Servicing Precautions – General Notes
Service personnel: Service work should 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 qualified 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 correct 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 support 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 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 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 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 opening 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 equipment 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 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 the equipment
take care when lifting, moving or carrying the equipment.
Servicing Notes – PA-CP
User maintenance: There are no user serviceable parts 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.
Operation: 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 diagram. Replacement circuit assemblies are available from Allen &
Heath.
