Operating instructions
1 Safety instructions
Electrical devices may only be mounted and connected by electrically skilled persons.
Serious injuries, fire or property damage possible. Please read and follow manual fully.
Danger of electric shock. Always disconnect before carrying out work on the devise or load. In
so doing, take all the circuit breakers into account, which support dangerous voltages to the
device and or load.
These instructions are an integral part of the product, and must remain with the end customer.

– Parallel switching of up to four DALI potentiometers with power supply unit with the option
of supplying up to 104 DALI subscribers.
– The DALI potentiometer without a power supply unit is powered using the DALI voltage
and serves as an additional control section.
– Saving of colour temperature limiting values and a basic or switch-on brightness.
To ensure fault-free operation, do not combine the device with other DALI controllers.
Behaviour after a mains voltage failure
When the mains voltage returns, the lighting is switched to the brightness and colour temperat-
ure present before the mains voltage failed.
4 Operation
Operation can take place from multiple control sections and always applies to all connec-
ted subscribers (broadcast).
Switch light
￭ Press the control knob.
Adjust the brightness
￭ Turn the control knob.
Turn slowly = Brightness change small
Turn quickly = Brightness change great
Setting colour temperature
Figure2
￭ Turn pressed control knob.
Turn left (W) = warmer light (reduce colour temperature)
Turn right (C) = colder light (increase colour temperature)
Save switch-on brightness
If the lighting is not always to be switched on with the same brightness, then this can be saved
as a switch-on brightness.
￭ Switch on light.
￭ Set required switch-on brightness.
￭ Press the control knob briefly twice in succession (double-click).
The lighting briefly switches to maximum brightness twice. The switch-on brightness is
saved.
If the lighting switches off after the double-click, then the time between the first and
second presses was too long.
Delete switch-on brightness
￭ Switch the light off.
￭ Press the control knob briefly twice in succession (double-click).
After about 2 seconds the lighting switches to maximum brightness.

5 Information for electrically skilled persons
DANGER!
Mortal danger of electric shock.
Before carrying out work on the device or load, disengage all the corresponding cir-
cuit breakers. Cover up live parts!
5.1 Fitting and electrical connection
Connecting and fitting the device
Figure3
(1) DALI potentiometer with power supply unit
(6) DALI subscriber e. g. DALI electrical ballast
(7) DALI potentiometer without power supply unit
￭ Connect the DALI potentiometer and DALI electrical ballast according to the wiring ex-
ample (Figure 3). In so doing, observe the data of the electrical ballast manufacturer.
￭ When switching multiple DALI potentiometers with a power supply unit in parallel, ensure
correct polarity.
￭ If multiple 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 guaran-
teed.
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.
The control cable and load cable can be run in a shared cable, e.g. NYM J 5×1.5.
The connected DALI subscribers may be operated on different phases.
5.2 Commissioning
Saving a basic brightness
The basic brightness should be set to a state that does not directly lead to an increase in bright-
ness when turning the DALI potentiometer at minimum brightness.

Tunable white
￭ Set lighting to minimum brightness.
￭ Turn the DALI potentiometer to the point that where the brightness begins to increase.
￭ Press the control knob for longer than 10 seconds.
The lighting switches briefly off and on again. The basic brightness is saved.
Saving colour temperature limiting values
The setting range of the DALI potentiometer can be adjusted to the colour temperature of the lu-
minaire with this setting.
When saving the colour temperature, you must ensure that the last turn of the pressed
control knob (Figure 2) is made to the left for the warmest light colour (W) and to the right
for the coldest light colour (C).
￭ Turn pressed control knob to the left (W) until reaching the warmest light colour required,
and hold it in this position for more than 10 seconds.
The light switches off three times and then switches on again. The warmest light colour is
saved.
￭ Turn pressed control knob to the right (C) until reaching the coldest light colour required,
and hold it in this position for more than 10 seconds.
The light switches off three times and then switches on again. The coldest light colour is
saved.
Deleting the basic brightness and colour temperature limiting values
￭ Switch the lighting off.
￭ Press the control knob for longer than 10 seconds.
Briefly switch the lighting to maximum brightness and then off again. The stored values
are deleted.
