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 opera-
tion", 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° po-
sition. Switches S64/65 for the large range must be activated. During "litho opera-
tion", switches S76/77 for the limited range must be activated.
NOTE
SI Lines and cables
•
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.

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.
