Operating Instructions
Universal dimmer

1. Warning

Attention:
Electrical equipment must be installed and fitted only by qualified
electricians and in observance of the applicable accident prevention
regulations.
Not suitable for disconnecting.
When the universal dimmer is off the load is not electrically isolated
from the mains.
When using conventional transformers, protect the primary side of
each transformer by a fuse as indicated by the manufacturer.
Do not connect any electronic lamps, e.g. switchable or dimmable
compact fluorescent lamps or LED lamps. Device can be damaged.
Only use safety transformers as per EN 61558-2-6.
Non-observance of the installation instructions may cause fire or
other hazards.

2. Function

Universal dimmer for switching and dimming extensive light sources such
as:

• 230 V incandescent lamps.

• 230 V halogen lamps.

• LV halogen lamps in conjunction with TRONIC transformers

• LV halogen lamps in conjunction with conventional transformers.

Switching and dimming commands are given when the covers of the
dimmer, of the extension insert or of the radio transmitter are actuated .
The universal dimmer works on the basis of the twoarea principle, i. e.
there is one touch area each for the ‘brighter’ and ‘darker’ dimming
directions. The lights are turned on by a lamp-saving soft start. This
Operating Instructions paper describes the functionality in combination
with the manual attachment.

Operation from the switched-off state:

Short touch (less than 400 ms)
UPPER or LOWER touch area or full area: ON
Longer touch (more than 400 ms):
UPPER touch area: Dimming from minimum to maximum brightness.
LOWER touch area: Turning on to minimum brightness.

Operation from the switched-on state:

Short touch (less than 400 ms):
UPPER or LOWER touch area or full area: OFF
Longer touch (more than 400 ms):
UPPER touch area: Increasing the light intensity to maximum

(dimming up).

LOWER touch area: Decreasing the light intensity

to minimum (dimming down).

Full-area operation (3 s min.): The current brightness is stored and
adjusted upon restarting (short actuation).

The storing process is indicated by a soft start.

3. Installation Instructions

Fit universal dimmer insert (1) into a box as per DIN 49073 (Fig. A).

A

The connecting terminals of the insert must be at the bottom. Use the
universal dimmer insert only in combination with an attachment. Plug
attachment (2) onto the insert (1) together with frame (3). Plug on the
attachment prior to applying the mains voltage. Do not change the
attachment while the mains voltage is on, or malfunctioning will be
caused. After installation of the universal dimmer, the brightness value in
memory is the maximum brightness.

Do not connect capacitive loads (e. g. TRONIC transformers) and
inductive loads (e. g. conventional transformers) to the universal
dimmer at the same time.
