The higher the kV value is the more penetration power the radiation has. The mA value adjust the amount of the radiation. The higher the mA value is the more radiation (photon flow) is produced by the X-ray source. 4. WASHING INSTRUCTIONS Never wash the system when it is running! Make sure Main power is switched off and the power cable is disconnected before starting the wash! 4.1 Opening and washing of system port Washing of system port: 1. Open the front door. 2. Dismount all non-fixed parts. 7 Rev Date Issued Version A 2014-10-20 DSY10003A 1. Take the conveyor out after dismounting cable connections. 2. Lead curtain cassettes can be pulled out. Pay attention to the safety magnets at inner curtains! 3. Wash the system port regularly with moistened cloth. If the inside of the system gets too dirty, the X-ray performance may decrease or lead to damages of the conveyor belt, which again may cause false rejections. NOTE! Protect all non-waterproof parts before washing direct water! 4.2 Removing the conveyor belt system 1. Switch off the system using the main power switch. 2. Disconnect cables between the system and the conveyor. 3. Slightly raise the conveyor and lift it out of the system. Main power switch Cable connections 4.3 Removing the curtain cassette The four curtain cassettes can be removed easily by lifting them up slightly and pulling them out. The inner cassettes are equipped with safety contact magnets. The X-ray can’t be switched on if they are not in correct positions. 8 Rev Date Issued Version A 2014-10-20 DSY10003A Lead curtain cassettes Safety contacts 4.4 Protecting the non waterproof parts 1. Place a hood over the screen of the system before washing. The display is not waterproof! 2. Wet wipes are recommended when washing the middle section of the system. Using direct water is normally not necessary. 3. Avoid spraying water directly to the bottom panels, where fans and different connectors are located. 9 Rev Date Issued Version A 2014-10-20 DSY10003A 4.5 After washing: secure functionality • After cleaning the system and its • Make sure the curtain cassette is mounted components, mount all parts according to correct and the curtain cassettes with instructions to their original form and place. safety contacts are on the inside. • Make sure all cables are connected properly • Make sure you have needed training and and onto right places. permission to use system before switching it back. 5. MAINTENANCE 5.1 Warnings Radiation hazard Before using the X-ray inspection system, ensure Never put any parts of the body inside the system that the protective lead curtains are in place and when the X-ray is on! the system is entirely fit for use! 5.2 Parts 5.2.1 X-ray generator The maximum power of X-ray tube is limited to Picture of the 200W.
