OPTOTRONIC® LED drivers for outdoor applications meet these requirements and unlock the full potential of LEDbased light sources. Thanks to the high flexibility of the programmable OPTOTRONIC® 4DIMLT2 LED drivers, LED luminaire systems can be optimally adapted to the required conditions and their cost can be optimized. With the four integrated dimming functions (4DIM), significant energy savings and a reduction of greenhouse gas emissions can be achieved. The standardized DALI interface allows for the simple integration into telemanagement systems (for example with the OSRAM Street Light Control system) and also a harmonized control of the output light level in contrast to a 0–10 V interface. Moreover, these LED drivers already fulfill the new stand-by requirements that will become effective in Europe in 2016. Due to the large operating window (voltage/current) of these LED drivers, both OSRAM LED modules for outdoor applications and customer-specific LED modules can be operated. This also means that the overall amount of different LED drivers on stock can be kept low and that the overall complexity of luminaire maintenance over the entire life cycle can be reduced. With the LEDset2 interface, OSRAM has created a new path towards standardizing the communication between the LED driver and the LED modules. Without reprogramming, LEDset2 ensures optimal efficiency, a high level of reliability and the adaptability of the LED drivers to the latest LED technologies. Finally, due to integrated overvoltage protection, LED drivers with 4DIM functionality also set a new standard against common mode surges of up to 10 kV (single pulse) for class I and II luminaires. 3 4DIMLT2 LED drivers | Introduction 1.2 4DIMLT2 product family The 4DIMLT2 product family consists of four different output power classes of up to 165 W. All four types have the same 4DIM dimming capabilities and the new multi-vendor LEDset2 interface. They can be programmed via the Tuner4TRONIC® software. The following overview shows the main features of these new LED drivers. Note: The technical data of the OT 165/170-240/1A0 4DIMLT2 E are preliminary. For design-in, please consult your OSRAM sales contact.

Bidirectional communication and the query of status information from the LED driver are also possible via DALI. StepDIM/StepDIM inverse The new generation LEDset2 is an improved LED module interface for the combination of single or multiple LED modules with one LED driver via a single analog control line. This interface enables external current setting and temperature monitoring. The LEDset2 interface has no auxiliary supply and is not compatible with LEDset (Generation 1). LEDset2 has an absolute current coding, while LEDset (Generation 1) only has a relative one. StepDIM External temperature sensor Dimming via an external control phase: Predefined dimming levels can be varied via the Tuner4TRONIC® software and the polarity of the phase. The SD/SD2 port also allows control via a mains-powered presence sensor. AstroDIM/presence detection AstroDIM PRESENCE Automatic dimming via an integrated timer (no real-time clock): Five independent dimming levels and zones can be set with the Tuner4TRONIC® software. Brightness variation is possible in combination with an external presence sensor. MainsDIM MainsDIM Ext. NTC This feature allows the temperature protection of the LED module or the complete luminaire in hot ambient temperatures via an external sensor (e.g. NTC, negative temperature coefficient resistor). The derating can be modified via the Tuner4TRONIC® software. Integrated overvoltage protection 6 kV EQUI (DIF) 6 kV (COM) The 4DIMLT2 drivers have an integrated overvoltage protection of up to 6 kV for differential and 8 kV for common mode overvoltages. They are also capable to withstand one single 10 kV common mode pulse. The protection levels are also applicable for the StepDIM port. Dimming via mains voltage amplitude: This feature is often used in combination with magnetic ballasts in outdoor applications. The dimming behavior can be set via the Tuner4TRONIC® software. CLO (constant lumen output) CLO The decrease in the luminous flux of an LED module can be compensated over its entire lifetime via a preprogrammed current curve. This not only ensures stable lighting but also saves energy and increases the lifetime of the LEDs. Fit for SMART GRID SMART GRID With this feature, the power consumption and operating hours (resettable) of the LED module can be monitored. Additional advantage: “Fit for SMART GRID” can also provide better analysis of the lighting, thus ensuring safe operation of the system. 5 4DIMLT2 LED drivers | Introduction 1.3 Nomenclature The product name of each OPTOTRONIC® 4DIMLT2 LED driver is defined as shown below.

Please consider that the certificates are only valid within the nominal output current range. 6 4DIMLT2 LED drivers | Introduction 1.4.1 Supported LEDs Table 4 shows how many LEDs can be driven with one LED driver. The values are based on the following assumptions: Vf LED = 3.1 V at 1050 mA and Vf LED = 2.5 V at 70 mA Table 4: Supported number of LEDs Type Minimum number of LEDs Maximum number of LEDs OT 40/120-277/1A0 4DIMLT2 E 8 18 OT 60/170-240/1A0 4DIMLT2 E 12 37 OT 90/170-240/1A0 4DIMLT2 E 23 60 OT 165/170-240/1A0 4DIMLT2 E 36 90 Warning: The real number of supported LEDs needs to be checked according to the minimum and maximum forward voltage in the worst case conditions. They have to match the minimum and maximum output voltage of the used LED drivers. The forward voltage of the connected LED module in dimming condition is lower than the forward voltage in nominal condition but still has to be above the minimum output voltage of the LED driver. 1.4.2 Current foldback The intelligent 4DIMLT2 family allows a safe start-up of the system, even if the power consumption or the total forward voltage of the LED module exceeds the maximum output power or voltage of the LED driver. In this case, the unit reduces the current until the maximum output voltage [1] or power [2] is not exceeded anymore. If no stable operating point is achieved, the unit switches on and off continuously or switches off completely.

The 4DIMLT2 family offers two modes for current setting, which can be set via the Tuner4TRONIC® software: — Fixed current: Current setting via programmable interface — LEDset2: Current setting via the LEDset2 interface Figure 4: Setting of the operating current 2.1.2 LEDset2 mode The LEDset2 interface (LEDset generation 2) is a standardized LED module interface to set the right output current and establish an easy and low-cost temperature protection for the connected LED module. This multi-vendor interface is suitable for LED modules connected in parallel or series. Note: In the following figures, the LED module is displayed in a simplified way. The real number of LEDs depends on the output voltage of the driver. Figure 6: LEDset2 parallel connection Luminaire 1 4DIMLT2 E L N SD(2) DA DA LED+ LED- LED- Rset It is possible to set a current lower than the minimum rated current (see warning in chapter 1.4). This operating current is indicated by a red number as shown in figure 5. Figure 5: Setting of a current lower than the minimum rated current LEDset 2.1.1 Fixed current mode To use the fixed current mode, it has to be selected in the Tuner4TRONIC® software. The minimum and maximum rated output currents are displayed according to the selected LED driver. The output current of the LED driver can be set by changing the value in the “Operating Current” field. NTCset Without any resistor connected to the LEDset2 interface, the factory default current is 700 mA. As soon as the LED driver detects a resistor value for more than 3 seconds within the valid resistor range of 2.37 kΩ (1050 mA) and 24.9 kΩ (200 mA), it switches to the LEDset2 mode. Rset LED module LED module Figure 7: LEDset2 series connection Luminaire 1 4DIMLT2 E L N SD(2) DA DA LED+ LED- LED- LEDset NTCset Rset Rset LED module LED module 8 4DIMLT2 LED drivers | Features The output current of the LED driver can be set using an externally connected resistor (min. power rating 50 mW, max. tolerance 0.5 %). This provides the possibility to set the LED current manually without the need for an additional programming of the LED driver. With a resistor mounted on the LED module as shown in figure 8, the correct LED current can be set automatically. With this resistor, the desired current for the LED module is set according to the used LED bin and needed lumen output, offering a real plugand-play solution and making the system future-proof. The LEDset2 coding for the 4DIMLT2 family is shown in the following graph. Figure 10: LEDset2 coding 1 Undefined range Output current [mA] 2 Nominal range 1000 800 Figure 8: Rset connection Luminaire 1 1 600 4DIMLT2 E 400 L N SD(2) DA DA LED+ LED- LED- LEDset NTCset 2 200 0 1 10 100 Rset [kΩ] Assuming a tuning factor of 100 %, the corresponding output current can be calculated with the following formula within the valid resistor range (Rset = 2.37–24.9 kΩ): Rset I out [A] = LED module 5 V Rset [Ω] x 1000 The undefined range should be avoided because the output current of the LED driver is not predictable. To achieve a more accurate current setting, the second LED- terminal of the LED driver can be used as shown in figure 9. This increases the accuracy by roughly 0.5 %. Table 5 gives an overview of commonly used current values and the appropriate resistor values.

Rset LED module 9 4DIMLT2 LED drivers | Features 2.1.3 Tuning factor In combination with the LEDset2 operating mode, the tu ning factor provides a real added value. To minimize the number of LED module variants, the tuning factor can be used to adapt the light output of standardized LED modules (e.g. Zhaga modules). The normalized luminous flux of the module can be set to the required light output of the application. Output current [mA] = LEDset2 current [mA] x tuning factor [%] Warning: In case the tuning factor is set higher than 100 %, the reliability and safety of the module needs to be checked. In case the set operating current multiplied with the tuning factor exceeds the maximum nominal output current of the LED driver, the LED driver will limit the output current to the maximum nominal output current. Figure 11: Tuning behavior LEDset2 current 1050 mA 2.2 Thermal derating and protection 700 mA 500 mA Example: If 7000 lm are needed, a standardized 8000-lm LED module with a tuning factor of 87 % can be used to achieve this requirement. Every time the 8000-lm module is replaced (also with a different default current), the current of the LED driver (light output of the LED module) will be reduced by 87 % and the system is adapted to roughly 7000 lm. This enables an easy replacement in the field without reprogramming, while having a low number of LED module variants on stock. 500 mA 350 mA 0 mA Time Tuning factor 150 % 2.2.1 External temperature sensor By connecting an external temperature sensor to the NTCset port of the 4DIMLT2 LED driver, a very easy and cost-efficient temperature protection of the LED module can be realized. As an example, an NTC (negative temperature coefficient resistor) can be mounted on the LED module and connected as shown in figure 12. In case the thermal protection feature is enabled and nothing is connected to the NTCset terminal, the driver delivers 100 % light output. Figure 12: NTC connection 120 % Luminaire 1 100 % 4DIMLT2 E L N SD(2) DA DA LED+ LED- LED- 0 % LEDset NTCset 50 % Time Output current NTC 1050 mA 700 mA LED module 600 mA 500 mA 350 mA 0 mA Time Two different thermal protection modes can be selected in the Tuner4TRONIC® software: —— Resistor-based mode (factory default) —— Temperature-based mode 10 4DIMLT2 LED drivers | Features Resistor-based mode The resistor-based mode is activated by default. If the connected resistor sensor value falls in the range between 6.3 and 5.0 kΩ, the output current is continuously lowered down to 50 %. If the value falls further below 4.3 kΩ, the output is switched off completely until the sensor reaches 5.0 kΩ again. The complete switch-off can be deactivated by clicking on the “Shut Off” check box. After selecting the correct sensor type in the Tuner4TRONIC® software, the favored temperature behavior can be programmed as shown in figure 13. Figure 13: NTC programming In this mode, a common NTC can be used to achieve a fixed thermal protection as shown in table 6. The specified temperatures can vary, depending on the used NTC component and the corresponding tolerances.

If the maximum tc temperature is exceeded, the LED driver starts derating the output current down to 30 % for AC supply voltage. If the temperature keeps increasing, the LED driver switches off. It switches back on at the maximum allowed tc temperature. Note: To achieve the lifetime data of the driver, the luminaire manufacturer needs to ensure that the maximum tc temperature is never exceeded. 11 4DIMLT2 LED drivers | Features 2.3 Constant lumen function Over the lifetime of an LED module, the light output drops due to the aging process of the LEDs. To achieve a constant light output of the module, the LED driver stores the operating hours of the LED module and increases the output current to react to the light output drop. To set this feature according to the applied LED module, the Tuner4TRONIC® software can be used as shown, for example, in figures 15 and 16. Figure 17: Constant lumen function – possible savings Figure 15: Constant lumen programming table The exact values for programming the constant lumen function for the connected LED module need to be obtained from the corresponding LED supplier. Figure 16: Constant lumen programming graph (operating time = 10 kh) 2.4 Lamp operating time The LED driver monitors the operating hours of the connected LED module. In case of a fault of the LED driver or module, the lamp operating time has to be (re)set accordingly with the Tuner4TRONIC® software. The lamp operating time also has an influence on the constant lumen function and the “end of life” feature. It can be set using the Tuner4TRONIC® software as shown in figure 18. Figure 18: Lamp operating time (10 kh) The output levels have to be steadily increasing from the beginning to the end. Warning: The output level is indicated as a red number if the level is set higher than 100 %. In this case, the reliability and safety of the module needs to be checked if the nominal operating current is exceeded. It is not possible to achieve a higher output current than the maximum nominal output current of the LED driver. 2.5 End of life The LED driver can indicate that a preprogrammed lifetime of the connected LED module is reached and the module should be replaced. This function has to be activated in advance via the Tuner4TRONIC® software. The “end of life” indication can be programmed as shown in figure 19. Figure 19: End of life setting The output level cannot fall below the minimum physical dimming level of the LED driver, even if the software displays a lower value. By clicking the “Savings” button, the estimated energy savings are calculated as shown in figure 17. This value is only an estimation because it does not consider, for example, the LED Vf behavior and efficiency of the driver. If the specified lifetime is reached, the LED driver indicates this through a lower light output during the first 10 minutes of the switch-on period, as shown in figure 20. 12 4DIMLT2 LED drivers | Features Figure 20: “End of life” behavior without switch-on fade time Figure 22: “End of life” behavior with short switch-on fade time Output level [%] Output level [%] Output current Output current Minimum dimming current Minimum dimming current 10 minutes “end of life” indication Time 10 minutes “end of life” indication Time Switch-on fade time If a switch-on fade time is set, it is overriden by the “end of life” functionality as shown in figure 21. After 10 minutes, the output current is set according to the current switch-on fade time level. Note: In DC operation, the “end of life” indication is deactivated until the next power-on/off cycle or DALI operation. Figure 21: “End of life” behavior with long switch-on fade time 2.6 OEM key By entering the OEM key, all or partial features of the 4DIMLT2 drivers can be protected. The following features are locked by selecting the “partial” lock. —— Constant lumen —— Operating current —— Thermal protection Output level [%] Output current Minimum dimming current 10 minutes “end of life” indication Time Switch-on fade time If the switch-on fade time is shorter than 10 minutes, the output current is directly switched to the nominal output level after the “end of life” indication as shown in figure 22. By factory default, the drivers are not protected by the OEM key. Once it is entered, the configuration can only be reprogrammed with the same OEM key. The valid OEM code key range is from 0001 to 9999. 0000 is reserved to indicate a non-protected device. The protection can be deactivated in the special rework mode of the Tuner4TRONIC® software with a Tuner4TRONIC® production file containing no OEM code key. Note: Once a wrong OEM key has been entered to reprogram the driver, the reprogramming gets locked for some seconds until the code can be entered again. 13 4DIMLT2 LED drivers | Operating modes 3 Operating modes The operating modes of a 4DIMLT2 LED driver can be selected using the Tuner4TRONIC® software. Only one mode can be selected. Figure 23: Operating/dimming modes 3.1 On/off operating mode 4DIMLT2 LED drivers can also be used in a simple on/off operating mode. One of the following dimming modes needs to be selected: Note: DALI always has a higher priority than the selected operating mode and can be activated by a valid DALI command in every mode. After a power-off/on cycle, the LED driver operates in the originally selected dimming mode again. — StepDIM/AstroDIM/DALI (wiring selection) – DALI and SD(2) port not connected — StepDIM (DALI) – DALI and SD(2) port not connected — DALI – DALI port not connected The LED driver offers the possibility to select one of the two dimming modes “StepDIM (DALI)” or “AstroDIM (DALI)” via external wiring in case the default dimming mode “StepDIM/AstroDIM/DALI (wiring selection)” is set. Please see chapter 3.2.1 for wiring information. Note: Be aware that the parameters set in these operating modes also have an influence on the behavior of the LED driver in the on/off operating mode. Figure 24: Wiring for on/off operation Luminaire 1 Luminaire 2 4DIMLT2 E 4DIMLT2 E L N SD(2) DA DA LED+ LED- LED- LEDset NTCset L N SD(2) DA DA LED+ LED- LED- LEDset NTCset LED module LED module PE L1 S1 N Switching cabinet 14 4DIMLT2 LED drivers | Operating modes 3.2 AstroDIM feature The AstroDIM feature allows an autonomous dimming without the need for an additional control line. The 4DIMLT2 LED drivers support up to five independent dimming levels and flexible settings of fade times between the individual dimming levels. The LED driver does not have a real-time clock. The internal reference clock is derived from the mains frequency and the driver detects if it is connected to a 50 Hz or 60 Hz supply system, assuming a time base of 20 ms or 16.6 ms. This allows a synchronized switching of all units. In case of DC operation (see chapter 3.6), the dimming mode is stopped until the AC voltage is applied again and a poweroff/on cycle is performed. The output levels can be set to 0 % (OFF) or between 10 % and 100 % in steps of 1 %. Warning: If the output level is set below the minimum physical dimming level of the LED driver (except OFF), the minimum dimming current is used. The software still displays the original value. If the output level falls below the minimum allowed dimming current, the value is visualized in red. In addition, switch-on and switch-off fade times can be programmed at the beginning and the end of a switching cycle to allow for further energy savings during the twilight phase. This function is also helpful for installations with a pedestrian crossing where no specific infrastructure is available to switch the pedestrian crossing illumination independently of the rest of the street light illumination. 3.2.1 Wiring and feature activation There are two ways to activate the AstroDIM mode: Two different modes for AstroDIM are supported: — Option 1: By external wiring Selected dimming mode (factory default): “StepDIM/AstroDIM/DALI (wiring selection)” — Option 2: Via the Tuner4TRONIC ® software Selected dimming mode: “AstroDIM (DALI)” or “AstroDIM PD (DALI)” Time-based: The dimming profile defined in the reference schedule is referenced to the switch-on time of the LED driver. Astro-based: The dimming profile defined in the reference schedule is referenced to the annual average middle of the night, which is calculated based on the theoretical sunrise and sunset times. For option 1, the AstroDIM feature is activated without the need for programming. Only a permanent connection between the L and the SD(2) port of the LED driver is necessary (see figure 25). If the SD(2) port is not active during the start-up phase of the LED driver (for 1 s), the StepDIM feature is activated instead of the AstroDIM feature. Information on the default dimming profile can be found in the datasheet of the applied LED driver. For option 2, the external wiring can be avoided if either the “AstroDIM (DALI)” or “AstroDIM PD (DALI)” dimming mode is selected via the software (see figure 26). Figure 25: Wiring: StepDIM/AstroDIM/DALI (wiring selection) Luminaire 1 Luminaire 2 4DIMLT2 E 4DIMLT2 E L N SD(2) DA DA LED+ LED- LED- LEDset NTCset L N SD(2) DA DA LED+ LED- LED- LEDset NTCset LED module LED module PE L1 S1 N Switching cabinet 15 4DIMLT2 LED drivers | Operating modes Figure 26: Wiring: AstroDIM (DALI) or AstroDIM PD (DALI) Luminaire 1 Luminaire 2 4DIMLT2 E 4DIMLT2 E L N SD(2) DA DA LED+ LED- LED- LEDset NTCset L N SD(2) DA DA LED+ LED- LED- LEDset NTCset LED module LED module PE L1 S1 N Switching cabinet 3.2.2 Time-based mode In this mode, the LED driver performs the dimming profile defined in the reference schedule based on the switch-on time of the unit. Five independent output levels can be set for each step. The minimum length of one dimming period has to be longer than the AstroDIM fade time. The maximum duration of the schedule is 23 h and 59 min. If less than five output levels need to be performed, two sequenced levels have to be set to the same value. The AstroDIM dimming profile in the time-based mode already starts after the first power-off/on cycle after programming. Figure 27: Time-based AstroDIM Fade timing: — AstroDIM fade time: Fade time between the different dimming levels. — Switch-on fade time: Fade time after the power-on of the LED driver. The output level at the end of this fade time is defined by the output level of the corresponding dimming period. Table 9: Fade timing parameters (time-based mode) Parameter Min. Max. Default AstroDIM fade time 0, 2 s 8 min 3 min Switch-on fade time 0, 15 s 60 min 0s 16 4DIMLT2 LED drivers | Operating modes 3.2.3 Astro-based mode In this mode, the LED driver performs a dimming profile based on the daily power-on and power-off times. The dimming schedule is adapted according to the length of the night. The Tuner4TRONIC® software calculates the annual average middle of the night based on the theoretical sunrise and sunset times, which are related to the location selected in the software. Based on this average middle of the night, five independent dimming periods can be defined in the reference schedule. The minimum length of one dimming period has to be longer than the AstroDIM fade time. Valid time values can be set between 12:00 pm and 11:59 am. If less than five output levels need to be performed, two sequenced levels have to be set to the same value. The defined dimming profile is already performed after the second power-off/on cycle after programming. Figure 28: Astro-based AstroDIM Fade timing: — AstroDIM fade time: Fade time between the different dimming levels. To achieve further energy savings in the twilight phase, the switch-on and switch-off fade time can be set to up to 60 minutes. — Switch-on fade time: Fade time after the LED driver has been powered on. The output level at the end of this fade time is defined by the output level of the related dimming period (step x). — Switch-off fade time: Fade time prior to the estimated power-off point. The switch-off fading is performed down to the minimum dimming current until the LED driver is switched off externally. The “schedule by day” in the AstroDIM feature tab calculates the estimated dimming behavior for a specific day based on the theoretical sunrise and sunset times. If daylight saving has to be considered, the corresponding check box needs to be ticked. The LED driver itself is not able to detect summer and winter time and does not have an internal real-time clock. In case the installation is not powered on and off at the calculated sunrise and sunset times, the correct values can be entered in the manual mode as shown in figure 29. Figure 29: Schedule by day Table 10: Fade timing parameters (astro-based mode) Parameter Min. Max.

It starts after the first valid night and reaches its maximum precision after 8 valid days. A valid on-time is defined if the duration of the operation is longer than 4 hours and shorter than 24 hours. 17 4DIMLT2 LED drivers | Operating modes Figure 30: Use cases of AstroDIM mode Output level [%] The AstroDIM profile is performed after the first valid on-time. 12 3 45 Mains Night 1 Night 2 Time Day 2 Time On First power-on Off Day 1 Case A Output level [%] Voltage dips of less than 100 ms do not affect the on-time (case B).

Note: If the 4DIMLT2 LED driver is operated longer than 24 hours, it cannot be assumed that the different dimming level will start at the same time, because the time base is affected by the accuracy of the mains frequency over the day, week, month and year. 19 4DIMLT2 LED drivers | Operating modes 3.2.4 Presence detection in AstroDIM mode In the “AstroDIM PD (DALI)” dimming mode, it is possible to override the dimming profile of AstroDIM with the presence detection settings triggered by an external sensor (e.g. motion or presence sensor) that is connected to the SD(2) port. The sensor must support the electrical characteristics of the SD(2) port. Figure 31: AstroDIM wiring with presence detector Luminaire 1 Luminaire 2 4DIMLT2 E 4DIMLT2 E L N SD(2) DA DA LED+ LED- LED- LEDset NTCset L N SD(2) DA DA LED+ LED- LED- LEDset NTCset LED module LED module PE L1 S1 N SD Switching cabinet L N L' Sensor Figure 32: Presence detection in AstroDIM mode An active signal at the SD(2) port (PD signal) starts the presence detection profile, which is defined by the following four parameters: — PD level: Output level when the SD(2) port is active. — Start fade time: Fade time after the SD(2) port has become active. — Hold time: Hold time after the SD(2) port is not active anymore. — End fade time: Fade time after the hold period. These parametere can be set using the Tuner4TRONIC® software as shown in figure 33. Figure 33: Presence detection configuration 20 4DIMLT2 LED drivers | Operating modes 3.3 StepDIM feature StepDIM is a one-step dimming mode using an additional control line or a switched phase (pilot line) to control one or more light points and set the light output to a preprogrammed light level.

The software still displays the original value. If the output level falls below the minimum allowed dimming current, the value is visualized in red. For StepDIM operation, the LED driver is connected to the mains and a control line or a switched phase. Figure 34 shows the connection for the two different supply voltage systems.

Leaving the SD(2) port floating (SD inactive), the output level is set to the nominal level. 120 VAC, 60 Hz 220–240 VAC, 50/60 Hz 277 VAC, 60 Hz – Not supported Supported The StepDIM port (SD(2)) of the 4DIMLT2 LED driver is triggered by an input current referenced to the neutral (N) and, if the signal is stable for more than 500 ms, the SD(2) port fulfills the following electrical characteristics: Table 13: Electrical characteristics of the StepDIM port (SD(2)) StepDIM signal Input current SD(2) port Input voltage SD(2) port (SD(2)-N) Active (high) > 2.0 mA peak or > 196 VAC Inactive (low) < 0.5 mA peak – In some installations, leakage currents might occur between the different phases due to old or damaged cables, which have insufficient insulation or high-capacitance coupling. The unit can be triggered if the leakage currents exceed the inactive SD(2) input current. False triggering can be avoided by connecting the SD(2) input to the neutral or using a bypass capacitance/resistance between SD(2) and N. — Nominal level: Output level when the SD(2) port is not active. — SD level: Output level when the SD(2) port is active. — Switch-on fade time: Fade time after power-on. — Start fade time: Fade time after the SD(2) port has become active. — Hold time: Hold time after the SD(2) port is not active anymore. — End fade time: Fade time after the hold period.

If the output level falls below the minimum allowed dimming current, the value is visualized in red. 22 4DIMLT2 LED drivers | Operating modes 3.3.2 StepDIM inverse For the “StepDIM inverse (DALI)” mode, the behavior is inverted. If the switch (S2) is opened and the SD(2) port is floating (SD inactive), the output level is set to the SD level. If a phase voltage is applied to the SD(2) port (SD active), the output level is set to the nominal level. Figure 37: “StepDIM inverse” behavior — Nominal level: Output level when the SD(2) port is active. — SD level: Output level when the SD(2) port is not active. — Switch-on fade time: Fade time after power-on. — Start fade time: Fade time after the SD(2) port is not active anymore. — Hold time: Hold time after the SD(2) port has become active. — End fade time: Fade time after the hold period. 3.3.3 StepDIM inverse, autodetect In the “StepDIM inverse, autodetect (DALI)” mode, the LED driver automatically detects if it is used in a simple on/off environment or in a StepDIM inverse installation. If a valid “high” signal (SD active) is detected at the SD(2) port for longer than 20 minutes, the LED driver automatically switches to the “StepDIM inverse” mode. Figure 38: “StepDIM inverse, autodetect” behavior Level [%] SD nominal level SD level > 20 min Mode Mains SD < 20 min On/off mode StepDIM inverse mode 23 4DIMLT2 LED drivers | Operating modes This feature allows minimizing the number of different luminaire configurations and keeps the stock lean. Example: In some parts of StepDIM installations (e.g. roundabouts or pedestrian crossings), the light output of the installed fixtures should not be reduced during the night. With the “autodetect” feature, all LED drivers can be programmed with the same settings: While the on/off fixtures (SD(2) port not connected) still provide the full light output, the others perform the requested dimming profile. 3.3.4 Mixed StepDIM installations with 3DIM and 4DIMLT2 LED drivers Due to improvements in the circuit robustness of the StepDIM port of the 4DIMLT2 LED drivers compared to the previous 3DIM generation, it is not possible to operate 3DIM and 4DIMLT2 LED drivers on the same SD line without an additional relay on the SD port of the 3DIM drivers. As mentioned in the 3DIM application guide, it is necessary to install an additional relay in mixed installations to separate the SD port of the 3DIM driver from the pilot or control line (see figure 39). This is also valid for drivers whose control port for the pilot line is not referenced to N (see unkown ECG in figure 39).

In the MainsDIM operating mode, the output current of the LED driver depends on the mains input voltage. Standard electronic drivers compensate for fluctuations in the input voltage and do not support this function. No additional control wires are needed in this dimming mode (see figure 40).

The software still displays the original value. If the output level falls below the minimum allowed dimming current, the value is visualized in red. 25 4DIMLT2 LED drivers | Operating modes Figure 41: MainsDIM sample programming Note: To increase the light output stability against small voltage fluctuations, a minimum voltage difference of 5 V from the “start voltage” is necessary to trigger the dimming of the LED driver. The triggering of the dimming is performed with a delay time of approximately 1 to 2 seconds. The setting of the thresholds should also consider the voltage drop in the real installation due to cable and contact resistance. 3.5 DALI operating mode For DALI operation, the 4DIMLT2 LED driver is connected to the mains and to a DALI controller (e.g. Street Light Control system) or DALI bus (see figure 42). The additional DALI wires can be installed alongside the mains wires. Figure 42: DALI wiring Luminaire 1 Luminaire 2 4DIMLT2 E 4DIMLT2 E L N SD(2) DA DA LED+ LED- LED- LEDset NTCset L N SD(2) DA DA LED+ LED- LED- LEDset NTCset LED module LED module PE L1 S1 N DALI bus/ controller Switching cabinet 26 4DIMLT2 LED drivers | Operating modes 3.6 DC operation feature (in preparation) 4DIMLT2 drivers are prepared for DC grid operation. As the built-in 4DIMLT2 LED driver fuse is not rated for DC operation, an external rated DC fuse is necessary. OSRAM is working on an improved firmware version to support common DC grid suppliers, which is expected to be available in April 2016. Currently, it is not recommended to use the drivers in DC operation. Up to 64 DALI LED drivers can be controlled via a two-wire control line – individually, jointly or in up to 16 groups. All of them are connected in parallel to the two DALI wires. DALI connections are not polarized. Therefore, plus and minus do not have to be checked. The maximum allowed wire length between two DALI LED drivers is 300 m. In case of problems, a DALI repeater has to be used. The lighting can be switched on/off and dimmed via the DALI control line. A logarithmic (default) or linear dimming curve can be set. Additional status information can be read out and exchanged between the LED driver and the control unit. The DALI mode always has the highest priority. The LED driver switches to the DALI operating mode as soon as a valid DALI command is received. The DALI mode is maintained until the next power-off/on cycle. The dimming behavior is set to the logarithmic dimming curve by default. Note: The 4DIMLT2 family does not support the OSRAM Touch DIM® functionality. Warning: If the output level falls below the minimum physical dimming level, the minimum physical dimming level is used by the LED driver. The software still displays the original value. If the output level falls below the minimum allowed dimming current, the value is visualized in red.

To ensure a safe and stable hold of the wires, the insulation of the cables should be stripped accordingly.

Incorrect wiring between LED+ and LEDset or NTCset can irreversibly damage the LED driver. If there is a short circuit between LED+ and LED-, the LED driver shuts down and tries to switch the load back on. The same behavior might occur if the output voltage falls below the minimum allowed voltage. 4.4 Input overvoltage In case the supply input voltage exceeds 305 VAC, the LED driver shuts down to indicate an unbalanced load condition. The 4DIMLT2 LED driver can withstand up to 350 VAC for a maximum of two hours. 4.5 Surge protection 4DIMLT2 LED drivers offer a common mode protection level of up to 10 kV (1 pulse) with a unique integrated overvoltage suppression for the connected LED module, which minimizes the stress on the LED module and thus ensures high reliability in the field. To achieve the surge protection levels, the EQUI pin needs to be connected to the heat sink of the LED module (see figures 47 and 48). For the protection levels and test conditions mentioned below, the voltage stress between the LED module and the heat sink can be kept below 0.5 kVpeak. The EQUI pin meets the insulation requirements for protection class I and II luminaires. The protection level between L and N or SD(2) and N is 6 kV. In addition, the SD port contains an active surge suppression element referenced to N. In case an external overvoltage protection device (SPD) is used to protect the DALI port and the mains input, the protection level UP of the SPD between DALI port to earth and mains input to earth should be equal. Connecting only an external SPD to the DALI port with a connection to earth is not allowed. The following protection levels can be achieved for class I and II luminaires: Table 17: 4DIMLT2 surge protection levels Surge between Test condition acc. to EN 61547 L-N 6 kV at 2-Ω source SD(2)-N 6 kV at 2-Ω source L-EQUI/SD(2)-EQUI/N-EQUI 8 kV at 12-Ω source Surge between Test condition acc. to EN 61000-4-5, 1 pulse 1.2/50 µs L-EQUI/SD(2)-EQUI/N-EQUI 10 kV at 12-Ω source If an additional external surge protection device is used, please contact your OSRAM sales contact for support.

This software consists of the following software packages: —— T4T – Development —— T4T – Production —— T4T – Dynamic Link Library (DLL) —— T4T – Command Line Version Performance check: If electronically controlled control gears are combined with electrical power supplies, the electronic circuits of both devices might influence each other. This could lead to wrong measurements (e.g. lower power factor compared to the mains grid). In order to avoid these effects, a mains filter should be installed after the electrical power supply. After registration, the software can be downloaded from the www.myosram.com portal. For more information on the programming of 4DIMLT2 LED drivers, please consult the Tuner4TRONIC® manuals.

They need to be supplied either with the mains input voltage (case A) or with an SELV DC voltage (case B). The low voltage allows for safe programming without the need for additional precautions during production. Warning: In case of partial programming, the SELV DC voltage (case B) needs to be applied to the LED driver for at least 4 seconds. For programming with the mains input voltage (case A), the OT 90/170-240/1A0 4DIMLT2 E only needs an LED load connected. This is not the case for the SELV DC voltage (case B).
