7. Functional description XR 24 NDT

The display panel will light up once the main power switch has been pressed .The warming-up phase for the developer and
fixer baths will now begin. The waiting time until the correct temperature is reached will be displayed: "WAITING TIME . . MIN" (display blinks). The unit will not unit during this warming up period.
The bath circulation process runs in parallel to the bath heating. The circulation precess involves the rotatory pump (14) transporting the chemicals from the developer and fixer baths (tank volume of 5 liters each) to the lifting bath (22).
Once the set temperature has been reached the display lights "MACHINE FREE", i. e. the unit is on "Standby" As soon as the temperature falls by more than
0.5 °C below the set temperature, the process
heater and the rotary pump (14) switch on again.
Insertion of a film causes the film feed flap (2) to open and the display blinks: "MACHINE OPERATING" At the same time a signal is activated to lower the lifting bath (22) and the water intake valve (15) opens; the dryer heater (10), drive motor (12) and rotatory pump (14) (for developer and fixer bath circulation) start. The processing time can be checked using the RPM controller (12a). Lifting and lowering of the lifting bath is controlled by the rotation of the disc (driven via the lift motor (20)) and is monitored by the infrared light barrier (19a).
(mind.2 s)
If the waste water drainage becomes blocked, a level indicator sensor (13) activates an audible signal and the water intake valve (15) closes and the flow of water is interrupted. After complete insertion of a film the film feed flap (2) closes. As soon as the blinking display "MACHINE IN OPERATION" is extinguished a new film or 6 intraoral films alongside each other can be inserted. If no further films are inserted after the film process cycle (audible signal) then the lifting bath (22) rises (Stand By Position) "MACHINE FREE". The drive motor (12), water intake valve (15) and dryer heater (10) are switched off. In the Stand By Position the developer and fixer roller sets (5) are completely submerged in the chemicals. This means that the build up of deposits on the rollers can largely be avoided.

When the lifting bath (22) is lowered the film passes between the rollers through the developer and fixer baths, then through the rinsing and the drying zones (8) at the set processing time.
During film development water is fed along the water inflow (7) into the rinse zone. The water flows out to the waste water system. There is a continuous flow of water at a rate of ca. 2 l/min, at a pressure of 2 bar.

13. Commissioning and first set up

The developer unit XR 24 NDT has 3processing time alternatives, and is factory set as follows:
10:00 min - Program REG. GRAIN 8:00 min - Program MTID. GRAIN 5:30 min - Program FINE GRAIN
Please note: X-ray films are not suitable for archiving at this processing time. When using film types which require a different processing time, set the values according to
EN
the type of film being used.
- developer / fixer bath temperature 28°C
- dryer performance 30%
Films should emerge dry from the unit. The dryer performance should be set according to film type.
Program overview, see section Usage
The unit may only be operated when
it is closed - with sides and cover in position - and connected to the mains supply.
Every time the unit is switched on at the
main power switch the program "REG. GRAIN" is automatically started, i.e. after switching off there is an automatic default selection of "REG. GRAIN"
Instructions concerning the operation
and display for the operator can be found in section "USAGE", section 15.
A complete plan for service operation
can be found under Maintenance, section 19.6.
Before developing the first film
the lifting tank of the developer and fixer baths must be filled to the overflow level, otherwise the film development quality may be impaired.
Always use cold water when making
up the chemicals.
The developer unit must never be
operated without its roller sets!
Without the roller sets it is possible that the developer and fixer fluids will be placed under pressure and will splash vertically upwards out of the developer unit.
Chemicals attack eyes and skin and
there is the possibility of severe injury to the eyes.
Without the developer and fixer roller sets there can be no circulation of chemicals in the baths.
There is the danger of mixing of
chemicals.
Never operate the developer unit
without fluids (chemicals, water), as this can lead to the heating controller breaking down.

Service Technician can set them, however, to your individual requirements.
REG. GRAIN - Process time: t=10min
- bath-temperature: T=28 °C
- dryer performance: 30%
REG. GRAIN - Process time: t=8min
- bath-temperature: T=28 °C
- dryer performance: 30%
REG. GRAIN - Process time: t=5min
- bath-temperature: T=28 °C
- dryer performance: 30%
Films should emerge dry from the unit. The dryer performance should be set according to film type.
Every time the unit is switched on at the
main power switch the program "MID. GRAIN", is automatically started, i.e. after switching off there is an automatic default selection of "MID. GRAIN"

15. Operation

Before operation please note the following points:
The developer unit must never be
operated without its roller sets!
Without the roller sets it is possible that the developer and fixer fluids will be placed under pressure and will splash vertically upwards out of the developer unit.
Chemicals attack eyes and skin and
there is the possibility of severe injury to the eyes.
Without the developer and fixer roller sets there can be no circulation of chemicals in the baths.
There is the danger of mixing of
chemicals.
Never operate the developer unit
without fluids (chemicals, water), as this can lead to the heating controller breaking down. Regulate the heating.
The unit should be switched on every
day in order to maintain constant image quality.
Ensure that the ambient temperature of the environment does not exceed that of the developer bath!
Standby-Modus
Once the film exits the unit the Standby-Mode is activated. In Standby-Mode the unit is still operational and simply awaits the next insertion of a film. Before inserting a film check the program selection!

immediately rinse thoroughly with water and consult a doctor as soon as possible.
Clean your hands thoroughly under
running water after finishing.
Please also refer to our special safety brochure which you can find on the internet at: http://www.duerr-ndt.de or order it direct from Dürr NDT.
Usage of chemicals from third party
suppliers
When using chemicals from third party suppliers please refer to the manufacturer's instructions when making
up the chemicals. All developer units which have already been operated using chemicals from third party suppliers can be converted to DürrXR24NDT chemicals at any time. Please note that the baths should be cleaned thoroughly before changing chemical source (refer to the manufacturer's instructions)
Usage of DürrXR24NDT chemicals
Dürr NDT developer and fixer chemicals
are based largely on natural ingredients.
Components such as Hydroquinol or
aldehyde are avoided as far as possible. This reduces the accumulation of dirt in the unit and thereby also reduces cleaning.
