PRODUCT DESCRIPTION
KEY COMPONENTS
The PROVECTA V is comprised of the following components:
a. STRAIGHT ARM AND SCISSOR ARM
Horizontal straight arms are available in 16, 24, or 35-inch lengths to meet all possible
reach requirements. The scissor arm has a double joint, enabling linear and upward
extension. The tubehead remains balanced in all positions.
b. TUBEHEAD WITH BEAM LIMITING DEVICE
70 kVp voltage and 8 mA current reduce exposure times and the amount of radiation
absorbed by the patient. The tubehead is equipped with a beam limiting device with a
20 cm (8 inches) source to skin distance and a 6 cm (2 3/8 inches) beam diameter at
the output. The tubehead is connected to the arm by means of a rotating contact,
allowing 360-degree horizontal rotation and 285-degree vertical rotation.
c. X-RAY ARM SUPPORT CONNECTION ENCLOSURE
The X-ray Arm Support Connection Enclosure mounts to the Wall Mount Plate providing
support for the straight and scissor arms and tubehead. the enclosure also provides
electrical connection points for the PROVECTA V.
d. WALL MOUNT PLATE - 16-INCH ON CENTER
The Wall Mount Plate is designed to span two 2 by 4 wall studs that are spaced 16
inches apart to provide a secure wall-mounted surface for the installation of the
PROVECTA V.
e. REMOTE X-RAY CONTROL PANEL
The Remote X-ray Control Panel is a microprocessor-controlled digital timer allowing both
manual selection and 5 automatic selections of exposure times. Automatic selection further
allows the operator to choose among 30 pre-set times according to the type of patient
(Small, Medium or Large), the type of tooth and digital or film type. 44 fixed times can be
selected manually and ranges from 0.02 seconds to 3.20 seconds. The timer automatically
compensates for input line voltage variations within a range between110 and 132V.

Selected Exposure time and Corrected Actual Exposure Time The ALLPRO X-ray Control Timer incorporates a special feature which automatically corrects the selected exposure
time when the line voltage varies from 120 V. A change in the AC line voltage affects the peak voltage applied to the
X-Ray tube and the value of high voltage significantly affects the spectrum of the radiation that ultimately affects the
optical density of the imaging media. The purpose of the X-ray Control timer correction is to obtain the same nominal optical density on the imaging media independent of the AC line voltage variations from 110-132 Volts.
The automatic correction of the exposure time works as follows:
The internal voltage measuring circuit in the X-ray Control Timer continuously monitors the AC line voltage.
When the user selects the desired exposure time and presses the X-ray Exposure button, the exposure time will
be automatically adjusted based upon the measured AC line voltage. The corrected actual exposure time will be
displayed until the X-ray Exposure button is released.
NOTE:
Electromagnetic interference between the equipment and other devices can occur. Do not use the
equipment in close conjunction with sensitive devices, or devices creating high electromagnetic
disturbances.
11
TECHNICAL SPECIFICATIONS
The corrected exposure is calculated applying a correction factor to the selected exposure time, based
on an empirical law that correlates the dose with the high voltage peak and consequently with the line
voltage. The qualitative relationship between the multiplying factor and the line voltage is shown in the
following graph:

TECHNICAL SPECIFICATIONS
TECHNICAL FACTORS MEASURING METHOD
kVp
The kVp is defined as the average of the peak high voltage after pre-heating
time and settling. The kVp is assessed with a non-invasive instrument having a
± 1% accuracy at the nominal AC input line voltage.
mA
The output current is defined as the average value of the current after pre-heating
time and settling. The output current can be measured by attaching a DC voltmeter
(0-10 VDC) to the connections behind the circular cap on the side of the Tubehead
yoke. The correlating relationship is 1 volt per mA of tube current.
t
The exposure time is defined as the time measured with a non-invasive meter.
Accuracy is verified by using an Innovision 8000 mAx instrument.

a. Set automatic exposure settings for specific patient size, media type and tooth
type per procedure of page 25.
b. Set manual exposure settings as necessary per procedure of page 26.
5. Move as far away as the hand control cable allows, in a direction opposite to the X-ray beam
emission while maintaining visual contact with the X-ray Control panel and the patient.
6. Press the X-ray Exposure button and hold it depressed throughout the entire exposure.
7. The X-ray emission condition is indicated by the illumination of the ACTIVE X-RAY EMISSION
CAUTION Indicator Lamp
and an audible signal sounding.
8.
At the end of the exposure, the system starts the Tubehead cooling cycle, which is 32 times the
exposure time. The remaining cooling time is shown on the Digital Display panel.
WARNINGS:
1.
The X-ray Exposure button is a “Dead Man” control. The button must be kept depressed throughout the
entire exposure. Releasing the button before the end of the exposure terminates the emission. When this
happens the the exposure time display flashes, while the other panel indicators extinguish. The flashing display lasts until either the INCREASE () or DECREASE () button is depressed. At that time, system operation resumes in the tubehead cooling cycle and the display shows remaining cooling time.
2.
If the combination of low AC line voltage and long exposure time results in a corrected exposure time of
more than 4.00 seconds (240 pulses), the system will inhibit the exposure. In this case, the display shows
the corrected exposure time. Reset the unit by pressing the INCREASE () or DECREASE () button and
reduce the exposure setting so as not exceed 4.00 seconds (240 pulses).
3.
If the AC line voltage reaches minimum/maximum operating limits, the display shows the following:
Error Code “LLL” denotes that the voltage is too low (under 106 Volts).
Error Code“HHH” denotes that the voltage is too high (over 134 Volts).
Contact your ALLPRO authorized Dealer for service when either code is displayed.
READING THE EXPOSURE COUNTER
1. Simultaneously press and hold the INCREASE () and DECREASE () Select Buttons for more
than 3 seconds.
2. When P20 is shown on the Digital Display panel, release the INCREASE () and DECREASE ()
Select Buttons.
3. Press either the INCREASE () or DECREASE () Select Button to display the number of
exposures in thousands (e.g. 004=4,000).
4. Press the INCREASE () or DECREASE () Select Button to display the number of exposures
up to 999 (e.g. 354).
5. The total number of exposures is 4,000 + 354 = 4,354.

RADIOGRAPH TROUBLESHOOTING
CHECKS AND CORRECTION OF POSSIBLE FAULTS IN DENTAL RADIOGRAPHS
TYPICAL DEFECTS OF INTRA-ORAL RADIOLOGY
- Light radiographs:
Possible causes:
- Insufficient exposure to X-ray (short time)
- Poor film processing technique
- Insufficient development time
- Deteriorated developer / contaminated developer
- Developer temperature below recommended value
- Incorrect developing fluid dilution
- Expired film
- Dark radiographs:
Possible causes:
- Excessive exposure to X-ray (long time)
- Film exposed to light / secondary X-ray exposure
- Poor film processing techniques
- Contaminated developer
- Excessive development time
- Developer temperature above recommended value
- Incorrect developing fluid dilution
- Expired film
- Blurred radiographs (details not visible):
Possible causes:
- The patient moved
- The tubehead moved
- Radiographs with herringbone marks:
Some intra-oral films are provided with a thin lead foil having a herringbone type mark on its lower
side. These films may be exposed to radiation on one side only. If the film is exposed on the wrong
side, the lead foil will absorb a large amount of radiation during exposure. The result will be a lighter
radiograph and the film will show herringbone marks.
29
RADIOGRAPH TROUBLESHOOTING
PARTIALLY EXPOSED RADIOGRAPHS
Possible causes:
- X-ray Tubehead positioned incorrectly with respect to the imaging media
- Low developer fluid level, with resulting partial film development
- Two or more films placed against each other during development
CLOUDED RADIOGRAPHS
Possible causes:
- Outdated film (check expiration date)
- Film accidentally exposed to X-ray
- Film accidentally exposed to other natural or artificial light sources
- Improper development technique
RADIOGRAPHS SHOWING A BLACK LINE
This line appears when the film is excessively folded
RADIOGRAPHS SHOWING SIGNS OF ELECTROSTATIC ELECTRICITY
When a film is compressed too much and the air is dry, static electricity may occur, which displays
black marks.
RADIOGRAPHS WITH CHEMICAL SPOTS
Developer or fixer fluid spattered on the film before development and fixing procedures produces
spots on the radiograph; such spots are:
- dark, when caused by developer fluid
- light when caused by fixer fluid
RADIOGRAPHS WITH EMULSION COMING OFF
If the film is kept in a hot water bath too long (e.g. throughout the whole night), or in the developer
solution too long, the emulsion may become softer and partially come off the film base. After development, the film will show scratches.
TYPICAL DEFECTS CAUSED BY INCORRECT POSITIONING
- Radiographs with elongated or shortened image:
The main beam is not perpendicular to the bisecting angle formed by the tooth longitudinal axis
and the film.
- Radiographs with stretched out tip of tooth
Probably caused by excessive film folding or bending inside patient’s mouth.
