Integrated Digital Motor Protection Relay based on MCU(Microprocessor Control Unit)

Real Time Processing and High Precision are implemented.

Applicable to invertor circuits

It may be applied to the secondary inverter control circuit with its outstanding resistance to harmonic noise.

Permissible frequency range is 10~200Hz. When the percentage of harmonic is more than 30%, a harmonic filter is installed. (However, the ground fault protection function should be switched off.)

Function to store the cause(s) of failure / Fault

Up to 5 motor failure events may be saved in the system, so that the failure history can be easily identified.


The display part is separated and attached to the front panel, so that information on current/operating time and setup can be viewed without taking out the unit. With the separated display, motor protection can be performed.


~100A

~100A network configurations. Models with analog current signal (4~20mA DC) output are compatible with systems that uses the existing TD (Transducer).

A wide range of reset functions

Manual/Automatic/Electrical reset functions are provided for user convenience.

Date information display

When a failure occurs, the date and time of failure occurrence are saved in the system to accurately identify the date of motor failure.

Password setting

When changing the set values, a password must be inserted.

Thermal Inverse Time, Inverse Time and Definite Time Modes

According to user’s needs, the motor can be protected in the inverse time mode or definite time mode.

~100A

Three-phase digital ampere-meter

Three-phase current is displayed in cycle at intervals of 2 seconds for operators to check the motor state.

Various protection elements and additional functions

Single/3-phase is optional, and output contact as well as the operating time can be set.

Free Voltage power connection (AC/D85~260V) is possible with ZCT built-in option.

High Reliability

The current relay error is reduced from 5% to 3% and the minimum sensible current is lowered from 70% to 30% of the minimum rating. Phase fail/phase unbalance protection relay correction and delay time can be set.

Inverse time characteristic good for motor protection

Thanks to the inverse time characteristic in which a running time is determined by a size of overcurrent, the equipment is excellent at motor protection.

Product characteristics

Protection functions

Over current. Overload

Considering the start-up time of a motor and based on 600% of the rated current, operating time is set by 1sec unit ranging from 1 to 60 seconds to establish an overload characteristic curve (Class 1~60). When a definite time characteristic is chosen, overcurrent is detected from the set operating delay time (D-Time) regardless of the quantity of heat generated from the motor. Then, Trip is generated when overcurrent continues, exceeding the operating time (O-Time).

Stall/Locked Rotor

It is a function to prevent burning caused by locked rotor, startup failure and startup delay. When the level of load current increases due to overheating and overcurrent during operation or when the load torque exceeds the motor torque, such failure is detected to break the related circuits.

Phase Fail/Phase Unbalance

When phase fail occurs, a motor may not start to operate and the motor under operation will stop owing to the lack of torque or reverse phase current will continue to flow, generating heat. DMPi calculates the unbalance of three-phase current and when it reaches

100%, it operates at 3sec as phase fail. It can be set for tripping at 5sec when the phase unbalance in within 10~90%.

*Delay time may be set within the range of 0~200sec so that it does not function upon startup.

Reverse Phase

It is a function to prevent reversing of a motor. The phase difference of three-phase current is compared for operation within 0.1~1.0sec when the phase sequence has changed.

Reverse phase is checked only upon motor startup.

Under Current Protection

This equipment is mainly used to monitor no-load status caused by the separation or damage of the drive shaft of a motor, or to protect the idle rotation (no-load) status of pump. It is possible to set up 30~70% of rated current. At the time of third second, it runs.

Ground Fault

Ground fault leakage current is detected to prevent ground faults arising from electric leakage and secondary accidents (Phase faults and electric shock accidents). Current sensitivity and operating time are set differently according to the grounded system or purpose of protection. Current sensitivity can be set within the range of 30mA~3A and the operating time within the range of 0.05~5.0sec.

* Delay time may be set within the range of 0~200sec so that it does not function upon startup,

and built-in ZCT is provided according to the Type.

Instance

It is a function to protect a motor from short-circuit current. It operates within 50ms when fault current of more than 500~1500% is generated. Delay time may be set within the range of 0~200sec so that it does not function upon startup.

which is displayed in the following order: hour/minute.

Note) The total operating time is saved every 10 minutes. When turned off, any value less than 10 minutes will be reset.

6. Heat quantity reset (The motor’s heat quantity is reset by force to switch to the cold mode.)

1) When the operating characteristics of A Group 2.CHA are set in the thermal heat build-up mode (th)

2) When the Test/Reset key is pressed under overload trip to return and then a motor is driven right away, the motor will be hot.

Thus, trip is immediately performed.

3) On the other hand, when the Enter + Test / Reset keys are pressed simultaneously under overcurrent trip to return

and then a motor is driven right away, the motor will be cold. Thus, trip will be executed after the set time.

Inverse time characteristic

1. Check the rated voltage and apply the control

power to A1 and A2 terminal

If 220V power is supplied to a model for AC110V, overvoltage occurs and thereby EMPR has a failure.

RC (A) Knob

O.L LED (2CT) O.L/Fault LED (3CT)

Test/Reset button

Time Knob

2.

With Test/Reset button, check that output contact works normally.

1) If Test/Reset button is clicked once, O.L (display lamp) representing Trip is turned on. If EMPR is Tripped, output contact works.

2) If Test/Reset button is clicked again at the time of EMPR Trip, the display lamp is turned off and the equipment resets to its original state.

3) Auto reset function (Auto Reset)

• In case of overcurrent Trip, the equipment automatically returns after one minute (GMP22-2PA/GMP40-2PA),

• In case of overcurrent Trip, the equipment automatically returns after 0~120 seconds (variable setting) (GMP60T-A).

Note) To prevent a Trip accident, Test/Reset button is designed not to work while a motor is running.

3 .

Set the operating time

An operating time is based on 600% of rated current in the characteristic curve.

1) Set up the position of operating time control knob (Time Knob) in consideration of a staring time and starting current.

(E.g., on the assumption that a starting current accounts for 600%of normal operating current and a staring time is 10 seconds, set Time Knob to about 11~12 seconds with 10-20% margin.)

2) An available operating time ranges from 0 to 30 seconds.

3) In case that Time Knob is set to 10 seconds, if the starting current or 600% of rated current is supplied for 10 seconds, immediate Trip occurs.

Note) For a motor with frequent forward/reverse starting, such as a motor of crane or hoist, an EMPR with the characteristic of definite time is recommended

4 . Set up a rated current.

Setting is based on the rated current of a motor (normal operating current).

1) Check that a motor’s rated current is within the current control range of EMPR.

2) Set RC (Rating Current) Knob up to the maximum and run the motor.

3) In normal operation state, slowly turn RC Knob counter clockwise and stop at the point that overcurrent display lamp (O.L) flickers. At this point, the actual load current value

Check status of operation by LED

2CT : Overcurrent, Phase failure, Lock/Stall

3CT : Overcurrent, Phase failure, Reverse phase, Phase unbalance, Lock/Stall

1) In case of overcurrent

• If there will be an overcurrent during motor operation, the red color of LED will flicker at 0.4 second intervals.

After tripping because of overcurrent, the red color of LED will light up.

2) In case of phase failure (2CT EMPR can protect motor from R or T phase failure.)

• If a motor stops running due to phase failure, stall current flows. As a result, it is possible to protect the motor against overcurrent.

If the motor keeps running in phase failure, it is necessary to protect against phase failure.

• If phase failure occurs in three-phase load (3CT), Trip occurs within three seconds. (O.L LED is turned on)

R-phase phase failure - Fault LED flickers once (0.4 second) at an interval of three seconds.

S-phase phase failure - Fault LED flickers twice at an interval of three seconds.

T-phase phase failure - Fault LED flickers three times at an interval of three seconds

3) In case of phase unbalance

• If phase unbalance factor of three phase is about 50% or more after its calculation, Fault LED only flickers at an interval of 0.4 second

and then trips after five seconds. (After Trip, the same display as phase failure appears.)

4) In case of Reverse phase

• Trip occurs within 1 second, and the lamp flickers red and green in turn (GMP22/40/60-R type) or O.L LED and Fault LED flicker (GMP80-3SR).

In this case, to detect reverse phase, a load current should be more than the minimum current setting range of EMPR.

EMPR has a failure.

2. Check the Test/Reset button operation

D-Time knob RC (A) knob time(%)

1) If Test/Reset button is clicked once, O.L

(display lamp) is turned on, EMPR is

Tripped, and output contact runs.

2) If Test/Reset Button is clicked once again when EMPR is Tripped, the display lamp is turned off and the equipment returns to its original state

(Reset).

Note) 1. To prevent a Trip accident, Test/Reset button is designed not to work while a motor is running. 2. If Test/Reset button is clicked twice within 0.5 second, it is possible to check the final failure cause.

3. Set the operating time

D-Time (Delay Time) : 0~30 sec

It refers to the time of delaying EMPR operation in order to prevent Trip from a motor’s staring current.

1) With the use of D-Time Knob, set up a delay time taken from motor starting to normal running current.

2) If you are unaware of a start delay time, set it to the maximum time and measure how long it takes to reach the normal starting current of the motor, and then set it up again. (Reference: in case of general load, set it to about 3~5 seconds.)

Note) If actual load current fails to detect during a set time, a motor can be damaged. Set up a delay time rightly.

O-Time (Operating Time) : 0~15 sec

It refers to the time taken from the start of overcurrent to EMPR Trip. After the set O-Time, EMPR is Tripped.

1) With the use of O-Time Knob, set up an operating time.

2) If O-Time is the minimum value, EMPR is immediately tripped as soon as overload occurs. (Reference: generally, set it to 4~6 seconds.)

A-Time (Auto Reset Time): 0~120 seconds; set up an automatic reset time in auto reset type.

4.

Set the operating current

Setting is based on the rated current of a motor (normal operating current).

1) Check that a motor’s rated current is within the current control range of EMPR.

2) Set RC (Rating Current) Knob up to the maximum and run the motor.

3) In normal operation state, slowly turn RC Knob counter clockwise and stop at the point that overcurrent display lamp (O.L) flickers. At this point, the actual load current value (100%) of the motor is displayed.

4) From the point, turn RC Knob clockwise. Set up the knob at this point that O.L lamp is turned off (less than motor full load current).

Generally, set it to 110~120% of actual load current (set to a value lower than a motor full load current).

Overcurrent-51

By setting up an operating time in the 1-60 seconds unit on the basis of 6005 of rated current in consideration of a motor’s starting time, it is possible to configure the overload characteristic curve of Class 1-60.

If Definite Time Characteristic is selected, the equipment starts to detect overcurrent after the set operating delay time (D-Time) regardless of a motor’s generated heat. If overcurrent continues to be supplied after an operating time (O-Time), Trip occurs.

<Inverse Time Characteristic> <Definite Time Characteristic>

Stall/Locked Rotor-48/51LR

This function is used to prevent the loss and damage made by a motor’s rotor stall, starting failure, and staring delay, and to detect an increased load current by overheat overload in operation or the case that load torque exceeds motor torque in order to block a circuit. Overcurrent function by starting current works after a set delay time

Under Current-37

This function is used to monitor the no-load caused by the separation or damage of a motor’s drive shaft, or to prevent a pump’s idle rotation (no-load). It is possible to set up to

30~70% of rated current. It works within three seconds.

Phase Fail/Phase Unbalance-47P

If phase failure occurs, a motor fails to start. A motor in operation stops due to shortage of torque or has overheat due to continuous reverse phase current.

IMP calculates phase unbalance of three-phase current. It is possible to select one of the two cases: if the calculated result is 70% or more, this function is executed within 1.5 seconds; if phase unbalance factor is 10-70%, trip occurs within three seconds.

* In a single-phase motor, turn OFF phase fail and phase unbalance protection function.

Reverse Phase

This function is used to prevent a motor’s reverse rotation. After the phase difference of three-phase current inputs is compared, this function is executed within 0.1 second if the phase sequence changes. Reverse phase is checked only if a motor starts up.

In a single-phase motor, turn OFF this function.

Ground Fault-51G

This function is used to detect ground fault leakage current. In other words, it aims to prevent leakage-induced ground fault and secondary accidents (short circuit and electric shock).

It is possible to set up a current sensitivity and an operating time differently depending on grounding system or protection purpose.

It is possible to set a current sensitivity to 30mA~25A and an operating time to 0.05~1.0 second.

8.Analog (DC 4~20mA) Output

1) The biggest current out of measured 3-phase currents is converted into DC 4mA~20mA and the current measured remotely by digital meter can be displayed.

2) When there is no current, 4mA is sent. If the current goes beyond the predefined value, 20mA is sent.

20mA

16mA

13.6mA

12mA from 3A. Thus, when the current is under 0.3A (3A), 0A is measured and output is 4mA. (To measure the load current correctly, an appropriate CT should be used).

Current protection

Over Current

The device provides overcurrent protection either with inverse-time or with definite-time element.

1) Inverse-time delay curve

The trip time decreases as the overcurrent increases in an inversetime curve.

Inverse-time delay curve

MMP Series

2) Definite-time delay curve

The operating time is unaffected by the magnitude of the overcurrent.

Definite-time delay curve

Stall/Locked Rotor

Stall activates when the motor is unable to rotate due to any externally mechanical obstruction, and Lock activates due to internal issue of the motor.


The motor is unable to start under phase loss. If it occurs while the motor is running it causes motor stopping by lack of torque, or significant rotor heating by reverse current. The S-EMPR calculates the percent three-phase unbalance current. If it exceeds 70%, which is determined to be phase loss, the device trips within 1.5 sec. If it is between 10 to 70% the device trips within3 sec. This function is disabled for a single-phase mode.

Reverse Phase

This protection is for preventing the motor from reverse rotation. The device detects motor phase rotation and trips within 0.1 sec. if phase sequence is incorrect. It detects when the motor is starting.

* This function is disabled for a single-phase mode.

Under Current

If the real load current falls below the warning or trip level for longer than the time-delay setting, the device can issue a warning or trip signal.

Ground fault protection

Ground Fault

Stall activates when the motor is unable to rotate due to any externally mechanical obstruction, and Lock activates due to internal issue of the motor.

Zero-phase ground current

ZCT in or out of the product is used to detect zero current flowing in three phases.

Selective Ground Fault

If a non-grounding system has ground fault, the current over the zero current transformer of each distribution line flows from the load side to the power side in a good line, and from the power side to the load side in a bad line. This protection function is able to select and block a bad line by determining the direction of failure current on the basis of the zero voltage.

Instance

While an AC motor is running, if an actual load current value is higher than an set value of instantaneous current, Trip occurs in

50msec.

As shown the figure, the bad line (Feeder1) and the good line has an opposite current direction. With the use of this current direction, it is possible to select one. If another line has a failure, the charging current of the line flows in an opposite direction from the current flowing at the time of the accident.

Therefore, it does not run.

In a non-grounding system, the ground fault current is the sum of the line charging current and the limiting-resistance current. Since it is relatively small, zero CT(ZCT) is needed. This product has ZCT built in so that it is possible to make a system simply.

Voltage & Power Protection

Over Current

Overvoltage protection detects the voltage levels and operates if they are greater than the setting to protect the sensitive loads or circuits against such condition.

Under Voltage

If the voltage levels fall below the setting the Undervoltage protection issues a warning or trip signal to protect the sensitive loads such as a inductive motor.


This protection operates if the percent phase-to-phase voltage unbalance is greater than the setting.

Used to prevent an excessive vibration of three-phase induction motor and a damage of the stator and rotor windings.

This function is disabled under a single-phase mode.

Reverse Phase

This protection operates if the percent phase reversal voltage is greater than the setting.

It detects when the motor is starting. This function is disabled for a single-phase mode.

Over Power

The overpower element operates if the three-phase active power exceeds the setting level.

This element can be used to prevent the power from entering the generator before disconnecting from the system when the generator operation is finished.

Under Power

The underpower element operates if the three-phase active power falls below the setting level.

Over Power Factor

The over power factor element operates if the power factor exceeds the setting level.

If the load is very small, especially for no-load the capacitive current may flow due to overcapacity of the capacitor in line, which causes the power loss of the line and transformer, and electric stress on motors. This element can be used to protect against such current.

Under Power Factor

The under power factor element operates if the power factor falls below the setting level.

If the power factor of a customer falls below that of a generator in a power plant the generator current increases over the rated current or the power output is limited. For this reason, the power factor of a customer is regulated.

In addition, the under power factor causes the increase of the input current which prevents the temperature rise in cables, transformers and motors.

Analog (4~20mA) output function

Specification

• This function measures the maximum out of the 3-phase currents and converts it into

DC 4~20mA for output, which can be converted back to the original value by a digital meter.

• 20mA Output Settings : 0.5~10A or 5~100A

Note) 1. In the 0.5~10A setting mode the device starts to measure from 0.15A, which means the current 0.15A or less is measured as 0A and the output becomes 4mA.

(0.15A when one> 4mA is being a real measurement)

2. Accuracy at 25°C : : ± 0.15% / ℃

• During stopping : 4mA

• Rated setting value or more : 20mA

• Load : 500Ω or less

Note) The allowable burden of cable must be less than 500Ω.Shielded cables are recommended in consideration of the resistance

of the receiving meter (typically 250Ω) and the line resistance.

*Attention in panel design

1. It is required to have grounding connection with all equipment.

2. It is required to minimize wiring as most as possible.

3. After a shield-type cable is applied, it is required to ground the shield.

*If induced voltage occurs

1. It is required to add a proper capacitor in parallel depending on the parasitic capacitance of product input part.

2. If induced voltage occurs even after the capacitor is added,

it is required to get auxiliary relay energyed in order for an input to make possible through an auxiliary contact point when a circuit is designed.
