Caution: Some of these troubleshooting steps are performed with live voltage applied. The
assembly should be moved to a safe area before beginning work. A qualified and properly trained
technician must perform these steps.
1) Verify Power supply has power.
2) Using a voltmeter set to DC; measure the voltage on the input of the barrier. Voltage should be
24VDC. If no power is present replace power supply.
3) Using a voltmeter set to DC; measure the voltage on the output of the barrier. Voltage should be
between 11VDC and 15VDC with the illuminator connected. 24VDC with no illuminator
connected. If no power is present replace barrier.
WARNING: DO NOT MEASURE VOLTAGE ACROSS INPUT AND OUTPUT. UNSAFE
LEVEL OF CURRENT COULD BE SENT INTO AN INTRISCIALLY SAFE AREA.
4) Verify wires are connected properly and no connections are loose.
5) Inspect wires for damage or loose connections. Replace as needed.
6) Unscrew blue power cord or field wireable connector at LED bar. Inspect the 4 pins inside end
connector to make sure they are straight and undamaged. If pins are bent, use a small pair of
needle-nose pliers to straighten bent pins. If pins are missing, contact factory.
