Carrier returning to station

If the carrier is returning to the station again when it should go to the next station:

• Check the Product Status page for this carrier. Has the most recent operation been aborted?
• Operations can be aborted for different reasons
  • The operator used command 99 F4 (recycle) or 99 F6 (register fault without completing operation). Then the carrier will eventually come back.
  • The system can abort an operation when the carrier is unexpectedly leaving the work position without the operator pushing the button. Reasons for this can include
    • Incorrectly configured combination of chain spec + work position. If the carrier has already left the station when it should be in work position, this can happen intermittently. It then depends on the timing of either the operator pushing the button or the carrier being read on the next position on the headline.
    • Carrier was sent out in test mode
    • Duplicate carriers ids in system
    • Carrier was manually attached somewhere else with the .CarrierId F4 command.
    • Check the carrier history to get an idea of what happened.
