SECTION 1 INTRODUCTION
The Generator contains many self-diagnostic routines which greatly facilitate
troubleshooting. Self-diagnostic functions require that all microprocessors
function correctly. Each microprocessor contains LEDs that indicate its correct
operation.
As a general rule, the first step in any troubleshooting procedure is to verify
correct Power Supply Voltages and perform a visual inspection of all Boards
and Cable connections.
On arrival in the X-ray Room, the Service Engineer should carry out the
following operations:
• If the Generator cannot be Powered up, run the troubleshooting for Error
Code E01.
HF Series Generators
Troubleshooting
• If the Generator can be Powered up:
G Check which Error Code is displayed on the Console and run the
troubleshooting routines for the last Error Code displayed.
G If it is not, try to reproduce the failure in the conditions reported by
the Operator. It is possible that the Error Code displayed is
different from either that indicated by the Operator. In all cases,
run the troubleshooting routines for the last Error Code displayed.
When any major component, such as a X-ray Tube,
HV Transformer or Circuit Board, is replaced in the system,
perform the respective Configuration and Calibration
procedures.
If the HT Controller Board or the ATP Console CPU Board are
replaced, check specifically that the Extended Memory data
have not been lost or modified with the Board change.
Compare Extended Memory data displayed on the Console
with the values noted in the Data Book.
If the HT Controller Board is replaced in the Power Module,
transfer U3-EEPROM from the old Board to th e new Board.
U3-EEPROM contains calibration data and if U3-EEPROM is
not transferred a complete Calibration must be performed.
TR-1005R4
Also, make some exposures using different techniques and
Focal Spots to verify that mA stations are calibrated
correctly, if not perform Calibration procedures.
Update and record in the Data Book any new data entered in
the Extended Memory Locations.

Note .
No adjustments are required for both voltage measurements. The
ATP Console CPU Board may be located inside the Console or
inside the Generator Cabinet.
2.2 MICROPROCESSORS AND GENERAL OPERATION
The following LEDs indicate the proper operation of each Microprocessor in the
Generator:
• The LED DS1 located on the HT Controller Board blinks fast during
power up, then slows to a steady blink of about 2 per second, indicating
that the Microprocessor U5 is operating normally.
• The LED DS2 located on the ATP Console CPU Board normally blinks
at the same rate as LED DS1 on the HT Controller Board, indicating that
the Console Microprocessor U30 is operating correctly.
• The LED DS1 located on the Fluoro CPU Board only blinks in Fluoro
mode indicating that the Fluoro Microprocessor is operating correctly.
Also observe the following LEDs to facilitate general troubleshooting:
• When LED DS1 located on the Interface Control Board is ON (lit), it
indicates that the Generator is ON.
• The LED DS1 located on the ATP Console CPU Board is normally ON

2.3 REPLACEMENT OF MEMORY IN ATP CONSOLE CPU BOARD AND/OR
HT CONTROLLER BOARD
Before starting up the system, you have to set ON the switch A3024SW2--3 at
the ATP Console CPU Board to enable Service Mode. A few seconds after
pressing the ON button on theConsole, you will see E10 (this is shown because
the EPROM U24 has been replaced).
Reset the error indication by pressing the respective button on the Console and
keep it pressed until the Error 10 disappears.
After this, the normal start up will take place.
We recommend setting this switch back to OFF once the installation has been
completed. This will not enable the operator to enter in Configuration or in
Calibration Mode (Service Modes).
2.4 PROCEDURES RELATED TO THE PUSH-BUTTON CONSOLES
2.4.1 APR OPERATION
APR techniques are factory pre-programmed to standard techniques sets. All
parameters of APR techniques may be manually rewritten as required by the
operator and stored in the”APR working file”forlateruse(refer to therespective
Operator Manual).

Board.
APR re-initialization set the APR techniques only for the selected workstation.
To re-initialize the APR techniques, exit the APR mode and press
simultaneously the push-buttons 5-6-7-8 on the APR module. (Refer to
Illustration 2-2).
The APR re- initialization deletes all the APR parameters and
related selections previously modified and stored by the
operator for both X-ray Tubes.
2.4.3 APR BACKUP
2.4.4 APR RESTORE
The APR backup makes a copy of the parameters and selections of the APR
techniques stored in the U23-NVRAM to the U18-E2PROM of the ATP Console
CPU Board. This action make a copy of all the APR techniques stored in the
“APR working file”tothe“APR backup file”.
The APR backup is automatically performed when the equipment is turned
OFF/ON, whenever any APR technique has been modified and stored in the
U23-NVRAM by the operator.
To backup the APR techniques, exit the APR mode and press simultaneously
push-buttons 1-5-6 of the APR module. (Refer to Illustration 2-2).
The APR Restore makes a copy of the parameters and selections of the APR
techniques stored in the U18-E2PROM to the U23-NVRAM of the ATP Console
CPU Board. This action replaces the data stored in the “APR working file”by
thedatastoredinthe“APR backup file” for all the APR techniques.
The APR Restore is automatically performed when the Console is turned
OFF-ON, whenever any problem had been detected during the U23-NVRAM
checksum.
To restore the APR techniques, turn the Console ON and with the APR mode
OFF press simultaneously the push-buttons 4-7-8 of the APR module. (Refer
to Illustration 2-2).

4. Identify the positive and negative poles of the Battery to be measured.
Measuring the output voltage of the Battery is not enough to determine
whether a Battery is OK. The image bellow shows the measurement of
a Battery which has good voltage (around 12V) as shown in the
Multimeter.
This measurement can lead us to the thought that the Battery is in good
condition, but this is a voltage without load.

5. Connect the Load Resistance (3 Ohms, > 50 Watts) to the positive and
negative Battery poles. Repeat the voltage measurement with the Load
Resistance connected. If the voltage with load is less than 10 V (usually
close to 0 V), the Battery is not good since it will never be completely
loaded.
BE CAREFUL WITH THE LOAD RESISTANCE AS IT MAY GET
VERY HOT DURING THE TEST.

2.7 PROCEDURES RELATED TO THE CAPACITOR ASSISTED GENERATORS
CAREFULLY HANDLE ALL INTERNAL PARTS OF THE
EQUIPMENT, SPECIALLY PARTS UNDER COVERS.
DANGEROUS DC VOLTAGE IS PRESENT IN THE UNIT EVEN
IF IT IS UNPLUGGED FROM THE AC LINE.
NEVER TOUCH META L PARTS UNDER COVERS BEFORE
TESTING THAT VOLTAGE IS BELOW 10 VDC. PERFORMTHE
PROCEDURE FOR CAPACITORS DISCHARGING AND
VOLTAGE TESTING PREVIOUS TO MANIPULATE INSIDE
THE GENERATOR FOR SERVICE.
KEEP IN MIND THE GENERAL CAUTIONS FOR CAPACITOR
ASSISTED GENERATORS INDICATED IN SECTION 1.2.
2.7.1 PROCEDURE FOR STORAGE CAPACITORS DISCHARGING AND VOLTAGE TESTING
1. With the Generator turned OFF, be sure that the Power Supply Cable is
unplugged from the Mains socket.
2. Take away the Generator cover.
3. Carefully, remove the Protection Cover over the Capacitor Charger
Board (A3517--xx). DO NOT TOUCH ANY METAL PART UNDER
COVERS UNTIL THE CAPACITORS ARE FULLY DISCHARGED
AFTER THIS PROCEDURE.
4. Resistor 8R1 (1K5 ohms, 250 W) is assembles close to the Capacitor
Charger Board to allow the Capacitors discharging. Connector J4 (from
this resistor) must be disconnected for normal operation of the Unit, and
ONLY MUST BE CONNECTED to the J4 of the Capactitor Charger
Board for Capacitors discharging process.
5. Plug Connector J4 in the Capacitor Charging Board. Check that LEDs
D48 and D49 of this Board are blinking. When the Capacitors are fully
discharged, both LEDs will be OFF. Capacitors will be discharged from
800 VDC (fully charged) to 10 VDC in approximately 5 minutes.

6. Check that the voltage stored in Capacitors is < 10 VDC (maximum
voltage for a safe service manipulation). It is recommended that voltage
will be close to 0 VDC. For that, check that LEDs D48 and D49 are OFF,
and then measure the voltage at the base of Fuses 8F3 and 8F4.

SECTION 3 SELF- DIAGNOSIS INDICATORS
Some Console are provided with Self-Diagnosis indicators that identify a
malfunction in the system alerting operator about error existence that inhibits
exposure. During normal operation of the system, these indicators are directly
shown on the Console (depending on the Console model they can be shown
on the APR Display, Console Indicators, Warning Messages Area, etc).
DOOR OPEN: Indicatesthe X-rayroom door is open when the X-ray equipment
DOOR
G.OVL
is in use. (Also refer to Error Code “E35”).
GENERATOR OVERLOAD: Indicates that the exposure has been interrupted
because during exposure has been produced arcing or bad function on the HV
circuitry (X-ray Tube, HV Transformer and/or HV Cables) or a failure of IGBT
module (overheated or defective IGBTs) has been detected. (Also refer to Error
Code “E09”).

It can be also shown making a high power and long exposure with the X-ray tube
cool (X-ray Tube has not been warmed-up).
TUBE OVERLOAD: Indicates that either the technique selected is beyond the
X-ray tube ratings or the present conditions of the X-ray tube inhibit the
exposure (anode overheated). Parameters for next exposure may be
temporally limited by the Generator (change the exposure values or wait for the
X-ray tube to cool). (Also refer to Error Code “E37”).
Check that heat units available are lower than the calculated for the next
exposure. Reduce exposure factors or wait for the X-ray tube to cool.
ROTOR ERROR: Indicates that the X-ray tube anode is not rotating while
“Prep” is active, then exposures are inhibited. (Also refer to Error Code “E18”).
HEAT: Indicates that the X-ray Tube thermostat / pressurestat is open due to
overheating of the tube housing (housing is too hot, wait for the housing to cool)
or to a thermostat / pressurestat mal-function (housing is cool). Heat units may
raise to any value. (Also refer to Error Code “E36”).

TECH
TECHNIQUE ERROR: If it activates during exposure it means that:
The exposure has been interrupted by the “Security Timer”
because of a system failure. Call Field Service. (Also refer
to Error Code “E34”).
This error can also be shown:
• after an APR technique selection to advise that exposure parameters
displayed on the Console are not the values stored for this APR
technique. Exposure parameters are adapted by the Generator to
another enable values. (Also refer to Error Code “E34”).
• after the “ABC” selection, when ABC is not enable. (Also refer t o Error
Code “E34”).
• if a failure on the Automatic Collimator has been detected (blades are full
open or in movement during exposure, etc.). In this case the indicator
light is constant (not blinking). (Also refer to Error Code “E48”).

Troubleshooting
A. PRELIMINARY
1. Select minimum kVp , minimum mA, and 80 ms (for example 40 kVp, 10mA, and 80 ms). Make
preparation and check that anode rotates in the X-ray Tube. If the anode is not rotating correctly,
check the starter and the Stator connections.
2. In case the anode is rotating correctly, make an exposure:
G If “09” or “Generator Overload” appears follow procedurein paragraph B (Inverter Module
Test) .
G If not, follow step-3.
3. Increment kVp in 10 kVp steps, select the same mA and time. Make an exposure:
G If “E09” or “Generator Overload” appears, or the exposure is cut before 80 ms, then follow
procedure in paragraph C (HV Transformer Test).
G If not, keep on increasing the kVp in 10 kVp steps (60, 70, 80, 90, 100, 110, 120 and 125
kVp for 125 kVp HV Transformers; and 130, 140, 150 kVp for 150 kVp HV Transformers)
making Exposures at each kVp selected.
-- If “E09” or “Generator Overload” appears or the exposure is cut before 80 ms at any
kVp selected, follow procedure in paragraph C (HV Transformer Test).
-- If “E09” or “Generator Overload” has not appeared at the maximum kVp or the
exposure was not cut before 80 ms , it means that HV Transformer and HV Cables are
OK. Then follow the procedure in paragraph E. In this case high mA causes E09 or
“Generator Overload”.
B. INVERTER MODULE TEST
1. Power off Generator and mains.
2. Remove the cover from the Generator Cabinet.
3. Wait for the DC Bus of the Inverter to be fully discharged. When it is fully discharged the Leds
on the Charge-Discharge Monitor Board will be completely turned off.
4. When Leds are off make a jumper between DC-BUS+ and DC--BUS-- . Make sure that there is
less than 10 VDC across the BUS. (Refer to Illustration 4-1 to see where to make the jumper).
5. Measure with a Multimeter in Diode (or ohms) between C2E1 (positive polarity) and E2 or C1
(negative polarity) in both IGBTs (refer to Illustration 4-1 for more details). Repeat the measure
with different polarity between C2E1 (negative polarity) and E2 or C1 (positive polarity).
Voltage should be around 0.3 V (or the resistance must be a high impedance) for the IGBT to
be OK. Normally when an IGBT is broken the voltage is = 0 volts (or theresistance is zeroOhms)
or very close.

Troubleshooting
Note .
Don’t forget to remove the jumper across the DC Bus after all measurements are
made, otherwise the Inverter will suffer serious damage.
7. If any of the IGBTs are short-circuited, replace the IGBT.
8. If both IGBTs are OK, remove both shielded cable that connect the Inverter to the HV
Transformer: P1, P3 and SHLD (P2) . Isolate the three wires completely from each other and
from the metal sheet or ground. Make sure that wires are perfectly isolated and that no
short-circuit is made otherwise serious damages could result.
9. Set Dip-switch 3000SW2--2 in ON position at the HT Controller Board.
10. Turn ON mains and Generator.
11. Make an exposure:
G If “E09” or “Generator Overload” appear or the exposure has not been cut before 80ms,

3. Make an exposure and check that both waveforms are almost symmetric (a difference of ±10%
is normal).
G If it is OK, follow procedure in step-4.
G If it is not OK, check:
-- that in the mA Test Point of the HV Transformer the jumper is correctly placed and
secure.
-- that connector J1 is correctly placed and secure in the HV Transformer.
-- continuity between J1-D and P4-7, J1-E and P4-6, J1-BandP4-2, and J1-C and P4-1.
Check that they are correctly connected and secure.
-- if after these actions the waveform is not OK, replace HV Transformer.
4. Turn OFF Generator and mains.
5. Remove HV Cables from the HV Transformer (anode and cathode) and fill the HV Receptacles

12. Repeat the above procedure for the X-ray Tube-2 if the room has two tubes.
13. If everything is OK, it means that HV Transformer is OK and the problem could be in the X-ray
Tube or in the HV Cables. To know when the Tube begins to arc follow procedure in parragraph
D. At any case, X-ray Tube must be replaced.
14. Set on the HT Controller Dip-switch SW2 position 4 in OFF and remove jumper between FIL
(TP8) and + 5 V (TP2).
D. X-RAY TUBE TEST
After the performance of the above referred test everything is found OK, the Service Engineer may
want to know the actual status of the tube. Perform the following procedure in order to determine the
point in which the X-ray Tube begins to arc, it is strongly recommended to replace the tube as soon
as possible to prevent potential damage to the Generator.
1. Select minimum kVp and minimum mA and 100 ms.
2. Make an exposure.
3. Increment kVp in 10 kVp steps, select same mA and time. Make an exposure.
G If “E09” or “Generator Overload” appears follow procedure in step C.1 (HV Transformer
Test) .
G If not, keep on incrementing the kVp in steps of 10 kVp (60, 70, 80, 90, 100, 110, 120 and
125 kVp for 125 kVp HV Transformers; and 130, 140, 150 kVp HV Transformers) making
exposures at each kVp selected.
-- If “E09” or “Generator Overload” appears at any kVp selected it means that the tube
has dielectric problems above the selected kVp.
• If “E09” or “Generator Overload” does not appear up to maximum kVp, it means that arcing may
be due to mA or kW, follow procedure in step-4.
4. Select minimum kVp and minimum mA. Increment the mA one station and make an Exposure.
Keep on incrementing the mA station (making exposures) until “E09” or “Generator Overload”
appears. This will give an idea of the maximum mA allowed by the tube without arcing. If “E09”
or “Generator Overload” does not appear follow step-5.
5. If the tube still does not arc, the problem is related to kW=KV*mA. Make selections on the
Console at 100 ms incrementing kVand mA. A point will be reached in which “E09” or “Generator
Overload” will appear. This will give an idea on the approximate value of kVp and mA that can
be handled by the X-ray Tube. Also, this value may change when the tube heats up.

E. RANDOM “E09” OR “GENERATOR OVERLOAD”
If everything is OK and random “E09” or “Generator Overload” appears, check:
1. That the signal IGBT FAULT on Pin 3 of P5 on the HT Controller Board is not low (logic 0) in
stand-by and during the exposure. If there is noise, check loose connection between Pin 3 of
P5 on HT Controller Board, and Pin 4 of J2 in both IPM Driver Boards
2. If IGBT FAUL T is active during an exposure, try to isolate when it occurs. It may be due to noise
coming from any device outside the Generator (Bucky, Fluoro devices, etc.). Or it may occur
when selecting a high power Exposure and the voltage of the main line goes down more than
10% (in this case check the part number of the IPM DriverBoard, it must be A3063-03 or greater).

ERROR CODE : E12
DESCRIPTION : No mA during exposure or mA out of tolerance. Wrong filament current.
ERROR TYPE : Informative.
APPLICABLE TO : All Generators
APPEARS WHEN : After exposition.
INFORMATION / SYMPTOM : Error 12 appears after the Exposure to alert the operator that the mA at the start of the exposure has
POSIBLE CAUSES
not been correct. During the first 10 ms the Generator applies constant filament current to the tube.
This current is proportional to the current already calibratedfor that mA station at the kVp selected for
that Exposure (filament numbers). Near the end of these10 ms, the HT Controller reads the mA and if
they are found to be 30% under or over what has been selected, it sends error 12 to the Console.
Calibration data for kVp and mA is not correct causing error E12.
The mA jumper on the HV Transformer is open, or it is not making good contact. The mA read at the
beginning of the exposure is 50% of the correct value (because one branch is open).
There is a problem on the reading of the mA.
No correct heating prior to the Exposure. The filament has not reached its correct temperature and
the mA at the start of the exposure is low. It usually occurs when the “Prep” and “Exp” buttons are
pressed down at the same time.
Making an exposure immediately after getting out of calibration mode in extended memory.
+5 VDC , +12 VDC or --12VDC Power Supplies of HT Control Board (mesured at TP2, TP3 and TP4
of this Board) have excesive ripple or VDC measured is not correct.
ACTIONS
1. Connect a scope to thefollowing Test Points on the HT Control Boardand check that the voltage
is correct, if not adjust it with the respective Potentiometer in the Power Supply Board (refer to
Section 2.1 -- Low DC Voltage Power Supply Test):
TP2 (+5 VDC) on HT Control Board is adjusted with R12 Pot. in the Power Supply Board.
TP3 (+12 VDC) on HT Control Board is adjusted with R26 Pot. in the Power Supply Board.
TP4 (--12 VDC) on HT Control Board is adjusted with R25 Pot. in the Power Supply Board.
2. Check calibration data for the mA Open Loop (filament numbers) as stated in the Service Manual
for all combinations of kVp and mA when this error appears.
With a scope connected to the Test Point TP5 (mA) on the HT Control Board check that the mA
read is within the ratio of 1V=100 mA (± 5%) for V2 and V3 software versions, for V4 and up the
ratio is 1V=10mA from minimum mA to 80 mA and 1V=100mA from 100 mA to the maximum
rating. If it is not, the cause could be that the mA second test is not measuring correctly, or a
wrong measurement performed in the Generator. (Refer to step 3).
3. Check that the jumper in the mA Test Point of the HV Transformer is correctly placed and secure.
4. With a scope check thatduring the entire Exposure signals on TestPoints TP13 (-- mA) and TP14
(+mA) on the HT Control Board connectors are symmetrical (± 10%). If one is found missing or
not symmetrical, measure on Pin 6 and 7 of J4 on the HT Control Board. If they are symmetrical
on both Points, the problem could be on the HT Control Board. If they are not correct, check that
the connections made on the HV Transformer in J1-E, D, K terminals for Compact Generators
(in TB1, terminals 1, 4 and 5 for no Compact Generators) are correctly connected and secure.
Also check that the GND wire is connected to GND stud. If connections are correct the problem
is in the HV Transformer.

5. Connect a scope to Test Point TP5 (mA) on the HT Control Board. Check that when an exposure
is made by pressing at the same time the “Prep” and “Exp” controls, the mA at the beginning of
exposure is low. Check that when the exposure is made by pressing first the “Prep” control and
then the “Exp” control, the mA at the beginning of exposure is correct.
6. For Low Speed Generators:
G Reprogram the “Rotor Acceleration and Filament Setting Time” as stated in the Service
Manual, one step over the time as it was before (a.e.: if it was 1.2 seconds, reprogram for
1.8 seconds) and check if boosting is correctly configured.
7. For High Speed Generators:
G When performing the test for High Speed Generators check that the self-maintaining mode
is not active. In order to check if the problem disappears, select the highest mA station for
Small Focus and the lowest kVp allowed for this mA station (a.e. 40 kVp, 150 mA, SF).
Make an Exposure by pressing at the same time the ”Prep” and “Exp” controls; check that
the mA reading at the beginning of the Exposure is correct. Do the same for Large Focus
(a.e. 50 kVp, 500 mA, LF). If it is not correct, reprogram a step over at the time for each case,
and test again.

ACTIONS
1. Check 5 VDC between P1-4 and P1-3 (GND) in both IPM Driver Boards.
2. Check 115 VAC between Pins 1 and 2 of connector P2 on the same Boards.
3. If it is OK, check if the -kVp (TP12) and +kVp (TP 11) Test Points on the HT Controller Board
are symmetrical. If they are not, check signals -- kV and + kV (in Compact Generators between
P4-1 and J1-B at HV Transformer and also between P4-2 and J1-C at HV Transformer) (in no
Compact Generators between P4-1 and TB1-3 at HV Transformer and also between P4-2 and
TB1- 4at HV Transformer) if they are OK, replace the HV Transformer.
4. Check the connectors on the IPM Driver Boards. Check continuity in P3-1 (-kV DR1), P3-2
(-- kVDR2) and those signals in IPM Driver Boards. Check with a scope in TP17 (1V=33.33kVp),
if value is OK, replace HT Controller Board; if value is not OK, replace IPM Driver Boards.

APPLICABLE TO : All Battery Powered Generators.
APPEARS WHEN : At “Prep” in any Battery Powered Generators and at any moment in Generators with Stand-Alone.
INFORMATION / SYMPTOM : Battery charge level is momentarily low or some batteries are discharged or damaged.
POSIBLE CAUSES
Batteries are discharged.
Some Battery Charger Sector is not working properly or some Batteries are damaged.
ACTIONS
A. PRELIMINARY
E25 appears when the Generator has not been used for a period of time, it usually allows 2 or 3
exposures and then E25 appears.
If this is the case, charge Batteries and perform exposures until the batteries are totally discharged,
then charge again and perform exposures again to discharge, repeat the procedure 5 or 6 times. This
is the way to charge batteries fully and safe.
B. BATTERIES FULLY CHARGED AND “E25” APPEARS
1. Check Corrosion in metal contacts of Batteries.
2. Check charger Leds on Battery Charger. Green Leds and LED DS1 should be ON.
3. Check vol ta ge in J1 of Battery Charger Board: J1-16 & J1-15, J1-14 & J1-13...... , J1-2 & J1-1.
• With Generator OFF and disconnected from Mains, the voltage to be found is: 26.6 VDC.
• With Stand-Alone mode, disconnected the Generator from Mains and with the Generator turned
On, the voltage should be: 25.4 VDC.
G If voltage is not OK, check the batteries status and replace defective batteries if needed
(refer to Section 2.6.2 -- Identifying and Replacing Defective Batteries).
G If total voltage is correct and E25 appears, check the measure circuit.
-- In Generators with Stand-Alone check links between J1-18 (HT Controller) & J3-5
(Stand-Alone), J1-19 (HT Controller) & J3-6 (Stand-Alone), J1-20 (HT Controller) &
J3-7 (Stand-Alone). If links are OK and batteries voltage is OK but signals are below
minimum required (that is --BA TST3 is “0”, BATST2 is “0” and BATST1 is “1”), check
HT Controller Board and Stand-Alone Board, replace the defective Board found.
-- For Generators without Stand-Alone check that signal -BAT FAULT at P5-2 of
HT Control Board is at “High Level”.
If -BAT FAULT is at “High Level”, replace HT Controller Board.
If -BAT FAULT is at “Low Level”, check J2-2 in Battery Charger Board. If not “Low
Level” replace cable. If “Low Level“ replace the Battery Charger Board.
