1 Introduction

1.1 Dimmable lighting systems Dimmable electronic control gears (DIM ECGs) are playing an

increasingly important role in all areas of application of modern lighting technology. Dimmable ECGs from OSRAM, integrated in a building management system, form the heart of intelligent lighting systems which save up to 80 % of energy compared to conventional electronic control gears. The reason for this is that many requirements of a lighting system are simple and elegant to realize by means of light control. Economy, lighting comfort, reliability and safety are the driving forces here.

1.1.1 Economy

Intelligent energy-saving concepts in building management lower the

lighting costs many times over:

• Up to 50 % less power consumption compared to operation with magnetic, conventional electronic control gears (CCG)

• More than 50 % longer lamp lifetime compared to operation with ECG and low-loss electronic control gears (LLG) through defined lamp operation ! Lower maintenance costs

• Lowering of energy costs for air conditioning systems by reducing the cooling load

Figure 1: Global energy saving potential with dimmable electronic

control gear

1.1.2 Lighting comfort

Lighting situations at the touch of a button (lighting scenes), also with

integrated presence detection and daylight/time-dependent control, increase lighting comfort. The features of a high-quality dimmable ECG also include:

• Flicker-free ignition

• Comfortable, continuously dimmable (1(3)…100 %) and flicker-free lighting without stroboscopic effects

• Virtually noise-free, no irritating humming of chokes (CCG/LLG)

• No flashing of defective lamps

• Automatic restart after lamp replacement

• Easy-to-use, feedback messages to the control unit and configuration of personal lighting values create individuality

Figure 2: Energy saving and increased lighting comfort through inte-

grated presence detection with daylight/time-dependent control

This has been made possible mostly thanks to technical develop-

ments. Modern dimmable ECGs with digital (DALI = Digital Address- able Lighting Interface) or analog (1…10 V) interface in combination with corresponding control elements, control units and sensors create the preconditions for simple and low-cost realization of more efficient and convenient lighting systems.

1.1.3 Reliability/Safety

•

Reliability and safety play a crucial role in the use of electronic control

gear. Key features of high-quality ECGs include:

• Preheating of both lamp filaments

• Dependable lamp ignition to an ambient temperature of -20 °C

• Dependable lamp operation in the temperature range of -20 °C to

75 °C

• Dependable shutdown of the ECG in the event of a fault and at "End of Life" (EoL)

• Compliance with all current applicable ECG standards:

• Safety (EN61347)

• Performance (EN60929)

• Harmonic current emissions (EN61000-3-2)

• Radio interference suppression from 9 kHz to 300 MHz

(EN55015: 2006 + A1:2007)/CDN measurement

• Immunity (EN61547)

1.1.4 The right control unit for every application

Dimmable ECGs have a very wide range of uses. Some examples of

applications are offices and industrial buildings with light-dependent control, conference and assembly rooms with lighting for the particular situation or CAD offices and switch rooms with individually adjustable light levels. The core of the lighting system are the dimmable QUICKTRONIC Intelligent

ECGs from OSRAM with DALI or 1…10 V interface (QTi DALI/DIM) for the operation of compact and fluorescent lamps. These are controlled by a control unit, a sensor or a simple button/rotary dimmer switch. The choice of the right dimming components for controlling the lighting depends on the desired application. The requirement profile of the dimmable lighting system must, therefore, be defined in detail.

• EMC filter for HF interference signals from 9 kHz to 300 MHz

2.2 DALI in comparison to 1…10 V and EIB/LON What modern lighting technology needs is a system that is as flexible

as it is simple, a system that focuses on room-based lighting control with just a few low-cost components, minimal wiring and a user-friendly operating concept. The lighting industry has therefore developed a new digital communication standard for lighting systems:

DALI closes the gap between the former 1…10 V technology and

complex bus systems. DALI can be used either as a very simple local solution or as a subsystem integrated in a building management system.

Figure 4: Overview of 1…10 V, DALI and EIB/LON

With traditional electrical installations and even with the widely used

analog 1…10 V interface such requirements are very difficult to meet and involve a great deal of time, effort and expense. A large number of components have to be used to enable a programmed scene to be changed, to provide flexible grouping at the same time and then possibly to integrate these settings in a daylight-dependent control system.

2.2.1 DALI and 1…10 V characteristics The basis for any control system are the defined physical proper-

ties at the interface and the properties of the interface cables as the transmission medium. Thanks to a high signal-to-noise ratio and wide ranges for digital “low” and “high”, it is virtually impossible with DALI for data transfer to be affected by interference. Consequently, there is no need to use shielded control cables. As in the case of the 1...10 V interface, the mains and control inputs in the ECGs are electrically isolated. A conscious decision was taken not to use safety extra-low voltage (SELV) in order to offer low-cost installation without additional

special lines or cable penetrations. A 5 x 1.5 mm2 NYM cable, for example, can be used for the mains feed and DALI.

2.3 DALI installation & features

2.3.1 Simplified installation The installation of DALI is carried out with commercially available in-

stallation material for 230 V line voltage. The two wires of the five-wire cables (e.g. NYM 5 x 1.5 mm²) that are not needed can be used for the DALI interface - regardless of polarity. Thus, no separate bus cable is required! The ECG and control unit line voltage phases.

2.3.2 Construction site mode

The ECGs can be switched on or off at any time via the fuse protec-

tion even if there is no controller installed or programmed (basic DALI function). With ECGs straight from the factory the lighting is always switched on at 100 % luminous flux.

2.3.3 Benefits of DALI ECG with group assignment Each ECG in the DALI system can be addressed individually and digi-

tally. Each ECG is assigned an address and group association on start-up. Each ECG may belong to as many as 16 groups – and to several groups at the same time. The ECGs can be addressed individually, in groups or all together. The group assignment can be changed at any time without rewiring.

can be operated on different

2.3.4 Integrated scene memory Each ECG can store up to 16 light values, irrespective of the group

assignments. Fading from one scene to the next is synchronous. This means that all ECGs start fading to the new scene at the same time and finish at the same time (by varying the dimming rate).

2.3.5 Status report from the ECG The control unit can query the status of each and every ECG. This

enables a lamp fault (or failure) or the brightness of a lamp to be determined, for example. The feedback capability of the OSRAM DALI ECG is crucial in association with complex bus systems (EIB, LON) in building management systems (e.g.: the OSRAM BASIC checks for lamp faults and can forward these via a potential-free message contact; the OSRAM Advanced provides the option of analysis by of the HPT (Hand Programming Tool, see www.osram.com/ecg-lms)

means

2.3.6 No more switching relays The ECGs are switched on and off via the interface. The

nal relays required for switching are therefore no longer

former exter-

needed.

2.3.7 Addressing is not essential DALI can also be used without any addressing (groups or individual

addresses). A method known as broadcast mode is used here, which simply means that all control units are addressed together.

2.4 Installation and wiring instructions

2.4.1 Burning-in instructions/Cable insulation

• For forming and basic stabilization new lamps must be burned in

for 100 hours at 100 % dimmer setting (undimmed). Interruptions during the burning-in are permissible. In dimming operation without burning-in this can result in the lamps flickering, premature endblackening and shorter operating life. For measurements based on IEC 60081, the lamps must also be correspondingly burned in, in order to achieve maximum luminous flux and optimum lamp stabili-

ty.

• Dimming is generally only possible with filament preheating. The

filament temperature must be kept constant by auxiliary heating as this can to lead to effects such as tungsten depletion (sputtering) or to elevated vaporization of the emitter material.

• The control input (DALI or 1…10 V) is insulated from the mains

(230 V voltage-proof) by basic insulation (not SELV). The mains cable and control line can therefore be routed together in a 5-core NYM cable.

! Solution: Intermediate reaction due to carbonate compounds from which the oxides are formed

The electrodes of a low pressure discharge lamp are coated with an emitter (barium, strontium and

calcium oxide) to reduce the work function of the electrons from the tungsten filament wire. These oxides are strongly hygroscopic and interact with the humidity of the air (consequence: relatively low light yield, high lamp voltage and short service life of the lamp)

at temperatures above 600 °C. The actual reduction of the filament work function requires atomic barium on the emitter surface, which is only fully formed at the max. dimming setting (100 % luminous flux) and high temperatures (1900 K electrode temperature) over a time period of 100 h. If these conditions are not fulfilled, an increased cathode voltage drop results and leads to material deposits on the filament: Reduced service life

In accordance with DIN VDE 0100 Part 520 Section 528.11, main current circuits and associated

auxiliary circuits can be laid together, even if the auxiliary circuits carry a lower voltage than the main current circuits.

Note (acc. to DIN VDE 0100/11.85, T 520, Sect. 528.11):

•

• Cables or lines that are insulated for the maximum operating

voltage must be used, or each conductor of a multi-wire cable/ line must be insulated for the next voltage appearing in the cable/line.

• When laying conductor lines in electrical installation pipes or

ducts only the conductors of a main power circuit including the associated auxiliary power circuit may be laid together

• Several main power circuits including the associated auxiliary

power circuits can also be combined in a single cable or line

• Cables and terminals approved for use the mains voltage (230 V)

must be used for the installation

• The installation must be carried out in such a way that when the

supply voltage is switched off, all signal and control cables are also switched off at the same time

• All components of the main power and control power circuits must

be designed for 250 V working voltage to ground

• All the luminaires must be wired with H05 cables provided U

does not exceed 430 V

and also be subjected to an insulation

2.4.2 Safety instructions

Electronic control gear should be installed and maintained by qualified

electricians only

Disconnect electronic control gear from the power supply before

maintenance work

Use indoors only

2.4.3 Radio interference suppression of dimmable luminaires The use of dimmable ECG is only approved in luminaires of protection

class I (PC I) as only here is adequate grounding assured.

Note:

When dimming, the operating frequency of the lamp and the lamp

burning voltage increases at the same time which can lead to elevated leakage currents. Leakage currents emerging from the lamp always flow back into the ECG because the current circuit must be closed. To keep cable-related interference as low as possible, the leakage current is offered a different return path, the ground conductor (=casing) and the PE connection of the ECG.

In brief: Dimming is not possible without grounding. Dimmable ECGs

only function in PC I luminaires and not in PC II luminaires as these have no protection contact. Connecting the dimmable ECG to the functional ground is not permissible.

Figure 5: Protection class I luminaires

The maximum 50 Hz leakage current of the ECG via the ground fault

circuit interrupter (FI switch) is 0.5 mA.

• Mains cables and control lines may be routed together and should

be laid close to the luminaire wall

•

Mains and control cables must not be laid close to the lamp cables

• If crossovers of mains and lamp cables are unavoidable, they

should cross perpendicularly

• Do not lay the PE conductor together with the lamp cables

• Do not use shielded lamp cables (reduction of capacity leakage

currents)

• The OSRAM DALI/DIM ECG must always be installed near the

lamp(s) so that the lamp cables can be kept short in the interests of good radio interference protection

Notes:

•

• Max. lamp cable length of the "hot end" (higher potential to

ground): T5, T8: 1 m/T4: 0.5 m

• Excessively long lamp cables cause the following problems:

- Poor radio interference suppression

- Uncertain lamp detection (not in T8)

- Poor synchronization of 2-lamp OSRAM DALI/DIM ECGs

• Lay the lamp cables close together and close to the lamp

• Lamp cables must not be laid in metal pipes and must not be

shielded cables

• Guide the cables of the different lamp ends separately

• In the case of multi-lamp OSRAM DALI/DIM ECGs, the cables to

the respective lamp ends must be of the same length to prevent differences in the brightness

• When dimming florescent lamps the maximum lamp voltage is

reached at the lowest dimmer setting (3 %-10 %) due to the negative current-voltage characteristic

Note:

• Maximum capacitance of a filament cable pair to ground: T5: 75 pF T8/DL: 150 pF

• Maximum capacitance between "hot" and "cold": T5: 15 pF T8: 30 pF

2.4.4 Operation of multiple ECGs in a luminaire If several dimmable ECGs are operated in a luminaire, there can be

interference effects and hence to flickering, jerky dimming or even to shutdown of the ECGs if they have not been correctly installed. The cause for this are inductions between the lamp current circuits of several ECGs: If a lamp running at 100 % transfers just 1 % of its current into the neighboring lamp dimmed to 1 %, this represents a fault of 100 %. The same applies to coupling between a heating current circuit, i.e. feed and return lines to one side of the lamp and the neighboring lamp circuit.

There should, therefore, be a minimum spacing of 12 cm between the

lamp circuits (lamp and cables) of different ECGs. If this is not possible, the lamp wiring must be carefully installed so coupling between the lamp circuits is reduced to a minimum:

• Lay the lamp cables close to the appropriate lamps so that the

area covered by the lamp circuit is as small as possible. The lamp circuits of the two ECGs must not overlap. This is particularly important for color control if adjacent ECGs are dimmed to different levels.

• There should be a spacing of several centimeters between the

lamp cables of two ECGs

• The "short" (hot) lamp cables (see also ECG imprint) should lead to

one side of the lamp and should be as short as possible. The "long“ (cold) lamp cables to the other side of the lamp (see Table 2)

• Mains and control cables should not be laid close to the lamp ca-

bles (prevents undesired couplings into the control cable)

• All the mains and control cables may be routed together. To ensure

that radio interference suppression is not impaired, there should be a gap of several centimeters to the lamp cables.

The better these recommendations are implemented, the more stable

is the light at the lowest dimmer setting, even with a very small lamp spacing – and, hence, the full temperature range of the ECGs can be used.

• In the "worst case" twist the cables of the heating circuits together,

hence ensuring they lie close together. With 1-lamp ECGs these are the 21-22 and 26-27 cables, with 2-lamp ECGs; 21-22 and 21-23, 24-25 and 26-27. This is particularly important if adjacent ECGs are operated at the lowest dimmer setting (1(3)%).

If there still are problems: Remove all lamps except for the most

"problematic" ECG – this will eliminate possible faults from the other lamps. If the lamp then works correctly over the entire dimming range, the decoupling measures for the other lamps (cables) are still not adequate.

2.4.5 Wiring examples of dimmable electronic control gear

Figure 6: Three 1-lamp ECGs

Correct: Wrong:

The lamp lines are laid close to the respective lamps. There are no overlapping lamp current circuits. The “hot" side is up and the “cold" is down.

The lamp lines of all ECGs are laid together, also overlapping lamp current circuits are formed in this way.

Figure 7: Three 2-lamp ECGs

Correct: Wrong:

The lamp lines are laid close to the respective lamps. The overlapping of the three right lamp current circuits is minimized.

Note: T5 florescent lamps must be used so that the lamp stamps are on

the same side. The lamp stamp must be underneath (Cold Spot) in the upright burning position. If this is not the case, the lamp parameters will fluctuate which can lead to unstable burning behavior of the lamp.

2.5 The DALI interface – technical details DALI defines the digital communication between a control unit with

DALI interface and a DALI controller (ECG). The detailed specifications of the DALI interface can be found in IEC 62386.

The lamp lines of all ECGs are laid together, also overlapping lamp current circuits are formed in this way.

2.5.1 The DALI system principle Each control unit works as a "master" and controls communication on

the control cable. ECGs, in contrast, may only respond as a "slave" to a request of the "master".

DALI relies on consistent intelligence distributed throughout the

system, an intelligent control unit communicates with intelligent components. For example, the control unit only issues the command: "Scene 1" and the processor in the ECG adopts the desired light value. This way all ECGs achieve the set value at the same time.

2.5.2 DALI topology

•

The DALI ECGs are wired in parallel to each other and groups are not

taken into consideration. Star configurations are also possible. Ring wiring is not permitted (indicated by X in the diagram). There is also no need for terminating resistors on the communication cable.

Figure 8: DALI topology

2.5.3 DALI parameters in the ECG The following data can be stored in the DALI ECGs when a DALI

system is started up:

• Group assignment of the DALI ECG (max. 16 groups, multiple

assignment is possible)

• Individual address for accessing each ECG directly (max. 64)

• Lighting values for the individual scenes (max. 16)

• ECG parameters that determine the behavior of the ECG:

• Dimming rate

•

• Behavior when the mains voltage is restored (Power On Level)

Behavior if the voltage fails on the interface (System Failure Level)

In addition to the above-mentioned options, it is always possible to

address all the devices together, even without programming the devices beforehand (construction site function).

2.5.4 Requirements to be met by the transmission cable When selecting a cable make sure that the voltage drop on the line

does not exceed 2 V at 250 mA. As with 1…10 V systems, the power supply and control line can be run in the same cable. This means, for example, a 5-core NYM cable can be used to connect the DALI ECG without any problems. The maximum permitted total length of cable between the controller and the connected ECG is 300 m.

Cross section of the power cable:

A = L x I x 0.018

A = Line cross section in mm², L = Cable length in meters,

I = Max. current of the supply voltage in A,

0.018 = Specific resistance of copper

The following formula is used as a basis for finding the cable cross

section (transmission and power cable):

Line length Line cross section

up to 100 m 100 to 150 m 150 to 300 m

0.5 mm

0.75 mm

1.5 mm

Note: Because of the different technical properties of the DALI interface in

control units found on the market and the differing local conditions of the installation, it is recommended to limit the overall line lengths used in the system to 300 m.

With DALI, data telegrams are produced by short-circuiting and re-

leasing the line in order to generate the corresponding "low" or "high" logic states. This may be caused by either the ECG or by the controller. In the event of a short-circuit the current is limited by the interface supply to 250 mA. In the idle state (no data transfer) approx. 16 V on the ECG. The following figures illustrate data transfer via DALI:

Data is transferred using the Manchester code. The signal edges in

the middle of the bit carry the information here. A trailing edge indicates a logical zero and a rising edge a logical one.

2.6.1 Behavior in the event of a fault If there is no power at the DALI interface (controller faulty or switched

off), the System Failure Level is set. The Power On Level is activated after a mains voltage failure (230 V). The System Failure Level has the higher priority.

Both values are set at the factory to 100 % luminous flux, but can

be individually programmed with the Dali Luminaire Tool (DLT) from OSRAM, for example.

2.7 The DALI dimming curve IEC 62386 defines the dimming range of a DALI controller from 0.1 to

100 %. The dimming curve is shown in the graphic below. As far as the eye is concerned, this categorization is a linear response

accord-

ing to the Weber-Fechner Law.

The Weber-Fechner law states that the subjective strength of sensory stimuli is

logarithmically related to the objective intensity of the physical stimulus.

Table 3: Values of digital dimming value against percentage luminous

As not all DALI controllers start at 0.1 % luminous flux, the smallest

value for DALI ECG is 85 for example (corresponds to 1 % luminous flux). All values below 85 (except for 0 = off) are interpreted as the minimum light level. To ensure that the transitions from one digital level to the next are not visible, DALI ECGs from OSRAM feature digital “smoothing" (this is an additional function of the QTi for increasing lighting comfort and is not part of the DALI standard).

2.8 Features of the digital interface

• IEC 62386 – This allows the combination of units from different

manufacturers. A special feature to be noted is that the DALI man- ufacturers represented in the AG DALI.

test their units together in

order to guarantee high functional security.

• Physical usable data rate of 1200 bit/s enables fault-free opera-

tion

• Safe interference voltage gap – the generously dimensioned inter-

ference voltage gap of the high and low level guarantee safe operation

• Data coding – the Manchester code is used; its structure allows

detection of transmission errors

• Maximum system current – the maximum current that a central in-

terface

supply must deliver is 250 mA. Each control unit may take max. 2 mA. This must be taken into consideration when selecting the interface supply.

• Limited system size – a maximum of 64 control units with an in-

dividual address can be operated differently in a single system

• Feedback of information – ON/OFF, current brightness value of the

connected lamps, lamp status etc. are possible

• Two-wire control line – there should be two basic insulations be-

tween two conductors. Hence, single-layer insulation of a conductor is adequate. Control and supply lines can be laid together; a minimum cross section of the line must be maintained here. The maximum line length between two connected system subscribers must not exceed 300 meters

• Potential-free control input – the control input is electrically sepa-

rated from the mains supply. The ECGs can thus be operated on different outer conductors (phases)

• No terminating resistors required – the interface lines do not need

to be connected to resistors

The DALI interface of the control unit also supplies the DALI interface of the

connected DALI components. To ensure that the total current of max. 250 mA permitted for DALI is not exceeded, no other DALI supplies or DALI controllers can be connected to this system. In order not to exceed the max. permissible voltage drop of 2 V on the interface lines, the line cross section must be chosen according to the table in the technical details (2.5.4).

• Dimming range 1 %…100 % (the lower limit depends on the lamp

and manufacturer). The progression of the characteristic is standardized and adapted to the sensitivity of the eye (logarithmic characteristic). Because of the standardization, a similar sense of brightness is achieved when using control units from different manufacturers

• Programmable dimming times – special settings such as light

change speeds (e.g. from 1 % to 100 % dimmer setting) are possible

• Disconnection of the data line – the specified light values are ad-

opted automatically

• Storage of light scenes (different group-dependent dimming states)

– up to 16 scenes can be stored

• Connection via converter to building management systems – the

interface is primarily conceived for room applications; it can be integrated into building management systems via gateways

• Simple system reconfiguration – once the system is set up and

configured, changes of the system function, the light scene and light functions are only a matter of configuration and do not require any changes to the hardware. Example: Regrouping of luminaires in a large office building

• Simple integration of new components – if an existing illumination

system is to be extended, new components can be added anywhere within the system. Attention must be paid here to adequate dimensioning of the system supply

• Polarity freedom of the interface

2.9 Characteristics of the 1…10 V interface Note: This chapter is based on OSRAM ECGs types QTi DIM and HF DIM,

abbreviated to OSRAM DIM ECGs in the following

• Control is carried out via a fail-safe DC signal of 10 V (maximum

brightness; control line open) to 1 V (minimum brightness; control line shorted)

• The control power is generated by the ECG (max. current: 0.6 mA

per ECG)

• The voltage on the control line is voltage-insulated from the mains line (basic insulation), but there is no safety extra-low voltage

(SELV)

• ECGs in different phases can be dimmed by the same controller

Note:

•

Due to the characteristics of the 1…10 V interface, the following must

be noted:

• All control lines of an ECG installation must be connected with the right polarity (+/-)

• The control line is voltage-insulated from the mains line but there is

no safety extra-low voltage (SELV). Therefore, cables and terminals that are approved for supply voltage 230V must be used for the installation

• The control voltage is simple to limit upwards or downwards with resistors; several control units can be combined with one another

• The correct function of the ECG can be tested as follows:

• Switch-on of the ECG with open control line. The lamp must

ignite and burn with max. luminous flux

• Switch-on of the ECG with shorted control line (wire jumper).

The lamp must burn with min. luminous flux

• Each OSRAM DIM ECG can be used as a normally non-dimmable ECG if there is no control unit connected to the control line

• The dimmable ECGs are only dimmed via the 1…10 V interface and switched via the mains line

• The maximum load capacity of the control unit (switched output and 1…10 V output) must be heeded

• The connected control unit must always be able to handle the cur- rent supplied in the control line by the ECG (current sink) and to reduce the control voltage. This precept is fulfilled by accordingly dimensioned potentiometers as well as by all OSRAM control components. Normal power supplies, converter boards etc. do not necessarily have this characteristic! To check, connect the control unit, set to the lowest brightness and measure the voltage on the control line. The set value is 1V or less

• OSRAM DIM ECGs cannot be dimmed via the mains line (e.g. with phase control mode, round control pulses etc.)

2.9.1 The 1…10 V dimming curve

The 1…10 V interface is defined in IEC 60929. In the control voltage

range of 3 V tive luminous flux. In the 1…10 V interface, a logarithmic response (like the DALI units) is adjusted by a logarithmic potentiometer.

The control current in the 1…10 V interface drops with increasing

control voltage. Unlike the DALI interface, this does not therefore remain constant.

• Automatic lamp detection through intelligent multi-lamp operation

(reduction of the ECG type variety)

Lamps of the same length and different powers can be operated

on an ECG. Furthermore, there are special approvals for specific ECG lamp combinations

• Dimming range to 1 % of the rated luminous flux (3 % in CFL)

• Ignition of the lamp at an ambient temperature of -25 °C

• Optimized lamp warm start within 0.6 s [including HF DIM]

• Temperature-dependent “cut-off” at dimmer settings > 80 %

Shutdown of the filament heating at dimmer settings > 80 % pre-

vents a permanent heating current through the lamp electrodes during operation. This reduces the filament loading and the power loss by approx. 2W

• Power reduction by the ECG at excessively high ambient tempera- tures in order to protect the electronics ! Can be used in very close, hot luminaires (operating life, increased light yield, simplified safety approval)

• High T temperatures (T

point values (Tc < 80 °C) enable operation at high ambient

values)

• Stable dimming operation also in amalgam lamps (CFL (IN) and OSRAM T5 CONSTANT lamps) ! particularly suitable for use in areas with low ambient temperatures (e.g. cool rooms, outdoors): relative luminous flux > 90 % from 0 °C to 70 °C

• Intelligent power control upon detecting instabilities in the lamp circuit (amalgam lamp start) – protects lamp/ECG

• Permanent Heat Mode (PHM) for lighting effects (permanent fila- ment heating, switch-on of the continuous lamp pre-heating by digital command, not DALI standard): The PHM ensures that, at a light value = 0 (switched off lamp(s)), the lamp electrodes are already heated. A delay-free lamp start is therefore possible

• 0.5 s < t < 1 s on/off switching cycle in the PHM ! 30 k

3.2 OSRAM DALI ECGs and TouchDIM interface

To realize light controllers as economically as possible, the DALI ECGs

from OSRAM also have the integrated TouchDIM function

. It is there-

fore possible to dim and switch DALI ECGs directly with mains voltage on the DALI control terminals (TouchDIM Interface = TDI). Only one commercially available switch is required, the ECG assumes the control function.

The changeover between both operating modes – TouchDIM or

DALI operation – can only be realized after mains voltage. Hence, it is not possible to switch between the operating modes via an integrated safety mechanism during operation. Switching between both operating modes can take place as often as necessary. TouchDIM must never be used at the same time with a DALI control system.

TouchDIM offens all the functions of a comfort dimmer:

• Soft starting of the lamp (lamp starting at the lowest dimmer setting (1 % (3 %), lowest luminous flux)

• Short press: On/Off

• Long press: Dimming

• Memory function (light value stored by double-clicking)

• All settings are remained even after a power outage

TouchDim is not part of the DALI standard

3.2.1 Wiring and line compensation

• The line lengths between buttons and the farthest away DALI ECG

should not be longer than 25 meters. Where line lengths over 25 meters are required, compensation methods (bell transformer, resistor) must be used

• Do not use more than 6 DALI ECGs in one TouchDIM appli- cation (up to 6 ECG can be controlled by one switch, the number

of operating points is limited to 2)

• Different lamp families should not be mixed because of the different preheating times (e.g. HO lamps (500 ms starting time) vs. HE lamps (700 ms starting time)

• If more than one operating point is required, a maximum of 2 buttons per TouchDIM application can be switched in parallel

• The TouchDIM wiring must be rated for mains voltage (230 V)

Note:

• Only use switches without control lamp and with 230 V normallyclosed contact as the permanent current through the glow lamp can lead to malfunctions

• TouchDIM is not part of the DALI standard (IEC 62386), but rather an additional OSRAM function

3.2.2 Operating parameters for TouchDIM

To operate the TouchDIM, AC voltages of 10…230 V (RMS) at

a frequency of 46…66 Hz can be used – there is no DC voltage allowed.

3.2.3 Compensation of interferences

A control transformer which complies to the following figures and val-

ues must be used with a total line length from the switch to the ECG of 25 m to 100 m in order to prevent interference (e.g. through capacitive induction):

3.2.4 TouchDIM operation

• Switching the lamp on/off: Short button press (< 0.5 s)

• Dimming: Long button press (> 0.5 s), (dimming direction changes

each time the button is pressed)

• Save the reference value in the switched-on condition: "Doubleclick“ (press briefly 2 x within 0.4 s)

• Delete reference value: Double-click with the lamp switched off (ECG starts with 100 % luminous flux when switched on again)

Note:

Long button press with the lamp switched off: Lamp is switched on at

the minimum dimmer setting and, hence, remains highly dimmed until the switch is released.

3.2.5 Operating modes with TouchDIM

With the QTi DALI, OSRAM offers two modes for TouchDIM that dif-

fer in switch-on behavior (this refers to the software-controlled switching on/off and not to the switching off of the voltage supply):

Mode 1:

The electronic control gear switches with the last dimming value that

it had before being switched off. The following applies:

Short press: Switching Long press: Dimming/Switching on at minimum dimmer setting

For example: Vishay Beyschlag: MBA/SMA 0204, MBB/SMA 0207, MBE/SMA

0414 - Professional

Mode 2:

The electronic control gear switches on with the dimming value (pre-

set value) last stored by double-clicking. The following applies:

Short press: Switching Long press: Dimming/Switching on at minimum dimmer setting

The following figure shows the options of both operating modes to the

user:

3.2.6 Asynchronism/Automation of the system

The increased use of DALI ECGs in button operation shows again and

again that in systems with

• not completely sinusoidal supply voltage (e.g. electronic dimmer on

the same mains supply),

• excessively long line lengths or

• high DALI ECG count (more than 6 ECGs per TouchDIM applica-

tion)

increasing results in asynchronism of the connected DALI ECGs. To

consistently prevent asynchronously running lighting systems in practice, the permissible number of DALI ECGs is limited to 6 units.

3.2.6.1 Prevention/Remedying of asynchronism

With the aid of the DALI repeater that is described in more detail in the

context of the LMS (Light Management Systems) portfolio (see

www.osram.com/ecg-lms), up to 64 ECGs can easily be operated in the TouchDIM function without having to be concerned about asyn- chronism. Without the repeater, the TouchDIM application is however only restricted to floor-standing luminaires or small offices.

3.2.6.2 Synchronization

For physical reasons a TouchDIM can work asynchronously, i.e. the

switching status and dimming direction of the separate luminaires are different. The following steps help in the synchronization of a Touch- DIM system:

1st. step: Longpress (> 0.5 s)

! All luminaires switch on

2nd. step: Shortpress (< 0.5 s)

! All luminaires switch off

3rd. step: Longpress (> 0.5 s)

! All luminaires switch on and dim

4th. step: Double-click

! Save dimmer setting (if required)

Note:

TouchDIM was developed for manual control and is not suitable for

automation, e.g. for connecting to a PLC.

ECGs

3.2.7 Behavior after mains voltage failure

If the luminaire is disconnected from the mains, the ECG saves all

set values. If the light value has been changed before being switched off, this value is restored, i.e. after a voltage loss, exactly the last status is reestablished (instant switch-on to the previous present luminous flux, no "intermediate path" above 100 % luminous flux and subsequent dimming). All settings (dimming values, lamp on/off,…) also remain intact with a prolonged mains voltage failure. By doubleclicking, the stored reference value also remains in the ECG after a power failure and can, if required, be called up again with the luminaire on/off. If the luminaire was switched off at power failure, it also remains off when the mains voltage is restored. For this reason, operation in the TouchDIM mode is not suitable for centrally supplied emergency lighting applications.

3.3 OSRAM DALI ECGs in emergency lighting applications

Due to the variety of emergency lighting control systems and applica-

tions, this topic cannot be described in detail in this primer.

The integration and testing of the complete emergency lighting sys-

tem acc. to VDE 0108 must always be conducted by the persons responsible for the overall system as the ECG is only one element of the overall system. The VDE 0108 is a system standard and not an ECG standard. There are special electronic control units on the market for local emergency lighting applications with battery integrated in the luminaire. The instructions described here for wiring and programming the DALI controllers are based exclusively on central battery applications and, hence, on standard DALI controllers (ECGs).

QUICKTRONIC INTELLIGENT DALI ECGs are suitable for emergency

lighting systems based on VDE 0108. All OSRAM DALI controllers detect emergency operation (system failure level) if there is an absence of voltage on the DALI input (16V DC in normal operation). This function is part of the DALI standard and is supported by all vendors.

For emergency lighting/voltage loss13 in the DALI controllers two val-

ues can be configured/programmed separately for each unit (e.g. using the OSRAM DALI Luminaire Tool DLT).

• System failure level: Emergency operation (1…100 % light), detected by switching off the control line

• Power on level: Light value after the mains voltage is restored (1…100 % light)

The system failure level always has priority over the power on level,

especially when switching over (in the event of a brief power outage, emergency operation is therefore ensured). The factory setting for both values is 100 % light.

Typical data for the QUICKTRONIC INTELLIGENT DALI family impor-

tant for emergency lighting systems are*:

Starting time of the lamp (max.) 0.6 s Permissible voltage range (DC) 154…276 V Min. voltage for lamp start (DC) 198 V Permissible voltage range (AC) 198…264 V Mains frequency 0, 50…60 Hz

and DC operation.

DALI ECGs in emergency lighting management

The monitoring module (2) enables individual monitoring and control

of the DALI ECGs (1).

The following applies for normal operation: The OSRAM DALI ECG (1) emergency lighting is supplied with AC

voltage via the central battery system. All electronic control gear can be dimmed as usual and are controlled by the DALI controller (3). For maintenance functions (e.g. for servicing, caretaker switching) the OSRAM DALI ECG (1) emergency lighting can be switched to 100 % via the monitoring module (2), the commands of the DALI controller (3) (e.g. dimmer setting) are ignored.

A difference is now made between two cases when switching the

lighting system into emergency operation:

3.3.1 Mains failure at the subdistributor (UV)

In accordance with VDE 0108 when AC mains is present at the central battery system (CB) in emergency operation, the system must not be switched to battery but the security luminaires (1) must be switched to permanent light. The external DALI controller is ignored, the OSRAM DALI ECG (1) emergency lighting is dimmed to 100 % by the monitoring module (2) using a DALI instruction set.

3.3.2 Mains failure at the main distributor (HV) The central battery system (CB) provides DC supply voltage.

ternal DALI controller (3) is ignored, the ECG is dimmed to a previously defined value via a DALI instruction set. The emergency lighting level is pre-specified. OSRAM DALI ECGs (1) can communicate DALI and, hence, be individually dimmed by applying a DC voltage supply.

The "System Failure Level" has priority over the Power On Level, i.e.

The "System Failure Level" can be configured individually for each

The OSRAM DALI LUMINAIRE TOOL (OSRAM DLT) is a testing and programming tool for luminaries with DALI controllers. All functions (except for the individual OSRAM serial number Chip Identification Number (CIN)) correspond to the DALI standard and are hence vendor-independent.

The functions of the OSRAM DLT are:

• Luminaire function test (for production)

• Reading of all DALI parameters (e.g. in the event of complaints)

3.5 Basic switching actions of 1…10 V control gear

The simplest type of light control can be realized via an appropriate

logarithmically-dimensioned potentiometer (available from the electrical trade). Because the control power of the OSRAM DIM ECG is generated by the ECG itself, the resistance value is dependent on the number n of the connected ECG. It can be calculated according to the formula:

If the calculated value is not contained in the resistance table, a similar

value should be selected as otherwise full modulation of the lamps is not possible (this overdimensioning may possibly lead to the fact that the whole rotation angle of the potentiometer for the brightness control cannot be used). The potentiometer must be designed for at least a power of P

Potentiometer

= 2.8 mW · n.

A mains switch is also required for switching the lighting system. When

connecting the potentiometer, it is important to note that the full lighting level is reached by turning to the right. When connecting more than 2 OSRAM DIM ECGs, it is recommended to use a DIM MCU manual control. Detailed information on this can be found in the relevant documentation (LMS portfolio, see www.osram.com/ecg-lms).

3.5.1 1…10 V: Staircase operating modes

As a basic principle, frequent switching is not ideal for fluores-

cent lamps and compact fluorescent lamps. Hence, bulbs are still used in applications with extremely high switching frequency despite the high energy consumption. In staircase operation, OSRAM DIM ECGs dim the light (1 % luminous flux) when it is not required. This avoids unnecessary switching operations and saves energy. Further benefits of the staircase circuit: Because the light is not completely switched off, a certain amount of light still remains available as an orientation light. When needed, the full light is im- mediately present, without having to wait for a preheating period. Typical applications of the standby circuit are all applications with high operating cycles, such as staircase, hallway or underground car- park, especially when the light is controlled with motion detectors or timer switch.

3.5.1.1 Applications a) Stairwell lighting timer switch

Here a special stairwell lighting timer switch (e.g. Siemens: Type 5TT1

303, see Siemens Catalog) provides the readiness switching of the OSRAM DIM ECG. Functionality: The stairlight timer switch switches on the OSRAM DIM ECG at the push of a button (100 % light). After max. 10 min (time can be adjusted) the light is lowered to a preselected level without intermediate stages. After a total of 30 min it is switched off entirely. This 30-min cycle can be restarted at any time by pressing a switch. Thus, the lamp-protecting mode is employed in the evening hours when the staircase is used more frequently. The light only switches between the dimmer settings, real switchings are infrequent. At night, when the stairwell lighting is not required for prolonged periods, the remaining 13 % energy consumption are also still stored at the lowest dimmer setting.

Figure 25: Stairwell lighting timer switch

b) Stairwell lighting timer switch and motion detector

Because the button engages the line voltage (L), it can be replaced by

a motion detector. Parallel switching with the switch is also possible. Because the switch-on time is set on the stairwell lighting time switch, the switch-on time of the motion detector can be set to a minimum.

Figure 26: Stairwell lighting timer switch and motion detector

3.5.1.2 Control via analog output The external control with an analog output 0…10 V (e.g. PC card)

is basically possible. This control module must be capable of taking the current supplied by the ECG in the control line and of reducing the control voltage to at least 1 V. For that reason, however, the analog output must fulfill two requirements: It must be potential-free and may not therefore be connected galvanically with touchable parts or circuits that are subject to SELV requirements (test voltage 2500 V, the test voltage to grounded parts is 1500 V). The analog output can operate as a current sink because it must take the control current of the OSRAM DIM ECG. Mostly, it is not known whether and how much current an analog output can take but assistance can always be provided by an interface circuit.

3.5.1.3 Interface circuit

In the case of up to three OSRAM DIM ECGs, it is recommended to

connect the control inputs of the ECG directly with the analog output (e.g. PC card) and, in the case of four and more OSRAM DIM ECGs, to interconnect a signal amplifier. Then start up the system, set the control voltage to 0 V and check with a multimeter directly at the analog output. If the measured value is less than 1 V, the situation is okay and the system can be started. If the control voltage here is greater than 1 V, the analog output cannot take enough current and an additional current sink is required in the form of a parallel switched resistor R. The required value is determined as follows: At a default control voltage of 0 V, a potentiometer (approx. 5 kΩ linear) is also set on the analog output and a 1 V control voltage set with it. Disconnect the potentiometer and measure the resistance value (must be greater than 680 Ω), provide and connect corresponding fixed resistor (construction form 0207, power rating 0.25 W, possibly next smaller resistance value).

3.5.1.4 Control via instabus EIB

Dimmable ECG with 1…10 V interface can be easily integrated in

installations with the instabus EIB building control system. The link between EIB and the dimmable lighting system is a switching/dimming actuator. A switching/dimming actuator is required for each lighting group. The digital bus signal is converted by the switching/dimming actuator into the analog 1…10 V control voltage for OSRAM DIM ECGs. The ECG is switched on/off by an integrated relay contact. Different functions can be parameterized: on, off, brighter, darker, as well as a default defined control voltage. Sensors for daylight control etc. are normally connected at the instabus level. Detailed information is available from manufacturers of the instabus EIB.

3.6 Special wiring diagrams, tips and tricks

3.6.1 Temperature-dependent control

The recognized temperature problems in dimmed fluorescent lamps

can be resolved by a temperature-dependent lower limit of the dimmer setting.

The latest generation of the QTi DIM (as of the end of 2008) does this

automatically. For older versions, the following implementation applies:

The stability threshold (stable dimming operation at low temperatures

(< 10 °C)) depends greatly on the lamp tolerances. In control types where the lamp starts at 100 % (e.g. stairwell switching), the temperature limit can be lower. Therefore, in an automatic control both the response temperature and the control voltage should be adjustable. The following circuit is recommended:

–

Temperature controller

Main control unit

–

Aux. control unit approx. 4V, e.g. DIM MCU

–

Figure 28: Temperature-dependent control

The temperature controller can be a room temperature controller for

heating control, for example. The switching temperature (e.g. 0 °C) should be as precisely adjustable as possible. The switch must be a closer, i.e. must be closed at high temperatures. Such appliances are offered with a bimetal contact (e.g. 2NR9 090-1, power supply not required) or with a temperature sensor (e.g. 2NR9 078, power supply required). Any existing heating resistors for thermal feedback (RF) or nighttime temperature reduction (NA) are not connected. The only power supply line is the possibly required power supply. Depending on the application, different protection types are necessary. Further details are available from specialist personnel for heating and air handling units.

3.6.2 Limitation of the control voltage

For certain applications, it is necessary to set an upper or lower limit

of the control voltage for the OSRAM DIM ECGs. Reasons for this can include special lamp-ECG combinations and occurrence of flickering at lower temperatures, for example.

a) Upper limit

The simplest option of dealing with this is the parallel switching of a

Zener diode with the corresponding value. For a limit of 7 V, for example, a Zener diode with the nominal value of 7 V or a value close to this must be used. (Zener diodes are available as the E24 series. The type Bzx 55C xVx is recommended. For example, for xVx a value of 7V5 = 7.5 V must be taken. At least 20 ECGs can be controlled with this type.) As a general rule, for parallel switching of several control units the control unit with the lowest value applies as the default for the OSRAM DIM ECG. This applies for all passive control units, i.e. units that acts as a current sink.

b) Lower limit

An effective lower limit can be realized by a series connection of 2

control units. The sum of the two units is effective. With one unit, the default control voltage of the other unit cannot be undercut. Attention: In a series connection, two control units (e.g. DIM MCU) is the smallest achievable control voltage approx. 2 V (~= 4 % luminous flux) connections must be realized according to the diagram.

Figure 30: Lower limit of the control voltage

3.6.3 Line length of the 1…10 V control line

The control line length is only limited by the drop in voltage. It can

generally be said that a line length of 100 m is completely noncritical. For a more precise estimate, the following formula can be used:

For example, with 1.5 mm², strip of luminaires, supply at the begin-

ning:

= 35 km/no. of ECGs

max

= 350 m for 100 ECGs = 700 m for 50 ECGs

Systems of any size can be realized with DIM SA signal amplifiers.

3.6.4 1…10 V DIM ECG and emergency lighting

QUICKTRONIC DIM is suitable for emergency lighting systems in ac-

cordance with VDE 0108. If QUICKTRONIC

DIM are used in emergency lighting systems, the control line should be disconnected by suitable measures at the plus pole during emergency operation. Corresponding, simple-to-wire changeover converters that pass on a presettable control voltage to the OSRAM DIM ECG, thereby enabling battery-saving emergency lighting operation at less than 100 % luminous flux, are commercially available.

Figure 31: Emergency lighting with 1…10 V DIM ECG

It must be noted that some accessory components (e.g. DIM SA sig-

nal amplifiers) are not approved for battery operation. Therefore, it is important to make sure that these components are never connected to DC voltage. In this case the signal amplifier, for example, constitutes a fixed resistance that is connected to the control line. The dimmer setting of an ECG is then around 20 %, and accordingly higher for more than one.

3.7 Terminals/Cable cross-sections/Wire stripping lengths

For the combined terminals used in the QTi DALI/DIM for T5 and T8

fluorescent lamps, both solid lines as well as flexible lines are permissible. The contacts of the terminal can be made at the top via a socalled insulation displacement contact and via a plug contact (wire stripping length 8.5-11 mm). Likewise for ECGs with push terminals (HF DIM, QTi T/E DALI/DIM), both solid lines (wire stripping length

8.5-9.5 mm) and flexible lines are also permitted provided these are tinned, ultrasound welded or fitted with wire-end sleeves.

ment contacts

3.7.3 Basic insulation

IEC 61347 demands basic insulation between the control circuit and

mains supply for control inputs. The DALI standard (IEC 62386) is related to this. Consequently, the DALI line is “only” basically insulated and must be treated like the mains voltage for this reason as is the 1…10 V interface.

3.7.4 Lamp holders

The lamps must be mechanically secure and make contact in the

lamp sockets. The holders must be selected according to the type of ECG/lamp used.

3.7.5 Master/slave circuit

(2-lamp ECG for the operation of 2 single luminaires) Master/slave

operation with multilamp dimmers is not permitted. This is because of the capacitive leakage currents that can lead to imbalances, different luminances and unstable operation in the dimmed state (flickering).

3.7.6 Minimum reflector gaps

The reflector must never rest on the lamp, otherwise this can lead to

vibrations and noise emissions. A minimum gap of 6 mm must be maintained between the lamp and the reflector in all luminaires. If the gap is less, this can lead to different brightnesses along the length of the lamp due to the capacitive leakage currents. Flickering can also occur.

tures:

For HE lamps, this point is reached at the same power density. Because of the 100 % power being approx. only half as high, the dimmer setting is 60 % here. The HO49 lies between HE 14…35 W and HO 24…80 W/Dimming of the amalgam lamps T5 HO CONSTANT (24 W, 39 W, 54 W, 80 W), CFL (DL CONSTANT 40 W, 55 W, 80 W and T/E IN PLUS 26 W, 32 W, 42 W, 57 W) is possible.

The temperature range of the luminaires can be expanded down-

wards by raising the lowest dimmer setting until the light has reached a higher inner temperature, otherwise flickering or/and starting problems of the lamp can be expected. From the end of 2008 units do this automatically.

3.8.1 Intelligent thermal management in hot luminaires Intelligent thermal management enables operation in a wide ambient

temperature range through power reduction.

From the generation at the end of 2008, the QTi (DALI)…DIM ECG

from OSRAM include the feature of intelligent temperature regulation.

Features

• Notable increase in the light yield (lm/W) of hot luminaires

• Virtually no loss of luminous flux (lm) compared with uncontrolled

operation

• No reduction in the service life of the ECG within the control range

• Simplifies the safety approval of hot luminaires

• Relieves luminaire components

Note:

• Limits the t

temperature to < 80 °C (depending on installation con-

dition), but never switches the ECG due to excessive temperature

• Thermally problematic luminaires do not necessarily become stan-

dard conformant devices, even with these ECGs

• Power reduction is carried out up to 50 % of full load operation

Functionality

The ECG measures the ECG temperature once per minute. At the

selected limiting temperature it begins to reduce the power in order to lower the temperature of the luminaire and to prevent the temperature of the ECG from increasing further. The T

temperature lies between

75 °C and 80 °C depending on installation conditions (e.g. heat coupling into the ECG from top or bottom).

A reduction of the system power by 10 %-20 % at an ambient tem-

perature of 25 °C is sufficient in most cases even in hot luminaires, however, only approx. 1 %-2 % light is lost because the level of efficiency of the system increases.

Dimming is always possible the temperature regulation may affect

the upper dimming level only significantly.

The regulation of the lamp power compensates the loss of light

output in hot luminaires.

Measurements using an example of a narrow 2x80 W luminaire: The precise scaling depends on the type of luminaire and the installa-

tion conditions of the ECG.

Why are the light losses so small due to the temperature limitation?

Assuming a luminaire whose inside temperature (= lamp ambient

temperature) is to be lowered from 65 °C to 55 °C. A reduction of the system power by 20 % is required for this. The diagram shows the Φ(T) curves of T5 lamps for 100 % and 80 % system power.

During the transition from the 100 % curve to the 80 % curve and the

lowering of the lamp ambient temperature by 10 °C, the luminous flux remains roughly the same.

QTi (DALI)…DIM never stop thinking: Instructions for the ther-

mal coupling of lamp and ECG

Temperature limitation is control engineering in the classical sense

and requires, therefore, a closed control loop: The lamps must be able to heat the ECG. This is ensured when the ECG and lamps are

housed in the same luminaire space, separated by a reflector if necessary.

If the ECG is mounted outside the luminaire, it cannot exploit the ben-

efits of the thermal managment.

3.8.2 Color temperature

Between the maximum and minimum luminous flux of the lamp the

color temperature of the lamp changes – in a DULUX L this is approx. 150 Kelvin. Due to the great difference in luminance density, the color difference appears to be visually considerably greater. As a result, the subjective perception of the human eye does not reflect the objective color temperature change. Directly after changeover from maximum to minimum luminous flux, a temporary color displacement of up to 400 Kelvin occurs (displacement to the red end that decreases after approx. 30-40 minutes to the color difference mentioned above (stabilization phase)).

Figure 40: Color-phase diagram acc. to DIN 5033

Note:

Measurement of the most similar color temperature with greatly

dimmed lamps places the highest demands on the electronics and receiver of the color measuring device. Incorrect valuations cannot be excluded with conventional color measuring devices.

3.8.3 Outdoor applications

For applications out of doors a special OSRAM housing, the

“OUTKIT”, is available for protecting the ECG against humidity. It is available for ECGs with a headroom of 30 mm or even 21 mm, in the lengths of 360 mm and 423 mm. Details of this can be found in the current light program. For outdoor applications the temperature range of the system lamp-ECG should be examined in detail. In all outdoor applications attention must be paid to sufficient mains quality (above all, lightning protection) so that the ECGs are not damaged.

3.8.4 Functional test of luminaires The dimmable QTi family from OSRAM (DALI and 1…10 V) gives in

the luminaire test (with 10 Ω filaments) the following power per lamp:

1-lamp/2-lamp (T5 and T8): 32 Watts 3-lamp/4-lamp (T5 and T8): 16 Watts

This function is independent of the deployment of the actual lamp.

For special applications/luminaires, the filament detection can be switched off – details on request.

If the end test of the luminaire is carried out in TouchDIM mode,

note that the lamp must be dimmed to 100 % light before the disconnection of the luminaire from the mains supply . Only in this way is it ensured that the light can also be switched on with the protection (without control unit) (DALI standard) during installation of the luminaire. If the luminaire was switched off via TouchDIM the luminaire also remains off after a loss of voltage – the installer could mistakenly assume a defective ECG in this case.

If the luminaire has mains voltage applied to it for the first time (without

control unit), it must be switched on with 100 % luminous flux (= DALI factory setting). The changeover of DALI to TouchDIM mode or vice versa, assumes a mains voltage failure of the ECG (safety interlock).

Figure 41: ECG lamp combinations (amalgam lamps)

Functionality of QTi DALI/DIM: Power boost and amalgam

lamps

The amalgam releases just as much mercury as is required for the

discharge and, as a result, considerably decreases the luminous flux at high or low temperatures. After a change of the operational mode, however, it takes a number of minutes until the mercury balance is discontinued again. If the lamp is switched off for a prolonged period – no discharge and no mercury requirement – the amalgam collects all the mercury. On a restart, therefore, there is initially a lack of mercury which can be detected by the "pink phase“.

If the lamp is dimmed at the same time, its maintaining voltage can

rise to non permitted values and the discharge can become instable. Here the power boost of the QTi DALI/DIM comes into play: It

automatically increases the lamp power in order to lower the lamp voltage and to stabilize the discharge phase. Then when the amalgam has released enough mercury, the lamp power is automatically reduced again and the lamp can be dimmed normally.

Also in normal mercury lamps the power boost takes effect and

simplifies dimming during the ignition phase of the lamps as well as for

very low temperatures:

When there are instabilities in the lower dimming level, the Power

Boost regulation helps to stabilize the burning conditions.

Functionality of QTi DALI/DIM: Relative luminous flux > 90 %

over an additional expanded temperature range from 0 °C to +70 °C

Mercury T5 lamps reach their luminous flux optimum at an ambient

temperature of 35 °C – but only if their mercury household is not influenced by additional electrode heating. The QTi DALI/DIM units, therefore, have a cut-off, i.e. the electrode heating is switched off when it is not needed.

It can be shown that, at low ambient temperatures, amalgam lamps

give off more light when the electrodes are heated somewhat.

Neu!New!

At high temperatures, however, this effect is reversed. The QTi DALI/ DIM uses its internal temperature sensor in order to switch off the electrode heating at a sufficiently high temperature.

This means a further increase of the luminous flux of cold amalgam

lamps is achieved: The temperature at which the luminous flux falls below the 90 % line drops from +5 °C to 0 °C.

3.9.1

Dynamic dimming procedures with amalgam lamps

The frequency of dimmer setting changes is primarily limited by the inertia of the control input, a passage of the dimming range takes approx. 200 ms for 1…10 V, and approx. 50 ms for DALI. Thus, rapid flashing blurs to a middle dimmer setting. At 10 Hz, this effect is already particularly visible at 1…10 V. No damage to the lamp is to be expected. A dimming process every 2 s is possible without any problem.

3.9.2 Benefits of amalgam technology

Dimming of amalgam lamps is also suitable for outdoor applications.

Note:

Sufficient attention should be paid that the ECG is protected against external influences (IP67).

Figure 44: Relative luminous flux against ambient temperature in the

luminaire of T5 standard and T5 HO CONSTANT lamps

Figure 45: More light from new luminaires thanks to amalgam tech-

nology

Note:

•

• Amalgam and mercury lamps must never be mixed in multilamp

ECGs because the power increase available in amalgam lamps would lead to a vigorous overshooting of the light in a mercury lamp. In addition, the synchronization in the lower dimming range would be poor.

• No release: Dimming of a T5 amalgam lamp with predecessor units up to the end of 2008 (DALI and 1…10 V):

- Voltage peaks arise through unwanted controller oscillations

• For dimmer settings below 30 %, the following applies:

- Unfavorable operating condition leads to lamp flickering and a

reduction of the lamp service life

• Recommendation: Dimming of amalgam lamps is possible,

but this is not released by OSRAM. Burning-in of the lamps at 100 % luminous flux after each restart for approx. 2-3 minutes, then dimming. In principle, however, dimming of T5 amalgam lamps with predecessor units is not recommended for the reasons mentioned above.

Oscillations – typically in the lower third of the dimming range – can develop

when fluorescent bulbs with electronic control gear are dimmed, which are caused by the interaction of lamp characteristic, lamp time constants, resonant circuit and control.

4 System energy consumption

and dimmer setting

Because there is a largely linear relationship between the power

consumption of the DALI/DIM systems (lamp and ECG) and the dimmer setting, the power consumption PN(d) can be calculated for each dimmer setting d (in percent) from the values PN100 % (100 % nominal power, PN = Power Nominal) and PN1 % (nominal power of 1 %) (depending on ECG lamp combination, available on request):

• Automatic safety shutdown on lamp defect and at the end of the

lamp life (EoL T2)

• Optional cable clamps for snapping into the housing

Figure 49: Principle Optional cable clamps for snapping into the

Numerous applications in the downlight sector can be covered by

one luminaire type in combination with the new QTi T/E DALI/DIM

generation from OSRAM. Thus, for example, it is possible to design

the lighting of a building with different room heights and different

luminaire installation locations (e.g. corridors, foyers etc.) so they are

simple and flexible to dim. Thus, several “lumen packages" are pos-

sible for each room. Due to optimized filament preheating, the lamp

starts inside 0.6 seconds which means the user does not have to

accept unnecessary waiting periods after switching on.

The intelligent QTi T/E DALI/DIM units automatically adjust the fila-

ment preheating for very low temperatures. Thus, amalgam lamps

can be operated in a stable way.

Intelligent power reduction at excessive temperatures ensures a

high service life and reliable operation.

6 The Activity Group DALI

(AG DALI)

The “DALI" workgroup was set up in 1999 under the auspices of the

ZVEI (the German Central Association of Electrical Engineering and

the Electrical Industry) with the aim of establishing this new standard

on the market. All the leading manufacturers of ECGs and controllers

are represented in this Activity group so they can develop and market

their products in accordance with the requirements of the DALI stan-

dard. The AG DALI is an open community that any company can join

for a modest annual fee.

The AG DALI has published a “DALI Handbook” and various other in-

formation brochures that can be downloaded from their home page. See: www.dali-ag.org

8 Frequently asked questions (FAQ)

8.1 DALI part

8.1.1 TouchDIM

• Can the TouchDIM function and a DALI controller be used at the same time?

No. Either a DALI controller or the TouchDIM function! TouchDIM

and DALI operation are mutually exclusive.

• How do the ECGs behave after a mains voltage failure?

The DALI ECG of the QTi series automatically reestablish the previ-

ous status. Both the switching status (on/off) and the dimmer setting are taken into account here.

• Can devices that do not run synchronously be synchronized again?

Yes. The procedure is as follows:

Press switch for long period (> 3 s) (all ECGs on). Press switch for short period (all ECGs are switched off). Press switch for long period (all ECGs switch on with minimum dimmer setting and then fade up) ! Long – short – long

• Is it also possible to connect more than one DALI ECGs to a switch?

Up to 6 ECGs can be controlled by one switch, the number of con-

trol sections is limited to 2. With one DALI repeater, up to 64 DALI ECGs can be operated in TouchDIM mode.

• How long should the cable be between the switch and the ECG?

The line length should not exceed 25 meters. In the case of longer

lines, additional measures must be taken in order to suppress interference (e.g. bell transformer).

• Which switches can be used?

All button can be used that are suitable for mains voltage, but no

button with glow lamps.

• Does TouchDIM only work with 230 V AC voltage?

No, TouchDIM control is possible with AC voltages between 10 V

and 230 V (effective value!).

• Can I also use DC voltage for TouchDIM?

No, it must be AC voltage with a frequency between 46 and

66 Hz.

• Can a TouchDIM system be upgraded with a DALI control- ler?

Yes, an upgrade is possible at any time. Changeover of the DALI

ECGs from TouchDIM to DALI takes place automatically after a power outage on the ECG when the first DALI command is sent.

TouchDIM and DALI control cannot be used at the same time!

• Can the motion function of the TouchDIM sensor be switched off (holiday mode)?

Yes, the so-called "holiday mode" prevents the lighting system be-

ing switched on by the motion sensor. It is activated by doubleclicking on the switch if the light has not been manually dimmed in the previous 30 seconds. The motion function is active again if the luminaire is switched on manually at the switch.

8.1.2 DALI in general

• Do the ECGs have to be addressed in DALI?

No, it can also function without addressing (broadcast mode).

• What is the difference between DSI and DALI?

DSI is a corporate solution, not a general standard like DALI. DSI

does not allow digital addressing so it is not possible to form groups freely or check individual lamps for faults! Groups have to be formed by wiring as well as in the case of 1…10 V systems.

• Does attention have to be paid to the group arrangement in DALI when wiring the system?

No, the groups are generally assigned (addressed) when the sys-

tem is started up.

• Does attention have to be paid to the polarity of the DALI control line?

When OSRAM DALI control gear is used there is no need to worry

about polarity.

• How can DALI ECGs be addressed?

They can be addressed individually, in groups or all together.

• Can I get feedback messages from DALI ECGs?

Yes, all device settings as well as the device status, such as lamp

faults, can be checked.

• Can a DALI ECG belong to more than one group at the same time?

Yes. Each DALI controller can belong to up to 16 groups.

• Where are the data for the group assignments and light scene values stored?

They are stored directly in the internal EEPROM of the ECG.

• Are the data in the ECG lost if there is a power failure?

No, the data are permanently stored in the ECG. They are retained

even if the power failure is prolonged.

• What happens if an ECG fails?

The ECG simply has to be replaced and adjusted to the appropri-

ate settings (the procedure depends on the control unit).

• What happens if a control unit is faulty?

If the DALI interface voltage is lost, all ECGs take on the so-called

"system failure level" (ECG factory setting: 100 % light).

• Can DALI be integrated in superordinate building management systems (e.g. EIB or LON)?

Yes, by using gateways or control units with the appropriate inter-

face.

• Is DALI a competitor to EIB or LON?

No, DALI is only a subsystem of the building management system

for controling the lighting.

• Can 1…10 V components also be incorporated in a DALI lighting control system?

Yes, by using DALI to 1…10 V converters.

• Can existing 1…10 V lighting systems be upgraded with a DALI controller?

Yes, a DALI to 1…10 V converter is needed

naire group (e.g. DALI CON 1…10 SO).

• Can the wiring of the DALI ECG be checked on a building site?

This depends on the control unit used. DALI ECGs that are still in

their factory setting always produce 100 % light when the mains voltage (with protection) is applied.

for each 1…10 V lumi-

• What insulation is required for the DALI control line?

The DALI control line must be approved for mains voltage (as in the

case of the 1…10 V interface).

• Can existing 1…10 V control lines be used?

Yes, provided they are rated for mains voltage.

• How long can a control line be?

A maximum of 300 m between the controller and the furthest con-

nected DALI unit.

• Can control and power cables be laid together?

Yes, a 5 x 1.5 mm

NYM cable can be used, for example.

• What line cross section must the control line have?

Up to 100 m: min. 0.5 mm2/from 100 m to 150 m: 1.0 mm2/from

150 m: 1.5 mm

• Can any company develop a DALI controller or DALI ECG?

Yes, there are no restrictions except that the DALI logo

may only be used by members of the DALI Activity Group. See also http://www.dali-ag.org/.

• What happens if I use DALI ECGs from different manufacturers in the same system?

The controllers are DALI-compatible if they carry the DALI logo. It is

important to note, however, as in 1…10 V technology, ECGs from different manufacturers can result in different filament preheating times and different lamp starting times.

• Can controllers from different manufacturers be combined?

No, DALI ECGs are interchangeable, but the control components

cannot normally be combined.

• Is it possible to limit the maximum and minimum luminous flux?

Yes, these values can be changed/limited with the appropriate

controller in the ECG.

8.1.3 DALI to 1…10 V converter

• Is it possible to switch and dim

with DALI to 1…10 V converters?

Yes, with the converter both are possible.

• Can the converter also offer the TouchDim function?

Yes, the converter behaves like a DALI ECG here in TouchDIM-

mode 1.

• Why does the converter have characteristic changeover?

8.1.4 Troubleshooting TouchDIM mode

Before you start troubleshooting, please check each time that the

So that it is possible to compensate for the different behaviours of incandescent lamps and fluorescent lamps. You should therefore choose between the linear characteristic (incandescent lamps) and the logarithmic characteristic (fluorescent lamps) depending on whether the converter is operating a fluorescent lamp ECG or a dimmer for incandescent lamps).

controller is wired according to the operating manual and that the corresponding power supply is on. In the case of luminaires, please also check the light sources and replace if necessary.

• The ECG are not reacting as expected to switch operations.

If the button was pressed too long (> 1 second), the lamp starts

at the lowest dimmer setting which may be difficult to see in bright ambient surroundings.

• Individual luminaires have a different brightness level and conflict with one another.

→ Manual synchronization of the system: Long button (>3 s) press (all lamps on). Short button press (all lamps are switched off). Long button press (all lamps switch on at minimum dimmer setting

and dim upwards).

• The ECGs react without any button being pressed.

1. The line between button and luminaire (ECG) is possibly too

long.

2. A button with glow lamp was used which is not permissible.

• The motion detection function of the TouchDIM sensor is not working.

1. The luminaire was switched off by double-clicking the switch

and this has deactivated the motion detection function (holiday mode)

2. The available daylight is sufficiently bright. Cover the sensor and

observe the response of the luminaire.

3. The motion detection is deactivated for 30 s after the lighting

system has been switched off manually. This time will only expire if there are no more people in the detection zone.

• The luminaire is not regulating its the brightness to the setpoint value

1. After setting the brightness, you must press the button twice

inside 30 s (to store the setpoint value). If you press the button later than that, the holiday mode will be activated.

2. The dimming was carried out manually – this deactivates the

brightness control. Switch the luminaire off and on again.

3. No setpoint value has been stored.

Set the required light value and double-click to store it.

• Holiday mode cannot be activated.

The brightness level has been changed within the past 30 seconds

– holiday mode can only be activated after this time.

8.1.5 Troubleshooting DALI controllers

• The ECGs are not reacting to commands from the controller?

Please check the wiring where approx. 16 V

should be applied to

the DALI terminals of the ECG.

8.1.6 DALI to 1…10 V converter

• Not all lighting strips can be switched off.

Please check that the power supply of the relevant lighting group

has been routed via the load contact of the respective converter.

8.2 1…10 V DIM ECG part

• How long can the 1…10 V control line be?

The maximum permissible length of the control line is 100 m (also

applies to the DALI control line). (Note: Due to the low control current, a drop in voltage is only noticeable on the control line after approx. 300-400 m)

• What line cross section should the 1…10 V control line have?

1.5 mm² is recommended as the cross section. The insulation of the line used must be designed for mains voltage.

• Can control and supply lines be laid together?

•

Yes, control and supply lines can be laid together (VDE 0100 520

Section 528.11). The following points must be noted:

• The lines used must comply with the maximum operating volt-

age that occurs. (VDE 0100/11.85, T520 Section 528.11)

• When laying core lines in installation ducts or channels, only the

conductor of a main current circuit, including the associated auxiliary circuits, may be laid.

• Also a number of main current circuits, including the associated

auxiliary circuits, can be laid in one line. (VDE 0100/11.85, T520 Section 528.11)

•

How can permanently selected lighting levels be controlled simply and economically?

A simple control for preset lighting levels with 100 % or 1 % lumi-

nous flux and several values lying between is possible with fixed resistors or Zener diodes.

• Can 1…10 V dimmable ECGs from OSRAM be used for emergency lighting?

Yes, but the use of dimmable ECGs in systems for emergency light-

ing is associated with additional expense. Components such as signal amplifiers, ICM 10 or the light constant holding module would be destroyed by supplying them with DC voltage. This means that, in the case of switching over to a DC voltage supply, these components must be disconnected from the mains supply.

• Can compact fluorescent lamps with a 2-pin base be dimmed?

No, ECG operation of 2-pin lamps is not generally allowed. The

glow igniter integrated in the base can lead to problems such as poor, unreliable ignition, reduced lamp service life or destruction of the ECG. Here additional heating of the lamp electrodes is not possible in dimmed operation which would lead to a significantly reduced lamp service life. Basically, only 4-pin base lamps with the designation /E (e.g. DULUX S/E, D/E, T/E) can be operated on the ECG and dimmed with this.

• Does continuous operation in the lowest dimmer setting have an effect on the service life of fluorescent lamps?

Long-term operation of fluorescent lamps and ECG from

OSRAM in the dimmed state has no negative influence on the service life of the lamp.

8.2.1 Troubleshooting 1…10 V

•

• Lamp does not burn with 100 % luminous flux

The control line is not connected or not correctly connected to the

control unit, or the control unit is not a sufficiently good current sink and, hence, cannot reduce the control voltage.

Check the wiring. Check that the control voltage is reduced while

dimming and, if necessary, install a parallel resistor in the control line.

Also one or more control inputs may be pole reversed:

• Disconnect control unit

• Subdivide control circuit

• Further subdivide control circuit

• Lamp always burn at minimum brightness

+ and - connectors of the control line are reversed, or short circuit

in the control line.

Connect lines with correct polarity, check wiring

• The lamp does not show the required luminous flux when controlled with potentiometers or fixed resistors.

Potentiometers or resistors are wrongly dimensioned. Check the

values

• Insufficient brightness along the lamp

Spacing of the reflector to the lamp is too small, capacitive dis-

charge currents occur.

Increase gap between the reflector and the lamp

• Synchronous lamp flickering

Fault is outside the dimming system, e.g. N conductor disconnec-

tion, control voltage not OK

Check N conductor connection and control unit

9.1 Starting currents and max. number of ECGs in automatic cutouts

Figure 51: Starting currents and max. number of ECGs in automatic

cutouts (B characteristic), measurement at U

= 230 V

9.1.1 Minimum B/C characteristic triggering levels

The minimum triggering levels increase from B to C characteristic by

the factor = 1.67, i.e. not quite a factor of 2. At the same time, however, the total current must not exceed the value of the automatic cutouts.

9.2 DALI fade time and fade rate The fade time can be set to any of 16 different steps (0 to 15) and

denotes the fade time to go from one scene to another (room lighting states). The fade rate, which can also be set to any of 16 settings, is the number of fade steps per second and acts on the speed with which the lighting is faded up or down manually.
