4.2 How to operate
DANGER
Test should be performed only after shutting off the electric power and
verifying that there is no voltage present. Failure to do so may result in an
electrical shock.
When current is flowing in the main circuit of breaker, it is combined with the
test signal of Y-2005, consequently does not become correct characteristic.
The operating test should be performed in the state that load current does
not flow in the main circuit.
（1）Set the “Signal level indicator” to
○○○○○.○
by pushing the “Signal level mode switch
TEST SIGNAL(%) / RATIO
“.
（2）Set a signal level in % of Ir by using the “Signal adjusting switches” or “Signal setting keypad”.
●When using the “Signal adjusting switches”:

E-7
5. Test (for AE-SW)
It is possible to display a trip current value on LCD by supplying control power to ETR, if Display (DP1
or DP2) (*option) is equipped. However, this value may become somewhat larger than the value
displayed by Y-2005, especially in case of STD and INST trip. Furthermore, since the test signal from
Y-2005 is not input into the Extension module (EX1), even if it supplies the test current to ETR, the
measuring current value displayed on LCD will be as “0”.
5.1 LTD Pick-up current test
（1）Set the signal level to approximately 90% of LTD pick-up current.
（2）Push
START
switch.
（3）Increase the signal level with “Signal adjusting switch”, and take a reading of pick-up value.
（i）In case of WS type relay
The pick-up value is calculated by;
(Pick-up level at a point where ETR turns a [OVER] LED on)÷Iu.
Example) When the [OVER] LED lights at 94% with Iu=0.8, the pick-up value is 94%÷0.8=117.5%.
（ii）In case of WM type relay
The LTD pick-up level can be taken at a point where ETR turns a [100%] LED on.
（4）Push
STOP
switch.
（5）Push
RESET
switch and start at (1), if testing again.
Increase the signal
level with this 1%
step key.
Signal adjusting switches
5.2 LTD operating time test
（1）Set a desired signal level.
（i）In case of WS type relay
The operating time is to be taken at 200%Iu, therefore, if Iu is set to 1.0, set the signal level to 00200.0 .
In case that Iu is not set to 1.0, for example, if Iu is 0.9, since 0.9×200%=180%, set the signal level to 00180.0
（ii）In case of WM type relay
The operating time is to be taken at 120%IL, therefore, if IL is set to 1.05, since 1.05×120%=126%,
set the signal level to 00126.0 .
.
（2）The Isd (short-time-delay pick-up current) and Ii (instantaneous pick-up current) setting dial of ETR should be set to 1.2 times
or more the above-mentioned signal level.
（3）Push
START
switch.
（4）After tripping, the operating time is indicated.
（5）Push
RESET
switch and start at (3), if testing again.
Since ETR has a memory effect for overcurrent state, when the operating time test is interrupted on
the way, the operating time at the next test becomes short. This memory effect can be reset by
tripping. Therefore, if operating time test is interrupted on the way, perform the next test after tripping
ETR one-time. To trip, perform the trip check in accordance with 5.12.
＜Hint＞ In section 5.1 and 5.2, if Iu of WS type relay is not set to 1.0, the reading value of the signal level can be regarded as
the LTD pick-up current (%) by setting the value of H ○.○○○ to Ir×Iu. Also, when measuring the LTD operating time,
test can be performed with the signal level 00200.0 . However, when checking the STD or INST characteristics, return the
setting of H ○.○○○ to a former value.
E-8
5.3 STD Pick-up current test
（1）Set Ii (instantaneous pick-up current) setting dial of ETR to the maximum,
and set Tsd (short-time-delay operating time) to the minimum (0.06s).
* If the setting value of Tg is large, exact measurement cannot be
performed in the following (5).
Increase the signal
level with this 10%
step key.
（2）Set the signal level to approximately 80% of Isd.
Signal adjusting switches
（3）Push START switch, and immediately increase the signal level with a
10% signal adjusting switch until ETR trips and Time counter LED stops.
Increase the signal level by using 10% step key. Since it takes a long time to test in case of 1% or
0.1% step, the LTD pick-up may operate before STD. If LTD pick-up operates even the 10% step,
start again at approximately 95% of Isd.
（4）Read the signal level indicated at the time.
（5）Furthermore, measure the operating time near the pick-up current measured in (3) by using 1% step key. The point where the
operating time becomes short suddenly serves as accurate measured value of Isd.
（6）Push
RESET
switch and start at (2), if testing again.
5.4 STD operating time test
（1）Set Ii setting dial of ETR to the maximum.
（3）Push

Signal adjusting switches
5.16 PAL2 operating time test (*Only when P3, P4 or P5 module and AP module are equipped)
（1）Supply power to ETR (between
P1
and
P2
of the circuit breaker's control circuit terminal block).
（2）Connect the "Stop signal input" on the back of tester and the contact terminal for PAL2 OUT (between 544 and 513 of
the circuit breaker's control circuit terminal block). Then set the "Stop signal input switch" to [a].
*The terminal allocation for PAL2 OUT ( 544 and 513 ) described in above is the assignment at the factory shipments. If
this allocation is changed by using the display (DP1 or DP2), it differs from the above allocation.
（3）Set a desired signal level (See section 5.2).
（4）Push
START
switch.
（5）After operation, the operating time is indicated.
（6）Push
RESET
switch and start at (3), if testing again.
Since ETR has a memory effect for overcurrent state, when the operating time test is interrupted on
the way, the operating time at the next test becomes short. This memory effect can be reset by
tripping. Therefore, if operating time test is interrupted on the way, perform the next test after tripping
ETR one-time. To trip, perform the trip check in accordance with 5.12.
5.17 OCR alarm switch (AL) check
The OCR alarm switch (AL) is a contact (“a” contact) of short time operation (30-50ms) Note). This time can be measured with the
oscilloscope, the millisecond counter or the like.
Note): In case of the manual reset type (MRE) (*option), AL is output continuously. This contact output is not reset until pushing
the manual reset button of breaker.
Y-2005 enables a check of operation even if breaker is in the state of OFF. However, as for AL
checking, since AL is included in the trip mechanism, AL is output only when tripping from ON state.
(AL cannot be output unless tripping actually).

10. Initial setting and operation (for AE-SS/SH)
Start the setting and operation after carefully reading an instruction
manual for AE-SS/SH and 12. Settings and accuracy in this instruction
manual to understand the characteristics of Electronic trip relay.
10.1 Setting of rated current
(1) Open the front cover of Electronic trip relay.
(2) Connect as described in paragraph 9.
(3) Turn on the power switch on the back panel, and the time counter and other indicator lights at the front.
(4) Set the following with the corresponding switches. The settings are changed in turn by pushing the switches.

When the power is turned on, each item is set to the marked position.
(5) Setting of the rated current
First, set the ratio to CT rating because this tester is designed so that signals are output in percentages (%) of
RATED CURRENT In at Electronic trip relay to RATED CURRENT MAX In max(CT rating).
When the power is turned on, the rated current is set to H1.000 (IN=1.000×INMAX).
① In the case of a C type or S type relay, set the mode to H ○○○○
with the TEST SIGNAL(%) / RATIO
signal level mode switch.
Set to the value of the rated current setting dial of the trip relay with the signal adjusting switches or signal
setting switches.
Example:
In the case where the rated current (IN) is set to 0.8,
set to H0.800 .
② In the case of an M type relay, set as follows:
Example:
In the case where INMAX=1600A and IN=1283A,
1283A÷1600A=0.802, therefore set to H0.802.
③ In the case of measuring the ground fault tripping characteristics, set to H1.000 (even if the rated current is not
set to 1.0).
E-26
10.2 How to operate
Test should be performed only after shutting off the electric power and
verifying that there is no voltage present. Failure to do so may result in an
electrical shock.
DANGER
When current is flowing in the main circuit of breaker, it is combined with the
test signal of Y-2005, consequently does not become correct characteristic.
The operating test should be performed in the state that load current does
not flow in the main circuit.
(1) Set the signal level indicator to ○○○○○.○ by pushing the TEST SIGNAL(%) / RATIO signal level mode switch.
(2) Set the signal level with the signal adjusting switches or signal setting switches in % of IN set in 10.1 (5).

11. Test (for AE-SS/SH)
11.1 LTD Pick-up current test
(1) If the trip relay has the ground fault function (GFR), set the ground fault alarm switch to "ALARM".
(2) Set the signal level to approximately 90% of the pick-up current.
(3) Push the START switch.
(4) Increase the signal with the signal adjusting switch, and measure the pick-up value.
① In the case of a C type or S type relay, the long-time-delay pick-up current is to be taken when the [OVER]
LED of the trip relay lights.
In the case where IU of the S relay is not set to 1.0,
for example, if IU is 0.8 and the [OVER] LED lights are at 94%,
the pick-up value is 94%÷0.8=117.5%.
② In the case of an M type relay, the long-time-delay pick-up current is to be taken when the [100%] LED lights.
(5) Push the STOP switch.
(6) Return the trip relay setting changed in (1) to the initial condition.
11.2 LTD operating time test
(1) Set the signal level to be tested.
① In the case of a C type or S type relay, the operating time is to be taken at 200%, therefore set the signal level
to 00200.0.
In the case where IU of the S relay is not set to "1.0",
for example, if IU is 0.9,
0.9×200%=180%, therefore set the signal level to 00180.0.
② In the case of an M relay,
for example, if the long-time-delay pick-up current (IL) is set to "1.05",
1.05×120%=126%, therefore set the signal level to 00126.0.
(2) Set the short-time-delay pick-up current (IS) setting dial and the instantaneous pick-up current (IＩ) setting dial of the
trip relay to 1.2 times the above-mentioned signal level or more.
If the trip relay has the ground fault function (GFR), set the ground fault alarm switch to "ALARM."
(3) Push the START switch.
(4) After tripping, the operating time is indicated.
(5) Push the RESET switch.
(6) Return the trip relay settings changed in (2) to the initial conditions.
Since Electronic trip relay has a memory effect for overcurrent state, when the operating time test is
interrupted on the way, the operating time at the next test becomes short. This memory effect can be
reset by tripping. Therefore, if operating time test is interrupted on the way, perform the next test
after tripping Electronic trip relay one-time. To trip, perform the trip check in accordance with 11.10.
＜Hint＞
In 11.1 and 11.2, if IU of the S relay is not set to "1.0", the reading of the signal level is regarded as the long-time-delay
pick-up current (%) by setting the value of H○.○○○ to IN×IU.
When measuring the long-time-delay operating time, measurement can be performed with the signal level 00200.0.
When performing the short-time-delay or instantaneous tests, return the setting of H○.○○○ to the initial value.

(4) Read the signal level indicated at the time.
(5) In addition, measure the operating times before and after the short-time-delay pick-up current measured above, and
take the point where the operating time shortens suddenly as the measured value of the short-time-delay pick-up
current (IS).
(6) Return the trip relay settings changed in (1) to the initial conditions.
*
If there is a long delay in increasing the signal, long-time-delay operation may be performed before reaching the
short-time-delay pick-up current. In this case, start again from approximately 95% of the short-time-delay pickup current.
11.4 STD operating time test
(1) Set the instantaneous pick-up current (II) of the trip relay to the maximum. If the trip relay has the ground fault
function (GFR), set the ground fault alarm switch to "ALARM."
(2) Set the signal level to be tested.
For example, if the short-time-delay pick-up current (IS) setting dial is set to 4.5,
450%×1.5=675%, therefore set the signal level to 00675.0.
Here, 1.5 is the value with which the operating time becomes flat.
