Trouble typeC1140: Alignment motor/Rr drive malfunction (When FS-539 or FS-539SD is installed)
RankB
Trouble detection condition-The alignment plate home sensor/Rr (PS13) is not turned OFF (unblocked) after the set period of time has elapsed after the plate drive starts from the home position.

-The alignment plate home sensor/Rr (PS13) is not turned ON (blocked) after the set period of time has elapsed while the alignment motor/Rr (M8) is energized when the plate returned to the home position.

-The plate does not reach the specified position within the set period of time.
Trouble isolation–
Relevant electrical parts-Alignment motor/Rr (M8)
-Alignment plate home sensor/Rr (PS13)
-FS control board (FSCB)

Procedure

  1. Check the connector between M8-relay CN19-FSCB J12 for proper connection and correct as necessary.
  2. Check the connector of M8 for proper drive coupling and correct as necessary.
  3. Check the connector between PS13-FSCB J9 for proper connection and correct as necessary.
  4. PS13 I/O check, sensor check
    • Control signal: FSCB J9<B>-12 (ON)
    • Location of electrical component: FS-539/FS-539SD 10-C
  5. M8 operation check
    • Control signal: FSCB J12-13 to 16
    • Location of electrical component: FS-539/FS-539SD 7-C
  6. Replace M8. (Part# A3EPPP5500)
  7. Replace FSCB. (Part# AAR4PP8201)

RankB
Trouble detection condition-The alignment plate home sensor/Rr (PS6) is not turned OFF (unblocked) after the set period of time has elapsed after the plate drive starts from the home position.

-The alignment plate home sensor/Rr (PS6) is not turned ON (blocked) after the set period of time has elapsed while the alignment motor/Rr (M13) is energized when the plate returned to the home position.

-The plate does not reach the specified position within the set period of time.
Trouble isolation–
Relevant electrical parts-Alignment motor/Rr (M13)
-Alignment plate home sensor/Rr (PS6)
-FS control board (FSCB)

Procedure

  1. Check the connector between M13-relay CN3-FSCB J21 for proper connection and correct as necessary.
  2. Check the connector of M13 for proper drive coupling and correct as necessary.
  3. Check the connector between PS6-relay CN4-relay CN3-FSCB J21 for proper connection and correct as necessary.
  4. PS6 I/O check, sensor check
    • Control signal: FSCB J21-10 (ON)
    • Location of electrical component: FS-540/FS-540SD 4-D
  5. M13 operation check
    • Control signal: FSCB J21-1 to 4
    • Location of electrical component: FS-540/FS-540SD 4-D
  6. Replace M13. (Part# A87HPPAD00)
  7. Replace FSCB. (Part# AAR5PPD401)
