GAMMA instabus Technical Product Information September 2019 KNX/DALI Gateway Twin N 141/31 KNX/DALI Gateway Twin plus N 141/21 KNX/DALI Gateway plus N 141/03 5WG1 141-1AB31 5WG1 141-1AB21 5WG1 141-1AB03 These KNX/DALI Gateways are KNX devices with two independent DALI interfaces. Up to 64 DALI actuators (e.g. ECG with DALI interface) and additional DALI sensors (e.g. DALI key interface, presence detectors, etc.) can be connected per channel. DALI (Digital Addressable Lighting Interface) is a bidirectional communications interface to IEC 62386, whose specification was chosen by manufacturers for electronic ballasts. It not only receives, for example, switching and dimming commands, but also transmits status information such as failure of an illuminant or reporting of a detected error in the ballast. The KNX/DALI Gateways enable communication with up to 64 DALI actuators per channel. These can be connected and dimmed in groups. They also make it possible to record and transfer DALI status and error messages. An individual name, a group, parameter and scenes are assigned to individual DALI ECG during commissioning with the ETS (Engineering Tool Software). DALI sensors are also assigned to groups in the ETS (for this, go to the application program description). The integrated power supply unit supplies the gateway electronics and generates the DALI bus voltage. It facilitates operation of the gateway and direct switching and dimming of all DALI ECG's controlled via the DALI interface, even if the gateway has still not been operated with the ETS or if communication via KNX is interrupted. For this, the devices have a key (figure 2, A3) on the front to disable or enable "Direct Mode". If the key is first held down, then the display (A5) indicates direct mode by "". Then, all lights are switched on/off (tap the key) or dimmed (hold the key down) together by the key pair (A7 and A8) and controlled by the DALI bus line via the respective channel A or B. The LED (A4) indicates the switched status of the connected lights. If the "Direct Mode" key is held down for a second time, then the "" in the display goes out and the Gateway is again in bus mode [display ] or in standalone mode, if KNX communication is unavailable. The devices have a voltage detector during initialization, which detects whether a voltage has been applied to the DALI terminals incorrectly. The DALI power supply feeds both ECG and sensors; verify that the maximum permissible current drain by all connected DALI devices is not exceeded. Product and function description Fig. 1 KNX/DALI Gateway Twin plus N 141/21 This document provides information on the full range of functions for the KNX/DALI Gateway Twin plus N 141/21 983405 (Firmware V05) / 983406 (Firmware V06). The range of functions of N 141/03 – 983705 (Firmware V05) / 983706 (Firmware V06) is limited to channel A. Also N 141/31- 983305 and 983D05 (Firmware V05) / 983307 and 983D06 (Firmware V06) is limited. The functions common to all devices are described starting on page 3 and the selectable functions starting on page 8. A table with an overview of the functions for each KNX/DALI Gateway is on the page 6. DALI fundamentals The universal DALI bus (DALI = Digital Addressable Lighting Interface) is a system for controlling electronic switching devices (ECG) in lighting systems. The DALI communication interface specification is set out in the international IEC 62386 standard. A new firmware version if necessary can be loaded to the gateway over KNX.

Additionally, status information for lighting values or error states, such as the failure of a light or an ECG, can be reported via DALI. Sensors with DALI interface are also supported. In a single DALI line, up to 64 individual DALI switching devices (slaves) can be connected through the associated controller/gateway (master). On DALI commissioning, ECGs receive an automatically generated...
