Operating instructions
1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
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.
The device is not suitable for disconnection from supply voltage.
For operation with inductive transformers, each transformer must be fused on the
primary side. Only safety transformers according to EN 61558-2-6 may be used.
These instructions are an integral part of the product, and must remain with the end
customer.

3 Function
Intended purpose
- Switching and dimming incandescent lamps, HV halogen lamps and LV dimmable
inductive transformers with halogen lamps.
- Suitable for mixed operation up to the specified output.
- Installation in appliance box to DIN 49073.
i No operation with Tronic transformers.
Product characteristics
- Phase cut-on dimming principle
- Soft locking on actuation
- Short-circuit protection through fine-wire fuse
- Electronic overtemperature protection
- Changeover switch possible in combination with two dimmers
- Control output A to output the switching status of the device to control automatic power
disconnection or relay
i Control output A may not be used as a load output.
i Flickering of the connected lamps due to undershoot of the specified minimum load or
through centralised pulses from the power stations and soft humming of the device due to
the radio interference suppressor. These are not device faults.
4 Operation
Switch light
o Press the control button.
Adjust the brightness
Light is switched on.
o Turn the control button in the clockwise direction.
The light gets brighter up to maximum brightness.
o Turn the control button in the anti-clockwise direction.
Light gets darker to minimum brightness.
5 Information for electrically skilled persons
5.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before working on the device, disconnect the power supply and cover up live
parts in the working environment.

5.2 Commissioning
Adjusting basic brightness
If necessary, the basic brightness can be set by an electrically skilled person.
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Use only insulated tools to set the basic brightness. Cover up live parts in the
working environment.
The device is connected as described above and fitted in an appliance box. The frame, central
plate and adjusting knob are not fitted.
o Switch on mains voltage.
o Press the rotary axle to switch on the lighting and turn it left to the minimum brightness.
o Set the basic brightness by turning the adjuster (8) (figure 1).
i According to EN 60669-2-1 (01.2000), lamp brightness should be detectable over the
whole load area, with darkness at – 10 % rated voltage.
o Switch on the mains voltage.
o Mount the frame and the central plate.
o Attach the adjusting knob.
o Switch on mains voltage again.

6.2 Troubleshooting
The device switches the load off and only on again after some time.
Overheating protection has tripped.
Reduce the connected load.
Check the installation situation.
The device switches the load off and cannot be switched on again.
Short-circuit protection has tripped.
Eliminate short-circuit.
Replace the fine-wire fuse, replacement fuse in the fuse holder. Use only original fuses.
