7. XR 24 Pro functional description

Press the power switch (min. 2 secs)

and the display lights up. The warming-up phase for the developer and ﬁxer baths begins. The necessary waiting time required before the required temperature has been reached is shown: "WAITING . . MIN" (display panel blinks). The unit will not start during this warm-up stage.

The bath circulation process starts parallel to the bath heating. During the circulation step

the rotatory pump (14) feeds the chemicals from the developer and ﬁxer baths (tank volume of each is 5 liters) to the lifting bath (22).

Once the set temperature has been reached the display will show "MACHINE

EMPTY", i.e. the unit is now ready for use. As soon as the set temperature falls by more than 0.5 °C the process heater and rotary pump (14) will start up again.

When a ﬁlm is inserted, the ﬁlm feed ﬂap (2) opens and the display will show a blinking message: "MACHINE LOADED". At the same time a signal is triggered to lower the lifting bath (22), the water intake valve (15) is opened, and the dryer heater (10), drive motor (12) and the rotatory pump (14) (for developer and ﬁxer bath circulation) all start up. The processing time can be checked using the speed sensor (12a). The raising and lowering of the lifting bath is controlled by the rotation of the disc (driven by the lift motor (20)) and is monitored by the infrared light sensor (19a).

When the lifting bath (22) is lowered the ﬁlm is transported between the rollers and through the developer and ﬁxer baths, and then through the rinsing and drying zones (8) in the preset processing time.

During the ﬁlm processing, water is released via the water inﬂow (7) into the rinsing zone. The water is drained off via the waste water system. There is a continuous ﬂow of water of ca. 2 l/ min, at 2 bar. If the waste water drainage gets blocked, then the level indicator sensor (13) sends an audible signal, the water intake valve (15) is closed and the water inﬂow is halted.

Once the ﬁlm has been taken up the ﬁlm feed ﬂap (2) closes. As soon as the blinking message "MACHINE LOADED" on the display panel is extinguished, then a further ﬁlm or 6 intraoral ﬁlms side-by-side can be fed in.

If, after the ﬁlm processing stage (message is audible signal), no further ﬁlm is inserted, then the lifting bath (22) is raised (stand-by position "MACHINE EMPTY"). The drive motor (12), water intake valve (15) and dryer heater (10) will then be switched off. In the stand-by position the developer and ﬁxer roller set (5) is completely submerged in the chemicals. This serves to prevent the majority of any deposits attaching themselves to the rollers.

8. Set-up

8.1 Room for set-up

• The XR 24 Pro developer may only be operated in a clean, dry and well-ventilated room.

• Room temperature must not fall below +10 °C in winter and must not exceed +28 °C in summer.

• The room chosen for set-up must have access to a water connection (water tap) (27) R3/4" with pipe anti-vacuum device, waste water drainage (28) with aeration (anti-odour) via plastic siphon and an electrical safety socket (26). We strongly recommend that a wash basin be available in the vicinity of the developer.

The water tap (27) and electrical safety

socket (26) must be easily accessible to the operating personnel.

• We strongly recommend that set-up of the XR 24 Pro is effected in a darkroom. If the appliance cannot be set up in a darkroom, then a daylight cover (24) (DL 24 or DL 26) must be ﬁtted.

• When operating an appliance with daylight cover (24) please note:

Never expose the machine to direct

sunlight! Danger of the chemicals overheating or pre-exposure of ﬁlm materials. Never store ﬁlm material in the vicinity of the X-ray room!

Once ﬁlm material is inserted into the

ﬁlm depot (25) of the daylight cover there is the danger that pre-exposure can occur due to stray ambient radiation from the X-ray appliance.

• If necessary, it is possible to set up a separating wall or barrier using lead protection.

Mounting

2018/02SE 11

8.2 Set-up alternatives

• Place the developer unit onto a horizontal, stable, ﬂat, and single-piece working surface at a comfortable working height.

• In order to have access to the hoses the working surface should have at least one opening of ca. 7 x 10 cm.

• Take into account that additional space may be required for service and maintenance and that sufﬁcient ventilation is available for the unit: to the rear leave at least 10 cm, left and right allow ca. 50 cm free space

• Leave enough space at the front in case a daylight cover (24) is to be used. If necessary, unscrew the adjustable feet from the front and apply to the rear.

8.3 Set-up

• First remove the plastic tapes to the packaging and carefully lift the box upwards.

• Remove all small parts.

• Take the unit from the sides and place as

required.

• Set up the unit in the vicinity of water supply, waste water system and electrical safety socket (max. distance 1.5 m)

• Set up the appliance so that it has a slight tilt, ca. 0.3 ° to the ﬁxer bath (ﬁg. 6). Adjust the feet of the appliance (29) using the spanner provided (30) as required.

12 2018/02SE

9. Installation

9.1 Water connections

• Check that clean, clear water ﬂows from the water tap (27).

When installing for the ﬁrst time make sure the connection is allowed to ﬂow and rinse ﬁrst!

• Because of great regional differences in the water quality a ﬁne ﬁlter (32) must be ﬁtted between the water tap (27) and water hose (34).

The ﬁne ﬁlter (32) protects the ﬂow regu-

lator in the water intake valve of the appliance from becoming dirty.

• Turn off the water tap (27).

• Connect the 90° elbow piece (33) to the water

tap (27), mounting the ﬁne ﬁlter (32) (arrow in direction of ﬂow) and the double nipple piece (31) at the same time.

Check that the coarse ﬁlter (34a) and

both seals (34b) are present in the threaded ﬁtting of the water hose (34).

• Connect the water hose (34) to the water inﬂow (35) of the appliance (threaded pipe ﬁtting with coarse ﬁlter) and connect to double nipple piece (31).

9.2 Waste water connections

• The waste water connection must include a siphon trap.

• Lay the waste water hose (36) with a steady incline to the siphon trap: Shorten the hose to an appropriate length

When laying out the waste water

hoses the following must be carefully observed:

- avoid sagging hoses! Avoid squeezing or reducing the pressure on hose!

• The external ends of the hoses should be coated with UHU-Plast.

• Screw the screw socket (37) onto the hose and ﬁt to siphon trap muff (25) using a hose clamp (38).

• Secure the waste water hose using hose clamp, screws and rawlplugs.

9.3 Waste water hose connection

from developer and fixer

• Place the 10l-collector tanks (39) for developer (black level indicator marker) and ﬁxer (red level indicator marker) below the appliance in a clearly visible position and free from the possibility of tilting.

• Lay hoses (40) with constant incline

• Shorten the hoses to the correct length.

• Feed the hose for developer (black markings)

into the black cover (41).

• Screw the cover (41) of the developer collector (39) on tightly.

• Fix the hose for ﬁxer (red markings) in the same way to the ﬁxer collector.

Empty the collector vessel when the

level indicator marker (43) shows full - danger of overspill! Disposal of the developer and ﬁxer requires observance of all regional rules and regulations! In Germany and many other countries, x-ray chemicals must be disposed of separately as special waste: check local regulations.

13. Start-up and first use

The developer unit XR 24 Pro has 3 different settings for the processing time, and is factory set at the following values.

Intraoral ﬁlms 6 min (program INTRA)

Extraoral ﬁlms 4 min (program EXTRA)

Endodontal ﬁlms 3:15 min (program ENDO)

Please note: X-ray ﬁlms with such short processing times are not suitable for archiving.

-Developer / ﬁxer bath temperatures 28°C

-Dryer performance 30%

When using other ﬁlm types requiring different processing times and dryer performance the the values will need to be changed as appropriate. Refer to the ﬁlm list, section 15.7.

For a program overview refer to the section "Usage"

The unit must only be used in com-

pletely closed state - with all side panels and cover ﬁtted and closed

- before connecting to the mains power supply.

Every time the unit is switched on at the

power switch then program "INTRA" is started, i.e. after the unit is switched off there is an automatic reset to "INTRA".

Guidance on using the unit and the

display for the operator can be found in section "Usage", section 15.

A complete description of the service

operation can be found on the section covering Maintenance 19.6.

The developer unit must never be

operated when the roller set is not present!

Where the roller sets are not inserted then there is pressure being exerted vertically upwards on the developer and ﬁxer ﬂuids and could splash out.

Chemicals irritate eyes and skin and there is the danger of serious eye damage.

Without developer and ﬁxer roller sets there can

be no return of chemicals to the appropriate containers.

There is also the danger of the chemicals mixing.

The developer unit must never be operated

without ﬂuids (chemicals, water) as this can lead to the heating breaking down.
