The transfer switch control board has active circuits sensing utility and generator voltages. It creates a signal for generator start-up, switch transfer and retransfer when utility is restored. The transfer switch control board provides status LED’s to indicate the power source available.

The Symphony™ II power management system control board contains a test button, a status LED and eight priority load LED’s. It creates and sends signals to optional remote modules, instructing them when to add (turn power on) or shed (turn power off) the managed load.

Delivery Inspection

After opening the carton, carefully inspect the transfer switch components for any damage that may have occurred during shipment.

If loss or damage is noted at time of delivery, have the person(s) making delivery note all damage on the freight bill and affix his signature under the consignor’s memo of loss or damage. If loss or damage is noted after delivery, contact the carrier for claim procedures. Missing or damaged parts are not warranted.

The Symphony II system power line carrier technology has been rigorously tested and has proven to be very robust. However, certain types of devices and appliances in the home generate ‘noise’ on the power line. Such devices may include non-residential fluorescent ballasts, dimmers, speed controls (lighting and fans), bathroom equipment, kitchen equipment, power tools, phone chargers, and power supplies. These types of devices have the greatest impact on power line communication when located close to a

remote module.
