1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Danger of electric shock. Always disconnect before carrying out work on the devise or
load. At the same time, take into account all circuit breakers that supply dangerous
voltage to the device or load.
Danger of electric shock. Device is not suitable for disconnection from supply voltage.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
These instructions are an integral part of the product, and must remain with the end

3 Function
Intended use
Brightness setting for luminaires with DALI interface
Installation in appliance box acc. to DIN 49073
Product characteristics
Up to 64 DALI subscribers can be controlled
Parallel control of multiple control sections
Protection against connection to mains voltage by means of integrated fine-wire fuse
Light Management
DALI potentiometer insert
Basic brightness adjustable
To generate the DALI voltage, a power supply is required that complies with the DALI
specifications according to IEC 60929, e.g. from Helvar or Philips.
i To ensure fault-free operation, do not combine the device with other DALI controllers.
Behaviour after a mains voltage failure
After the return of mains voltage the switching state and the brightness of the last potentiometer
switched are restored.
After brief power failures or in case of multiple-phase operation restoration can take up to 30
seconds. During this time period a value – PowerON-Level – stored in the DALI electrical
ballast is called up.
i The brightness of the lighting for missing DALI telegrams – PowerON-Level – and in case
of failure of the DALI system voltage – SystemFailure-Level – is stored in the electrical
ballast and cannot be changed via the DALI rotary potentiometer.
4 Operation
i Operation can take place from multiple control sections and always applies to all the
connected subscribers, broadcast. The lighting always takes on the value of the
potentiometer just operated. Therefore there may be a jump in brightness at the beginning
of operation.
Switch light
o Press the control knob.
Adjust the brightness
Light is switched on.
o Turn the control knob.
5 Information for qualified electricians
5.1 Installation and electrical connection
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.

DALI power supply
DALI subscriber e. g. DALI electrical ballast
When selecting the DALI power supply, take into account the number of DALI subscribers
and DALI potentiometers.
i Ensure that the control cable is of the appropriate type, cross-section and routing for the
VDE specifications for 250 V cable, control voltage has basic insulation.
i Control cable and load cable may be routed in a common cable, e.g. NYM J 5 × 1.5.
i The connected DALI subscribers may be operated on different phases.
o Connect the DALI potentiometer and DALI electrical ballast according to the connection
diagram (picture 2). In so doing, observe the data of the electrical ballast manufacturer.
o If multiple miniature circuit breakers supply dangerous voltages to the device or load,
couple the miniature circuit breakers or label them with a warning, to ensure disconnection
is guaranteed.
5.2 Commissioning
Saving the basic brightness
The basic brightness should be a state when turning the DALI potentiometer does not directly
lead to an increase in brightness.
o Switch the lighting on minimum brightness.
o Turn the DALI potentiometer to the point that where the brightness begins to increase.
o Press the control knob for longer than 10 seconds.
The lighting switches briefly off and on again.
The basic brightness has now been saved, and will be adopted by the potentiometer the
first time the actuating knob is turned.
i Any basic brightness can be saved from which it is possible to add brightness.
Deleting the basic brightness
o Switch the lighting off.
o Press the control knob for longer than 10 seconds.
Briefly switch the lighting to maximum brightness and then off again. The basic brightness
has been deleted.
