MIL-A-81373(AS)
(2) DC Power +1OV, 0.5 amp
(3) DC Power -1OV, 0.1 amp
Degraded Performance - Degraded performance will be permitted for
3.3.10.1
voltage transients not exceeding 0.5 second during normal electric system operation.
Operation shall return to normal with no resulting damage to the equipment.
Performance - Unless otherwise specified, values set forth to establish
3.4
the requirements for satisfactory performance apply to performance under both standard
and extreme service conditions. When reduced performance under the extreme conditions
is acceptable, tolerances or values setting forth acceptable variations from the performance
under the standard conditions will be specified.
3.4.1
Operation - The number of ripple output fire pulses are limited to the
quantity selected by the pilot by the assembly.
Operational Requirements - The assembly shall meet the operational
3.4.2
requirements of 3.4.2.1 and 3.4.2.2 subject to the operating conditions shown on figure 1,
and to the following definition of terms:
(1) Application of a reset pulse (at terminal 3) shall mean momentary
closing of switch S2 .
(2) Application of a "'fire" pulse (at terminal A) shall mean momentary
or extended opening of switch S1.
(3) The logic "1" level shall be greater than +5 volts dc.
( 4 ) The logic "O" level shall be less than 0.5 volt dc.
(5) Selection of a given quantity (number of pulses) is accomplished by
setting the particular switch S3 through S13 associated with that
quantity to the +28-volt contact (see figure 1). All other switches
shall remain in the positions as shown.
Following the application of a reset pulse at terminal 3, the disable out-
3.4.2.1
put shall be at the logic "1" level, and shall remain at that level until the occurrence of the
condition specified in 3.4.2.2.
The disable output shall switch to the `0" level when the number of fire
3.4.2.2
pulses applied to terminal A is equal to the particular quantity selected, and shall remain
at that level until the reset condition of 3.4.2.1 is implemented. Switchover to the W"
level shall occur at the trailing edge of the last such fire pulse being applied.
Detail Requirements - Quantity select assembly 65A132F9 shall meet
3.5
.
the following requirements.
