6、d be carried out by technically qualified service personnel only. Mains power is dangerous and can kill. Do not attempt to work on a linear or switched mode power supply if you are not suitably qualified to do so. Do not attempt to repair surface mount circuit assemblies unless you are suitably qual

7、ified and have the necessary facilities to do so. Replacement circuit assemblies can be ordered. Service facilities: Ensure a suitably sized work surface is available. Ensure this is clear of dirt, debris and obstructions which may damage the equipment surfaces. Ensure adequate lighting. Use the cor

8、rect tools for the job and ensure they are in good working order. Ensure all workshop safety requirements are adhered to. Service information: Check that you have all the information you need before starting the service job. Refer to the Allen & Heath web site or contact Allen & Heath technical supp

9、ort for details on the latest information. Full technical information can be downloaded from the web site Distributor Zone (password required). Mains power: Connect the equipment to mains power only of the type described in the user guide and marked on the rear panel. The power source must provide a

10、 good ground connection. Ensure you always use an isolation transformer when working on any mains power supply unit. Mains cord and fuse: Use the correct power cord as supplied with the equipment. Do not remove or tamper with the ground connection in the power cord. Heed the Important Mains Plug Wir

11、ing Instructions printed in the user guide if it is necessary to rewire the mains cord. Always replace the equipment mains fuse with the correct type and rating as described in the user guide and marked on the equipment panel. Opening the unit: Switch off and remove the mains power cord before openi

12、ng the equipment. Ensure all power supply covers and safety shields are in place before applying power with the unit open for diagnostic fault finding. Closing the unit: Before finishing, check the quality and accuracy of the service work carried out. Remove any dirt or debris as this may cause equi

13、pment failure in the future. Ensure all assemblies, harnesses and connectors are correctly aligned and plugged in. Ensure that jumper settings and control configurations are correctly set according to the requirements of the customer. Testing the unit: Before operating the equipment, read and adhere

14、 to the Important Safety Instructions printed in the user guide. Test that the service work has been successfully carried out. Shipping the unit: Use adequate packing such as the original packaging or purpose designed flight case if you need to ship the unit. To avoid injury to yourself or damage to

15、 the equipment take care when lifting, moving or carrying the equipment. Servicing Notes XONE VF-1 User maintenance: There are no user serviceable parts inside. Refer any service work to competent technical personnel only. Technology: The XONE VF-1 uses SMT (surface mount) PCB technology. In certain

16、 cases it may be better to replace a faulty assembly rather than try to fix it without the appropriate tools and training. The power supply is a built-in universal mains input, switched mode circuit which should be serviced by suitably qualified personnel only. Operation: The XONE VF-1 is an analogu

17、e filter unit. To ensure optimum performance and reliability it should be connected and operated as described in the user guide. Fault finding: Refer to the system block diagram and circuit drawings to follow through the signal path during fault diagnosis. Replace suspected faulty components only wi

18、th those specified by Allen & Heath. The use of lower grade alternatives may degrade the performance. 4 xonevf-1_ap6047_1.doc Contents Log Internal Layout Drawing.xonevf-1_layout_1.pdf Surface and Main Parts.xonevf-1_parts_1.pdf System Block Diagram . xonevf-1_blockdiagram_1.pdf Main PCB Assembly is
