Troubleshooting AC-Turn-on Circuits

Relay A1K1 closes at 2.5 seconds and DROPOUT goes high at 2.9 seconds after 20V (5V UNREG) reaches about 13Vdc. DROPOUT high enables the PWM if OVERVOLTAGE, and OVERTEMPERATURE are also high.

Circuits Included. AC-Surge-&-Dropout Detector, Bias Voltage Detector, Delay Circuits, and Relay Driver--all on A2 control board.

Setup. The Main Troubleshooting Setup, page 33. Apply the ac mains voltage to the isolation transformer, and set the external supply to 0Vdc.
