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.

1Set the Signal level indicator to . by pushing the Signal level mode switch TEST SIGNAL(%) / RATIO .

2Set a signal level in % of Ir by using the Signal adjusting switches or Signal setting keypad.

When using the Signal adjusting switches:

When using the Signal setting keypad:

Push a clear key C .

Since figures are shifted to left every time you

push numerical keys, enter the desired values.

Push a set key SET .

3Push START switch, and the test signal is output. Then the time counter starts from 000.000 , and also the TESTING

mode indicating LED lights.

4Push STOP switch, and the test signal is stopped. Then the time counter stops, and the TESTING mode indicating LED

goes off.

In case of tripping, the TRIP indicating LED lights and the time counter stops automatically.

5Push RESET switch to reset the TRIP indicating LED and the time counter. This switch is used for retesting.

Continuing to push the switches increases or decreases the signal level continuously.

To set to 200%Ir, push C 2 0 0 0 SET ,

and 00200.0 is set.

E-8

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

1Set the signal level to approximately 90% of LTD pick-up current.

2Push START switch.

3Increase the signal level with Signal adjusting switch, and take a reading of pick-up value.

iIn 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%.

iiIn case of WM type relay

The LTD pick-up level can be taken at a point where ETR turns a [100%] LED on.

4Push STOP switch.

5Push RESET switch and start at (1), if testing again.

5.2 LTD operating time test

1Set a desired signal level.

iIn 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 0.9200%=180%, set the signal level to 00180.0 .

iiIn case of WM type relay

The operating time is to be taken at 120%IL, therefore, if IL is set to 1.05, since 1.05120%=126%,

set the signal level to 00126.0 .

2The 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.

3Push START switch.

4After tripping, the operating time is indicated.

5Push 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 IrIu. 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.

5. Test (for AE-SW)

5.3 STD Pick-up current test

1Set 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).

2Set the signal level to approximately 80% of Isd.

3Push 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.

4Read the signal level indicated at the time.

5Furthermore, 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.

6Push RESET switch and start at (2), if testing again.

5.4 STD operating time test

1Set Ii setting dial of ETR to the maximum.

2Set a desired signal level.

For example, if Isd setting dial is set to 4, since 400%1.5=600%, set the signal level to 00600.0 .

*Where, 1.5 is a value that the operating time becomes flat.

3Push START switch.

4After tripping, the operating time is indicated.

When the stop signal is made by the main contact, auxiliary switch (AX) or OCR alarm switch (AL).

Take the reading of the counter as it is.

When the stop signal is made through the test connector of ETR or alarm contacts of Power supply module (type: P3, P4 or P5).

Add 20ms (mechanical operating time) to the reading of the counter.

5Push RESET switch and start at (3), if testing again.

If ETR operates as LTD or INST in checking STD pick-up current, change the set value of INST/LTD,

or change the test current. Moreover, ETR may operate as INST when checking STD operating time at

Isd=10. In this case, lower the test current to near 140%Isd, or lower the test current after setting Tsd

to I2t OFF temporarily.

operating time with accuracy, push the Test power manual connecting switch VT , and push

START switch after the Test power indicating LED lighting. If do not pushing the Test power

manual connecting switch VT , exact measurement cannot be performed.

5.7 MCR function check (*Only when MCR switch is equipped)

1Set Ii setting dial of ETR to "MCR" side.

2When the state of circuit breaker is off, ETR operates as INST.

Check the INST operation in accordance with section 5.5 and 5.6.

* This test is checking that instantaneous characteristics is effective

during breaker closing operation ( from open to close ) .

3Confirms that the breaker does not operate as INST even when the same test as section 5.5 and 5.6 is carried out. In this case,

it operates as STD in case of WS or WM type relay. In case of WB type relay, it does not trip.

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.

(The function of each setting, see paragraph 8).

Output frequency 50Hz , 60Hz

Stop signal a , b, ETR

Output pin S1 , S2, S3

Test mode usual test , TRIP CHECK

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=1.000INMAX).

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 .

In the case of an M type relay, set as follows:

Example: In the case where INMAX=1600A and IN=1283A,

1283A1600A=0.802, therefore set to H0.802.

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).

10.2 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 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).

When using the signal adjusting switches

When using the signal setting switches

Push the C (clear) key.

Since figures are shifted to the left every

time you push the numeral keys, indicate

the desired value.

Push the SET key.

(3) START Push the [START] switch, and the test signal is output, the time counter starts from 000.000, and also

the [TESTING] mode indicating LED lights.

(4) STOP To stop testing, push the [STOP] switch, and the test signal is stopped, the time counter stops, and

also the [TESTING] mode indicating LED goes out.

(5) With tripping, the TRIP indicating LED lights, and the time counter stops. Read the operating time at the time counter.

(6) RESET Push the [RESET] switch to reset the TRIP indicating LED and the time counter, so that testing can

be restarted.

To set 200%, push C 2 0 0 0 SET, and

0200.0 is set.

Continuing to push the switches

increases or decreases the signal

level continuously.

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.

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%.

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.

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,

0.9200%=180%, therefore set the signal level to 00180.0.

In the case of an M relay,

for example, if the long-time-delay pick-up current (IL) is set to "1.05",

1.05120%=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 (I) 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 INIU.

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.

11. Test (for AE-SS/SH)

E-29

11.3 STD Pick-up current test

(1) Set the instantaneous pick-up current (II) setting dial of the trip relay to the maximum.

Set the short-time-delay operating time (TS) to 0s. (minimum).

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 80% of the short-time-delay pick-up current.

(3) Push the START switch, immediately increase the signal with the

signal adjusting switch until Electronic trip relay trips and Time counter

LED stops.

(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 pick-

up 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.

(3) Push the START switch.

(4) After tripping, the operating time is indicated.

When the stop signal is made by the main

contact or auxiliary switch (AX) Take the reading of the counter as it is.

When the stop signal is made through the test

connector of Electronic trip relay

Add 20ms. (mechanical operating time) to the

reading of the counter.

(5) Push the RESET switch.

(6) Return the trip relay settings changed in (1) to the initial conditions.

(7) Be aware that instantaneous operation may be performed near the instantaneous pick-up current (II) due to the

influence of the signal making phase.

* If the MCR/INST switch of the trip relay is set to MCR when the circuit breaker is on, instantaneous operation

is not performed but short-time-delay or long-time-delay operation is performed.

11.6 INST operating time test

(1) Set the signal level to be tested.

For example, if the instantaneous pick-up current (I)

setting dial is set to "10",

1000%1.5=1500%, therefore set the signal level to

01500.0.

* Here, 1.5 is the value with which the operating

time becomes flat.

(2) Push the START switch with the [STD LOCK] switch of the trip relay pushed.

(3) After tripping, the operating time is indicated.

When the stop signal is made by the main

contact or auxiliary switch (AX) Take the reading of the counter as it is.

When the stop signal is made through the test

connector of Electronic trip relay

Add 20ms. (mechanical operating time) to the

reading of the counter.

(4) Push the [RESET] switch.

When checking the short time operation such as INST operating time test, in order to measure the

operating time with accuracy, push the Test power manual connecting switch VT , and push

START switch after the Test power indicating LED lighting. If do not pushing the Test power

manual connecting switch VT , exact measurement cannot be performed.

11.7 MCR function check

(1) Set the INST/MCR switch of the trip relay to MCR.

Set the stop signal of Y-2005 to ETR.

(2) Instantaneous operation is performed with the circuit breaker off.

Check the instantaneous operation in accordance with 11.5 and 11.6.

* This test is checking that instantaneous characteristics is effective during breaker closing operation (from open to close).

(3) Instantaneous tripping characteristics disappear with the circuit breaker on.

Set the signal level exceeding the instantaneous pick-up current (I), and check that instantaneous operation is not performed.

For example, if the ground fault pick-up current (IG) is set to "0.3",

30%1.5=45%, therefore set the signal level to 00045.0.

* Here, 1.5 is the value with which the operating time becomes flat.

(4) Push the START switch.

(5) After tripping, the operating time is indicated.

When the stop signal is made by the main
