1 Introduction

1.1 GENERAL

Instrumentarium Dental Orthopantomograph® OP100 is a panoramic xray equipment for producing images of dentition, TM-joints and skull with the possibility of linear tomography programs for producing longitudinal and cross-sectional tomograms of the dentition. This software can be used with any OP100 or OC100 model including OP100 CR, OP100 OT and all digital models. In this manual name OP100 is used as general name for all models unless stated otherwise.

The software is divided into two parts. User programs (Pr) are accessible by the user and they have features for configuring their unit for daily use and for changing technique factors to optimize image quality. Maintenance & Service programs (Sr) are for technical people during installation and service. Please refer to User Program chapter in OP100 User Manual for Pr program details.

1 Introduction

Letters Pr or Sr in the kV display indicate that the unit is in the user or service programming mode. Numbers in the mA display indicate the actual numeric code for each program. Letters in the exposure time display indicate the mnemonic explanation for each program, to remind the user of the actual numeric program code meaning.

After you have set OP100 to the service programming mode, different service programs can be selected by pressing up and down buttons, until the desired service program code appears on the display. The display indicates the service program in the following form:

2.3 SR 72 LCA: LATERAL TMJ IMAGE AREA

ADJUSTMENT

(for film units only)

This program may be needed when cassette movement microswitches are adjusted or replaced and when the CPU board or its EEPROM is replaced. In cassette holders with optical sensors no adjustment is usually necessary.

With imaging program P7 (TMJ Lateral view jaw closed and open) first two jaws are exposed and shown on the film edges, then the second exposure is started on the return movement and images are shown in the middle. The center pair image area can be adjusted to be symmetric in respect to the other image pair by using this program, instead of adjusting microswitches. The adjustment is -10...+2.5 mm, in steps of 0.1 mm (-

1.00...+0.25 cm in the display).

Procedure:

1 Use customers latest TMJ Lateral view jaw closed and open x-ray

film, or take one:

2 Select imaging Program P7, lowest technique factors and take the

exposure. Process the film.

3 Check the film for center image pair symmetry. Calculate the amount

(-0.25...+1.00 cm) of correction needed.

4 Select program Sr 72 LCA to enter the service programming mode.

Control panel shows a number from -0.25 to 1.00. The number

5 Use left and right buttons in order to shift the middle image pair in

steps of 0.5 mm to the left or right, respectively when the film has a side marking “ L “ on the right.

6 Press OK to store these changes into OP100 memory. OP100 will

display Sr 72 LCA again. Select another program or exit the service programming mode.

7 Exit the service programming mode by switching the OP100 power

off. Turn OP100 on again. Select imaging program 7 and lowest technique factors. Take the exposure. Process the film. Check the film for symmetry. If the result was not satisfactory, return to Sr 72 LCA program and repeat steps 1 to 6.

2.4 SR 74 IOC: CPU INPUT OUTPUT CHECK

This program is used for checking the state of the CPU inputs and outputs

- without opening all the covers of OP100 main assemblies. It is useful for trouble shooting CPU input signal problems, eg. the various microswitches, user buttons and opto couplers.

Select Sr 74 IOC from the control panel. Use left and right buttons to switch between the different displayed fields. There are multiple fields (around 24) which display different ”shell variables”. The values of the input / output variables is displayed with the LEDs on the control panel and the current field with a number and either H (high byte) or L (low byte) along the number.

The program shows whether the signal from some particular switch reaches the CPU or not. The output signals are somewhat arbitrary, but the information may be useful in some situations.

1 Select Sr 74 IOC and press OK.

2 Use left and right buttons to select different tests (0L - 0H - 1L - 1H -

2L - 2H - 3L - 3H - 4L - 4H - 5L - 5H - 6L - 6H).

3 Some of the program selection LED’s on the control panel are lit

showing the state of the signal port; LED 1 (standard panoramic program) being bit 0 of the port and LED 2 (child panoramic) being bit 1 etc.

4 Use the tables of the input and output signals with the corresponding

I/O port and bit. Use CPU Board schematics to follow signals and refer also to other volumes of the Service Manual for various microswitch states.

2.8 SR 80 CRL: MOTOR MOVEMENT TEST

Select Sr 80 CrL. The procedure allows test drives for different procedures with and without exposure. The used motor can be selected with the lowest field and is shown in the kV display as either CA (cassette), ro (rotation) or LI (linear) with film units. In digital models CA is replaced by CE (cephalostat). In the test mode the carriage is driven from the start of the current position to the end (as long as the exposure button is held down.) The final display shows the accumulated error at the end of the procedure in percent (unless too big movement error which results in failure!). The speeds and accelerations are much above the normal values and motor specific.

During routine service, the movement tests need to be done for each movement motor only once in each direction with speed factor 1 and number of accelerations 2. (See the following detailed instructions, steps 4 and 5!). Further testing is necessary for extensive troubleshooting only.

The purpose of this program is to check that there is enough torque in the rotational, linear or cassette movement: the stepping motor and motor control circuit operate properly, there is enough friction and the movement does not slip nor get stuck. Tests are to be done in both directions separately.

Procedure:

1 Select program Sr 80 CrL. Movement test is activated by pressing

and holding down the exposure button.

2 The kV display shows the type of motor movement (CA, CE, ro or LI).

3 The mA display shows the amount (1-5) of accelerations per one

movement. The amount tells how many accelerating movement are done in one stroke.

4 The time display shows the velocity factor 0.1-2.5. This can be altered

manually to perform the test with different speeds.

The minimum requirements for CA, CE, ro and LI movement tests: 2 accelerations and velocity factor 1.

The other value choices are for more precise trouble shooting investigation for the movements.

Movement is done according to settings and only to one direction at a time. At the end the displayed value in the time field should be written down. Then the value shall be confirmed by pressing OK and the test movement can be done to the other direction. The second final value should be written down also. These two values should be compared to each other and the result should either be accepted or rejected according to the limit values shown on the table below.

Procedure:

1 Select Sr 90 PIn and press OK.

The mA and kV display show active exposure values and the time display the exposure time. These can be edited (free kV editing.) The exposure mode toggles between different functions for the exposure:

AEC mode Manual mode Test mode

Automatic mode selects the AEC calibration test; the time display shows the AEC frequency during exposure.

Manual mode selects exposure w/o movements; only a static exposure is done.

For film units only, the

test mode shows the

AEC base frequency

in the time display,

but no radiation is

actually done.

5,0 ± 0,3

144 ± 3

When calibrating the AEC frequency, the tube head front cover must be on and the aluminium calibration tool (code 60441) must be attached with tape right in front of the primary collimator.

2 Select the technique factors, kV, mA and exposure time. Make the

exposure. Cassette is not required, as this program does not detect the cassette sensors, however the cassette needs to be in place and centered when checking the AEC frequency during exposure for film units. Read the AEC frequency from the time field, verify the beam alignment on the fluorescent tool or capture the EPS image by CliniView (digital units).

If AEC frequency is correct (144 kHz) the middle led is illuminating. If some other led is illuminating the AEC frequency must be adjusted with potentiometer.

This AEC frequency adjustment is for digital units only.
