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.

9. Installation

27

9.1 Connecting water supply

• Check firstly that clear, clean water is issueing from the water tap (27) When installing for the first time, let the water flow thoroughly first!
• Because of the great differences in the
31
regional quality of water, a fine filter (32) must first be installed between the water tap (27)
32
and water hose (34).
33 34
7
35
34
The fine filter (32) protects the flow
regulator of the water intake valve of the appliance from impurities
• Close the water tap (27)
• Connect an elbow piece, 90° (33), to the water tap (27), then fine filter (32) (arrow in direction of flow) and insert double nipple piece (31)
Check whether the coarse filter (34a)
and both seals (34b) are present in the threaded connection piece of the water hose (34).
• Connect the water hose (34) to the water inflow connection (35) of the appliance (threaded connection including coarse filter) and fix to the double nipple piece (31).

10
11
max. 3 cm
When laying the waste water
conections please be sure to check the following:
- Avoid hoses from sagging!
- Avoid constriction or reduction of hoses!
• Coat the ends of the hoses on the outside with UHU-Plast
• Fix the screw socket (37) onto the hose and onto the siphon trap (25) using hose clamp (38)
• Secure the waste water hose with hose clamp, screw and dowel.
37 38
9.3 Connection of developer and
25
fixer waste hoses
• Set the 10l-collecters (39) for developer (black level indicator marker) and fixer (red level indicator marker) under the appliance so that they are clearly visible but free from any possible spillage or knocking
• Lay the hoses (40) with continuous fall
40
• Cut the hoses to the correct length.
41
• Lead the hose for developer (black markings) through the black lid (41).
• Securely screw the lid (41) onto the collecter (39) for developer
• Secure the hose for fixer (red markings) in the same way to the collecter for fixer
39
Empty the collecters when they
reach the level indicator marker (43) - danger of overflow! When disposing of developer and fixer observe regional rules and regulations! In Germany, and in several other countries, x-ray chemicals must be disposed of as special waste.
