1.4 How the OVATION™ Series Automatic Transfer Switch Works:
1)When the utility power fails or drops below 190 volts or 54 Hz or exceeds 280 volts or 66 Hz, the OVATION™ Automatic Transfer Switch will begin the generator starting sequence after a 5-second delay.
2)Once the generator is started, the system is programmed to allow the generator to warm up and wait for possible successful utility power grid re-strike (approx. 15 seconds) before the load is transferred to generator power. At the time of load transfer to generator power, all appliances connected to PowerPause™ Load Management modules are disconnected (“locked out”) for 5 minutes to avoid overloading the generator(e.g. allows time for head pressure bleed-off in AC Compressors). NOTE: For best results, electronic equipment such as computers, clocks, security systems and phone systems should be connected to an Uninterruptible Power System (UPS) to ensure no data is lost until transfer of power occurs.
