During module configuration, the OK LED is red and the BP LED is on. If the 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 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
CompactLogix controller.
