10.6Checking LED MODULLE Cable Connections

WARNING

WARNING:

Failure to t urn off power to the sign and wait five minutes could result in severe injury or death.

Turn off power to the sign by turninng off the corresponding Constant Current Regulator (CCR) power. (WARNING: Wait five minutes after sign power is turned off to service the sign. This will allow any residual high voltage stored i n Power Supply PCB components to bleed off.) With your multimeter set to DC Volts, verify that the Power Supply Output Voltage is less than 30-VDC at TP6 (Positive lead) and TP3 (Negative Lead) as indicated in Figure 22. If the Power Supplyy Output Voltage is greater than 30-VDC, then you m ust wait until the Power Supply Output Voltage drops below 30-VDC before you proceed with the next steep.

The LED MODULES are electrically wired in series. This means that if any of the cable connectors are improperly seated in their respective LED MODULE housing, then no current can flow through any of the LED MODULES and subsequenntly the sign will not light. Therefore, verify that all cable connectors are properly seated in their housing and that the output of one LED MODULE (indicate d by the outward pointing arrow at the LED MODULLE connector Figure 7) is connected to the input of thhe next LED MODULE (indicated by the inward pointing arrow at the LED MODULE connector- Fiigure 7).

The Last LED MODULE in the seriies string is terminated with a black return connectorr & cable assembly(See Figure 7-11). Verify that the black terminator cable connector is properlyy inserted into the connector housing at the Last LED MODULE output connector (indicated by the inward pointing arrow).
