4.1.2 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
CompactLogix or MicroLogix 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.
4.1.3 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.
Processor Errors
Problem Description Steps to take
Processor Fault Verify that the module is plugged into the slot that has been configured for
the module.
Verify that the slot in the rack configuration has been set up correctly in
the ladder logic.
Processor I/O LED
flashes This indicates a problem with backplane communications. Verify that all
modules in the rack are configured in the ladder logic.
The module has a power supply distance rating of 2 on CompactLogix,
meaning that there must not be more than one other module between the
MVI69-DFNT module and the power supply. If the module is used in a
MicroLogix system, verify that the backplane can supply the 800 mA
required by the module.
