10.3Measuring Input Current (Signs Without Optional Power Switch)

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.

Open Power Supply cover (See Figuure 18). Disconnect female crimp receptacle at CN117 from Power Supply Board. (Note: When removing female crimp receptacle, grasp by the terminal, not the wire.) Disconnect female crimp receptacle from CN18 and connect to CN17. Place current claamp around primary power wire and connect to a true rms current meter. Turn on power to the CCRR. Current should measure between 2.7-ARMS and 6.7-ARMS depending on the CCR current level or currrent step.

Upon completing the measurement of the input current, turn off power to the CCR. Remmove the current clamp. Disconnect the female crimp receptacle at CN17 and reconnect to CN18. Reco nnect the female crimp receptacle attached to wire BRPH to CN18. Close the Power Supply Box cover.

10.4Measuring Input Current (Signs With Optional Power Switch)

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 sign by toggling sign power switch to the off position (See Figure 6). Turn off power to the sign. (WARNING: Wait fiv e minutes after sign power is turned off to servicee the sign. This will allow any residual high voltagge stored in Power Supply PCB components to bleed off. ) With your multimeter set to DC Volts, veerify that the Power Supply Output Voltage is less than 30-VDC at TP6 (Positive lead) and TP3 (Negattive Lead) as indicated in Figure 22. If the Power Supply Output
