Channel Status Indicators

Interpret Output Channel Status Indicators
Indicator State
Description
Recommended Action
Off
One of the following conditions exists:
  • The module is not powered.
  • The module is powered but connection is not established from the controller to module.
  • The module is powered, but the input channel is disabled.
Complete one of the following:
  • If you expect the module to be powered but it is not, complete the following:
    • Confirm that the system is powered.
    • Confirm that the module is installed properly.
  • If the module is powered but the channel is not operating as expected, use the Studio 5000 Logix Designer application to confirm that the channel is not disabled and the module has a connection to the controller.
    The Connection view in the Module Properties indicates if the connection is running or faulted. If the connection is faulted, the Connection view indicates error information.
  • If the channel is disabled, no action is needed.
Steady yellow
The output channel is operating normally.
None
Flashing red
One of the following conditions exists:
  • There is no SA power to the module, or SA power voltage is not in the valid range.
  • A wire is disconnected from the output. That is, a No Load condition exists.
  • The module is driving a current from the channel greater than the maximum current level the channel can handle. That is, a Short Circuit condition exists.
One of the following:
  • If there is a SA power fault, see the recommended action given for steady red indicator state in SA Power Indicator table above.
  • Check the wiring at the output channel. If necessary, reconnect the wire.
  • Troubleshoot the application to make sure an acceptable level of current is driven from the channel.
Alternating yellow/red
Calibration is in progress.
Successfully complete the calibration process.
Steady red
An issue has occurred that is internal to the module. The following are example issues that can cause the status indicator to be steady red:
  • A calibration fault occurred on the channel.
  • The module has experienced a nonrecoverable fault.
Complete one of the following:
  • If the indicator turns steady red after a calibration process, you can either perform a successful calibration or cycle the power to recover the fault.
  • If it is not caused by the calibration, cycle the power to recover the fault. If the condition is still present, replace the module.
