The duration of the exposure blockage (cool-off period)
depends on the kV/mA step set and the actually triggered
radiation time. Depending on the tube load, pause times up
to 200s are set automatically.
Example: For P1 program with exposure data 74kV/10mA
and a radiation time of 11.3s a pause of 200s results.
