3-phase supply control relays RM17TG

RM17TGp0

Product description


RM17TGp0 measurement and control relays are for monitoring of 3-phase supplies and the correct sequencing of phases L1, L2 and L3, as well as the total loss of one or more of these phases.

These control relays accept different nominal 3-phase voltage values:

•

208

–

480 Vac for RM17TG00

•

208

–

440 Vac for RM17TG20

They monitor their own power supply, measured as a true rms value.

Relay status is indicated by an LED.

•

When relay is energized, LED is illuminated.

•

When relay is not energized, LED is not illuminated.

The relays are designed for clip-on mounting on 5 rail.

Applications

•

Control of moving equipment (site equipment, agricultural equipment, refrigerated trucks)

•

Control for protection of people and equipment against the consequences of reverse running (lifting, handling, elevators, escalators, etc.)

•

Control of sensitive 3-phase supplies

•

Protection against the risk of a driving load (phase failure/back EMF)

•

Normal/emergency power supply switching

Operating principle

Zelio

3-phase supply control relays monitor:

•

Correct sequencing of phases L1, L2 and L3

Fault signalling is by LED.

Phase control relays: RM17TGp0

The relay monitors its own power supply.

The relay monitors:

•

Correct sequencing of the three phases

•

Total loss of one or more of the phases

When phase sequence and voltages are correct (> 183 Vac), the output relay(s) is/are closed and the yellow LED is on.

In the event of a sequencing fault or total loss of one or more phases

(detected as soon as one of the voltages drops below 100 Vac) the relay opens instantly and the LED goes out.

When the fault is cleared, the output relay re-energizes instantaneously.

On energization of the device with a fault measured, the relay stays open.

•

Fault signalling is by LED

■

Voltage selector switch:

•

Set the switch to the 3-phase supply voltage Un.

•

The position of this switch is only taken into account on energization of the device.

•

If the switch position is changed while the device is operating, all the

LEDs flash, but the product continues to operate normally with the voltage selected at the time of energization preceding the change of position.

The LEDs return to their normal state if the switch is returned to the original position selected prior to the last energization.

Phase control relay with voltage regeneration: RM17TT00

■

The relay monitors its own supply voltage Un.

•

The relay monitors:

— correct sequence of the three phases

— failure of at least one of the three phases (U measured < 0.7 x Un)

•

In the event of a sequencing or phase failure fault, the relay opens instantly.

•

When the fault is cleared, the output relay re-energizes instaneously.

3-phase supply and motor temperature control relays RM35TM

RM35TMpppMW



Motor temperature measurement and control relays RM35TM50MW and

RM35TM250MW monitor the following, on 3-phase supplies: correct sequencing of phases L1, L2 and L3, phase failure, and motor temperature via PTC probes (with or without memory).

The phase and temperature control functions are independent of each other.

These control relays accept different nominal 3-phase voltage values: 208–480 Vac.

They also detect line breaks or short-circuiting of the probes.

A version with fault memory and Test/Reset function is available.

Relays RM35TM50MW and RM35TM250MW monitor:

•

The status of the 3-phase supply

•

The temperature of motors with embedded PTC probes

The phase and temperature control functions are independent of each other

The 3-phase supply control function (208–480 V) monitors:

•


•

Total failure of a phase, including the case of regeneration (asymmetry greater than 30% of the average of the three phases)

Phase and temperature control relays: RM35TM50MW and

RM35TM250MW

■

3-phase supply control

As soon as phase sequence (L1, L2, L3) and phase presence (symmetry of their amplitude < 30%) are correct, the output relay contact closes and

LED R2 illuminates.

In the event of total failure or drop in amplitude of a phase (phase failure with regeneration) or inversion of phase sequence, the output relay contact opens and LED R2 goes out.

L3

L2

The result of the control is indicated by the status of output relay R2.

N.O. contact 21-24 opens in the event of a fault.

■

Temperature control

The temperature control relay can take up to 6 PTC (positive temperature coefficient) probes wired in series between terminals T1 and T2.

A fault is declared when the resistance of the temperature sensing circuit exceeds 3100

Ω.

Return to normal status is detected when the resistance is once again below 1650

Ω.

The result of the control is indicated by the status of the temperature output relay. N.O. contact 11-14 opens in the event of a fault.

Opening of the thermal sensing circuit, which has the same effect as a high temperature (resistance exceeds 3100

Ω) is therefore interpreted as a fault.

Total short-circuiting of the temperature probe(s), detected when resistance is less than 15

Ω ± 5 Ω, is treated as a fault.

LED R1 illuminates when the temperature is correct.

3-phase supply and motor temperature control relay RM35TM250MW Operating principle

Phase and temperature control relay

(with or without memory): RM35TM250MW

Configuration

The configuration is taken into account when relay RM35TM250MW is energized.

Selection of operating mode:

Set the switch to the required operating mode:

•

Temperature control without memory

•

Temperature control with memory

On energization, placing the switch in one of the five intermediate positions holds the relay in the open contact state and the error is signalled by simultaneous flashing of the LEDs.

The position of the mode selector switch is taken into account on energization. Any modification of its position during operation has no effect.

The active configuration may therefore be different from that indicated by the switch. In this case, the RM35TM250MW operates normally but the fact that the configuration has been changed is signalled by simultaneous flashing of the three LEDs.

■ Memory

Relay version RM35TM250MW has a selector switch which allows the temperature control operating mode to be configured with or without memory.

In memory mode, when a fault is detected, the temperature relay locks in the open position.

As soon as the temperature returns to the correct value, the relay can be unlocked (reset), either by pressing the Test/Reset button (for at least

50 ms), or by closing a volt-free contact (for at least 50 ms) between terminal Y1 and T1 (without a parallel load).

Relay RM35TM250MW can also be reset by switching the power off then on (see reset time).

■

Use of the Test/Reset button

Relay version RM35TM250MW has a Test/Reset button which can be used to check that the temperature control function is working correctly and to reset this function after locking in memory mode.

The press and release times are 50 ms for both functions.

When the temperature is normal, pressing the Test/Reset button simulates overheating. The temperature output relay contact opens and the no fault

LED goes off.

If memory mode is not active, the fault indication is maintained for as long as the button is pressed.

If memory mode is active, fault indication is locked and the button must be released then pressed again to reset the function.

In memory mode, when a fault is detected and the temperature returns to normal, the temperature control relay can be unlocked (reset) by pressing the Test/Reset button.

Single-phase and DC voltage control relays RM17UAS and RM17UBE


Voltage control relays RM17UAS and RM17UBE monitor:

•

The voltages of single-phase and d.c. supplies

These products monitor their own supply voltage.

RM17UASpp relays give the user a choice of two operating modes:

•

Overvoltage or undervoltage

•

Fault memory selected or not

An adjustable time delay, on crossing the thresholds, provides immunity to transients, thus preventing spurious triggering of the output relay.


U

U

Overvoltage or undervoltage control relays: RM17UAS14,

RM17UAS15 and RM17UAS16

The operating mode is fixed by the user:

A switch allows selection between the following modes:

•

Undervoltage with or without memory

•

Overvoltage with or without memory

The position of the switch, and therefore the operating mode, is read by the product on energization.

If the switch is set to an unacceptable position, the product detects a fault, the output relay stays open, and the LEDs flash to signal the position error.

If the switch position is changed while the device is operating, all the LEDs flash, but the product continues to operate normally with the function selected at the time of energization preceding the change of position.


The undervoltage or overvoltage threshold value is set by means of a graduated potentiometer clearly indicating the Un to be monitored.

The hysteresis is adjusted by means of a potentiometer graduated from

5–20% of the threshold setting. The hysteresis value must not exceed the limit values of the measuring range.

If the voltage controlled exceeds the threshold setting for a time greater than that set on the front panel (0.1–10 s), the output relay opens and

LED R goes out.

As soon as the voltage returns to a value above (or below) the threshold setting minus (or respectively plus) the hysteresis, the relay instantly closes.

Memory mode

If Memory mode is selected, the relay opens when crossing of the threshold is detected and then stays in that position.

The power must be switched off to reset the product.

Single-phase and DC voltage control relays RM17UBE Operating principle

Overvoltage and undervoltage control relays:

RM17UBE15 and RM17UBE16

Relays RM17UBE operate in window mode. They check that the voltage controlled stays between a minimum threshold and a maximum threshold.

The undervoltage or overvoltage threshold values are set by means of two graduated potentiometers clearly indicating the Un to be monitored.

The hysteresis is fixed at 3% of the threshold setting.

If the voltage controlled exceeds the high threshold setting, or falls below the low threshold setting for a time greater than that set on the front panel

(0.1–10 s), the output relay opens and LED R goes out. During the time delay, this LED flashes.

As soon as the voltage falls below the high threshold setting value minus the hysteresis, or rises above the low threshold setting value plus the hysteresis, the relay instantly closes.

Current control relays RM17JC Operating principle


•

Control relay RM17JC00MW is designed to monitor overcurrent.

•

It is equipped with an integrated current transformer.

•


Current control relay

Relay RM17JC00MW controls overcurrent.

The relay closes when the current exceeds the threshold setting on the front panel and opens when it drops below the threshold minus the hysteresis.

When terminal Y1 is linked to A1 (+), the output is reversed. The relay opens when the current exceeds the threshold setting on the front panel and closes again when it drops below the hystereris value.

Level control relays RM35L Product description


Level control relays RM35LM33MW and RM35LV14MW control one or two levels, with fill or empty function:

•

RM35LM33MW: control by resistive level probe

•

RM35LV14MW: control by discrete sensor




RM35LpppMW

Applications

These devices monitor the levels of conductive liquid or non-conductive material. They control the actuation of pumps or valves to regulate levels.

They are also suitable for protecting submersible pumps against dry running, or protecting tanks from overflow. They can also be used to control dosing of liquids in mixing processes, and to protect heating elements in the event of non immersion.

They have a transparent, hinged cover on their front panel to prevent accidental alteration of the settings. This cover can be directly sealed.

■

Application examples for RM35LM33MW:

• spring, town, industrial and sea water

• metallic salt, acid or base solutions

• liquid fertilizers

• non concentrated alcohol (< 40%)

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

■

Application examples for RM35LV14MW:

• chemically pure water

• fuels, liquid gasses (inflammable)

• oil, concentrated alcohol (> 40%)

• ethylene, glycol, paraffin, varnish and paints

Control relays RM35LM and RM35LV are designed to control levels of:

•

Conductive liquid for RM35LM

•

Any other material for RM35LV

Relay RM35LM measures the levels by means of resistive probes.

Relay RM35LM controls the levels of conductive liquids.

The operating principle is based on measurement of the apparent resistance of the liquid between two submerged probes. When this value is less than the threshold setting on the front panel of the device, the relay changes state. To avoid electrolytic phenomena, an a.c. current runs across the probes. A selector switch on the front panel allows selection of the required function and sensitivity range. Control of one single level can be achieved by using the 2 nd

selector switch.

In this case, the Max level probe stays up in the air and an adjustable time delay avoids any wave effect.

Relay RM35LV measures the levels by means of discrete sensors.

These two products activate their output relay when a tank is either emptying or filling.

A green LED indicates that the supply is ON.

A yellow LED indicates the state of the output relay.

A yellow LED indicates that timing is in progress.

The green and yellow LEDs flash to indicate an unacceptable setting position.

Level control relay: RM35LM33MW

Configuration

A selector switch on the front panel allows selection of the required sensitivity range and of the empty or fill function.

A second switch allows selection of the number of levels (1 or 2) and the type of time delay in the case of 1 level mode.

The configuration of these switches is taken into account on energization.

3-phase and single-phase pump control relays RM35BA


Measurement and control relay RM35BA10 is used for control and monitoring of 3-phase and single-phase pumps.

It monitors:

•

The sequence of phases L1, L2 and L3

•

The absence of one or more phases

•

Undercurrent for protection against running empty

•

Overcurrent for protection against overload

This control relay accepts different nominal voltage values:

•

208–480 Vac in 3-phase mode

•

230 Vac in single-phase mode

It is self-powered and measurements are true rms values.

Pump control relay RM35BA10 can operate on a single-phase or 3-phase supply.

It incorporates 3 functions in a single unit:

•

Current control

•

Phase presence control (in 3-phase mode)

•

Phase sequence control (in 3-phase mode)

It has two operating modes which are designed to control a pump via two external signal inputs (Y1 Y2).

These two signals are controlled by volt-free contacts.

Control inputs Y1 and Y2 can be connected to:

•

A level sensor

•

A level relay

•

A pressure sensor

•

A pushbutton

Fault signalling is by LED with differentiation of the cause of the fault.

Single-phase or 3-phase supply

If the control relay is configured for a single-phase supply, it monitors the current consumed by the pump.

If the control relay is configured for a 3-phase supply, it monitors the current, phase sequence and phase failure.

If a phase fault is detected, the output relay opens immediately.

On energization, if there is a phase sequence or phase failure fault, the output is unable to energize.

The overcurrent and undercurrent values are set by two separate potentiometers, graduated from 1 to 10 A.

In the event of a setting error (low threshold greater than high threshold) the output relay opens and all the LEDs flash to signal the error.

If a current fault occurs (overcurrent or undercurrent) the relay opens when the fault persists for longer than the threshold time delay setting.

When the current returns to a correct value, the output relay stays open. It can only be re-energized by a RESET: either by switching off the power, or by closing of external contact Y2 (in single control mode).

An inhibition time delay on energization (Ti) allows detection of current peaks on starting of the motor.

Frequency control relay RM35HZ monitors:

•

Frequency variations on 50 or 60 Hz supplies

•

It allows monitoring of over-frequency and under-frequency, via adjustment of two independent thresholds. It has two relay outputs: one per threshold.


■

Function selector switch:

•

Set the switch to 50 or 60 Hz according to the supply monitored, then select Memory or No memory mode. The position of the switch, and therefore the operating mode, is read by the product on energization.

•

If the switch is set to an unacceptable position, the product detects a fault, the output relays stay open and the LEDs flash to signal the position error.

•


LEDs flash, but the product continues to operate normally with the function selected at the time of energization preceding the change of position.

•


F

■

The relay monitors its own supply voltage Un:

The under-frequency or over-frequency threshold values are set by means of two graduated potentiometers indicating the variation value of the frequency to be monitored.

A switch x1 / x2 allows the control scale to be doubled. Hysteresis is fixed at 0.3 Hz.

If the frequency of the voltage controlled exceeds the over-frequency threshold setting for a time greater than that set on the front panel

(0.1–10 s), the corresponding output relay opens and its LED goes out.

During the time delay, this LED flashes.

As soon as the frequency drops below the value of the threshold setting, minus the hysteresis, the relay closes.

If the frequency of the voltage controlled falls below the under-frequency threshold setting for a time greater than that set on the front panel

(0.1–10 s), the corresponding output relay opens and its LED goes out.

During the time delay, this LED flashes.

As soon as the frequency rises above the value of the threshold setting, plus the hysteresis, the relay closes.


■ Memory mode:

If Memory mode is selected, the relay opens after the time delay and stays in that position when crossing of the threshold is detected.

Relay RM35S0MW monitors the speed (rate, frequency) of a process

(conveyor, conveyor belt, etc.) via discrete sensors:

•

3-wire PNP or NPN proximity sensor

•

0-30 V voltage input

•

NAMUR proximity sensor

•

Volt-free contact

It can be used for monitoring underspeed or overspeed.

Speed control relay: RM35S0MW

■

Measurement

The cycle of the process being monitored is the series of impulses characterized by a two-state signal: high and low. The speed measurement is obtained by measuring the period of this signal, from the first change of state detected (either rising or falling edge). Digital processing of the signal allows the disparity between the signals to be calculated. At power up, or after appearance (or reappearance) of the sensor signal, detection of the signal requires processing of one or more periods (maximum of two).

During this time, control is inoperative.

■

Operating mode

Using the switch, select one of the four operating modes:

•

Underspeed without memory

•

Underspeed with memory

•

Overspeed without memory

•

Overspeed with memory

When relay RM35S is configured to memory mode, if underspeed is detected, the output relay stays in the off (alarm) state whatever the further evolution of the process speed. It cannot return to the on (normal) state until contact S2 closes (for at least 50 ms). When S2 re-opens, if the speed is not high enough, the relay returns to the locked, off (alarm) state. Relay

RM35S can also be reset by a power break of at least 1 s; the relay then returns to the on (normal) state for at least the duration of the time delay, whatever the process speed.

At power up, in order to allow the process being monitored to reach its nominal operating speed, relay RM35S is inhibited for a time delay adjustable from 0.6–60 s. This time delay can be adjusted (shortened or lengthened) during inhibition. Relay RM35S can also be inhibited by closing of contact S2: on starting, for example, if the process run up to speed time is greater than 60 s, or at any time during operation. Whether it results from a starting inhibition time delay or closing of S2, inhibition keeps the output relay in the closed position and is signalled by illumination of the inhibition LED. If, after lifting of inhibition (end of starting inhibition time delay or opening of contact S2), the signal detection phase has not been completed, the relay drops out after the set wait time between two impulses (measured as from the end of inhibition). Inhibition must last as long as is necessary for the product to detect at least 2 periods. When the signal has not been characterized by the end of the inhibition period, the inhibition LED flashes for as long as speed measurement is impossible. It is also possible to inhibit relay RM35S at any time, during operation, by closing S2.

Overspeed control

At the end of the starting inhibition time delay, Ti, as soon as the speed measured is higher than the threshold setting, the output relay changes state from closed to open.

It returns to its initial state when the speed is again lower than the threshold minus hysteresis (fixed at 5% of the threshold setting).

When power is restored to relay RM35S, after a break of at least 1 s, the relay is in the on (normal) state during the time delay and stays in that state for as long as the speed remains lower than the threshold.

When relay RM35S is configured to memory mode, if overspeed is detected, the output relay stays in the off (alarm) state whatever the further evolution of the process speed.

It cannot return to the on (normal) state until contact S2 closes (for at least

50 ms).

When S2 re-opens, if the speed is too high, the relay returns to the locked off (alarm) state.

Relay RM35S can also be reset by a power break of at least 1 s; the relay then returns to the on (normal) state for at least the duration of the time delay, whatever the process speed.

At power up, in order to allow the process being monitored to reach its nominal operating speed, relay RM35S is inhibited for a time delay adjustable from 0.6–60 s. This time delay can be modified (shortened or lengthened) during inhibition.

Relay RM35S can also be inhibited by closing of contact S2: on starting, for example, if the process run up to speed time is greater than 60 s, or at any time during operation.

Whether it results from a starting inhibition time delay or closing of S2, inhibition keeps the output relay in the closed position and is signalled by illumination of the inhibition LED.

If, after lifting of inhibition (end of starting inhibition time delay or opening of contact S2), the signal detection phase has not been completed, the relay drops out after the set wait time between two impulses (measured as from the end of inhibition).

Inhibition must last as long as is necessary for the product to detect at least

2 periods.

When the signal has not been characterized by the end of the inhibition period, the inhibition LED flashes for as long as speed measurement is impossible.

It is also possible to inhibit relay RM35S at any time, during operation, by closing S2.

Control Measurement Relays Operating principle



Temperature control relays for elevator machine rooms are designed to monitor the temperature between 41 °F (5 °C) and 104 °F (40 °C) in compliance with directive EN81.

Tt: Time delay after crossing of the temperature threshold (adjustable on front panel)

Temperature control relay: RM35ATL0MW

After a delay on pick-up after energization, and for as long as the temperature monitored by the PT100 probe remains between the two thresholds set on the front panel, the output relay is closed and the yellow

LEDs are on.

When the temperature crosses one of the threshold settings on the front panel (high or low threshold), the time delay set on the front panel (Tt) is activated. The yellow LED corresponding to the threshold crossed (low or high), flashes.

At the end of the time delay, if the temperature is still outside the threshold setting, the output relay opens and the yellow LED corresponding to the threshold crossed goes out.

The output relay closes instantly (within the response time on disappearance of a fault) when the temperature returns within the window of the two threshold settings on the front panel, plus the fixed hysteresis.

If the PT 100 probe is incorrectly wired (missing or short-circuited) the relay is open and the 3 LEDs flash.

Temperature and phase control relay: RM35ATW5MW

After a delay on pick-up after energization, and for as long as the temperature monitored by the PT100 probe remains between the two threshold settings on the front panel, the temperature relay R1 is closed.

When the temperature crosses one of the threshold settings on the front panel (high or low threshold), the time delay set on the front panel (Tt) is activated. The yellow temperature LED flashes. At the end of the time delay, if the temperature is still outside the threshold setting, the output relay R1 opens and the yellow LED goes out.

The output relay R1 closes instantly when the temperature returns to within the window of the two threshold settings on the front panel, plus or minus the fixed hysteresis.

The device also monitors the correct sequence of phases L1, L2 and L3 of the 3-phase supply and total phase failure, even in the case of phase regeneration (< 70%).

After a delay on pick-up after energization, and for as long as phase presence and phase sequence are correct, relay R2 and the "phase" LED are On. When a fault appears, the "phase" relay opens and the "phase"

LED instantly goes out (response time on appearance of a fault).

When the fault disappears, the phase control relay and LED are activated

(response time on disappearance of a fault).

If the PT 100 probe is incorrectly wired (missing or short-circuited) relay R1 is open and LED R1 flashes.
