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.

Fault signalling is by LED.

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.

Voltage control relays RM4 U

1 Overvoltage setting potentiometer.2 Undervoltage setting potentiometer.3 Time delay function selector:

4 Potentiometer for setting time delay in seconds.

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

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

If the voltage 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 voltage 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).

t : time delay

FunctionsThese devices are designed for monitoring single-phase voltages.They have a transparent, hinged flap on their front face to avoid any accidental alteration of the settings. This flap can be directly sealed.

Applications� Protection of electronic or electromechanical devices against overvoltage and undervoltage.� Normal/emergency power supply switching.

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

� Undervoltage 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.
