Safety Issues

Equipment to be Operated and Serviced by Qualified Personnel Only

X-ray equipment produces ionizing radiation that may be harmful if not properlyregulated. It is therefore recommended that the equipment be operated by trained and

qualified personnel only, in accordance with all applicable local and federal regulations.

Only trained and qualified technicians are authorized to service this equipment. Power

supply lines must comply with safety legislation and have ground terminals for protectiveearth connection. Always switch the equipment off and, if possible, disconnect it from

main power supply before cleaning or disinfecting the system.

Lifting and Transporting Column Assembly Requires Two Persons

The entire Column assembly weighs over 320 lbs (145 kg) and requires at least 2 persons

to lift and transport it.

Ensure Wall Can Support CDRPanX Wall-Mounted Installations

Before attaching the Holder, be sure that the wall can support the CDRPanX system

safely. Improper installation of the Holder or instability of the wall structure can damagethe system and / or injure the operator and the patient.

Avoid Operating Equipment in the Presence of Interfering RF Devices andEquipment

We recommend that you do not use the equipment in the presence of external

electromagnetic fields, even if compliant with specifications for electromagneticcompatibility. Noise, generated by cellular phones, might interfere with the electronic

circuits of the system.

Exercise Caution Near and Around Moving Parts

The Vertical Carriage and Rotation unit move during patient setup and panoramic

exposure procedures. Operators must take appropriate precautions for themselves and

their patients to prevent accidental injury during equipment operation.

Apply Recommended Procedures for Cleaning the Equipment

Safe and proper operation of the equipment requires that a regular schedule of preventive

maintenance be followed. In addition, the use of sterile sheaths and appropriatedisinfecting procedures must be observed to minimize patient exposure to cross-

contamination from bacterial or other infection. Use new sheaths with each new patient.Dispose of sheaths properly after use.

Do Not Connect Items that are Not Part of the System

Only items specified for use with the equipment are to be connected to the system. The

equipment should not be used adjacent to other equipment that is not part of the system.


8/67

vi B1051408 Rev. A CDRPanX Installati on

If, however, use with adjacent equipment is necessary, normal operation should be

observed and verified in that configuration.

When No Longer Usable, Dispose of System Components Properly

The CDRPanX system is made of a variety of materials, including iron, aluminum, lead,

copper, plastics, electronic components, and dielectric oil in the Tube head. Once thesystem is removed permanently from service, such components cannot be abandoned in

the environment. They must be disposed of in accordance with applicable local

regulations.

Protecting CDRPanX from RF Interference

Although the CDRPanX equipment is designed to provide a reasonable degree of

protection from electromagnetic interference, according to IEC International regulations,it must be installed at an adequate distance from electricity transformer rooms, static

continuity units, two-way amateur radios and cellular phones. To ensure proper

operation, the latter can be used only at a minimum distance of 6 feet (1.8m) from any

part of the equipment.

Any instrumentation or equipment for professional use located near CDRPanX must

conform to Electromagnetic Compatibility regulations. Non-conforming equipment, with

known poor immunity to electromagnetic fields, may not operate properly unless they are

installed at a distance of at least 10 feet (3m) and supplied by a dedicated electric line.

Preventive Maintenance

There are no customer-serviceable components in the CDRPanX system. However,before operating the system, customers shall check it for any signs of physical damage or

defect. If detected, contact your local distributor of Schick Technologies products for

further instructions.

Ensure Proper System and PC Workstation Installation and Operation

CDRPanX has been determined to be in accordance with international safety standardsand is deemed suitable for use within the patient area, which extends from the patient for

a distance of 5 feet (1.5m). To comply with these standards, do not operate non-medical

equipment (such as a PC workstation) inside the patient area. Outside the patient area, the

presence of approved non-medical grade equipment and Listed / Approved / certifiedInformation technology Equipment (ITE) computer equipment is acceptable.

The PC workstation that connects to the CDRPanX via compatible USB cable is an

integral part of a Medical Electrical System. The PC must be a CE-approved computer

system conforming with the Low Voltage [73/23/EC] and EMC Directive [89/336/ERC].Also, to help ensure optimal performance, ensure that all software programs residing on

the workstation are virus-free and have been adequately tested so they will not impact

imaging applications after installation.

Please refer to documentation provided by the PC manufacturer for important

information about its safe operation and usage.

is to be secured to the floor with the appropriate bolts.

2.2.2. Electrical

Only trained and qualified technicians are authorized to service CDRPanX equipment.

Power supply lines must comply with safety legislation and have ground terminals for

protective earth connection. For proper installation, the mains power cable of theCDRPanX unit must be permanently connected to the wall in such a way that its removal

can only be possible with the use of a tool.


14/67


Make sure that the available connection to the mains line is intercepted by a safety switch

to disconnect the equipment from the mains when needed. The connection to the mains

line has to be made on the wall on the back of the column at about 39 in (100 cm) fromthe floor. If the Exposure switch will be installed remotely, a 4-wire cable kit for remote

mounting is available.

Attach the following lines from the CDRPanX unit to the mains power lines, noting thecolor and description of the connecting cables:

Line (or live): Black wire labeled #1 on sleeve (verify that this is the fused line)

Neutral: Black wire labeled #2 on sleeve

Ground (also called protective earth): Yellow/ green wire

When routing the CDRPanX power cable, make sure it can move freely with the VerticalCarriage at minimum and maximum heights.

Visually inspect the system to make sure that all covers are in place and secured beforeturning the system on.

2.2.3. Data Communication

iPan HS interface, make sure it can accommodate the specified cable length.

2.2.4. Radiation Protection

The CDRPanX system is equipped with lead barriers to mitigate the incidence of residual

radiation. Additional shielding to the walls might nevertheless be required according to

local regulations.


15/67


3. Installation

When planning the installation, a width of 53 inches (203 cm) and a height of 92 inches

(234 cm) is needed, at a minimum, to accommodate the system (Figure 2). To measure

mid-plane from the center of the Column, a distance of 23 inches (58 cm) is required,although this would be minimal clearance.

The distance from the support wall to the system is 7" (18 cm) with the standard wall

bracket installed. The wall bracket should be mounted approximately 83" (211 cm) from

the floor, although this distance may vary due to floor variations or carpeting. We

recommend test-fitting the Column and wall bracket against the support wall prior toinstallation. If there is an adapter bracket or header external to the wall, this must also be

taken into account.

Figure 2. Distance Considerations for Wall-Mounted Installations

WARNING: Before attaching the Wall Bracket, be sure that the wall can support theCDRPanX system safely. Improper installation of the Bracket or instability of the wallstructure can damage the system and / or injure the operator and the patient.

For metal-stud sheetrock walls, cabinet hanging screws, similar to #8 fine-threaded self-

tapping zinc sheet metal screws, are appropriate. Use a minimum of six screws to install a

wood header and then fasten lag bolts from the CDRPanX unit into the wall holder.

Use the proper bolts when attaching the Wall bracket to the wall. Each bolt tolerates aload of 980 N or about 220 lbs (100 kg) including a safety factor. If the wall cannot

support the indicated load, reinforcing plates or headers should be evaluated as a solution.The recommended bolts are listed in the following table.

11. Functional Description

11.1. System Descr ipt ion

Main power lines are connected to the CDRPanX system via a terminal board in the

Power Inlet on the lower left of the Vertical Carriage. The Power Inlet also contains themain power fuse and switch. From the inlet, power is routed to the Main Power Supply

unit, located on top of the Vertical Carriage.

Cables conduct power from the Main Power Supply unit to the Power Switching unit

located above the tube-head and connected to it inside the Rotation unit. The PowerSwitching unit is connected to the Regulation board by flat cable. The Regulation board

can be found above the Control Panel.

The System Control unit drives the Control Panel, the power regulator, and the motor for

the Rotation unit. Position sensors provide position information to the System Controlunit. They are used to sense initial and end positions of rotation and to distinguish the

first and second halves of Rotation unit motion and movement during exposure. The

sensors are made of two parts: infrared LED emitter and phototransistor receiver.

11.2. Main Power Supply Unit

Main power lines are connected through the main power switch, fuse, and EMI filter to

the Main Power Supply board. Power is applied to the low voltage circuitry via a relay tothe high voltage circuitry. When power is applied, regulated voltages of +15Vdc, +24Vdc

and un-regulated +38Vdc are generated.

During exposure, DC high voltage is connected to the Power Switching unit, which

supplies power to the X-ray tube head. This circuit also activates the yellow light on theExposure hand-switch.

Fuse FU 301 (input power from main power) protects the system and is located near the

Power Inlet on the lower left side of the Vertical Carriage.

Fuse FU 303 protects the low voltage transformer circuit. Fuses FU 304 and FU 305protect the DC high voltage circuit to the Power Switching unit. These fuses are located

on the Main Power Supply at the top of the Vertical Carriage.

11.3. Power Switching Unit

During tube filament heating and X-ray exposure, high voltage (DC) from the mainpower supply is provided to the Power Switching unit. 80 kHz pulses are supplied to the

filament regulator driver. The output voltage of the regulator depends on the duty cycleof the driving pulses.

Feedback from the regulator output is sent to the Regulation board.

Pulses at 40 KHz are supplied to the filament inverter driver. Output from the invertergoes to the filament transformer in the tube-head. The inverter current is sensed by a

dedicated resistor shunt and the signal is monitored by the Regulation board.

During tube filament heating, 20 kHz pulses are supplied to the High Voltage (HV)

inverter driver. During X-ray exposure, the pulses are also supplied to the HV regulatordriver.

The output voltage of the regulator depends on the duty cycle of the driving pulses.

Feedback from the regulator output is provided via opto-coupler to the Regulation board.

Output of the inverter is connected to the HV transformer in the tube head.Inverter current is sensed by a current transformer and monitored by the Regulation

board.

Figure 26. Power Switching Unit


53/67


11.4. X-ray Tube Head

High voltage is generated by a transformer and cascade multiplier. The feedback signalsof both the anode voltage and the anode current are monitored by the Regulation board.

The X-ray tube filament is supplied by a dedicated transformer. A tube head temperaturesensor is monitored by the System Control unit, which prevents X-ray emission if the

temperature is high enough to exceed threshold limits.

Figure 27. X-ray Tube Head


54/67


11.5. Regulation Board

The Regulation board controls the technique factors (kV and mA) by checking thefeedback signals coming from the tube-head and comparing them with the desired

settings from the control unit. This control signal is passed to the voltage regulators onthe power switching unit.

Anode voltage (kV) level is controlled by setting the input voltage to the HV transformer.

Anode current (mA) is adjusted by controlling the filament supply.

2. Change the Voltage Jumper from 230V to 115V.

3. Replace fuse FU 301 on the lower left side of the Vertical Carriage with thesupplied 16 amp fuse: (T 16.0A 250V 6.3x32mm slow blow). This will alsorequire changing the fuse holder insert to the included 6.3x20mm rather than the

5x20mm insert.

4. Replace fuse FU 303 on the Main Power Supply board at the top of the VerticalCarriage with the supplied 3.15 amp fuse: (T 3.15A 250V 5x20mm slow blow).

5. Verify that fuses FU 304 and FU 305, located on the Main Power Supply board,are 6.3 amp (F 6.3A 250V 5x20mm).

6. Verify supply voltage (at outlet or electric box) is 115V.

7. Apply replacement system label over existing label and mark 115V selectionusing permanent black ink pen.

8. Connect the CDRPanX to the 115V main supply.

9. Turn on the Main Power Switch on and perform a system operational check.
