1.1.6 Electromagnet
Electromagnetic
ic Compatibili
Compatibility
ty (EMC)
In accordance with the intended use, some models of this series of X-ray generators comply with the
European Council Directive concerning Medical Devices as per the table in this section. The CE marking
affixed to this product signifies this. One of the harmonized standards of this Directive defines the
permitted levels of electromagnetic emission from this equipment and its required immunity from the
electromagnetic emissions of other devices.
It is not possible, however, to exclude with absolute certainty the possibility that other high frequency
electronic equipment, which is fully compliant to the EMC regulations, will not adversely affect the
operation of this generator. If the other equipment has a comparatively high level of transmission power
and is in close proximity to the generator, these EMC concerns (the risk of interference) may be more
pronounced. It is therefore recommended that the operation of equipment of this type such as mobile
telephones, cordless microphones and other similar mobile radio equipment be restricted from the vicinity
of this X-ray generator.

740914-01


1.3.3 Generator Ground Requirements
POWER LINE:
• A suitable ground must be connected from the disconnect switch to the main generator ground,
located to the left of the main fuse block on the power input board. The ground wire is typically part of
the line cord, and the current capacity of the ground conductor must normally be equal to or greater
than that of the line conductors.
• If a neutral line is provided with the system, under no circumstances is it to be used for ground
purposes. The ground conductor must carry fault currents only.
X-RAY TUBE HOUSING:

• A copper ground cable, #10 AWG (6 mm ) or greater, is to be connected from the X-ray tube’s
housing to the H.T. tank ground stud (located at the top of the H.T. tank).
STATOR CABLE:
• Use of a shielded stator cable is recommended. The shield for the stator cable must be properly
grounded at the chassis ground studs as per chapter 2.
1.3.4 Locating and Mounting the Generator
The main generator cabinet is self standing and does not need to be supported. However, the installation
should meet the following requirements:

• The floor must be flat and level.
• The generator installation area must be clean and free of dirt or debris.
• If required, the generator may be anchored to the floor via the hold-down brackets (figure 1-1) or via
the holes located in the base of the cabinet (figure 1-2).
• Sufficient room must be provided to allow access to the rear and side panels for installation and
service. See figure 1-3 for recommended clearances.
• A cable conduit sh
should
ould be provided from the control console to the main cabinet to allow routing of
the control cable if required. Allow for a 2 inch conduit.
• The control console is normally freestanding on a desk or shelf. It may be anchored if necessary.

2.3.0 LIFTING THE GENERATOR
One of the following methods is recommended for lifting or moving the generator. Proper equipment or
sufficient help is necessary to lift the unit. Refer to figure 2-1 for identification of the panels referenced
below.
• Lifting straps may be used with a hoist to raise the generator. The straps should be placed under the
generator cabinet and along the four sides to properly support the cabinet.
• Remove the main access panel and the rear wiring access panel from the generator cabinet
Temporarily disconnect the ground wire(s) from the cover(s). The metal cross brace found at the front
of the cabinet (below the circuit board mounting panel) may be used, in conjunction with the lip at the
upper edge of the opening for the rear wiring access panel, as lifting points. Two people (one on each
side) will be required to lift the generator cabinet.
Be sure to properly reconnect the ground leads when the covers are reinstalled.

et
Place the generator cabinet in a location that will allow the following:
• Easy front and side access for service and sufficient clearance at the rear for room interface cables.
Refer to Chapter 1.
• Air circulation - a minimum height of 1 ½ in. (35 mm) is recommended to allow airflow underneath the
generator.
• Stable footing - the leveling feet at the bottom of the cabinet will be used to prevent movement during
normal operation.
• Close proximity to service disconnect boxes - cables should not be on the floor where they could be
stepped on.
After the generator has been placed in it’s final

fina l location, adjust the leveling feet such that the generator is
level and stable. As noted previously, the leveling feet must be unscrewed by a minimum of 1 ½ in. (35
mm) to allow for proper airflow underneath the generator.
2.4.2
2.4.2 Contro l Conso le
Position the control console in its intended location and ensure that it is stable. Refer to Chapter 1.
• If the console is located on a shelf, supply index pins or equivalent hardware to the base of the
console to prevent slipping.
• Ensure that the console is mounted at a height and angle to allow easy viewing of the displays.
• Leave sufficient slack in the cabling to the console to allow for future service and maintenance.
NOTE: DO NOT LOCATE

TOR
Unless specified otherwise, it is suggested that all cables be routed into the generator main cabinet
through the wiring access panel on the rear of the cabinet. The cables should be secured to the lip on the
access panel using tie wraps or equivalent fasteners.
All cables
cab les should be routed away from high vol
voltage
tage areas in the main cabin
cabinet,
et, and dressed and
secured neatly in place. Cables should be cut to the correct length if possible as excess cabling may
contribute to EMI/RFI problems. For those cables that cannot be cut to the correct length (HT cables and
console cables
are in effect for example), try to minimize the area inside any loops of excess cable, as these loops
an antenna.
EXCESS LENGTHS OF CABLING MUST NEVER BE BUNDLED UP AND STORED INSIDE THE
GENERATOR.

Follow the steps below to verify and configure the correct low speed starter boost voltage.
1. Confirm the required BOOST VOLTAGE for the selected tube type per table 1 in supplement
746026, which follows chapter 2. The requirement for the vast majority of tubes in table 1 is 240
V. For tubes that require 120 V boost, this is noted along with the run voltage, boost time, etc for
that tube.
• Refer to figure 2-6 (power supply auxiliary transformer). Locate this transformer under the
power input board; refer to chapter 1 for details.
• If there is only one connection on the 120V tap on the power supply auxiliary transformer, the
boost voltage is set to 240 VAC.
• If there are two connections on the 120V tap, the boost voltage is set to 120 VAC.
• Confirm the correct boost voltage at F1 on the low speed starter board with a suitable
voltmeter.
• Go to 2.6.3 if the boost voltage is properly set for the selected tube type and therefore does
NOT need to be changed.
2. If the boost voltage tap on the power supply auxiliary transformer needs to be changed from
240V to 120V, proceed as follows:
• Loosen the clamping screws for the 240V tap and for the 120V tap.
• Move the boost voltage lead from the 240V tap to the 120V tap. The boost voltage lead is the

• Locate this transformer under the power input board; refer to chapter 1 for details.
• Locate the run-voltage output on the transformer. This will be set to the 52V, 73V, or 94V tap,
and must match the required run-voltage for the selected tube in table 1.
• Go to 2.6.4 if the run-voltage setting is correct for the selected tube type, and therefore does
NOT need to be changed.
2. If the run-voltage setting on the power supply auxiliary transformer needs to be changed, proceed
as follows:
• Loosen the clamping screws for the current run-voltage tap, and for the required run-voltage
tap.
• Move the run-voltage output lead from the current tap position to the required tap position
(52V, 73V, or 94V). Ensure that the wire is positioned between the two metal clamps on the
transformer terminal block.

2.8.0 TUBE MA AUTO CALIBRA TION
It is recommended that the generator be tested at this point with only the rotor and high tension cables
connected. The generator should be able to complete an X-ray tube calibration and seasoning cycle
without other equipment connected to the generator (other than the basic interlocks as noted below). This
will allow for easier fault isolation as each section of the system is connected and tested.
Before being able to make X-ray exposures, the room door interlock must be closed and the
thermal switch must be closed.
closed.
Prior to beginning tube auto calibration (per the procedure in chapter 3), the tube(s) used in this
installation must be properly selected, and the generator kV and kW limits should be programmed. Refer
to chapter 3.
It is recommended that the tube(s) be conditioned (seasoned) before beginning tube auto
calibration; refer to chapter 6.
2.9.0 FINAL CHECKS
The room interface connections may now be completed. These items are described in 2.5.8.
• When finished all wiring, check that all connections are tight and secure.
• Check that all cables are dressed neatly inside the main cabinet, and secured as necessary.
• Reconnect any grounds that have been removed from covers. Then reinstall all covers before placing
the generator into service.

2.10.0 UTILITY SOFTWARE
The optional CPI utility software allows for data communication between the console and an external
computer. This provides a “virtual storage oscilloscope” that displays key waveforms and displays data
not otherwise available, and allows uploading and downloading of EEPROM, tube, and APR data. It also
allows editing of film / screen names and APR text.
A computer with an RS-232 port (i.e. laptop) and a serial cable are required to run the utility
software and to interface to the console. The serial cable to connect to the console is a special cable that
must be ordered from the factory. The part number of this cable to order is 735184-00.

3.2.1 Inputs
The Bucky inputs, S.I.D. interlocks, room door interlock, and thermal switch inputs are opto coupled. This
means that a relay contact, transistor, or other low impedance ( ≤ 100 Ω, 10 mA current rating) switching
device must be connected across each of those inputs. Table 3-1 below defines the pinouts, polarity at the
terminals

3.5.1 Calibration
The calibration function automatically establishes calibration curves relating filament current to tube current
(mA) at three or four kV settings, depending on generator type. This allows the generator to predict the
filament temperature (filament current) that will be required for any mA value over the full kV operating range.
It is recommended that the X-ray tube be seasoned before attempting auto calibration, particularly if
the tube has not been used for some time. Refer to Chapter 6 for the procedure to do this.
Use these steps to perform the X-ray tube auto calibration function:

This section applies to generators with optional AEC only.
This section contains background information relevant to AEC operation. It is strongly suggested that this be
read and understood prior to beginning AEC calibration.
3.7.1
3.7.1 AEC Limi tation s: Minimu m and Maximum Exposu re Times
• Due to various delays inherent in the AEC chamber and generator electronics, minimum AEC exposure
times should be greater than 10 ms.
• AEC exposures should normally be kept well under one second. When X-ray techniques are used that
result in longer exposures, the film density will not be correct due to film reciprocity failure.
• Care must be exercised when using low kV values with table Buckys because most table tops and grids
absorb considerable radiation in the range of 60 - 65 kVp. This will adversely affect AEC operation.

• The generator must be known to be calibrated before beginning AEC calibration.
• All components (X-ray tubes, collimators, AEC chambers, etc) used during AEC calibration must be those
which will be used during procedures, and must be positioned as they will be in actual use of the X-ray
room.
• During AEC calibration, always ensure that the central ray is centered relative to the image receptor.
• Prior to placing the water absorber, ensure that the collimator is opened sufficiently to cover ALL fields on
the AEC pickup device.
• Ensure that the absorber is positioned such as to fully cover the X-ray field. The absorber must extend a
minimum of 3/8″ (10 mm) beyond the X-ray field.

• The AEC chamber(s) must be calibrated, and the AEC fields must be balanced before proceeding. This
should be done per the AEC chamber manufacturers procedure.
• AEC calibration is performed using the center field only, (left and right fields are not selectable during AEC
calibration).
• A maximum of three separate AEC calibration curves may be established (for three film screen
combinations). Each AEC calibration curve has five breakpoints, normally 55 kVp, 65 kVp, 80 kVp, 100
kVp, and 125 kVp. These are the factory defaults referenced in the following steps, but may be changed if
required by pressing kVp or ↓.

• Set the AEC reference to a mid value at the 80 kVp knee breakpoint for film / screen 1. Adjust the AEC
gain to achieve the correct film density.
• Once the AEC gain is correctly set at the 80 kVp knee breakpoint, set the correct film density at 55 kVp, 65
kVp, 100 kVp, and 125 kVp by adjusting the AEC reference at each of those breakpoints.

The relative AEC voltage gain is expressed by:
Where n ranges from 0 to 254. This means that for low values of n, there is very little slope to the AEC gain
curve. Therefore, n needs to change substantially to effect significant gain changes. For high values of n, the
AEC gain curve is quite steep, as a result minor changes in n will have a significant effect on AEC gain.

4.1.0 INTRODUCTION
This section details acceptance testing which verifies that the generator is performing within its limits. It is
recommended that this be done after the unit is installed, as prescribed in the maintenance schedule in
Chapter 6, or when components are replaced which may affect the calibration or X-ray output. Examples
of such components are the X-ray tube, HT tank, power supply control board, fil filament
ament board, CPU board,
and the AEC board.
Calibration procedures will be supplied with replacement parts in those cases where recalibration is
necessary after replacement of that assembly.

2.0 EQUIPMENT SETUP
1. Place the radiation probe above the table approximately 25 cm (10”). Select an SID of
approximately 100 cm (40”).
2. Place a lead diaphragm over the detector and adjust its height so that the X-ray beam covers the
detector but does not over radiate the sides of the ‘R’ probe. Refer to figure 1.
Figure 1: mR measurement setup
3.0 REPRODUCIBILITY
Calculate reproducibility as follows:
1. Using kV and mA/ms or mAs values per tables 1 to 4, make a series of 5 exposures.
2. Record each of the measured mR values in the appropriate table. Refer to step 3 before
beginning step 2.
3. Record the preselected mAs for each series of exposures in the header of each table. For 3 point
generators, this is the calculated mAs value where mAs = mA X time in seconds (example for
160 mA and 125 ms, mAs = 160 X 0.125 = 20 mAs).

5.0 H.V.L. EVALUATION

EVAL UATION
1. Be sure the X-ray source assembly (X-ray tube and beam limiting device) is fully assembled and
functional.
2. Use the test setup as per figure 1.
3. Set the generator as follows: 3 point generators, 80 kV, 200 mA, 50 ms, large focus. For 2 point
generators use 80 kV, 200 mA if this can be set, and 10 mAs.
4. Take a series of three exposures and record the mR values in table 10. Calculate and record the
average of the three exposures.
5. Place 2 mm of Al on top of the lead diaphragm (total of 2 mm added), repeat the exposure and
record the mR value in table 10.
6. Place an additional 1 mm of Al on top of the lead diaphragm (total of 3 mm added), repeat the
exposure; and record the mR value in table 10.
7. Place an additional 3 mm of Al on top of the lead diaphragm (total of 6 mm added), repeat the
exposure; and record the mR value in table 10.
8. The relative transmission for the average of the three mR values where no Al was added is
assigned a value of 1.00. Using that base, assign relative transmission values to the remaining
mR values. For example, if the average mR value was 247 and has a relative transmission factor
of 1.00, then 162 mR will have a relative transmission of 162 / 247 = 0.66.
9. Plot the relative transmission values in figure 1. This should produce a straight line on the graph
since the X-axis is logarithmic.
10. Interpolate to determine the HVL. The Al thickness at a relative transmission of 0.5 will be the
required HVL value.
11. Repeat steps 4 tto o 10: 3 point generators, 100 kV, 200 mA, 50 ms, large focus. For 2 point
generators use 100 kV, 200 mA if this can be set, and 10 mAs. Use table 11 to record the values
and figure 2 to plot the results
12. Table 12 and figure 3 show example HVL determination.

* The generator purges the existing X-ray tube auto calibration data before starting the auto calibration
routine and saving new calibration data. Therefore, auto calibration should be a last resort during
general troubleshooting, and should only be done to recalibrate the tube. For example, if a low mA fault
is presented, you should ensure that the generator is fully functional, and actually needs recalibration. If
calibration is attempted on a partially functional generator, the auto calibration routine may be aborted
before any calibration is done, and the generator will inhibit further exposures until the selected mA is
calibrated for the selected kV.

NOTE RE TUBE FAULT ERROR:

As briefly described in the preceeding table, LED’s D69, D70, D71, D72, or D82 on the power supply control
board indicate the type of fault that caused the stated error.
• D69 indicates high kVp ≥ 130 kVp for 125 kV generators, ≥ 160 kVp for 150 kV generators. If this is lit,
consult product support.
• D70 indicates that inverter (primary) current exceeded preset limits. If this is lit, consult product support.
• D71 indicates cathode current exceeded preset limits, usually due to an arc. If this is lit, check the X-ray
tube. The X-ray tube may be damaged or simply require seasoning. Refer to Chapter 6 for TUBE
CONDITIONING / SEASONING. If this does not solve the problem, check the HT cables and HT
connections. Consult product support if the previous steps fail to resolve the problem.
• D72 indicates anode current exceeded preset limits, usually due to an arc. Follow the recommendations
for D71.
• D82 indicates an inverter fault. If this is lit, consult product support.

6.1.0 INTRODUCTION
This Chapter provides a recommended schedule for periodic maintenance of the X-ray generator. Instructions
are also included for installing an AEC / CAEC board in generators which originally did not have the AEC
option installed, and for installing
i nstalling an AEC / CAEC board to upgrade to CAEC (where available).
The initial installation date and location, and all service performed on the generator, should be
recorded in table 6-1. The record should be as thorough as possible, detailing the scope and type of work that
was performed (all service and a record of all replacement parts that were installed). Additionally, the person
performing the work should date and sign the record.
This information will be invaluable in the future for traceability and to ensure continued compatibility of
the generator.
If a major

6.4.0 OIL FILL / LEVEL CHECHECKCK

The insulating oil level in the HT transformer does NOT require periodic checking under normal conditions.
However, if there is evidence of possible oil loss, the procedure for checking the correct oil level
l evel follows.
1. Loosen the oil fill plug screw on the tank lid.
2. With the screw sufficiently loosened, remove the rubber (neoprene) plug.

lid.
• Normally the oil level should be between 0.88 - 1.25 inches (22 - 32 mm) from the top of the tank
lid.
• If the oil level is between 1.25 - 1.6 inches (32 - 41 mm) from the top of the tank lid, then clean oil
should be added as needed.
• If the oil level is greater than 1.6 inches (41 mm) below the top of the tank lid, please consult the
factory.
4. Use only fresh oil, type Shell DIALA AX or equivalent. It is critical that air is not added when topping up
the oil. The following procedure is strongly recommended when adding oil.
• Use a new clean syringe to remove oil from the container. A 60 cc catheter tip syringe is
recommended. Approximately 60 cc of oil is required to raise the oil level by one millimeter.
• Turn the syringe upright and expel any trapped air.
• Place the tip of the syringe through the oil-fill plug and into the oil, ensuring that it is below the
surface of the oil.
• Gently eject the oil from the syringe into the HT tank, while making sure that the tip of the syringe
remains below the surface of the oil until all of the oil is emptied from the syringe.
• Repeat the previous steps until the required amount of oil has been added.
5. Replace the oil fill plug and tighten the screw when finished. Do NOT over tighten the screw. This
should be tightened until the neoprene plug is no longer able to be turned by hand, then tighten the
screw another 1 to 1 1/2 turns. Wipe up any oil spills. Dispose of soiled absorber in compliance with
government requirements, and ensure conformity to local disposal regulations.

polishes.
• Ensure that no water or other liquid can enter any equipment. This precaution prevents short circuits and
corrosion forming on components.
• Methods of disinfection used must conform to legal regulations and guidelines regarding disinfection and
explosion protection.
• If disinfectants are used which form explosive
explosi ve mixtures of gases, these gases must have dissipated before
switching on the equipment again.
• Disinfection by spraying is not recommended because the disi
disinfectant
nfectant may enter the X-ray equipment.
• If room disinfection is done with an atomizer, it is recommended that the equipment be switched OFF,
allowed to cool down and covered with a plastic sheet. When the disinfectant mist has subsided, the
plastic sheet may be removed and the equipment be disinfected by wiping.

6.8.0 TUBE CONDITION

CONDITIONING
ING / SEASONING
Tube conditioning or “seasoning” is particularly important for new X-ray tubes or tubes that have not been
used for several days. This should be performed before attempting auto calibration, as an unseasoned tube
may not operate properly at higher kV values without arcing.
Always refer to the X-ray tube manufacturers seasoning procedure, if available. If the X-ray tube
manufacturers instructions are not available, the following procedure may be used:
IF DEVIATING FROM THE PROCEDURE BELOW, IT MUST BE UNDERSTOOD THAT THE GENERATOR
WILL NOT ALLOW EXPOSURES AT KV VALUES HIGHER THAN HAS BEEN AUTO CALIBRATED. FOR
EXAMPLE, IF AUTO CALIBRATION HAS ONLY BEEN DONE AT 40 AND 70 KV, THEN EXPOSURES
AB OVE 70 KV ARE NOT ALL OWED.
TUBE AUTO CALIBRATION IS DONE AT 40 kV, 70 KV, 100 KV, AND 125 KV. THE HIGHER KV
VALUES WILL NOT BE CALIBRATED IF LIMITED BY THE “ KV MAX” SET

MENU.
1. In the level 2 utilities menu record the current maximum kV setting, then temporarily set the maximum
kV to 80. Refer to Chapter 3 for the procedure to do this.
2. Start the tube auto calibration sequence, and allow the generator to finish the 70 kV calibration step.
Calibration will not be attempted at higher kV due to the kV limit set in step 1.
3. Season the tube at 70 kV, large focus, 300 mA, by taking approximately 10 exposures of 50 mAs.
These exposures should be taken at the maximum rate that the duty cycle limit will allow.
4.
4. Temporarily set the maximum kV to 110 kV as per step 1.
5. Restart the tube auto calibration sequence, and allow the generator to finish the 100 kV calibration
step. Calibration will not be attempted at higher kV due to the kV limit set in the previous step.
THE GENERATOR WILL BEGIN AUTO CALIBRATION AT 40 KV EACH TIME TIME THE AUTO

SEQUENCE IS RESTARTED IN THIS PROCEDURE.
6. Season the tube at 100 kV, large focus, 300 mA, by taking approximately 10 exposures of 50 mAs.
These exposures should be taken at the maximum rate that the duty cycle limit will allow.
7. Reset the maximum kV to the value that it was in step 1 prior to the temporary change.
8. Season the tube at 120 kV, large focus, 300 mA, if the kV limit allows this, by taking approximately 5
exposures of 50 mAs. These exposures should be taken at the maximum rate that the duty cycle limit
will allow.
