While the DALI® interface is used for integration into bidirectional telemanagement systems, the StepDIM function utilizes an external control line to switch between two lighting levels. This enables an easy replacement for halfnight switch solutions (Bi-Power) of conventional control gears. The third option – the autonomous, self-adjusting AstroDIM function – reduces the lighting level without any external control signal. The control software executes a dimming profile preset by OSRAM or specified by the user via the 3DIM Tool. DALI StepDIM Required infrastructure OSRAM has implemented the 3DIM feature in two control gear families, covering the main fields of application: • POWERTRONIC® (PTo) for HPD lamps • OPTOTRONIC® (OT) for LED modules Telemanagement Wiring for ON/OFF + control line Wiring for ON/OFF AstroDIM 3DIM light management DALI® Digital interface for integration into telemanagement systems StepDIM Dimming via an external control line AstroDIM Dimming without an external control signal, via an internal timer Figure 1: Suitable infrastructures for the use of 3DIM ECGs.

DALI® – digital addressable lighting interface Lumen DALI® is an international standard communication protocol for electronic control gears. It is defined by the standard IEC 62386. In street lighting applications, DALI® is used for bi-directional communication between the ECG and telemanagement systems, which allow for fully customized lighting and monitoring of individual light points. Time ® Figure 3: DALI operation – light output over time (example). DALI® controller Control center IP connection (e.g. GPRS) DALI® control line Power line Wireless Figure 4: DALI® installation. StepDIM is used in installations where a dedicated control line (switched phase) is available in addition to the power line. The switched phase is connected via an external relay to the SD terminal of the 3DIM ECG and an external actuator is used to start and end dimming. The dimming parameters (e.g. dim levels and fade times) are preset by OSRAM and can be modified via the 3DIM Tool. Lumen 1.2.

Control line Figure 6: Installation with external control line for StepDIM operation. 6 DESCRIPTION AstroDIM is designed for dimming without any external control wiring. Therefore, AstroDIM helps to save energy and reduce light pollution, even if only a power line is available. In AstroDIM operation, the ECG executes a preset dimming profile, which can be reconfigured via the 3DIM Tool. The autonomous dimming is regulated by an integrated timer (no real-time clock), which adjusts the dimming profile according to the previous night (operation from switch-on to switch-off). With the 3DIM Tool, it is possible to activate two independent dim levels. Lumen 1.3.

Figure 8: Installation without external control line for AstroDIM operation. 7 3DIM INTERFACE (ECG TERMINALS)/MODE SELECTION 2. 3DIM interface (ECG terminals) The wiring depends on the desired functionality (DALI®, StepDIM or AstroDIM) and purpose of use (operation or configuration). The different wiring options are described in chapter 4. All 3DIM ECGs have a terminal block for connection. The individual terminals are marked as shown in table 1. Table 1: Designation of terminals* DA DALI® Terminals for DALI® connection SD StepDIM Terminal for StepDIM or AstroDIM operation L Line N Neutral DA Terminals for power supply * The order of the terminals depends on the ECG type. Please refer to the datasheet of the selected ECG. 3. Mode selection All 3DIM ECGs are able to perform only one mode (DALI®, StepDIM, StepDIM inverse or AstroDIM) at a time. For comissioning of the ECG it is possible to select the mode via external wiring or with the 3DIM Tool. By default, the ECG is operated according to the so-called “StepDIM/AstroDIM/DALI (wiring selection)”. 3.2. Via 3DIM Tool software The following operating modes can be selected via the 3DIM Tool: • “StepDIM/AstroDIM/DALI (wiring selection)” • “AstroDIM/DALI” • “StepDIM/DALI” • “StepDIM inverse/DALI” • “DALI” 3.1. Via wiring selection (factory settings) • DALI® is always supported and has priority over the other functions (even if AstroDIM or StepDIM are executed). As soon as a valid DALI® command is sent to the ECG, it switches immediately to DALI® operation. During this switch, the output level of the ECG is not changed unless initiated by another DALI® command. Note: After a DALI® command has been received, the ECG stays in DALI® operation until it is switched off. • The AstroDIM function is selected by establishing a permanent connection between phase (L) and the SD terminal of the ECG inside the luminaire compartment (see chapter 4.3.). It is activated as long as no DALI® command is received. • StepDIM is operated via a dedicated control line or a switched phase (in combination with an external relay), which is not powered during the start-up phase of the ECG (at least 1 s). For more details go to chapter 4. Notes: • The factory settings can vary depending on the specific ECG. • Not all ECGs are able to run all operating modes. • A typical half-night switch application (Bi-Power) requires the “StepDIM inverse/DALI” mode, which can only be set with the 3DIM Tool. For more details, please refer to the datasheet or instruction sheet of the respective ECG. 8 WIRING AND CONFIGURATION OF THE ECG 4. Wiring and configuration of the ECG 4.1. DALI® – digital addressable lighting interface 4.1.1. Wiring For DALI® operation, the 3DIM ECG (OPTOTRONIC® for LED modules or POWERTRONIC® for HPD lamps) is connected to the mains and to a DALI® controller or DALI® bus. The SD terminal is left unconnected. The LED module or HPD lamp is connected to the output terminal of the respective ECG. Note: DALI® connection has to be considered at the interface between luminaire head and pole. OPTOTRONIC® 3DIM ECG OT ECG LED module LED out L Mains 50/60 Hz N ® Up to 64 DALI electronic control gears can be controlled via a 2-wire control line – individually, jointly or in up to 16 groups. All of them are connected in parallel to the two wires (see chapter 4.1.2.). DALI® connections are not polarized. Therefore, plus and minus poles do not have to be checked. The lighting can be switched and dimmed via the DALI® control line. Additional status information can be read out and exchanged between the ECG and the control unit. The type of status information that can be exchanged depends on the ECG or the control unit. SD DA DA DALI® bus/ DALI® controller Figure 10: DALI® installation with OPTOTRONIC® 3DIM ECG.

Control line – cable requirements The maximum total cable length of a DALI® control line is 300 m. When selecting a cable, it must be ensured that the voltage drop on the control line does not exceed 2 V at 250 mA.

Connection via power-line converter If the power line is used to transmit the DALI® signal to the luminaire, a power-line-to-DALI® converter is required to control the 3DIM ECGs. OPTOTRONIC® 3DIM ECG OT ECG LED module In order to ensure proper power line communication, a filter might be necessary to decouple the low mains input impedance of the ECG from the power-line-to-DALI® converter. Note: The used power line to the DALI® converter should provide at least the same surge withstand capability as the 3DIM ECG.

StepDIM – midnight step-down/ half-night switch OPTOTRONIC® 3DIM ECG 4.2.1. Wiring For StepDIM operation, the ECG is connected to the mains. The DALI® terminals are left unconnected. The dedicated SD terminal is connected to a control line or a switched phase via an external relay. The relay needs to be selected in a way that it is not switched and held by the occurring leakage currents in the installation. Note: SD connection has to be considered at the interface between luminaire head and pole. OT ECG LED module LED out L Mains 50/60 Hz N SD Dimming is activated by a control switch. The SD control states HIGH and LOW are defined as shown in table 3. If in the “StepDIM/DALI” mode the switch is closed and phase voltage is applied to the SD terminal, the state HIGH is set and the dim level is reached by the ECG. Leaving the SD terminal floating, the state LOW is set and dimming is not activated. For “StepDIM invers/DALI”, the behavior is inverted. The “StepDIM inverse/DALI” mode, which is the most commonly used one, can be selected via the 3DIM Tool. DA Relay DA Control line Figure 16: Wiring for StepDIM operation – OPTOTRONIC® 3DIM ECG.

Parameter setting via 3DIM Tool The StepDIM operation is defined by three parameters: power-on level, dim level and dim fade time. In addition, StepDIM can be operated according to two different signal logics. Table 4: StepDIM parameters Parameter Description Power-on level Output power level of the ECG (in % of the nominal value of the ECG/ lamp combination) after switch-on via the mains. Dim level* Output power level of the ECG (in % of the nominal value of the ECG/ lamp combination) after the SD state has changed. Via the 3DIM Tool, it is possible to select the “StepDIM inverse/DALI” mode, which reverses the logical relation between the SD control state and the ECG output power level (see figure 20). Dim fade time** Transition time between power-on level and dim level. The power-on level and dim level are set as a percentage of the nominal output current or power (depending on the output type of the ECG). StepDIM polarity The SD control states HIGH and LOW refer to the different output power levels of the ECG. By default, LOW means that the ECG provides the power-on level and HIGH means that the ECG provides the dim level (see figure 19). StepDIM signal logic The polarity of the input signal used for dim activation can be changed → “StepDIM inverse/DALI” mode. * Please note that the dim level is also referred to as “Dim level 1” Note: The power-on level and dim level depend on the nearest admissible DALI® value. Setting an intermediate value results in a rounding to the nearest admissible value (see table below). in the 3DIM Tool. ** Can only be set for OPTOTRONIC® 3DIM ECGs.

AstroDIM – autonomous dimming without external control 4.3.1. Wiring When the AstroDIM function is selected by providing a permanent connection (jumper wiring) between line (L) and the SD terminal of the ECG (see figures 21 and 22), the ECG starts and ends dimming on its own (autonomous operation). It is controlled only by the mains power switch and no additional control lines are required. There is no need to configure the ECG before AstroDIM operation. The ECG starts operating with the default parameters of the AstroDIM function when the power is on. The AstroDIM parameters, e.g. dim levels and fade times, can be modified via the 3DIM Tool by connecting a PC to the DA terminals of the ECG via an OSRAM DALI magic hardware interface. OPTOTRONIC® 3DIM ECG OT ECG LED module LED out L Mains 50/60 Hz N SD DA DA External wiring between L and the SD terminal can be avoided if the “AstroDIM/DALI” mode is selected via the 3DIM Tool (see figure 23b).

In case the ECG is switched on right after the calculated sunset and switched off right at the calculated sunrise, the arithmetic middle of the night is visualized by the 3DIM Tool as a yellow line and can be compared to midnight (see figure 24). 12 Day mark Length of the night 09 Sunrise 8:08 Local time (h) 06 03 Middle of the night 00 Dim levels (dark) 21 Night (bright) 18 Sunset 16:18 15 12 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Figure 24: Length of the night over the year as visualized by the 3DIM Tool. 18 Fade time Fade time End time 2 End time 1 Fade time Fade time Power (%) Every night, the ECG-integrated timer measures the operating time of the ECG (time between switch-on and switch-off).

Frequently asked questions (FAQ) 5.1. General questions 5.3. Questions regarding StepDIM Can the operating mode be changed during operation? This is not possible during StepDIM and AstroDIM operation. Only one mode can be activated at a time. However, it is possible to reset the ECG by a power off/on cycle and activate a different function. What happens if a voltage dip occurs during StepDIM operation in the “StepDIM/AstroDIM/DALI (wiring selection)” mode? When a 3DIM ECG is used in the “StepDIM/AstroDIM/DALI (wiring selection)” mode, a mains voltage dip can result in an unwanted ECG behavior. If the voltage dip takes longer than 200 ms, the ECG will reset itself. Once the mains power is back, two conditions can occur: • If the SD state is LOW during the first 500 ms and then becomes HIGH, the StepDIM mode and state that was present prior to the voltage dip is restored. • If the SD state is HIGH immediately after the ECG is switched on (at least for the first 500 ms), the AstroDIM function is activated. This malfunction is corrected automatically as can be seen in figure 27. The unwanted AstroDIM function does not modify any StepDIM parameters and stops as soon as the power is interrupted. When the power is switched on again, the ECG returns to regular StepDIM operation. This malfunction can be completely avoided if the “StepDIM/DALI” mode is selected and configured with the 3DIM Tool instead of the “StepDIM/AstroDIM/DALI (wiring selection)” mode. What type of clamp can be used for the connection between L and the SD terminal to activate AstroDIM by wiring selection? Any standard clamp that fulfills the luminaire standard IEC 60598 can be used. If an OPTOTRONIC® control gear with SELV-equivalent output is used, the required creepage distance, clearance and insulation thickness need to be considered. 5.2. Questions regarding DALI® Power (%) Are the DA terminals polarized (+ and - pole)? No, the DA terminals are not polarized. Therefore, it is not relevant which wire is connected to which DA terminal. Power-on level Dim level Time (h) Mains Long voltage dip (>200 ms) SD state Time (h) Time (h) Function Malfunction StepDIM AstroDIM Day 1 StepDIM Day 2 Time (h) Figure 27: Long voltage dip – malfunction and ECG reset. 20 FREQUENTLY ASKED QUESTIONS (FAQ) 5.4. Questions regarding AstroDIM If a voltage dip shorter than 200 ms occurs, the load is switched off. However, as soon as the mains power comes back, the load is powered and supplies the same dim level as before the voltage dip. In any case, short dips do not affect the reliability of any 3DIM operation. In case of AstroDIM operation, the voltage dip does also not affect the calculation of the operating time. Dim level % 80 70 60 50 40 30 20 10 0 ON Mains What happens if the voltage dip is shorter than 200 ms? The mains power is likely to be subject to short voltage dips. 3DIM ECGs are designed to withstand at least voltage dips of up to 200 ms without affecting the dimming profile (voltage dips according to IEC 61547). 90 First power-on AstroDIM regular Day 1 Day 2 OFF Time (h) Figure 28: First and second activation of the AstroDIM function. 100 90 80 Dim level % The calculation of the operating time, however, is already available when the ECG is switched on for the second time. The internal timer of the ECG has measured the duration of the first operation and has saved it in its internal memory, thus allowing the smart AstroDIM algorithm to calculate the operating time for the coming night. 100 70 60 50 40 30 20 10 0 ON Mains What happens when AstroDIM is activated for the first time? The AstroDIM function does not work autonomously without having a reference to calculate the operating time of the ECG. Since there is no operating time data available at the time of the first activation, the ECG does not execute a dimming profile, but remains on until the power supply is turned off. OFF Day 1 Day 2 Time (h) Short voltage dip (<200 ms) Figure 29: Operation after a short voltage dip. 21 FREQUENTLY ASKED QUESTIONS (FAQ) 90 80 Dim level % What happens if the operating time in AstroDIM mode is longer than 24 hours? If the operating time of the ECG is longer than 24 hours, it is not saved and therefore not used to calculate the next operating time. This can be the case when the system is installed or tested. Moreover, the dimming profile based on the last valid operating time (shorter than 24 hours and longer than 4 hours) is performed automatically every 24 hours if the ECG is not turned off. 100 70 60 50 40 30 20 10 0 ON Mains What happens if the operating time in AstroDIM mode is shorter than 4 hours? If the operating time of the ECG is shorter than 4 hours, it is not saved and therefore not used to calculate the next operating time. This situation can occur as a result of long voltage dips or during maintenance of the luminaire. Figure 30 shows that normal operation is restored in the following night. OFF Note: Continuous 24-hour operation is not recommended. Day 1 Day 2 Is it possible to reset the AstroDIM operating time memory? For maintenance of the installation, it is required to reset the AstroDIM operating time memory to restore the factory settings. This can be done with the 3DIM Tool. Figure 30: AstroDIM operation shorter than 4 hours. Time (h) What happens if a DALI® operation is stopped and the ECG is configured as “AstroDIM/DALI”?
