OSRAM BT Control |Introduction

1 Introduction

The OSRAM BT Control System represents a new generation of intelligent, independently operating light control systems.

In spite of their compact dimensions, the components of the system are extremely powerful. No matter if the light is controlled

manually by pushbuttons or by fully automatic presence and daylight operation, the OSRAM BT Control System can always

be used in a ﬂexible manner. Compared to conventional, purely switchable solutions, energy savings up to 80 % can be

achieved while enjoying a signiﬁcantly higher lighting comfort.

OSRAM BT Control devices are suitable especially for lighting control at single or group workplaces, corridors, classrooms or

sanitary rooms. Through the integrated Bluetooth Low Energy (BLE) radio module, it is possible to control the light via an iOS

or Android smart phone by the OSRAM BT Control App or to modify the control proﬁle by the OSRAM BT Conﬁg App. Ac-

cess via Bluetooth (BT) can be restricted via password. This guide will show you the most important features and provide you

with troubleshooting instructions.

1.1 The principle

The DALI ECO BT, DALI ECO BT RTC or DALI ACU BT Control device is the central element of the system (application

controller). Based on signals coming from sensors and manual user interfaces, it controls the light level of connected lu-

minaries according to the chosen function mode and its individual parameterization. The integrated software-based regula-

tion algorithms and timers allow an automatic change and optimization of the lighting level.

All settings can be read out and modiﬁed by the OSRAM BT Conﬁg App. Existing conﬁgurations can either be overwritten

completely via proﬁle upload, or only changed by modifying individual parameters.

OSRAM BT Control devices can be adapted in a modular way according to the application requirements or application

size. Thanks to its plug-and-play capability, the control unit starts to detect and conﬁgure connected DALI components

automatically after power-up. Hot-plugging of DALI devices after power-up is not recommended and may lead to an un-

wanted behavior.

OSRAM BT Control |General information

2.4 General installation instructions

2.4.1 Safety instructions

—Please read these operating instructions carefully before installing and using the OSRAM BT Control devices. This is

the only way to ensure that you use the equipment safely and correctly. Keep these operating instructions in a safe

place for future reference. You should make sure that everyone who uses OSRAM BT Control devices has read these

operating instructions.

—Apart from the explicitly mentioned components, no further control units may be connected to the DALI lines.

—OSRAM BT Control devices may only be installed by qualiﬁed personnel who have been appropriately trained and who

have the relevant authority. The installation personnel must be familiar with the operating instructions. Power must be

switched off before any work is undertaken on the system.

—OSRAM BT Control devices units are especially designed for installation within luminaries (DALI ECO BT) or ﬂush-mounted

boxes (DALI ACU BT). An independent installation of DALI ECO BT is only allowed in combination with the mounting kit

ECO CI Kit.

—The relevant safety and accident prevention regulations must be observed.

—If the control cables, sensor cables or the switch and/or the synchronization input is wired with external voltage,

particularly with a mains voltage of 230 V, the unit may be destroyed.

2.4.2 Wiring instructions

DALI, sensor and pushbutton wires must never be connected or applied with mains voltage. Before connecting any new

components, the mains supply of the control unit has to be switched off. After switching on the mains supply, the control

unit automatically detects all connected components. The plug-and-play principle is valid, which means that there is no

need to manually conﬁgure components to ensure a proper operation.

Wiring of the DALI connection

The DALI standard requires basic insulation against mains. To fulﬁll the safety regulations, an additional insulation against

mains is required. For DALI wiring, a cable suitable for line voltage is mandatory (even if in normal condition only 17 VDC

will be supplied). The terminals of the BT Control products are suitable for wire sections of 0.5mm² to 2.5mm². In order to

not reduce the maximum cable length of a DALI installation (300 m), a wire section of at least 1.5mm² is recommended.

DALI wires can be run with line voltage in the same cable. This means that, for example, an NYM-J 5 x 1.5 sheathed cable

(where two wires are used for the DALI communication) is suitable. For DALI wiring, the usage of control and data cables

such as LIYY or bell wire cables such as YR or comparable products are not allowed and a reliable operation may not be

ensured.

Wiring of directly connected pushbuttons

For the wiring of directly connected pushbuttons, a cable suitable for line voltage has to be used. In principle, the pushbutton

wires can be run in the same cable as the mains supply.

In case of longer cable lengths, or in case of incoupling disturbances that lead to a measurable AC disturbance voltage on

the pushbutton wires, which may therefore lead to malfunctions, the usage of a DALI pushbutton coupler (or at least a

separate pushbutton connection cable) is recommended.

The pushbutton wires have to be run locally separated from lamp or LED supply wires. Parallel-running lamp or LED supply

wires may have a negative impact on the pushbutton function.

Wherever possible, crossing of pushbutton wires with lamp or LED supply wires should be at right angles to minimize

capacitive coupling of disturbance signals.

Usage of small-signal or low-voltage pushbuttons is allowed as long as they provide a sufﬁcient isolation (isolation voltage

of at least 1500 V).

Interfaces (wired and wireless) Maximum value

OSRAM BT Control |General information

Do not place any mains voltage or LED supply wires within or close to this area

2) Recommended minimal distance to metal parts

3) Placement of integrated radio transmitter antenna

Guidelines for product placement to optimize the stability and effective range of the BT connection

1. Preferable installation on systems free from metal obstructions or material that heavily weakens the radio frequency

signal (e.g. ﬁber-reinforced plastic).

2. Do not place inside metal boxes!

3. Keep a distance between the antenna area and the mounting surface (see best practice below).

4. Do not wire cables (mains voltage, LED supply wires) near the antenna area and, if possible, out of the device border.

5. Consider an installation height above the furniture and human obstacles (e.g. >1.6 m above the ﬂoor).

Function validation

To validate the assembly, the construction must be checked and the connection stability and connection distance tested.

The check should be done using:

—The OSRAM BT app and a mobile device for testing the range of the mobile device to the BT antenna

—In case of Swarm function: A second BT Control device to test the point-to-point range between Swarm participants

Please note:

The result of the validation is not an index of replicability in all environments and application situations.

2.4.4 Light sensor placement and set point for light regulation

The light sensor measures the sum of daylight and artiﬁcial light reﬂected by a reference surface (e.g. tabletop or ﬂoor).

For this purpose, the sensor must be directed as perpendicularly as possible to the reference surface. To achieve a proper

function, the sensor must be placed so that the sensor receives the reﬂected light of luminaires connected to DALI channel 1.

Direct sunlight falling on the sensor has to be avoided, as well as unwanted measurement of the outside brightness through

the sensor. Therefore, the sensor must not be mounted too close to the window. A sufﬁcient change in the sensor reading

through a change in the illumination is only guaranteed if the maximum mounting height is respected.

Set point adjustment for daylight-dependent control

For the use of the daylight-dependent control function, a set point value must be deﬁned. The set point adjustment must

be performed with minimum daylight and additional light.

Automatic deﬁnition of the set point

Via an automatic setup process, the set point is set to 80 % of the maximum illuminance given by the artiﬁcial light. During

the auto-setup process, the sensor LED ﬂashes red and green alternatingly for about 3 minutes. For a meaningful measure-

ment of the illuminance, it is important that there are no people or objects between the sensor and the reference surface until

the auto-setup process is completed.

Manual adjustment of the set point

The set point for daylight control can be preset individually via the OSRAM BT Conﬁg App.
