Signal Descriptions
l
SHOT1 RDY1/RDY1 (Input)
The signal is generated when only the first stage of the shot switch on the X-ray high
voltage generator is pressed. (Prep signal)
l
SHOT1 RDY2/RDY2 (Input)
The signal is generated when the first and second stages of the shot switch on the
X-ray high voltage generator are pressed. (RAD signal)
l
BKY1 RDY1 A/B (Output)
The signal prepares for the bucky operation.
A relay type is normally open (NO).
l
BKY1 RDY2 A/B (Output)
The signal operates the bucky upon completion of the preparation for the SE
exposure.
A relay type is normally open (NO).

exposures corresponding to the first stage of the switch when the shot switch (first stage)
is turned ON.
B: Preparation starts for SE exposures corresponding to the second stage of the switch
when the shot switch (second stage) is turned ON.
C: The signal for operating the bucky is output upon completion of the preparation for the SE
(FPD) exposure.
D: An exposure request signal is output after a predetermined time elapses since the bucky
operation starts, and X-ray exposure starts.
E: X-ray exposure ends.
F: Charge accumulation of the SE (FPD) ends.
