24.2.1 Parts operated when the Power Switch and Auxiliary Power Button are
turned ON
• When the Auxiliary Power Button is turned ON, the Control Board detects it and sends a
control signal to the DC Power Supply.
• The DC Power Supply then supplies 3.3V DC, 5V DC, 15V DC, and 24V DC to all PWBs
and options. It also turns ON the relays in the PWBs, supplying AC power to each of the
heater lamps.
