Ideal for applications such as industrial processes, automation and motor starters, RTW timing relays switch an output contact based on a selected function and time. These relays are available in many timing ranges, adjustable from 0.1 second to 150 hours, with 9 different functions.

RPW monitoring relays are a competitive choice of voltage monitoring for protection against the most common types of electrical failures. Voltage monitoring in electrical installations is very important for reasons: phase loss, overvoltage, phase sequence and undervoltage. Phase loss and overvoltage can cause machinery and motors to overheat reducing their lifetime. Phase sequence inversion can cause machinery to run in the wrong rotating direction, and undervoltage may occur causing machinery to run in an undefined range. With five different functions, the RPW series is ideal to be used in motor control applications.

The WEG Level Relays are electronic control devices that enable the monitoring and automatic adjustment of the level in electric current liquid conductors. Widely used in reservoir automation, the RNW relays can be used in several applications as the prevention of dry pumps, tank overflow, activation of solenoids or alarms.

ERWT - Multifunction Timing RelaysWEG multifunction timing relays have eight timing functions included in a single relay. With two different models it is possible to achieve up to 16 functions. These two product references have the most commonly used timing functions in the market. The ERWT has an SMPS (Switch Mode Power Supply) that can operate in a wide voltage range from 24 up to 240 V ac/dc.

It is possible to choose one of the eight functions desired in each relay reference using the front selector switches. The required time selection is made in a quick and easy way, through the front switches. The ERWT allows selection from 0.1 second up to 10 days through two selector switches in front of the relay. The first selector switch is used to set the reference with absolute values and the other to define the multiplier to set the required value accurately. The ERWT line is an excellent choice to reduce the stock keeping unit and increase product applications on site.

Timing relays have two output SPDT (Single Pole, Double Throw) contact types that have a visual indication through two red LEDs, which identify the state relay outputs. Indication of energized relays is made through the activated green LED that flashes when the timing is in progress.

To facilitate assembly all ERW line were developed with a width of 22.5 mm, allowing compact combinations of motor starters. These relays can be easily assembled on panels using 35 mm DIN rails or screws, with PLMP adaptors for fixing relays on mounting boards.

Overview

ERWM - Multifunction Monitoring RelaysThe ERWM line of WEG multifunction monitoring relays was created for low-voltage networks on three-phase SMPS that can operate in a wide voltage range from 208 to 480 V ac (50/60 Hz). The voltage range is selectable through a front switch that defines the voltage level the relay will monitor. A frontal green LED gives a visual indication that the relay is connected and monitoring the network.

There are five different functions integrated into a single relay that can be defined through the front switches, allowing the user to select the level of protection required and the time delay to operate. It is possible to monitor failures of phase loss, phase sequence, undervoltage and overvoltage, unbalance and neutral detection to protect three-phase systems using the Multifunction Monitoring Relays.

ERWM relays have an SPDT (Single Pole, Double Throw) output contact type which indicates its status of output contact via a red LED. Additionally, there is a bicolor LED that indicates the status of the functions: constant green indicates no faults, flashing green indicates time count and flashing red indicates fault occurred.

The RTW multi timing relay has two front selectors which have to be set in order to define the right timing.

First, the user needs to select the time scale through the time scale selector.

The other front selector is used to select the multiplier. The timing is the result of the multiplication of these 2 values.

Note: At each timing adjustment of the multi timing relay, the user needs to reset the product. Changes of the timing are not effective when the relay is timing.

The ERWT multifunction relay also has 2 front selectors to adjust the required timing from 0.1s to 10 days.For those functions available in the MF1 model it is necessary to set 1 timing while in the MF2 model, the customer needs to set 2 timings.

Note: The function needs to be selected before energizing the relay. Changes of the timing are not effective when the relay is timing.

Monitoring Relays

WEG RPW Relays are electronic devices that protect three-phase systems against phase loss or selectable neutral loss (RPW FF), phase sequence inversion (RPW SF) or both of the functions integrated into the same product (RPW FSF). Whenever there is failure in the three-phase system, the relay will work to interrupt the motor of process operation to be protected. Designed in accordance with international standards, the RPW Monitoring Relays offer a compact and competitive solution, with 22.5 mm wide housing for assembly on 35 mm DIN rail.

The Phase Sequence Relay is designed to protect three-phase systems against phase sequence inversion (L1-L2-L3). Functioning: on connecting the relay to the supply with the phase sequences correctly connected, the output relay switches the contacts to operation position (closing terminals 15-18) and the red LED turns on. When a phase sequence inversion occurs, the output contacts will become de-energized (opening 15-18) and the red LED will turn OFF.

RPW FF (Neutral Not Selected) The Phase Loss Relay is designed to protect three-phase systems against phase loss with feedback.Functioning: directly connected to the supply to be monitored, feeding the 3-phases with phase amplitude within the selected limits, the output relay switches the contacts to operation position (closing terminals 15-18) and the red LED switches ON. When loss occurs in one of the phases in relation to the others to a value below the percentage limit selected through the sensitivity adjustment DIAL (monitoring against motor ghost phase) the output contact (opening 15-18) will become de-energized and the red LED indicating system running will switch OFF.

RPW-FF - Phase Loss

RPW FF (Neutral Selected)Designed to protect three-phase systems with neutral.Functioning: In the same product, a bridge must be provided between terminals A and B for neutral monitoring. The relay will perform the same monitoring for phase loss and will also monitor the voltage in neutral, which must be connected. When this value exceeds 20 V, there will be output de-energization (opening 15-18).

Note: When a motor is monitored, the current of the remaining phases increases generated by a phase loss, which will cause motor overheating. Winding with armature voltage works as a voltage generator, called “ghost phase”. The RPW FF will protect the motor in this situation.

Functioning: directly connected to the supply to be monitored, supplying the 3-phases and the phase amplitude to be within the selected limits and in the correct sequence, the output relay switches the contacts to the work position (closing terminals 15-18) and the red LED will switch ON. When phase loss or reversion occurs, the output contacts (opening 15-18) become de-energized and the red LED indicating system running will switch OFF.

RPW FSF (Neutral Selected)In the same product, a connection must be made between terminals A and B for neutral monitoring. This way, the relay will perform the same monitoring for phase loss and balancing and will also monitor the voltage in neutral, which must be connected. When the voltage at neutral exceeds 20 V, value that considers unbalanced loads, there will be output de-energization (opens 15-18).

RPW-SS - Undervoltage and Overvoltage

The WEG RPW SS Relay is designed to protect three-phase systems against under or over voltage and phase loss. Functioning: directly connected to the 3-phases to be monitored (L1, L2 and L3) and being the phases amplitude within the sensitivity limits adjusted on the front scales, the relay switches the contacts to the operation position, (closing terminals 15-18) and the red LED will switch on. When any failure occurs in the system causing under or over voltage or even phase loss relay de-energization will occur (opening terminals 15-18) protecting the monitored equipment and the red LED turns OFF.

Electronic Relays24

The RPW-PTC relay is an electronic device used for protection against high temperatures on machines such as motors and generators. The temperature measurement is given by a PTC detector (usually resistors in series) which increase its resistance depending on the temperature where it is installed.Designed in accordance with international standards, the RPW PTC offers a safe and compact solution, with standardized 22.5 mm boxes for assembly in DIN rail 35 mm.Operation: the PTC relay measures the total resistance of the PTC detectors assembled on the motor/generator windings. When the temperature reaches the threshold value, this resistance value rapidly increases and the relay switches OFF its output contacts. The relay will be able to reset only when the temperature goes down to normal values. Additionally, the WEG PTC relay provides PTC detector testing feature. In case of failure of the PTC detectors, the frontal green LED will be flashing. This characteristic indicates that the PTC detectors are either open or in short-circuit condition (20 Ω or less).

Main applications:

g Heavy duty starting g Variable speed drives g High ambient temperature g Frequent switching g Inefficient or insufficient cooling

ERWM - Multifunction Monitoring Relays

ERWM-VM1 / VM2The ERWM is a relay design for low networks with three phase supply voltage in order to monitor the voltage and connecting the switchgear provided it is within the user selected parameters. Whenever there is a fault condition the relay will change its output to interrupt the motor operation or supervised process.

InstallationThe ERWM relay is directly connected to power grids through the L1, L2 and L3 terminals that monitoring three phase system. In those cases, when the neutral is availability it can be connected to the relay to detect the availability of this conductor in the power system.

OperationWhen the voltage connected to the L1, L2 and L3 terminals is according the the selected parameters, the output relay is connected (closed contact 15-18). If the supply voltage monitored is falling outside the defined operating range, the output relay (opening of contact 15-18) is disconnected. The outputs relay reconnects when the voltage back to the selected levels.

Level Relays - RNW

The WEG Level Relays are electronic control devices that enable the monitoring and automatic adjustment of the level in electric current liquid conductors. Widely used in reservoir automation in general, the RNW relays can be used in several applications such as the prevention of dry pump operation, monitoring against filling tank overflow, activation of solenoids or alarms / lighting.The operating principle is based on the measuring of the electrical resistance of the reservoir liquid through an assembly of electrodes that work as liquid presence / absence sensors. To optimize their performance, the relay has a sensitivity DIAL enabling the electronic circuit to be adjusted to the liquid resistance.Available in 2 distinct functions, RNW EN filling and RNW ES draining, the relay offers digital electronics that provide high precision, repeatability and noise resistance. The supply system is isolated from the electronic circuit therefore ensuring greater user safety. Designed in accordance with international standards, the RNW offers a safe and compact solution, in 22.5 mm wide housing for assembly on 35 mm DIN rail, with 1 output with NO/NC reversable contact and an wide voltage supply range of 100-240 V ac/ V dc.

Available in the following functions: g RNW EN → Filling g RNW ES → Draining

Selection

FunctioningThe electrodes are fixed in the reservoir according to desired levels for control, minimum or maximum, and the reference electrode (C) must be positioned in the lower part, below the other electrodes, maximum level electrode (Max) and inimum level etectrode (Min). When the system is energized an alternating current (the AC current minimizes the electrolysis and increases the life span of the electrode) is applied to the reference electrode, once the liquid comes into contact with the level electrodes a path is established for the circulation of electrical current between the electrodes. An electronic current compares the current and according to the chosen model (RNW ES or RNW EN) a logic will occur that switches the relay output contacts. The electrodes are available in 2 models, shaft (EHW) or pendulum (EPW), the difference between them is the way of fixing. In order to adapt the several applications the RNW is available in two distinct functions, draining and filling. Note: the EHW can be fixed both horizontally and vertically.

Controls 2 levels using the 3 electrodes, the reference electrode (C), the maximum level electrode (Max) and the minimum level electrode (Min). Once supplied the RNW ES checks the liquid level in the reservoir, with this being in contact with the Max level electrode, the relay will become energized (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 switch to rest status (terminals 15-18 open) and will thus remain until the liquid enters into contact again with the Max level electrode, restarting the process. If there is a relay supply failure when resupplying the RNW ES verifies the liquid level and restarts its initial logic.

RNW ES (Draining)

Controls 2 levels using the 3 electrodes, the reference electrode (C), the maximum level electrode (Max) and the minimum level electrode (Min). Once supplied the RNW EN monitors the liquid level in the reservoir, with the electrode being uncovered at minimum level Min, the output relay will become energized (terminals 15-18 closed) causing the liquid level to rise. When the reservoir liquid covers the Max level electrode, the relay goes into a state of rest (terminals 15-18 open) and thus remains until the Min level electrode is discovered again. If there is a relay supply failure when resupplying the RNW EN monitors the liquid level and restart its initial logic.

Applications

Sensitivity AdjustmentLiquid resistance can vary according to the resistance of the liquid in question and the position of the electrodes. To adapt the relay 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 in 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 of de-energization. If this does 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 has status indicating LEDs, as shown on the right:
