RPW protection relays are a competitive choice for monitoring voltage againstthemostcommontypesofelectricalfailures.Monitoringvoltagesin electric installations are important for several reasons. Overvoltage, or phase loss can overheat machinery and motors, thus reducing their lifetime. Phase sequence inversion can cause machinery to run in a wrong way,thendestroyingtheentiresystem;andundervoltagemayoccurcausing machinery to run in an undefined range, which could cause some parts of a system to run properly while others cease operating.With five different functions, the RPW series are ideal to be used in electric motor control panel applications.

These electronic control devices enable monitoring and automatic level adjustment of an electrical current liquidconductor. Widely used in general reservoir automation,theRNWseriesrelayscanbeusedinapplicationssuchasprevention of dry pumps, operation, monitoring against fillingtank overflow, activation of solenoids or alarms. This seriesoffers digital electronics that provide high precision,repeatability, and noise resistance. The supply system is isolated from the electronic circuit, therefore ensuring greateruser safety.

The operating principle is based on measuring the electricalresistance of the liquid through electrodes for presence or abscence. To optimize preformance, the relay has a dialfor sensitivity to the liquid's resistance being measured.

RTW RE (ON - Delay) – Connecting a supply voltage on terminals A1-A2 / A3-A2 the selected time delay begins and the

green LED turns on. After the end of the delay time the output relay picks up (red LED turns on) and remains energized until

the supply voltage is removed. This can be repeated as often as required.

Reset: Removing supply voltage resets the time delay and the output.

RTW PE (Impulse On) – Connecting a supply voltage on terminals A1-A2 / A3-A2 (green LED turns on) the output relay picks

up without delay (red LED turns on) and remains energized until the selected pulse time elapse (red LED turns off). This can

be repeated as often as required.Reset: Removing supply voltage resets the time delay and the output.

RTW RD (OFF Delay) – This function requires continuous supply voltage on terminals A1-A2 (green LED turns on) and timing

is controlled by a command contact at terminals A2-B1. If the command contact is energized, the output relay picks up (red

LED turns on) and after the command contact is removed the selected time delay begins. When the selected time elapse the

output relay is de-energized (red LED turns off). This can be repeated as often as required.Reset: Removing supply voltage

resets the time delay and the output.

RTW RDI (OFF Delay with no control command) – Connecting a supply voltage on terminals A1-A2 / A3-A2, the green LED

turns on and the output relay picks up without delay (red LED turns on). If the supply voltage is de-energized, the selected

time delay begins and when this time elapse, the output relay is de-energized (red LED turns off). This can be repeated as

often as required. Reset: Removing supply voltage resets the time delay and the output.

RTW CI (Assymmetric Flasher-Pulse) – Connecting a supply voltage on terminals A1-A2 / A3-A2 the green LED turns on and

the timer starts to pulse with adjustable ON/OFF cycles. The upper dial presets the ON time (red LED turns ON and output

relay picks up) and the lower select the OFF time when the output relay is de-energized.


RTW CIL (Symmetric Flasher - Pulse) – Connecting a supply voltage on terminals A1-A2 / A3-A2 the green LED turns on and

the timer starts to pulse with symmetric ON/OFF cycles.The dial presets a fixed ON time (red LED turns ON and output relay

picks up) and OFF time. Reset: Removing supply voltage resets the time delay and the output.

RTW CID (Symmetric Flasher - Pause) – Connecting a supply voltage on terminals A1-A2 / A3-A2 the green LED turns on

and the timer starts to pulse with symmetric OFF/ON cycles.The dial presets a fixed ON time (red LED turns ON and output

relay picks up) and OFF time. Reset: Removing supply voltage resets the time delay and the output.

RTW ET (Wye-Delta) – Connecting a supply voltage on terminals A1-A2 / A3-A2 the output relay for the wye-connection

picks up and the adjusted time starts (red LED turns ON). When the start-up time elapses, a fixed star-delta changeover

time of 100 ms starts and after this star-delta changeover time elapses the output relay for the delta-connection picks up

and stays energized until the supply is disconnected.

The sensitivity adjustment (threshold) is made by

the DIAL located on the front of the relay.

It ranges from 70% to 90%, which defines the

balance for one phase related to the others.

RPW FSF (without neutral selection) The Phase Sequence and Phase Loss Relay -

RPW FSF - is used to monitor three-phase networks against phase loss and incorrect

phase sequence.

Operation: If the phase sequence at the terminals L1-L2-L3 is correct and balanced

with values higher than the selected on the dial, the output relay picks up (close the

15-18 terminals) and the red LED turns ON. In case of an incorrect phase sequence

or a phase fails below the threshold value, the output relay remains in its rest position

(close the 15-16 terminals) and the red LED turns OFF.

RPW FSF (with Neutral selection) The Phase Sequence and Phase Loss Relay - RPW

FSF - is used to monitor three-phase networks and neutral against phase failure and

incorrect phase sequence.

Operation: In the same product, the neutral protection is enabled jumpering the terminals

A and B to monitor the neutral voltage (terminal N). The neutral must be connected to

the protection relay for proper operation.

Note: When one phase fails, connected loads (motor windings, lamps, transformers, coils, etc.) create a feedback voltage at the terminal of the failed phase due to the network coupling. Such phase failure is detected with the RPW FSF.

RPW-SF The Phase Sequence Relay - RPW-SF - is used to monitor three-phase networks against incorrect phase sequence.

Operation: If the phase sequence at the terminals L1-L2-L3 is correct, the output relay picks up (close the 15-18 terminals) and the red LED turns ON. In case of an incorrect phase sequence, the output relay remains in its rest position (close the 15-16 terminals) and the red LED is turns OFF.

RPW FF (without neutral selection) The Phase Loss Relay - RPW FF - is used to monitor three-phase networks against phase failure.

Operation: Connected directly to the supply voltage to be monitored, and connecting the three phases with values above than the selected on the dial, the output relay is energized (close the 15-18 terminals) and turns on the red LED indicating that the system is properly working. In case the voltage falls below the threshold value the output relay is de-energized (close the 15-16 terminals) and the red LED is turns OFF.

RPW FF (with neutral selection)The Phase Loss Relay - RPW FF - is used to monitor three-phase networks and the neutral against phase failure.

Operation: In the same product, the neutral protection is enabled jumpering the terminals A and B to monitor the neutral voltage (terminal N). The neutral must be connected to the protection relay for proper operation.

Assymmetry

RPW-SS The Under and Over-voltage Relay RPW SS is used to monitor maximum and minimum

variations that three-phase power supplies are able to work. The RPW SS also protects the circuit

against phase unbalance (asymmetry) of 20% or higher between phases.

Operation: Connecting the phases L1-L2-L3 with phase amplitudes within the selected values

and assymmetry between them below the threshold (20%), the output relay picks up (close

the 15-18 terminals) and the red LED turns ON. In case of a phase loss, assymmetry between

phases higher than 20% or under and over-voltage, the output relay remains in its rest position

(close the 15-16 terminals) and the red LED is turns OFF.

Available Voltages:24-240Vac 50/60Hz / Vdc - E05

RPW-PTC The Thermistor Relay RPW PTC is used to measure the motor temperature by using

PTC sensor inside of the motor. When the motor temperature rises above the PTC sensor class,

the output relay is de-energized avoiding damages to the motor.

Operation: Connected directly to the supply voltage and in series to the PTC sensor (maximum of

3 sensors), the output relay is automatically energized (close the 15-18 terminals) and turns on

the red LED indicating that the temperature is within acceptable values. If an over temperature

occurs, the probe resistance is rapidly increased and the output relay is de-energized (close the

15-16 terminals) and the red LED turns OFF, remaining on this situation until the temperature

decreases at a normal value. The RTW PTC is able to evaluate if the PTC sensor has a fault (not

caused by an over temperature) or if is not connected (open circuit). In such situations, the green

LED will start flashing.

Applications

Sensitivity Adjustment

Liquid resistance can vary according to the liquid in question and the position of the electrodes. To adapt the electronic circuit to the liquid used, sensitivity must be adjusted through the DIAL located in the front part of the RNW, which has a graded scale without values. To perform the sensitivity adjustment, all electrodes must be submersed into the reservoir liquid and the DIAL positioned at its limit anti-clockwise (less resistance). With the relay energized, the DIAL must be turned clockwise (greater resistance) until the relay output switches its contacts (the red LED must change status). To confirm the adjustment, the reference electrode C must be disconnected and then quickly reconnected, the relay must return to its previous status. If this not happen, a new adjustment must be performed. By doing this, the RNW will be adjusted to the ideal sensitivity point.

Relay Light IndicationsThe RNW Level Relay is equipped with indicator LEDs as shown on the right:

Controls 2 levels using 3 electrodes: the reference electrode (C), the maximum level electrode (Max) and the minimum level electrode (Min). Once powered, the RNW ES start monitoring the liquid level in the reservoir. With the liquid being in contact with the Max level electrode, the relay will energize (terminals 15-18 closed), causing the reservoir liquid level begin to drop. Once the Min level electrode is uncovered by the liquid the relay will energize (terminals 15-18 open) and will remain energized until the liquid enters into contact again with the Max level electrode, restarting the process. If there is a supply failure, the RNW ES will restart its initial logic.

RNWES(Draining)

Controls 2 levels using 3 electrodes: the reference electrode (C), the maximum level electrode (Max) and the minimum level electrode (Min). Once powered, the RNW EN start monitoring the liquid level in the reservoir. With the electrode being uncovered at minimum level Min, the output relay will energize (terminals 15-18 closed) causing the liquid level to rise. When the reservoir liquid covers the Max level electrode, the output realy de-energize (terminals 15-18 open) and remains de-energized until the Min level electrode is discovered again. If there is a supply failure, the RNW EN will restart its initial logic.
