1.2 General InformationATSs are used to protect critical electrical loads against loss of power. The loads utility power source is backed up by a genera-tor power source. An ATS is connected to both the utility and generator power sources and supplies the load with power from one of these two sources. In the event that power is lost from the utility power source, the ATS transfers the load to the generator power source. Once the utility power is restored, the load is auto-matically transferred back to the utility power source (Figure 2).

Figure 2. Typical Load Transfer Switch (Contactor) Schematic.An intelligence system initiates the transfer when the utility power source fails or falls below a preset voltage. An engine start is then initiated by the generator and the ATS transfers to the gener-ator power source when sufficient generator voltage is available. When the utility power source is restored, the ATS automatically transfers back and the generator will shut down after a time delay. In the event the utility power source fails and the generator power source does not appear, the ATS remains connected to the utility power source until the generator power source does appear. Conversely, if connected to the generator power source and the generator power source fails while the utility power source is still unavailable, the ATS remains connected to the generator power source.

ATSs automatically perform the transfer function, and include three basic elements.

1. Main contacts to connect and disconnect the load to and from the source of power.

2. Solenoids to make the transfer of the main contacts from source to source.

3. Intelligence/supervisory circuits to constantly monitor the con-dition of the power sources and thus provide the intelligence necessary for the switch and related circuit operation.

1.2.1 Design ConfigurationThe Eaton Residential ATS is a rugged, compact design that uti-lizes power contactors to transfer essential loads from one power source to another (see Figure 3). The Residential ATS contains suitable mechanical and/or electrical interlock switches to elimi-nate the possibility of connecting the utility service to the genera-tor output. In addition, a manual override lever is provided for the transfer function.

Figure 3. EGS100L24R (100 A).

1.2.2 Load Shed ContactsTwo sets of contacts are available and can be used to control large connected loads on the generator (i.e. air conditioners, hot tubs, etc.). The contacts are rated for 250 Vac, 5 amps maxi-mum.

1.3 Transfer Switch Catalog Number IdentificationATS equipment catalog numbers provide a significant amount of relevant information pertaining to a specific piece of equipment. The Catalog Number Identification Table (see Table 1) provides the required interpretation information.

1.4 Environmental and Operational ConditionsNormally, an ATS is applied indoors in an electrical equipment room. It can also be used for normal outdoor applications (with standard NEMA 3R enclosure) where the equipment is subject to falling rain, freezing temperatures, and 95% humidity (non-con-densing). The ambient temperature range for operation is between -20 and 70C (-4 and 158F).

1.5 Glossary

With respect to their use within this document and as they relate to transfer switch and controller operation, the following terminol-ogy is defined.

AvailableA source is defined as available when it is within its undervolt-age setpoint ranges for the nominal voltage setting.

ConnectedConnected is defined as when the input is shorted by an external contact or connection.

Failed or FailsA source is defined as failed when it is outside of the applicable voltage setpoint ranges for the nominal voltage and for a time exceeding 0.5 seconds after the time delay emergency fail (TDEF) time delays expires.

FailsafeFailsafe is a feature that prevents disconnection from the only available power source and also forces a transfer or re-transfer operation to the only available power source.

Re-TransferRe-transfer is defined as a change of the load connection from the Generator to the Utility.

UtilityUtility is the primary source (normal source, normal power source, or normal).

GeneratorGenerator is the secondary source (generator emergency source, emergency power source, emergency, standby, or backup source).

Utility: Failed or FailsUtility is defined as failed when it is outside of its undervoltage setpoint ranges for the nominal voltage and frequency setting.

SECTION 2: RECEIVING, HANDLING, AND STORAGE2.1 ReceivingEvery effort is made to ensure that the ATS equipment arrives at its destination undamaged and ready for installation. The packing is designed to protect the internal components as well as the enclosure. Care should be exercised, however, to protect the equipment from impact at all times. Do not remove the protective packaging until the equipment is at the installation site and ready to be installed.

When the ATS equipment reaches its destination, the customer should inspect the shipping container for any obvious signs of rough handling and/or external damage that occurred during trans-portation. Record any external and internal damage for reporting to the transportation carrier and to the Eaton sales representative, once a thorough inspection is complete. All claims should be as specific as possible and include the Shop Order and General Order numbers.

A shipping label affixed to the shipping container includes a vari-ety of equipment and customer information, such as General Order and catalog numbers. Make certain that this information matches the other shipping paper information.

Each ATS enclosure is packaged in its own box. Do not discard the packing material until the equipment is ready for installation.

Once the packaging is removed from the shipment, the enclosure door can be opened. A plastic bag of documents will be found in the enclosure. Important documents, such as wiring diagrams and appropriate instruction leaflets are enclosed within the bag and should be filed in a safe place.

2.2 HandlingAs previously mentioned, ATS equipment is packaged in its own box. Protect the equipment from impact at all times and do not double stack. Once the equipment is at the installation site and ready to be installed, the packaging material can be removed. Refer to Section 4 of this manual for specific installation instruc-tions.

2.3 StorageAlthough well packaged, this equipment is not suitable for outdoor storage. The equipment warranty will not be applicable if there is evidence of outdoor storage. If the equipment is to be stored indoors for any period of time, it should be stored with its protec-tive packaging material in place. Protect the equipment at all times from excessive moisture, construction dirt, corrosive condi-tions, and other contaminants. It is strongly suggested that the package-protected equipment be stored in a climate-controlled environment of -20 to 70C (-4 to 158F), with a relative humid-ity of 80% or less. Do not, under any circumstance, stack other equipment on top of an ATS equipment enclosure, whether pack-aged or not.

SECTION 3: EQUIPMENT DESCRIPTION3.1 IntroductionThe Eaton Residential ATS is assembled and tested at the factory. It is designed to be used in conjunction with standby power distri-bution equipment to provide an alternate source of power to criti-cal circuits in the event that the primary power source is interrupted.

This ATS monitors both utility and generator power sources and automatically transfers critical load circuits between the two sources, depending on which source is available. The utility power source is preferred and will remain connected to the switch if it is available.

3.2 Power Panel

The power panel is used for making load, power, and neutral con-nections. The power contactor is mounted on a steel baseplate (Figure 4).

Figure 4. Typical Power Panel for 100 A.

3.2.1 Main Contacts

This ATS incorporates power contactors as the main switching device. The main contacts connect and disconnect the load to and from the different power sources. The power contactor is mechanically interlocked to prevent the two sets of main contacts from being closed simultaneously.IB70-8671 For more information visit: www.eaton.com



3.3 RTC-50 Logic Panel

The RTC-50 is a microprocessor-based transfer switch logic con-trol package. The hardware and software of the controller contain the intelligence/supervisory circuits that constantly monitor the condition of the power sources. It provides the intelligence neces-sary for the operation of the ATS (Figure 5).

Figure 5. RTC-50 Logic Control Panel.

The RTC-50 controller has an operating temperature of -20 to 70C (-4 to 158F).

The controller circuit board is protected by an insulating conformal coating.

The specifications, under normal operating conditions, are as fol-lows:

Tolerance for voltage sensing function: 1% of full scale

4.5 Wiring

4.6 InstallationIn a typical installation for critical loads (see Figure 10), the ATS (1) and the generator (2) are connected to the power supply. The ATS and emergency distribution panel (1) receive utility power from a dedicated breaker in the utility service panel (3). The ATS and emergency panel receive generator power from the generator (2). Power from the utility feeds the utility panel.

Figure 10. Typical Installation of a Residential ATS.

The ATS (1) and generator (2) are connected to the power supply. The automatic transfer switch is located between the generator and the utility panel (3).

When the utility power fails, the ATS will sense the failure, the generator will start, and when sufficient generator voltage is avail-able, the ATS will switch all loads to the emergency panel. All emergency loads will receive power from the generator. A line breaker is required between the generator power source and the transfer switch (see Figure 11). When utility power returns, the ATS will switch all power back to the utility panel and the genera-tor will shut down.

Figure 11. Diagram of a Typical Installation (Critical Loads Only).

4.7 Generator Utility Sensing ConnectionThe generator utility sensing connections are located on the fuse block that is installed at the bottom of the power panel. The utility sensing wires, required for proper generator operation, are con-nected at this point.

Note: Prior to making the generator utility sensing connection to the ATS, set the generator control selector switch to the OFF position to prevent an unwanted generator start. Control wiring, such as the generator utility sensing wires, must be run separately from the power cables.

Use the proper wire size as listed by the generator set (Genset) manufacturer.This ATS is intended for use on generators with built in auto start features. These generators sense, and react to, utility power. Remote starting contacts are not provided in this transfer switch.

WARNINGPOWER CONDUCTORS AND CONTROL WIRING MAY HAVE VOLT-AGE PRESENT THAT CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. DE-ENERGIZE ALL POWER OR CONTROL CIRCUIT CONDUC-TORS BEFORE BEGINNING TO PERFORM ANY WIRING ACTIVITY TO OR WITHIN THE ATS EQUIPMENT.

CAUTIONCHECK THE ATS EQUIPMENT NAMEPLATE FOR RATED VOLTAGE. IT SHOULD BE THE SAME AS THE UTILITY AND GENERATOR LINE VOLTAGES. OPERATING THE EQUIPMENT ON IMPROPER VOLTAGE CAN CAUSE EQUIPMENT DAMAGE.

SECTION 7: MAINTENANCE AND COMPONENT REPLACEMENT7.1 Introduction

In general, ATS equipment is designed to be relatively mainte-nance free under normal usage. However, because of the variabil-

ity of application conditions and the importance placed on dependable operation by this type of equipment, inspection and maintenance checks should be made on a regularly scheduled basis. Since equipment maintenance will consist mainly of keep-ing the equipment clean, the frequency of maintenance will depend, to a large extent, on the cleanliness of its surroundings. If a significant amount of dust or foreign matter is present, a more frequent maintenance schedule should be followed.

It is suggested that visual inspections of the equipment be made on a regular basis, not just during regularly scheduled periods. Always be alert for an accumulation of dirt in and around the structure, loose parts and/or hardware, cracks and/or discolora-tion to insulation, and damaged or discolored components.

Figure 12 is the wiring diagram for the EGS 100 Amp ATS switch.

Note:Only qualified and experienced personnel should attempt any diag-nostic work using this diagram.

WARNINGHIGH VOLTAGES ARE PRESENT IN AND AROUND TRANSFER SWITCH EQUIPMENT. BEFORE INSPECTING OR MAINTAINING THIS EQUIPMENT, DISCONNECT THE LINE POWER FROM THE EQUIP-MENT BEING SERVICED BY OPENING AND LOCKING OUT, IF POSSI-BLE, THE NEXT HIGHEST DISCONNECT DEVICE. FAILURE TO FOLLOW THIS PROCEDURE COULD CAUSE SEVERE PERSONAL INJURY AND/OR DEATH.IB70-8671 For more information visit: www.eaton.com


7.2 ProceduresA suggested maintenance procedure to be followed is outlined in Table 3.

Table 3. Recommended Periodic Maintenance Procedures.STEP ACTION

a. Make the transfer switch equipment safe for inspection and/or maintenance. Disconnect the line power from the equipment being serviced by opening next highest disconnect device. Make certain that any accessory control power is switched off.

b. Inspect the structure area for safety hazards or potential maintenance problems. Inspect the area, especially where the contactor is installed, for any safety hazards, including per-sonal safety and fire hazards. Exposure to certain chemical vapors can cause deterioration of the electrical connections.Inspect for accumulated dirt, loose hardware, or physical damage.Examine the primary insulation for evidence of cracking or overheating. Overheating will show as discoloration, melting, or blistering of the conductor insulation, or as pitting or melting of the con-ductor surfaces due to arcing.Inspect the secondary control connections for damage, and control wiring for insulation integrity.

c. Inspect the contactor for dust, dirt, soot, grease, moisture, or corrosion. Remove dust, dirt, soot, grease, moisture, and corrosion contamination from the surface of the switching device using a dry, soft lint-free cloth, dry soft bristle brush, and vacuum cleaner. Do not blow debris into the contactor. If contamination is found, look for the source and fix the prob-lem.

d. Check for material integrity, uneven wear, discoloration, or loose hardware. Severe material cracking will require replacement and loose hardware will need to be tightened.

e. Check the terminals and connectors for looseness or signs of overheating. Overheating will show as discoloration, melting, or blistering of the conductor insulation.Connections that do not have signs of looseness or overheating should not be disturbed.

f. Exercise the contactor if it is not often exercised while in operation. This will permit the wiping action by the contacts.

If a switching device is used for frequent switching during normal operation, this step can be disre-garded.

1.2 Informacin generalLos ATS son utilizados para proteger cargas elctricas crticas contra prdidas de energa. La fuente de energa del servicio de la carga es respaldada por una fuente de energa del generador. Un ATS es conectado a ambas fuentes de energa, el servicio y el generador, y abastece a la carga con energa de una de estas dos fuentes. En el caso en que la energa de la fuente del servicio se pierda, el ATS transfiere la carga a la fuente de energa del genera-dor. Una vez que la energa del servicio es restaurada, la carga es automticamente transferida de nuevo a la fuente de energa del servicio (figura 2).

Figura 2. Esquema del interruptor (contactor) de transferencia de carga tpico.Un sistema de informacin inicia la transferencia cuando la fuente de energa del servicio falla o cae por debajo de un voltaje prefi-jado. El generador inicia entonces un arranque del motor y el ATS transfiere a la fuente de energa del generador cuando hay dis-ponible suficiente voltaje en el mismo. Cuando la fuente de energa del servicio es restaurada, el ATS automticamente trans-fiere nuevamente, y el generador se interrumpe despus de un tiempo de retraso. En el caso de que la fuente de energa del servi-cio falla y la fuente de energa del generador no aparece, el ATS permanece conectado a la fuente de energa del servicio hasta que la fuente de energa del generador aparece. A la inversa, si est conectado a la fuente de energa del generador y la misma falla mientras la fuente de energa del servicio todava no est dis-ponible, el ATS permanece conectado a la fuente de alimentacin del generador.

Los ATS automticamente realizan la funcin de transferencia, e incluyen tres elementos bsicos.

1. Contactos principales para conectar y desconectar la carga hacia y desde la fuente de alimentacin.

2. Solenoides para hacer la transferencia de los contactos princi-pales desde fuente a fuente.

3. Circuitos de informacin/supervisin para controlar constante-mente la condicin de las fuentes de alimentacin y as pro-

1.2.1 Configuracin del diseoEl ATS residencial Eaton tiene un diseo resistente y compacto que utiliza contactores de energa para transferir cargas esenciales desde una fuente de alimentacin a otra (vea la figura 3). El ATS residencial contiene interruptores entrelazados mecnicos y/o elctricos apropiados para eliminar la posibilidad de conectar el servicio pblico a la salida del generador. Adems, se proporciona una palanca manual para anulacin de automatismo, para la fun-cin de transferencia.

Figura 3. EGS100L24R (100 A).

1.2.2 Contactos para restriccin de cargaDos juegos de contactos se encuentran disponibles y pueden ser utilizados para controlar cargas grandes conectadas al generador (por ejemplo, acondicionadores de aire, jacuzzis, etc.). Los contac-tos tienen una capacidad nominal de 250 V CA, 5 A como mx-imo.

4.6 InstalacinEn una instalacin tpica para cargas crticas (vea la figura 10), el ATS (1) y el generador (2) estn conectados a la alimentacin de energa. El ATS y el panel de distribucin de emergencia (1) reciben energa del servicio de un cortacircuito dedicado en el panel del servicio (3). El ATS y el panel de emergencia reciben energa generadora desde el generador (2). La energa del servicio alimenta el panel del servicio.

Figura 10. Instalacin tpica de un ATS residencial.

El ATS (1) y el generador (2) estn conectados a la fuente de ali-mentacin. El interruptor automtico de transferencia est local-izado entre el generador y el panel del servicio (3).

Cuando la alimentacin del servicio falla, el ATS sensa la falla, el generador arranca, y cuando suficiente voltaje en el generador se encuentra disponible, el ATS cambia todas las cargas al panel de emergencia. Todas las cargas de emergencia recibirn aliment-acin del generador. Un cortacircuitos de lnea es requerido entre la fuente de alimentacin del generador y el interruptor de transfer-encia (vea la figura 11). Cuando la alimentacin del servicio retorna, el ATS cambia toda la alimentacin nuevamente al panel del servicio y el generador se detiene.

Figura 11. Diagrama de una instalacin tpica (cargas crticas solamente).

4.7 Conexin sensora del servicio del generadorLas conexiones sensoras del servicio del generador estn localiza-das en el bloque de fusibles que est instalado en la parte inferior del panel de alimentacin. Los cables sensores del servicio, requeridos para una operacin correcta del generador, se conectan en este momento.

Nota: Antes de realizar la conexin sensora del servicio del generador al ATS, fije el interruptor selector de control del generador en la posicin "OFF" (desconectado) para evitar un arranque no deseado del generador. El cableado de control, tal como los cables sensores del servicio del genera-dor, deben hacerse correr separados desde los cables de alimentacin.

Utilice la medida de cable correcta, tal como est enlistado por el fabricante del equipo generador (Genset).Este ATS est diseado para ser usado en generadores con car-actersticas de auto arranque incorporadas. Estos generadores sen-san y reaccionan a la alimentacin del servicio. En este interruptor de transferencia no se proporcionan contactos de arranque remo-tos.

ADVERTENCIALOS CONDUCTORES DE ENERGA Y EL CABLEADO DE CONTROL PUEDEN TENER VOLTAJE PRESENTE QUE PUEDE CAUSAR SEVERAS HERIDAS PERSONALES O MUERTE.
