Frequently Asked Questions - 824TDW JUNG

What types of lamps can I use with this dimmer?

This dimmer is designed for incandescent lamps, HV halogen lamps, and Tronic transformers with halogen lamps. Do not use electronic lamps, dimmable energy-saving lamps, or LED lamps.

Why does the light flicker?

Flickering may occur if the connected load is below the minimum specified load (20 W) or due to centralised pulses from the power station. This is not a defect.

How do I switch the light on/off?

Press the control button briefly to switch the light on or off.

How do I adjust the brightness?

With the light on, turn the control button clockwise to increase brightness, or anti-clockwise to decrease it.

What is the control output A used for?

Control output A provides a switching signal (max. 100 mA) to control an external automatic power disconnection or relay. It cannot be used as a load output.

Can I use this dimmer with inductive transformers?

No, operation with inductive transformers is not allowed. Only Tronic (electronic) transformers are supported.

What happens if there is a short circuit?

The electronic short-circuit protection will switch off the load within 7 seconds. After eliminating the short circuit, press the control button twice to reset.

Why does the dimmer turn off and on again after some time?

This indicates the over-temperature protection has activated. Reduce the connected load or improve ventilation. The device will automatically turn on again after cooling.

Can I install two dimmers for changeover switching?

No, two dimmers cannot be used together. Use one dimmer and an external changeover switch according to the connection diagram.

How do I clean the dimmer?

Wipe the surface with a dry cloth. Do not use any cleaning agents or water.

Operationsmanual

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.

Do not connect electronic lamps, e.g. switchable or dimmable energy-saving lamps or LED lamps. Otherwise the possibility of a device defect cannot be ruled out.

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

3 Function

Intended use

• Switching and dimming incandescent lamps, HV halogen lamps and 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 operation with inductive transformers.

Product characteristics

• Dimming principle, phase cut-off.
• Soft locking on operation
• Electronic short-circuit protection with permanent switch-off after 7 seconds at the latest
• Electronic over-temperature protection
• Changeover switching possible in combination with changeover switch
• 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. This does not represent any defect in the device.

4 Operation

Switch light

■ Press the control button.

Adjust the brightness

Light is switched on.

■ Turn the control button in the clockwise direction.
The light gets brighter up to maximum brightness.
■ 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 carrying out work on the device or load, disengage all the corresponding circuit breakers. Cover up live parts in the working environment.

The symbols used to label the dimmer load shows the load type that can be connected to a dimmer and the electric behaviour of a load:

R = ohmic, C = capacitive

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 briefly and then on again.

Short-circuit protection has tripped but now there is no longer a fault.

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

Short-circuit protection has tripped.

Eliminate short-circuit.

Switch the dimmer back on by pressing the control knob twice.

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