(b) The input pin shall be continuously monitored for a stray
energy accept/reject decision in accordance with the limits of
table V. A reject decision shall be latched and displayed on
STRAY ENERGY GO/NO-GO lamps until both an acceptable input is
monitored and the latch has been reset by the PRESS TO READ
DVM/RESET pushbutton or changing the position of the FUNCTION
SELECT switch.
(8) Power changeover, W1, P2-19.
(a) A load shall be applied from ground to pin W1, P2-19 as
specified in 3.4.5.2.a.(7)(a).
(b) The input shall be monitored as specified in 3.4.5.2.a.(7)(b).
(9) Motor fire squib, W1, aft striker contact.
(a) A load shall be applied from ground to the aft striker block
electrical contact as specified in 3.4.5.2.a.(7)(a).
(b) The input shall be monitored as specified in 3.4.5.2.a.(7)(b).
(10) Missile audio, W1, P2-15.
(a) The output shall be an ac signal of frequency F2
300 Hz,
in accordance with Drawing 2412395. Output amplitude shall be
selectable by the test set AUDIO switch: OFF equal to not
greater than 0.1 volt ac; LO equal to 1.00 0.25 volt
ac; and HI equal to 3.00
0.25 volts ac. output
impedance shall be not greater than 400 ohms.
(b) Load impedance shall be not less than 1,000 ohms.
(c) Capacitance to ground shall be not greater than 0,04
b.
FUNCTION SELECT test two.
(1) Launch latch, W1, P2-3,
(a) A 30.3 + 5 percent ohms resistive load shall be applied
between-ground and the input pin (W1, P2-3) for 20
milliseconds out of each second.
(b) The input pin shall be monitored for correct voltage in
accordance with the accept/reject limits specified in table
III. The accept/reject decision shall be updated at a one
Hertz rate at a point 14 milliseconds after the application of
the 20 millisecond resistive load pulse.
(c) Capacitance from pin W1, P2-3 to ground shall be not greater
than 0.3
(2) Power changeover, W1, P2-19.
