Frequently Asked Questions - LS1565.07 JUNG

Can I use the JUNG LS1565.07 dimmer with all types of LED bulbs?

Only with dimmable LEDs. Check the bulb packaging for 'dimmable' mark. Non-dimmable LEDs will flicker or may be damaged.

What is the maximum load for incandescent bulbs?

The maximum load is 400 W for incandescent or halogen bulbs.

What is the minimum load for LED bulbs?

The minimum load is 5 W for LED bulbs to ensure proper dimming.

Does the dimmer require a neutral wire?

No, the JUNG LS1565.07 is a two-wire dimmer and does not require a neutral connection.

How do I install the dimmer?

Installation must be performed by a qualified electrician. Turn off mains power, connect the live wire to L and the load wire to the arrow symbol, then mount into a flush box.

Why does my dimmer feel warm to the touch?

A slight warming is normal due to the built-in triac. If it becomes very hot (>60°C), reduce the load or check for ventilation.

Can I use the dimmer with a fan or motor?

No, the dimmer is designed for resistive and capacitive loads only (incandescent, halogen, dimmable LED/CFL). Motors or inductive loads may cause damage.

The light flickers at low dim levels. What should I do?

Ensure you are using dimmable LEDs and that the total load is above the minimum. If problem persists, try adjusting the minimum brightness trimmer on the device (if available) or replace with compatible bulbs.

How can I clean the dimmer?

Wipe the surface with a soft, damp cloth. Do not use abrasive cleaners, solvents, or water sprays.

What is the warranty period for the JUNG LS1565.07?

JUNG offers a 5-year warranty from the date of purchase. Proof of purchase is required.

Operating instructions

1 Safety instructions

Electrical equipment may only be installed and fitted by electrically skilled persons.

Serious injuries, fire or property damage possible. Please read and follow manual fully.

Danger of electric shock. Do not operate the device without a cover.

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.

Exchange defective load on output a1 immediately, because the overheating protection is no longer provided when the load is defective. 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 load up to the specified output (see chapter 6.1. Technical data)
• Suitable for luminaire groups via the two independent outputs a1 and a2
• Installation in appliance box to DIN 49073
• Operation with suitable cover (see chapter 6.3. Accessories)

i No mixed-load operation of Tronic and inductive transformers on the same output.

Product characteristics

• 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)
• Different load types are possible on the two outputs
• Asymmetric load distribution possible
• Automatic setting of the dimming principle suitable for the load
• Connection of more than one 2-wire extension is possible (see Accessories section)

i The connection of installation buttons as extensions is not possible. This will not function.

Load type Electrical behaviour Dimming principle
Incandescent lamps ohmic Phase cut-off
HV halogen lamps ohmic Phase cut-off
Tronic transformers with halogen lamps	capacitive Phase cut-off
Dimmable inductive transformers with halogen lamps	inductive Phase cut-on

i Flickering of the connected lamps due to undershoot of the specified 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

a1 a2

Figure 2: Operating sections of the button

The button field is subdivided into two areas:

- Left: operation of output a1.

- Right: operation of output a2.

i A 2-wire extension is always used to operate both outputs simultaneously.

Switching on the light

■ Press button at top for less than 0.4 seconds.

i The light is switched on using the stored switch-on brightness.

Switching the light off

■ Press button at bottom for less than 0.4 seconds.

Adjust the brightness

Light is switched on.

■ Press up or down button until the desired brightness is reached.

Switching the light on with minimum brightness.

Light is switched off.

■ Press button at bottom for longer than 0.4 seconds.

Save switch-on brightness

Separate switch-on brightnesses can be saved for outputs a1 and a2. In the state as supplied the maximum switch-on brightness is saved.

Light is switched on.

■ Set light to the required brightness.
■ Press button for longer than 3 seconds.

Switch-on brightness is saved.

The lighting switches briefly off and on again as confirmation.

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.

CAUTION!

Do not connect outputs together.

Operating both outputs on a common load will destroy the device.

For power extension use power boosters

CAUTION!

Electronic overheating protection only with active output a1.

Operation without electronic overheating protection can destroy the device.

Never operate output a2 alone.

Connecting and mounting the dimmer

(5) 2-wire extension

(6) to additional extensions

i Output a1 can also be operated alone.

Pay attention to load distribution when an output is loaded with more than 260 W/VA(see chapter 6.1. Technical data). Determine intermediate values by means of interpolation.

■ Connect the dimmer according to the connection diagram (figure 3).

■ 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.

■ Mount the dimmer in an appliance box. The terminals must be at the bottom.

■ Attach the frame and the cover.

6.2 Troubleshooting

Operation via extensions is not possible.

Output a1 not connected correctly.

Check installation.

Defect load on output a1.

Check load on output a1.

Device switches both outputs off and can only be switched on again after a certain time.

Electronic overheating protection has tripped

Reduce the connected load.

Check the installation situation.

Electronic overheating protection only functions when a load is connected to output a1. No automatic switch-on after cooling.

Device switches and output off briefly and then on again.

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

Or: The device switches one or both outputs off and cannot be switched on again.

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.

Dimmer is defective and has been disconnected from the mains permanently by internal fuse.

Exchange dimmer.
