TM 1-1510-223-10 6. Remove    safety    pins    from    on    right equipment   rack   aft   of   copilot's   seat, and on top skin of right wing. 7. Provide aircraft power to M-130 system by resetting the M-130 POWER circuit breaker. 8. ASE mode select switch on multifunction display (MFD, fig.  4-2) - Depress to call up ASE control page. 9. L3 line selector switch - Depress to set DISPENSER to ARM. 10. R5 line selector switch - Depress to call up ASE SETUP page. b. Flare Dispenser System Test Procedure. 1. ASE mode selector switch - Depress to return to ASE control page. 2. Reinstall   safety   pins   one   at   a   time. PWR FAIL shall appear below DISPENSER on MFD. 3. Remove safety pins and verify DISPENSER is set to ARM on MFD. NOTE When    the    test    set    is    installed    on    the dispenser assembly and 28 volts DC aircraft power   has   been   applied,   the   sequencer switch  inside  of  dispenser  assembly  resets, making    an    audible    sound    as    it    rotates. There     will     be     no     such     sound     if     the sequencer switch has been previously reset or if switch is in position 12 or 24. On    test    set,    TS    PWR    ON    annunciator (clear)  illuminates  and  remains  illuminated throughout  the  test  sequence  until  aircraft power to test set (via test set power cable) is disconnected or shut off. 4. Perform the following operations on the M-91 test set. a. Press    to    test    remaining    three annunciators    on    test    set    Each annunciator will illuminate. NOTE Replace    any    annunciator    that    does    not illuminate   when   pressed.      If   none   of   the indicating    annunciators    illuminate,    return test set to AVUM (aviation unit maintenance). b. Rotate  TEST  SEQUENCE  switch clockwise     to     the     TS     RESET position.  No visual indication will occur. c. Rotate  TEST  SEQUENCE  switch clockwise    to    SV    SELF    TEST position. STRAY VOLTAGE annunciator (red) will illuminate. d. Rotate  TEST  SEQUENCE  switch clockwise  to  TS  RESET  position. STRAY     VOLTAGE     annunciator (red) will extinguish. e. Rotate  TEST  SEQUENCE  switch clockwise to STRAY VOLT position. STRAY VOLTAGE annunciator (red) should not illuminate. f. Rotate  TEST  SEQUENCE  switch clockwise   to   SYS   NOT   RESET position.          SYS     NOT     RESET annunciator   (amber)   should   not illuminate. If annunciator illuminates,     press     and     release MANUAL SYSTEM RESET switch    and    SYS    NOT    RESET annunciator should extinguish. NOTE When     the     MANUAL     SYSTEM     RESET switch is pressed and released, and 28 volts DC power has been 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. g. Rotate  TEST  SEQUENCE  switch clockwise  to  next  position,  DISP COMP. 5. Press either FLARE DISPENSE switch once.  For each depression the FLARE counter  on  DCP  should  count  down  in groups of three. 6. On  MFD,  depress  L5  repeatedly  until text    reads    RIPPLE    FIRE    ARMED. Within  7  seconds  ,  depress  a  FLARE DISPENSE switch.  Flare counter shall count   down   to   00   and   ALL   FLARES EXPENDED    shall    be    displayed    on MFD.    DISPENSE  COMPLETE  lamp (green) on test set shall be illuminated. NOTE DISPENSER    COMP    lamp    may    fail    to illuminate  during  the  previous  step  due  to improper connection between the base plate and  breech  plate.    If  this  happens,  remove and   reinstall   base   plate   to   ensure   proper connection  and  repeat  FLARE  DISPENSE tests.    If  this  still  does  not  result  in  proper operation,  verify  the  C-F  selector  switch  is in the F position. 7. Perform the following operations on the M-91 test set. a. Rotate  TEST  SEQUENCE  switch counter-clockwise    to    SYS    NOT RESET position. 4-6
