LED Label Color Status Indication
GREEN The module is operating normally.
RED The module has detected an internal error or is being
initialized. If the LED remains RED for over 10 seconds, the
module is not working. Remove it from the rack and re-insert it
to restart its internal program.
ERR Red Not used.
3.2 Clearing a Fault Condition
Typically, if the OK LED on the front of the module turns RED for more than ten seconds, a
hardware problem has been detected in the module or the program has exited.
To clear the condition, follow these steps:
1
Turn off power to the rack.
2
Remove the card from the rack.
3
Verify that all jumpers are set correctly.
4
If the module requires a Compact Flash card, verify that the card is installed correctly.
5
Re-insert the card in the rack and turn the power back on.
6
Verify correct configuration data is being transferred to the module from the ControlLogix
controller.
If the module's OK LED does not turn GREEN, verify that the module is inserted completely
into the rack. If this does not cure the problem, contact ProSoft Technology Technical
Support.
3.3 Troubleshooting
Use the following troubleshooting steps if you encounter problems when the module is
powered up. If these steps do not resolve your problem, please contact ProSoft Technology
Technical Support.
