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.

Necessary accessories
For your safety
ende
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).
½
CAUTION
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.
Dimming range
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.
Setting the dimming range
|
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)
Start function
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.

Operating mode
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.

The device regularly dims down during operation
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.
