Mains power is dangerous and can kill. Do not attempt to work on a linear or swi

6、tched 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 qualified and have the necessary facilities to do so. Replacement circuit assemblies can be ordered. Service facilities: Ensure a suitably sized work

7、surface is available. Ensure this is clear of dirt, debris and obstructions which may damage the equipment surfaces. Ensure adequate lighting. Use the correct tools for the job and ensure they are in good working order. Ensure all workshop safety requirements are adhered to. Service information: Che

8、ck 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 support for details on the latest information. Full technical information can be downloaded from the web site Distributor Zone (password required). Ma

9、ins 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 good ground connection. Ensure you always use an isolation transformer when working on any mains power supply unit. Mains cord and fuse: Use the

10、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 Wiring Instructions printed in the user guide if it is necessary to rewire the mains cord. Always replace the equipment mains fuse with the correct t

11、ype 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 opening the equipment. Ensure all power supply covers and safety shields are in place before applying power with the unit open for diagnostic fault fin

12、ding. 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 equipment failure in the future. Ensure all assemblies, harnesses and connectors are correctly aligned and plugged in. Ensure that jumper settings and

13、 control configurations are correctly set according to the requirements of the customer. Testing the unit: Before operating the equipment, read and adhere to the Important Safety Instructions printed in the user guide. Test that the service work has been successfully carried out. Shipping the unit:

14、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 the equipment take care when lifting, moving or carrying the equipment. Servicing Notes PA-CP User maintenance: There are no user serviceable par

15、ts inside. It should not be necessary for the user to remove the cover or access internal parts. Technology: The PA-CP uses conventional thru-hole and SMT (surface mount) PCB technology. It has a built-in linear regulated power supply which should be serviced by suitably qualified personnel only. Op

16、eration: To test the console make sure it is connected as described in the user guide. Check that the voltage setting marked on the rear panel is correct for the local mains supply. Fault finding: For effective fault diagnosis trace the signal flow through the circuit path. Refer to the system block
