Normal Operation; Technical Data - Niko 310-0190X Mode D'emploi

4.3. Normal operation

This dimmer operates according to the principle of phase control or reverse phase control, depending on the
setting (see § 3.1.).
Using the control button Result
push You switch the light on or off.
rotate You adjust the light intensity. Once you have reached the maxi-
mum light intensity, the dimming level remains unchanged.
rotate quickly You make the light intensity decrease or increase rapidly.
rotate slowly You set the light intensity more precisely.
Please note: The dimmer is never electrically separated from the mains voltage. All parts remain connected
to the mains voltage even if the load (e.g. the light) is off.
4.4. Memory function
Use
The standard setting of the dimmer is without memory function. You can use the fourth DIP switch behind the
control button to activate or deactivate this function:
DIP switch position
DIP switch up
DIP switch down
The last dimming level set before switching off the dimmer is saved in the permanent memory of the dimmer if
the memory function is activated. In the event of a power failure, this value will not be lost.
If the memory function is activated, the dimmer switches on for the first time at the default dimming level
selected by Niko. After that, the lighting will be dimmed at the last set value.
Use dimming profiles LED 5, LED 6, LED 7 and LED 8 with the memory function
The dimming profiles have been set up in such a way that the dimmer is briefly switched on at the maximum
light intensity (for LED 5 and LED 6) or at 50% of the light intensity (for LED 7 and LED 8), before switching to
the memory setting. This enables every dimmable economy or dimmable LED lamp to be switched on.
5. TROUBLESHOOTING

There is a PLC malfunction.
The lamp is not suitable.
The dimmer is defective.
The lamp cannot be switched off. There is leakage current due to
certain dimmable LED lamps or
dimmable economy lamps with a
low electrical load. Leakage cur-
rent can also occur due to capaci-
tive effects of long cabling.

Action
Check if the lamp is dimmable.
This is shown on the packaging
by the following symbol:
Check whether the load is too
high. When doing this, keep in
mind the reactive power of fer-
romagnetic transformers.
Check the temperature in the
flush-mounting box (max. 35 °C).
Check whether mixed loads have
been used, and make sure that
only one type of lamp load is in
the lighting circuit.
For dimmable LED lamps: test
all lamp profiles one by one and
choose the profile that works
best. Dimmable LED lamps that
require a boost function (do not
start up at minimum dimming)
can be controlled with lamp
profiles LED 3, LED 4, LED 7, or
LED 8.
For incandescent lamps and
halogen lamps with electronic
transformers, choose lamp profile
LED 1.
For halogen lamps with ferromag-
netic transformers, choose lamp
profile LED 2.
For dimmable economy lamps,
choose a lamp profile with boost
function: LED 3 or LED 4.
Check if the lamp is dimmable.
This is shown on the packaging
by the following symbol:
Increase the minimum dimming
level or use a profile with boost
function (LED 3, LED 4, LED 7 or
LED 8).
Choose another profile and adjust
the minimum dimming level.

Replace the lamp if it flashes
when dimming the light up and
down.

Fit another lamp with a higher
minimum electrical load. Or fit a
LED compensator (09-016-10
or 310-0500x) over the lamp,
between the switching wire and
the neutral conductor.
