Troubleshooting at the PLR605X Display

If a PLR-controlled display section shows either a blank module or incorrect data and if
IDM is not available or does not show any visible display errors, follow these steps:
1. Check that all LEDs and the 7-segment display are illuminated. If not, check VIN
power. If VIN is within 7-24V, the power is good and the PLR should be replaced.
2. Verify the DS4 (VIN), DS5 (3.3V), and DS6 (2.5V) power indicators are illuminated. If
DS4 is not illuminated, check VIN power. If VIN is within 7-24V, the power is good and
the PLR should be replaced. If DS5 or DS6 are not illuminated, replace the PLR.
3. Run the PLR test patterns as described in PLR605X ProLink5 Display Test Patterns
(p.27). If these do not display, there is a ProLink5 system error. Check the ProLink5
connections between the module and the PLR to verify that the module has power.
Perform the module self-test to verify the module's status. Refer to the corresponding
module manual for further information on the module self-test. If the ProLink5 test
patterns do display, there is an issue either at the ProLink6 level or in the control room.
4. Run the PLR test patterns as described in PLR605X ProLink6 Display Test Patterns
(p.28). If these do not display, there is a ProLink6 system error.
5. Run the PLR self-test as described in PLR605X Self-Test Mode (p.30). If the self-test is
not completed successfully, replace the PLR.
6. Verify that either the Port A or Port B ProLink6 fiber indicator (DS13 or DS15) is toggling
as detailed in PLR6050 (p.2). If not, there is no ProLink6 feed from a master ProLink6
controller. Check fiber runs to previous PLRs to see if the link is broken. Ensure that the
master ProLink6 controller is connected and operating properly.
