Table 2-1. Exposure Signals Between PXCM and Generator
Signal Direction Description
PREP_DR_DET_ Generator to PXCM The Generator has started the preparations to perform an
exposure.
Activation:
The Generator activates the signal when the exposure
preparations have started.
Deactivation:
The Generator deactivates the signal when:
•
The exposure buttons are released.
•
A correctly terminated exposure has been proceeded.
PREP_DR_DET_ Generator to PXCM
Deactivation:
The Generator deactivates the signal when:
•
An error interrupts the exposure.
For timing requirements, see t_prep_end_dly.
GEN_RDY_FOR_DR_EXP_ Generator to PXCM The Generator is ready to expose.
Activation:
When the anode speed is reached, the signal is activated.
Deactivation:
The Generator deactivates the signal when:
•
The exposure buttons are released.
•
A correctly terminated exposure has been proceeded.
GEN_RDY_FOR_DR_EXP_ Generator to PXCM
Deactivation:
The Generator deactivates the signal when:
•
An error interrupts the exposure.
For timing requirements, see
t_gen_rdy_disable_to_ray_off.
Note: For an AEC pre-exposure, the signal will stay active
in the time interval between the AEC pre-exposure and the
AEC main exposure.
DR_DET_RDY_FOR_EXP_ PXCM to Generator The Detector is ready for an exposure.
Activation:
When the Detector is ready to receive X-rays, the signal is
activated.
DR_DET_RDY_FOR_EXP_ PXCM to Generator Deactivation:
When the Detector exposure window ends, the signal is
deactivated.
