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. Information on handle
use can be obtained by calling Technical Service at 800-743-4115.
Operation
To select automatic transfer operation, do the following:
1. In transfer switch, set utility disconnect circuit breaker
to ON position.
2. In transfer switch, set generator disconnect circuit breaker to
ON position.
3. Install 15 Amp fuse in generator’s control panel.
4. Set generator’s circuit breaker to ON position.
5. Set generator’s system switch to AUTO position.
The system will now be in automatic operation mode.
When the generator is providing power to the transfer switch, the
transfer switch control board is constantly monitoring generator
power and communicating with the Symphony II system
control board.
The Symphony II system will control up to 8 priorities, with priority
9 and 10 as lockouts. When total generator load meets a preset
value, the Symphony II system control board will start shedding
loads, starting with the lowest priority (highest number) load. The
Symphony II system will add or shed managed loads based on the
generator output capacity and priority settings.
The Symphony II system waits 10 seconds between adding
or shedding each load to permit the system to stabilize. If too
much load demand is seen, the Symphony II system will shed all
managed loads quickly to prevent the generator from overloading.
Once the load demand has stabilized, the Symphony II system will
re-load the generator after a 5 minute delay, as describedabove.
There is a minimum five minute delay between the time utility
power is lost and priority 1 loads are energized by the
Symphony II system.
Be aware that managed heating element energy loads (such as
electric range burners, oven, or space heaters) that were ON
when utility power was lost, will be ON when the generator begins
supplying power. It is advised that the owner check all such
managed devices to ensure they are turned OFF before generator
power appears.
Managed devices like clothes dryers that require pressing a START
button will not resume operation unless the START button is
pressed after generator power begins.
Enclosure Door
To open the transfer switch door, remove the two
exterior thumb screws (A) and carefully lift off door.
To close and secure the door, push door closed
against enclosure making sure that the tab on the
enclosure fits into the slot on the door. While in this
position, the door can rest on the tab (B) at the bottom
of the enclosure. Reinstall both thumb screws to finger
tight. Enclosure door MUST be closed and secured at
all times except when system is being serviced.
Symphony™ II Power Monitor (Optional)
For your convenience, a Symphony II Power Monitor is available,
which provides a visual “on/off” status of each managed appliance/
load. A series of LED lights are ON when an appliance has
generator power and OFF when the appliance is in a shed mode or
does not have power. When on generator power, the consumer can
see which appliances are beingmanaged.
A decal is provided that can be labeled with the managed
appliances/loads and placed next to each priorityLED.
The monitor is plugged into any convenient standard outlet within
the home and constantly receives system status via the power
line communication technology utilized by the Symphony II Power
Management System during generator power.
