Shielding shall be provided to protect sensitive, Iow-power level circuits
3.3.1.30 Shielding.
against the electromagnetic interference effects of conducted or radiated radio frequency energy
whether internally or externally generated. Shielding shall not prevent replacement of defective
wafers.
3.3.1.31 Plug-in modules.
To prevent wafer destruction caused by inadvertent dislocation,
each male module connector and corresponding receptacle shall have a positive safety device to
physically prevent insertion of a module into the wrong receptacle.
3.3.1.32 Drawing
identification.
All micro electronic modules, wafers, or other units
identifiable as a functional entity shall be identified by reference designator and nomenclature on
all corresponding drawings used for assembly, test, maintenance, repair, or training purposes. All
critical electrical performance characteristics or parameters necessary for normal operation and test
or repair shall be identified. Where possible, circuit functions shall be shown by discrete electrical
component equivalents.
Each trainer, independently operable
3.3.1.33 Hydraulic and pneumatic power hoses.
trainer panel, or panel group which requires the use of hydraulic or pneumatic power shall be
provided with twenty-five (25) foot flexible hoses, as required, for connecting the trainer panels to
the facility or trainer hydraulic or pneumatic power supply system or for trainer panel interconnect,
as applicable. Appropriate female quick disconnect fittings, with dust covers, shall be installed in
each end of each hydraulic or pneumatic hose to provide for mating with the male quick disconnect
fittings on the trainer panels and the facility hydraulic or pneumatic power supply system. When
pressure and volume flow is the same, all hydraulic pressure hoses shall be interchangeable and all
hydraulic return flow hoses shall be interchangeable; however, hydraulic pressure hoses and return
flow hoses shall not be interchangeable with each other. When pneumatic pressure and volume flow
is the same ail pneumatic hoses shall be interchangeable with each other.
Individual trainer panels requiring
3.3.1.34 Hydraulic and pneumatic in interconnection.
external hydraulic or pneumatic power shall have hydraulic/pneumatic manifolds with appropriate
male hydraulic quick disconnects or pneumatic fittings installed on the rear center of the panel, and
shall be capable of conducting hydraulic or pneumatic power through the manifold connections to
two (2) or more related trainer panels, with the individual trainer panel power either "OFF" or
"ON" when connected in series from a single hydraulic or pneumatic power source. Each
maintenance trainer and individual trainer panel which is not part of a paneI group shall be capable
of independent operation when connected to the power supply, and shall contain an appropriate
control panel for this purpose. Connectors shall be provided at all disassembly points on trainers
requiring disassembly for shipment.
