For your safety

DANGER
Risk of serious damage to property and per-sonal injury, e.g. from fire or electric shock, due to incorrect electrical installation. Safe electrical installation can only be ensured if the person in question can prove basic knowl-edge in the following areas:

• Connecting to installation networks
• Connecting several electrical devices
• Laying electric cables

These skills and experience are normally only possessed by skilled professionals who are trained in the field of electrical installation technol- ogy. If these minimum requirements are not met or are disregarded in any way, you will be solely li-able for any damage to property or personal inju-ry.

DANGER
Risk of death from electric shock. The outputs may carry an electrical current even when the device is switched off. Always discon-nect the fuse in the incoming circuit from the sup-ply before working on connected loads.

Getting to know the dimmer module

The universal LED dimmer module (referred to below as dimmer module) is suitable for installation in a deep in-stallation box. The dimmer module is controlled with me-chanical push-buttons in parallel operation. Ohmic, inductive or capacitive loads can be switched or dimmed with it:

• Dimmable LED lamps Incandescent lamps (ohmic load)
• 230 V halogen lamps (ohmic load)
• Low-voltage halogen lamps with dimmable wound transformer (inductive load)
• Low-voltage halogen lamps with electronic transformer (capacitive load)

The dimmer module automatically recognises the connected load. It is overload- proof, short-circuit-proof, protected from overheating and it has a soft-start function.
The memory function allows the dimmer module to memorise the most recently set brightness value and retrieve it again. You can set the dimming range and adjust the operating mode (from trailing edge phase to leading edge phase).

CAUTION
The dimmer may be damaged!

• Always operate the dimmer according to the technical data provided.
• Connected dimmers may be damaged if you connect a combination of loads (inductive and capacitive) at the same time.
• The dimmer is designed for sinusoidal mains voltages.
• If transformers are used, only connect dimmable transformers to the dimmer.
• Dimming socket outlets is prohibited. The risk of overload and connecting unsuitable dimmers is too high.
• If a terminal is used for looping, the insert must be protected with a 10 A circuit breaker.

Connections, displays and operating elements

• A Programming push-button
• B Status LED
• C Function potentiometer

Mounting the dimmer module

Do not connect more than three dimmer modules to one cable with 16 A fuse protection. If you do not install the dimmer module in a single, standard flush mounting box, the maximum per-missible load is reduced due to the restricted heat dissipation:

25%

| In cavity walls
Several installed together in combi- nation
30%| In 1-gang or 2-gang surface-mount- ed housing
50%| In 3-gang surface-mounted housing

If more than one factor applies, add the load reductions together.

Wiring the dimmer module

Installing the dimmer module

Setting the dimmer module

DANGER
Risk of fatal injury from electric shock. When setting the operating mode or operating the dimmer module by means of the installed programming push-button, pay attention to particular rules for live working. Only press the programming push-button with an insulated pin, for example an insulated screwdriver that meets the requirements of EN 60900.

Setting the dimming range
The dimming range of the dimmer module can be adjusted. Depending on the dimming range of the lamp, malfunctions may occur for values near the maximum and minimum brightness. (Refer to the chapter “What should I do if there is a problem

Setting the minimum and maximum brightness

The circuit breaker is switched on. (Live working.)

1. Make sure that the connected load is turned off with the programming push-button.
2. Set the function potentiometer to MIN or MAX.
3. Press the programming push-button shortly 3 times. The dimmer module is in programming mode. The status LED flashes according to the operating mode (see “Displaying the operating mode”).
4. According to selection in step 2: Set the minimum or maximum lamp brightness by holding down the programming push-button.
5. The new value will be automatically saved after 8 seconds if the programming push-button is not pressed again during this time. The connected load is automatically switched off. The status LED lights up for 2 seconds.

Operating mode
The default setting of the dimmer module is the RC mode. The dimmer module automatically recognises inductive load (RL mode). However, not all lamps will work proper with the automatically recognised load. In this case you can switch the operating mode to RL LED.

Displaying the operating mode

The circuit breaker is switched on. (Live working!)

1. Make sure that the connected load is turned off with the programming push-button.
2. Press the programming push-button shortly 3 times. The status LED displays the current operating mode. It flashes briefly 1-3 times depending on the operating mode.

Switching the operating mode to RL LED mode

The circuit breaker is switched on. (Live working!)

1. Make sure that the connected load is turned off with the programming push-button.
2. Set the function potentiometer to RL(LED).
3. Press the programming push-button shortly 3 times. The dimmer module is in programming mode. The status LED flashes according to the operating mode (see “Displaying the operating mode”).
4. Press the programming push-button for 3 seconds. The status LED lights up for 2 seconds.

The operating mode is switched to “leading edge phase for LED lamps” (RL LED mode). In the operating mode “leading edge phase for LED lamps” (RL LED mode), LED lamps can only be connected at up to 10% of the maximum permissible dimmer load.

Resetting to default mode

The circuit breaker is switched on. (Live working!)

1. Make sure that the connected load is turned off with the programming push-button.
2. Set the function potentiometer to RESET.
3. Press the programming push-button shortly 3 times. The dimmer module is in programming mode. The status LED flashes according to the operating mode (see “Displaying the operating mode”).
4. Press the programming push-button for 3 seconds. The status LED lights up for 2 seconds.

The operating mode is switched to “trailing edge phase” (RC mode) and the minimum/maximum brightness value is reset.

Connecting the mechanical pushbutton

DANGER
Risk of death from electric shock. However the device is turned off there might be full voltage at the output. Always turn the device in the status of voltage free before starting with work.

Operating the dimmer module

• A Short press : switching on or off
• B Long press : dimming up or down

What should I do if there is a problem

The dimmer dims down regularly during operation and cannot be dimmed up again.
Allow the dimmer to cool down and reduce the connected load.
The load cannot be switched back on.

• Allow the dimmer to cool down and reduce the connected load.
• Rectify any possible short circuits.
• Renew defective loads.

The load is dimmed to the minimum brightness.

• The circuit is overloaded. -> Reduce load.
• The circuit falls short of the minimum load. -> Increase load.
• Dimming range is incorrect. -> Reduce maximum brightness value.

The load flickers at minimum brightness.
The circuit falls short of the minimum possible brightness value. Increase minimum brightness value (set dimming range).

The load flickers continuously. Incorrect operating mode set.

• Switch operating mode to “leading edge phase for LED lamps” (RL LED mode).
• Alternatively, reset operating mode to default.

The load can only be dimmed slightly.

• Set dimming range.
• Switch operating mode to “leading edge phase for  LED lamps” (RL LED mode).
• Alternatively, reset operating mode to default and set dimming range again
