DALI-2 SI PRO - Lunatone Sensor Modul

Lunatone DALI-2 SI PRO / SI-1L PRO Combi Sensor Module – Switching Input for a Floating Contact or Mains Voltage, Flush-Mounting Box and DIN Rail

Integrates sensors with switching outputs into DALI-2 systems as application controllers – with four operating modes for motion and lighting control.

Combi sensor module for qualified electricians and system designers: turns motion detectors, contact switches, light barriers or relays into a DALI-2 lighting control system.

Product Features

• Application controller like the DALI-2 CS – Provides the same functionality and is compatible for synchronisation; the module issues direct DALI control commands that are executed immediately by the DALI drivers.
• Switching input for an external sensor – Sensors with switching outputs can be connected, such as motion detectors, contact switches, light barriers, relays and switches.
• Three versions: floating-contact input (SI PRO) or mains-voltage input (SI-1L PRO, available for flush-mounting box or DIN-rail installation) – The mains-voltage input is galvanically isolated from the DALI circuit.
• Four operating modes – Motion control, motion control with constant-light regulation, constant-light regulation and brightness-threshold control.
• Corridor function – A second light level dims the lighting before it switches off.
• Up to four target addresses simultaneously – Individual addresses, groups or broadcast can be controlled in every operating mode.
• Synchronisation of multiple sensors covering the same area – Up to 8 sensor inputs can be evaluated for each function.
• Switch-on and Bright-Out thresholds from 0 to 1020 lux in 4-lux increments – Motion detection can be adjusted to the ambient brightness.
• Operating behaviour configurable via scenes and external DALI commands – The response to external on, off, dimming and scene commands can be selected for each operating mode.
• Powered via the DALI bus, polarity-independent connection – No additional power supply is required; multiple modules can be used in one DALI circuit.
• DALI-2 motion detector instance (62386-303), DALI-2 certified – The instance sends event messages that can be evaluated by other controllers.

Applications

Motion-Controlled Lighting with Run-On Time

When motion is detected, the module switches the controlled area to an adjustable light level, maintains it for the hold time, dims to the second light level and then switches off.

Constant-Light Regulation and Brightness-Threshold Control

When used with a DALI light sensor (for example, DALI-2 CS), the module regulates the brightness to a setpoint or sends DALI commands when threshold values are reached, for example to close blinds when the incident light is too strong.

Multiple Sensors Covering One Area

When synchronised, the module assumes the master function, while other sensors provide their measured values in slave or instance mode, for example to control the lighting in a corridor.

Outdoor Areas with Brightness-Dependent Control

The Bright-Out threshold ends motion detection in daylight. The data sheet gives the example of a car park that is switched on only when the measured light level is below 70 lux.

Technical Specifications

Comparison of Key Data

Sequence During Motion Detection

When motion is detected, the module switches the area to the first light level (1) and maintains it for the first hold time (2). It then dims to the second light level (3), maintains this level for the second hold time (4) and switches off with the Off command (5). If motion is detected again while dimming or during the second hold time, the module switches back to the first light level. When using constant-light regulation, the absence value should be set sufficiently low so that it does not exceed the regulated value. In its factory-default state, the module operates in motion-controlled mode without constant-light regulation, with the controlled area set to broadcast, the switch-on command set to Recall Max, a hold time of 10 minutes and the switch-off command set to Off.

Light Sensor and Synchronisation

The SI PRO and SI-1L PRO modules do not contain a light sensor. Operating modes with light regulation require a DALI light sensor that reports its values via DALI events. The Synchronisation option is used to define the sensors for motion detection, brightness thresholds and constant-light regulation; the instance settings of the selected sensors are configured automatically by the module. The Sensor Evaluation Mode determines whether the maximum, minimum or average value of the sensor readings is used. DALI-2 CS application controllers used as sensor inputs should be set to slave mode, as synchronisation does not deactivate them automatically.

Behaviour in Response to External Commands

External on, off, dimming and scene commands sent to up to four control addresses can be handled differently depending on the operating mode, for example by ignoring them, disabling control, simulating motion or adopting the light level. Scene commands can trigger alternative behaviour, such as an alternative target address or an alternative setpoint. At power-on, a defined DALI command can be sent or the timed sequence can be started in fast-forward mode. The module can be configured to respond to a DALI reset command in one of three ways: not at all, with DALI standard values or with Lunatone factory settings.

Configuration with DALI-Cockpit

Addressing and configuration are carried out using the DALI-Cockpit PC software via a suitable interface to the DALI bus (DALI-2 USB, DALI USB, DALI-2 WLAN, DALI-2 Display, DALI-2 IoT, DALI 4Net or DALI SCI RS232). For locating the devices, the flush-mounting versions feature an integrated buzzer, while the DIN-rail version has an integrated LED; alternatively, the devices can be identified by their serial numbers.

Wiring must be carried out as a fixed installation in a dry and clean environment. Installation may only be performed by qualified personnel and with the power disconnected; national regulations for electrical installations must be observed. Only one conductor may be connected to each terminal. The DALI signal does not meet the SELV category; therefore, the installation regulations for low-voltage systems apply. The voltage drop on the DALI cable must not exceed 2 V at the maximum cable length (300 m) and maximum bus load (250 mA).
