Overload Protection; Radiation Protection; Mechanical Saftey - Siemens MULTIMOBIL 10 Installation Instructions Manual

1.2

Overload Protection :

The unit is designed to work between 99 V to 121 V on 110 V or 180 V to 265 V on
230 V line ac single phase supply with a 15A socket. For safety purposes 10A HRC
fuses are provided which will blow when a current exceeding 10A sustains for its
response time.
Ensure that the mains socket is properly earthed.
In case of fault if the kV tries to build beyond the safe limit of X-ray tube the protection
circuit blocks the HT.
In case of fault, if the Filament current tries to increase beyond the safe limit the
protection circuit blocks filament boosting.
1.3

Radiation Protection :

Do not put any part of your body in the direct line of radiation.
Collimate the X-ray beam.
Keep maximum possible distance from the object being radiographed. For this
make the best use of 5m of recoilable exposure release switch.
Wear protective clothing.
Monitor radiation received using the personal TLD-badges or pen-dosimeter.
1.4

Mechanical Saftey :

Before releasing arm assembly from its locking position, ensure that the single tank
assembly along with covers, yoke and collimator is in the original position.
In case a difficulty is encountered in releasing the lock, any adjustments or alignments
must be done with complete single tank assembly in the locked position only.
Do not attempt to release the lock by any other means.
The arm will not be counter-balanced if any of the single tank assembly parts like
cover are removed.
Any detection of physical damage of single tank assembly or breaking or loosening of
its parts (except handles) indicates possible danger of upward force the order of 25kg,
when the arm is released from its locked position. In such a situation, it is
recommended to suspend the installation and contact FACTORY for further
clarification.
