Chapter 1 handling precautions

1.1 Outline and characteristic of "UM43FG-E5AK type"

The F-MPC60B is a digital multi-functional digital relay for high-voltage distribution facilities. It is a compact unit produced by combining

the function of protection, measurement, control, kWh pulse output and transmission with a transducer (provided only when the relay

incorporates transducer output).

High reliabilityBy the combination of conventional individual devices, this device realized the following function with difficult realization. The F-

MPC60B improved the function that records the history and fault data.

Improved maintainabilityThe F-MPC60B reduced the time of the relay test by using the trial output for the test. To prevent operation errors such as a mistaken

disconnect of a circuit the F-MPC60B adopted the fail-safe function and the auto monitoring function.

Flexibility

The F-MPC60B is able to change the circuit conditions, such as VT and CT ratio, by changing the setting value.

The F-MPC60B realizes the standardization of wiring in the distribution facilities, reduces the cost of the wiring and the maintenance.

So, the high economic efficiency is demonstrated in the engineering, production and maintenance division by using F-MPC60B.

The features: the F-MPC60B is able to apply to "the 3-pahse 4-wire system for the high or low voltage facilities" and " the 3-pahse 3-wire

system for the high or low voltage facilities ".

Please carefully read this manual before you use the product in order to use it safely and correctly.

1.2 Handling precautions

The F-MPC60B is used in both 100V AC and 100V DC. Provided when the F-MPC60B is used by AC power, use in combinationwith UPS (Power Supply: option) or the F-MPC60 100V AC power supply unit for the F-MPC60B.

The rated CT secondary current is AC 5A. The F-MPC60B detects the current of main circuit: I A, IB, IC and the earth leakage

current: I0. By considering the application circuit and the number of CT, use the F-MPC60B correctly.

(1) Precautions for creating a connection diagram, mounting and wiring Equipment error output is a normally closed contact output (excited in steady state, and if an error occurs, excitation terminates

and contact is closed). Therefore, a lag of around 100ms occurs before the contact opens, since the power was ON (in operation).Consider the use of a timer, if necessary, when creating the external sequence. (See section 2.6.)

If the trip coil open circuit monitor function will not be used set Trip-coil open circuit monitor function at No in the setting.

Refer the code No 63 in the appendix table 3.

The external connector of the product(which incorporates transducer output)consists of a housing(Type:178289-

7,Manufacturer:AMP)and contacts(Type:175218-2,Manufacturer:AMP). Carry out connection treatment using a dedicated manual

tool(Type:919602-1(standard type),914596-3(economy type ))or 90648-1(economy type , Manufacturer: AMP).

Selective input/output (Eight points each) permits selection of function type by setup. See chapter 5 for types of selectable

functions and see chapter 5 for the setup method.Each terminal block is the connector type, and it can be mounted and dismounted by lock screws on both sides of the terminal

block, with wires remaining intact. At the time of mounting/dismounting the terminal block, alternately drive/loosen lock screws

on both sides sequentially. If lock screws on one side only are forcibly tightened (or loosened) the terminal block may be broken.

Certainly tear off the upper and dust-proof seal after the wiring. There is the fear in which that the temperature of the inside rises,

when it is used without tearing off, and that it causes the abnormality and product are shorten.

(2) Precautions of settingThe frequency of this unit is the form of selecting 50Hz or 60Hz.

Set correctly at 50Hz or 60Hz to suit the rated-frequency of application.

In respect to setting items, frequency will not become valid unless the power is ON/OFF after setting. When the frequency

setting is changed, turn ON/OFF the control power once.

As the setting value of the code No 73 and No 74 in the setting table, set the sum of the 100ms and the operating time of external

device. The F-MPC60B spends the time for filtering the input signal, so it is necessary to add the time.

(3) Precautions for shipping the panelFix the front panel door using adhesive tape so that it will not open up due to excessive vibration or the like during loading or

shipping. (It has been assured that the JEC 2500 has been cleared in regard to vibration resistance.)

(4) Precautions for using the external output relayRefer to the Table 3.4 "specification for external input/output". The specification of output current of the relay for ON/OFF/trip

is valid for only the closing current. So, do not use the relay of this devise for tripping the CB current. Use the external relay totrip the CB current.

As the relay except the ON/OFF/trip relay, observe the specification of the section 3.3 (2).

(5) Others Function of OC relay

In case the external CT used as 2CT,use A-phase and C-phase for the CT, and connect the CT secondary synthesized line

(common line) to the B-phase. 2CT provides the overload protect function for the B-phase even against an unbalanced load to the

3-phase circuit as a result. However, it is possible that the B-phase will also operate when single-phase relay testing of A-phase or

C-phase is conducted in a relay test because of this function. (It depends on the positions of test terminal.)

Active electric energy integrated value

The integrated value is also kept when a power failure occurs. If the setting of the VT ratio and CT ratio was changed, however,

the integrated value is reset to the initial value (0).

2. Mounting and wiring2.1 Panel cutting and mountingCut the relay mounting panel as shown in the panel cut drawing in section 3.4 External appearance drawings. Then mount the unit so that

the top face of the unit become level.

Ventilation holes are provided at the top and bottom of the cases main unit. If these holes are plugged, the internal temperature rises and

errors may occur, or it is possible that the products service life will be shortened. When any equipment is mounted above or below the

cases main unit, provide a space of 100 mm or more from the cases main unit.

2.2 WiringWiring to the F-MPC60B is roughly classified as indicated table 2.1. Be careful that these wires do not come in contact with each other.

4.3 Operation when setting

The key switch selects the SET position.

Key switch

Figure 4.2

Step 1 Step 2 Step 4 Step 3

Operation procedure

Step 1

Confirmation of setting value.

The setting value item number and historical value code is updated each time the sheet switch or is pressed, and the

current setting value is indicated by the 7-segment LED.

(Operation for confirmation is step.1 only.)

Step 2

Change to setting value and historical value.

Press sheet switch SET in the state where a setting change item and historical value is selectively indicated in step 1 above. (The

setting value begins to flicker.) to step 3

Step3

The setting value changes each time the sheet switch or is pressed. Select the data to be set.

(The setting value is flickering, and has not yet been finalized.) to step 4

Step 4

When sheet switch ENT is pressed, the setting value is lit continuously; indicating that setting has terminated.

Repeat step 1 to 4 above to continuously change the setting of multiple items. The selecting lock can delete an unnecessary

relay function item. Confirmation of history data and change to the current value can also be performed in the same manner.A list of setting items and history data of the feeder unit, the receiving unit and the bus unit are shown in appendix table 1.

NoteIn the setup for time of monitoring contact open/close jamming, the set time should not be less than external equipment (sequence) motion

(Ans. signal) time plus 100ms. (This is because the F-MPC60B internal measurement time is from CPU output to finalization after the input

filter time.)

(Locking the setting value)

Change to the setting cannot be performed unless the key switch is located in the SET position.

Therefore, mischievous changes to setting cannot be performed by an unspecified person who does not have the key. In addition, a setting

lock function is provided, and a value which was once set cannot be changed even if the key switch is located in the SET position.

(Method for setup of "setting lock".)

Step 1: Setup of setting lock/cancel can be performed only in any of the display statuses indicated below in the normal mode.

Table 4.3 setting lock

Selection of

display item

Operation

IA current display

status Press sheet switches SET and ENT simultaneously. The lock status has been selected if the display is Lon. Or, the

lock has been canceled if the display is LOFF. The Lon/LOFF display is switched each time the sheet switches

indicated above are pressed simultaneously. Terminate the operation, after confirming the Lon is displayed, to the

setting.

Step 2: Assure that the setting value does not flicker even during work step 2 (change to setting value) of the operating procedure indicated

above is performed.


26/68

4.4 Operation in normal stateThe key switch selects NORMAL position.

(Operation of keys is unnecessary during normal running.)As for the display item and display method, see appendix table 2.

Note: " 10" and " 100LED" indicate display magnification in unit indicator LEDs .

when both " 10" " 100" are lit, this indicates that the display magnification is 1,000 times.

Figure 4.3 the operation of normal

Key switch

Normal

The display of measured value can be switched by operating of this switch.

The display of measured value (meter) can be switched during normal running.

The display item is switched sequentially each time the sheet switch or is pressed. Check the display item and unit by reading the

LEDs. The 7-segment LEDs of this unit go out automatically if no switch operation is performed for a continuous 10 minutes, as an

energy conserving measure. However, they light up when any switch operation is performed, any relay is detected or when any equipment

error is detected. (Press one sheet switch to have LEDs to light up again. No change will occur in the running status regardless of whichsheet switch is operated.)

4.5 Rest method of "the measurement hysteresis maximum value", "the measurement hysteresis minimum value" and "theintegrated value".

This appliance has the display function of the hysteresis maximum value, the hysteresis minimum value and integrated value shown at the

bottom table. Please do it by the following in confirmation and the case in which it is reset of period data, etc. And, please similarly reset

field startup test and relay test in the periodic check after the execution on zero-phase current maximum value.

4.6 Operation at testing timeThe key switch selects TEST position. (the function of protection, measurement is all ignored.

The [lamp test (all lamps are lit) status] is produced when the TEST position is selected by the key switch, and switching to [all lamps are

out (code L2 is displayed)] - [input/output testing] - [relay forced motion testing] - [transducer output testing (only with a product with

transducer output)] - [return to lamp test status] each time the sheet switch is pressed thereafter. (Reverse turn occurs when sheet switch

is pressed.)

The contents of input/output testing relay forced motion testing and of transducer output testing are indicated in the Figure 4.5. The test

output is not output even in the test mode, unless the external TEST position input is ON (the CB, etc. have not been pulled out to the TESTpositions). (When the external TEST position is not used, the test output is output in the test mode. Refer to the test position of table 5.2 and

5.5 Description of ON/OFF/trip output motions1) Once the subject input signal is finalized (soft filter about 20ms), the ON/OFF/trip output is continued for one second at minimum even if

the input is gone thereafter. Also CBs trip output permits selection of manual-rest or automatically-reset by setting of the presence or

absence of lockout.

2) When ON/OFF operations are performed simultaneously, the OFF motion takes precedence. Detection of ON signal is made at the

activation (ON) edge. If OFF operation is performed in the state when the ON signal is continuously ON, therefore, OFF output is

made, and the ON output thereafter will not be made until the ON signal is once OFF and is than On again.

3) The ON signal is not accepted during trip output.

4) At setting code No.65, OFF operation of any becomes also effective regardless of the selection of REMOTE-LOCAL of the

operation place, when the OFF precedence was set at with.

(Supplement)

There is the test position input signal as a signal input that is related to the ON/OFF/trip output action.

The test position input signal determines that the CB (switch) is on "the normal operation position or the extraction position.

In the normal operation, the output action is made to be the case in which the external input setting has made to be test position: 21 in

test position input: OFF. And, the output action is done in the test, if it is made to be test position input: ON.

The output action is done with the setting of the key-switch, if the external input is not set at test position: 21.

Chapter 6 Measures to be taken when relay motion or equipment failure occurs, and reading of code display

The code display (7-segment LED of 2 digits) is out during normal running. If it lights up, take the measures indicate below.

6.1 Outline of code displayIf the code display lights up during normal running, it means that a failure occurred in the F-MPC60B main unit or any peripheral

equipment or any relay motion occurred. F represents equipment failure and E represents a relay motion.

6.2 Reading of code display and measures to be taken1) Equipment failure

When an equipment failure is detected, the ALARM LED is lighted, the output of the equipment failure relay is output, and the code is

displayed. If the code display is other than FE, the running is continued and an equipment failure code and normal operation display

(measured data) are displayed as switched about once every second.

F6 is reset automatically when the cause of failure is eliminated. It also goes out when the sheet switch RST is pressed in the state

when the CB is OFF. (If the trip coil open circuit monitor function is not used, set Trip coil open circuit monitoring: None in the

setting.)

F4 and F5 go out when the sheet switch RST is pressed.

Other than the above, execute self-hold when a failure is detected and then goes out when the sheet switch RST is pressed.

Note 1; In the case that the abnormality of the signal is detected in the analogue input circuit, digital input circuit and output relay drive

circuit of this device, the Code display; " F8" is displayed in the 7-segment LED.

There is not abnormality in this device that depends on a temporary factor, in the case that F8 turns off it by pushing the return switch RST.

Therefore, there is not a problem by using this device.

Malfunction has occurred inside this device, in the case that "F8" is displayed even if pushing the switch RST.


34/68

2) Relay motion

When any relay motion occurs, lighting of the relay motion LED and output of an alarm (trip) are performed besides the code display.

Check the cause for relay motion. Description of E codes is printed on the front panel sheet.

When PLURAL FAULTS LEDs are lit, have a code displayed as switched by pressing sheet switch or .

The relay motion display and T-link data are kept after the cause of the failure was eliminated, and they go out when the sheet switch

RST is pressed. If the control power was gone in the state when the sheet switch RST has not been pressed yet, storage is done

automatically, and the status before the power failure occurred is output and displayed when the control power is recovered.

When the E code display is flickering, it means relay detection in motion. (Operates after elapse of timer time.)

Note 1: When the OC relay is actuated, the fault current value (unit A) and the motion time (unit s) are displayed as switched

approximately once every second.

The tripping time display of 51(OC) relay and 51G(OCG) relay is reference value.


35/68

6.3 The method of relay test

Refer to the appendix table 4: "The relay test".

As the relay test is tested at the condition of normal state, the position of the key switch must be the normal.

(When the position of the key switch is the test, the protection function of F-MPC60B does not act at all.)

The note at the test

(1) The Table 6.3 shows the allowable continuous current at input circuit of the phase current. Refer to the Table 6.3 when the operation

time is tested.

Table 6.3 the allowable continuous current (for the F-MPC60B that the secondary rating current is 5A.)

The input current The time of the allowable continuous

current

The input current The time of the allowable continuous

current

15-20A 100 s 80-100A 4.0 s

20-40A 25 s --- ---

The overload capacity of the current input circuit is 200A, 1s and 2 times: 60 s as an interval. Refer to Figure 6.1 when the operation time is

tested.

Figure 6.1 the overload capacity of the current input circuit

(2) The F-MPC60B has the band-pass-filter to prevent the wrong action by the harmonic current, and changes the circuit constant of the

band-pass-filter using the setting value of the frequency: 50Hz or 60Hz. So, at the relay test, set up the setting value, and input the signal that

has the same frequency with the setting value.If the generator is used at the test, keep the accuracy oh frequency: 2.5% or more less.

Note 1: the alarm output, the communication and the display on the panel of F-MPC60B output the errors detected by self-diagnosis.

Note 2: the controller is able to check the setting value by using the communication.

The main purpose of the daily check is the check such as the appearance and structure of a relay and also switchboard. As for the dailycheck, carry out several months to the rough standard. Also, carry out the inspection promptly, in the case that it corresponds to the next

item.

(1) It is in the case that abnormality admitted the fear that occurs with the daily check and the periodic check.

(2) It is in the case that the abnormality occurred with automatic monitoring (continuous monitoring /automatic inspection) the function.

(3) In the case that the setting value and the sequence circuit of the relay are changed.

As for the periodic check, carry out 1 time to the rough standard in 4 years from 2.

As for the method of the relay test, refer to Section 6.3 ant appendix 4: "The relay test".

7.2 Design lifeThe exchange part in a periodic check does not exist. The design life value type of F-MPC60B is 15 years at ambient temperature 40 per

a year. If temperature goes up 10 life becomes to about half. The vent (the slit) is opening to the upper part and lower part of the case

main body. There is the fear that the product life becomes short, because the inside temperature goes up when the vent of this device is

closed. Therefore, avoid it to close the vent.

Please understand, because also, the design life is not the guarantee-life. Exchange this device when this device reached life.

The relay test is a test in relay operation value and operation time in the normal operation condition. Therefore, key SW

is an operating state of "NORMAL" position and the relay test is done.

(In "TEST" position, the protective function does not work in key SW.)

The attention of the test

This appliance contains the band-pass filter in order to prevent the unnecessary operation according to the harmonic.

And, the circuit constant of the band-pass filter is being switched by the 50/60Hz selection setting in the main body

inside.Still, please make the output frequency of the generator to be within 2.5% of set rated frequency in the case

of the relay test by the generator.

The method of the test

In proportion to the unit type, characteristic test content and decision value refer to the after next page.

The following are shown in the following: Identification method of the operation value and identification method in

operation time.

Test item The method of test

Operation

value

(note)

The signal is applied to the input terminal, and it gradually changes, and the value in which 7segLED

started the "E" flashing display is the operation value.

However, operation value in case of the short time operation type is any of value that "E"

continued and that it lit, and that it displayed it or the value which output the trip ( alarm ).

Operation

time

The adjustment-finished signal is applied to the input terminal, and the time until a trip (alarm) output

operates is measured.

Note:

The signal value in the pickup relay output action becomes the operation value in trouble pickup output setting (code

of 81) in any of the selective output 1-8.
