TM 5-6115-593-12 TO 35C2-3-463-1 a.   If   motor   operator   indicates   ON   (CLOSED), supply  power  to  off  leads  (brown  and  white) and check for proper sequencing as follows: 1.   Motor runs-Breaker cycles OFF (OPEN) as shown by indicator, sequence is proper. 2.   Motor  runs-Breaker  not  cycled  to  OFF (OPEN)     per     motor     indicator.          To engage   drive,   electrically   cycle   motor operator   to   ON   (CLOSED),   and   then OFF   (OPEN).   Drive   is   engaged   and breaker  will  be  turned  OFF  per  motor operator indicator.  Sequence is proper. 3.   Motor does not run - Sequence is out of order,   switch   supply   power   to   motor operator  ON  .leads.    Motor  will  run  to ON   position   and   stop.      Again   switch supply   power   to   motor   operator   OFF leads.  Motor  operator  will  run  to  OFF position   and   stop.      Breaker   will   be turned OFF per motor operator indicator. Sequence is proper. b.   If    motor    operator    indicates    OFF    (OPEN), supply power to ON (CLOSED) leads (yellow and  white)  and  check  for  proper  sequencing as follows: 1.   Motor runs-Breaker cycles ON as shown    by    motor    operator    indicator. Sequence is proper. 2.   Motor   runs-Breaker   not   cycled   to   ON per  motor  operator  indicator.  Drive  is not engaged. To engage drive electrically,    cycle    motor    operator    to OFF and then to ON.  Drive is engaged and   breaker   will   be   turned   ON   per motor  operator  indicator.  Sequence  is proper. 3.   Motor does not run - Sequence is out of order.    Switch  supply  power  to  motor operator  OFF  leads.    Motor  will  run  to OFF  position  and  stop.    Again  switch supply   power   to   motor   operator   ON leads.    Motor  runs,  breaker  cycles  ON as  shown  by  motor  operator  indicator. Sequence is proper. NOTE Due    to    the    switching    arrangement,    the motor  operator  must  run  to  the  limit  of  its travel  in  one  direction  before  it  will  run  in the   opposite   direction.      However,   it   will always run in one direction or the other.  If motor operator will run in neither direction, problems other than sequence exist. (3)   Replace    operator    arm    as    shown    in figure 4-15. 4-25.  PLATE AND SLEEVE ASSEMBLY. Replace the plate and sleeve assembly (7, figure 4-12) as follows: a.   Removal. Remove plate and sleeve assembly (7) from enclosure (99) by removing eight screws (6).  Referring to figure 4-16,  sleeves  may  be  removed  by  removing four  screws  (1)  and  four  nuts  (2)  attaching retainer  plate  (3).  Remove  bushing  (4)  and sleeve (5). b.   Installation.  Install plate and sleeve assembly (7, figure 4-12) onto enclosure (99) with eight screws   (6).      Replace   sleeves   by   installing sleeve  (5,  figure  4-16)  with  bushing  (4)  into plate hole.  Fasten with retainer plate (3), four screws (1), and four nuts (2). 4-26.  WEATHER STRIPPING AND SEALS. a.   Inspection.        Inspect    weather    stripping    (5, figure  4-12)  and  door  seal  (98)  for  signs  of excessive wear, rot, or damage. 4-48
