General Information Safety Notes CAUTION

1

When carrying out the work steps and tests, the safety notes contained in the product-specific documentation as well as the general safety notes contained in the ARTD binder must be observed.

Checks and adjustments that must be carried out with radiation switched on are marked with the radiation symbol. When performing work procedures which are marked with this symbol, radiation protective clothing must be worn.

Remarks Regarding Adjustment

1

In the control panel, there are 7-segment display components which display the operating condition and, in the event of an error, an error number. The error numbers are listed (see appendix) and indicate the subassembly that is not functioning properly. If there should be a malfunction, check the drive mechanism first. In particular, check for easy movement of the moving parts Pay particular attention to the cleaning and lubrication of rails and guide parts. Check the chain tension and toothed rack guides for each drive. If the mechanism functions properly, check the electronics.

Potentiometers

1

Potentiometers P1 to P14 are located on CPU PC board 24S1. By means of these potentiometers, the voltages for test channel adjustment are set and coated with enamel. CAUTION

Do not turn these potentiometers.

Potentiometers which can be accessed from the front are also located on the Mini-Maestro (cassette carriage), Maestro (column/spotfilm device) and small voltage PC boards. These may be adjusted only if this is described in the corresponding chapter of these adjustment instructions. The same applies to the potentiometers on I/0 PC board 24S2. With replacement of a subassembly configured with potentiometers, the potentiometers have been adjusted at the factory and may not be changed, except for the potentiometers described in these adjustment instructions.

Potentiometers, Remarks Regarding Replacement and Adjustment

1

When replacing potentiometers for actual value sensing and for their adjustment, it must be made sure that there is always minimum play between the pinion gears. The potentiometers may not be subjected to mechanical load. Only the 3PT2 potentiometer (spotfilm device) is adjusted with a play of approx. 0.5 mm to achieve smooth movement. The 3PT10 and 3PT11 potentiometers, format sensing for height and width, are heat-sensitive!

Allarmax

1

This function monitors all drives and switches off if a drive is blocked. The movement must be blocked in some adjustment steps. This function must be switched off so that a shutdown does not take place.

NOTICE

Switching off the "Allarmax" software - Insert jumpers on board 24 S2 AMP3 (for service material set)

If this jumper is not configured, in the AMP 3 connector (24 S1 board) jumper Pin 16 with 1 and Pin 15 with 2. Overview of AMP 3

General Information

IMPORTANT

If one replaced subassembly does not function properly, do not turn the potentiometers; order a new subassembly.

Lubricating Points / Bearings / Screws / Electrostaticallysensitive Devices

1

Check the condition of all accessible chains, drives, slide and roller bearing guides prior to beginning each adjustment and if needed, apply bearing grease or a similar substance (lubricants are listed in Maintenance Instructions, RXD3-209.101.01...). If parts are worn or damaged, they may be replaced only with original parts.

Installation of Ball Bearings

1

Support rollers, rollers and ball bearings are adjusted so that the unstrained outer ring can still just be turned manually.

Securing of Screws

Secure all screws removed for adjustment purposes according to their original state. Secure screws by means of appropriate lock washers, counternuts or Loctite type 221, Part No.: 20 48 874. Securing by means of Loctite, if necessary, is listed in the text. When performing work steps with Loctite, please ensure that no securing compound will penetrate into any bearings. After some days, the gearing will have seized. Loctite may be removed by using heat (electric hair-dryer etc.)

Protection of Electrostatically-sensitive Devices CAUTION

1

The integrated circuits and PC boards used in the unit must be handled with particular care due to their electrically-sensitive structures and extremely high input resistance. The rules pertaining to this handling are listed in the ARTD. It is essential to use the protective devices listed there.

24S1 CPU Board

1

After a replacement of the CPU board 24S1, the E-Prom1 and E-Prom 2 and EE-Prom U83 from the board that has been removed must be taken over. Turn the unit on and on the I/O board 24S2, set the DW 1/8 switch to ON. At the remote control console type in code 117 using the keys P31, P32, P34 and P35. Store with key P33 (see page 2 -1). On the I/O board 24S2 set the DW 1/8 switch to OFF. When the initialization that follows takes place, the switch positions of the DW1 programming switch are read in. Carry out Clock-Test/Adjust in the PC-Mode (Hardware test and Settings), see page 1 - 12 respectively 1 - 15 following.

24S2 I/O Board

Set the DIP switch DW 1/8 on the 24S2 I/O board to the OFF position. When this is done, an automatic reset takes place and the data/values that have been set are read in. However the reset key on the 24S1 CPU board can also be pressed or the unit can be switched off and back on again.

NOTICE

Pressing the reset button PL1 on the CPU board 24S1 will only bring about a reset exclusively on this board; however, no reset will take place on the CPU board 1S2 in the remote control console. A comprehensive reset will be achieved only with unit OFF and ON again.

The following short version is used for the adjustment steps. Example:

• Mechanical initial position: • Select adjustment mode - I/O board 24S2, DW 1/8 to ON - Set 011 and store (see 2-1)

• Exit the adjustment mode. - I/O board 24S2, DW 1/8 to OFF. - This allows the adjustment data to be taken over.

Belt Tension, Adjustment Procedure

• If UI 003/96 has not yet been performed, i.e., the stop (1/Fig. 5) is not installed: move the unit into the +60° to +70° position and move the exposure unit to max. head end. In this position, the force on the tilt drive is low and a release on its own is not very likely.

• If UI 003/96 has been performed and the stop (1/Fig. 5) is installed: Raise unit to +90°. • Loosen the four mounting screws (1/Fig. 3) on the motor support plate. At the adjustment screw (Detail 2/Fig. 3), turn until the Poly-V belt is lightly tensioned. The motor longitudinal axis must be parallel to the gear longitudinal axis. Tighten the mounting screws (1/Fig. 3). Check: the outside surface of the belt pulley on the drive must be flush with the level of the diameter reduction of the belt pulley on the motor (Fig. 4). If necessary, correct the position of the belt pulley on the motor in the shaft long. direction.

Auxiliary device:

Feeler gauge 0.2 mm

Adjustment conditions:

Move the unit into +60° to +70° position and move the exposure unit to max. head end. With the nuts (A/Fig. 6) set the distance of all springs to a = 10 mm. This setting corresponds to a brake momentum of approx. 50 Nm. With 60 Hz power supply the brake momentum must be approx. 60 Nm, which requires a stronger pretension of the springs. To do this, mark the nuts (A/Fig. 6) with a waterproof pen (for control purpose) and tighten them just one turn each. Evenly adjust the gap of 0.2 mm + 0.1 mm between magnet and brake disk using the nuts (B/Fig. 6).

Replacement:

If UI 003/96 has not yet been performed, i.e., the stop (1/Fig. 5) is not installed: move the unit into +60° to +70° position and move the exposure unit to max. head end. In this position, the force on the tilt drive is low and movement on its own is very unlikely. Replace the brake. If UI 003/96 has been performed and the stop (1/Fig. 5) is installed: raise unit to +90°. Turn the flywheel of the tilt motor 3MT4, against the resistance of the brake until the stop (1/Fig. 5) is securely against the unit base (2/Fig. 5). Replace the brake. Turn the flywheel o the tilt motor 3MT4 in the opposite direction as previously until the stop (1/Fig. 5) as previously is no longer against the unit base and the limit switch 3FC11 (Fig.2 + 11) is no longer actuated.

Adjustment of gap width, general remarks

11

The factory adjusted spacing width on subdivided exposures is approx. 3 mm. For the most part the spacing width depends on the positioning accuracy of the cassette carriage, for both single exposures as well as series exposures. If the customer wishes to have either a wider or narrower spacing, this can be adjusted electronically. The same spacing width on exposures with 3 or 4 subdivisions cannot be obtained due to insufficient positioning accuracy of the cassette carriage.

• Select adjustment mode I/O PC board 24S2, DW 1/8 to ON Code 184 to 181 (reduction in steps of 0.2 mm each) Code 185 (no software correction) Code 186 to 189 (increase in steps of 0.2 mm each)

• Enter the desired code and store. • Exit the adjustment mode I/O PC board 24S2, DW 1/8 to OFF

Mechanical initial position for the width: Width collimator plates closed all the way

• Before installing, set the potentiometer to 900 Ohm (Ralco), 100 Ohm (Gorla), between "CW" and "wiper"

• Take note of the direction of turn: when the width collimator opens the resistance value must increase.

• On the CPU board 24S1, measure between TP2/13,14 = 0V and TP2/7: 1,45 V (Ralco), 700 mV (Gorla). Mechanical initial position for the height: Height collimator closed completely

• Before installation, set the potentiometer to 900 Ohm (Ralco), 100 Ohm (Gorla), between "CW" and "wiper"

• Take note of the turn direction: when the height collimator opens the resistance value must increase.

• On CPU board 24S1, measure between TP2/13, 14 = 0V and TP2/8: 1,45 V (Ralco), 700 mV (Gorla).

Collimator Correction Factors for Collimator

12

With an increase of the values in a unit’s place the collimation is increased. Example: Correction of the cassette width The current value is 125. If the width is to be lowered, the value 125 is to be reduced to values between 121 and 124 with the help of the P31/32 keys. If the width is to be raised, the value 125 is to be increased to values between 126 and 129 with the help of the P31/32 keys.

Tomography Setting the spotfilm device speed

It is possible to set a tomographic height correction digitally with this software version. The starting value is Code 175 and the correction can be made in 1 mm steps downwards with Code 174 to 171 and in 1 mm steps upwards with Code 176 to 179. A prerequisite is that the code 175 is programmed before the speed of the spotfilm device is adjusted. Otherwise the correct tomographic height can not be set.

• Select adjustment mode, I/O PC board 24S2, DW 1/8 to ON, (see page 2 - 1) • Verify if code 175 is programmed, search with keys P34 and P35 only • If not, enter code 175 and store • Exit adjustment mode, I/O PC board 24S2, DW 1/8 to OFF • Connect multimeter:

NOTICE

24S1, TP2 - 4 (+) 24S1, TP2 - 14 (0V)

The multimeter must be able to display three digits after the decimal point.

• At the generator, set "SS" to off • Switch off "Allarmax" (plug in AMP3 on 24S2) • Tomography 40° • Tomographic height 200 mm • Exposure system in table center • Press prep-button and hold until the column has reached its head-end start position and the multimeter displays a stable value. Read and note down that value (value A, wiper voltage of potentiometer 3PT2). Trigger a planigraphic exposure without radiation by pressing prep- and main-button. Column travels from head end to foot end. Release prep- and main-button and subsequently press both again thus triggering another planigraphic exposure allowing the column to travel back from foot end to head end. Attention: keep prep- and mainbutton depressed until the column has reached its head-end position and the multimeter displays a stable value (value B).

• Determine the difference from both measured values A and B Required: ± 5 mV Correction: Potentiometer P2 on SP 22AZ4 (Pick-a-back board, max. Speed) clockwise: counterclockwise:

if A > B if A < B

Repeat the process until the required ± 5 mV are reached.

• Switch on "Allarmax", (pull out AMP3 on 24S2) !

• Perform tomographic exposure 40° and tomographic height 200 mm with tomographic test.

• Determine the difference of the tomographic height. • Select adjustment mode - I/O PC board 24S2, DW 1/8 to ON Code 174 to 171 (decreasing in 1 mm steps each) Code 175 (no software correction) Code 176 to 179 (increasing in 1 mm steps each)

• Enter the desired code from the above table and store • Exit the adjustment mode - I/O PC board 24S2, DW 1/8 to OFF

• Take new tomographic exposure under the same conditions. • If there is still a difference, make further corrections. • In systems with FLUOROSPOT take an indirect tomography control exposure.

NOTICE

The setting made at 40° / 200 mm applies for all tomographic angles, tomographic heights and operating modes.

• Make sure that "Allarmax" is switched back on, (jumper AMP3 on 24S2 removed) !
