3.3.7.3.2.4
Maintenance Control Panel Tests
The Maintenance Control Panel Test shall provide the Off-Line
maintenance capability for the DPS. Maintenance Control Panel Tests shall provide an example of
detailed operating procedures for the Maintenance Control Panel, test description for each subunit,
library of normal operation codes, test codes, and test point waveforms for the normal operation in
order to provide a functional check of each subunit. The goal of the MCP tests shall be to provide
sufficient documentation to enable a Maintenance Technician to analyze the problem and formulate his
own detailed detection and isolation procedures. The contractor shall provide a Maintenance Control
Panel test for each subunit (excluding power supplies and the Maintenance Control Panel Subunit) of
the DPS. (The MCP is used as a tool to test the Logic Unit proper, but has no self-test capability.)
The tests shall include Universal Keysets, Pilot Keyset, Ordnance Panel, TACCO Control Tray,
Sensor Control Tray, Armament/Ordnance Panel and Magnetic Tape Transport in addition to all logic
subunits except Power Supplies. The use of the peripheral equipments not listed herein may be used
as an aid to the technician for the purpose of monitoring outputs and stimulating inputs to each DPS
subunit as needed. The Maintenance Control Panel tests shall be included as part of the Organi-
zational Maintenance Instruction Manuals for each Logic Unit and shall be validated and approved
as such.
Test Point Requirement - Any test points required shall accom-
3.3.7.3.3
modate general purpose test equipment, i. e. , multimeter or oscilloscope probes. In the event test
points cannot accommodate standard probes, use of adapters will be permitted. These adapters are
to be provided with and secured to the unit.
Special Support Equipment (SSE) - There shall be no special
3.3.7.3.4
support equipment for support of the equipment except as expressly authorized by the procuring
activity.
Nomenclature and Nameplates - Nomenclature assignment and
3.3.8
nameplate approval for equipment identification shall be in accordance with Specification MIL-N-18307.
Standard Conditions - The following conditions shall be used to
3.3.9
establish normal performance characteristics under standard conditions and for making laboratory
bench tests.
Room ambient (25C 5C)
Temperature
Normal Ground
Altitude
None
Vibration
Room ambient up to 90% relative humidity
Humidity
115 l.0 VAC, 3 phase 400 Hz 1%
Input Power
Voltage
Service Conditions - The equipment shall operate satisfactorily
3.3.10
under any of the environmental service conditions or reasonable combination of these conditions as
specified in Specification MIL-E-5400 for Class 1AX equipment, except as modified herein.
Vibration - The equipment shall operate satisfactorily when
3.3.10.1
subjected to the vibration requirements of MIL-E-5400 Curve I from 5 to 32 Hz and 2 g from 32 to
500 Hz.
Attitude - The equipment shall operate satisfactorily in all
3.3.10.2
attitudes and orientations within 90 of its normal mounting orientation.
Fungus Treatment - Equipments shall be fungus-proofed by
3.3.10.3
selection of parts and materials that are non-nutrient for fungus, or the parts and materials shall be
so treated prior to their use in the equipment that over-all spraying of the equipment is not necessary.
