Door Interlock Switch Connection
To wire a door interlock circuit, remove jumper and connect door interlock
wires (supplied by installer) to terminal block TB6 pins 1 and 2 on Interface
Board A9 [(P/N AY40-023T/or AY40-061T on internal high-speed starter sys-
tems) or (AY40-034T/or AY40-062T on internal high-speed starter systems)].
See Figures 2-15 or 2-16 for terminal board TB6 location. When the door is
closed, the circuit will be continuous (contacts closed).
"In Use" Light Switch Connection
To wire an "X-ray On" or "In-Use light", connect wires from light circuit (sup-
plied by installer) to terminal board TB5 pins 1 and 2 on Interface Board A9
[(P/N AY40-023T/or AY40-061T on internal high-speed starter systems) or
(AY40-034T/or AY40-062T on internal high-speed starter systems)] (On
AY40-062T boards, pin 3 is not used). See Figures 2-15 or 2-16 for terminal
block TB5 location. When the X-ray generator is in either PREP or EXPOSE
states, the circuit will be continuous (contacts closed).
