3-phase supply control relays

RM17 TG

Presentation

RM17 TG

30 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:
1 4 208…480 V for RM17 TG00,

1 4 208…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

5 rail

Applications

1 Control for connection of moving equipment (site equipment, agricultural
equipment, refrigerated trucks).
1 Control for protection of persons and equipment against the consequences of
reverse running (lifting, handling, elevators, escalators, etc.).
1 Control of sensitive 3-phase supplies.

1 Protection against the risk of a driving load (phase failure).

1 Normal/emergency power supply switching.

3-phase supply control relays

RM17 TG

Operating principle

3-phase supply control relays monitor:
1 Correct sequencing of phases L1, L2 and L3.

Fault signalling is by LED.

Phase control relays: RM17 TG

11110

The relay monitors its own power supply.

The relay monitors:
1 Correct sequencing of the three phases,

1 Total loss of one or more of the phases.

When phase sequence and voltages are correct (>

4 183 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.

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

4 208… 480 V.

They monitor their own supply voltage, measured as a true rms value.
Settings are protected by a sealable cover.
Control status is indicated by a LED.
The relays are designed for clip-on mounting on

5 rail

Applications
1 Control for connection of moving equipment (site equipment, agricultural
equipment, refrigerated trucks).
1 Control for protection of persons and equipment against the consequences of
reverse running (lifting, handling, elevators, escalators, etc.).
1 Control of sensitive 3-phase supplies.

1 Protection against the risk of a driving load (phase failure).

1 Normal/emergency power supply switching.

Operating principle

3-phase supply control relays monitor:
1 The correct sequence of phases L1, L2, L3.

1 Phase failure, including in the case of voltage regeneration

1 Undervoltage from - 2…- 20 % of the supply voltage Un,

1 Overvoltage from 2…20 % of the supply voltage Un,

1 Asymmetry from 5…15 % of the supply voltage Un.

Fault signalling is by LED.

2222 Voltage selector switch :

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

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

2 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
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.

Phase control relay with voltage regeneration: RM17 TT00
2222 The relay monitors its own supply voltage Un:

2 The relay monitors:

- correct sequence of the three phases,
- failure of at least one of the three phases (U measured < 0.7 x Un).

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

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

supplies: the correct sequencing of phases L1, L2 and L3, failure of one or more of
these phases, asymmetry, as well as overvoltage and undervoltage with
independent settings.

Multi-voltage product.

This control relay accepts different nominal 3-phase voltage values:

4 220… 480 V.

It monitors its own supply voltage, measured as a true rms value.

Settings are protected by a sealable cover.

Control status is indicated by a LED.

The relay is designed for clip-on mounting on

5 rail.

Applications
1 Control for connection of moving equipment (site equipment, agricultural
equipment, refrigerated trucks).
1 Control for protection of persons and equipment against the consequences of
reverse running (lifting, handling, elevators, escalators, etc.).
1 Control of sensitive 3-phase supplies.

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:

46208… 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

5 rail

Applications
1 Control for connection of moving equipment (site equipment, agricultural
equipment, refrigerated trucks).
1 Control for protection of persons and equipment against the consequences of
reverse running (lifting, handling, elevators, escalators, etc.).
1 Control of sensitive 3-phase supplies.

1 Protection against the risk of a driving load (phase failure).

1 Normal/emergency power supply switching.

3-phase supply and motor temperature
control relays RM35 TM

Operating principle

Relays RM35 TM50MW and RM35 TM250MW monitor:
1 The status of the 3-phase supply,

1 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:
1 The correct sequence of phases L1, L2, L3:

1 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
1 3-phase supply control
As 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.

2222 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 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.

3-phase supply and motor temperature
control relays RM35 TM

Phase and temperature control relay (with or without memory):
RM35 TM250MW

Configuration

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

2 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.

1 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).

1 Use of the “Test/Reset” button
Relay 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.

1 Failure of one or more phases,

Measurements are made between Phases/Phases for the RM35 UB330 and the
RM17 UB310 and between Phases/Neutral for the RM35 UB3N30.
Fault signalling is by LED. RM35 UB relays allow differentiation on the source of the
fault (one LED for high threshold, one LED for low threshold).

2222 Voltage selector switch:

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

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

2 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
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.

Overvoltage/undervoltage control relays: RM35 UB330

The relay monitors its own supply voltage Un:
2 The relay monitors:

- failure of at least one of the three phases (U measured < 0.7 x Un),
- the undervoltage,
- the overvoltage.

2 Each threshold has its own independently adjustable time delay from 0.3 to 30 s.

2 In the event of a voltage fault, the corresponding relay (one undervoltage output /
one overvoltage output) opens at the end of the time delay set by the user.
2 In the event of phase failure, both relays open instantly without waiting for the end
of the time delay set by the user.
2 On energisation of the device with a fault measured, the relays stay open.

2 The relay monitors:

- the presence of neutral,
- the undervoltage,
- the overvoltage,
- phase failure.

2 Each threshold has its own independently adjustable time delay from 0.3 to 30 s.

2 In the event of a voltage fault, the corresponding relay (one undervoltage output /
one overvoltage output) opens at the end of the time delay set by the user.
2 In the event of absence of neutral or phase, both relays open instantly without
waiting for the end of the time delay set by the user.
2 On energisation of the device with a fault measured, the relays stay open.

Single-phase and d.c. voltage control relays
RM17 UAS and RM17 UBE

Operating principle

Voltage control relays RM17 UAS and RM17 UBE monitor:
1 The voltages of single-phase and d.c. supplies.

These products monitor their own supply voltage.

RM17 UAS

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

1 Overvoltage or undervoltage,

1 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.

Fault signalling is by LED.

Overvoltage or undervoltage control relays: RM17 UAS14, UAS15 and UAS16

The operating mode is fixed by the user:
A switch allows selection between the following modes:
1 Undervoltage with or without memory

1 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" 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 d.c. voltage control relays
RM17 UAS and RM17 UBE

Overvoltage and undervoltage control relays: RM17 UBE15 and UBE16

Relays 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.

Multifunction voltage control relays
RM35 UA

Operating principle

Control relays RM35 UA1

3MW are designed for the monitoring of a.c. or d.c.

voltages.

They automatically recognise the form of the

7 or 4 (50 or 60 Hz) signal.

Fault signalling is by LED.

Overvoltage and undervoltage control relays: RM35 UA11MW, UA12MW and
UA13MW
1 The operating mode is fixed by the user :
A switch allows selection between the following modes:
2 Undervoltage with or without memory,

2 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.

1 "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 principle

Control relays RM35 JA3

3MW are designed for the monitor of a.c. or d.c. currents.

They automatically recognise the form of the

7 or 4 (50 or 60 Hz) signal and can

provide direct monitor up to 15 A. Above this value, a current transformer can be
connected.

Fault signalling is by LED.

a.c. or d.c. current control relays: RM35 JA31MW and JA32MW

The operating mode is fixed by the user:
A switch allows selection between the following modes:
1 Undercurrent, with or without memory,

1 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:
1 RM35 LM33MW: control by resistive level probe,

1 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

5 rail

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

1 Application examples for RM35 LM33MW:

2 spring, town, industrial and sea water,

2 metallic salt, acid or base solutions,

2 liquid fertilizers,

2 non concentrated alcohol (< 40 %),

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

1 Application examples for RM35 LV14MW:

2 chemically pure water,

2 fuels, liquid gasses (inflammable),

2 oil, concentrated alcohol (> 40 %),

2 ethylene, glycol, paraffin, varnish and paints.

Level control relays RM35 L

Operating principle

Control relays RM35 LM and RM35 LV are designed to control levels of:
1 Conductive liquid for RM35 LM,

1 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 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 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 LM33MW

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 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.

LS (Low Sensitivity: 250

Ω…5 kΩ),

-

St (Standard Sensitivity: 5 k

-

HS (High Sensitivity: 50 k

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.

The output relay stays energised until the liquid reaches the Max. level probe. As

level drops below the Min. level, the contact closes again and pumping re-starts to
raise the level.

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

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

Presentation

Measurement and control relay RM35 BA10 is used for control and monitoring of
3-phase and single-phase pumps.
It monitors:
1 The sequence of phases L1, L2 and L3.

1 The absence of one or more phases,

1 Undercurrent for protection against running empty,

1 Overcurrent for protection against overload.

This control relay accepts different nominal voltage values:
1 4 208… 480 V in 3-phase mode,

1 4 230 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.

The relay is designed for clip-on mounting on

5 rail

Applications
1 Management of pumps.

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

Operating principle

Pump control relay RM35 BA10 can operate on a single-phase or 3-phase supply.
It incorporates 3 functions in a single unit:
1 Current control,

1 Phase presence control (in 3-phase mode),

1 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:
1 A level sensor,

1 A level relay,

1 A pressure sensor,

1 A pushbutton, etc...

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

3-phase and single-phase pump control relay

The operating mode is fixed by the user:
A switch allows selection between the following modes:
1 Single control,

1 Double control,

1 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

1 Functions :

2 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.

2 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).

3-phase and single-phase pump control relay (continued)

Function diagrams

1 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.

Frequency control relay

RM35 HZ

Operating principle

Frequency control relay RM35 HZ monitors:
2 Frequency variations on 50 or 60 Hz supplies.

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

Fault signalling is by LED.

2222 Function selector switch:

2 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.
2 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.
2 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.
2 The LED's return to their normal state if the switch is returned to the original
position selected prior to the last energisation.

1 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.

1 "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.

Speed control relays RM35 S

Operating principle

Relay 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
2222 Measurement
The 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.
1 Operating mode
Using the switch, select one of the four operating modes:
2 Underspeed without memory,

2 Underspeed with memory,

2 Overspeed without memory,

2 Overspeed with memory.

Function diagrams

2222 Underspeed control

1 Function: Underspeed control - Underspeed

2 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.

2 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.

2 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.

2 Without memory- No Memory

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 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.

2 With memory - Memory

When relay RM35 S has been configured in "memory" mode, if overspeed 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 too high, 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.

2 With inhibition by S2. - Inhib./S2

At power up, in order to allow the process being monitored to reach its nominal

0.6…60 s. This time delay can be modified (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

Temperature control relays RM35 AT

1 for

elevator machine rooms and 3-phase supplies

Operating principle

Temperature 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 ATL0MW

After 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 ATR5MW

After 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 ATW5MW

After 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.

Electrical durability of contacts on resistive load

Example:

L/R with load protection diode

An LC1-F185 contactor supplied with 115 V/50 Hz for a consumption of 55 VA or a current consumption
equal to 0.5 A and cos

ϕ = 0.3.

For 0.5 A, curve 1 indicates a durability of approximately 1.5 million operating cycles.
As the load is inductive, it is necessary to apply a reduction coefficient k to this number of cycles as indicated
by curve 2.

For cos

ϕ = 0.3: k = 0.6

The electrical durability therefore becomes:

Zelio Control - industrial

3-phase supply control relays RM4 T

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.

2222 Monitoring rotational direction of phases and detection of complete failure
of one or more phases (RM4 T all models):
26When 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.
26If one or more of the phases have failed or if the rotational direction is incorrect,
the relay is not energised at switch-on.
26In 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).
26In 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.
26The absence of a phase is signalled, on RM4 TR and RM4 TA, by illumination of
LED “P”.

2222 Overvoltage and undervoltage detection (RM4 TR):

26In normal operation, the relay is energised and LEDs "U" and "R" are illuminated.

26If 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.

26When 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.
26A 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.
26In all cases, in order to be detected, the duration of the overvoltage or undervoltage
must be greater than the measuring cycle time (80 ms).

3-phase supply control relays RM4 T

2222 Undervoltage detection only (RM4 TU)

26In normal operation, the output relay is energised and the yellow LED is
illuminated.
26If 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

2222 Detection of phase asymmetry (RM4 TA)

26In normal operation, the output relay is energised and the yellow and green LEDs
are illuminated.
26In 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

3 only).

26The 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.

Voltage measurement relays RM4 U

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

3 or selector on “>” for model

RM4 UA3

3) :

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

3 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.

2222 Functions

2 Overvoltage control

2 Undervoltage control

Note: the measurement ranges can be extended above 500 V by adding a resistor,
see page 3/103.
The measurement range on

4 supply can be extended by means of a voltage

transformer, the secondary of which is connected to the measuring terminals of the
corresponding RM4.

1 Adjustments:

2 Adjustment of function and timing range, switch

4

:

- determine the timing range, immediately greater than the time required; in the
above example 30 s,
- determine whether overvoltage or undervoltage detection is required; in this
example, undervoltage,
- position switch

< 30.
2 Fine adjustment of time delay:
Depending on the max. range setting displayed at

4

(in the above example: 30 s)

use potentiometer

3

to set the required time delay as a % of value

4

.

In the above example, the required time = 20 s therefore :

2 Set the voltage threshold setting potentiometer

as a percentage of the maximum

value of the measuring range selected when wiring.
In the above example: wiring B2-C, max. value of measuring range = 50 V, therefore:

2 Set the hysteresis

Current measurement relays RM4 J

The supply voltage is connected to terminals A1-A2.
The current to be monitored is connected to terminals B1, B2, B3 and C. See diagram
below.

Hysteresis is adjustable between 5 and 30 %: for overcurrent h = (IS1 - IS2) / IS1,
for undercurrent h = (IS2 - IS1) / IS1.
A measuring cycle lasts only 80 ms, which allows rapid detection of changes in
current.

Relay set for overcurrent detection (RM4 JA01 or selector on “>” for model
RM4 JA3

3).

If the current is > the setting threshold IS1, the output relay is energised with or
without a time delay, depending on the model. When the current returns to a value
IS2 below the threshold, depending on the hysteresis setting, the relay is
instantaneously de-energised.

Relay set for undercurrent detection (selector on “<”, model RM4 JA3

3 only).

If the current is <, the setting threshold IS1, the output relay is energised with or
without a time delay, depending on the model. When the current returns to a value
IS2 above the threshold, depending on the hysteresis setting, the relay is
instantaneously de-energised.

1 Adjustments:

2 Adjustment of function and timing range, switch

:

- determine whether overcurrent or undercurrent detection is required; in this
example, overcurrent,
- determine the timing range, immediately greater than the time required; in this
example 10 s,
- position switch

4

according to the above 2 criteria; in this example, switch

4

on > 10.

2 Fine adjustment of time delay:
Depending on the max. range setting displayed at

4

(in the above example: 10 s) use

potentiometer

3

to set the required time delay as a % of value

4

.

In the above example, the required time = 5 s therefore:

2 Set the current threshold setting potentiometer

1

as a percentage of the maximum

value of the measuring range selected when wiring.
In the above example: wiring B3-C, max. value of measuring range = 15 A, therefore:

2 Set the hysteresis

2

as a % of the threshold value; in this example:

1 d.c. or a.c. supply
Simply connect a resistor “Rs” to terminals B1-C (or B2, B3-C) on the measuring
input.
The relay energisation threshold will be towards the middle of the setting
potentiometer range if the value of Rs is in the region of:

1 Application:
Use of relay RM4 JA31

33 (10 to 100 mA).

Connection B2-C to measure a threshold of 1 A, knowing that Ri = 10

Ω

for this rating

and that Im = 100 mA.
The value of Rs will be:

= 0.526

Ω

P = (1 -

)

2

x 0.526 i.e. 0.47 W

Select a resistor Rs capable of dissipating at least twice the calculated value, i.e.
1 W for this example, in order to limit temperature rise.
On an a.c. supply, it is also possible to use a current transformer.

Liquid level control relays RM4 L

Functions

These devices monitor the levels of conductive liquids.
They control the actuation of pumps or valves to regulate levels and are also suitable
for protecting submersible pumps against running empty, 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 flap on their front face to avoid any accidental
alteration of the settings. This flap can be directly sealed.

1 Compatible liquids:

2 spring, town, industrial and sea water,

2 metallic salt, acid or base solutions,

2 liquid fertilizers,

2 non concentrated alcohol (< 40 %),

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

1 Non-compatible liquids:

2 chemically pure water,

2 fuels, liquid gasses (inflammable),

2 oil, concentrated alcohol (> 40 %),

2 ethylene, glycol, paraffin, varnish and paints.

Zelio Control - industrial
measurement and control relays

Liquid level control relays RM4 L

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:
1 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.
1 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:
1 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).
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

1 Select the empty /fill function according to the sequence to be performed.

1 If necessary, set potentiometer

1

to minimum (time delay).

1 Set potentiometer

2

to minimum; on RM4-LA, select the lowest sensitivity range

using potentiometer

4

(5

or 5

).

1 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.
1 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

1 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

.

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.

1 Controlling the levels of conductive liquids

1 Regulation of two thresholds:

2 minimum,

2 maximum.

1 Emptying function.

1 Plug-in, 8 or 11-pin.

1 Sensitivity adjustable from 5 kΩ to 100 kΩ.

Operating principle

Control 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.

Regulation of two levels, minimum/maximum

Emptying control

Connection scheme

For RM 84 870 807 (special 11-pin base fitting), pin 5 must be connected to “a”

Plug-in liquid level control relays RM 84 870,
combined fill/empty functions

For RM 84 870 808 (special 11-pin base fitting), pin 5 must be connected to “a”
(maximum) and pin 7 must be connected to “c” (common).

1 Controlling the levels of conductive liquids.

1 Combined fill/empty function.

1 Combined regulation of emptying a well and filling a
tank.
1 Plug-in, 11-pin.

1 Output relay state indication LED.

1 Sensitivity adjustable from 5 kΩ to 100 kΩ

Operating principle

Combined fill/empty function

The output relay changes state when the level of the liquid in the tank 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.

When the level of the liquid in the well reaches the minimum level probe, the pump
stops.

If, on energisation or after a power cut, the maximum level probe in the tank is above
the liquid level, reset the device by pressing button BP.
