RM3JA2 Current Measurement Relays

Operating Principles

RM3JA2

This device is used anywhere it is important to detect when a preset a.c. or d.c. current threshold is exceeded. This relay can be used to monitor currents between 3mA and 1A. Some examples of applications for this relay are:

— To detect whether a conveyor is loaded or not.

— To detect a load on a pump.

— To detect a fan belt breaking.

— To monitor loading of single phase motors.

— To monitor heating and lighting circuits.

Operating principles

• Apply the appropriate supply voltage (U supply) to terminals A1 and A2. This supplies power to the electronics inside this device.

• The current to be monitored is connected to terminal B1 or B2 or B3 (depending on current to be monitored) and terminal C.

• The output relay terminal (15-common, 16-normally close contact, 18-normally open contact) is used to signal that the current is or is not above the preset current threshold setting.

• The current threshold setting (IS1)(refer to the diagrams below) is set to the current above which it is desired to have the output relays change state.

• The hysteresis needs to be set. Hysteresis is the difference between the current threshold setting and the dropout current setting (IS2) of the output relay. It is expressed as a percentage: h= (IS1 — IS2)/IS1

RM3 JA2

2 Current threshold setting (IS1)

If the current to be monitored is connected to:

• B1 and C = Use the white scale times 0.001

(3 to 30mA)

• B2 and C = Use the yellow scale times 0.001

(10 to 100mA)

• B3 and C = Use the yellow scale times 0.01

(0.1 to 1A)

R The yellow LED labeled with an R indicates that the output contacts have been energized when it is illuminated.

U The green LED labeled with a U (Voltage) indicates that supply voltage is present to the RM3 relay when illuminated.

Load

• If the supply voltage (U supply) is not applied to terminals A1 and A2, the output relays will be in its deenergized state

(contact 15-16 will be closed and contact 15-18 will be open).

• When supply voltage is applied to terminal A1 and A2, the output relay will not change state until the current has exceeded the current threshold setting (IS1) and the current remains above the current threshold setting (IS1) level for more than the measuring cycle of

≤

80 milliseconds.

• After the output relay has changed state, it will remain energized unless the current falls below the dropout current setting (current threshold setting minus the hysteresis) or supply voltage is lost from terminals A1 or A2 or the measured current exceeds the upper limits of the RM3 relay, which results in damage to the RM3 relay.

• The measure range of this relay can be extended by:

— Using a current transformer and connecting the secondary to the terminals on the RM3 relay.

— Connecting a resistor in parallel with the measuring input (see the next page for an example).

• Using page 8, an RM3JA211FG7 relay would be selected because of the

120 Vac supply voltage and it has a measurement range of 3mA to 1A.

• Wire the RM3JA211FG7 relay as explained under operating principles on the previous page.

• Set the current threshold potentiometer (2) to 80 on the yellow scale. Current is being measured on terminals B3 and C, which means you use the yellow scale times 0.01 (80×0.01=0.8A).

• Set the hysteresis potentiometer to 25 h = (IS1-IS2)/IS1

(0.8-0.6)/0.8=0.25 or 25%

• Example of extending the measuring range

Operating Principles

RM3JA1

This device is designed to detect when a preset current threshold is exceeded, on a.c. or d.c. supply. The RM3JA1••MW relay can monitor overcurrent or undercurrent. All the other relays can only monitor overcurrent. These relays can be used to monitor currents between 3 mA to 15 A.

Some examples of applications for these relays are:

— To detect whether a conveyor is loaded or not

— To detect a load on a pump

— To detect a fan belt breaking

— To monitor the loading of a single phase motor

— To monitor heating and lighting loads

Operating principles

•

Apply the appropriate supply voltage (U Supply) to terminals A1 and A2. This supplies power to the electronics inside the device.

•

The current to be monitored is connected to terminal B1 or B2 or B3, depending on current to be monitored, and terminal C.

•

The output relay terminals (15 and 25 -Common, 16 and 26 -Normally closed contact, and 18 and 28- Normally open contact) are used to signal that the current is or is not above the preset current threshold setting.

•

The current threshold setting (IS1) (refer to the diagram below) is set to the current above which it is desired to have the output relays change state.

•

The hysteresis needs to be set. Hysteresis is the difference between the current threshold setting and the dropout current setting (IS2) of the output relays. It is expressed as a percentage: h = (IS1-IS2)/IS1. Hysteresis is adjustable between 5 and 30%.

If the current to be monitored is connected to:

• B1 and C = Use the yellow scale times 0.1

••

MW relay.

R The yellow LED labeled with an R indicates that the output contacts have been energized when it is illuminated.

U The green LED labeled with a U (voltage) indicates that supply voltage is present to the RM3 relay when illuminated.

Functional diagram

• If the supply voltage (U supply) is not applied to terminals A1 and A2, the output relays will be in the de-energized state (Contacts 15-16 and 25-26 will be closed and contacts 15-18 and 25-28 will be open).

• If the RM3JA1••MW set to OC or any of the other RM3JA1 relays monitors a current greater than the threshold setting

(IS1), the output relay will energize with or without time delay, depending on the relay chosen. When the current returns to a value IS2 below the threshold, depending on the hysteresis setting, the relay is instantaneously deenergized.

• If the RM3JA1••MW relay set to UC monitors a current less than the threshold setting IS1, the output relay will energize with or without time delay, depending on the relay chosen. When the current returns to a value IS2 above the threshold, depending on the hysteresis setting, the relay is instantaneously de-energized.

• A measuring cycle lasts only 80 ms, which allows rapid detection of changes in current.

RM3UA2 Voltage Measurement Relays

Operating Principles

RM3UA2

This device is designed to detect when a preset voltage threshold is exceeded, on a.c. or d.c.

Monitoring is on overvoltage, within a measurement range of 50 mV to 500 V.

Some examples of applications for these relays are:

— d.c. motor overspeed control,

— battery monitoring,

— monitoring of a.c. or d.c. supplies.

Operating principles

• Apply the appropriate supply voltage (U Supply) to terminals A1 and A2. This supplies power to the electronics inside this device.

• The voltage to be monitored is connected to terminals B1 or B2 or B3 (Depending on the voltage to be monitored.)

and C.

• The output relay terminals (15 — Common, 16 — Normally closed contact, 18 — Normally open contact) is used to signal that the voltage is or is not above the preset voltage threshold setting.

• The voltage threshold setting (US1) (refer to the diagram below) is set to the voltage above which it is desired to have the output relays change state.

• The hysteresis needs to be set. The hysteresis is the difference between the voltage threshold setting and the dropout voltage setting (US2) of the output relays. It is expressed as a percentage: h= (US1/US2)/US1. Hysteresis is adjustable between 5 and 30%.

R The yellow LED labeled with an R indicates that the output contact has been energized when it is illuminated.

U The green LED labeled with a U (Voltage) Indicates that supply voltage is present to the RM3 relay when illuminated.

Functional diagram

•

If the supply voltage is not applied to terminals A1 and A2, the output relays will be in the deenergized state (Contacts

15-16 will be closed and contacts 15-18 will be open).

The voltage to be monitored is connected to terminals B1, B2 or B3 and C.

•

When supply voltage is applied to terminal A1 and A2, the output relay will not change state until the voltage has exceeded the voltage threshold setting (US1) and the voltage remains above the voltage threshold setting (US1) level for more than the measuring cycle of <80 milliseconds.

•

After the output relay has changed state, it will remain energized unless the voltage falls below the dropout voltage setting (voltage threshold setting minus the hysteresis) or the supply voltage is lost from terminals A1 and A2 or the measured voltage exceeds the upper limits of the RM3 relay, which results in damage to the RM3 relay.

Operating Principles

RM3UA1

This device is designed to detect when a preset voltage threshold is exceeded, on a.c. or d.c. supply. Monitoring is on overvoltage or undervoltage, within a measurement range of 50 mV to 500 V.

Applications :

— d.c. motor overspeed control,

— battery monitoring,

— monitoring of a.c. or d.c. supplies.

Operating principles

• Apply the appropriate supply voltage (U Supply) to terminals A1 and A2. This supplies power to the electronics inside this device.

• The voltage to be monitored is connected to terminals B1 or B2 or B3 (Depending on the voltage to be monitored.) and C.

• The output relay terminals (15 & 25 — Commons, 16 & 26 — Normally closed contacts, 18 & 28 — Normally open contacts) are used to signal that the voltage is or is not above the preset voltage threshold setting.

• Relay set for overvoltage detection (OV) :

If the voltage is greater than the threshold setting US1, the output relay is energized with or without time delay. When the voltage returns to a value US2 below the threshold, depending on the hysteresis setting, the relay is instantaneously de-energized.

• Relay set for undervoltage detection (UV) :

If the voltage is less than the threshold setting US1, the output relay is energized with or without time delay. When the voltage returns to a value US2 above the threshold, depending on the hysteresis setting, the relay is deenergized.

• The hysteresis needs to be set . The hysteresis is the difference between the voltage threshold setting and the dropout voltage setting (US2) of the output relays. It is expressed as a percentage: h= (US1/US2)/US1. Hysteresis is adjustable between 5 and 30 %.

• A measuring cycle lasts only 80 ms, which allows rapid detection of changes in voltage.

RM3 Specialty Relays

RM3TG2 3-Phase Supply Relays

Operating Principles

RM3TG2

This device monitors the presence and rotational direction of the phases in a 3-phase supply under no-load condition.

Applications:

• Connection of moving equipment :

— site equipment (cranes, pumps, conveyors, etc.),

— agricultural equipment,

— refrigerated trucks.

• Protection of persons and equipment against the consequences of reverse running:

— lifting, handling, elevators, escalators, etc.

• Control of sensitive 3-phase supplies.

Operating principle

The voltage of the supply to be monitored, connected to terminals L1, L2, L3 of the relay, also provides its power supply.

In normal operation, the output relay is energized, the yellow LED is on. If a fault occurs — reversal in rotational direction of phases, failure of one or more phases — the relay is de-energized (or cannot energize at switch-on) and the yellow LED goes out.

This relay is specifically designed for control of supplies under no-load conditions.

In the case of a supply under load, a return voltage can be registered by the RM3 in spite of a phase failure, thereby preventing detection of the true fault (phase failure detection threshold U < 60 V).

For control of supplies under load, select an RM3TR or TAR1.

This multifunction device is designed to monitor the presence and rotational direction of the phases in a three-phase supply, as well as overvoltage (U > Un) or undervoltage (U < Un).

Applications

• Connection of moving equipment:

— site equipment (cranes, pumps, conveyors, etc.),

— agricultural equipment,

— refrigerated trucks.

• Protection of persons and equipment against the consequences of reverse running:

— lifting, handling, elevators, escalators, etc.

Operating principles

The control circuit supply voltage (Usupply) is applied to terminals A1-A2.

Monitoring of the 3-phase supply (Un) is performed on terminals L1, L2, L3.

In normal operation, the output relay is energized, the yellow LED is on.

The output relay is de-energized and the yellow LED goes out if any of the following faults are detected:

• Overvoltage or undervoltage

If the voltage goes outside the range of Un, the output relay is de-energized:

— overvoltage: the red LED > U illuminates,

— undervoltage: the red LED < U illuminates.

When the supply returns to its rated value, the relay is reenergized according to the hysteresis value (5 %) and the corresponding indicator goes out.

A selector switch allows selection of an adjustable 0.1 to 10 second time delay. With function ,this delay will allow the relay to ignore transient “over” and “under” voltages that might occur. With function , all transients above and below are taken into account and re-energization of the relay is delayed.

• Phase failure or incorrect rotational direction of phases

The output relay is de-energized without a time delay in the event of a phase failure or incorrect rotational direction of phases, the red LED “P” illuminates.

The output relay is energized and the fault indicator goes out as soon as the 3-phase supply (Un) returns to normal, (function ) or after a preset time delay, (function ).

Setup information

If the supply voltage (Un) is coming from the 3-phase voltage to be monitored, connect A1 to L1, and A2 to L3. When this is done, some faults cannot be displayed: failure of phase L1 or L3 for example.

Example of undervoltage and overvoltage to be monitored :

— Nominal 3-phase voltage to be monitored 480 Vac 60 Hz

— Overvoltage threshold to be monitored : 500 Vac

— Undervoltage threshold to be monitored : 400 Vac

— Control circuit voltage : 480 Vac

• Using page 28, an RM3TR114VS7 relay would be selected.

• Wire the RM3TR114VS7 relay as explained under operating principles on the previous page.

• Connect the 3-phase voltage to be monitored to terminals L1, L2, L3.

• Adjust the overvoltage to be monitored to 500 V by means of potentiometer 3.

• Adjust the undervoltage to be monitored to 400 V by means of potentiometer 4.

RM3TA2 3-Phase Supply Relay

Operating Principles

RM3TA2

This device detects:

• A phase imbalance (asymmetry fault) within an adjustable threshold from 5 to 15 % (reduction or increase in voltage of one phase in relation to the other two).

• Failure of one or more phases.

• A phase reversal (Rotational direction of phases fault).

Applications:

• Connection of moving equipment:

— site equipment (cranes, pumps, conveyors, etc.),

— agricultural equipment,

— refrigerated trucks.

• Protection of motors against single-phase operation.

• Control of sensitive 3-phase supplies.

Operating principle

The supply voltage to be monitored is connected to terminals L1, L2, L3 of the relay, it also provides the power for the relay to operate.

In normal operation, the output relay is energized and the yellow LED is on.

When a phase imbalance (asymmetry fault), phase failure or phase reversal (rotational direction fault) is detected, the output relay de-energizes after a fixed time delay of 0.5 seconds (or cannot energize at start up), and the yellow LED goes out.

A fixed hysteresis (1) of 20 % is built-into the relay.

— relay re-energization threshold: 432 V + (20 % x 10 %) of 432 V = 440.6 V.

RM3 Specialty Relays

RM3LG2 Liquid Level Control Relay

Operating Principles

RM3LG2

This device monitors the levels of conductive liquids. Do not use with flammable liquids.

It controls the actuation of pumps or valves to regulate the levels and is also suitable for protecting submersible pumps against running empty, or protecting tanks from “overflow”. It can also be used to control dosing of liquids in mixing processes.

• Some examples of liquids in which the RM3LG2 relay can be used:

— spring, town, industrial and sea water

— metallic, acid or basic salt solutions

— liquid fertilizers

— non concentrated alcohol (< 40 %)

— liquids in the food processing industry: milk, beer, coffee, etc.

• Some examples of liquids in which the RM3LG2 relay CAN NOT be used:

— chemically pure water

— fuels, liquid gasses (flammable)

— oil, concentrated alcohol (> 40 %)

— ethylene, glycol, paraffin, varnish and paints

Presentation

RM3 LG2

Response sensitivity potentiometer (in kW).

The yellow LED labeled with an R indicates that the output relays have been energized when it is illuminated.

The green LED labeled with a U (Supply voltage) indicates that supply voltage is present to the RM3 relay when illuminated.

Operating principle

The operating principle is based on a change in the resistance measured between immersed or non immersed electrodes.

The electrodes may be replaced by other sensors or probes which transmit values representing variations in resistance

(Refer to page 39, “Setting-up”).

• 3 electrodes (1)

Note: If a metallic tank is used, the ground electrode (B1) can be eliminated by connecting the cable directly to one of the tank’s metallic surfaces.

(1) This product can be used with only 2 electrodes.

In this case, electrode B2 performs both the high level and low level functions. The absence of a time delay can cause oscillation of the output relay (wave effect).

Level electrode

Reference electrode

(skirt)

Set the potentiometer to the minimum value.

Connect the electrodes as shown below.

Apply power to terminals A1 and A2.

When all the electrodes are simultaneously immersed in the liquid to be monitored, slowly turn the potentiometer towards the maximum value (100 W) until the relay is energized. Exceed the tripping threshold of the relay by 10 kW to compensate for variations in the supply voltage. (The relay may already be energized before turning the potentiometer). If the relay will not energize, a more sensitive device must be used (greater ohmic value): see RM3LA1.

Then check that the relay de-energizes correctly as soon as electrodes EH and EB are out of the liquid (see examples below). If the relay does not de-energize, select a less sensitive device (see RM3LA1).

The electrode connection point must be protected against corrosion, by sticking or sealing. In areas where thunderstorms are likely to occur, measures must also be taken to protect the electrode lines.

Probe LA9RM201

This probe is of the “suspended” type. It is coaxial; i.e. in addition to the normal (central) electrode, the stainless steel skirt can also act as ground (reference) electrode, which means that there is no need to install a separate reference probe. In this way, for controlling one level, only one probe is required instead of 2; for controlling 2 levels, only 2 probes are required instead of 3.

The connecting cable must be of the “2-conductor” type with common cylindrical PVC sheath, having a maximum diameter of 6.3 mm. The skirt also acts as a “calming chamber”, so avoiding inaccuracy due to an agitated surface of the liquid (waves).

Maximum operating temperature: 212

Set potentiometers 4 and 2 to the minimum value and set switch 3 to 5 k.

Connect the electrodes as shown below.

Apply power to terminals A1 and A2.

When all the electrodes are simultaneously immersed in the liquid to be monitored, slowly turn the sensitivity potentiometer 4 towards the maximum value (50) until the relay is energized. (The relay may energize before turning the potentiometer. If it does you are finished with this step.). If the relay will not energize, set potentiometer 4 back to its minimum setting and turn switch 3 to 50k and repeat the above procedure. If the relay still doesn’t energize, set potentiometer 4 back to its minimum setting again and turn switch 3 to 500k and repeat the above procedure. If the relay still doesn’t energize, this relay will not work for the application.

Then make sure the relay de-energizes correctly when electrodes EH and EB are removed from the liquid.

Note : The maximum level EH on a time delay on filling application can be raised by means of the adjustable time delay from 0.1 to 10 seconds, using function . The minimum level EB on a time delay on emptying application can be lowered by means of the adjustment delay from 0.1 to 10 seconds, using function .

The electrode connection point must be sealed to protect against corrosion. In areas where thunderstorms are likely to occur, the electrode lines must be protected.

Probe LA9RM201

This probe is of the “suspended” type. It is coaxial ; i.e. in addition to the normal (central) electrode, the stainless steel skirt can also act as ground (reference) electrode, which means that there is no need to install a separate reference probe. In this way, for controlling one level, only one probe is required instead of 2 ; for controlling 2 levels, only 2 probes are required instead of 3.

RM3PA1 Insulation Control Relay

Operating Principles

RM3PA1

This device monitors the presence of an insulation resistance on an a.c. supply (with neutral insulated from ground) and the ground connection.

• The RM3PA1 insulation control relay is only for equipment monitoring and should not be

used for personnel electrical protection.

Its detection threshold range is 1 to 110 kW.

A fault memory is possible (automatic or manual, local or remote reset), refer to page 47 “Setting-up”.

A pushbutton on the front face of the relay allows an “ground fault” TEST to be performed. This test can also be performed remotely, the LED on the front of the relay indicates the various states, refer to page 47 “Setting-up”.

Applications on a.c. supply

3-phase supplies : Single-phase supplies :

— without neutral conductor, — control circuit of automation equipment,

— with artificial neutral, — control circuit,

— with insulated neutral. — any auxiliary control circuit galvanically isolated from the mains supply.

The red LED labeled with a F indicates that the output relay has been energized when it is illuminated.

The green LED labeled with a U (Supply Voltage) indicates that supply voltage is present to the RM3 relay when illuminated.

Operating principle

The supply voltage is connected to terminals A1-A2 or A1-B2. Its value can be identical to that of the supply to be monitored.

A continuous voltage (Terminal L) is connected between one phase (or neutral if present) of the installation and ground

(s terminal).

As soon as a ground insulation fault occurs, it causes a non infinite resistance to appear between the installation and ground. A fault current is established and this current then passes through the so-called “insulation” resistance.

RM3-PA1

–

When this current exceeds a value corresponding to the preset threshold resistance, the output relay is energized with a time delay (refer to curve on page 47 “Setting-up”) and a fault indicator illuminates on the relay.

Purpose of continuous insulation monitor RM3PA1

The main purpose of this device is to indicate the first insulation fault in an installation in order to protect it against incorrect operation due to the appearance of a second fault.

On the figure to the left, resistances R1 and R2, corresponding to two successive insulation faults, are in series and can keep K2 energized when contact K1 is open.

This incorrect operation can have very serious consequences in some installations.

Setup information

Fault memory

Short-circuiting of terminals S1 and S2 (see scheme to the right) allows the fault to be memorized as soon as it appears, even if only briefly. The duration of the fault must exceed the response time of the relay (see curve below) for it to be detected.

If this short-circuiting is achieved by means of a N/C pushbutton, this acts as the remote reset button (if the fault has disappeared). Manual local resetting is achieved by briefly pressing (less than 0.5 s) the RESET/TEST button on the front of the relay.

Test

When the installation being controlled does not have an insulation fault, pressing the RESET/TEST button on the relay causes 2 simultaneous actions:

— the measuring input terminal not connected to ground (L) is disconnected from the line being controlled,

— a resistance (internal) of 820 W is connected to this input in order to simulate an insulation fault.

The relay must then react in the same way as for a real fault.

A N/O pushbutton may be connected to terminals S1 and s which will act as the remote test button and which will have the same effect as the built-in test button

(See scheme to the right).

Это устройство не может создавать вредные помехи.
Это устройство должно принимать любые помехи, включая помехи, которые могут вызвать сбои в работе.

Любые изменения или модификации, прямо не одобренные стороной, ответственной за соответствие, могут лишить пользователя права на эксплуатацию оборудования.

Это оборудование было протестировано и признано соответствующим ограничениям для цифровых устройств класса B в соответствии с частью 15 правил FCC. Эти ограничения разработаны для обеспечения разумной защиты от вредных помех при установке в жилых помещениях. Это оборудование генерирует, использует и может излучать радиочастотную энергию и, если оно установлено и используется не в соответствии с инструкциями, может создавать вредные помехи для радиосвязи. Однако нет гарантии, что помехи не возникнут при конкретной установке. Если это оборудование действительно создает недопустимые помехи для приема радио или телевидения, что можно определить путем включения и выключения оборудования, пользователю рекомендуется попытаться устранить помехи одним или несколькими из следующих способов:

Изменить ориентацию или местоположение приемной антенны.
Увеличьте расстояние между оборудованием и приемником.
Подключить оборудование к розетке в цепи, отличной от той, к которой подключен приемник.
Обратитесь за помощью к дилеру или опытному радио / телевизионному технику.

Устройство было проверено на соответствие общим требованиям к воздействию радиочастотного излучения. Устройство можно использовать в условиях переносного воздействия без ограничений.
