XT V 160 X-ray System XTM0011-F2 17
3 Warnings
There are hazardous aspects associated with the operation of this equipment. Under normal
use, no hazard is presented to the operator. The areas where a potential hazard may occur
are listed in the following sections.
3.1 General
The following warnings are identified as hazards:
• High voltages are associated with the production of X-rays. Whilst under normal
operating conditions these do not pose a problem, care should always be taken to ensure
that equipment is not exposed, damaged or operated in an unsuitable environment, for
example, wet or very damp conditions.
• Both X-ray production and manipulator use are interlocked to the door closed switch.
The following warnings are identified as mandatory actions which must
be followed to prevent a hazard:
• Always observe all current safe working practices when working on electrical systems.
• Turn off the machine and remove/isolate all mains inputs before removing any inspection
covers.
• The X-ray system operates at hazardous voltages and so access to service areas is
restricted to suitably skilled technicians. The machine must be isolated from the mains
supply before removal of any covers.
The following warnings are identified as prohibited actions that must
not be performed:
• Do not remove any panels or covers from the machine whilst operating or powered up in
any way.
• Do not try to produce X-rays with any safety interlock overridden or with any radiation
panels removed.
• Do not apply power to the machine until all covers or panels have been fitted and
secured correctly.
• Never operate the system at full X-ray power without a sample between the X-ray source
and the imager.
• If the user interlock door switches become damaged, the operator must stop using the
system at once and report this damage to Nikon Metrology.
• Do not interfere with or try to override the door interlock switches as this may result in
exposure to mechanical or radiation hazards.
• Damage, however small, to the cabinet door glass (where fitted) must not be repaired, as
the glass is a special leaded type. If damaged, the system must not be used, and the
damage reported to Nikon Metrology.
• Ensure the required space set out in the installation drawing is left around the system. Do
not block or restrict any exterior vents.
