Safety Instructions
2-4 Simulix-Evolution Imaging – Service Manual 112.912ENG-04
2.3.2 Power Supply
For protection against main voltage interruptions, the Simulix viewing station contains an Un-interruptible
Power Supply (UPS) with a battery. The UPS performs a self-test automatically to check the battery. For
details, please refer to the UPS documentation.
The Flat Panel Detector and the interface box are permanently powered for stability reasons.
WARNING:
The Simulix viewing station contains an Un-interruptible Power Supply (UPS) with a battery. This
means that an electrical voltage (115VAC / 220VAC) may be present internally, even when the system
is not connected to a mains-socket.
WARNING:
The flat panel detector and the interface box are permanently powered for stability reasons. When
switching off the Simulix, the flat panel detector and the interface box are still powered.
Note:
When the flat panel detector and interface box have been switched off and the power is switched on again,
no service action is needed.
Caution:
Switch off the Mains for the system and switch off the power to the flat panel detector before
removing or replacing fuses. Accidentally contacting the electrical circuits inside the system could
result in serious injury.
Always use the correct size and type of fuse when replacing blown fuses.
2.4 Fire Safety
WARNING:
Do not use the system in oxygen-enriched atmospheres (more than 21% of oxygen) and/or in
atmospheres containing explosives or flammable gases.
2.5 Fluid Safety
If fluid is spilt over system components, then inspect and check the proper functioning of the system.
Caution:
The system is not protected against the ingress of fluids. The classification is IPX 0.
2.6 Radiation Safety
WARNING:
Always take X-ray radiation safety precautions.
See also related documents [6] and [7] (see Section 1.2).
X-ray radiation is only possible when the operator activates the foot-switch or manually activates the
exposure buttons. The software on the Oncentra Simulation station cannot switch on the X-ray radiation by
itself.
The Oncentra Simulation software can also inhibit radiation. When Oncentra Simulation detects a failure (for
example when the communication with the simulator is lost), Oncentra Simulation will inhibit radiation.

Safety Instructions
112.912ENG-04 Simulix-Evolution Imaging –Service Manual 2-5
The foot-switch is used to make fluoroscopy images. The images are visible on the Oncentra Simulation
station. After releasing the foot-switch the X-ray radiation is switched off. On the Oncentra Simulation station
the Last Image Hold (LIH) stays visible.
The Oncentra Simulation station shows the state of the image: Live or LIH.
In case of malfunction of the Oncentra Simulation station, it is not possible to save images on the Oncentra
Simulation station.
The operator can make an X-ray exposure of the patient on the auxiliary film cassette. If the auxiliary film
cassette is not placed in a correct manner or not present, then the X-ray radiation will not switch on when the
operator activates the exposure button. The simulator shows a warning message on the data monitor. When
desired the operator can now overrule the warning message and can make an exposure. See also related
document [1] (see Section 1.2).
2.7 X-Ray Exposure Interlocks
For the Simulix the following applies: A system of interlock switches and monitoring devices detects
abnormalities in the system (e.g. open covers, open doors, shutters too wide which would result in X-ray
outside the detector) and will prevent the operator from making an exposure until the system is brought into a
safe state.
WARNING:
Never bring body parts in the beam of an X-ray system.
2.8 Electromagnetic Safety
A diagram of the system interconnection with a list of cables is shown in Chapter 4, drawing 112.912-2xx.
WARNING:
The use of accessories and cables other than specified, with the exception of cables sold by
Nucletron as replacement parts for internal components, may result in increased electromagnetic
emissions or decreased electromagnetic immunity of the Simulix-Evolution system.
WARNING:
If the Simulix-Evolution system is used adjacent to other equipment, the Simulix-Evolution system
should be observed to verify normal operation in the configuration in which it will be used.
