3.3.4 Continuity (loaded armed condition). The resistance measured
between the two solder terminals through the detonator with the rotor in the
armed position shall be 3.5 ohms 1.5 ohms. CAUTION - ANY CONTINUITY
MEASUREMENT WHICH SHALL PASS ELECTRICAL CURRENT THROUGH THE DETONATOR SHALL BE
LIMITED TO ONE MILLIAMPERE MAXIMUM.
3.3.6 Rotor reset capability. The rotor shall have the capability of
automatically resetting itself to the extreme safe position whenever the rota-
tional arming torque is removed after the rotor has traveled through an angle
of rotation of up to 35 degrees from its starting position.
3.3.6 Insulation resistance, armed position, unloaded. The resistance
measured between the ground and positive solder terminals of the switch shall
be not less than 30 megohms at 500 volts.
3.3.7 Power supply striker release time (Type I only). When tested on a
centrifuge the time between release of the setback weight and the release of
the power supply striker shall be between .35 second minimum arming time and
.40 second maximum. The device shall meet this requirement at any temperature
between minus 40 and plus 160 degrees F and any acceleration between 27 and
40 g.
3.3.8 Release pin release time (Type II only)
During the arming time
tests the time between release of the setback weight and the release of the
Release Pin shall be not less than 0.20 second or more than 0.85 second.
3.3.9 Setback weight return capability. The setback weight after being
bottomed to the base of the main frame by a force of 20 lbs, applied equally
to its two top surfaces and then released, shall return in a continuous motion
to the fully safe position of locking the rotor.
Neither the setback spring dwg. 11008392
3.3.10 Spring embrittlement.
nor the detent spring dwg. 11706267 shall break when extended to the point of
minimum permanent distortion.
3.3.11 Spring set. The setback spring dwg. 11008392, after being
subjected to a temperature of 175-180F at a compressed length of .750 inch
for 24 hours and then allowed to cool at ambient for 24 hours, shall return to
.015 inch of its original free length.
Dwg 11707051 (Type I) or 11830060 (Type II)
3.4 Power supply.
3.4.1 Type I only. The Power Supply shall meet all the applicable
requirements of MIL-P-60949.
3.4.2 Type II only (MIG).
3.4.2.1 Spring Force. The force of the MIG spring measured at 0.125 inch
compression shall be 6.5 pounds 1.00 pound.
