Overload protection

Prolonged continuous radiation at maximum tube load is permissible in fluoros-
copy mode. However, this can cause the X-ray tube assembly to heat up. For this
reason, the X-ray tube assembly has a thermal monitor. If necessary, power is
reduced in all operating modes, in SUB/Roadmap with the next new scene/mask.
If the temperature rises to ≥ 50 °C,
the temperature indicator on the control panel of the C-arm system lights up.
the selected characteristic curve is switched to S1 at the end of radiation in
fluoro and pulsed fluoro.
If the temperature rises to ≥ 60 °C,
the selected characteristic curve is switched to S1 during radiation in fluoro
and pulsed fluoro.
If the temperature rises to ≥ 70 °C,
the temperature indicator on the control console of the C-arm system flashes.
radiation is aborted and cannot be released again.
If the temperature falls below 50 °C,
the previously deselected curve is automatically reselected.
