DESCRIPTION 1. Description The 3DIM feature offers three control and dimming functionalities in a single electronic control gear. 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.
DESCRIPTION 1.1. 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).
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).
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 5. All 3DIM ECGs have a terminal block for connection. The individual terminals are marked as shown in table 1.
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.
WIRING AND CONFIGURATION OF THE ECG 4.1.2. 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. DALI® (DA) Neutral conductor The following table can be used as a quick reference guide for selecting the correct cable cross-section. Protective earth e.g.
WIRING AND CONFIGURATION OF THE ECG 4.1.3. 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.
WIRING AND CONFIGURATION OF THE ECG OPTOTRONIC® 3DIM ECG 4.2. StepDIM – midnight step-down/ half-night switch 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. Note: SD connection has to be considered at the interface between luminaire head and pole. Dimming is activated by a control switch. The SD control states HIGH and LOW are defined as shown in table 3.
WIRING AND CONFIGURATION OF THE ECG The SD control switch shown in figures 18a/b can be a relay connected to a timer with a remote HIGH/LOW voltage signal. Figure 18a shows the setup if only 3DIM ECGs are connected to the SD control switch. In case other ballasts or loads are supplied via the SD line (e.g.
WIRING AND CONFIGURATION OF THE ECG 4.2.2. 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.
Power (%) WIRING AND CONFIGURATION OF THE ECG Fade time Fade time Power-on level The StepDIM parameters (power-on level, dim level and dim fade time) are preset by OSRAM and stored in the ECG. Notes on the factory settings can be found in chapter 3.1. Dim level For exact factory settings, please refer to the datasheet of the respective ECG. Dim duration Time (h) Mains ON The factory settings can be modified by the user via the 3DIM Tool.
WIRING AND CONFIGURATION OF THE ECG 4.3. 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.

WIRING AND CONFIGURATION OF THE ECG 4.3.2. Parameter setting via 3DIM Tool The AstroDIM operation can be individually adjusted by means of the following parameters. Table 7: AstroDIM parameters (dimming profile) Parameter Description Power-on level Output power level (in % of the nominal value of the ECG/lamp combination) after switch-on via the mains.
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). Based on the measured operating times of the previous nights, the AstroDIM algorithm calculates the operating time of the coming night.
FREQUENTLY ASKED QUESTIONS (FAQ) 5. 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.
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.
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.
