6 PREVENTIVE MAINTENANCE

6.1 Cleaning

Surfaces

NOTE When cleaning the unit surfaces, always disconnect the unit from mains.

The unit surfaces can be cleaned with a soft cloth damped in a mild cleaning solution.

Stronger agents can be used for disinfecting the surfaces. We recommend Dürr System- hygiene FD 322 or respective disinfecting solution.

Film holder

The film holder can be autoclaved up to 145°C or cleaned with alcohol-based solutions.

6.2 Operation checks

Indicator light for ready status

Confirm that the green ready status indicator light comes on when the unit is ready to take an exposure.

Exposure warning indicator light and signal

Confirm that the yellow exposure warning light will come on when you take an exposure. Confirm also that the audible warning sound is heard during the exposure.

Exposure key

Confirm that the exposure key requires continuous activation to maintain the exposure.

6.3 Preventive maintenance adjustments

• Arm balance. Adjust, if needed. Refer to section 9.1 “Adjusting the balance of the arm” on page 39.

• Bracket arm angles. Adjust, if needed. Refer to section 9.3 “Adjusting the tube head’s rotational friction” on page 41.

• Stiffness of tube head’s horizontal axle. Adjust, if needed. Refer to section 9.3 “Adjusting the tube head’s rotational friction” on page 41.

• Tube head vertical stiffness. Adjust, if needed. Refer to section 9.4 “Adjusting the tube head arm’s rotational friction” on page 42.

6.5 Measuring KV / MA signals (invasive testing)

NOTE The manufacturer does not require the invasive testing. The invasive test must only be performed if the local authorities require it.

An invasive method should be used for checking the tube current (mA), and can be used for checking the kV. This method requires that the covers around the tube head assembly are removed. The analog feedback voltage signals can be measured with a calibrated multimeter.

1. Unscrew the two M4x20 DIN 7984 fastening screws of the cone.

2. Remove the tube head front cover and the cone.

3. Unscrew the six fastening screws of the tube head cover and remove the cover.

4. Attach sprung hook test leads from multimeter to P1-connector pins 1 (negative kV) and 2 (positive kV) in the tube head PCB. See figure 5.

Figure 5

5. Set multimeter to DC voltage mode with a measurement range of 1 to 5V signal level. Take 2 seconds exposure with desired kV setting. Selected mA value has no effect, however lowest possible mA should be used to minimise the amount of unnecessary radiation. When the voltage reading has been stabilized, record it.

Actual tube voltage (in volts) = 21 672 * measured feedback voltage (in volts)

The resulting tube voltage should be within ±5% of the voltage indicated in the user interface.

6. Move test leads to P1-connector pins 3 (negative mA) and 4 (positive mA).

7. Set multimeter to DC voltage mode with a measurement range of 100mV to 5V signal levels. Take 2 seconds exposure with desired mA setting. Selected kV value has no effect, however lowest possible kV should be used to minimise the amount of unnecessary radiation. When the voltage reading has been stabilized, record it.

Actual tube current (in mA) = 2.5 * measured feedback voltage (in volts)

The resulting tube current should be within ±10% of the current indicated in the user interface.

7 TROUBLESHOOTING

The control panel displays do not come on

1. Problems in mains voltage, or a fuse is blown.

Check the mains voltage. Check the mains cable. Check and replace, if necessary, the fuses located on the lower left side of the generator box. Open the generator box and check and replace, if necessary, the generator fuse F2. Replace the generator. (Perform the checks and parts replacements in this order).

2. Control panel power failure, or the control panel is defective. The control panel operates with 12 V produced on the generator low voltage supply.

Check the control panel cable and the telephone cable. Replace the control panel. (Perform the checks and parts replacements in this order).

ERROR MESSAGES

8.2 Detailed error message explanations

E.00 Exposure key was released too early during exposure

The most probable cause (if the key really was pressed firmly during the whole exposure) is faulty control panel or faulty separate exposure switch.

Replace the control panel or the separate exposure switch. Check the control panel cable, telephone cable and the arm cable.

E.10 X-ray tube anode voltage (kV) overshoot

This condition is monitored by the watch-dog circuit on the tube head PCB during the whole exposure and if the anode voltage rises above 95 kV the exposure is immediately aborted and this error indicated. A knocking sound may be heard from the tube head at the same time. This kind of arcing can occur now and then without any special reason, and should be considered a normal phenomenon. If however the occurrence frequency becomes too high, it could be an indication of a degrading tube head.

If this error occurs constantly it is probably caused by a faulty tube head or tube head PCB or generator PCB (replace in this order). The possible reason is also faulty feedback cable (9 pole) in the tube head.

E.11 X-ray tube anode voltage (kV) dropped suddenly

The x-ray tube voltage suddenly drops, and a knocking sound is heard from the tube head at the same time. The exposure is aborted and this error indicated. This phenomenon should be considered quite normal if it doesn’t occur frequently. If the generator is damaged during the exposure, or the arm/extension cable is broken, this error is indicated and during next exposure the error E.30 occurs.

E.12 X-ray tube cathode filament preheating voltages are not calibrated

The tube head PCB has been replaced, but the X-ray tube cathode filament preheating voltages are not calibrated.

See paragraph 4.3 “X-ray tube filament preheating voltage calibration” on page 17 for details how to perform the calibration.

E.13 Filament preheating voltage calibration failed

During preheat calibration the filament voltage is measured to be in specified limits. The filament circuit in the tube head or in the tube head PCB is faulty or the tube head is faulty.

Perform the calibration procedure again. If it fails, replace the tube head or tube head PCB (in this order). The possible reason is also faulty feedback cable in the tube head.

ERROR MESSAGES

E.29 Control panel key short-circuited/pressed during the self test

This error can occur only during the self-test. During the self test the unit checks that all keys are open (normal state if not pressed). If a key is found to be in short circuit, this error is displayed. Because the control panel keys are arranged in a matrix, one key’s short could cause the whole keyboard to operate erroneously, therefore this check is important.

Replace the control panel.

The factory predetermined settings are recalled and the density value is set to zero by pressing any of the keys during the self test. The error code E.29 appears on the time display, after which the right-hand preprogrammed setting key must be pressed and held down for 6 seconds. See section 5 “RECALLING THE FACTORY PREPROGRAMMED EXPOSURE VALUES” on page 26.

E.30 kV value does not reach or it exceeds the given value (difference more than 10%)

The tube voltage is sampled periodically (by the tube head CPU) and if the actual measured kV-value differs more than ± 10% from the specified value this error is displayed. The tube head, tube head PCB, generator PCB or arm/extension cable signals HV1, HV2 or KVC (see wiring diagram) can be faulty. See also error E.11 and E.34.

Check the incoming mains voltage during the exposure. Check the arm/extension cable and the tube head feedback cable. Replace the generator PCB, tube head PCB or tube head (replace in this order).

E.31 X-ray tube anode current (mA) missing, or not in specified limits

The tube current is sampled periodically (by the tube head CPU) and if the actual measured mA-value differs more that ± 20% from the specified value this error is displayed. The tube head, tube head PCB or tube head feedback cable can be faulty.

Proceed with the filament definition, see paragraph 4.3 “X-ray tube filament preheating voltage calibration” on page 17 for details. If this does not help and the error occurs constantly check the tube head feedback cable, replace the tube head PCB, or tube head (in this order).

E.33 X-ray tube filament voltage (V) missing, or outside the range (too low or too high)

The tube filament voltage is sampled periodically (by the tube head CPU) and if the actual measured filament voltage is not in the specified limits (1.0 - 4.5 V) then this error is displayed. The filament circuit in the tube head or on the tube head PCB can be faulty.

Check the tube head feedback cable. Replace the tube head PCB or the tube head (in this order).

E.34 X-ray tube anode voltage (kV) missing, or below the specified limit

This error occurs in the beginning of the exposure, when the tube anode voltage does not rise. The tube head, tube head PCB, generator PCB or arm/extension cable signals HV1, HV2 or KVC (see wiring diagram) can be faulty. See also error E.11 and E.30.

Check the incoming mains voltage during the exposure. Check the arm/extension cable and the tube head feedback cable. Replace the generator PCB, tube head PCB or tube head (replace in this order).

E.36 Too long exposure

The control panel CPU monitors the exposure time by measuring the state of the exp- signal. If, however, the tube head CPU continues the exposure more than the maximum exposure time, then the control panel CPU terminates the exposure and this error occurs. This is a safety procedure, that guarantees that the exposure is terminated under all conditions.

Replace the tube head PCB if this error occurs repeatedly.

E.37 kV feedback signal open circuit or short circuit

The kV feedback signal is monitored by the tube head CPU. The internal connection of the tube head or tube head feedback cable is faulty.

Check the condition of the feedback cable, replace the tube head PCB or the tube head (in this order).

E.38 mA feedback signal open circuit or short circuit

The mA feedback signal is monitored by the tube head CPU. The internal connection of the tube head or tube head feedback cable is faulty.

Check the condition of the feedback cable, replace the tube head PCB or the tube head (in this order).

E.50 Tube head temperature sensor short circuit

The tube head temperature sensor signal is measured by the tube head CPU. The sensor is short-circuited, the tube head PCB or the tube head feedback cable is faulty.

Check the feedback cable. Replace the temperature sensor (beside the signal connectors of the tube head), or the tube head PCB (in this order).

E.51 Tube head temperature sensor open circuit

The tube head temperature sensor signal is measured by the tube head CPU. The temperature sensor is damaged, the tube head PCB or the tube head feedback cable is faulty.

Check the feedback cable. Replace the tube head PCB.

E.52 Filament voltage feedback not in specified limits

The filament voltage is monitored by the tube head CPU. The amplifier is faulty. Replace the tube head PCB.

E.57 Exposure key pressed/failure during self test

The tube head CPU checks the state of the exp-signal when the unit is switched on. The exposure key or the separate exposure switch can be short-circuited. The arm, extension, control panel or telephone cable can be faulty. The tube head PCB or the generator PCB can be faulty.

Check the cables and the separate exposure switch. Replace the control panel, tube head PCB or the generator PCB (in this order).

The tube head CPU measures the internal voltages generated by tube head PCB power supply from the 12V operating voltage. If this error occurs before exposure, the tube head PCB is faulty. If the error occurs after the exposure, the generator 12V power supply is faulty, or the mains filtering capacitors charging circuit is faulty. The extension cable can be too long and/or the wire cross sections too small.

If the error occurs immediately after switching the unit on, replace the tube head PCB. If the error occurs only after starting the exposure, measure the 12 V voltage at the generator PCB P13 connector. If the voltage drops at the beginning of the exposure (generator’s green indicator light dims), replace the generator PCB. Check the connectors of the arm cable and the length of the extension cable, as well as the wire cross sections. The properties of extension cable are given in the figure 7 below.

E.61 Communication error between control panel and tube head CPU

The tube head PCB’s 12V voltage feed or the communication between the control panel and tube head CPU is failed. The arm/extension cable or control panel/telephone cable is faulty.

Check the cables. Measure the 12V voltage at the tube head PCB P2 connectors pins 1 and 4. Check if the red LED D7 on the tube head PCB is on. Replace the tube head PCB, control panel or the generator PCB (in this order).

E.71 FLASH memory check-sum error (tube head CPU)

Tube head CPU internal error. Replace the tube head PCB.
