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.

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.

The load is not electrically isolated from the mains even when the device is switched off.

Fire hazard. For operation with inductive transformers, each transformer must be fused on the primary side in accordance with the manufacturer's instructions. Only safety transformers according to EN 61558-2-6 may be used.

Do not connect any electronic lamps, e.g. switchable or dimmable compact fluorescent lamps or LED lamps. Device can be damaged.

These instructions are an integral part of the product, and must remain with the end customer.

3 Function

Intended use

- Switching and dimming of incandescent lamps, HV halogen lamps and dimmable inductive transformers or Tronic transformers with halogen lamps

- Suitable for mixed operation up to the specified output (see chapter 6.1. Technical data)

- Installation in appliance box acc. to DIN 49073 i No mixed operation of Tronic and inductive transformers.

Product characteristics

- Connection of more than one dimmer is possible

- Electronic short-circuit protection with permanent switch-off after 7 seconds at the latest

- Electronic over-temperature protection

- Bulb-preserving soft start

- Power extension through power boosters (see power booster instructions)

- Automatic setting of the dimming principle suitable for the load

Phase cut-off

Phase cut-on i Flickering of the connected lamps due to undershoot of the minimum load or through centralised pulses from the power stations. Brief flickering upon load detection of ohmic loads. No operation is possible during load detection. These are not device faults.

4 Operation

Switch light o Press the control button.

Light is switched on again with the last brightness level set or switched off.

Switching the light on with minimum brightness

Light Management o Turn control button a quarter turn in the anti-clockwise direction and press control button

(picture 2).

Switching the light on with maximum brightness picture 3: Maximum brightness o Turn control button a quarter turn in the clockwise direction and press control button

(picture 3).

Adjusting the brightness

Light is switched on. o Turn the control button in the clockwise direction.

The light gets brighter. o Turn the control button in the anti-clockwise direction.

Light gets darker. i The dimmer detects the turning speed: with quick turning there is 360° between minimum and maximum brightness, with slow turning 720°.

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 carrying out work on the device or load, disengage all the corresponding circuit breakers. Cover up live parts in the working environment.

Connecting and mounting the dimmer picture 4: Connection diagram for dimmer with extension o Remove approx. 15 mm of insulation from the connecting cables. o Connect dimmer (1) and optionally an extension (7) according the connection diagram

(picture 4). 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 release is guaranteed. o Install the device in the appliance box. Fit dimmer in appliance box, connection terminals must be at the bottom. o Mount the frame and the central plate. o Attach the control button.

Pull the connecting cable out of the push terminal. picture 5: Releasing plug terminal o Raise release lever (6) as described in illustration and pull out connecting wire (picture 5).

6.2 Troubleshooting

The device switches the load off briefly and then on again.

Cause: short-circuit protection has tripped but now there is no longer a fault.

AC 230 V ~

50 / 60 Hz

+5 ... +25 °C

1.0 ... 2.5 mm² max. 100 m

The device switches the load off and cannot be switched on again.

Cause 1: short-circuit protection has tripped.

Eliminate short-circuit. i Short-circuit protection is not based on a conventional fuse, no metallic separation of the operational current.

Cause 2: overheating protection has tripped.

Disconnect dimmer from mains, also switch associated off circuit breakers.

Let dimmer cool down for at least 15 minutes.

Reduce the connected load.
