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 three DIP switches under the hinged cover (see fig. 2). The
dimmer 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 following two operating modes are possible. These can be selected with DIP switch 4 under the hinged
cover of the dimmer (see fig. 2).
Mode 1: 0-10 V analogue 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 wiring
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 control signals are 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: 1-10 V analogue 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
wiring 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 current flowing through the control circuit determines the light level. If the
input voltage lies below the threshold voltage (± 1.5 V), the connected load will remain off. If no control signal
is connected, 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.
3.2. 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.
3.3. Setting the lamp type

3.4. 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 § 3.5.
2. Otherwise, try out profiles Incandescent Lamp or Halogen Lamp with electronic transformer.
If one of these profiles works properly, go to § 3.5.
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.
Below you will find an example of the pros and cons of the latter two options:
Profile
Incandescent Lamp or Halogen Lamp

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
3.5 Setting the minimum level
In order to reach the (optimal) maximum range for each lamp, the minimum level can be adjusted. See fig. 3.
