All work on the device should only be carried out 

by trained and skilled electricians. Observe the 

country-specific regulations.

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.

Operating instructions

Art. no. MEG5170-0300

Art. no. MEG5170-4000

You can use the universal dimmer for CFLs / LED lamps 

(referred to below as the device) to switch and dim ohm-

ic, inductive or capacitive loads:

The device automatically recognises the connected 

load. The device is overload-proof, short-circuit-proof 

and has a soft start function.
The device has two scene buttons for retrieving, chang-

ing and saving two scenes.
When energy-saving lamps are connected, additional 

possible settings are activated. You can set the dimming 

range, switch off the start function and switch the operat-

ing mode (from trailing edge phase control to leading 

edge phase control, recommended for Osram).

The device can become damaged!
• Always operate the device in compliance with 

the specified technical data.

• Operate the device with a minimum load of 

10 VA.

• Connected devices can become damaged if 

you connect mixed loads (inductive and capac-

itive) at the same time.

• When energy-saving lamps are used: Only 

connect energy-saving lamps from the same 

manufacturer.

• The device is designed for sinusoidal mains 

voltage.

• When transformers are used: Only connect 

dimmable transformers to the dimmer.

• Dimming socket-outlets is prohibited. The risk 

of overloading and the risk of unsuitable devic-

es being connected is too high.

• If a terminal is used for looping, the device must 

be protected with a 6 A circuit breaker.

If you do not install the device in a single, standard 

flush mounting box, the maximum permissible 

load is reduced due to the restricted heat dissipa-

tion:

The following functions are only available when 

energy-saving lamps are connected.

In order to be able to dim energy-saving lamps from dif-

ferent manufacturers without faults, the dimming range 

has been restricted. However, you can adjust the dim-

ming range to your energy-saving lamp.

|

When setting the dimming range, problems may 

occur (see chapter "What should I do if there is a 

problem?")

1 Call up setting mode (the lamps are briefly switched 

off and on)

2 Set max. brightness value
3 Temporarily save max. brightness value
4 Set min. brightness value
5 Temporarily save min. brightness value
6 Save values permanently and exit setting mode (the 

lamps are briefly switched off and on)

Most energy-saving lamps need time to warm up when 

switched on. The start function is therefore activated au-

tomatically when an energy-saving lamp is connected.
The energy-saving lamp is operated at maximum bright-

ness for approx. 2 s when switched on and then dims au-

tomatically to the desired brightness.

Switching off the start function
This can be switched off for energy-saving lamps which 

do not require a start function.

When connecting energy-saving lamps, "trailing edge 

phase control" operating mode is automatically activat-

ed. 

Changing operating mode
For certain energy-saving lamps, e.g. Osram, you have 

to switch to "leading edge phase control" operating 

mode.

Standard scenes
All devices are delivered from the factory with preset-

tings for a light scene.

1 Set the brightness value.
2 Save scene: press the S1 or S2 push-button for a 

long time.

and cannot be dimmed up.
• Allow the device to cool down and reduce the con-

nected load.

The load cannot be switched back on.
• Allow the device to cool down and reduce the con-

nected load.

• Rectify any possible short circuits.
• Renew defective loads.
LV halogen lamps are not switched on with soft 

start.
Electronic transformers are detected as energy-saving 

lamps.
• Make settings for energy-saving lamps (switch off the 

start function, increase dimming range).

The load is dimmed to the minimum brightness.
The brightness has exceeded the maximum value for the 

energy-saving lamp.
• Reduce the maximum brightness value (setting dim-

ming range).

The load flickers at min. brightness setting.
The brightness has not reached the minimum value for 

the energy-saving lamp.
• Increase the minimum brightness value (setting dim-

ming range).

The load flickers continuously.
Incorrect operating mode (e.g. for Osram) set.
• Switch operating mode to leading edge phase control.
The load can only be dimmed slightly.
The dimming range is set too low.
• Increase the dimming range.
