If input voltage accidently falls
below 108V, the ballast power will
automatically decrease to 50% of the
set power. Turn off the ballast and
replace with correct supply voltage.
If the voltage is a bit lower than 120V,
the LED will blink and the ballast
keeps running with set wattage.
See above, reset
Disconnect the ballast. Check input
voltage, check wiring and connection,
check neutral in 3 phase systems,
then reconnect the ballast. LED on
the ballast will blink but power will
not change.
See above, reset
There is temperature sensor in the
PCB of the ballast. If it senses the
internal ballast temperature reaches
1100C, the LED will start to blink. The
ballast power will decrease to 50%
of the set power automatically. Users
should turn off the ballast or cool
down the ballast.
See above, reset
If a controller is connected, search
for loose connections, defective
contacts or short-circuits. Re-connect
the controller to the ballast or verify
whether the controller is out of order.
