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 800-732-2989.
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 three times each
year. Access to the transfer switch and optional remote modules
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.
Exercise the transfer switch and Symphony ® II system at least
once every three months as described in Testing the Automatic
Transfer Switch and in Testing the Symphony ® II Power
Management System unless a power outage occurs and the entire
home generator system has gone through an automatic sequence.
Allow generator to run for at least 10 minutes during exercise cycle.
Contact a licensed electrical professional to inspect and clean
the inside of the enclosure and other components of your home
generator system at least once a year.
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.
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.
