Universal modular dimmer with PLC interference suppression, 5-350W analogue.
1. DESCRIPTION
This universal, modular dimmer is intended for DIN-rail mounting and is 1 TE wide (17.5 mm).
The dimmer is connected with three wires and is suitable for dimming dimmable LED lamps, dimmable
economy lamps (CFLi), halogen lamps and incandescent lamps. The dimmer functions according to both the
phase control and reverse phase control principle and is controlled via a NO push-button (170-0000x) with
0/1-10V analogue control. The choice of lamp type can be set using the first three DIP switches under the
hinged lid (see fig. 2). The dimmer is equipped with an automatic detection and indication of malfunctions
(overload, short circuit, etc.).

2. MOUNTING AND CONNECTION

To connect the load and the necessary input 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 a malfunction has occurred, then the LED will flash. Make sure that no mixed
loads are used on the dimmer.
Installation recommendations
- The dimmers should ideally be fitted at the bottom of the electrical cabinet.
- If modular dimmers are fitted near to one another in the electrical cabinet, you can only connect 80% of the
maximum permissible power. A minimal distance of 20 mm is required in order to utilise the full, maximum
power.
- 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. Install a ventilator if necessary.

3. OPERATION AND USE

3.1. General operation

Two operating modes are possible. These can be selected with DIP switch 4 under the hinged lid of the
dimmer (see fig. 2).
Mode 1: analogue 0-10 V control
When this mode is selected, the dimmer will accept a voltage control signal from 0 to 10 V according to IEC standard
61131-2. This mode is selected by switching DIP switch 4 ON (upward) (see § 3.3.). For the connection diagram,
see fig. 1a. From 0 to 10 V, lighting regulation is possible from the minimum to the maximum light intensity. The
0-10 V voltage control signal is used in professional applications such as the Nikobus dim controller or PLC. If
the input voltage lies below the threshold voltage (± 1 V), the connected load remains off. If the input voltage
is equal to the threshold voltage, the connected load will switch on to the minimum light intensity. If the input
voltage is 10 V, the connected load will switch on to the maximum light intensity.
Mode 2: analogue 1-10 V control
When this mode is selected, the dimmer operates via a current control signal from 1 to 10 V according to
EN60929 standard. This mode is selected by switching DIP switch 4 OFF (downward) (see § 3.3.). For the
connection diagram, see fig. 1b. From 1 to 10 V, lighting regulation is possible from the minimum to the
maximum light intensity. The intensity of the voltage flowing through the control circuit determines the light
level. If the input voltage is below the threshold voltage (± 1.5 V), the connected load will remain off. When
no control signal is connected, the connected load will switch on at the min. light intensity. If the input voltage
is 10 V, the connected load will switch on to the maximum light intensity. If you use a different type of 1/10V
control than the Niko rotary dimmer 310-0110x and you wish to dim your lighting circuit to a minimum, you
must place a resistance of 10k Ohm in series with the +-line for the 1-10V connection.
3.2. Meaning of the red indication LED
The LED lights up: - the dimmer is connected correctly (when installing),
- and the load is switched on.
The LED flashes: - malfunction; the dimmer is not connected correctly, overload, short-circuit
incorrect setting. See Troubleshooting in §4 of this manual.
3.3. Permitted loads
The following table provides an overview of the maximum load that is permitted per lamp type at an ambient
temperature up to 35°C.

3.4. Adjust the dimmer settings according to the type of lamp
You set the correct load with the DIP switches as follows.
Halogen lamp with electronic transformer – reverse phase control
LED 1
Halogen lamp with ferromagnetic transformer – phase control
LED 2
LED 3* Dimmable lamp or dimmable economy lamp - reverse phase control
LED 4* Dimmable lamp or dimmable economy lamp - phase control
LED 5 Dimmable LED lamp - reverse phase control

(*) These lamp profiles are equipped with boost function. This means that upon switching on, the lamp will
briefly shine brightly before going to the desired dimming level (if the memory function has been activated).
These profiles have been specifically made for lamps which cannot be switched on again when dimmed low.
3.5. Select profile for LED lamps
To select the right profile for the installed LED lamps, you proceed as follows:
1. Try out profiles LED 5 and LED 6, one after the other.
If one of these profiles functions properly, go to § 3.6.
2. If not, try the profiles LED 1 and LED 2, one after the other.
If one of these profiles functions properly, go to § 3.6.
3. If not, it means the LED lamps need a lot of energy to start up. In this case, choose from the lamp profiles LED
3, LED 4, LED 7 or LED 8. These profiles have a boost function ensuring that, when starting up, the lamps
receive enough energy before going into the desired dimming level.
We provide an example of the advantages and disadvantages of the final two options below:
Profile
LED 1 or LED 2
Advantages
The lamp does not shine bright for a
moment after being switched on
Disadvantages • The lamp cannot be dimmed to its
minimum level
• In certain cases the difference that can
be reached in light output is limited
3.6. Setting the minimum level
In order to reach the (optimal) maximum range for each lamp, the minimum level can be adjusted. See fig. 3.

The dimming profile is incorrect. For dimmable LED lamps: test
all lamp profiles one by one and

For halogen lamps with ferro-
magnetic transformers, choose

For dimmable economy lamps,
choose a lamp profile with boost
