TM 55-1510-222-10 23.  On  test  set,  observe  DISPENSER  COMPLETE annunciator (green) is illuminated and then perform the following operations: a. Rotate TEST SEQUENCE switch counterclockwise  to  SYS  NOT  RESET  position.    SYS NOT RESET annunciator (amber) will illuminate. b. Press     and     release     MANUAL     SYSTEM RESET switch.  SYS NOT RESET annunciator (amber) will extinguish. NOTE When  the  MANUAL  SYSTEM  RESET switch  is  pressed  and  released,  and 28  volts  DC  power  is  being  applied, the    sequencer    switch    inside    the dispenser   assembly   resets,   making an audible sound as it rotates.  If the sequencer switch has been previously reset or if the switch is in position  12  or  24,  there  will  be  no such sound. c. Rotate TEST SEQUENCE switch counterclockwise   to   STRAY   VOLT   position.      STRAY VOLTAGE annunciator (red) should not illuminate. d. Rotate TEST SEQUENCE switch counterclockwise to START/HOME position. NOTE When  turning  the  TEST  SEQUENCE switch    to    the    OFF    position,    the DISPENSER COMPLETE annunciator will extinguish, the STRAY VOLTAGE annunciator  will  illuminate  and  then will extinguish when the OFF position is reached. 24.  Install safety pins. 25.  Disconnect test set power cable. 26.  Remove M-91 test set from dispenser assembly and restore in carrying case along with the power cable and hexagonal wrench. 27.  On    DCP,    set    ARM-SAFE    switch    to    SAFE position. 28.  On DCP, reset CHAFF counter to 30. 29.  Disconnect    aircraft    power    by    pulling    the    5- ampere   Ml30   circuit   breaker   located   on   the   mission control panel (fig.  4-1). 30.  Proceed    immediately    to    ammunition    loading procedures. 4-5.AMMUNITION. a. Ammunition Loading Procedure. WARNING Only one shipping container is to be opened   at   a   time.      If   a   shipping container has been opened and only partially emptied, the remaining contents    will    be    secured    in    the container with an appropriate type of packaging material or filler to adequately    prevent    jostling.        All munitions in storage must be in their original shipping containers. 1. Place payload module assembly on work bench in   approved   safe   area   so   that   the   retaining   plate   is facing up. 2. Remove    retaining    plate    by    unscrewing    two retaining bolts. 3. Insert  one  flare  (or  chaff)  at  a  time  into  each chamber of payload module. 4. Remove   plastic   dust   cap   from   each   chaff   or flare. CAUTION Prior    to    insertion    of    an    impulse cartridge, be sure there is a preformed packing in the flare cartridge.      (There   will   be   no   pre- formed  packing  in  chaff  cartridges.) Reinstall any preformed packing that is inadvertently removed with dustcap.      The   loading   of   impulse cartridges  into  a  flare  or  chaff  shall be accomplished one at a time. 5. Insert  one  impulse  cartridge  into  each  flare  (or chaff). 6. Install  retainer  plate  assembly  by  screwing  the two retainer bolts into payload module. WARNING The system must have been tested to ensure that there is no stray voltage and     all     aircraft     power     must     be removed   from   the   system   prior   to loading the payload module. 7. On  the  dispenser  control  panel,  ensure  ARM- SAFE switch is in SAFE position. 4-8
