3.5.5.3 Circuit breaker.
3.5.5.3.1 Breaker open. - With the motor at standard temperature,
with 28 plus or minus 0.5 volts applied, the two indexes sepearated by at
least 200 meters, the output shaft for the ballistics drive locked
(immovable), the circuit breaker shall open in 90 seconds or less.
3.5.5.3.2 Breaker closed. - At standard ambient with the load as
specified in paragraph 3.5.2 applied to the output shaft for the ballistics
drive, the computer APDS-T, M392 Cam, the input shaft shall be oscillated
for a period of 45 seconds over a spread of 1000 meters, plus or minus 100
meters between ranges of 1200 to 2800 meters, at a rate of 4 to 4.5 re-
volutions per second, during which time the circuit breaker shall not open.
3.5.5.4 Hand crank and input shaft travel.
3.5.5.4.1 Hand crank.- The rotation of the superelevation hand crank
within the limits of its stops shall cover the excursion from minus 1.5
roils, plus or minus 0.1 mil, to plus 98.5 mils , plus or minus 0.5 mil, as
indicated on the superelevation counter when the range correction knob is
set at zero.
3.5.5.4.2 Input shaft.- The range input shaft shall rotate through
an excursion of 24.0 revolutions plus 0.1 revolution and shall cover the
range from 480 to 4575 meters within this excursion, as measured from the
1200 meter checkpoint of the input shaft.
3.5.6 Superelevation cams.- The cams shall be placed in the ballistics
computer in the following sequence starting with the HEAT-T, M456 and fol-
lowing with APDS-T, M392, HEP-T, M393 and ADERS-T followed by two spacers.
The computer shall be shipped with the same cams with which it qualified.
3.6 Electrical check.
3.6.1 Insulation breakdown. - Insulation breakdown shall be in accord-
ance with MIL-F-13926 except that breakdown voltage of 500 volts RMS shail
be substituted for 750 volts RMS.
