or stays lit, then the second LED MODULE and the cable from the first LED MODULEE to the second LED MODULE are operating norm ally.

Turn off main power to the sign. Wait five minutes for the high voltage to dissipate. Verify that the

output voltage is less than 30-VDC with a multimeter as described in the opening paragraph of this section. Replace the black return cable connector with the first LED MODULE output cable connector. Replace the black return cable conn ector in the output connector housing of the last LE D MODULE.

If the sign does not light at all, then replace the second LED MODULE and/or the cablee connecting from the output connector of LED MODUULE #1 to the input of LED MODULE #2 (see Section 10.10). Then repeat the test outlined above in thiis section.

10.9Continue Checking the Rest of the LED MODULES

It is assumed that the first two LED MODULES have been checked successfully as des cribed in previous two sections. For signs with more than two LED MODULES, continue checking the remaining LED MODULES one at a time and in numerical sequence (e.g. LED MODULE #3, LED MOODULE #4….LED

MODULE #Last). Use the same method as we have outlined in previous section.

For example, suppose we have a siggn with 6 LED MODULES (See Size 2, 2-Modules, Figure 9) and we have checked all the LED MODULES in sequence from 1 to from 4 and found that the sign momentarily lit. Then we would use the followinng procedure to test the 5th LED MODULE.

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.

Remove the black return cable connnector from the 6th LED MODULE output cable connnector (see Figure 20). Replace the output cable conneector in the LED MODULE #5 with the black return cable connector.
