Trouble shooting
SYMPTOMS PROBABLE CAUSES SUGGESTED REMEDY
1. The dimmer is not
operating.
The Switch on the dimmer circuit
has been turned OFF.
1) Check the switch to the dimmer circuit and
switch ON.
Mains power is not restored to
lighting circuit & dimmer.
1) Replace the fuse or turn ON circuit breaker at
the switchbox.
2. The Lamps /
Luminaires flickers when
dimmer is at maximum or
minimum.
The LEDlux LED load does not
receive enough electrical
voltage/current because: 1)
Minimum/Maximum loading on
the dimmer circuit is not met,
and flickering can occur while
dimming at minimum or
maximum.
Increase/remove the loading by
adding/removing more LEDlux LED product
onto the same dimming circuit, so that the
dimmer load is within specification. Refer to
technical specification.
2) At minimum setting the
dimmer circuit provides very little
voltage/current.
Adjust the variable resistor on the LED dimmer,
to adjust the voltage/current input into the
dimming circuit until the LED stops flickering.
This may reduce the dimming range, but offer
LED light performance stability. Note: This task
can only be performed by a licensed electrician.
3. Dimming range is not
good. Cannot dim LED
load to 0% / zero light.
All LEDlux dimmable LED
drivers are different in
specification. The LEDlux
dimmer has a variable resistor to
adjust the input voltage/current
into the dimming circuit with the
variable resistor which can allow
dimming to 0%, or near 0%.
Adjust the variable resistor. This will improve
the dimming range to zero or near zero LED
light output of the dimmable LED luminaire. LED
performance may reduce slightly; however, the
dimming range is improved. Note: This task can
only be performed by a licensed electrician.
Compatibility issues - other
dimmable LED drivers may not
be compatible to dim to near
zero.
Adjust the variable resistor. This will improve
the dimming range, however, may not achieve
zero % dimming.
LED performance may reduce slightly; however,
the dimming range is improved. Note: This task
can only be performed by a licensed electrician.
