Mounting And Connection; Operation And Use - Niko 330-00700 Manuel D'installation

Read the complete manual before carrying out the installation and activating the system. Keep the
manual for future reference.
1. DESCRIPTION
This 350 W universal modular dimmer is intended for DIN-rail mounting and is 1 U wide. The device is suitable
for dimming resistive, inductive and capacitive loads as well as dimmable LED lamps and economy lamps
(CFLi). The dimmer functions both as a phase control dimmer and as a reverse phase control dimmer. The
choice of lamp type can be set using the first 3 DIP switches under the hinged cover (see fig. 2). The dimmer
can be used with or without memory and is equipped with an automatic detection and indication of faulty
conditions (overload, short circuit ...).

2. MOUNTING AND CONNECTION

To connect the load and the necessary power supply voltage, see fig. 1. If everything is correctly connected
and the power supply and the lamp are switched on, then the indication LED on the dimmer will be on. If an
error has occurred, then the LED will flash. Make sure that no mixed loads are used on 1 dimmer.
Mounting recommendations
- Preferably place the dimmers at the bottom of the electrical cabinet.
- Check the temperature. If the temperature in the electrical cabinet rises too high (max. 35°C), provide
additional ventilation. Provide sufficient space at the top of the cabinet. Place a ventilator if necessary.

3. OPERATION AND USE

3.1. General operation
The dimmer is controlled via an NO push button (230 Vac or 8-24 Vac/Vdc). Press briefly to switch on and off.
Hold down to dim up and down. When holding down, the dimming direction is switched after each interruption
(dimming up -> stop -> dimming down-> stop -> dimming up -> etc.). Once the maximum intensity has
been reached, the dimming level remains unchanged. The last dimming level reached before the dimmer
is switched off is saved in a memory (see § 3.3.). Up to 30 NO contacts (170-0000X) can be connected in
parallel at any one time (max. distance 100 m).
3.2. Two extra control modes
The following two additional operating modes are possible. These can be selected with DIP switch 4 under the
hinged cover of the dimmer (see fig. 2).
Mode 1: One-button control
By selecting this mode, the dimmer works with an NO push-button control (230 Vac or 8-24 Vac/Vdc). Press
briefly to switch on and off. Hold down to dim up and down. When holding down, the dimming direction is
switched after each interruption (dimming up -> stop -> dimming down-> stop -> dimming up -> etc.). The
last dimming level reached before the dimmer is switched off is saved in memory (see § 3.3.). This mode is
selected by turning DIP switch 4 off (downward) (see § 3.6). For the wiring diagram, see figure 1a (one-button
control).
Mode 2: Staircase function
By selecting this mode, the lighting switches off automatically after 3 minutes. This mode is selected by
turning DIP switch 4 on (upward) (see § 3.6). For the wiring diagram, see figure 1b (staircase function).
3.3. Memory function
The dimmer can be used with or without memory. The standard setting of the dimmer is without memory
function. You use the control button to change this function. Dim up to the maximum lighting intensity and
then continue to press the control button for 10 s. After 10 s the light dims from 100 % to a lower light level
to indicate that this function has been switched on. After this change in light intensity, immediately release
the push button. Repeat the procedure to deactivate the memory function. This function, and the last set
light level, is stored in a non-volatile memory, i.e. they will not be lost in the event of a power failure. With the
memory function, the dimmer switches on the first time at a light level chosen by the manufacturer. Thereafter,
the dimmer switches on at the last set value.
When dimming dimmable economy and LED lamps with the memory function activated, the dim profile is set
up so that the dimmer is first switched on to its maximum capacity (boost function) for less than one second
and then returns to the dimming level saved in memory. This ensures that each lamp, even those with memory
function, can be switched on.
With memory
- Press briefly = on at previous level/off.
- Hold down when off = the dimmer dims up from the minimum light level.
- When dimming up, the dimmer stops at the maximum.
- When dimming down: the dimmer stops for 2 s at the min. and then dims up.
- A renewed (long) press reverses the dimming direction.
Without memory
- Press briefly = on at maximum/off. The rest of the operation is the same as the operation with memory.
Push-button control
Press briefly < 400 ms Hold down > 400 ms
= on/off = dimming up/dimming down
3.4. All-off function
If another control point is connected to the all-off input
connected to this dimmer. For the wiring diagram, see fig. 1 c (all-off function).
3.5. Meaning of the red indication LED
The LED turns on: - the dimmer is connected correctly (when installing),
- and the load is switched on.
The LED is flashing: - error condition: the dimmer is not connected correctly or there is an overload,
short-circuit or an incorrect setting.

(*) These lamp profiles are equipped with a boost function, which means that when switched on, the lamp will
be bright for a brief moment before going to the desired dimming level.
3.7. Selecting the profile for LED lamps
In order to select the right profile for the installed LED lamps, you proceed as follows:
1. Try out profiles LED 1 and LED 2, one after the other.
If one of these profiles works properly, go to § 3.8.
2. Otherwise, try out profiles Incandescent Lamp or Halogen Lamp with electronic transformer.
If one of these profiles works properly, go to § 3.8.
3. Otherwise, this is an indication that the installed LED lamps need quite a lot of energy in order to come on.
It is therefore advisable to choose profile LED 3 or LED 4, as these profiles are equipped with a boost function
that ensures that when switched on, the lamps receive enough energy before switching to the desired
dimming level (with activated memory function).
Below you will find an example of the pros and cons of the latter two options:
Profile Incandescent Lamp or Halogen Lamp
with electronic transformator
Advantage The lamp isn't bright when switched on
Disadvantages
• The lamp cannot be dimmed to its
minimum level
• In certain cases, the difference in
attainable light output is limited
Switch the dimmer off and on after setting the minimum level. If the lamp is not on (with activated memory
function), select a lamp profile with boost function (CFLi1, CFLi2, LED 3 or LED 4), see § 3.6.
3.8 Setting the minimum level
In order to reach the (optimal) maximum range for each lamp, the minimum level can be adjusted. See fig. 3.
