Zelio Control - modular measurement and control relays 3

3-phase supply control relaysRM17 TG

PresentationRM17 TG�0 measurement and control relays for 3-phase supplies monitor 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 V for RM17 TG00,� � 208…440 V for RM17 TG20.

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

Control status is indicated by a LED.

The relays are designed for clip-on mounting on � rail

Applications� Control for connection of moving equipment (site equipment, agricultural equipment, refrigerated trucks).� Control for protection of persons 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).� Normal/emergency power supply switching.

Operation 3 Zelio Control - modular measurement and control relays 3

3-phase supply control relays RM17 TG

Operating principle3-phase supply control relays monitor: � Correct sequencing of phases L1, L2 and L3.

Fault signalling is by LED.

Phase control relays: RM17 TG��0The 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 V), 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 V) the relay opens instantly and the LED goes out.

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

3-phase supply and motor temperature control relays RM35 TM

Presentation Motor temperature measurement and control relays RM35 TM50MW and RM35 TM250MW 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 V.They also detect line breaks or short-circuiting of the probes.A version with fault memory and Test/Reset function is available.Settings are protected by a sealable cover.Control status is indicated by a LED.The relays are designed for clip-on mounting on � rail

Operating principleRelays RM35 TM50MW and RM35 TM250MW 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:� The correct sequence of phases L1, L2, L3: � Total failure of a phase, including in the case of regeneration (asymmetry greater than 30 % of the average of the three phases).

Phase and temperature control relays: RM35 TM50MW and RM35 TM250MW� 3-phase supply controlAs soon as phase sequence (L1, L2, L3) and phase presence (symmetry of their amplitude < 30 %) are considered to be correct, the output relay contact closes and LED R2 is lit.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.

The result of the control is indicated by the status of output relay R2, N/O contact 21-24 open in the event of a fault.

�� Temperature controlThe 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 open 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 is lit when the temperature is correct.

Phase and temperature control relay (with or without memory): RM35 TM250MWConfiguration

The configuration is taken into account when relay RM35 TM250MW is energised.Selection of operating mode: Set the switch to the required operating mode: � Temperature control without memory,� Temperature control with memory.

On energisation, 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 energisation. Any modification of its position during operation has no effect: the active configuration may therefore be different from that indicated by the switch; the RM35 TM250MW operates normally but the fact that the configuration has been changed is signalled by simultaneous flashing of the three LEDs.

� Memory Relay version RM35 TM250MW 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 RM35 TM250MW can also be reset by switching the power off then on (see reset time).

� Use of the “Test/Reset” buttonRelay version RM35 TM250MW 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 is open and the "no fault" LED is 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 has been detected and the temperature has returned to normal, the "temperature" control relay can be unlocked (reset) by pressing the "Test/Reset" button.

Operating principleVoltage control relays RM17 UAS and RM17 UBE monitor: � The voltages of single-phase and d.c. supplies.

These products monitor their own supply voltage.

RM17 UAS�� 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, so preventing spurious triggering of the output relay.


Overvoltage or undervoltage control relays: RM17 UAS14, UAS15 and UAS16The 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 energisation.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 energisation preceding the change of position.The LED's return to their normal state if the switch is returned to the original position selected prior to the last energisation.

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" modeIf "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.

Overvoltage and undervoltage control relays: RM17 UBE15 and UBE16Relays RM17 UBE 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.

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

Operating principleControl relays RM35 UA1�MW are designed for the monitoring of a.c. or d.c. voltages.

They automatically recognise the form of the � or � (50 or 60 Hz) signal.


Overvoltage and undervoltage control relays: RM35 UA11MW, UA12MW and UA13MW � 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 energisation.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 energisation preceding the change of position.The LED's return to their normal state if the switch is returned to the original position selected prior to the last energisation.

The undervoltage or overvoltage threshold value is set by means of a potentiometer graduated as a percentage of the scale value of Un to be monitored.The hysteresis is adjusted by means of a potentiometer graduated from 5…50 % of the threshold setting. The hysteresis value must not exceed the limit values of the measuring range.In overvoltage mode, if the voltage controlled exceeds the threshold setting for a time greater than that set on the front panel (0.3…30 s), the output relay opens and LED R goes out. During the time delay, this LED flashes.As soon as the voltage drops below the value of the threshold setting, minus the hysteresis, the relay instantly closes. In undervoltage mode, if the voltage controlled falls below the threshold setting for a time greater than that set on the front panel (0.3…30 s), the output relay opens and LED R goes out. During the time delay, this LED flashes.As soon as the voltage rises above the value of the threshold setting, 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.

Operating principleControl relays RM35 JA3�MW are designed for the monitor of a.c. or d.c. currents.

They automatically recognise the form of the � or � (50 or 60 Hz) signal and can provide direct monitor up to 15 A. Above this value, a current transformer can be connected.


a.c. or d.c. current control relays: RM35 JA31MW and JA32MWThe operating mode is fixed by the user: A switch allows selection between the following modes: � Undercurrent, with or without memory,� Overcurrent, with or without memory.The position of the switch, and therefore the operating mode, is read by the product on energisation.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 energisation preceding the change of position.The LED's return to their normal state if the switch is returned to the original position selected prior to the last energisation.

The undercurrent or overcurrent threshold value is set by means of a potentiometer graduated as a percentage of the scale value of I to be monitored.The hysteresis is adjusted by means of a potentiometer graduated from 5…50 % of the threshold setting. The hysteresis value must not exceed the limit values of the measuring range.In overcurrent (undercurrent) mode, if the current exceeds (falls below) the threshold setting for a time greater than that set on the front panel (0.3…30 s), the relays open and the LED goes out.As soon as the current returns to below (above) the threshold minus (plus) hysteresis, the relay instantly closes again.

"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.

On energisation, an inhibit time delay (1…20 s) makes it possible to inhibit current peaks (or troughs) on start-up of equipment.

Level control relays RM35 L

Presentation Level control relays RM35 LM33MW and RM35 LV14MW control one or two levels, with fill or empty function:� RM35 LM33MW: control by resistive level probe,� RM35 LV14MW: control by discrete sensor.

Settings are protected by a sealable cover.Control status is indicated by a LED.The relays are designed for clip-on mounting on � rail

ApplicationsThese 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 avoid any accidental alteration of the settings. This cover can be directly sealed.

� Application examples for RM35 LM33MW:� 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 RM35 LV14MW:� chemically pure water,� fuels, liquid gasses (inflammable),� oil, concentrated alcohol (> 40 %),� ethylene, glycol, paraffin, varnish and paints.

Operating principleControl relays RM35 LM and RM35 LV are designed to control levels of: � Conductive liquid for RM35 LM,� Any other material for RM35 LV.

Relay RM35 LM measures the levels by means of resistive probes.Relay RM35 LM 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 2nd selector switch.In this case, the Max level probe stays up in the air and an adjustable time delay avoids any wave effect.

Relay RM35 LV 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: RM35 LM33MWConfiguration

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 energisation.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 energisation preceding the change of position.The LED's return to their normal state if the switch is returned to the original position selected prior to the last energisation.

Function diagram �� Control of two levels� Fill/Empty function

� empty functionlevel: 2, function:

- LS (Low Sensitivity: 250 Ω…5 kΩ), - St (Standard Sensitivity: 5 kΩ…100 kΩ), - HS (High Sensitivity: 50 kΩ…1 MΩ).

The output relay stays open until the liquid reaches the Max. level probe. As soon as the Max. level is reached, the contact closes and then allows emptying of the tank (valve opens, pump starts, ...). When the level drops below the Min. level, the contact opens to stop the emptying process.

Note: When two levels are controlled, the anti-wave time delay function is not active.

� fill functionlevel: 2, function:


The output relay stays energised until the liquid reaches the Max. level probe. As soon as the Max. level is reached, the contact opens and the pump stops. When the level drops below the Min. level, the contact closes again and pumping re-starts to raise the level.

3-phase and single-phase pump control relays RM35 BA

PresentationMeasurement and control relay RM35 BA10 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 V in 3-phase mode,� � 230 V in single-phase mode.

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

Settings are protected by a sealable cover.Control status is indicated by a LED.

Operating principlePump control relay RM35 BA10 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, etc...

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

3-phase and single-phase pump control relayThe operating mode is fixed by the user: A switch allows selection between the following modes:� Single control,� Double control,� Single-phase or 3-phase supply.The position of the switch, and therefore the operating mode, is read by the product on energisation.

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 energisation preceding the change of position.The LED's return to their normal state if the switch is returned to the original position selected prior to the last energisation.

Function diagrams Single control mode � Functions : � Single control mode (3ph/1ph).

This mode is designed to control a pump via an external signal.The relay output is closed when the signal is present at Y1 (contact closed).Y2 can be used to reset the relay after a current fault.

� Double control mode (3ph/1ph). Double control mode

This mode is designed to control a pump via two external control signals (Y1 and Y2).The output relay closes when both input signals are present (Y1 and Y2 closed).It will open as soon as one of these signals disappears.

Ti: time delay to inhibit fault monitoring on starting of pump (overcurrent and undercurrent, setting on front panel).Tt: time delay in the event of a fault (overcurrent or undercurrent, setting on front panel).I. Def.: presence of a current fault (overcurrent or undercurrent)

3-phase and single-phase pump control relay (continued)Function diagrams � Control

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 energisation, if there is a phase sequence or phase failure fault, the output is unable to energise.

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 is open 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-energised 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 energisation (Ti) allows detection of current peaks on starting of the motor.

� Functions : � Overcurrent detection. > I

� Undercurrent detection. < I.

Ti : time delay to inhibit fault monitoring on starting of pump (overcurrent and undercurrent, setting on front panel).Tt: time delay in the event of a fault (overcurrent or undercurrent, setting on front panel).

Operating principleFrequency control relay RM35 HZ 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 frequency of 50 or 60 Hz of 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 energisation.� 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.� 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 energisation preceding the change of position.� The LED's return to their normal state if the switch is returned to the original position selected prior to the last energisation.

� 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 instantly 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 instantly closes. On energisation of the device with a fault measured, the relay stays open.

� "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.The power must be switched off to reset the product.

Operating principleRelay RM35 S0MW monitors the speed (rate, frequency) of a process (conveyor, conveyor belt, etc.) via discrete sensors: 3-wire PNP or NPN proximity sensor, or 0-30 V voltage input, or NAMUR proximity sensor, or volt-free contact.It can be used for monitoring underspeed or overspeed.

Speed control relay: RM35 S0MW�� MeasurementThe cycle of the process being monitored is the series of impulses characterised 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 (characterisation) of the signal requires processing of one or more periods (maximum of two). During this time, control is inoperative.� Operating modeUsing the switch, select one of the four operating modes: � Underspeed without memory,� Underspeed with memory,� Overspeed without memory,� Overspeed with memory.

Function diagrams �� Underspeed control� Function: Underspeed control - Underspeed� Without memory - No Memory

At the end of the starting inhibition time delay "Ti", as soon as the speed measured drops below the threshold setting, the output relay changes state from "closed" to "open".It returns to its initial state when the speed is again higher than the threshold plus hysteresis (fixed at 5% of the threshold setting).When power is restored, after a break having lasted 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 higher than the threshold.

� With memory Memory When relay RM35 S has been configured in "memory" mode, if underspeed is detected, the output relay stays in the off ("alarm") state whatever the further evolution of the process speed. It will not be able to return to the on ("normal") state until contact S2 closes (for at least 50 ms). If, when S2 re-opens, the speed is not high enough, the relay returns to the locked, off ("alarm") state.Relay RM35 S can also be reset by a power break (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.

� With inhibition by S2 - Inhib./S2 At power up, in order to allow the process being monitored to reach its nominal operating speed, relay RM35 S is inhibited for a time delay adjustable from 0.6…60 s. This time delay can be adjusted (shortened or lengthened) during inhibition.Relay RM35 S 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 'characterised' 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 RM35 S at any time, during operation, by closing S2.

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 RM35 S, after a break having lasted 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.

Operating principleTemperature control relays for elevator machine rooms are designed to monitor the said temperature between 5°C and 40°C in compliance with directive EN81.

Temperature control relay: RM35 ATL0MWAfter a delay on pick-up after energisation, 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 control relay: RM35 ATR5MWAfter a delay on pick-up after energisation, and for as long as the temperature monitored by the PT100 probe remains between the two threshold settings on the front panel, the output relays are closed and their 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 one of the threshold settings, the corresponding output relay opens and the yellow LED corresponding to the threshold crossed goes out.The output relay closes instantly (response time on disappearance of a fault) when the temperature returns within the window of the two threshold settings on the front panel, plus (or minus) the fixed hysteresis.

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

Temperature and phase control relay: RM35 ATW5MWAfter a delay on pick-up after energisation, 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 energisation, 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.

The supply voltage to be monitored is connected to terminals L1, L2, L3 of the product.

There is no need to provide a separate power supply for RM4 T relays, they are self-powered by terminals L1, L2, L3.

�� Monitoring rotational direction of phases and detection of complete failure of one or more phases (RM4 T all models):��When terminals L1, L2, L3 are energised, the relay is energised and the yellow LED comes on if the rotational direction of phases is correct and if all 3 phases are present.��If one or more of the phases have failed or if the rotational direction is incorrect, the relay is not energised at switch-on.��In normal operation (no fault) the relay is energised; it de-energises instantaneously in the event of failure of one or more of the phases (any time delay set is not active on these faults).��In the event of failure or absence of a single phase, a voltage greater than the detection threshold (≈ 130 V on RM4 TG, undervoltage threshold setting on RM4 TU and RM4 TR) can be generated back through the control circuit, thus preventing detection of the phase failure. In this case, we recommend the use of RM4 TA relays.��The absence of a phase is signalled, on RM4 TR and RM4 TA, by illumination of LED “P”.

�� Overvoltage and undervoltage detection (RM4 TR):��In normal operation, the relay is energised and LEDs "U" and "R" are illuminated.��If the average of the 3 voltages between phases goes outside the range to be monitored, the output relay is de-energised:

- overvoltage: the red LED “> U” illuminates,- undervoltage: the red LED “< U” illuminates.

��When the supply returns towards its rated value, the relay is re-energised according to the hysteresis value (5 %) and the corresponding red LED goes out.��A selector switch allows selection of an adjustable time delay from 0.1 s to 10 s. With function transient "over" or "under" voltages are not taken into account. With function all variations above or below are taken into account and re-energisation of the relay is delayed.��In all cases, in order to be detected, the duration of the overvoltage or undervoltage must be greater than the measuring cycle time (80 ms).

�� Undervoltage detection only (RM4 TU)��In normal operation, the output relay is energised and the yellow LED is illuminated.��If the average of the 3 voltages between phases is less than the undervoltage threshold setting, the relay is de-energised after 550 ms and the red LED “< U” illuminates.

t : fixed time delay = 550 ms

�� Detection of phase asymmetry (RM4 TA)��In normal operation, the output relay is energised and the yellow and green LEDs are illuminated. ��In the event of an asymmetry fault, after a time delay set between 0.1 s and 10 s (on RM4 TA3 only), the output relay is de-energised, the yellow LED goes out and red LED “A” illuminates (RM4 TA3� only).��The relay re-energises when the asymmetry value measured is less than half of the asymmetry value setting (hysteresis).

t : time delay

Example: asymmetry set at 10 %, mains supply voltage 400 V

- relay de-energisation threshold: 400 V – 10 % = 360 V, 10 %,- relay re-energisation threshold: 400 V – 10% = 380 V.

Note : If there is distortion of the 3-phase supply sine wave, malfunctioning of the RM4 T 3-phase supply control relay is possible.

The supply voltage is connected to terminals A1-A2. The voltage to be monitored is connected to terminals B1, B2 or B3 and C.

Hysteresis is adjustable between 5 and 30%: for overvoltage h = (US1 - US2) / US1, for undervoltage h = (US2 - US1) / US1. A measuring cycle lasts only 80 ms, which allows rapid detection of changes in voltage.

Relay set for overvoltage detection (RM4 UA0� or selector on “>” for model RM4 UA3�) :If the voltage is > the setting threshold US1, the output relay is energised with or without a time delay. When the voltage returns to a value US2 below the threshold, depending on the hysteresis setting, the relay is instantaneously de-energised.

Relay set for undervoltage detection (selector on “<”, model RM4 UA3� only):If the voltage is < the setting threshold US1, the output relay is energised with or without a time delay. When the voltage returns to a value US2 above the threshold, depending on the hysteresis setting, the relay is de-energised.

�� Functions� Overvoltage control

Note: the measurement ranges can be extended above 500 V by adding a resistor, see page 3/103.The measurement range on � supply can be extended by means of a voltage transformer, the secondary of which is connected to the measuring terminals of the corresponding RM4.

The operating principle is based on a change in the resistance measured between immersed or non-immersed electrodes. Low resistance between electrodes: liquid present. High resistance between electrodes: no liquid present. The electrodes may be replaced by other sensors or probes which transmit values representing variations in resistance.The a.c. measuring voltage which is < 30 V and galvanically insulated from the supply and contact circuits, ensures safe use and the absence of any electrolysis phenomena.RM4 relays may be used:� For detection of a liquid level, operating with 2 electrodes, one reference electrode and one high level electrode, or an LA9 RM201 probe. Example: prevention of tank overflow.� For regulating a liquid level between a minimum and a maximum level, operating with 3 electrodes, one reference electrode, one low level electrode and one high level electrode, or two LA9 RM201 probes. Example: water tower.The state of the output relay can be configured:� Empty function : the output relay is energised when high level electrode B2 is immersed and is de-energised when low level electrode B3 is "dry" (1).� Fill function : the output relay is energised when the low level electrode is "dry" and is de-energised when high level electrode is immersed (1).On model RM4 LA32 a time delay can be set on energisation or de-energisation of the output relay in order to raise the maximum level function or to lower the minimum level function .This function also makes it possible to avoid pulsing of the output relay (wave effect) when operating with 2 electrodes .

Liquide level control relays RM4 L

� Select the empty /fill function according to the sequence to be performed.� If necessary, set potentiometer 1 to minimum (time delay).� Set potentiometer 2 to minimum; on RM4-LA, select the lowest sensitivity range using potentiometer 4 (5 or 5 ).� With all the electrodes immersed, turn the sensitivity potentiometer towards maximum until the relay is energised ( function) or de-energised ( function), then exceed the threshold by about 10 % to compensate for variation in the supply voltage.If the relay is not able to energise, a higher sensitivity scale must be used (selector 4 on RM4 LA32) or relay RM4 LG must be replaced by an RM4 LA32 relay and the adjustment procedure must be started again.� Then check that the relay de-energises ( function) or energises ( function) as soon as electrodes B3 and B2 are out of the liquid. If the relay does not de-energise, select a lower sensitivity scale.

This probe is of the "suspension" type. It is coaxial, i.e. in addition to the normal (central) electrode, the stainless steel skirt can also act as earth (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.

Setting-up

� 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.Note: the high level can be raised by means of the adjustable time delay from 0.1 to 10 seconds with function .The low level can be lowered by means of this same time delay with function .

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: 100 °C.Probe LA9 RM201 can also be fixed on various containers (cisterns, tanks, ...) by means of a bracket or other suitable fixing device.

Plug-in liquid level control relays RM 84 870

The output relay changes state when the level of the liquid reaches the maximum level probe, with the minimum level probe submerged. It returns to its initial state when the minimum level probe is no longer in contact with the liquid.

� Controlling the levels of conductive liquids� Regulation of two thresholds:� minimum,� maximum.� Emptying function.� Plug-in, 8 or 11-pin.� Sensitivity adjustable from 5 kΩ to 100 kΩ.

Operating principleControl of maximum and/or minimum levels of conductive liquids (tap water, sea water, waste water, chemical solutions, coffee ...).

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 output relay changes state. To avoid electrolytic phenomena, an a.c. current runs across the probes.

Applications in the food-processing, chemical industries, etc.
