These are possible resolutions for the issue:

  • Place VCBT ID connector


These are possible causes for the issue:

  • VCBT ID connector (X6) not placed


  • Verified system status → new system under installation. System operated in the factory, so software/hardware configuration incorrect is unlikely.
  • Verified if software was upgraded or configuration was changed → no changes made in the field.
  • Verified VCBT ID connector (connection X6) is present → it is not present. This will cause the vacuum configuration of the system to be unknown to the VCBT.

Problem was solved after placing ID connector on VCBT X6 (ID connector was taken off for shipment).
