(2) Monopanel Switch Keypad (KP). Used to input units of light to be used during exposure. Contains
digits 0-9, a "C" key, used to cancel any exposure in progress or to cancel any information entered, prior to pressing the
"T" key. The "T" key is used to activate the exposure. The keypad is wired into the control circuit board.
(3) Digital Display (DO). Used to display the units of light entered via the key pad. During exposure, the
digital display will count down. At the end of the exposure, the display will return to the units of light that were originally
entered. The digital display is wired into the control circuit board.
(4) Integrator Circuit Board (ICB). Used to control the exposure time based on the units of light entered
and the intensity of the lamp based on input from photodetector assembly (PE1). It is mounted directly onto the control
circuit board.
(5) Control Circuit Board (CCB). Receives inputs from other circuits. Contains an electronic relay which is
used to apply power to relay K2, via the overtemperature switches (THS1 and THS2) and glass frame proximity switch
(PX2).
e. Exposure Indicator Lamp (L2). Power is received through proximity switch PX3. PX3 is located next to strike
transformer #1 (ST-1) and is activated whenever ST-1 is energized.
