DriveCore Install DA Series Operation Manual

Troubleshooting

CONDITION: Power indicator is

off

Mains indicator is on.

POSSIBLE REASON:

• The amplifier’s Power switch is off.

CONDITION: Power indicator is

off

Mains indicator is off.

POSSIBLE REASON:

•  The power supply breaker has tripped.
•  The amplifier has lost AC Power.
•  The amplifier is not plugged in to the power

receptacle.

CONDITION: Power indicator is
flashing.

POSSIBLE REASON:

• The AC line voltage has dropped below 10%

or has risen above 10% of the nomi nal line

voltage of the power supply.

• When the Amp is in Sleep Mode as set by the

AUX Port, the amplifier will not power up

until the ground closure on the AUX Port is

released. When the power button is pushed

in this condition, the Power Indicator will

flash for 2 – 3 seconds.

CONDITION: Thermal indicator

is on.

POSSIBLE REASON:

• The amplifier is becoming too hot for safe

operation. Allow amplifier to cool.

Check for loads less than 2Ω, and for

excessive input levels. Check

for proper ventilation and proper

mode-switch set ting.

CONDITION: Fault indicator is

flashing.

POSSIBLE REASON:

• There are a number of conditions that result

in the Fault indicator flashing: temperature

above 98C, DC/LF protection is engaged, HF

detect, output short

circuit detected. These conditions should all

be checked and attempted to be resolved

before the amp is shipped back for service.

“Off/Flashing/On” above means that

the LED can be off, or flashing, or on.
