COMMON SAFETY INTERLOCK FAULTS

  • MISALIGNED GUARD SWITCHES

    Machine vibration or door movement can stop the actuator engaging the safety switch correctly.

  • WORN OR DAMAGED ACTUATORS

    Repeated opening and closing can damage keyed or mechanical actuators.

  • FAILED SAFETY CONTACTS

    Internal contact faults can leave the safety system unable to confirm the guard is closed.

  • DAMAGED CABLING

    Flexing door cables and exposed field wiring can deteriorate over time.

  • SAFETY RELAY INPUT FAULTS

    The field switch may operate normally while the connected safety relay fails to receive the correct channels.

  • RESET OR FEEDBACK FAULTS

    A healthy guard switch may still not allow restart if downstream contactor feedback or reset conditions are incorrect.
