During module configuration, the OK LED is red and the BP ACT LED is on. If
the APP, BP ACT and OK LEDs blink at a rate of every one-second, this
indicates a serious problem with the module. Call ProSoft Technology Technical
Support to arrange for repairs.
6.2.1 Clearing a Fault Condition
Typically, if the OK LED on the front of the module remains RED for more than
ten seconds, a hardware problem has been detected 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 all jumpers are set correctly.
4 Re-insert the card in the rack and turn the power back on.
5 Verify correct configuration data is being transferred to the module from the
CompactLogix 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.
