Dimming information

 

General

The dimmable LED luminaires have a "D" in the last position in the model designation. For this purpose, the LED luminaire has an LED driver (constant current source) with integrated dimming function, which can be addressed via a control line. In addition to the assembly and installation instructions, we have summarised further explanations on the dimming of the luminaires here. Please also be sure to read the assembly and installation instructions, which are enclosed with the luminaire or can be downloaded from our website.

 


Safety instructions

August Müller Lichttechnik AG accepts no liability for damage or consequential damage caused by failure to observe these instructions or by improper assembly, installation or handling of the luminaire.
■ Disconnect the power supply before carrying out any work on the luminaire.
■ The installation of this luminaire involves work on the mains voltage; it must therefore be carried out professionally in accordance with the country-specific installation regulations and connection conditions.
■ Do not look into the luminaire from a short distance or for a longer period of time (> 5 min.). This may cause damage to the retina.


Selection of the dimming method

The brightness of the light can be adjusted by a 1 - 10 V DC control voltage, a 10V PWM signal (pulse width modulation) or by resistor on the control line. We recommend the use of the 1 - 10 V DC control voltage, as this is a very proven dimming method and a large number of accessories are commercially available.


Connection

Depending on the model, the control line consists of a separate 2-core cable or the 2-core control line is routed out of the luminaire parallel to the 3-core mains supply line in a 5-core cable. For more information, please refer to the respective mounting and installation instructions.

It is essential to observe the correct polarity of the control line. First check the function of the dimming for a short moment. If dimming is not possible, immediately disconnect the luminaire from the power supply and check or replace the polarity.

IMPORTANT! Never apply mains voltage to the control line. This will lead to a defect of the luminaire or the LED driver.

■ The control line must be connected to the fixed sheathed cable in a fixed junction box (e.g. on the roof beams).
■ For an extension of the control cable we recommend insulated butt connectors (e.g. Klauke Art. 680) with a sheathing of the connection point with heat shrink tubing or a plug-in connection (e.g. Wieland Gesis RST 20i3).
■ Only if dimming is desired, remove an existing protective cap from the control line or remove the insulation from the cable ends. A short circuit on the control line leads to dimming of the luminaire.

 


Dimmer switch for 1-10V DC control voltage

We recommend the use of the 1 - 10 V DC control voltage in conjunction with the following dimmer switches for dimming the luminaire, with which both dimming and switching of the luminaire is possible.

■ The manufacturer's specifications for the switching capacity and power at the control output of the dimmer switch must be observed.
■ If required, the switching capacity can be increased by an additional Circuit breaker be increased.
■ The power consumption of the control line is 0.1 mA per luminaire of all series (except PA).
Taking into account the aforementioned power values, a correspondingly large number of luminaires can be used. parallel be connected to a dimmer switch. With long distances, line resistances can lead to different dimming

Examples of lighting control in conjunction with bus system/building automation

connection with KNX bus
Hager Switch/Dim actuator 3-fold TX211A : 1-10V
GIRA control unit 1-10V 4-gang, order no. 2224 00

With these control units you can dim and switch one or more of our luminaires in up to 4 circuits via a KNX bus. In addition, manual switching is possible for each circuit.

The KNX bus is a worldwide standard for the Building automation respectively smart home and enables the integration of sensors, for example.

DALI- Interface module (gateway)
Lunatone DALI RM8/RM16 for 1-10V or PWM signal
Lunatone wDALI RM8 for 1-10V or PWM signal (radio)

With this interface module you can dim and switch one or more of our luminaires via a DALI interface.

The DALI interface enables digital networking and control of lighting systems
