Use in accordance with the regulations includes compliance with the instructions for mounting and usage as well as compliance with the provisions on setting up, installing and operating the machine, and on warranty. Use in accordance with the regulations also includes compliance with all legal provisions in force in the place where the machine is being used, with regard to work safety and the disposal of chemicals.

2.2 Use not in accordance with regulations

If the machine is used for a purpose other than the one stated in the regulations, the manufacturer shall not be legally liable for any damage arising as a result of same. In such cases, the user shall incur the risk.

2.3 Product information

The exposed film passes through different zones within the Dürr XR 24 PRO X-ray developing machine: the developing, fixing, rinsing and drying zones. When the machine has been switched on, the developing bath and the fixing bath are heated to the set bath temperature (e.g. 28°C) at a rate of 0.5°C/min. The machine is then ready to be operated. It starts operating automatically when a film is slid inside. The film is transported through the machine. As soon as the message “MACHINE LOADED” stops flashing on the display, another film can be introduced, or up to 6 intra-oral films, can be introduced together. When the film has passed through the whole of the machine, it switches automatically to stand-by.

6. FUNCTIONAL DESCRIPTION OF THE XR 24 PRO

When the mains button (min. 2 sec.)

heating-up phase for the developing bath and the fixing bath begins. The time remaining until the correct temperature is reached is displayed in the following manner: “WAITING TIME… MIN” (display flashes). The machine does not start at this point.

The bath begins to rotate when it is being heated up.

place, the chemicals are pumped from the developing tank and the fixing tank (volume of 5 litres for each tank) into the lifting tray (22) via the circulation pump (14).

When the set temperature is reached, the display lights up. The “MACHINE EMPTY” message appears, indicating that the machine is now ready to be operated. As soon as the set temperature falls below more than 0.5°C, the continuous heater and the circulation pump (14) are switched on again.

When a film is slid into the machine, the start flap (2) opens and the “MACHINE EMPTY” message flashes on the display At the same time, a signal for lowering the lifting tray (22) is triggered and the water valve (15) opens. The drier heating unit (10), drive motor (12) and circulating pump (14) (for rotating the developing bath and the fixing bath) start up.

The time it takes the film to pass through the machine is controlled by a tachometer

generator (12a). The lifting tank’s rising and falling movements are controlled by the disc’s and the light barrier’s (19a) rotational speed.

, the display is illuminated. The

is pressed

Should the outflow pipe be blocked, a signal is sounded via a level sensor (13). The water valve (15) closes and no more water is fed into the machine.

When the film has been slid into the machine, the start flap (2) closes. As soon as

the message “MACHINE LOADED” flashing on the display goes out, another film can be introduced, or up to 6 intra-oral films, can be introduced together. If no other film is slid into the machine when a particular film has passed through it (this is signalled by a sound) the lifting tray (22) moves upwards (to stand-by position), indicating that the machine is now empty. The drive motor (12), water valve (15) and drier heater (10) are switched off. When the machine is in stand-by position, the developer’s and fixer’s roller packets are completely immersed in the chemicals. This prevents deposits from forming on the rollers.

When the lifting tray (22) is lowered, the film is carried between the rolls through the developing bath and the fixer bath, as well as through the rinsing and drying zones (8) within the time set for same.

While the film is being developed, water is fed into the rinsing zone via water inlet (7). The water is discharged via the outflow pipe. Water flows through continuously at a rate of 2 l/min., with water pressure of 2 bar.

MOUNTING AND ASSEMBLY

7. SETTING UP

7.1 Area in which machine is to be set up

• The XR 24 PRO developing machine should

only be set up in a dry, well-aired room.

• In winter, the room temperature should not

fall below +10°C; in summer it should not rise above +28°C.

Danger. The appliance should not be directly exposed to the sun’s rays. There is a danger that the

chemicals may overheat or that the films might be pre-exposed.

• The room in which the machine is being set

up must contain a R3/4” bibcock (27) with a ventilation pipe, an outflow pipe (28) with a ventilated plastic trap, and an earthed plug (26). Ideally, a washbasin should also be situated close to the machine.

The operating staff must have easy access to the bibcock (27) and the earthed plug (26)..

• We recommend that the XR 24 PRO be set

up in a darkroom. If the machine is up in a darkroom, a daylight attachment (24) (DL24 or DL26) must be fixed to it.

• The following should be taken into

consideration if the machine is being used with a daylight attachmentwith a daylight attachment

with a daylight attachment:

with a daylight attachmentwith a daylight attachment

Danger. Films should never be stored in the vicinity of an X-ray room Danger. When films are stored in the daylight attachment’s film storage part (25), there is a danger that pre-exposure can occur due to stray radiation in the appliance.

If necessary, a partition with a lead screen may be inserted.

7.2 How to set up machine

• Set the machine up on a horizontal, stable,

even board at working height.

• When the tubes are being passed under,

the board must have an opening measuring ca. 7 x 10 m

• Ensure that additional space is available so

that servicing work can be carried out and so that the machine is adequately ventilated:

There must be at least 10 cm of free space behind the machine and ca. 50 cm free space left and right.

At the front there must be enough space in case a daylight attachment (24) has to be

fixed to the machine. If necessary, detach the installation feet at the front and screw them on to the back.

7.3 Setting up the machine

• Undo the plastic bands attached to the

cardboard packaging.

• Take out all small parts.

• Grip the sides of the machine and place it

in suitable position.

• Set it up close to a mains water supply, an

outflow pipe and an earthed pipe (max. distance 1.5 m)

• Set up the appliance so that it has a slight

tilt, ca. 0.3 ° to the fixer bath (fig. 8).

Adjust the feet of the appliance (29) using the spanner provided (30) as required.

8. INSTALLATION

8.1 Mains water supply

• Check whether or not pure water is flowing

out of the bibcock (27). When the machine

is being installed initially, rinse the pipelines thoroughly!

• Because the water quality can vary greatly

from region to region, a fine-mesh filter (32) must be inserted between the bibcock (27)

and the water pipe (34).

33 34

The fine-mesh filter (32) protects the flow-through limiter in the appliance’s water valve from impurities

• Close the bibcock (27).

• Connect the 90º bow to the bibcock (27).

Attach the fine-mesh filter (32) (arrow in flow direction) and double nipple (31) to the bibcock

Check whether the strainer (34a) and both seals (34b) are present in the water pipe’s (34) threaded joints.

• Connect the water pipe to machine’s water

intake point (35) (threaded joint with strainer) and to the double nipple (31).

34a

34b

8.2 Wastewater connection

• The wastewater connection may only be

connected via a ventilated siphon.

• Move the outflow pipe (36) to the siphon at

a continuous slant. Shorten the pipe to the

correct length.
