Problem – Halogen
Possible Cause
Corrective Action
All Lamps are out or not
functioning correctly.
Loose wires or
connections
Tighten or replace wires.
CCR circuit-shorted
Check circuit operation.
Sign ON/OFF switch is
closed.
Check the Sign ON/OFF switch for proper operation. Replace if necessary.
Power supply fault or CCR
is not operating correctly
Remove the cover to observe the power supply board with two LEDs located near
the notch where the wires enter the supply. LEDs are labeled D13 for Red and D12
for Green. When power is first applied, the green LED will flash (several times) first,
followed by the Red LED flashing (several times) lasting about 10 seconds, followed
by a regular green flashing “heartbeat” (at about a one blink per second rate). The
initial x-times flash is for manufacturing purposes and may vary in number from
board to board. When the regular green flashing “heartbeat” flashes, the red LED
may flicker a couple of times until the circuit stabilizes but will extinguish quickly
under normal operating conditions. If the green “heartbeat” is present and the red
LED lights solidly, this indicates that the power supply is good but there is an open
on the output of the power supply (likely either the interconnecting wires or one of
the halogen lamps are burned out). If no status LEDs light or one or both lights
solidly, and power is applied to the input, then the power supply needs to be

Light Panels are too dim.
Power supply fault or CCR
is not operating correctly

Check the CCR’s output current.
Jumper P6 on Power
Supply is set incorrectly or
missing
Check the P6 jumper setting and compare to chart on
to confirm or
correct placement of the jumper.
CAUTION
Remove power prior to changing jumper settings.
Optional Lamps Out
Indicator continues to
flash after replacing lamps.
There may be another
burnt out lamp.
Verify all lamps are tightly seated and not burnt out.
Power to sign has not
been cycled.
Remove power to sign for at least one minute and then power back up.

If you have a Halogen Sign with the 44A6225/X top-mounted power supply, please see the manual 96A0286 Rev AG on our Web site. If you wish to migrate
the old power supply to the new (44A7199/200) one used in this manual, please call your ADB representative.

There is no jumper setting for changing between 50/60 hz.
There are no jumper settings for backup lamp use.
