XR3D-6 Maintenance & Troubleshooting

The XR3D is designed to function so that, at any time X-rays are being produced, the average
exposure is less than than 0.5 milliroentgen per hour or less tha
n 5 μSv/h (Europe - 0.1
milliroentgen per hour or less than 1 µSv/h).
The machine is key-operated, with warning lights to clearly indicate when the power is on and
when X-rays are being produced. There is an optional floor mat upon which the operator stands
equipped with a control switch which stops the conveyor and terminates the production of X-rays
in the event that the operator steps off the mat.
Labels identifying the manufacturer, the model designation, the serial number, and the date and
place of manufacture are located on the left base panel of the machine and on the exterior
surface of the X-ray generator (normally only visible during servicing). These labels must not be
removed by the purchaser or user.
All XR3D’s carry a number of X-ray warning signs, one visible to the operator, and one at each
of the entrance and exit openings. These X-ray warning signs are required under the authority of
the Radiation Emitting Devices Act (REDA) (Schedule II, Part IV, Paragraph 2 (h)), and must not
be removed. If they deteriorate over time, or become damaged while in use, they must be
replaced. Replacement warning signs must comply with Paragraph 4 of the regulation. It is
important to note that although the machine produces X-rays and requires the above warning
signs, when this machine is properly installed and maintained, and operating as designed, the
operators are not required to wear personal dosimeters. When the XR3D is operated according
to design criteria they do not emit detectable radiation higher than the natural limit of permissible
exposure.
In addition to intelligent software that monitors system status, the XR3D ensures the following
safety features are in place before a scan can be conducted:
1. Access panels must be securely in place. This is verified by interlock switches in the access
panels.
2. The Operator Key switch must be turned to the ON position.
3. An Operator must be standing on a safety mat (optional).
4. An item must be detected by the photo sensors in the tunnel.
5. Indicator lights on the top of the XR3D turn Red.
6.
Caution symbols display on the operator’s monitor.
The XR3D is safe to operate and it is not necessary for operators to wear personal dosimeters or
special radiation protective clothing. However, the following general safety measures must be
followed when operating the XR3D:
Never reach inside the tunnel past the protective drapes while the system is in operation,
while the conveyor is moving, the X-ray lights are red or the X-ray indicator is showing on
the monitor.
All maintenance must be performed by a VOTI-qualified service technician.
1.4.1 Responsibility of the Owner
Owners of devices installed outside of Canada must comply with the applicable requirements of
their jurisdiction.
The XR3D complies with the requirements of the REDA (Schedule II, Part IV). The owner is
responsible for its safe operation and maintenance. In general, these requirements are
described in Safety Code 29, referenced in Canada Labour Code Part II. Safety Code 29 places
