Note 4 : In test circuit; if any of switches SW3, Sw4 or SW5 opens , then the alarm signal will be activated (+5V). Note 3: In test circuit; 5pF capacitor across the load re sistor is add to simulate LCD back-light stray capacitor. Note 2 : Open circuit on all lamps for more than 3 seconds, will shut the inverter down.
