Zelio Control Relays
Near Field Communication and conventional
Control Relays
Zelio Control Relays
Zelio Control relays monitor and detect abnormal operating conditions concerning
phase, current, voltage, frequency, speed, or temperature. The relays inform users
of abnormal conditions, and allow them to initiate the necessary corrective actions
before serious and costly breakdowns can occur. By monitoring energy network
statuses, they enable both electrical and mechanical load control.
RM17T, RMNF22, RM35L, RM17J Zelio Control Relays
They are suitable for a wide range of applications:
b Hoisting: construction cranes, harbor cranesb Packaging: motor voltage, current overloadb Lifts: construction lifts, passenger lifts, escalatorsb Textile: motor voltage, current overloadb Water: liquid level on water tank at water and waste water recycling plant
Depending on the product model, control relays are categorized into 8 product
families:
b 3-phase controlb Current controlb Voltage controlb Frequency controlb Speed controlb Lift temperature controlb Level controlb Pump control
Zelio Control relay functions
Monitoring
Control relays monitor physical and electrical values. They measure variable signals
such as phase (presence, sequence and symmetry), voltage, current, and
frequency. They also control liquid levels and process operating rates.
Informing
Control device outputs provide users with electrical information. In addition, setting
faults are signaled by simultaneous ashing of all LEDs.
Protecting
Integrated in the control circuits of automated systems, they enable automatic
shutdown management and provide fault information, thus protecting the equipment.
Managing
When the power is switched on, the control relays are inhibited to enable correct
measurement circuit setting. The outputs operate with positive logic, the contact or
contacts being closed under normal conditions and opening as soon as a fault or
power supply loss is detected.
Commissioning
When the diagnostic button is used, the downstream circuit can be closed
immediately without sending a fault input signal to the relays. This shortens the
testing time during commissioning and troubleshooting.

This conguration is considered when relay RM35TM250MW is energized.
b Set the switch to the required operating mode:
v Temperature control without memory
v Temperature control with memory
b On energization, placing the switch in one of the ve intermediate positions holds the relay in the open contact state and the detected error
is signaled by simultaneous ashing of the LEDs.
b The position of the mode selector switch is taken into account on energization.b Any modication of its position during operation has no eect - the active conguration may therefore be dierent from that indicated by the

Operating principle
Voltage control relays RM17UAS (except
RM17UAS15315M) and RM17UBE monitor:
b Voltage of 1-phase and DC supplies
b RM17UASpp relays support two operating modes:
v Overvoltage or undervoltagev Fault memory selected or not b An adjustable time delay, on crossing the thresholds,
provides immunity to transients, and helps prevent
spurious triggering of the output relay
b Fault signaling is by LED
RM17 UAS14/UAS15/UAS16 (except RM17UAS15315M)
The operating mode is determined by a switch:
b Undervoltage with or without memory
b Overvoltage with or without memory
The position of the conguration switch and the operating mode is read by the product on energization:
b If the conguration switch is set to an unacceptable position, the product detects a fault, the output relay stays open and the LEDs ash to
indicate the position error.
b If the switch position is changed while the device is operating, all the LEDs ash, but the product continues to operate normally with the
function selected at the time of energization preceding the change of position.
b If the conguration switch is returned to the original position selected prior to the last energization, the LEDs return to their normal state.

The undervoltage or overvoltage threshold value is set by a graduated potentiometer clearly indicating the voltage Un to be monitored. The
hysteresis is adjusted by a potentiometer graduated from 5…20% of the threshold setting. The hysteresis value must not exceed the limit
values of the measuring range.

These relays operate in window mode where they check that the controlled voltage

potentiometers clearly indicating the voltage Un to be monitored. The hysteresis is
xed at 3% of the threshold setting.
b If the controlled voltage 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 the R LED goes out. During the time delay, this LED ashes.
b 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.
b On energization of the device with a detected measured fault, the relay stays open.
Note:
Tt: time delay after crossing of the threshold
If the controlled voltage falls below the threshold (165 V a), the output relay

1 Conguration: selection of operating mode <I (undercurrent), >I (overcurrent),
>I> (overcurrent and undercurrent), MEMORY - NO MEMORY (with or without
memory)
2 Current threshold setting potentiometer I%
3a Hysteresis adjustment potentiometer Hys
3b Hysteresis/overcurrent and undercurrent window mode adjustment
Current control relays monitor the current of 1-phase
and DC supplies.
An adjustable time delay on threshold crossing provides
immunity to transients, helping prevent spurious
triggering of the output relay.
RM22JA●1MR/RM35JA32M●
The operating mode is determined by the user:
b Undercurrent with or without memory
b Overcurrent with or without memory
The position of the conguration switch and the operating mode is read by the product on energization:
b If the conguration switch is set to an unacceptable position, the product detects a fault, the output relay stays open and the LEDs ash to
indicate the position error.
b If the conguration switch position is changed while the device is operating, all the LEDs ash, but the product continues to operate normally
with the function selected at the time of energization preceding the change of position.
b If the conguration switch is returned to the original position selected prior to the last energization, the LEDs return to their normal state.
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.

b The undercurrent or overcurrent threshold values are set by means of two
graduated potentiometers clearly indicating the I to be monitored. The hysteresis
is xed at 5% of the threshold setting.
b If the controlled current 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…30 s),
the output relay opens and the R LED goes o. During the time delay, this LED
ashes.

Zelio Control Relays
Liquid level control relays
RM22LA and RM22LG
Operating principle
Liquid level control relays are designed to measure and control the levels of
conductive liquids by means of resistive probes.
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 AC current runs across the probes.
A selector switch on the front panel allows selection of the required function and the
sensitivity range. Control of a single level can be achieved by using the second selector switch. In this case, the Max. level probe stays up in the air and an adjustable
time delay avoids any wave eect.
tank is either emptying or lling.
RM22LA and RM22LG
A selector switch on the front panel of these relays allows selection of the required sensitivity range and the empty or ll function. A second
switch allows selection of the number of levels (1 or 2) and the type of time delay in the case of level 1 mode. The position of these
conguration switches is taken into account on energization.
b If the conguration switch is set to an unacceptable position, the product detects a fault, the output relay stays open, and the LEDs ash to
signal the position error.
b If the conguration switch position is changed while the device is operating, all the LEDs ash, but the product continues to operate normally
with the function selected at the time of energization preceding the change of position.
b If the conguration switch is returned to the original position selected prior to the last energization, the LEDs return to their normal state.
Both products activate their output relay when a

Operating principle
Control relays RM35LM and RM35LV are
designed to control the levels of:
b Conductive liquid for RM35LM
(measures the levels by resistive probes)
b Any other material for RM35LV
(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 AC current runs across the probes.
A selector switch on the front panel allows selection of the required function and the
sensitivity range. Control of a single level can be achieved by using the second
selector switch. In this case, the Max. level probe stays up in the air and an
adjustable time delay avoids any wave eect.

Operating principle
RM35LM33MW
Relay RM35LV measures the levels by means of discrete sensors. These two products activate their output relay when a tank is either emptying
or lling.
b A green Un LED indicates that the supply is on.
b A yellow R LED indicates the state of the output relay.
b A yellow Tt LED indicates that timing is in progress.
b The green and yellow LEDs ash to indicate an unacceptable setting position.
A selector switch on the front panel of these relays allows selection of the required sensitivity range and the empty or ll function. A second switch allows
selection of the number of levels (1 or 2) and the type of time delay in the case of level 1 mode.
The position of these conguration switches is taken into account on energization.
b If the conguration switch is set to an unacceptable position, the product detects a fault, the output relay stays open, and the LEDs ash to
signal the position error.
b If the conguration switch position is changed while the device is operating, all the LEDs ash, but the product continues to operate normally
with the function selected at the time of energization preceding the change of position.
b If the conguration switch is returned to the original position selected prior to the last energization, the LEDs return to their normal state.

Pump control relay RM35BA10 can operate
on a 1-phase or 3-phase supply and
incorporates 3 functions in a single unit:
b Current control
b Phase presence control (in 3-phase mode)
b Phase sequence control (in 3-phase mode)
These relays have two operating modes which are designed to control a pump via
two external signal inputs (Y1 and Y2). These two signal inputs are controlled by
volt-free contacts.
Control signal inputs Y1 and Y2 can be connected to:
b A level sensor
b A level relay
b A pressure sensor
b A pushbutton, etc.
Fault signaling is by LEDs with dierentiation of the reason for the fault.

Speed control relay
RM35S
Operating principle
Relay RM35S0MW monitors the speed (rate, frequency) of a process
(conveyor, conveyor belt, etc.) using discrete sensors:
v 3-wire PNP or NPN proximity sensorv 0-30 V voltage inputv NAMUR proximity sensorv volt-free contact
It can be used for monitoring underspeed or overspeed.
RM35S0MW
The control relay measures the speed as follows:
v The cycle of the process being monitored is a series of impulses characterized by a two-state signal: high and low. v The speed is obtained by measuring the period of this signal, from the detection of rst change of state (either rising or falling edge).v Digital processing of the signal allows the disparity between the signals to be calculated.v On energization or after appearance (or reappearance) of the sensor signal, detection (characterization) of the signal requires processing
of one or two periods. During this time, control is inoperative.
The operating modes are selected by using the switch:
v Underspeed without memory
v Underspeed with memory
v Overspeed without memory
v Overspeed with 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 (xed at 5% of the threshold setting).
When power is restored, after a break having lasted at least 1 s, the relay is in the
“closed” state during the time delay and stays in that state for as long as the speed
remains higher than the threshold.
When relay RM35S has been congured in “memory” mode, if underspeed is
detected, the output relay stays in the “open” state, irrespective of any further
changes in the process speed.
It will not be able to return to the “closed” 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 “open” state.
Relay RM35S can also be reset by a power break (at least 1 s); the relay then returns
to the “closed” state for at least the duration of the time delay, irrespective of the
process speed.

RM35S
On energization, to allow the process being monitored to reach its nominal
operating speed, relay RM35S is inhibited for a time delay adjustable from
0.6…60 s. This time delay can be adjusted (shortened or lengthened) during
inhibition.
Relay RM35S can also be inhibited by closing of contact S2: on starting, for
example, if the process run-up to speed time is greater than 60 s, or at any
time during operation.
Whether it results from a starting inhibition time delay or closing of S2,
inhibition keeps the output relay in the “closed” position and is signaled 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 from the
end of inhibition).
Inhibition should last as long as is necessary for the product to detect at least 2
periods.
When the signal has not been ‘characterized’ by the end of the inhibition

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

Threshold
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 (xed at 5% of the threshold setting).
When power is restored to relay RM35S, after a break having lasted at least
1 s, the relay is in the “closed” state during the time delay and stays in that
state for as long as the speed remains lower than the threshold.
When relay RM35S has been congured in “memory” mode, if overspeed is
detected, the output relay stays in the “open” state, irrespective of any further
changes in the process speed.
It will not be able to return to the “closed” 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 “open”
state.
Relay RM35S can also be reset by a power break (at least 1 s); the relay then
returns to the “closed” state for at least the duration of the time delay,
irrespective of the process speed.

RM35S
On energization, in order to allow the process being monitored to reach its nominal
operating speed, relay RM35S is inhibited for a time delay adjustable from 0.6…60 s.
This time delay can be modied (shortened or lengthened) during inhibition.
Relay RM35S can also be inhibited by closing of contact S2: on starting, for
example, if the process run-up to speed time is greater than 60 s, or at any time
during operation.
Whether it results from a starting inhibition time delay or closing of S2, inhibition
keeps the output relay in the “closed” position and is signaled 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 from the end of inhibition).
Inhibition should last as long as is necessary for the product to detect at least 2 periods.
When the signal has not been ‘characterized’ by the end of the inhibition period, the
“inhibition” LED ashes for as long as speed measurement is impossible.
It is also possible to inhibit relay RM35S at any time, during operation, by closing S2.

After a delay on pick-up after energization, and for as long as the temperature monitored
by the PT100 probe remains between the two thresholds set on the front panel, the
output relay is closed and the yellow LEDs are on.
When the temperature crosses one of the threshold settings on the front panel (high or
low threshold), the time delay set on the front panel (Tt) is activated. The yellow LED
θ
corresponding to the threshold crossed (low or high) ashes.
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 xed hysteresis.
If the PT100 probe is incorrectly wired (missing or short-circuited) the relay is open and
the 3 LEDs ash.
Note: Tt: time delay after crossing of the temperature threshold (adjustable on front panel)

fter a delay on pick-up after energization, and for as long as the temperature monitored
by the PT100 probe remains between the two threshold settings on the front panel, the
temperature relay R1 is closed.
When the temperature crosses one of the threshold settings on the front panel (high or
low threshold), the time delay set on the front panel (Tt) is activated. The yellow
temperature LED ashes. 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 xed hysteresis.
The device also monitors the correct sequence of phases L1, L2, and L3 of the 3-phase
supply and total phase loss, even in the case of phase regeneration (< 70%).
After a delay on pick-up after energization, and for as long as phase presence and
phase sequence are correct, relay R2 and the “phase” LED are On. When a fault
appears, the “phase” relay opens and the “phase” LED instantly goes out (response
time on appearance of a fault).
When the fault disappears, the phase control relay and LED are activated (response
time on disappearance of a fault).
If the PT100 probe is incorrectly wired (missing or short-circuited) relay R1 is open and
LED R1 ashes.
Note: Tt: time delay after crossing of the temperature threshold (adjustable on front panel)
