[Other precautions]

(1) Common precautions

Do not slant the connector when attaching or removing the test connector to/from a breaker. (Fig. 3)

Doing so may break the test connector. Do not hold the cable but the tip of the test connector when attaching or removing the test connector.

Do not use a test connector which has been attached and removed 1,000 times or more or a broken test connector for testing

Testing may not be able to be performed correctly.

Remove the test cable from Y-360 and replace it with a new one. (Refer to Section 4.2)

Do not subject the Y-360 to impacts during testing. Doing so may abort the test and reset the display screen.

On the test screen, the batteries will be exhausted. If LOW BAT is displayed, replace batteries with new ones.

When you turn on the POWER switch, do not touch other switches (START/STOP switches, operation switches).

When the POWER switch is instantaneously turned on and off, the stored screen may be LOW BAT.

When the test connector is disconnected after testing, close the test cover or transparent cover of the circuit breaker to return it to its original state.

(2) Precautions for using an MDU breaker

If the Y-360 is connected while the control power is applied to the MDU unit, the power amount and the reactive power amount may decrease

(or return to the values of 30 minutes ago at the maximum).

Before connecting the Y-360, turn off the control power of the MDU unit or set them by the power amount setting.

The power amount when the control power supply is turned off is stored when the control power supply of the MDU unit is turned off.

Follow the Instruction Manual for the MDU breaker for the power amount setting.

(3) Precautions for using a WS-V series circuit breaker

When conducting a trip test on a circuit breaker with a pre-alarm module (PAL), remove the connection cable between the circuit breaker and the pre-alarm

module in advance. The connection cable can be connected/disconnected via the lock connector on the pre-alarm module side. (Fig. 5) (Note 1)

WS-V series circuit breakers with DP (current display) come with a pre-alarm module as standard.

Before conducting a trip test, be sure to remove the connection cable. (Fig. 5) (Note 1)

When a trip test is conducted with the connection cable of the pre-alarm module disconnected, the display of the breaker lights up when power is supplied from the

Y-360.

After the test is completed, the display goes off to prevent battery drain. This has no influence on the breaker operation.

After conducting the trip test, connect the cable between the circuit breaker and the pre-alarm module. (Note 2)

Note 1: Operation may not be performed unless the connection cable has been removed.

Note 2: Connect the pre-alarm module when conducting tests other than a trip test

(pre-alarm operating current test, pre-alarm operating time test, contact output test, model information).

(4) Precautions for using "NF250-SEV/HEV with MDU" and "electronic circuit breakers (with display)"

If the Y-360 is connected while the control power is applied to the MDU and a pre-alarm module, "Now Testing ..." is displayed on the display.

Note that the functions of the MDU and current display cannot be used.

(5) Precautions when setting the operating characteristics

When setting the operating characteristics, make sure of the following. Refer to the instruction manual for the circuit breaker for details on the settings.

Precautions for setting the STD pickup current (Is) and the INST pickup current (Ii)

* When the STD pickup current (Is) is set to be equal to or larger than the INST pickup current (Ii), the STD operation does not occur.

The Y-360 can only set the operating characteristics for WS-V series. Set the overcurrent trip operating characteristics of W&WS series using the dial on the front of the circuit breaker.

Refer to the instruction manual for the circuit breaker for details. Note that the LTD I6t characteristics and STD I2t characteristics (lamp characteristics) are always ON.

The overcurrent trip operating characteristics of MDU breakers can be checked on the MDU. Refer to the instruction manual of the MDU breaker for details.

the overcurrent trip operating characteristics of WS-V MDU breakers can also be set on the MDU.

When performing the LTD trip operating time test (5.3.2.2) or pre-alarm operating time test (5.3.5.2), if performing the test with a current signal level other than 200%,

set the STD tripping current (Is) and INST tripping current (Ii) to one of the following.

[1] Set the current signal value to 90% or less of the Is or Ii setting value of the circuit breaker.

[2] Set the Is or Ii of the circuit breakers to the maximum value.

(1) When the STD pickup current (Is) exceeds the INST pickup current (Ii) Example: NF250-SEV when Ir is 250 A

When "Is is 3 x Ir" and "Ii is 2 x rated current," Is becomes 750 A and Ii

becomes 500 A, and the INST trip operation occurs in priority to the STD trip

operation.

The operating characteristic curves are as shown in the following figure.

(2) When the STD pickup current (Is) is equal to the INST pickup current (Ii) Example: NF250-SEV when Ir is 250 A

When "Is is 3 x Ir" and "Ii is 3 x rated current," Is becomes 750 A and Ii

becomes 750 A, and the INST trip operation occurs in priority to the STD trip

operation.

The operating characteristic curves are as shown in the following figure.

5. 3 Test method 5. 3. 1 Test selection method

Select ETR TEST from the Main Menu screen and press the ENTER switch. Then the Select Test (ETR TEST) screen appears.

Select a test item by pressing the UP or DOWN switch. You can go to the selected test screen by pressing the ENTER switch.

Do not trip test the main circuit of a circuit breaker with voltage applied. This leads to the dangerous state where the circuit breaker trips or an arc is generated. When conducting a trip test on a WS-V series with the pre-alarm module (PAL), remove the connection cable between the circuit breaker and the pre-alarm module in advance. (Refer to Fig. 5 in "5.1 Procedure and precautions for use" for details.) Before conducting a test other than a trip test, be sure to connect the connection cable between the circuit breaker and the pre-alarm module.

When an LTD trip test (pickup current test) is interrupted and a pre-alarm operation test is performed, the operating time may be shorter when continuing testing as the breaker stores the current. If you did, trip the breaker once during a test such as an INST trip test and then conduct the test.

When conducting an operation test on the pre-alarm module (PAL) or TI module (alarm contact output) of a WS-V series or W&WS MDU breaker, perform the procedure in "5.6 Contact Output Test". Alarm contact output cannot be reset while the Y-360 is connected.

5. 3. 2 LTD trip test

5. 3. 2. 1 LTD trip operating current (pickup current) test (1) Select LTD PU/TIME on the Select Test (ETR TEST) screen and press the ENTER switch to go to the LTD Trip Test (LTD PU/TIME) screen.

(2) Set the current signal level by pressing the UP or DOWN switch. (Screen 1)

Note that if the current signal level you set is too high, the breaker will trip in a short time.

(Example: For NF250-SEV, if the current signal level is set to 600% when TL is 100 s, the breaker will trip in about 10 s.)

(3) When you press the START switch, the time counter starts counting up to indicate that the current signal is being output. (Screen 2)

(4) Adjust the current signal level by pressing the UP or DOWN switch and check the current signal level at the time when the OVER indicator on the Y-360 test screen

turns on. (Fig. 1 and 2)

For a WS-V series or W&WS MDU breaker, the current signal level can also be checked when the OVER indicator Turns ON on the Y-360 test screen. (Screen 3)

(5) The result is good if the signal level is within the reference range in the test reference chart (refer to Table 1-1, and Table 2 on p. 18 and p. 19). (Screen 3)

For a WS-V series or W&WS MDU breaker, it should be between 105% and 125%. (It does not depend on the current setting.)

For a W&WS series circuit breaker, refer to Table 2 for the signal level considered good, because the signal level where the OVER LED lights up depends on the

current setting.

(Example: For NF400-SEW, when the current setting is 200A, it should be between 53% and 62%.)

(6) When you hold down the UP/DOWN switch, the current signal level changes by 1% at first. When you keep holding it further, it changes by 10%.

(7) Press the STOP switch to stop output of the current signal.

5. 3. 2. 2 LTD trip operating time test If a test such as the operation current test of an LTD trip test is performed immediately before this test, trip the breaker once during a test such as an INST trip test

and then conduct this test again. The correct operating time may not be displayed.

(1) Select LTD PU/TIME on the Select Test (ETR TEST) screen and press the ENTER switch to go to the LTD Trip Test (LTD PU/TIME) screen.

(2) Set the current signal level by pressing the UP or DOWN switch. (Screen 1)

For a WS-V series or MDU breaker, set it to 200%.

For a W&WS series circuit breaker, align with the 200% signal level (%IT) on Table 2 of p. 19.

(Example: For the NF400-SEW 300A, set the current signal level to 150%.)

(3) When you press the START switch, the current signal is output and time counter starts counting up.

In this case, the 70%, PAL, and OVER LED light up for W&WS series and the OVER LED lights up for a WS-V series. (Fig. 1 and 2)

For a WS-V series or W&WS MDU breaker, the OVER indicator of the Y-360 test screen turns on. (Screen 2)

(4) The circuit breaker trips predetermined time has passed and the time counter stops.

At this time, TRIP indicator on the T-360 test screen turns on. (Screen 3)

(5) The result is good if the time counter value is within the reference range in the test reference chart (refer to Table 1-1, and Table 2 on p. 18 and p. 19).

(Example: When TL is 100 s, it should be between 80 and 120 s.)

(6) When you reset and turn on the breaker and then press the START switch, you can conduct an operating time test again.

(7) Press the STOP switch to cancel the test. To continue performing an operating time test, trip the breaker once during a test such as an INST trip test first.

* Testing is possible with the current signal at a value other than above. Refer to "(5) Precautions when setting the operating characteristics" on p. 10 for the setting

details.

5. 3. 3 STD trip test (operating time test)

Check the setting value of the INST pickup current Ii before conducting this test.

When the setting value is equal to or lower than "current signal level for STD trip test," an INST trip operation may occur, thus the STD operating time may not be

displayed.

(Example: For NF250-SEV, when Ir is 250 A, Is is 4 x Ir, and Ii is 5 x rated current, Is is 1000 A and Ii is 1250 A. 0.01 s is displayed as the operating time because the

current signal level is Is x 1.5 = 1500 A, and this exceeds the INST tripping current.)

(1) Select STD TIME on the Select Test (ETR TEST) screen and press the ENTER switch to go to the STD Trip Test (STD TIME) screen.

You cannot change the current signal level in this mode. (Screen 1)

(2) When you press the START switch, the current signal is output and the breaker trips.

At this time, TRIP indicator on the Y-360 test screen turns on. (Screen 2)

(3) The result is good if the time counter value is within the reference range in the test reference chart (refer to Table 1-1, and Table 2 on p. 18 and p. 19).

(Example: When Ts is 0.3 s, it should be between 0.22 and 0.34 s.)

(4) When you reset and turn on the breaker and then press the START switch, you can conduct a STD trip test again.

(5) Press the STOP switch to cancel the test. To continue performing an STD trip test, trip the breaker once during a test such as an INST trip test first.

5. 3. 5 Pre-alarm operation test

5. 3. 5. 1 Pre-alarm operating current (pickup current) test Can be performed for a WS-V series when a pre-alarm module (PAL) is included.

Confirm that the pre-alarm module is connected.

For a W&WS series circuit breaker with a PAL contact, connect this contact to an insulating relay. (Refer to (3) in Section 5.1.)

(1) Select PAL PU/TIME on the Select Test (ETR TEST) screen and press the ENTER switch to go to the Pre-alarm Test (PAL PU/TIME) screen.

(2) Set the current signal level by pressing the UP or DOWN switch. (Screen 1)

(3) When you press the START switch, the time counter starts counting up to indicate that the current signal is being output. (Screen 2)

(4) Adjust the current signal level by pressing the UP or DOWN switch and check the current signal level at the time when the PAL LED of the circuit breaker flashes (for

a W&WS series). (Fig. 1 and 2)

For a WS-V series or W&WS MDU breaker, the current signal level can also be checked when the PALPU indicator on the Y-360 test screen turns on.

(5) The result is good if the current signal level is within the reference range in the test reference chart (refer to Table 1-2, and Table 2 on p. 18 and p. 19). (Screen 3)

When the pre-alarm current Ip = Ir x 0.7 for a WS-V series or W&WS MDU breaker, it should be between 60% and 80%. (It does not depend on the current

setting.)

For a W&WS series circuit breaker, refer to Table 2 for the signal level considered good, because the signal level where the PAL LED starts flashing depends on

the current setting.

(Example: When the pre-alarm current Ip = In x 0.7 for NF400-SEW, with the current set to 200 A, it should be between 30% and 40%.)

(6) When you hold down the UP/DOWN switch, the current signal level changes by 1% at first. When you keep holding it further, it changes by 10%.

(7) Press the STOP switch to stop the output of the current signal.

5. 3. 5. 2 Pre-alarm operating time test Can be performed for a WS-V series when a pre-alarm module (PAL) is included.

Confirm that the pre-alarm module is connected.

For a W&WS series circuit breaker with a PAL contact, connect this contact to an insulating relay. (Refer to (3) in Section 5.1.)

If a test such as the operation current test of an LTD trip test is performed immediately before this test, trip the breaker once during a test such as an INST trip test and

then conduct this test again.

(1) Select PAL PU/TIME on the Select Test (ETR TEST) screen and press the ENTER switch to go to the Pre-alarm Test (PAL PU/TIME) screen.

(2) Set the current signal level by pressing the UP or DOWN switch. (Screen 1)

For a WS-V series or W&WS MDU circuit breaker, set it to 200%.

For a W&WS series circuit breaker, align with the 200% signal level (%IT) on Table 2 of p. 19.

(Example: For the NF400-SEW 300A, set the current signal level to 150%.)

(3) When you press the START switch, the current signal is output and time counter starts counting up.

For a WS-V series or W&WS MDU breaker

In this case, for a W&WS MDU breaker, the 70% and OVER LED light up and the PAL LED flashes. (Fig. 1)

For a WS-V series, the OVER LED lights up. (Fig. 2)

The PALPU indicator on the Y-360 test screen turns on. (Screen 2)

For a W&WS series circuit breaker

In this case, the 70% and OVER LED of the breaker light up and the PAL LED flashes. Nothing is displayed on the Y-360 test screen.

(4) The time counter stops. (Manually stop when nothing is connected to the PAL terminal of a W&WS series cercuit breaker.)

For a WS-V series or W&WS MDU breaker

The time counter automatically stops when the predetermined time has passed, and the PALOUT indicator on the Y-360 test screen turns on. (Screen 3)

For a W&WS series circuit breaker

[1] When the PAL terminal is connected, the time counter automatically stops when the specified time elapses, and the PALOUT indicator on the test screen

lights up. (Screen 3)

[2] When nothing is connected to the PAL terminal, press the STOP switch of the Y-360 at the same time that the PAL LED of the circuit breaker switches from

flashing to being lit up to stop the time counter. (The time counter does not stop automatically.)

(5) The result is good if the time counter value is within the reference range in the test reference chart (refer to Table 1-2, and Table 2 on p. 18 and p. 19).

(Example: When the pre-alarm current Ip = Ir x 0.7 and TL is 100 s, it should be between 40 and 60 s.)

(6) Press the STOP switch to cancel the test.

When you conduct another operation test immediately after this test, trip the breaker once in a test such as an INST trip test in advance.

* Testing is possible with the current signal at a value other than above. Refer to "(5) Precautions when setting the operating characteristics" on p. 10 for the setting

details.

* Perform testing with a current signal where the operating time will be 3 s or longer for WS-V series or W&WS MDU breakers. (The detection time may be delayed if the

operating time is less than 3 s.)

* When stopping self-holding type PAL alarm output, press the pre-alarm reset switch or use the RETURN switch to display the test selection screen. The automatic

reset type PAL alarm output automatically stops after testing is complete for WS-V series or W&WS MDU breaker.

(Refer to the manual of the pre-alarm module or manual of the circuit breaker for information on the self-holding and automatic reset type alarm output.)

5. 4 Setting the operating characteristics

For WS-V series only, the operating characteristics can be set by editing them with the Y-360 and sending them to the circuit breaker.

Set the operating characteristics of W&WS series using the dials on the front of the circuit breaker.

Perform the setting procedure with the circuit breaker off or in the tripped state.

Refer to the instruction manual for the circuit breaker for other details.

5. 4. 1 Configurable operating characteristics (only the WS-V series can be set)

The configureable operating characteristics are indicated below.

[1] LTD operating time TL (Selectable from 12, 60, 80 and 100 s)

[2] Ramp characteristics of LTD (I6t ON/OFF selection)

[3] STD pickup current Is (Selectable from 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 10 x Ir)

[4] STD operating time (Ts) (Selectable from 0.1, 0.2 and 0.3 s)

[5] Ramp characteristics of STD (I2t ON/OFF selection)

[6] Neutral pole protection ON/OFF selection (selectable only for LTD characteristic setting of 4-pole breakers.)

The items available with the Y-360 are indicated above the operating characteristic curves of the circuit breaker in the figure below.

The rated current Ir and the INST pickup current Ii can be set with the setting switch on the breaker, while the pre-alarm pickup current Ip can be set with the setting

switch on the pre-alarm module.

5. 4. 2 Selecting the characteristic setting method (only the WS-V series can be set)

The following two methods are provided for setting the operating characteristics.

[1] Method for reading the setting information from the connected breaker to change the settings

Enables the settings to be configured while checking the current settings of the circuit breaker. Used when setting different characteristics for each device.

[2] Method for configuring settings by sending the preset values stored in Y-360 to the breaker

The procedure for changing the setting values can be skipped when setting the same values for multiple devices. Up to four patterns of settings information can be

stored.

The setting procedure is indicated below.

Select PROTECT SET from the Main Menu screen and press the ENTER switch to display the file selection screen.

Pressing the UP or DOWN switch changes the menu items as follows: ETR File 1 File 2 File 3 File 4 ETR

[1] To read the setting information from the connected breaker to change the settings, select ETR.

[2] To configure settings by sending the preset values stored in Y-360 to the breaker, select File 1, File 2, File 3, or File 4.

By pressing the ENTER switch on the Select File (PROTET SET) screen, you can go to the Set Characteristics (PROTECT) screen of ETR or the file you selected.

By selecting ETR on the Select File (PROTECT SET) screen and pressing the ENTER switch, you can load the characteristic setting values of the currently

connected breaker.

(For the procedute, refer to the next page.)

5. 4. 4 Sending the setting values (only the WS-V series can be set) You have not completed changing the characteristic setting values of the breaker yet when you changed only the characteristic setting values in Section 5.4.3. (Only

the setting values of the Y-360 have been changed.)

* By sending the setting values to the breaker, you can actually change the setting values of the breaker.

After changing the characteristic setting values in Section 5.4.3, send them to the breaker.

(1) Select TRANSMIT on the Set Characteristics (PROTECT) screen using the SELECT switch and press the ENTER switch. (Screen 1)

(2) When the Permit Sending (TRANSMIT) screen is displayed, select YES by pressing the UP or DOWN switch and then press the ENTER switch. (Screen 2)

Screen 3 Screen 4

5. 4. 5 Setting the same characteristics to multiple breakers repeatedly (only the WS-V series can be set)

(1) Storing the setting values

Store the setting values in the Y-360 in advance. For storage, select File 1, File 2, File 3, or File 4 on the Select File (PROTECT SET) screen as described in Section

5.4.2.

After that, the setting values changed in Section 5.4.3 are stored in the Y-360. You can perform this process without connecting the Y-360 to the breaker.

(2) Sending the setting values to the breaker

Connect the Y-360 that stores the setting values to the desired breaker.

Select a file (any of File 1, File 2, File 3, and File 4) that holds the setting values on the Select File (PROTECT SET) screen as described in Section 5.4.2.

After that, perform Section 5.4.4 (1) (2) operation and send the set value.

(3) Set the same characteristics to other breakers repeatedly.

When Step (2) above is completed, the Y-360 is still displaying the Set Characteristics (PROTECT) screen of the file you selected. Therefore, disconnect the breaker

whose setting has been completed from the Y-360 and then connect the Y-360 to a breaker to be set next. (The power of the Y-360 must be kept on.)

After connecting Y-360 to another breaker, take Steps (1) and (2) of Section 5.4.4. This is the end of the setting of this breaker.

By repeating this procedure, you can set the same characteristics to multiple breakers.

(4) After all settings are completed, check the setting values collectively.

You cannot check if the setting values have been properly changed only by taking the procedure above. Therefore, be sure to check them after completing the

setting.

You can also check the settings repeatedly. According to the procedure described in Section 5.5, check the model information of the first breaker.

After completing checking, disconnect the Y-360 from the breaker that has already been checked with the Model Information (ETR INFO.) screen displayed. Then,

connect Y-360 to a breaker whose settings are checked next. (The power of the Y-360 must be kept on.)

After connecting the Y-360 to another breaker, press the START or STOP switch. Then, the setting values are read from the breaker and you can check them on

the Model Information (ETR INFO.) screen.

By repeating this procedure, you can check the setting values of multiple breakers.

6. Troubleshooting 6. 1 When you think the Y-360 may have failed

Symptom Cause and solution Reference

Nothing is displayed on the screen when the

POWER switch is turned on.

The batteries may have been inserted with the incorrect terminal orientation (+/-). Check

the orientation of the batteries. P7

When the Y-360 test connector is connected to a

breaker, the display of the MDU unit lights up red.

You may have inserted or removed the test connector with the POWER switch of the Y-

360 set to ON and during the test.

If so, turn off the POWER switch of the Y-360 and remove the test cable.

This has no influence on the breaker operation.

P7 to P10

In an operating time test, the breaker does not trip

even when the predetermined time has passed.

(For a breaker with a pre-alarm module (PAL))

With a WS-V series, remove the connection cable of the pre-alarm module before

conducting a test.

P8 to P10,

P12 to P15

After an operation test is completed, the display of

the breaker turns on and off repeatedly.

(For a breaker with display)

To prevent battery drain, the display of the breaker goes out after an operation test is

completed for WS-V series.

This is not a breaker failure and has no influence on the breaker operation.

P10

Though the setting switches of the breaker and pre-

alarm module have been changed, their settings are

not applied to the Model Information (ETR INFO.)

screen.

Press the START or STOP switch to update the display. P27

In a pre-alarm operating time test, PALOUT lights up

earlier than the predetermined time.

Check the following.

Did you conduct a pickup current test before conducting this test?

If you did, trip the breaker once during a test such as an INST trip test and then conduct

this test again.

Check the STD pickup current Is and the INST pickup current Ii.

If Is is equal to or larger than Ii, the STD operation does not occur.

Confirm that there are no sources of strong electromagnetic fields or noise nearby, such

as lines passing a high current.

If there is, remove the Y-360 and test cable away from the source and perform the test

again.

Check if the test cable is connected properly because it may not be connected properly.

The test cable may be deteriorated or broken.

Replace the test cable with a new one when the test cable has been inserted and

removed 1,000 times (as a guide).

P7,

P8 to P10,

P12 to P15,

P17 In an LTD/STD trip operating time test, the breaker

trips earlier than the predetermined time.

The screen indicates that the W&WS series circuit

breaker is connected despite the WS-V series being

connected.

Check the following.

Check if the test cable is connected properly because it may not be connected properly.

The test cable may be deteriorated or broken.

Replace the test cable with a new one when the test cable has been inserted and

removed 1,000 times (as a guide).

P7,

P12 to P17

If not, the circuit breaker may have failed. Please contact a dealer or the Mitsubishi Electric System & Service Co., Ltd. or Mitsubishi Electric branch office indicated on

the back cover of this manual.

If abnormal noise, smell, smoke, or heat is emitted from the Y-360, turn OFF the power of the Y-360 immediately, remove the batteries, and stop use.
