    Chapter 1 – Introduction Welcome to the user manual for the SPECS CCX 70. This controls and monitors the water cool- ing for SPECS X-ray sources. This chapter explains briefly how to use the manual and points you toward further sources of information.

  • Page 6: Safety

    After switching off the power units, wait a minimum of 3 minutes before making dis- connections or opening power supplies or the X-ray source protection cover. Ÿ In the event of a water leak in the CCX 70, make sure that all parts are dry before attempt- ing to operate the source again. Ÿ...

    SPECS recommends a water chiller to supply water to both cooling circuits on the source. Fig- ure 1 shows the connection scheme for the water cooling. The Chiller output on the CCX 70 supplies a +24 VDC signal when the cooling is activated. This switches the power supply to the water chiller.

    Clean tap water is recommended for the cooling water. If you have doubts about the quality of your mains water supply, you should use distilled (or deionized) water and add bottled mineral water until the water current reaches the normal range (2…10 mA). CCX 70 V1.1 | 29 April 2016...

    Figure 2: Operation of X-ray source For stable operation, the water current should be in the range 2…10 mA. You can monitor the water current in the Chiller menu of the UXC 1000. CCX 70 V1.1 | 29 April 2016...
  • Page 18 High water current can also be caused by contaminants in the cooling water. In this case, per- form some cleaning cycles with tap water to wash the cooler and the water lines, then refill the cooler with deionized or distilled water. CCX 70 V1.1 | 29 April 2016...

  • Page 19: Chapter 4 - Operation

    Chapter 4 – Operation The CCX 70 is controlled by the UXC 1000. In addition to switching the water cooling on and off, the UXC 1000 can display the status of the CCX 70 and allows you to set parameters such as the water flow and temperature limits.

    Software SpecsLab Prodigy has facilities for controlling an X-ray source via the UXC 1000. You can view the properties of the CCX 70 in the device control for the UXC 1000 as well as setting limits for the cooling water.
  • Page 21 Figure 4: Viewing the cooling water parameters in SpecsLab Prodigy Limits tab allows you to change the settings for the cooling water. Please see the UXC 1000 manual as well as the SpecsLab Prodigy Online Help for more information. CCX 70 V1.1 | 29 April 2016...

    Check water. high! (2203)" Table 1: UXC 1000 error messages relating to the CCX 70 Most of these problems are related to the interlock conditions being satisfied, or to the correct flow of water in the circuits, as described in more detail in the following sections.

  • Page 24: Water Interlock Problems

    Ÿ Examine the water hoses between the CCX 70 and the source. Make sure there are no kinks or loose connections. Also check the temperature of the water. This should be ~20 °C. If it is not within the limits set in the UXC 1000, check your water supply or chiller unit.
  • Page 25 2. Fit the bypass hose to the anode connectors in order to complete the circuit, as indicated in the picture below. 3. Switch on the water cooling circuit and check the water flow. CCX 70 V1.1 | 29 April 2016...

    Over time, small particles will appear in the water supply due to electrochemical reactions. The CCX 70 contains internal filters as well as an external filter to the water supply. Over time, con- taminants will build up on these filters and connections. Clean these parts occasionally to ensure adequate water flow and to prevent contaminants from damaging the source.

    2. Remove the protection cap from the source (see "Fitting the Protection Cap" on page 7) 3. Remove the quick hose connector. 4. Clean the hose connectors and anode tubes on the source using tissues or cotton wool tips and water. CCX 70 V1.1 | 29 April 2016...

  • Page 29: Cleaning The External Filter

    If you remove the filter from the hose, observe the flow direction when reconnecting. To clean the external filter: 1. Switch off the water cooling supply. 2. Unscrew the cover on the blue filter on the water input line. 3. Remove the white filter. CCX 70 V1.1 | 29 April 2016...

    Very long working periods or poor water quality can cause a build up of contamination in the cooling circuit. These deposits are visible in the tubes inside the CCX 70. If you have a closed circuit water chiller, you can clean the whole circuit by pumping a citric acid solution through the system.
  • Page 31 Use a saturated solution of citric acid (~750 g/l of water). Ÿ Warm the water with a thermostat up to a temperature of ~50–60 ºC. Ÿ Run the citric acid solution through the source for up to 24 hours. CCX 70 V1.1 | 29 April 2016...
