1 INTRODUCTION
The XR3D-6 is a 3D perspective X-ray imaging scanner designed to provide enhanced and
reliable security screening at critical points-of-entry, and across multiple customer applications.
Based on a single X-ray source, the XR3D-6 scanner provides automatic alerts to operators of
the presence of a range of possible threats, including: explosives, weapons, sharp objects,
narcotics and contraband.
This manual applies to the VOTI XR3D-6 and contains troubleshooting and maintenance
information for VOTI-trained Level 1 and Level 2 technicians.
Level 1 is expected to attempt fix-on-first-contact by way of simple troubleshooting
guidelines or by calling upon the Level 2 Help Desk.
Level 2 requires a VOTI-trained Technician responsible, but is not limited to, onsite
installations or replacements of various hardware components, diagnostic testing, and in
certain cases, Line Replaceable Unit (LRU) repair.
Level 3 requires VOTI personnel responsible for handling the most difficult or advanced
problems denoting expert level troubleshooting and analysis.
The maintenance manual includes instructions to perform software updates, troubleshooting,
and repair procedures for the following hardware components:
oPower sources and 12 VDC circuits
oConveyor assembly
oComputer related issues
oX-ray scan image generation
oImage display
A wiring overview of the XR3D-6 configuration is provided to facilitate verification of power inputs
and outputs.
1.1 Hardware Overview

3. Operator Key Switch, Keypad, and USB slot
4. Warning Lights
5. Emergency Stop buttons
6. Bi-directional conveyor belt assembly
7. Base on casters and adjustable legs –with locked access panels with interlock switches.
The base houses the UPS, the Power Distribution Unit, and the X-ray source
8. The right base panel contains 110-120V 60Hz (or 210-240V 50Hz) Power connector, 10A (or
5A) Circuit Breaker, Computer On/Off toggle switch, and the optional Floor mat connector
1.2 Software Overview
BioSans© is the main Operator interface for all system communications, generation of 3D
perspective images, and X-ray scanning. Its functionalities focus on the clarity and quality of the
3D perspective images, high level of threat detection and ease of use for the operator. BioSans©
technology includes the following:
Automatic detection system alerts the operator of the presence of potential threats, for
example, prohibited organic material, explosives, high density, or sharp objects. The list of
materials can be customized.
oOrganic –anything with a carbon base –for example, clothing, food, water, paper
oInorganic –anything metallic –for example, cell phone, knife, firearm
oMixed Organic/Inorganic recognition
Image Enhancement uses zoom, pan, flip, and contrast to enhance the scanned image.
Continuous Screening customizable modes, Full, Simple, or Off
Manual Search Required (MSR) to tag items and save the archive files to a specific folder.
The scanned item is directed to an optional search area.
Language Selection provides multilingual operator interface, for example, English, French,
Spanish, Arabic
Remote Monitoring Station (Optional)
Material Classification (Optional) customizable detection material groups
Risk Assessment Module (Optional) defines 5 different levels of security which modify
system settings to provide better image quality and more accurate detection
TIP Management (Optional) provides continuous Operator training and evaluation
Advanced System Settings - BioSans© maintenance applications which are used by a
Technician and can be triggered by an Administrator/Supervisor

1.3 Operation Workflow
The following flowchart describes how a Technician accesses the XR3D diagnostics software
using the key pad. This is described in Section 3.3 Control Box Access - Technician.
The keypad diagnostics can be used in addition to the DIOX application. The keypad tests
input/output communication with the hardware, whereas the DIOX tests input/output
communication through the computer.
The following flowchart describes how the XR3D is used by an Operator, as described in the
Operator Manual.

1.4 Safety Information
For a complete list of XR3D safety features, refer to Section 7, XR3D-6 Safety Features.
Training must be provided by a qualified VOTI-certified subject matter expert (SME)
covering scanner operation, maintenance, basic radiation protection, and safety
procedures associated with the XR3D.
The XR3D is a machine that generates X-rays to inspect items for security purposes. This
machine has been designed and constructed to meet or exceed the requirements of the
Radiation Emitting Devices Act (Canada), and the applicable Regulation (Schedule II, Part IV –
Baggage Inspection X-ray Devices) and in accordance with the International Commission on
Radiological Protection (ICRP) methodology, including the As Low As Reasonably Achievable
(ALARA) Principle.

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 than 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
