LED indication . For
arc light simulation, a suitable light source is provided as part of
the Eaton AQS Tester kit . If an AQS Tester is not present, a camera
flash can be used . A Canon Speedlite
®
430EX or equivalent works
well . Check that the light source has fully charged battery(ies) when
testing .
9.1 Carrying out testing in the light only mode
1 .
Check that the dipswitch setting positions are in accordance
to your application.
2 .
Activate the light source close to the EAFR-01 to be used.
3 .
Verify that the corresponding sensor channel indication LED
status is changed to ON.
4 .
Verify the relay output(s) activation(s) by checking the
circuit breaker status or by monitoring trip contact status.
If a circuit breaker is connected to a trip output, the circuit
breaker should open or contacts operate.
ote:
N
A best practice is to operate the circuit breaker during testing .
5 .
Verify that the corresponding relay output(s) LED(s) indica-
tion status is changed to ON.
6 .
If the binary output (BO1) signal is utilized, verify the BO1
signal activation by the status change of the relevant input
where the binary output signal is connected, or by measur-
ing the signal output voltage.
ote:
N
The BO1 signal is a non-latched type .
7 .
If a binary output signal is utilized, verify that the BO1 LED is
illuminated.
8 .
Press the SET push-button to reset all indications and
latches.
9.2 Carrying out testing in light and current mode
1 .
Check that the dipswitch setting positions are in accordance
with your application.
2 .
Activate the light source close to the EAFR-01 to be used and
simultaneously activate the binary input BI5 used for over-
current condition. BI5 activation may be done by supplying
current to a connected EAFR-110PLV (see AQS Tester Manual
IB019011EN).
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 status.
ote:
N
A best practice is to operate circuit breaker at testing . The circuit
breaker should open or the contacts should operate .
6 .
Verify that the corresponding relay output(s) LED(s) indica-
tion status is changed to ON.
7 .
If a binary output (BO1 and BO2) signals are utilized, 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) indica-
tion status is changed to ON
9 .
Press the SET push-button to reset all indications and
latches.
