Procedure

When PF-P27 or PF-P28 is installed

  1. Check the connector between M1/3-PCCB/3 CN4 for proper connection and correct as necessary.
  2. Check the connector between PCCB/3 CN1-relay CN2PC-PCCB/2 CN2 for proper connection and correct as necessary.
  3. Check the connector between PCCB/2 CN1-relay CN24-BASEB CN21E for proper connection and correct as necessary.
  4. Check the connector of M1/3 for proper drive coupling and correct as necessary.
  5. Check CPUB for proper installation and correct as necessary.
  6. M1/3 load check
    • Check code: 28
    • Multi code: 3, 4
    • Control signal: PCCB/3 CN4-1 to 7
    • Location of electrical component: 19-P
  7. Replace M1/3.
  8. PCCB/3 F1 and F2 conduction check
  9. Replace PCCB/3.
  10. Replace CPUB.
  11. Replace BASEB.

When PC-419 or PC-420 is installed
