The shielding must be connected to both the metal housing of the X-ray generator and the
X-ray tube assembly.
Conduct a check using measurements as follows:
•
Switch off the system contactor.
NOTE
•
Disconnect the high voltage cable from the socket at the HV generator and measure the
shielding mesh against protective ground. Move the cable, particularly at bends and
loops.
- High voltage cables with a shielding mesh resistance
exceeding the maximum of 1 ohm/m are to be replaced.
- Reinsert the cables
Only use transformer oil for inserting the high voltage plugs at the HV generator. Do not
use silicone washers!
Set of spare parts:
Installation material "washers"
1 l transformer oil as needed
SI Time - radiation indicator
Check functioning of the radiation indicator and functioning of the different FL release but-
tons while the FL time display and/or time-out for fluoroscopy are running.
•
Reset the fluoroscopy timer to zero.
•
Move the filter (approx. 0.3 mm Cu) into the fluoro unit beam projection.
•
X
Switch fluoroscopy ON at the fluoro unit.
The timer counts up.
Observe radiation protection regulations!
•
Check the radiation indicator at the control monitor.
During fluoroscopy, a symbol for radiation release appears on the left of the control
monitor in the status field.
•
X
Check functioning of the FL release buttons on the connection panel of the control con-
sole and the footswitch at the console and/or unit.
•
X
During fluoroscopy and exposure, check functioning of the radiation indicator lamp on
monitor trolley N72 (optional) or the local radiation indicators.
After a total of 4.5 minutes, a signal generator must sound.
•
Switch off the signal generator. Do not reset the FL timer.
After 9.5 minutes, the signal generator in the control console must sound.
•
Switch off the signal generator. Do not reset the FL timer.
Fluoro must switch off within 10 minutes.
•
Switch fluoroscopy OFF at the fluoro unit.
