3.1 Electrical Safety
SI Emergency-off switch function
• Operate the emergency-off switch in the room.
- The system must switch off.
- The system cannot be turned on until the emergency-off switch is released and the
voltage supply is switched back on.
SI Function of the fault current circuit breaker
• Check the mechanical functioning of the fault current circuit breaker by operating the
built-in test button.
• Check electrical functioning according to ARTD-002.731.17.
SI Safety circuit switch function
• Check the safety circuit for the O-W-X-Y motor movements in table G1 using the
J1042-7 circuit diagram.
• After connecting and logging on to the service PC, the Adjustment/Calibration service
software program can be used to move the motor drives to the safety switches without
software monitoring.
(See Operating the Service Software)
• Use the tableside control panel to move the drives into the safety circuit while monitor-
ing the appropriate limit switch.
NOTE
- When checking the X-drive using the "urology insert", move the O-drive to the +10°
position to avoid risk of collision with the tube assembly housing. During "litho operation", move the shock wave head to the coupling position and move the X-drive to
S78 in a limited range.
- In the case of a Y-drive check using the urology insert, move the O-drive to the 0° position. Switches S64/65 for the large range must be activated. During "litho operation", switches S76/77 for the limited range must be activated.
NOTE
SI Lines and cables
Do not move to the mechanical end positions!
If the safety switches are actuated, you can move the drives out of
the safety zone by activating service button S59 on N11 or service
button S58 on D32 in the unit.
• Check the line and cable insulation for damage or kinks to the extent possible.
• Check charging line K26 for a secure connection and a good ground connection at the
charger and the shock wave generator.
SI HV cable shielding
DIN VDE 0750 Part 21 (IEC 601-2-7) Paragraph 16
The high voltage cables that can be touched and that conduct the tube current must be
provided with a flexible, conductible shielding that has a maximum resistance of 1 ohm/m.

14 Safety inspections
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
Wait until the red LEDs on D110 are no longer lit (approx. 1 min.).
• 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!

SI Time - radiation indicator
Check functioning of the radiation indicator and functioning of the different FL release buttons 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.
• 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.
• 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.
• 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.

• Reset the fluoroscopy timer to zero.
(See Start-up Instructions, paragraph 4-6)
SI Function switch of the generator
• Check functioning of the service switch on board D100 in the generator. When the ser-
vice switch is off, radiation release must be blocked (no activation of the inverter!)
• Check functioning of switch S2 on board D160. When S2 is in the OFF position, the line
contactor of the generator may not switch on. (Multiline, not operating)
NOTE
SI Protective conductor check
When the generator is switched off, there is still line voltage
present at the T1 transformer and the D160 switch-on circuit.
(See LX circuit diagram X2169-11 or SX circuit diagram X2206-11)
After switching off the generator, approx. 600 V DC is still available
for the inverter! This is indicated by LEDs V135 and V136 on board
D110.
(See LX circuit diagram X2169-16 or SX circuit diagram X2206-16)
The voltage dissipates within approx. 1.5 minutes to 0 V; the LEDs
go off at approx. 30 V.
• Test the protective conductor with the protective conductor tester according to
ARTD-002.731.17.
The protective conductor connection in the generator is the central protective
conductor.
(The protective conductor check must be performed again as a final step when the
system is closed!)

• Cracks on the back or at the tooth base; replace toothed belts if necessary.
• Ensure that the clamping pieces of the toothed belts are secure.
SI X-ray tube assembly
SI Collimator
SI Image intensifier with camera head
• Ensure that the screw connections of the X-ray tube assembly on the C-arm are secure.
• Ensure that the collimator is securely attached to the X-ray tube assembly.
• To check the mounting of the collimator, remove the large rectangular cover of the radi-
ation protection housing and then reinstall it. The collimator may not rotate at the housing flange.
• To check the image intensifier mounting, remove its rubber cover and the protective
cover of the camera.
• Check the mounting of the image intensifier.
• Check the mounting of the camera at the image intensifier.
• Reinstall covers.

• Check the maneuverability ranges of the unit, the O-W -X-Y-Z-drive during lithotripsy
and urology operation. Maintain the safety distances in the end positions of the unit
movements.
SI Urology insert
• Insert the urology insert and ensure that it is secure.
• Ensure that S22 is properly switched.
• Adjust switch S22 if necessary.
• If needed, adjust both guide pieces of the urology insert. For this purpose, insert the
