Equipment Description
The transfer switch is intended to transfer the entire load of
normal residential installations when used with the
supervisory contacts provided. The load is connected either
to utility power (normal) or home standby power
(generator). The transfer switch monitors utility and
generator voltages and will automatically connect to the
appropriate source of power.
Major components of the transfer switch are a 2 pole double
throw transfer switch, control circuit board, fused utility
terminals and interconnecting wiring. The control board also
has two inputs for current transformers that sense generator
current.
The transfer switch is solenoid-operated from utility or
generator inputs and contains suitable mechanical and
electrical interlock switches to eliminate the possibility of
connecting the utility service to the generator output. It has
ratings capable of switching full utility power into the
residence. In addition, a manual override lever is provided
for the transfer function.
The control circuit board has active circuits sensing utility
and generator voltages. It creates a signal for the generator
start-up, switch transfer, and retransfer when utility is
restored. The control board also contains red and green
LED’s indicating the power sources available and two relay
operated contacts that provide supervisory control of
external loads.

Controls
Other than a Manual Override lever, there are no operator
controls because this is an automatic transfer switch. The
manual override is to be used only by licensed professionals.
Operation
To select automatic transfer operation, do the following:
1. Set service disconnect switch that sends utility power
to transfer switch contactor to “On” position.
2. Set generator’s main circuit breaker to its “On” position.
3. Install 15 Amp fuse in control panel on generator.
4A. If generator is equipped with a system AUTO/OFF
switch, set switch to “AUTO” position.
B. If generator is equipped with a AUTO/OFF/MANUAL
switch, set switch to “AUTO” position.
The system will now be in automatic operation mode.
When the generator is providing power to the transfer
switch, the controller is constantly monitoring generator
power. If the air conditioner is called to run, and there is
sufficient generator power available, the controller will close
contacts “A-A” to air conditioner contactor. Contacts “B-B”
will open before contacts A-A close. If loads are too great for
generator, contacts A-A and/or B-B will open. When air
conditioning is not needed, A-A will open. If enough power is
available, B-B will close.
Testing the Automatic Transfer Switch
Turn the service disconnect feeding the transfer switch
contactor to the “Off” position. The automatic sequence of
the system will follow. To go back to utility power, turn the
service disconnect to the “On” position.
Utility Fail
The Home Standby Generator set senses when utility voltage
is below 70 percent of nominal. Engine start sequence is
initiated after 6 second time delay.
Engine Warm-Up
Time delay to allow for engine warm-up before transfer is
fixed at 20 seconds or 50 seconds with removal of jumper
on control board.
Transfer
Transfer from utility to generator supply occurs after voltage
is above set levels. Minimum engine run time is 5 minutes
after transfer.
Utility Pickup
Voltage pickup level is 80 percent of nominal voltage.
Retransfer
Retransfer from generator to utility supply is approximately
10 seconds after utility voltage supply is above pickup level
and minimum run time is completed.
Engine Cool Down
Engine will run for 60 seconds after retransfer.
Maintenance
The transfer switch is designed to be maintenance free under
normal usage. However, inspection and maintenance checks
should be made on a regular basis. Maintenance will consist
mainly of keeping the transfer switch clean.
Visual inspections should be done at least once a month.
Access to transfer switch must not be obstructed. Keep
3 feet (92 cm) clearance around transfer switch. Check for
an accumulation of dirt, moisture and/or corrosion on and
around the enclosure, loose parts/hardware, cracks and/or
discoloration to insulation, and damaged or discolored
components.

Descripción del Equipo
Esto conectador pertenecen a una nueva generación
destinada a transferir toda la carga de instalaciones
residenciales normales cuando se utilizan con los contactos
de supervisión previstos. La carga se conecta a la red
pública (normal) o a la alimentación doméstica de reserva
(generador). El conectador monitoriza las tensiones de la red
pública y del generador y conecta automáticamente la carga
a la fuente de alimentación apropiada.
Los componentes principales del conectador son un
interruptor bipolar de 2 posiciones de contacto, una tarjeta
de circuito impreso del módulo de control, terminales con
fusibles de detección de tensión de la red pública y cableado
de interconexión. La tarjeta de control también tiene dos
entradas para transformadores de corriente que detectan la
corriente del generador.
El conectador es accionado por un solenoide alimentado
desde las entradas de la red pública o del generador y tiene
interruptores de enclavamiento mecánicos y eléctricos,
adecuados para eliminar la posibilidad de conectar la red
pública a la salida del generador. Sus valores nominales son
suficientes para conectar toda potencia de la red pública a la
residencia. Para la función de transferencia hay una palanca
de cancelación manual.
La tarjeta de circuito impreso del módulo de control tiene
circuitos activos que detectan las tensiones de la red pública
y del generador. Genera una señal para el arranque del
generador, el conectador, la retransferencia cuando se
restablece la tensión en la red pública y los períodos de
enfriamiento del generador. La tarjeta de control contiene
también luces rojas y verdes que indican las fuentes de
alimentación disponibles y dos contactos accionados por
relé que proporcionan el control de supervisión de cargas
críticas externas.
