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 described above.
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.
