Dimmer

How to set up your Dimmer Extension

TECHNICAL DATA

  • Universal dimmer with 4 dimming channels
    – Channel 1 to 4: 200 Watt
    – 1030 Watt Total load
    – Designed for resistive, capacitive and inductive loads
    – Low loads are dimmable: no minimum load with trailing edge dimming
    – (high voltage LED dimming, incandescents)
    – Minimum load with leading edge dimming (inductive loads): 50 Watt
    – Wave packet control specifically suited for mains LEDs (no minimum load)
  • 8x digital inputs 24VDC
  • (For connecting to switches or window contact switches)
  • The 24VDC supply on the digital inputs is rated at 100mA, it is not intended for high loads.
  • Simple to connect to the Loxone Link
  • Ambient temperature: 5°C to 40°C, air vents must be kept clear!
  • Dimensions: 156 x 88 x 57mm (T9 housing)
  • Powered with a 24VDC power supply
  • Protection: IP20
  • Safety shutdown: If the CPU temperature increases over 79°C, all the dimming outputs are turned off. Once the temperature drops below 64°C, the respective dimmed outputs are turned on. The CPU temperature is updated on startup and if there is a temperature change of more than 5°C.

INFORMATION ON LED DIMMING

230V LED dimming of lights / strips24V LED dimming of lights / strips
With the Loxone Dimmer you can dim common 230V LED lights and strips.LED lights and strips that run on 24V DC can be dimmed with the Loxone RGBW Dimmer.

TESTED LEDS

You can dim all 230V LED bulbs marked as dimmable with the Loxone Dimmer. Due to the electronic control LED bulbs require different correction values on the Dimmer to allow for smooth dimming. This list should help you find suitable LED bulbs and their correction values.

DIMMABLE LED NOT ON OUR LIST?

Our database is constantly being expanded. If you have LED bulbs that you are using with the Loxone Dimmer that are not listed here then please contact support with all the details of your LED lamps so we can look into adding them in the list.

INSTALLATION

  • Mount the Dimmer Extension on the DIN rail
  • Connect 24V DC power supply, but do not switch on until the whole installation is completed
    (We recommend looping through the Miniserver)
  • Connect the inputs and outputs
    (We recommend splitting the channels of the dimmer across 3 phases)
  • Connect the Loxone Link
  • Note: If it’s the last extension, terminate the Loxone Link with a 120Ω resistor (included with the Miniserver)
  • Turn on the power supply
  • After a few seconds, the left LED will flash green if the extension is already configured, or orange if not

IMPORTANT INFORMATION

  • Inductive loads (e.g. conventional transformers) and capacitive loads (e.g. electronic transformers) must not be interconnected!
  • Conventional transformers must be loaded with at least 80% of the nominal load with lamps.
  • The Dimmer Extension is not suitable for speed control of motors, since back EMF with voltage spikes of over 300 V causes permanent damage. If you have any questions regarding this please contact Support.
  • When using the Dimmer for mains LEDs each channel should be de-rated by 50% due to the high inrush currents. This means that the first channel would be rated at 200 Watts and the other channels at 105 Watts.

USING THE DIMMER EXTENSION

The Loxone Dimmer Extension is an RLC Dimmer. That means you can dim resistive, inductive and capacitive loads.

Icon Exclamation Mark LoxoneWhen the left status LED on the Dimmer extension is red the measurement of the frequency of the dimming channels is being performed.

DIMMING TYPES

You can change what type of load is being dimmed.

Dimming type Type of load Example
Leading edge dimmingResitive or inductive loadConventional low voltage halogen transformers
Trailing edge dimmingResistive or capacitive loadsIncandescents, electronic high voltage halogen transformers
Mains LEDs (leading edge)Mains LEDs (leading edge) ResistiveMains 240V LEDs
Mains LEDs (trailing edge)ResistiveMains 240V LEDs

CORRECTION

If an incoming value is outside the range (0 to 10) for instance 0-100% with 0-10VDC, this can be adjusted for using the corrector.

Dimmer Correction Graph

Correction example for a dimmer

The analogue output from the dimmer function block gives out a 0-10V signal, the output of the Dimmer Extension is 0-100%, so the corrector must be used for the scaling to be correct. The scaling is linear. If 1V at the analogue output corresponds to 10%, then the following settings must be used:

Input voltage 10V
Display value 10%
Input voltage 210V
Display value 2100%

Since high voltage LEDs have their own electronics, it might be that at 70%, they are already at their full brightness. The corrector can also be used here:

Input voltage 10
Display value 10%
Input voltage 2100%
Display value 270%

DISPLAY

In the section ‘Display’, you can choose the desired units. It can be useful to read the help window, as shown in the screenshot.

If you want a status display of the output, then tick the box next to ‘Show status only’.
